The main objective of broiler rearing industry is production of high quality broiler carcasses that will be acceptable for consumers; Acceptability depends on the quality and quantity of edible parts of carcasses, and the amount of muscle mass in carcass. Feeding strategy in growing broiler chickens should be to produce animals with maximum lean body mass, highest feed conversion ratio and maximum body weight. Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains. That early-life fast growth rate is accompanied by a number of problems, such as body fat deposition, high incidence of metabolic disorders, high mortality, and high incidence of skeletal diseases. The feed restriction programs is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken in alleviate the incidence of some metabolic diseases and can be used to produce a leaner bird and reduce the unfavorable effects of fat on human health, and to reduce fat deposition in broiler carcasses could be profitable in broiler chickens production. This article implicated on new findings in about different feed restriction programs effects on production efficiency and carcass quality in broiler chickens.

Improvement production efficiency and carcass quality through feed restriction programs in broiler chickens
