The effects of dietary saturated fatty acids and polyunsaturated fatty acids (PUFA) of the n-3 and n-6 series on weight gain, body composition and substrate oxidation were investigated in broiler chickens. At 3 weeks of age three groups of chickens (n 30; ten birds per group) were fed the fat-enriched experimental diets for 5 weeks. These diets were isonitrogenous, isoenergetic and contained 20...

Abstract Background The study examined the effects of dietary supplementation Syzygium aromaticum leaf meal (SLM) on haematology, serum biochemistry and antioxidative status laying hens. Results A total 150 20-week-old Isa brown birds were randomly assigned to three experimental diets: Diet 1/control (no supplementation), 2 (0.25% SLM) 3 (0.50% SLM). Each diet was further divided into five (5) ...

the aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. in this study, 450 day-old female broiler chickens (arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. on day 14 of the experiment,...

An experiment was conducted to study the effect of supplementing Non-starch Polysaccharide enzymes and prebiotics alone or in combination to sub-optimal energy corn soybeanbased broiler diets on performance. 150 day old broiler chicks were randomly distributed in to five experimental groups, six replicates per group and five birds per replicate. A standard diet (SD) and a basal diet (BD) (225 k...

For this purpose, a total 180 six-day-old quail chicks were randomly assigned into five different treatment groups, each with three replicates (12 birds per replicate). The was conducted for 35 days. Different groups quails...

Little is known about how hormones interact in the photoperiodic induction of seasonal responses in birds. In this study, two experiments determined if the treatment with melatonin altered inhibitory effects of prolactin on photoperiodic induction of seasonal responses in the Palearctic-Indian migratory male redheaded bunting Emberiza bruniceps. Each experiment employed three groups (N = 6-7 ea...

The objective of the present study was to investigate the effect of raw and differently processed [aqueous heating, dehulled, and dry heating (toasted)] kidney bean meals on the performance, weights, and histology of internal organs of broiler chicken. The feeding trial lasted for 56 d. Two hundred twenty-five 1-d-old broiler chicks (Anak strain) were used for the study. There were 5 treatment ...
