Using distillers dried grains with solubles (DDGS) as a feed ingredient in poultry nutrition has lately been increased. This study was conducted to evaluate the effect of adding different dietary levels of DDGS on the productive performance of broiler chicks from 1 to 35 d of age. Two hundred forty one-d-old broiler chicks were randomly distributed among 3 treatment groups with eight replicates...
Effect of different sources of fat on performance of broiler chicks was studied. Three hundred and thirty six chicks were divided into 42 groups of 8 chicks per group. Seven isoenergetic and isonitrogenous diets, mainly based on corn and soybean meal were prepared and fed. These treatments were as follows: corn + soybean meal + (5% tallow, 5% cotton seed crude oil, 5% cotton seed soapstock, 2.5...
two experiments were conducted to evaluate the effects of thyroxin in ovo injection and post hatch arginine feed supplementation on performance and cold tolerance acquisition in broilers. in experiment 1, a total of 2400 hatchings eggs were randomly assigned to four treatments: positive controls (intact or pricked with a needle), negative control (intact egg), injected with distilled water and ...
introduction : antibiotic feed additives have long been used as growth promoters (10). however, consumers and health authorities increasingly dictate that the use of synthetic food additives should be phased out and, where possible, only natural products should be used. hence, alternatives from natural sources with potential antioxidant activity are investigated (16). olive leaves are a good so...
This experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (Cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. The chicks were randomly distr...
An experiment was conducted to assess the effect of dietary supplementation of garlic (Allium sativum) and fenugreek (Trigonella foenum-graecum L.) seed powder as herbal feed additives on growth performance, carcass characteristics and economics of feeding in broilers. A total of 320 day old broiler chicks of Cobb-400 strain were divided into four treatment groups with 4 replicates of 20 chicks...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
The current study was attempted to investigate the effect of Mr. Trivedi’s biofield energy treated energized water on chicken. The total 4200 chicks were equally divided into two groups i.e. control and treated. The biofield treated energized water was provided to the treated chicks, while the control chicks were drunk with standard drinking water. During the experiment the parameters such as m...
An experiment was conducted to determine the effect of different levels of potato replacing maizeseed on performance characteristicsand immunes system of broiler chicken in a completely randomized design. A total of 220 broiler chicks were randomly assigned to 5 treatment groups, with 4 replicates of 11 birds each. The chicks in the first group were fed basal diet (control), 2nd and 3rd groups ...
A 3 to 4 week feed restriction of about 20% to 25% of the free intake is widely applied in rabbit breeding systems to reduce post-weaning digestive disorders. However, a short intensive feed restriction is described in few studies and can be beneficial for growing rabbits due to a longer re-alimentation period. The aim of this study was to evaluate the effect of ad libitum (AL) and two restrict...
