Spermatozoa undergoes array of signaling and intracellular pathways and ultimately become competent enough to accomplish fertilization. Hormones, ion channels and signaling molecules in both male and female reproductive tract show bidirectional cross play. The recent discovery of endocannabinoids and their receptors in male and female reproductive system opened new vistas for their research in regulating sperm function. Interestingly, endocannabinoids regulate sperm motility, capacitation, hyperactivity and eventually acrosome reaction. However, their complex intracellular pathways are still to be understood in regulating spermatozoa function. The present review highlights the major breakthrough research in the area of endocannabinoids in male reproduction and in more specific in sperm cells, and their association with regulation of sperm fertilizing competence.

Induced pluripotent stem cells (iPSCs) are promising cell source for cardiac tissue engineering and cell based therapies for heart repair as they can be expanded in vitro and differentiated into most cardiovascular cell types, including cardiomyocytes. During embryonic heart development, this differentiation occurs under the influence of internal and external stimuli that guide cells to go down the cardiac lineage. The aim of this study was to characterize the cardiac differentiation potential of a canine iPS cell. With the use of a standard embryoid body–based differentiation protocol for iPS cells were differentiated for 24 days. In vitro differentiations of canine iPSCs via embryoid bodies (EBs) were produced by ‘Hanging Drop’ method. EB’s were differentiated using 5-azacytidine (5-Aza). During differentiation, EBs were collected on day 4, 6, 8, 12, 16, 20 and 24 to evaluate the expression of cardiomyocyte specific marker. Analyses on molecular, structural, and functional levels demonstrated that iPS cell– derived cardiomyocytes show typical features of ES cell– derived cardiomyocytes. Reverse transcription polymerase chain reaction analyses demonstrated expression of marker genes. The differentiated cells expressed cardiac-specific gene myosin light chain 2 (MYL2) which started from day 8 of differentiation and highest expression was observed on day 16. Immunocytochemistry and relative expression of cardiac specific genes revealed that iPS cells differentiate into functional cardiomyocytes and allow to derivation of autologous functional cardiomyocytes for cellular cardiomyoplasty and myocardial tissue engineering.

Dead and damaged spermatozoa cells present universally in the ejaculates of all eutherian mammals exert toxic effect on contemporary healthy cells mostly through generation of excessive free radicals. This is much more evident during extended period of processing, resulting in poor ejaculate quality. The solution lies in depletion of dead/damaged spermatozoa from the neat ejaculates itself. Thus the objective of the study was to evaluate the efficiency of the protocols such as discontinuous PercollTM density gradient centrifugation (PDGC) and glass wool filtration (GWF) for depletion of dead/damaged spermatozoa from fresh semen in buffalo. Random ejaculates (n=6) of Murrah buffalo bulls were divided into two aliquots after quality assessment: PDGC and GWF protocols (Group I and II, respectively). At the end of the purification protocol, efficiency of the protocols in depleting dead/damaged spermatozoa as reflected by certain quality parameters were evaluated. The mean efficiency (%) of purification protocols based on recovery of spermatozoa was 44.68 and 40.02% for PDGC and GWF, respectively. Moreover significantly (p<0.05) greater values for quality parameters was observed in the Group II (26.4+6.8 vs 68.8+4.4 for acrosome integrity (%); 12.68+6.6 vs 57.7+7.5 for functional plasma membrane integrity (%); 20.3+5.8 vs 80.75+6.7 for viability (%) in Group I and II, respectively). It was concluded that GWF is a better technique than PGDC to filter out dead/damaged spermatozoa from fresh semen with improvement in semen quality and can be a valuable tool in assisted reproductive technology.

Adult body harbors powerful reservoir of stem cells that maintains homeostasis by tissue regeneration and in response to disease and injury. Hair follicle is a dynamic mini organ supporting important biological functions of the body in maintaining homeostasis and skin tissue self-renewal. This study was carried out with the objective of finding the adult stem cells in canine hair follicular tissue. To conduct this study, adult canine skin samples (n=12) irrespective of breed and sex were collected. To characterize the hair follicle stem cells, paraffin sections of canine hair follicles were immunostained with positive hair follicle stem cell markers like Anti- cytokeratin 15 (CK15) and Anti-cytokeratin 19 (CK19) and FITC conjugated and HRP conjugated secondary antibodies were used. Immunoreactivities for CK15 and CK19 were observed in the bulge/isthmus region of hair follicles in between the infundibulum and suprabulbar regions and occupied most part of the peripheral layer of outer root sheath cell. Immunophenotyping of canine Hair Follicle Stem Cells (cHFSCs) in the bulge region of hair follicle helps in confirmation of in vitro culture of cHFSCs from the bulge region which will be further used for translational research.

