摘要
为了解广灵大尾羊的羔羊育肥效果,以期为提高养殖户的经济效益提供技术支撑,于2011年5月8日至7月7日对广灵大尾羊和蒙系羊的4月龄断奶羔羊采用全舍饲育肥方式进行60 d育肥试验。结果表明,广灵大尾羊的4月龄断奶羔羊育肥期的始质量、末质量、增质量和日增质量分别为25.31,43.27,17.95 kg,299.23 g,蒙系同龄羔羊分别为24.94,39.61,14.67 kg,244.49 g;经Excel统计分析和t检验,2个品种的羔羊育肥期的末质量、增质量和日增质量均达极显著差异(P<0.01)。试验结果表明,育肥是增加养羊经济效益的有效措施,且广灵大尾羊的羔羊有很好的育肥效果。
This study explored fattening test on lamb of Guangling Fat-tailed sheep（GLFT）, to provide technical support for benefit improvement. The trial selected 4-month weaned lambs, half of them were GuangLing Fat-tailed sheep and the others were Mongolia sheep, to fat feeding in barn for 60 days. The results indicated that during fattening period, initial weight of GLFT lamb was 25.31 kg and final weight, gain weight, average daily gain were 43.27, 17.95 kg, 299.23 g respectively; Corresponding indicators of Mongolia sheep were 24.94, 39.61, 14.67 kg, 244.49 g. According to the statistical analysis, there were significant differences in final weight, gain weight,average daily gain between GLFT lamb and Mongolia sheep. The result showed that Guangling fat-tailed sheep had better fattening effect and the fattening was is an effective measure to increase culture benefits.
