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

Abstract

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.Osnovni cilj industrije proizvodnje brojlera je proizvodnja visoko kvalitetnih trupova pilica koji ce biti prihvatljivi za potrosace. Prihvatljivost zavisi od kvaliteta i kvantiteta jestivih delova trupova, i kolicine misicne mase u polutkama. Strategija ishrane u uzgoju pilica treba da bude proizvodnja zivotinja sa maksimalnim prinosom mesa, najvisom konverzijom hrane i maksimalnom telesnom tezinom. Kontinuirana genetska selekcija i poboljsanje ishrane doveli su do veoma brzog rasta savremenih sojeva. Taj brz porast u ranom period zivota je pracen brojnim problemima, kao sto su talozenje masti u telu, visoka ucestalost metabolickih poremecaja, visok mortalitet, i visoka ucestalost oboljenja kostiju. Program ogranicenje ishrane je jedan od glavnih tehnika manipulacije krive rasta za povecanje efikasnosti proizvodnje brojlerskih pilica i ublazavanja pojave nekih metabolickih bolesti i moze da se koristi za proizvodnju mesnatijih pilica cime ce se smanjiti negativni uticaj masti na zdravlje, a manje talozenje masti u trupovima brojlerskih pilica moze biti profitabilno u proizvodnji brojlera. Ovaj rad predstavlja nova saznanja u vezi sa efektima razlicitih programa ogranicenja ishrane na efikasnosti proizvodnje i kvalitet trupa brojlera.
