EFFECT OF ENERGO-PROTEIC RATIO BY FEED OF BROILERS FROM 1 DAY TO 48 DAYS

ANA DRIHA, P. OPREA, D DRINCEANU, C. JULEAN

Abstract


In this experiment we have studied the bioproductives effects of energy-protein ratio at diferents levels of crude protein and methabolizable energy, concerining whith broilers age.The experiments was carried out from one day chicken which was feeded whith in three periods. First period from 1 day till 20 days, secod period from 21 dys to 30 days threed period from 31 till 48 days.The experiments was brought about in four experimental group. Each group was feeded differently concerning energy-protein ratio. At the 48 broilers was slaughtered and cutted into anatomical parts like breast in-bone,wings,thighs,back and neck and fat pad.For all period the chicken was weighted randomly periodicaily and also was estimeted feed conversion and feed consuming.