A total of 150 cloacal swabs were collected from desi chickens, 217 Enterobacteriaceae isolates were identified. The phenotypic antimicrobial resistance among Enterobacteriaceae was studied for 14 selected antibiotics by disc diffusion method. The selection of antibiotics was based on usage of antibiotics in commercial poultry farms and also based on priority of critically important antibiotics in humans. All Enterobacteriaceae isolates were subjected to multiplex PCR - I and II for detection of blaTEM, blaSHV and blaOXA genes and blaCTX-M, group 1 and 2 genes. Predominant β- Lactamase genes in gut microbiota of desi chicken include blaTEM (90.55%) followed by blaCTX-M group I (25.86%) and blaSHV (9.44%) genes. All the samples were found to be negative for blaOXA and blaCTX-M group 2 genes.

Vector borne pancytopenia is emerging as a life threatening entity in animals. In India babesiosis is one among the most prevalent tick-borne parasitic diseases of dogs caused by either Babesia gibsoni or Babesia canis. Bleeding due to thrombocytopenia and the concurrent anaemia and leukopenia were difficult to manage. This study assessed the efficacy of Filgrastim in pancytopenia associated with Babesia gibsoni in dogs presented to the Small Animal Medicine Referral Clinic, Madras Veterinary College. The therapeutic practices included Injection Filgrastim @ 10 µg/kg, SC, SID in combination with the standard triple therapy to manage the pancytopenia and the infection. Twenty numbers of PCR positive Babesia gibsoni dogs were used for this study. The animals were divided in to two groups based on therapeutic practices. First group consisted of dogs treated with triple therapy and the second group consisted of dogs treated and evaluated with Filgrastim along with triple therapy. The study showed that there was a significant increase in leukocyte count in Filgrastim treated group when compared to the other group. Integration of G-CSF along with standard triple therapy helped in better survival in pancytopenic dogs with Babesia gibsoni.

Present study was planned to compare xenogenic decellularized bubaline diaphragmatic scaffold with synthetic polygalactin and polypropylene composite mesh for repair of perineal hernia in dogs. Twelve dogs suffering with perineal hernia were randomly divided in to two equal groups. In group I perineal hernioplasty was done with Synthetic polygalactin and polypropylene composite mesh while in group II, with decellularized bubaline diaphragmatic scaffold (dBDS). Mean surgical time was 59.17 ± 14.04 and 57.50 ± 6.15 minute in group I and II respectively. Swelling, redness and warmth increased significantly (p<0.05) on day 3 in both the groups. In group II initially significantly (p<0.05) increased exudation was observed on day 3 which reduced gradually. Degree of pain after surgery was significantly (P<0.05) decrease on day 3 in both the groups. Neutrophil count was significantly (p<0.05) increased and correspondingly lymphocyte count significantly (p<0.05) decreased on day 7 in group I while in group II no significant difference within the group was observed. Colour Doppler ultrasonographic examination revealed no vascularization on 0 day in both the groups. Neovascularization was observed on day 30 in group I and day 14 in group II on Colour Doppler ultrasonographic examination. It was increased on day 90 in both the groups. The complication encountered in the present study includes local seroma, suture dehiscence due to self mutilation, constipation and fistula formation. Decellularized bubaline diaphragmatic scaffold was well accepted by all the animals and showed less complication than synthetic mesh.

