摘　　要：旨在统计分析新加系种猪的繁殖性能及其子代的生长性能。对正常生产的新加系种猪1胎和2胎分娩后24 h内的总产仔数、产活仔数、仔猪初生窝重等繁殖性状进行统计,同时对新加系种猪生产的第1批子代初生重、21日龄个体重、达65 kg体重日龄、达120 kg体重日龄、120 kg体重背膘厚和眼肌厚以及采食量等生长性状测定统计,并对结果进行了差异分析。结果显示:大约克母猪第1胎的平均总产仔数和平均产活仔数均极显著高于杜洛克母猪(P<0.01),长白母猪第1胎的平均总产仔数和平均产活仔数均极显著高于杜洛克母猪(P<0.01);大约克母猪第2胎的平均总产仔数和平均产活仔数均极显著高于长白母猪和杜洛克母猪(P<0.01),长白母猪第2胎的平均总产仔数和平均产活仔数均极显著高于杜洛克母猪(P<0.01);大约克母猪第2胎的平均总产仔数和平均产活仔数均极显著高于第1胎(P<0.01);杜洛克母猪第2胎的平均总产仔数显著高于第1胎(P<0.05),平均产活仔数极显著高于第1胎(P<0.01)。子代生长性能,大约克公猪的平均日采食量显著高于长白公猪(P<0.05),长白公猪显著高于杜洛克公猪(P<0.05);大约克公猪的平均日增重显著高于杜洛克公猪(P<0.05),长白公猪显著高于杜洛克公猪(P<0.05);大约克公猪的平均料重比极显著高于杜洛克公猪(P<0.01),长白公猪极显著高于杜洛克公猪(P<0.01)。大约克母猪的平均日采食量极显著高于杜洛克母猪(P<0.01),长白母猪极显著高于杜洛克母猪(P<0.01);大约克母猪的平均料重比显著高于杜洛克母猪(P<0.05),长白母猪显著高于杜洛克母猪(P<0.05)。大群测定结果显示,大约克的平均日增重显著高于杜洛克(P<0.05),长白显著高于杜洛克(P<0.05);大约克120 kg体重背膘厚极显著高于长白(P<0.01),长白极显著高于杜洛克(P<0.01);大约克120 kg体重眼肌厚极显著高于长白(P<0.01),杜洛克极显著高于大�This experiment was to count and analyze the reproductive performance of the Canadian new pig lines and the growth performance of their offspring.The reproductive traits such as total litter size,born alive and litter weight at birth within 24 hours after farrowing of the first and second parity Canadian new pig lines at normal productive status were counted.At the same time,the growth traits such as birth weight,body weight at 21 days,65 kg body weight day and 120 kg body weight day,back fat depth and loin eye depth at 120 kg,and feed intake of the first batch of offspring produced by the Canadian new pig lines were measured and counted,and the results were statistically analyzed.The results showed as follows:For the Yorkshire sows,the average total born number and the average born alive number were significantly higher than those of the Duroc sows for the first parity(P<0.01).For the Landrace sows,the average total born number and the average born alive number were significantly higher than those of the Duroc sows for the first parity(P<0.01).For the Yorkshire sows,the average total born number and the average born alive number were significantly higher than those of the Duroc sows and Landrace sows for the second parity(P<0.01).For the Landrace sows,the average total born number and the average born alive number were significantly higher than those of the Duroc sows for the second parity(P<0.01).For the Yorkshire sows,the average total born number and the average born alive number were significantly higher for the second parity than for the first parity(P<0.01).For the Duroc sows,the average total born number was significantly higher for the second parity than for the first parity(P<0.05),and the average born alive number was significantly higher for the second parity than for the first parity(P<0.01).For the growth traits of the offspring,the average daily feed intake of the Yorkshire boars was significantly higher than that of the Landrace ones(P<0.05),the average daily feed intake of the Landrace boars was
