Title: Predicting the Body Weight Using Appropriate Regression Model in Beetal Goat Kids Abstract :
This paper deals with designing a cheap and easy-to-attain method to replace weighing for estimating the body mass of goats. Several models on the relationship of heart girth (HG) to live weight (LW) were used and data was collected on 50 Beetal goat kids (25 males and 25 females) of different age groups maintained at organized goat farm in Tarn taran district of Punjab. The animals were divided into four age groups as 0, 1, 2 and 3 months. To predict the body weight of Beetal goat kids four body measurements (height at wither, heart girth, body length and paunch girth) were recorded on each animal which was further used to develop the step wise multiple regression equations. Body measurements varied with increasing age of animals. In goat kids, the highest correlation (r) was observed between body weight and heart girth at 0 (r = 0.701) and 1 (r = 0.762) months of age. Similarly height at wither at 2 month (r = 0.813) and paunch girth at 3 month (r = 0.825) of age.
These correlations between body weight and body measurements were positive and significant (P<0.01). The regression analysis indicated that live weight and body measurements (height at wither, heart girth, body length and paunch girth). Multiple regression analyses were used to calculate the prediction equations. The coefficient of determination (R2) for weight estimation were for height at wither and paunch girth (86.0%) at 3 month. It was concluded that body weight of goat kids can be estimated in field using body measurements taken with a tape in the absence of weighing scales.
Title: Supplementation of Seminal Plasma-Heparin Binding Proteins
to Capacitation Medium Increases In Vitro Acrosome Reaction Percentage in Beetal Bucks Abstract :
This study was focused evaluating the effect of heparin binding proteins (HBP) on in vitro capacitation and acrosome reaction (AR) in Beetalbucks. HBP were purified from pooled seminal plasma of six bucks to evaluate their effect on in vitro capacitation. Semen, washed twice with TALP medium was incubated in TALP, supplemented with glucose, BSA, heparin and HBP for 6 hrs at 37°. A control was also run without HBP. Incubated samples were evaluated for motility, viability, acrosome reaction and inner mitochondrial membrane potential (IMMP) after every 2 hrs. Standardization of HBP concentration on in vitro acrosome reaction revealed 150 μg/ml HBP as an optimum dose. Based on sperm parameters, six bucks were divided into two groups i.e. G-I (> 80% motility) and G-II (<80% motility).There was a significant (p<0.05) decrease in individual motility, viability and high IMMP from zero to six hrs of incubation in both control and HBP treated samples of both groups. A significant (p<0.05) increase in acrosome reaction and medium IMMP was noticeable in control and HBP treated samples with an increase in incubation time. In Vitro induced AR was also significantly (p<0.05) higher in HBP treated samples compared to control in both groups at 4 hrs and 6 hrs of incubation. However, Effect of buck on in vitro capacitation and AR was noticeable in both control and HBP treated samples of G-I and G-II. A non-significant (p>0.05) increase in LPO during capacitation and AR was also observed. This study concluded that SP-HBP enhanced the rate of in vitro AR in beetal bucks.
Title: Non Hormonal Induction of Oestrus in Nellore Ewes Abstract :
A non hormonal induction of synchronization of estrus in ewes of Nellore breed, in two seasons June-July and September – October, covering 39980 and 42370 ewes respectively, spread over 2015 to 2019, with micro minerals (Bioplex High Seven), after onset of monsoon and deworming the sheep, appropriate to the season and type of prevailing parasitic infection, were studied. All the supplemented ewes came to estrus within a week, and were bred with stud rams. After the completion of gestation period all the ewes were lambed within a week uniformly. This may be due to elimination of stress due to environment, nutrition, parasites, replenishment of minerals and stimulation of folliculogenesis with Bioplex. The current extension method induction of estrus is safe, economical, easy to adopt and eco-friendly.
Title: Management of Dystocia due to Primary Uterine Inertia in Bitch: A Case Report Abstract :
A five years old bitch was presented to the TVCC, LUVAS, Hisar with the history of commencement of whelping by delivering a dead foetus yesterday, but after that, no other foetuses or placentae were delivered. Primary uterine inertia was confirmed as a cause of dystocia which was immediately intervened by cesarean section and four dead putrefied foetuses were delivered. The bitch recovered without any postoperative complications.
