FEED RESTRICTION IN BROILER CHICKENS PRODUCTION

Abstract: 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 ascites, lameness, mortality, and sudden death syndrome and so improving feed conversion and reducing feed cost. Also to produce a leaner bird and reduce the unfavourable effects of fat on human health, and to reduce fat deposition in broiler carcasses using of feed restriction programs can be profitable in broiler chickens production. This article surveys new findings in feed restriction of broilers and evaluates the application of feed restriction methods to broiler chicken production. Key words: broiler chicken, feed restriction, compensatory growth
