摘要/Abstract

摘要： 为研究新引进的烟台黑猪不同组合的繁殖性能及其后代的生长育肥性能，试验测定了烟台黑猪纯繁及其杂交组合的繁殖性能。选择 3头体重30 kg左右的烟台黑猪和48头长白猪与烟台黑猪的杂交后代长烟二元仔猪，进行育肥试验。结果发现，烟台黑猪纯繁仔猪21日龄个体重、21日龄窝重、35日龄个体重分别比长烟二元仔猪显著提高 16.74%（P＜0.05）、26.19%（P＜0.05）和24.44%（P＜0.05）。烟台黑猪母猪组和阉公猪组的背膘厚，分别比烟台黑猪公猪组提高 26.38%（P＜0.05）和24.56%（P＜0.05）；烟台黑猪公猪组的活体瘦肉率分别比母猪组和阉公猪组提高3.75%（P＜0.05）和4.46%（P＜0.01）。长烟二元猪公猪组的平均日增重比母猪组提高 11.69%（P＜0.01）。烟台黑猪和长烟二元猪比较，烟台黑猪体长比长烟猪极显著提高5.70%（P＜0.01）；长烟猪胸围比烟台黑猪显著提高4.95%（P＜0.05）。结果表明，杂交对烟台黑猪的总产仔数和产活仔数及仔猪初生个体重无明显差异，但对仔猪的21日龄个体重、21日龄窝重、35日龄个体重有降低的趋势，需进一步验证。
