Effects of Fermented Feed Mainly Containing General Chicory and Corn Stover on Growth Performance and Economic Benefits of Simmental Crossbred Beef Cattle
[目的]旨在研究将军菊苣和玉米秸秆为主的发酵饲料对西门塔尔杂交肉牛育肥生产性能和经济效益的影响.[方法]选取100头体重300 kg左右的健康西门塔尔杂交肉牛作为试验动物,随机分为4组,每组25头牛,设5个重复栏,每个重复栏5头牛.对照组饲喂基础全混合日粮,试验Ⅰ组以等价原则使用发酵饲料替代1 kg精料,试验Ⅱ组以等干物质量原则使用发酵饲料替代1 kg精料,试验Ⅲ组在试验Ⅰ组基础上补充小米秸秆使其与对照组干物质量相等.试验期共75 d,其中预试期15 d,正试期60 d.[结果]试验Ⅱ组试验期间的总增重、日增重最高,与对照组相比,分别提升了4.98%和5.22%;试验Ⅰ组料重比和每千克增重饲料成本最低,与对照组相比,分别下降5.87%和2.85%.试验结束后,试验Ⅰ组养殖收益最好,与对照组相比每头牛毛收入增加79.46元,毛利润提高5.07%.[结论]日粮中使用以将军菊苣和玉米秸秆为主的发酵饲料等价替代1 kg精料,可提高西门塔尔杂交肉牛育肥前中期饲料转化效率,改善肉牛日增重,提升养殖效益.
[Objective]This study aimed to evaluated the effects of fermented feed mainly containing general chicory(Cichorium intybus 'General')and corn stover Cichorium intybus and corn stalks feed on growth performance and economic benefits in of Simmental crossbred beef cattle.[Methods]A total of 100 One hundred Simmental crossbred beef cattle(approximatelyabout 300 kg weight)were randomly assigned to four dietary groups,with 5 replicates per group and 5 cattle per replicate.Beef cattle in the control group were fed a basal diet,while those in Group I were fed the same basal diet in which 1 kg of concentrate was replaced with the fermented feed on an equivalent value basis,those in Group II were fed the basal diet with 1 kg of concentrate replaced by the fermented feed on an equivalent dry matter basis,and those in Group III were fed the same diet as Group I,but supplemented with corn stover to achieve the same dry matter content as the control group.The experiment lasted 75 days,including a 15-day pre-experimental period and a 60-day formal experimental period.[Results]The results showed that beef cattle in Group II had significantly higher total weight gain and average daily gain,with improvements of 4.98%and 5.22%,respectively,compared to the control group.Beef cattle in Group I had the lowest feed meat ratio and feed cost per kg weight gain(decreased by 5.87%and 2.85%,respectively)compared to the control group.Ultimately,the best economic returns were achieved in Group I,with the profit per head increased by 79.46 RMB and the gross profit increased by 5.07%compared to the control group.[Conclusion]In conclusion,using fermented Cichorium intybus and corn stalks feed as an isointrogenous replacement for concentrate by 1kg in finishing cattle diets improves feed efficiency,growth performance,and economic benefits.dietary inclusion of fermented feed mainly containing General Chicory and corn stover as an equivalent replacement for 1 kg of concentrate can improve feed conversion efficiency in the early-to-middle fattening stage,enhance daily weight gain,and increase breeding profitability in Simmental crossbred beef cattle.