Present study was aimed to evaluate the effect of oral administration of imidacloprid on weekly body weights and hematological parameters in female rats and also to determine the protective role of Withania somnifera against imidacloprid induced toxicity. Forty eight (48) female albino Wistar rats were divided into four (4) groups of twelve (12) animals each. Group 1 served as control, groups 2 was given with imidacloprid at the rate of 30 mg/kg b.wt/day, group 3 was maintained as Withania somnifera (WS) control (1g/ kg feed) and group 4 was treated with both imidacloprid + Withania somnifera (dose as above). The experiment was carried out for a period of 30 days and the test compound was administered daily by oral gavage. Blood samples were collected on 15th and 30th day for hematological analysis. A significant (P < 0.05) reduction in weekly body weights were observed in group 2. Hematology revealed a significant (P < 0.05) decrease in TEC, Hb, PCV, MCV, MCH and MCHC and increase (P < 0.05) in TLC in group 2. The DLC revealed a significant (P < 0.05) increase in neutrophil count and significant (P < 0.05) decrease in lymphocyte count in group 2. Administration of Withania somnifera along with imidacloprid brought moderate protection in all the above parameters.

Present study was undertaken in 120 day-old broiler chicks, randomly distributed into 4 dietary treatments (T1, T2, T3 and T4 supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava @ 0, 2.5, 5.0 and 7.5 % of diet, respectively) each having 3 replicates (10 chicks/ replicate) in a complete randomized block design (CRD). Experimental chicks were fed basal diets (starter and finisher) supplemented with graded levels of LMM. Feed intake, body weight gain and feed conversion ratio (FCR) were recorded at weekly intervals. Two birds from each replicate were slaughtered at the end of feeding trial (42 days). Blood samples were collected and serum separated for biochemical profiles. For histopathological examination, representative tissue samples were collected in 10% neutral buffer formalin and then processed for paraffin embedding employing alcohol as dehydrating agent and xylene as clearing agent. Sections were cut at 4-5µm thickness and stained by routine haematoxylin and eosin method. On histopathological examination of liver, kidney, heart and intestine of T1 and T2 groups showed normal integrity, mild to moderate histopathological changes in T3 group, while, T4 showed drastic histopathological changes. It was concluded that E. jambolana and P. guajava LMM supplementation (2.5% or even 5%) maintained birds performance, minor histopathological changes and producing healthy low cholesterol broiler meat. The LMM incorporation (2.5%) in the diet of broiler chicks may be recommended as socioeconomic, alternative functional feed resource.

The present study was carried out in four genetic groups of cattle, viz. Kangayam, Pulikulam, crossbred Jersey and crossbred Holstein Friesian, to compare the karyomorphological pattern between Bos indicus and Bos taurus x indicus bull calves. Metaphase chromosomal spreads obtained by short term lymphocyte culture technique revealed chromosomal complement (2n) of 60, with 29 pairs of autosomes and one pair of sex chromosomes in four groups. All the autosomes were acrocentric, X-chromosome was sub-metacentric and Y-chromosome was acrocentric in Bos indicus and metacentric in crossbred bulls. There was no significant difference in relative length, arm ratio, centromeric index and morphological index of autosomes and X-chromosome between indicine and taurine groups; but Y-chromosome differed significantly (P˂0.01) in relative length between Bos indicus and Bos taurus x indicus crosses. Y-chromosome polymorphism could help in the determination of breed origin and male lines used in the breeding programmes in order to prevent the possible interferences in the process of reproduction.

Present study was undertaken to study the neurotoxicity of oral acrylamide (ACR) and its amelioration using α-tocopherol, reduced glutathione (GSH) and hot aqueous extract (HAE) of Ocimum sanctum. Forty five male Wistar rats were divided into 12 groups. The study showed a significant reduction in the body weight of the rats fed with ACR in comparison to the other groups while body weight was restored in the rats fed with α-tocopherol and HAE. Neurotoxicity in rats fed with ACR was evident with the results of histopathology and oxidative stress (high MDA and decreased activities of GSH, SOD, GST and CAT in brain). Co-administration of α-tocopherol and HAE lowered these changes however, there was no marked improvement seen in neural damage but improvement was evident in behavioral as well as physiological changes at a marked point. Histopathology of brain in ACR alone fed group showed extensive neural degeneration and massive deposition of fibrin which was substantially decreased and ameliorated with the co-administration of α-tocopherol and HAE. These results support the oxidative stress results as well. Our results suggests that α-tocopherol and HAE can be useful for protecting brain tissue against ACR induced neurotoxicity through minimizing the free radical mediated oxidative stress.

