德系安哥拉繁殖母兔产毛营养需要的研究

THE NUTRIENT REQUIREMENTS OF THE ANGORA DOES REPRODUCTION PERIOD FOR WOOL PRODUCTIONN

作者用219只1～2岁德系安哥拉繁殖母兔分3期16组进行了每期80天的试验以测定营养需要量。试验得出:对80％的母兔处于妊娠或哺乳状态、每日产毛2克、日增重6克以上的母兔群,适宜的日粮营养成分含量为:消化能10.5兆焦耳/公斤,粗蛋白质16％,可消化粗蛋白质11％,粗纤维15％,蛋氨酸0.8％,赖氨酸0.7％。每日每兔需消化能1715千焦耳,粗蛋白质26.4克,可消化粗蛋白质18.2克,颗粒料165克。

Three sets,sixteen groupes of experiments with a total of 219 Angora does Were carried out for the measurement of the nutrient requirements of the does in reproduction period for wool production. Each set of the test lasted 80 days. The diets mainly consisted of afalfa meal, corn, wheat meal, barley, oat, rapeseed meal, linseed meal, soybean meal, and fish meal. The results showed that for the doe population, 80% of which were in pregnancy or lactation, with a wool yield of more than 2 grams per day and daily gain of 6 grams or above per rabbit,,the proper contents of the nutrients of the diet were recommended as following:2500 kilocalories per kilogram of digestible energy(DE), 16% crude protein(CP), 11% digested crude protein(DCP), 15% crude fiber, 0.8% methionine, 0.7% lysine and 0.7% argnine. The daily nutrient requirements per rabbit were 410 kilocalories DE, 26.4 grams CP, 18.2 grams DCP and more than 165 grams pelltes.
