One of the major concerns in poultry production presents heat stress (HS) and it is followed by significant economic loss manifested by reduced growth, decreased immune response, increased mortality, etc. The objective of this study was to investigate whether the early-age thermal conditioning (ETC) and vitamin C (Vit.C) treatments, individually and in combination, produce their beneficial effects through increased heat release manifested as a change in respiration rate consequentially leading to a decrease in the chicken's body temperature and thus reduce the harmful effects of HS. A 400 broiler chicks mixed sex male and female were split into four groups. …

Turkish Journal of Veterinary & Animal Sciences
A study was conducted to evaluate the changes in serum biochemical and lipid profile, and fatty acid composition of breast meat of broiler chickens fed supplemental grape seed extract (GSE). A total of 240 1-day-old male broiler chickens were randomly allocated to 4 groups, each consisting of 4 replicate pens having 15 birds/replicate pen. One group served as control group fed basal diets and other groups received 100, 200, and 400 ppm GSE supplemented to the basal diets. Liver weight was greater in broilers fed 200 ppm GSE compared to the other groups (P = 0.004, L = 0.024, C …

Competitive exclusion (CE) relies on the activity of normal flora to limit intestinal colonization by enteric pathogens. This study aims to investigate the effects of CEon Salmonellainfectionin broilers. The protective effect of CE on Salmonella cecal colonization was evaluated in 1 day-old chicks.In the laboratory trial, CE products were administered by oral inoculation, drinking water and whole body spray. Three days after treatment,the chickens were challenged with 107cfu/mL of SalmonellaEnteritidisorally, and were evaluated for 10 days. The CE-treated chickens showed comparable protection andthe number of Salmonella in the cecal contents significantly decreased(P<0.05)compared with those of the positive control. In the farm trial,CE was administeredby whole body spray at the hatchery and the second was administered by drinking water and evaluated at 32 and 42 days, respectively. The CE significantly reduced Salmonellacontamination in the farm trial andno Salmonellawas detected in the cecal contents compared with the control group. Average body weight gains, feed conversion ratioand theperformance indexof the chickens were greater than thecontrol group. Thus, the use of CEhad a positive effect on broiler performance. Furthermore, the CE-treated chickens displayed greater intestinal histology including villous height, submuscular layerand cell mitosis.These studies demonstrate that CEwas able to protect chickens from Salmonella cecalcolonization and it is apparent that new methodologies associated with the development of a workable CE program are needed in thepoultry industry.

The present study was conducted to investigate the effects of three biotechnological products of Saccharomyces cerevisiae (organic selenium, concentrated mannan of S. cerevisiae, and living cells of the same yeast) used in broiler diet on growth performance, health status, and meat quality and composition. One hundred day-old broiler chickens were divided into four groups (control and three experimental groups using the above-mentioned diet supplements) and fed basic feed mixture (developed by the Nutrition Department at the University of Agricultural Sciences and Veterinary Medicine in Cluj-Napoca, Romania) for 42 days. After this period, from each group, five birds were sacrificed and …

The aim of this study was to investigate the effects of the supplementation of different concentrations of rosemary in broiler diets from day 1 to 42 on growth performance, carcass quality, and cecal microbiological composition of chickens. The research was carried out with 1200 Ross 308 chickens, divided into 4 groups with 6 repetitions per group. The treatment groups were: control group (C) without rosemary, 0.2% rosemary group (0.2R), 0.4% rosemary group (0.4R), and 0.6% rosemary group (0.6R). Production parameters and the European Production Efficiency Factor (EPEF) were determined. At the end of the trial 12 chicks per group were …

Turkish Journal of Veterinary & Animal Sciences
The efficacy of diets containing 40%-50% wheat, barley, or oat grains, fermented by a solid-state fermentation process, on bird performance, carcass yield, digestive organ development, and intestinal viscosity was tested. Compared with broiler chicks fed unfermented grains, those fed fermented oats had increased feed intake, and treatment with fermented wheat and barley improved the feed conversion ratio at days 21 and 42. Treatment with fermented barley and oats resulted in increased body weight at day 42. Treatment with fermented wheat and oats increased the percentage of carcass yield. Birds fed unfermented grains had highly viscous digesta, not seen among birds …

The Effects Of Dietary Glutamine Supplementation On Growth Performance And Intestinal Morphology Of Broiler Chickens Reared Under Hot Conditions, Farhad Jazideh, Parviz Farhoomand, Mohsen Daneshyar, Gholamreza Najafi
Turkish Journal of Veterinary & Animal Sciences
Dietary supplementation effects of 0%, 0.25%, 0.5%, and 1% glutamine were investigated on the performance and development of the gastrointestinal tract in broilers reared under hot conditions. No significant differences were observed between the treatments for feed intake and feed conversion ratio during the starter period, grower period, or entire experiment (P > 0.05). During the grower period, only 0.5% glutamine-fed birds had higher body weight gain than others (P < 0.05). For the entire period, body weight gain of 0.5% glutamine-fed birds was greater than that of 0.00% and 0.25% glutamine-fed ones (P < 0.05). Furthermore, 0.5% glutamine-fed birds showed longer villus height than other birds (P < 0.05). In the jejunum, both 0.5% and 1% glutamine consumption caused longer villus height as compared to 0.00% and 0.25% glutamine (P < 0.05). Villus height of 0.25% glutamine-fed birds was higher than that of 0.00% glutamine-fed ones (P < 0.05). None of the ileum morphological parameters were affected by glutamine supplementation (P > 0.05). In conclusion, supplementation of 0.5% glutamine improved the intestinal morphology and body weight gain of broilers under heat stress. Higher dietary glutamine (1%) increased the villus height in the jejunum …
