This study was conducted to validate echocardiography in chickens, and to compare cardiac structure and function between broiler and Leghorn chickens. Diameters of the right and left ventricles, and thicknesses of the left ventricular free wall and the interventricular septum were measured echocardiographically in 5- and 7-wk-old chickens from both lines. Images were obtained from minimally res...

An experimental study was carried over a period of 42 days using 160 day-old commercial broiler chicks (Ven Cobb) to study the effect of copper and flavomycin as feed additives on growth performance in broiler chicken. The birds were divided into four groups with four replicates of ten chicks in each replicate. The treatment (T1) was control with standard broiler ration and Cu as CuSO4 at 100 p...

An attempt was made to standardize an in-house immuno-enzyme assay for measuring antibodies of infectious bursal disease virus (IBDV) in chicken. The test was performed after coating plates with ELISA antigens prepared by two methods. Antigen “A” was prepared from infectious bursal disease virus infected chicken embryo fibroblasts culture by concentration with dialysis against PEG-6000 while an...

A molecular study of intestinal samples from 21 broiler flocks with a history of enteritis revealed that 23.8% and 14.3% were positive for chicken astrovirus (CAstV) and avian rotavirus (ARV), respectively. CAstV and group A ARV were simultaneously detected in only one broiler flock. Birds in this group developed the significant intestinal lesions characterized by frothy contents, paleness, and...

Crowing-type chicken is one of the important chicken breeds in Indonesia. This study was conducted to investigate the crowing characters of Pelung chicken and the effect of exon 7 FoxP2 gene polymorphism in mute chicken. Chicken were obtained from local breeder. Pelung chicken crowing and morphology characterizations were conducted in Cianjur, West Java, Indonesia. Chicken breeding (♀ ...

the aim of this study was to determine feasibility of gamma irradiation in broiler chicks’ diet and scrutiny of productive performance of broiler due to gamma irradiated diets. there were 256 broiler chicks (male and female) from arian strain. experiment was statistically analyzed using balanced complete randomized design with four factors (including four irradiation doses: 0, 6.7, 7.7 and 8.7 ...

This study aimed to investigate gene expression in the chicken liver for lean and fat broiler lines. Birds used in this study were 2 and 4 weeks of age; they were derived from the 14th generation of Northeast Agricultural University broiler lines, which were divergently selected based on abdominal fat content. Chicken Genome Arrays were used to screen differentially expressed genes in the liver...

Three hundred and sixty one-day-old chicks (Arian) were used in a completely randomized design with five treatments and four replicates for each treatment. The experimental treatments included: control group (without barley) with and without enzyme, 20% hulled barley with and without enzyme, 20% hull-less barley with and without enzyme. Body weights, feed intake and feed conversion were determi...

Aim: This study was aimed to develop the disease resistance broiler chicken lines over two generations (G , G and G ) of 0 1 2 selection for immunocompetence (IC) index by targeting all the facets of immune response traits viz., humoral response (HR) to Sheep red blood cells (SRBC), cell mediated immune response (CMI) to phytohaeagglutinationP mitogen (PHA-P), levels of serum serum immunoglobin...
