Efficacy of Fermentation Product and Probiotic Supplementation on Growth Performance, Gut Microflora and Immunity of Broiler Chickens.

Concern for global health security and the environment due to the emergence of antibiotic-resistant bacteria and antibiotic residues in meat and other livestock products has led many countries to restrict the use of antibiotics in animal feed. This experiment was performed to assess the impact of dietary supplementation of a probiotic () and a postbiotic ( fermentation product) on growth performance, carcass traits, blood haemato-biochemical profile, gut microflora, gut morphology, and immune response in broilers as an alternative to antimicrobials in poultry production system to minimize the effect on global health security. A total of 324 one-day-old Ven Cobb 400 broiler chicks were randomly divided into three dietary groups, each containing 12 replicated pens, and each replicate contained nine chickens.

Molecular characterization of (Myxosporea: Myxobolidae) infecting the gill lamellae of carp (Hamilton).

The present study attempted sequencing the 18S rRNA gene of infecting the gill lamellae of carp, and compared its genetic homology and phylogenetic characteristics with 18S rRNA genes of other spp. The infected fish had up to 3 small, creamy white plasmodia per gill filament with 30-50 spores each. The spore size was 17.

Molecular characterization of and (Crustacea: Argulidae) infecting the cultured carps in West Bengal, India using 18S rRNA gene sequences.

The present study characterized spp. infecting the cultured carps using 18S rRNA gene sequences, estimated the genetic similarity among spp. and established their phylogenetic relationship.

The phylogenetic position of (Myxozoa, Myxosporea, Bivalvulida) infecting gill lamellae of (Hamilton, 1822) based on 18S rRNA sequence analysis.

Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species.

Serotyping, pathogenicity and antibiogram of Escherichia coli isolated from raw poultry meat in West Bengal, India.

This study has been undertaken to isolate and characterise Escherichia coli strains from raw poultry meat in West Bengal, determine their pathogenicity and identify the prevalent serotypes and their antibiogram. A total of 83 raw poultry meat samples were collected from February to July 2004. Thirty-three samples (39.

Detection of picobirnavirus and rotavirus in diarrhoeic faecal samples of cattle and buffalo calves in Mumbai metropolis, Western India.

In this study 113 diarrhoeic faecal samples obtained from buffalo (n = 68) and cattle (n = 45) calves under 1 years of age were analysed in order to determine the presence of rotavirus infection and the frequency of picobirnavirus excretion. Eleven (9.73%) samples positive for group A rotavirus were identified through RNA-polyacrylamide gel electrophoresis (RNA-PAGE), while 4 (3.

Determination of bovine rotavirus G serotype by polymerase chain reaction.

A total of 113 diarrheic samples comprising of 68 buffalo calves and 45 cow calves were screened by RNA-PAGE for the detection of presence of rotavirus. RNA-PAGE analysis of these samples revealed 11 (9.73%) was found positive for rotavirus.
