Growth Performance and Economic Benefit Analysis of Duroc and PIC with Canadian Binary Sows
摘要
Abstract
To introduce and select terminal father for pig farms,and select commercial pig combina-tions that meet the market demand,different lines and breeds,including Danish Duroc,French Duroc,A-merican Duroc and PIC boars were selected and crossed with 2～4 parities of Canadian line binary sows to determine the reproductive performance of sows,daily weight gain of fattening pigs,feed intake,feed-to-meat ratio,death and culling rate,and economic efficiency and other indexes.The results showed in terms of reproductive performance,the total litter size and healthy litter size of Danish Duroc group(DC)were significantly higher than those of American Duroc group(P＜0.05).The litter weight of healthy newborns in French Duroc group(FC)was significantly higher than that in American Duroc group(MC)(P＜0.05).Average birth weight in MC group was significantly higher than that in PIC group(P＜0.05).In terms of growth performance of commercial pigs,DC group had the shortest age of 100kg of correction.The ratio of feed to meat in MC group at 170 days of age was significantly higher than that in PC group(P＜0.05).The daily gain at 170 days of age in DC group was significantly higher than that in PC group(P＜0.05).The slaughtering weight of DC group was significantly higher than that of the other three groups(P＜0.05).The average daily gain in DC group was significantly higher than that in PC group(P＜0.05).The ratio of feed to meat in MC group was significantly higher than that in PC group(P＜0.05).FC group had the lowest death and culling rate of 2％.Under the same conditions of growth and fattening,Danish Duroc group line has the highest num-ber of litters and has obvious advantage in growth rate and the best economic benefit.关键词
