| 摘 要： | 为了研究不同日粮精粗比对滩寒杂羊生产性能、健康状况以及养殖效益的影响,选择健康断奶滩寒杂种羊48只,随机分为3组,根据当地饲草资源配制精粗比分别为65∶35、60∶40、55∶45的全混合颗粒日粮进行饲养试验。结果表明,利用3个精粗比日粮育肥的断奶滩寒杂羊均处于健康状态,采用60∶40精粗比日粮育肥其生长性能较好,养殖效益最高,育肥期在60 d左右效益最佳。

Effect of Forage-to-concentrate Ratio in Diets of Hybrids of Tan SheepxSmall-tailed Han Sheep on Reproductive Performance and Blood Biochemical Parameters |
| |
| Abstract: | The aim of this study was to assess the effect of different forage-to-concentrate ratios in diets of hybrids of Tan sheep~ Small-tailed Han sheep on reproductive performance, healthy status and fattening economic benefit. A total of 48 healthy weaned hybrid lambs were randomly assigned to three groups and were fed with the pelleted total mixed ration. The forage-to-concentrate ratio in diet of the three groups were 65：35, 60：40 and 55：45, respectively. The results showed that the fattening hybrid lambs fed the diet with the three designed forage-to-concentrate ratios were all in healthy status; the hybrid lambs fed diet with forage-to- concentrate ratio of 60：40 had the best growth performance and the highest fattening economic benefit; the recommended fattening period was approximately 60 days. |
