Abstract: Three-way crossbreeding trials were conducted using Dorper ram, Poll Dorset ram, German mutton merino ram and ewe hybrid of Small-tail Han and Suffolk, respectively. The productive performance of the hybrids was determined. The results showed that the pre-slaughter empty body weight, carcass weight and slaughtering percentage of hybrids of Dorper×Small-tail Han and Suffolk reached 43.0 kg, 22.4 kg and 52.07%, respectively, and the three indicators were all higher than those of hybrids Poll Dorset×Small-tail Han and Suffolk and German mutton merino ×Small-tail Han and Suffolk; the daily gain of hybrids of Dorperx Small-tail Han and Suffolk reached 262.3 g which was higher and significantly higher than that of hybrids of Poll Dorset×Small- tail Hart and Suffolk and German mutton merino×Small-tail Han and Suffolk, respectively.
