Study On Economic Benifits Of Premium Oats To Promote Fresh Cows

China's dairy industry is undergoing a transition from quantitative to qualitative and profitable,and the transition from traditional dairy industry to modern dairy industry.The “cost reduction and efficiency increase” has become a constant topic during the transition period and even after the dairy industry.As the main source of roughage in China,Leymus chinensis has caused a certain degree of restriction and impact on the post-production performance of dairy cows;while the Oatmeal as a quality roughage can improve the quality of milk better,and its cost is higher than that of Leymus chinensis,which has not been accepted by everyone.The project aims at investigating the effect of oat to substitute Leymus chinensis on the production performance of new dairy cows in order to find an optimal alternative,and analyzing the economic benefits of input and output,and ultimately achieving the purpose of cost reduction and efficiency increasing.This topic studied the different weight of oat grass in the early stage of dry milk to replace the Northeast goat grass on the production performance of new dairy cows,blood biochemical index,calf birth weight,midwifery rate and the incidence of postpartum diseases;At the same time,according to the increase of production performance and the decrease of disease incidence,the decrease of veterinary drug investment.In order to provide some theoretical support for the substitution of coarse fodder in China's dairy industry,the paper calculates the input and output of various aspects and computes the economic benefits of the project.In this experiment,the age,the fetal time and the body condition are equal,the dry milk period of healthy Holstein cows 300,divided into 3 groups,each group randomly divided into 2 treatment groups,as the control group and the test group;pre-trial period the cattle were free to feed and drink freely all day.The 8-week pre-natal control group was fed with whole leymus chinensis diets,the experimental group used 1kg,2kg and 3kg to replace the equivalent Leymus chinensis,respectively,as test I,test Group II and Test III group,and the dairy cows were fed the same ration after childbirth.The dry matter intake,milk yield,newborn weight and blood biochemical index of dairy cows were measured,and the rate of postpartum birth and morbidity of postpartum diseases were counted.The results showed that dry-milk pre-feeding 1kg,2kg,and 3kg oats can increase the dry matter intake of dry cows at the early stage of milk,and the increase rates were 5.06%,9.13%,and 9.38%,respectively,and significantly(P < 0.05).Oat grass feeding in the early stage of dry milk can reduce the rate of artificial midwifery in the calving of dairy cows,with the reduction ratios of 1.93%,3.28%,and 3.33%,respectively.The proportion of midwifery in the 3kg oat replacement group has the largest decline,and the best results are obtained.The birth weight of cattle increased slightly,but the difference was not significant(P>0.05).Feeding oat grass at the early stage of dry milk can significantly reduce the incidence of postpartum ketosis in dairy cows.It can also reduce the incidence of mastitis,four stomach shifts,postpartum spasms,diarrhea,and acidosis within 60 days after delivery,but the result is not significant.The use of oat grass as a substitute for Leymus chinensis in the early stage of dry milk can increase the milk production of newly-produced dairy cows,which is related to the increase of dry matter intake of cows in the early stage of dry milk;among them,1kg,2kg,and 3kg oat grass substitutes.The milk production was increased by 1.37%,1.89%,and 2.19%,respectively;the milk yield of the 3kg oat replacement group increased the most.From the economics of income analysis,found that the three experimental groups have increased the gains to varying degrees,and 2kg replacement group has the most obvious improvement effect,single head cattle as high as 304.1 yuan;This also shows that oats replace the theory of the This increase in efficiency has played an important role in promoting and raising the industry's revenue by about 1.6 billion yuan.The results of enterprise internal promotion show that oat grass instead of sheep feeding dry colostrum cattle,not only increased milk production,reduce the incidence of postpartum(lactating dairy cattle increase 0.6kg;kg milk and veterinary drugs cost decreased by 0.05 yuan),from the profit elevation,8 months or so of time for the enterprise to create more than 3 million yuan of income;The research on this subject has played a great role in promoting the reduction of the efficiency of the current situation.
