Abstract
Este trabalho avaliou as características de carcaça de suínos alimentados do desmame ao abate em comedouro de acesso único equipado ou não com bebedouro. Foram utilizados 96 animais (48 machos castrados e 48 fêmeas) com peso vivo médio final de 90,5kg distribuídos em esquema fatorial 2x2 (dos tipos de comedouros - acesso único, acesso único equipado com bebedouro; e dois sexos). As carcaças foram avaliadas pelo Método Brasileiro de Classificação de Carcaças e pelo Método de Dissecação. O rendimento de carne magra foi superior em 3,7% (PThis study was carried out to evaluate the carcass characteristics of pigs fed from weaning to slaughter in single space feeders equipped or not with drinker. Ninety-six animals (48 barrows and 48 females) with 90kg live weight were distributed in a factorial design (two feeder types - no drinker; conjugated with drinker; and two sexes). The carcasses were evaluated by the Brazilian Method of Carcasses Classification and by the Dissection Method. The meat yield was 3.7% higher (P<0.05) in animals fed in dry feeders and 2.6% slower (P<0.05) in barrows. The carcass yield was not affected by the feeder type, but was 1.3% higher (P<0.05) in barrows. The loin muscle area was not affected by the feeder type and sex. The fat area was 8.8% higher (P<0.05) in the animals fed in wet feeders and 16.8% in barrows. The backfat thickness was 11.0% higher (P<0.05) in the animals fed in wet feeders and 11.2% in barrows. The relation meat/fat was 10.9% higher (P<0.05) in animals fed in dry feeders and 21.6% in females. The ham weight was not affected by feeder type, but it was 5.9% higher (P<0.05) in barrows. Feeding pigs from weaning to slaughter in wet feeders reduce lean and increase fat in carcass.
