【摘要】 对香猪的生长和繁殖性能进行了测定,结果表明:香猪体型小、生长慢,18 月龄公、母猪的体重仅为36．33±2．55kg～37．33±1．55kg和41．73±7．26kg～43． 13±6.13kg,但不同世代香猪的生长性能相似,是一性能稳定的小型猪种;香猪的性成熟早,友情征状和产仔、哺乳行为明显而有规律;香猪的产仔数较少,平均每窝产仔6．61±1．88头～6．89±1．95头,但哺育率较高,达86．49％～92．78％．本研究为香猪的繁育和开发提供了科学依据．更多还原

【Abstract】 The measurements on growth and reproductive performances of xiang pigs were carried out at a breeding farm in Shanghai. The results showed that xiang pigs had smaller size and lower growth rate, and the weight of boar pigs and gilts at 18 months old stage were respectively 36. 33 ± 2. 55kg ~ 37. 33 ± 1. 55kg and 41. 73 ±7. 26kg ~43. 13 ±6. 13kg, but the growth performances were similar between the first generation and the second generation xiang pigs, and it was a mini - pig breed in a stable growth performances. Meanwhile, xiang pigs had earlier age of sex maturity, obvious estrous signs and regular farrowing and lactation behavior. It also showed that the litter size of xiang pigs were only 6. 61 ±1. 88-6. 89 ±1. 95, but the livability of piglet in lactation period were 86.49% ~ 92. 78% . This study will provide scientific evidences for us on the breeding and the developing of xiang pigs.更多还原
