Growth, feed consumption and efficiency of tested boars. 1980

K J Drewry

Daily gain, daily feed and feed efficiency (F:G) records were analyzed for 305 boar pairs (130 Duroc, 76 Hampshire, 35 Spot and 64 Yorkshire) tested at the Indiana Boar Test Station in 1975 and 1976. Residual phenotypic correlations indicated that faster-gaining pairs were on test fewer days, had larger daily feed intakes, were fatter at 104 kg and required less feed per kilogram gain. Pairs with larger daily feed intakes were on test fewer days, were fatter at 104 kg and required more feed per kilogram gain. At the same daily feed intake, pairs with more backfat tended to have lower daily gains and require more feed per kilogram gain. At the same daily gain level, pairs with more backfat had larger daily feed intakes and required more feed per kilogram gain. At the same feed efficiency level, pairs with larger daily gains had larger daily feed intakes, and pairs with more backfat had larger daily gains and daily feed intakes. At the same backfat level, pairs with larger daily feed intakes required more feed per kilogram gain, and pairs with larger daily gains had larger daily feed intakes and required less feed per kilogram gain.