The present investigation was conducted a study on growth performance of weaned kids of Sirohi goat fed with different levels of concentrates for the effect of concentrate feeding on body weight gain. Twenty four kids of Sirohi breed between 3-4 months age were randomly selected on the basis of uniform body weight, age and divided into 3 groups of 8 kids each at the goat farm of S.K.N. College of Agriculture, Jobner. Group T1 served as control supplemented with 50 g concentrate per kid per day for 3 months. Group T2 (treatment) supplemented with 50, 100 and 150 g concentrate and T3 (treatment) with 100, 150 and 200 g concentrate per head per day for 1st, 2nd and 3rd month, respectively. Other management practices were similar for each group. Fodder of khejri loom was offered ad-libitum to all groups. Body weight of kids was recorded weekly. Group T3 fed with more quantity of concentrate achieved the highest (85.77 g/day) average weekly weight gain followed by T2 (69.22 g/day) and control group T1 (61.33 g/day). Maximum average total weight gain per kid was observed in group T3 (7.72 kg) followed by T2 (6.23 kg) and least was found in T1 (5.52 kg). Thus, from above findings it can be concluded that T2 and T3 treatments showed significantly improved growth performance in Sirohi kids and higher level (T3) was relatively the best level in terms of both biological and economical returns.

A study was conducted to improve dietary fibre content of chicken nuggets by incorporating corn bran (CB), dried carrot pomace (DCP) and dried tomato pomace (DTP) as dietary fibre sources. Lean meat was replaced with each dietary fibre source at 3%, 6% and 9% level. One product from each fibre source was selected on the basis of sensory evaluation. Sensory acceptability of 3% fibre treated nuggets was comparable with control and further increase in fibre level resulted in a decline in sensory acceptability. All CB and DCP treated nuggets were harder and firmer than control while 3% DTP treated nuggets were harder than control. Fibre addition resulted in less springier and less cohesive nuggets. Yellowness increased in DCP added nuggets while both redness and yellowness increased in DTP added nuggets. Fibre treated nuggets had less moisture and cholesterol content and higher protein, ash, crude fibre, emulsion stability and cooking yield. pH of DCP and DTP treated nuggets was lower than control. Drastic increase in total dietary fibre and insoluble dietary fibre content was observed in treated nuggets. Sensory scores of nuggets declined significantly while thiobarbituric acid reacting substance value (TBARS) and microbial counts increased significantly during refrigerated storage. It is concluded that incorporation of dietary fibre at 6% level resulted in healthier and fibre enriched nuggets with higher cooking yield and acceptability upto 15th day of refrigerated storage.

The effect of cage or deep litter housing on production performance of White Leghorn was investigated in this experiment. A total 144 pullets of White Leghorn were randomly assigned to two treatments as; Cage housing and Deep litter housing. Results revealed that body weight at sexual maturity was significantly (P<0.05) lower in birds reared in cage than the deep litter housing. Moreover, lower feed intake was observed in birds kept in cages than that of deep litter housing. Feed conversion ratio in terms of feed intake/dozen eggs or feed intake/kg egg mass was better in birds reared in cages than the deep litter housing. The average hen day and hen house egg production were not affected due to different housing systems. Egg quality traits like albumen index, yolk index and Haugh unit score were significantly (P<0.05) higher for eggs produced by birds reared in cage housing than the deep litter housing. The profit of about 20% was observed in cage housing over deep litter housing. It was concluded that the lower feed consumption and body weight at sexual maturity, better feed conversion, egg quality and economic returns were achieved in cages compared to deep litter housing. However, cage or deep litter housing had no effect on egg production.

A total of 4378 cattle and buffalo were screened during period of study (July 2018-June 19). Out of which 27 Pseudomonas aeruginosa were isolated. The isolates were confirmed phenotypically based on pigment production on nutrient agar. These were then confirmed by PCR amplification of species specific oligonucleotide sequences. All the 27 isolates amplified 956bp amplicon 16srRNA Pseudomonas aeruginosa species specific nucleotide sequence. The isolates were also checked for exo and aglD virulence associated genes. All of them amplified 540bp and 313bp amplicon of exo gene and aglD gene. All the isolates were subjected to antibiotic sensitivity testing. Most of the isolates showed highest sensitivity for levofloxacin, streptomycin and enrofloxacin followed by gentamicin, moxifloxacin and amikacin. Neomycin, cefoperazone and ceftriaxone were intermediate in action.

