摘要
[目的]研究板栗叶、麸皮及EM菌液制成的板栗叶压缩发酵饲料替代粗饲料对肉羊生长性能及养殖经济效益的影响,为其在肉羊及其他反刍动物育肥中的应用提供理论依据。[方法]选取120只平均体质量(15±0.89)kg的迁西县当地3月龄的小尾寒羊为试验对象,将其随机分为2组,每组3个重复,每个重复20只羊,在河北省迁西县洒河桥白塔寨李春伟养殖场和河北迁西县三屯镇龙湾村龙盛养殖场同时进行试验。对照组羔羊饲喂基础饲粮,试验组羔羊饲喂自制的板栗叶压缩发酵饲料(质量比为8∶2的板栗叶与麸皮经过EM菌液厌氧发酵所得),饲喂周期120 d。分别测定每组羔羊每天采食量,在试验初期、末期称取羊群总体质量,并根据饲料成本和羊群总增质量计算利润。[结果]春伟养殖场试验组羔羊的末质量、总增质量、总耗料和平均日增质量分别比对照组显著提高78.16、77.38、401.21 kg和32.24 g/只;试验组羔羊的利润为363.64元/只,比对照组显著提高了118.24元/只。龙盛养殖场试验组羔羊的末质量、总增质量、总耗料和平均日增质量分别比对照组显著提高80.83、82.32、387.82 kg和34.30 g/只;试验组羔羊的利润为376.84元/只,比对照组显著提高了124.24元/只。[结论]使用板栗叶压缩发酵饲料替代粗饲料,可显著提高羔羊增质量与经济效益。
[Objectives]The effects of compressed and fermented feed of chestnut made from chestnut leaves,bran,and EM bacterial liquid as a substitute for roughage on the growth performance of mutton sheep and economic benefits of farming were studied to provide a theoretical basis for its application in fattening mutton sheep and other ruminant animals.[Methods]120 locally grown 3-month-old small tailed Xian lambs with an average body weight of approximately(15±0.89)kg in Qianxi County were selected and randomly divided into 2 groups,with 3 replicates in each group and 20 lambs in each replicate.Experiments were conducted simultaneously at two farms in Qianxi County,Hebei Province including LI Chunwei Farm in Baitazhai,Shaheqiao,and Longsheng Farm in Longwan Village,Santun Town.Lambs in the the control group were fed with basic feed,while lambs in the experimental group were fed with self-made compressed and fermented feed of chestnut leaves obtained by anaerobic fermentation of chestnut leaves and bran with a mass ratio of 8:2 through EM bacterial liquid,with a feeding period of 120 days.The daily feed intake of lambs in each group of was measured separately.The overall quality of the sheep herd was measured at the beginning and end of the experiment,and the profit was calculated based on the feed cost and the total weight gain of the sheep herd.[Results]The final weight,total weight gain,total material consumption,and average daily weight gain of lambs in the experimental group was significantly higher than that in the control group at Chunwei Farm,with a increase of 78.16,77.38,401.21 kg and 32.24 g/piece,respectively.The profit of lambs in the experimental group was 363.64 yuan per lamb,a significant increase of 118.24 yuan per lamb compared to that in the control group.The final weight,total weight gain,total material consumption,and average daily weight gain of lambs in the experimental group was significantly higher than that in the control group at Longsheng Farm,with a increase of 80.83,82.32,387.82 kg and 34.30 g/piece,respectively.The profit of lambs in the experimental group was 376.84 yuan per lamb,a significant increase of 124.24 yuan per lamb compared to that in the control group.[Conclusions]Using compressed and fermented feed of chestnut leaves instead of roughage can significantly improve the weight gain of lamb and economic benefits.
