Title: Oral Rabies Vaccines (ORVs), an Alternative to the Parenteral Vaccination Strategy for Rabies Elimination in Stray Dogs - Risk and Benefits in Indian Perspectives
Abstract :
Abstract :
Oral rabies vaccines (ORVs) have successfully eradicated rabies in wildlife, providing significant benefits over parenteral
vaccination by reducing human resources, costs, and time demands. Despite these advantages, ORV use in domestic dogs presents unique challenges due to the higher risk of human exposure, potentially leading to vaccine-associated rabies cases. Limited
genomic surveillance, inadequate screening of non-target animals, and insufficient funding for comprehensive surveillance
impede the detection and reporting of such cases. Simulation models indicate that human risk from 1st and 2nd generation
vaccine-associated rabies is significantly higher—approximately 19 times—when ORVs are used in dogs compared to wild
animals. Regulatory and procedural adaptations are essential to address these barriers and enhance ORV safety for domestic
dogs. Recommendations include encouraging manufacturers to secure central licensure for ORV use in dogs, and for the World
Organisation for Animal Health (WOAH) to support regulatory convergence among member countries. Additionally, WOAH
and the United Against Rabies initiative should adopt a structured, prequalification process to validate ORVs specifically for
canine use, thereby enhancing global oversight and harmonizing standards. Establishing a global regulatory science agenda,
spearheaded by the WOAH and WHO, could further advance ORV deployment, facilitating a standardized and safe application
of ORVs in canine rabies control efforts.
Title: Comparative Evaluation of Herbal Growth Promoter (Auctus) and Antibiotic Growth Promoter (Enramycin) in Broiler Chickens
Abstract :
Abstract :
The present study aimed to evaluate the efficacy of a herbal growth promoter (Auctus) as an alternative to an antibiotic growth
promoter (AGP) in broilers. A total of 180 one-day-old VenCobb 430 Y chicks were randomly assigned to three groups: T0
(basal diet), T1 (basal diet + 100 g/MT Enramycin), and T2 (basal diet + 500 g/MT Auctus), with four replicates per group.
The trial duration was over 42 days. Results showed a significant improvement (P≤0.05) in body weight, FCR, and European
Production Efficiency Factor (EPEF) in both T1 and T2 groups compared to the control. Histomorphometry analysis revealed
significantly higher (P<0.05) villus height in the duodenum, jejunum, and ileum in the T2 group. The cecal microbial analysis
indicated a significant reduction in E. coli counts in T2 group and an increase (P<0.001) in Lactobacilli in the T1 and T2 groups.
Immune response analysis showed a significantly higher (P<0.001) antibody titer against Newcastle disease virus in the T1 and
T2 groups. Furthermore, there was a significant (P<0.05) increase in the bursa weight of broilers in the T2 group compared to
the control group. Herbal growth promoter fed broilers (T2) showed comparable growth performance and immune responses to
AGP fed broilers (T1) but had lower E. coli levels in the gut and longer small intestine villi. These findings suggest that Auctus
can effectively replace AGPs, supporting broiler performance while addressing concerns related to antibiotic use and human
health.
Title: Differential Expression of Transforming Growth Factor Beta Receptor 3 and Ubiquitin-protein Ligase E3C in LWY and Ankamali Pigs in Kerala
Abstract :
Abstract :
Present study investigates the differential expression of Transforming Growth Factor Beta Receptor 3 (TGFBR3) and Ubiquitin-
Protein Ligase E3C (UBE3C) genes in Large White Yorkshire (LWY) and Ankamali pigs, two distinct genetic groups in Kerala.
TGFBR3, a key regulator of the TGF-β signalling 1 pathway, influences muscle growth, fibrosis, and fat deposition, impacting
meat quality. UBE3C, a component of the ubiquitin-proteasome system (UPS), plays a crucial role in protein turnover and lipid
metabolism, affecting muscle composition. Using quantitative real-time PCR (qRT-PCR), gene expression was analysed in
skeletal muscle tissues from six pigs per genetic group. Results revealed a significant down regulation of TGFBR3 and UBE3C
in Ankamali pigs, suggesting reduced TGF-β pathway activity and proteasomal function. These differences may contribute to
lower fat deposition and higher lean meat yield in Ankamali pigs, while LWY pigs exhibit higher intramuscular fat and superior
growth rates. Present findings highlighted TGFBR3 and UBE3C as potential genetic markers for optimising growth performance
and meat quality.
Title: Effect of Exposure to Slaughter Ambient on Behavioral and
Carcass Parameters in Goats
Abstract :
Abstract :
The present study was undertaken to assess the effect of exposure to slaughter ambient on various behavioural and carcass
parameters in goats. A total of 18 bucks (Boer cross, 8-12 months of age, 24-28 kg live weight) were divided into 3 groups
(n=6) viz., C- goats slaughtered alone, E - goats exposed to slaughter ambient by witnessing the slaughter of goat from S group,
S- goats slaughtered in front of E groups. The goats were Halal slaughtered, and various behavioural parameters (vocalization,
escape behaviour, turning backwards, and urination), blood loss, time to death, and carcass shrinkage were assessed. The
exposure to slaughter ambient in goats affected the behavioural responses, with medium-grade responses for vocalization and
avoidance behaviour in 50% of goats. The exposure to slaughter ambient in goats did not significantly affect the time to death,
bleed-out percentage, and carcass shrinkage percentage. Thus, the present study highlighted the issue of animal welfare and
emotional stress induced by exposure to slaughter ambient in goats as indicated by behavioural responses.
Title: Determination of Virulence Factors and Antibiotic Resistance with Special Emphasis on Extended Spectrum β Lactamase Producing Escherichia coli from Sheep and Goats in Jammu, India
Abstract :
Abstract :
The present study was aimed at investigating the pathogenic strains of Escherichia coli in sheep and goats and their antibiotic
resistance patterns with special emphasis on extended spectrum beta lactamases producing E. coli. A total of 200 presumptive
E. coli isolates were obtained from 120 faecal samples of sheep and goats. Out of these 200 isolates, 62 isolates showed the
presence of at least one virulence gene studied. Among these, 10 isolates carried eaeA gene either alone or in combination
with ehxA and were categorized as EPEC. 44 isolates carried stx genes and were categorized as STEC, 08 isolates carried ehxA
genes and were designated as EHEC. All 62 isolates showing the presence of at least one virulence gene were further screened
for ESBL production by using primers specific for blaTEM, blaCTX-M, blaSHV and blaOXA genes. Out of 62 isolates, only 22 were
tested positive for presence of ESBL genes. Further, the prevalence of blaTEM, blaCTX-M and blaSHV genes was found to be 54.54%,
27.27% and 36.36% respectively. Antibiotic sensitivity profiling of the isolates positive for virulence genes revealed that all
isolates were resistant to cefotaxime.
