| 摘 要： | 随着草原资源日渐匮乏,放牧饲养绒山羊已成为绒山羊养殖业发展的限制因素;改变以往的放牧饲养绒山羊的方式,舍饲绒山羊是发展绒山羊的一条途径.为此,在辽宁省盖州市辽宁绒山羊原产地,以辽宁绒山羊成年羊为试验动物,研究了在放牧和舍饲2种饲养方式下对绒山羊的饲粮组成、营养摄取状况、绒的产量、净绒率、绒长、绒细度的影响.研究表明,在放牧与舍饲条件下饲养辽宁绒山羊,所采食的饲料种类有很大差异,放牧采食的饲料种类多而营养丰富;舍饲条件下饲料种类较单一.在舍饲条件下,辽宁绒山羊绒细度有变粗的趋势,绒长、产绒量有增加的趋势.

| Abstract: | It has been recognized that the barn feeding was the suitable alternative for the cashmere goat raising instead of grazing because of grassland resource shortage.The effects of grazing and barn feeding on the diet composition,nutrients intake,cashmere yield,net cashmere rate,length of cashmere,fineness of cashmere of Liaoning Cashmere Goat were studied in Gaizhou of Liaoning Province.The results showed that the difference of between two feeding patterns was greatly significant.The ingestive feedstuff in grazing pattern was diverse and the nutrition situation was better.The cashmere showed a trend of becoming coarse and longer,and its yield becoming higher in barn feeding pattern. |
