摘要
文章旨在研究两种不同营养水平日粮对湖羊羔羊养殖效果的影响,试验由山丹县畜牧技术推广站组织实施,试验时间为2022年3月20日至5月20日,试验为期60 d,在50只体重(公羔20只、母羔30只)、体质相近、生长发育正常的60日龄左右、断奶后的健康湖羊羔羊中选择30只,其中公羔10只,母羔20只,将其分为两组,每组5只公羔,10只母羔,该试验利用两种营养水平日粮饲喂湖羊羔羊,对照组营养水平为消化能9.88 MJ/kg、粗蛋白质7.16%,钙0.15%,磷0.33%;试验组营养水平为消化能9.50 MJ/kg、粗蛋白质10.32%,钙0.68%,磷0.54%。试验结果表明,由于试验组日粮中补充了微量元素,钙、磷含量高,可满足羔羊生长需要,很好地改善了湖羊羔羊互相食毛、脱毛和异食癖现象。同时,湖羊羔羊的平均日增重明显提高,其经济效益也显著提高。结论:在各养殖场可大力推广应用此技术成果,进一步提高养殖场户的经济效益。
The purpose of this paper is to study the effects of two different nutrient levels of diets on the breeding effect of Hu sheep lambs,The test was conducted from March 20 to May 20,2022.A 60-day comparative test was conducted to select the mutton sheep farm of Shunlian Agricultural and Animal Husbandry Professional Cooperative in Shandan County,which has excellent breeding foundation and conditions.Thirty lambs(10 male lambs and 20 female lambs)were selected from 50 healthy Hu lambs of about 60 days of age with normal growth and development,and divided into two groups with 5 males and 10 females in each group.In this experiment,two groups of Hu sheep were fed with diets with different nutrient levels.The nutrient levels of the control group were 9.88 MJ/kg of digestible energy,7.16%of crude protein,0.15%of calcium and 0.33%of phosphorus;Nutritional level of the test group:digestive energy 9.50 MJ/kg,crude protein 10.32%,calcium 0.68%,phosphorus 0.54%.The test results showed that the diet of the test group was supplemented with trace element additives,with high content of calcium and phosphorus,which could meet the needs of lamb growth,and well improved the phenomenon of mutual hair eating,depilation and pica of Hu sheep lambs.At the same time,the average daily gain of Hu sheep lamb was significantly increased,and its economic benefits were also significantly improved.The conclusion of the experiment is that the technical achievements can be vigorously promoted and applied in various farms to further improve the economic benefits of farmers.
