Feed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
متن کاملEffect of Qualitative and Quantitative Feed Restriction on Growth Performance and Immune Function in Broiler Chickens*
The current study was conducted to investigate the effect of early feed restriction (FR, 8 to 14 d of age) on growth performance and immune function in broiler chickens. Birds were fed corresponding diets from 3 to 35 d of age, which consisted of three phases: starter (3 to 7 d of age), FR (8 to 14 d of age) and re-alimentation (15 to 35 d of age) phases. During the FR period, each group of bir...
متن کاملResponse of Broiler Chickens to Quantitative Feed Restriction with or without Ascorbic Acid Supplementation
Ascorbic acid (vitamin C) supplementation has been documented as a useful tool to improve the performance of laying birds reared under harsh environmental conditions. However, there is limited information on the use of ascorbic acid as a means of ameliorating the stressful conditions imposed by feed restriction. To this effect a 3 × 2 factorial experiment was carried out to evaluate the effect ...
متن کاملPreference of Broiler Chickens for Feed Color
Studying broiler preference to feed color is important for improving comfort and welfare of broilers and it may be beneficial for improving performance. The aim of the first experiment was to examine day-old chick's preference in different light colors to different feed colors. One hundred and sixty Ross 308 newly hatched broilers, never exposed to feed, were allocated into pens illuminated ...
متن کاملthe effect of early feed restriction on performance and serum thyroxin concentration of broiler chickens
an experiment was conducted to evaluate the effect of early feed restriction on performance and serum thyroxin concentration of broiler chicks. the experiment was designed in a 2×2 factorial with 5 replicates of floor pens with 12 male or female chicks in each. 240 male and/or female day-old chicks of a commercial strain (hybrow) were wing banded, weighed and randomly allocated to two treatment...
