摘　　要：【目的】探索猪新品系-HN的繁殖性能及年生产力.【方法】研究以60头‘大白母猪’2～4胎繁殖性能为对照,对45头新品系-HN母猪2～4胎窝总产仔数、产活仔数、断奶存活仔数、仔猪育成率、初生个体质量、初生窝质量、21日龄个体质量、21日龄窝质量、断奶个体质量、断奶窝质量和乳头数等指标进行测定,比较分析了两者之间的繁殖性能、年生产力及每头母猪年提供断奶仔猪带来的经济效益.【结果】新品系-HN猪总产仔数(14.81头)、产活仔数(14.14头)、断奶存活仔数(13.28头)、初生窝质量(16.88 kg)、断奶窝质量(81.03 kg)和乳头数(7.98对)都极显著高于‘大白猪’(P<0.01);初生个体质量(1.19 kg)、21日龄个体质量(4.00 kg)和断奶个体质量(6.10 kg)都极显著低于‘大白猪’(P<0.01);21日龄窝质量(53.36 kg)显著高于‘大白猪’(P<0.05);仔猪育成率为93.92%,高出‘大白猪’11.78%;每头新品系-HN猪和‘大白猪’母猪年提供断奶仔猪数分别为27.90头和17.31头,根据当前市场价格纯盈利分别达6 524.95元和3 940.43元.【结论】新品系-HN猪产仔性能、泌乳性能、成活率、年生产力和每头母猪年提供断奶仔猪数带来的经济效益都优于‘大白猪’.【Objective】This study is aimed to find the characteristic between reproductive performance and annual productivity in the swine new strain-HN.【Method】The reproductive performance of new strain-HN(45 heads,second o fourth parity)were compared with the control(60 heads of‘Yorkshire’,second o fourth parity)by measuring the index including total number of sow born(TNB),number born alive,weaning survival,rate of raising,individual and litter weight at different stages(birth,21days and weaning)and teat number.Economic efficiency was evaluated as well through comparing the reproductive performance,annual productivity and weaned piglet numbers between two groups.【Result】The result showed that the average number of pig born(14.81 heads),number of born alive(14.14 heads),survival to weaning(13.28 heads),litter weight at birth(16.88 kg),litter weight at weaning(81.03 kg)and teat number(7.98 pairs)in new strain-HN group were significantly higher(P<0.01)than those in‘Yorkshire group’.However,the individual weight at birth(1.19 kg),individual weight at 21days(4.00 kg)and individual weight at weaning(6.10 kg)were significantly lower(P<0.01)than those in‘Yorkshire group’.The litter weight at 21days(53.36 kg)was significantly higher(P<0.05),the rate of raising was 93.92%,11.78% higher than that of‘Yorkshire’.New strain-HN and‘Yorkshire’sow could offer 27.90 and 17.31 heads of weaned piglet per year,the pure profit was 6 524.95 and 3 940.43 yuan respectively according to the current market price.【Conclusion】The results suggested that the swine new strain-HN have advantages over‘Yorkshire’in terms of farrowing performance,milk performance,survival rate,annual productivity and economic efficiency.
