The experiment was conducted to study the efficacy of different types of litter amendments on litter quality and broiler performance during winter (December–January). A total number of 180, day-old (Vencobb) broiler chicks were randomly assigned to three equal groups. One bearing control group and other two comprise litter amendments with alum (ATL) and sodium bisulphate (SBTL) treatment groups, each having 60 birds in three replications of 20 numbers for 6 weeks. The findings of the study revealed significant variation (p < .05) in the moisture content and pH of the control and treated litter. This clearly indicates the efficiency of litter treatment products improving the quality of litter thus in turn the ambient environment for the bird. The average body weight was significantly highest (p < .05) in the SBTL group (1912 g) followed closely by the ATL group (1865 g) in comparison to the control group (1822 g) at the end of sixth week. The growing chicks gained significantly (p < .05) more body weight with better FCR, PER, EER and survivability in respective order of succession. The overall hygiene of the broiler chicks was better with less cake formation and without any foot pad dermatitis or breast blister lesion in the treatment groups. Thus it can be concluded that litter amendment with alum (ATL) and sodium bisulphate (SBTL) treatment had significant influence on quality of litter and in turn improved the performances of broiler chicks without any adverse effect. © 2016 The Author(s).

Azadirachta indica, is locally called as "Neem" belongs to the family Meliaceae. "Neem" is a medicinal herb traditionally used for the treatment of Diabetes, leprosy and Respiratory diseases. The present study was carried out to identify the phytocomponents present in the methanolic extract of the leaves of Azadirachta indica by GC-MS analysis. From the GC-MS results five compounds were identified as major constituents, they are Phytol, Linolenic acid, Homo-γ-linolenic acid, Palmitic acid and Tridecylic acid. Source

Classical swine fever (CSF) is one of the most devastating epizootic diseases of pigs, causing high morbidity and mortality worldwide. The diversity of clinical signs and similarity in disease manifestations to other diseases make CSF difficult to diagnose with certainty. The disease is further complicated by the presence of a number of different strains belonging to three phylogenetic groups. Advanced diagnostic techniques allow detection of antigens or antibodies in clinical samples, leading to implementation of proper and effective control programs. Polymerase chain reaction (PCR)-based methods, including portable real-time PCR, provide diagnosis in a few hours with precision and accuracy, even at the point of care. The disease is controlled by following a stamping out policy in countries where vaccination is not practiced, whereas immunization with live attenuated vaccines containing the 'C' strain is effectively used to control the disease in endemic countries. To overcome the problem of differentiation of infected from vaccinated animals, different types of marker vaccines, with variable degrees of efficacy, along with companion diagnostic assays have been developed and may be useful in controlling and even eradicating the disease in the foreseeable future. The present review aims to provide an overview and status of CSF as a whole with special reference to swine husbandry in India. Copyright © Cambridge University Press 2014. Source

Objective: The aim of the present study was to isolate and identify Aeromonas (A.) species and assess their toxin producing ability in foods of animal origin from North East India. Materials and Methods: A total of 332 animal food samples (fish, poultry meat, pork and chevon) of which 38 (11.44%) isolates were identified by the 16S rRNA technique were included in the study. The enterotoxigenicity of the isolates was measured by the Mouse Paw Oedema Test (MPOT), rabbit ileal loop (RIL) and vascular permeability reaction (VPR) test. Results: Maximum positivity was shown by the samples from fish (13.13%), followed by poultry meat (11.5%), pork (9.85%) and chevon (2.5%). A. hydrophila was the predominant species (92.10%) followed by A. sobria (5.26%) and A. caviae (2.63%). Conclusions: All the Aeromonas strains isolated by culture methods expressed enterotoxigenicity by MPOT, RIL assay and VPR test. Source

The study was conducted to identify SNPs of quantitative trait loci (QTL) associated with susceptibility to Mycobacterium avium ssp. paratuberculosis (MAP) infection in cattle. Total 20 SNPs from the cattle QTL database were selected on the basis of the potential role in Mycobacterium susceptibility and a case: control association study was conducted in cattle. Out of 20 SNPs total 17 SNPs were polymorphic and 3 were monomorphic in population. The SNP (rs41945014) was significantly associated with MAP and revealed that ODDs of GG and GT genotypes verses TT genotype were 1.22 (0.33-4.49; 95% CI) and 3.37 (1.23-9.23; 95% CI), respectively. The proportion of GG and GT genotypes were significantly higher in bovine paratuberculosis positive animals suggested that selection against these 2 genotypes may confer resistance against bovine paratuberculosis. The all other 16 polymorphic SNPs of the present investigation were not differing significantly in case-control animals. Source
