the effect of dose and regimen of organic acids on micro-flora and morphology of small intestine were studied in a total of 300 male day old broiler chicks using completely randomized design. salkil had no significant effects on the number of villi per view field and percent of convoluted villi. salkil had a significant effect on the number of tongue, ridge shaped (p

this study was conducted to evaluate the effects of different dietary levels of full fat safflower seed (0, 5, 10, 15 and 20% of diet) on performance, carcass characteristics and selected blood metabolites of broiler chickens from arbor acres plus strain. the experiment was designed with 350 commercial one-day-old male broiler chickens using completely randomized design with 5 dietary treatment...

Objective: The aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (CGM) and its effect on growth performance of broiler chicks. Methods: Chemical composition and nitrogen corrected true metabolizable energy of CGM was determined by standard and precision-fed cockerel assay methods.  For evaluating of protein quality, 90 male broiler chicks in a com...

The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...

this study was conducted to compare susceptibility of six different strains of male broilers to ascites syndrome. in this experiment, 612 one-day-old male broiler chicks from five international hybrids (e.g, arbor acres, cobb 500, hubbard, lohmann, and ross 508) and an iranian hybrid (arian) were used. growth performance, ascites mortality ratio, the ratio of right ventricle to total ventricles...

Lysine (Lys) and Methionine (Met) as two primary essential amino acids and precursors of carnitine biosynthesis are involved in most of economical traits function in domestic animals. We assessed the impact of dietary Lys and Met on the performance, lipid redistribution, intramuscular fat, carcass quality and especially phenotypic correlations among some studied parameters in broiler chickens. ...

This study evaluated the behavior of broiler chickens subjected to thermal stress during different periods day and age birds. A total 180 one-day-old male chicks were allocated three chambers. Each chamber contained five boxes, with 12 chicks/box. Birds assigned a completely randomized design. The birds filmed, images recorded every minute two periods: morning (from 08:00 09:00 h) afternoon 17:...
