this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
This research was conducted to investigate the effect of different levels of metabolisable energy and crude protein on performance, carcass characteristics and blood parameters of Japanese quail during grower phase (14-28 d of age). Nine hundreds 14-d-old male birds were used to examine 3 levels of energy (2900, 3050 and 3200 Kcal of ME/Kg of the diet) and 3 levels of protein (21.6, 24 and 26.4...
________________________________________________________________________________ Abstract Feed efficiency is of major economic importance in beef production. The objective of this work was to evaluate alternative measures of feed efficiency for use in genetic evaluation. To meet this objective, genetic parameters were estimated for the components of efficiency. These parameters were then used i...
Problem statement: Endogenous enzymes of broilers cannot adequately digest nonstarch polysaccharides and subsequently the ingestion of high levels of soluble NSP leads to increased digesta viscosity and reduced nutrient digestibility and absorption. Supplementation of NSPs degrading enzymes may remove the anti nutritive effects of NSPs and release some nutrients (starch, protein) from these ele...
The effect of dietary protein level and feed restriction on performance, body temperature and hematological values was evaluated, using Ross 308 broiler chicks under heat stress. For this purpose, three dietary treatments were fed to broilers during 21 to 42 days of age. Two treatments consisted of diets with protein levels recommended by NRC, 1994 and 85% of NRC recommendation and were fed ad-...

The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
To evaluate the effects of garlic on some blood metabolites in pre-partum dairy goats, the ration was supplemented with raw garlic at the doses of 0, 30, 50 and 70 g kg-1 of Dry matter (DM) in eight pregnant Mahabadi breed goats (59 ± 1 kg initial live weight) in a replicated Latin square design during the last two months of pregnancy. Each experimental period lasted 14 days with the first 12 d...
this investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of rhode island red (rir) chicken taking single hatched out pedigreed 100 chicks at central avian research institute, izatnagar, india. data was analyzed by least squares analysis of variance. least squares means of chick weight (cw), body weight (bw), shank length (sl), keel length (kl...
the effect of ginger powder on performance, carcass characteristics and blood parameters of broilers
to study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). all treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called t1, 2t, t3 and t4 that were ad...
