this study was designed to investigate the effects of different levels of tarragon powder on general performance and anetometric, properties of digestive system of male broiler chickens. 200 one-day-old ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. experimental diets were set on the bas...

this study was designed to investigate the effects of different levels of tarragon powder on performance and carcass’ characteristics of broiler chickens. 200 one-day-old ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. experimental diets were set on the basis of corn-soy-wheat and ross 30...

Emerging evidence suggests a potential role of stearoyl-CoA desaturase (SCD)-1 in the control of body weight and energy homeostasis. The present study was conducted to investigate the effects of several energy balance-related factors (leptin, cerulenin, food deprivation, genotype, and gender) on SCD gene expression in chickens. In experiment 1, 6-week-old female and male broiler chickens were u...

The effects of selected herbal dietary supplements on the growth performance and carcass quality of broiler chicken were investigated. Three hundred and eight day-old, male broiler chicks of Indian River strain were randomly allotted to seven experimental diets namely negative control, 0.0125% flavomycin (positive control), 0.1% Moringa leaf powder (MLP), 0.05% Moringa leaf powder, 0.035% Zigbi...

The purpose of this study was to investigate the biological and genetic characterization of persistent Salmonella isolates in an integrated broiler chicken operation, in an attempt to elucidate the source of contamination. From the breeder farm, the hatchery, the broiler farm and the chicken slaughter house of an integrated broiler chicken operation, a total of 6 serotypes were observed. Althou...

Recent studies have suggested the utilization of maggots as a feed supplement forenhanced broiler performance. Maggots, which are a major dietary source of protein, appear during the biodegradation of chicken droppings using house flies. The objective ofthe present study was to investigate the effect of maggot supplementation on the meat quality and growth performance of broiler chickens. A tot...

A lower price on poultry meat, compared with other meats (beef, pork etc.), affects the increasing demand for poultry meat. The productivity and production cost of broiler chickens are directly related to the amount of feed fed, the proportion of crude protein in the feed, and the biological value and price of the feed. The EU produces only 30% of the protein crops used for feed; thus, the larg...

We examined 29 isolates of Salmonella enterica subspecies enterica serovar Schwarzengrund from broiler chickens (n=19) and retail chicken meats (n=10) in Japan for antimicrobial susceptibility and pulsed-field gel electrophoresis (PFGE) profiling. All isolates exhibited resistance to both bicozamycin and sulfadimethoxine (minimum inhibitory concentration of both antimicrobial agents: >512 micro...

A cross-sectional study was performed to estimate the prevalence of Salmonella on retail market chicken carcasses in Colombia. A total of 1,003 broiler chicken carcasses from 23 departments (one city per department) were collected via a stratified sampling method. Carcass rinses were tested for the presence of Salmonella by conventional culture methods. Salmonella strains were isolated from 27...

The effect of ochratoxin A (OA) on the body weight, feed intake, and feed conversion was investigated in broiler chicken fed dietary levels of OA at 0, 1, and 2 ppm for 28 days from hatch. Feeding OA significantly reduced the growth rate of broiler chicken. The reduction was observed from the first week onwards in OA-treated groups. Feed consumption and feed conversion also showed a diminishing...