The present study was conducted in the Department of Animal Reproduction Gynaecology and Obstetrics, College of Veterinary Science and Animal Husbandry, OUAT, BBSR in collaboration with ICAR-Central Island Agricultural Research Institute, Portblair (Andaman and Nicobar Island). Crossbred cattle with the history of anoestrus and repeat breeding were considered for the present investigation. The basic difference in serum biochemical and mineral profiles of cattle reared under two quite different ecosystems namely Island and coastal ecosystem was estimated which might be due to the variability in rainfall, ambient temperature, day light length and humidity. The incidence of different infertility conditions in both the ecosystems also might vary as per the environment. Serum samples were collected for estimations of biochemical parameters like total protein, glucose, cholesterol, Ca, P and Ca:P ratio. The overall incidence of infertility was recorded to be 47.62 % in island and 45.90 % in coastal ecosystem. No significant difference in serum levels of total protein, glucose, cholesterol, zinc, copper and manganese could be observed in between cattle reared in both ecosystems. It was concluded that the variations in humidity, ambient temperature, rain fall and day light length between Portblair, Andaman and coastal climate of Odisha, did not have much effect on reproduction of cattle.

The present study describes in- vitro efficacy of Emblica officinalis against Methicillin Resistant S. aureus mastitis. Diffusion technique was used to assess in-vitro efficacy of Emblica officinalis. Zone of inhibition was measured and used to compare the in-vitro efficacy. The zone ranged between 10-13 mm with maximum zone of 13 mm observed in 200 and 225 mg/ml DMSO disc, followed by 12 mm in 175 and 150 mg/ml DMSO disc, 11 mm in 125 mg/ml DMSO disc and 10 mm in 100 mg/ml DMSO disc. The results indicate that the sensitivity pattern for Emblica officinalis at 200 & 175 mg/ml DMSO concentration and was comparable with the standard antibiotics in Methicillin sensitive S. aureus. In Methicillin resistant S. aureus isolates, the zone of inhibition was in the order Oxytetracycline (15mm) followed by Emblica officinalis -200 (13 mm) and Methicillin, ampicillin, gentamicin, ofloxacin were resistance.

The aim of this study was to determine the occurrence of pesticide residues in bovine milk and associated health risks in human. To assess the pesticide residues, a total of 200 milk samples were analyzed using High Performance Liquid Chromatography (HPLC) with Photo Diode Array Detector (PDA).The residues of carbaryl, 4’4’ DDT and deltamethrin pesticides were found in the 27.5%, 11% and 5% milk samples, respectively. The spatial distribution of pesticide residues in milk samples indicated that carbaryl was wide spread over the entire study area. The non-significance differences in mean residual concentrations of all three pesticides in cow and buffalo milk samples were recorded. The human health risk assessment in terms of non-carcinogenic and carcinogenic health hazard was calculated based on both lower bound [LB (mean residue levels)] and upper bound [UB (95th percentile level)] limits at current levels of pesticides in bovine milk samples. The estimated average daily dietary intake (EADDI) of studied pesticides was found below the acceptable dietary intake (ADI) for both adult and children, at mean as well as 95th percentile upper bound (UB) levels. The values suggesting lower carcinogenic and non-carcinogenic health risk to adult however children are at greater health risk.Keywords: Bovine milk, carbaryl, deltamethrin,

L-Selectin (SELL) linked with innate immune mechanism involved in neutrophil migration through endothelium to the site of inflammation. Early recruitment of neutrophils at the site of infection is essential to counteract infection at the earliest in conditions like sub-clinical mastitis (SCM). The present study was framed to evaluate the expression pattern of SELL in naturally occurring SCM in crossbred animals using real time PCR technique. Analysis of data on total leukocyte count indicated leucocytosis condition in SCM affected crossbred cows. Relative expression of SELL on peripheral blood leukocytes revealed a significant 3.16 folds down regulation in SCM affected cows when compared with healthy crossbred cows (P<0.05). The possible reason for leukocytosis in SCM animals might be due to down regulation of SELL on leukocytes reducing their ability to transmigrate through blood vessel to infection site. The result of present study revealed a definite role of SELL in SCM which could be explored for therapeutic aspects in near future.

