The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (contr...

The aim of the study was to determine the effect of yeast probiotic on body weight, and the activities of anti-oxidant enzymes: superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), and malondialdehyde (MDA) concentration of broiler chickens. The experiment was carried out on hybrid Hubbard broiler chickens (n = 200). Two-hundred day-old chicks were randomly selected and ...

This experiment was conducted to investigate the effect of different levels of dietary chromium yeast (Cr-yeast) on thigh meat quality of broiler chicks reared under heat stress condition. Two hundred and forty Ross male chickens in heat stress condition (33±3°C) were allocated to five treatments in a completely randomized design. Treatments were supplemented with 0 (control), 200, 400, 800 and...

The present experiment investigated the effects of conjugated linoleic acid (CLA) on the growth performance, oocyst shedding, duodenal mucosal immune response, and redox status of broiler chicks infected with Eimeria acervulina. Totally 144 birds were fed either the basal diet or 1.5% CLA diet for 21 days, and then half of them from each dietary treatment were inoculated with 10 000 Eimeria ace...

Broiler flocks often become infected with Campylobacter and Salmonella, and the exact contamination routes are still not fully understood. Insects like darkling beetles and their larvae may play a role in transfer of the pathogens between consecutive cycles. In this study, several groups of beetles and their larvae were artificially contaminated with a mixture of Salmonella enterica serovar Par...

Two Hundred and six day old Fulani Ecotype chicks (FEC)were used to investigate the effect of feeding two types diet (Chick starter Broiler formulated meet standard nutritional requirement pullets broiler chicks) on growth traits performance from O 8 weeks. The contained 23% Crude Protein (CP) 3000Kcal/kg Metabolizable Energy (ME), Chick 21% CP 2800Kcal/Kg ME. measured were body weight (BW), le...

AIM An experimental study was conducted on 192-day-old broiler chicks for evaluating the effect of 10% neem leaf extract (NLE) supplementationon biochemical parameters in chickens experimentally infected with Escherichia coli O78 at 10(7) CFU/0.5 ml at 7 days of age. MATERIALS AND METHODS The 192-day-old broiler chicks were procured. These chicks were divided into two groups (A and B) contain...

Organic acids can be replaced as effective feed additives with antibiotics. Organic acids and their salts have the potential to retard the development of pathogens in the diets and thus maintain the microbial equilibrium in the gastrointestinal tract. In this study, 225 day-old broiler chicks were used for a period of 21 days in order to examine the effect of different levels of organic acids (...

This study was conducted to evaluate the effects of dietary inclusion of thyme essential oil (TEO) on growth performance and immune responses of broiler chicks subjected to heat stress (HS). Broilers were divided into five groups; group 1) chicks fed with basal diet and reared under thermoneutral condition; group 2) chicks fed with basal diet and subjected to HS condition; and groups 3, 4 and 5...

The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...
