The aim of this study was to investigate the presence of antibodies to ALV-J in broilers and broiler breeders. For this, 5 broiler units and 1 broiler breeding unit in the Marmara region were visited. Seventy 4-6 -week-old chicks from the broiler units, consisting of 14 chicks from each broiler unit, were selected. Seventeen chickens from the broiler breeding unit were also selected. The chicks...

Responses to stunting syndrome (SS) infective material obtained from affected broilers and administered per os were monitored for 3 wk in a fast-growing commercial broiler population, in slow-growing Leghorn chicks, and in turkey poults. At 2 and 3 wk, the size of the gastrointestinal tract (GIT) segments, the pH of the GIT contents, and the activities of digestive enzymes in the intestinal con...

Using distillers dried grains with solubles (DDGS) as a feed ingredient in poultry nutrition has lately been increased. This study was conducted to evaluate the effect of adding different dietary levels of DDGS on the productive performance of broiler chicks from 1 to 35 d of age. Two hundred forty one-d-old broiler chicks were randomly distributed among 3 treatment groups with eight replicates...

Three-week-old broiler chicks and 1-yr-old Leghorn cocks were used to determine the effect of beta-glucanase addition (experimental product from Trichoderma longibrachiatum) to a 60% barley-based diet on rate of feed passage, transit time, and mean retention time. Fecal chromium oxide content was used to calculate cumulated and noncumulated excretion data. A Hill equation was chosen to test the...

An experiment was conducted to determine the digestible amino acids requirements of broilers based on different ideal amino acid ratios for male and female broiler chicks during finisher period. Experimental period began at day 29 and lasted in 42 d of age. A total of 720 male and female broiler chicks were equally distributed to 12 dietary treatments with 15 birds per pen and 4 pens per treatm...

The embryonic modal value of heart rate (MHR) differs between broiler and White Leghorn chickens, but the initial development of cholinergic chronotropic control of embryonic heart rate (HR) does not. Thus, we hypothesized that hatchling MHR should also differ between broiler and White Leghorn strains, while the development of a physiological regulation, such as the endothermic HR response, sho...

The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal viscosity, digestive enzyme activities and ileal nutrient digestibility in different ages of poultry. In Experiments 1 and 2, 1-d-old broiler chicks and 1-y-old ...

A total of 210 twenty twoday-old broiler chicks were used in this programme to investigale the performance, [ca\ intake, digestibility and visceral organ mass of broiler chicks fed with high level of olive pulp.supplemented with two antibiotics: streptomycin and tylosin. The two antibiotics were added to supply 150 nig/kg of the active ingredient. Chicks which consumed the medicated diets had m...

OBJECTIVE The objective of the present study was to determine whether mango saponin (MS) could be used as a feed additive in broiler chicks by evaluating growth performance, carcass characteristics, meat quality, and plasma biochemical indices. METHODS A total of 216 1-d-old Arbor Acres male broiler chicks were randomly assigned into three dietary treatments supplemented with 0 (control), 0.1...

While characterizing the intestinal bacterial community of broiler chickens, we detected epsilon-proteobacterial DNA in the ilea of 3-day-old commercial broiler chicks (J. Lu, U. Idris, B. Harmon, C. Hofacre, J. J. Maurer, and M. D. Lee, Appl. Environ. Microbiol. 69:6816-6824, 2003). The sequences exhibited high levels of similarity to Campylobacter jejuni and Campylobacter coli sequences, sugg...