The present study was conducted at Panna Tiger Reserve of Madhya Pradesh for sero-surveillance for canine parvovirus (CPV), canine distemper virus (CDV) and canine adenovirus (CAV) infections in feral dogs. Biological samples were also collected from the wild carnivore species which were immobilized or died during the study period. Serum samples were subjected for detection of IgG antibodies against CPV, CDV and CAV infections. Additionally biological samples of wild carnivores were subjected to molecular diagnosis of CPV and CDV genes. Seroprevalence for CPV, CDV and CAV infections was observed as 3.5%, 4.4% and 0.89%, respectively, whereas for mixed infections of CPV+CDV, CPV+CAV, CDV+CAV and CPV+CDV+CAV, it was observed as 48.2%, 1.7%, 4.4% and 36.6%, respectively. Sex wise, age wise and distance wise seroprevalence was non-significant in the present study. Seroprevalence for CPV, CDV and CAV infections in cats was observed as 50%, 100 % and 0%, whereas in wild carnivores, it was observed as 100%, 90% and 0% respectively. PCR based diagnosis in the wild carnivore also revealed CDV positive cases. Serological and genomic evidence of pathogens in dogs-cats of buffer villages and wild carnivores of Panna tiger reserve indicated that the viruses may pose a high risk of spillover to wild carnivores. Study also indicated that dog population is immuned to major infectious diseases but can be a threat to the compromised wild carnivore species including tigers.

The binturong or bearcat is the largest species of the family Viverridae. It is uncommon in much of its range and has been assessed as vulnerable on the IUCN red list. The size of the head was small, narrow and light in proportion to the body. The skull of the binturong was dolichocephalic as per the cephalic index (56.25). There was no prominent internasal suture and the orbits were incomplete with optic foramen present near the ventral surface. The mean skull length, skull width, skull base length, cranial length, cranial width, cranial height, were 14.95±0.10 cm, 8.47±0.10 cm, 15.07±0.02 cm, 11.16±0.09 cm, 6.56±0.11 cm, 3.16±0.08 cm, respectively. The mean facial length, facial width, maxilla length, maxilla height, distance between infraorbital foramen, diameter of infraorbital foramina, nasal length, nasal width were 4.95±0.08 cm, 6.14±0.12 cm, 4.46±0.01 cm, 3.83±0.02 cm, 4.68±0.10 cm, 0.49±0.07 cm, 2.94±0.03 cm, 1.97±0.11 cm, respectively. Scanty literature available on morphological and morphometrical studies of the skull of binturong. Therefore this present study was aimed to establish a morphometric database that will eventually guide the use of these measurements for diagnosis and treating different disorders.

Milking behaviour of dairy cows has serious impacts on their production efficiency. A number of genetic and environmental factors controls and influences milking behaviour of dairy cow. The aim of present study was to investigate the influence of housing comfort on expressivity of milking behaviours of cows in parlour, milk yield and compositions. Forty Jersey crossbred cows of similar production levels were selected and divided into 2 groups based on age, production and parity. Subsequently, cows were kept in two different types of loose house; each containing 20 animals. Two types of housing patterns were compared - (i) Traditional shed (T0) and (ii) Thermo-comfortable shed (T1). Impact of housing comfort significantly transformed the expressions of dairy cows behaviour even in milking parlour. Milking temperament scores and stepping during milking were significantly lower in cows kept in T1 compared to that of T0. Cows of thermo-comfortable shed showed more docile, calm and less nervous behaviour than those kept in traditional shed. Housing patterns significantly influenced daily milk yield (kg) being 2.86% more in T1 as compared to T0. Similarly milk compositions were better and significantly higher in T1 group of cows than that of T0. It was concluded that staying comfort of living by resignificantly modulated the expression of dairy cows behaviours even in milking parlour, demonstrated favourable milking temperament, reduced nervousness, enhanced milk yield and showed better milk compositions in Jersey crossbred cows.

The present gross morphological and morphometrical study was conducted on the Harderian gland of chicken. A total of 32 numbers of healthy birds were procured from the Poultry Farm of Nagpur Veterinary College, MAFSU, Nagpur. The chicks were divided into 4 groups viz. 3, 10, 17, and 24 days of age with 8 chicks in each group. It was seen that the Harderian gland was found directed towards ventro-medial aspect of the eyeball in chicks and loosely attached by periorbital fascia to the underlying muscle. The average biometrical observations of left and right Harderian gland in respect of weight, length, width and area of gland were found increased with the advancement of age. Area of the gland increased on its length from 17th day to 24th day of age which resulted into more elongated glands.
