This experiment was conducted to study the effects of two kinds of sodium and calcium bentonite (NaB and CaB) on performance, blood biochemical parameters, carcass characteristics and tibia ash of broiler chickens. Two hundred and sixty day old broilers of male Ross 308 strain were allocated to 5 treatments with four replicatates and 13 broilers in each. The experiment was carried out in a comp...

This experiment was undertaken to evaluate the effect of dietary level of artichoke (Cynara scolymus) on growth performance and immune response of broilers under heat stress (HS). Two hundred forty day-old broiler chicks (Ross, 308) were randomly assigned to one of four dietary treatments with four replicate pens per treatment (15 birds per pen) in a completely randomized design with a 2 × 4 fa...

A study was conducted to evaluate efficacyof wheat based vs. corn based diets on growth performance, carcass traits,blood parameters, jejunum morphological development, immunity, cecal microflora and excreta moisture in broiler chicks fed according to digestible essential amino acid profile. One hundred forty day old Ross 308 male broiler chicks randomly distributed into ten separated floor pen...

The objective of this study was to investigate development of the weight and the morphological development of the rectum in broiler chickens. Twenty broiler chickens (Ross 308) were used in this experiment and they were 12, 20, 35 and 44 days of age. Samples from the rectum of chicks were sectioned in an unbiased manner and examined quantitatively using stereology. In addition, the weight of bo...

This study investigated the effects of supplementing Achyranthes Japonica Nakai (AJN) root extract to diet broiler chicks on growth performance, nutrient digestibility, caecum microbiota, excreta gas emission, and relative weight organs. A total 270 one-day-old Ross 308 (42.11 ± 0.18 g) were randomly allotted into three dietary treatments according initial body weight. Each treatment had five r...

This study was designed to investigate the effects of different levels of Tarragon powder on general performance and Anetometric, properties of digestive system of male broiler chickens. 200 one-day-old Ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. Experimental diets were set...

In order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, Ross 308 strain. Poultry by-product meal was prepared from two slaughter house in Alborz province. Samples were sent to laboratory for determination of chemical analysis. The birds received commercial broiler starter...

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. ...
