【目的】旨在通过皮山红羊与巴什拜羊的杂交研究，培育兼具高繁殖性能和优良肉质的新型杂交羔羊，提升巴什拜羊的生产效率和经济价值。【方法】对2023—2024年皮山红羊与巴什拜羊杂交获得的羔羊，从初生至180 d，定期测量其体重、体高、体长、胸围和管围等数据指标，记录并分析其生长发育规律，对杂交效果进行评估。【结果】杂交羔羊在体高、体长、体重等关键指标上极显著高于巴什拜羊（P<0.01），杂交优势明显。【结论】皮山红羊与巴什拜羊杂交优势明显，杂交羔羊的体尺、体重都有显著提高。

【Objective】 This study aimed to conduct research on crossbreeding of Pishan red sheep and Bashbay sheep to develop a new breed of hybrid lamb with high reproductive performance and excellent meat quality, thereby enhancing the production efficiency and economic value of Bashbay sheep. 【Methods】 For hybrid lambs obtained form 2023 to 2024, regular measurements of body weight, height, length, chest circumference, and cannon bone circumference were conducted from birth to 180 days of age. The growth and development patterns of the hybrid lambs were recorded and analyzed to evaluate the crossbreeding effects. 【Results】The hybrid lambs showed extremely significant increases in key indicators such as body height, length and weight compared with Bashbay sheep(P<0.01), indicating a clear heterosis. 【Conclusion】 The crossbreeding of Pishan red sheep and Bashbay Sheep yielded obvious effects, with significant improvements in body size and weight of the hybrid lambs.
