【摘要】：为充分利用当地饲料资源,测定和分析胡麻饼常规营养成分,然后将其放入装有永久性瘤胃瘘管陕北白绒山羊的瘤胃内,用尼龙袋法测定和分析了胡麻饼在6、12、24、48 h内干物质(DM)、粗蛋白(CP)、粗纤维(CF)的瘤胃消失率。结果表明:胡麻饼CP、CF、粗脂肪(EE)、粗灰分(CA)、Ca和P分别为36.2%、8.98%、7.82%、7.02%、0.47%、0.81%。在陕北白绒山羊瘤胃内6、12、24、48 h内,干物质消失率分别为55.11%、78.75%、78.77%、85.75%,CP消失率分别为52.82%、61.94%、72.4%、75.32%,CF消失率分别为23.9%、25.1%、26.2%、28.6%。因此认为,胡麻饼CP和EE含量较高,DM和CP消失率在24 h内可达78.77%和72.4%,消化利用效果较好。
[Abstract]:In order to make full use of the local feed resources, the routine nutritional components of flax cake were determined and analyzed, and then put into the rumen of the white cashmere goat with permanent rumen fistula. The rumen disappearance rate of (DM), crude protein (CP), crude fiber (CF) in flax cake was determined and analyzed by nylon bag method within 48 h. The results showed that (CA) Ca and P were 36.2, 7.82 and 7.82, respectively, and 0.470.81. The results showed that (CA) Ca and P were 0.470.81 and 0.471.The results showed that (CA) Ca and P were 36.2% and 8.98%, 7.82% and 7.82%, respectively. Within 48 hours, the disappearance rate of dry matter in the rumen of the white cashmere goats was 55.118.75 and 78.77.75, respectively. The disappearance rate of CP was 52.82.920.72.4and 75.320.The disappearance rate of CF was 23.90.25.1and 26.2nil and 28.66.6respectively in the rumen of the white cashmere goats in the north of Shaanxi Province, and the disappearance rate of CP was 52.82.92.42 and 75.320.The disappearing rate of the dry matter in the rumen of the white cashmere goats was 55.117.75 and 78.75.75, respectively. It was concluded that the disappearance rate of CP and CP in flax cake was 78.77% and 72.4% within 24 h, and the digestibility and utilization were better.
