Feeding programs for commercial turkeys at the finishing stage

Abstract

ABSTRACT: The aim of this study was to assess the effect of feeding management on performance and carcass yield of male turkeys during finishing stage. 920 male turkeys were used, which were housed in 40 pens; each pen was comprised of experimental unit. The birds, from 91 to 154 days, were submitted to four feeding managements, based on feed intake, that were: ad libitum, where feed was permanently available to birds; controlled with a daily supply of 100% of recommended feed amount; controlled with 95% of recommended daily feed amount, and controlled with 90% of recommended daily feed amount. Each feeding treatment had ten replicates of 23 birds each. Controlled or restricted feeding management reduced feed intake, average weight, and weight gain (P <0.05), and worsened feed conversion (P <0.05). Carcass and leg weight were reduced (P <0.05) from the 5% restriction related to the recommended. Breast weight was reduced (P <0.05) with a restriction of 10%. No differences were seen when compared to carcass and leg yield and fat deposition (P> 0.05), only breast yield was reduced (P<0.05) when the birds received 90% of that recommended by the lineage, compared to the ad libitum feed management. The feeding management of male turkeys with restriction of the recommended feed amount during the finishing stage had a negative effect on the performance of the birds. However, controlled feeding at 100% of recommended to the lineage reduced feed intake and did not change the carcass weight, breast or leg yield, or fat deposition.
