The genetic diversity of Campylobacter jejuni and Campylobacter coliisolates from commercial broiler farms was examined by multilocus sequence typing (MLST), with an assessment of the impact of the sample type and laboratory method on the genotypes of Campylobacter isolated. A total of 645C. jejuniand 106C. coli isolates were obtained from 32 flocks and 17 farms, with 47 sequence types (STs) id...

High temperature is one of the key environmental stressors affecting broiler production efficiency and meat yield. Knowledge of broiler self-regulation mechanisms under heat stress is important for the modern scale of poultry breeding. In the present study, the SWATH strategy was employed to investigate the temporal response of the broiler liver to heat stress. A total of 4,271 proteins were id...

In an attempt to determine the seroprevalence of avian leukosis virus (ALV) in exotic broiler chickens and Nigerian local chickens in Zaria, Nigeria, a total of 600 sera (300 from exotic broiler chickens and 300 from Nigerian local chickens), obtained from the live bird market in Zaria, Nigeria, were tested for ALV p27 antigen by the antigen capture enzyme linked immunosorbent assay (ac-ELISA) ...

This experiment was conducted to investigate the effects of olive leaf (OL) on immune response and some blood metabolites of broiler chickens. A total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. Birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% OL powder from 14 to 4...

the aim of this experiment was to study the effects of hydrochloric and butyric acids addition to broiler diets on performance, carcass characteristics, intestinal microbial population and intestinal histology. two hundred eighty ross 308 one-day old female broiler chicks were assigned to 7 dietary treatments and 4 replicates of 10 chicks in a completely randomized design. experimental treatmen...

the objectives of this study were to determinethe interactions between two hepatic enzymes and some minerals in the liver of broiler chickens. the study was performed with male and female from 1 to 56 days of age of broiler chickens. malic acid was added to the water and offered to chickens freely from the start to the end of the experiment with constant concentration. the treatments consisted ...
