Shaanxi Typical Dairy Farm Nutrition Diagnosis And Management Evaluation

China’s dairy industry is in the period of rapid development, from a variety of size and the diversity of breeding level coexist to moderate scale development stage.With the speeding up of scale, the improvement of the performance of the dairy cattle,that needs higher technology of dairy cattle nutrition management.Traditional dairy cattle nutrition is mainly focused on dairy cows diet formulation,no consider of cow management indicators, caused a lot of recipes using effect is unsatisfactory. However,evaluation of dairy cattle nutrition diagnosis, and management techniques related research rarely reported.So the purpose of this research is to through diagnosis and management lactation cows in the two typical dairy farm of shaanxi province.In order to provide theory and practice basis for promoting the efficient and stable development of dairy industry in our country. Trail1Shaanxi typical dairy farm total mixed ration nutrition diagnosisAll the lactation cows in the two dairy farm are the research objects. Analysis the basic nutrition of total mixed ration,milk yield and milk composition.The results show that,compared with the recommended standards,the total mixed ration the first layer (>19.00mm) higher than recommended.Crude protein and calcium higher than recommended,but phosphorus lower than recommended.Starch in the first farm higher than the recommended,in the second farm lower.Neutral detergent fiber in the first farm are accord with recommended,and the second farm are higher.Physical neutral detergent fiber effectively lower in the first farm,but higher in the second farm. Milk protein and fat are3.50%-3.80%and4.39%-5.30%in the first farm. They are2.93%-3.23%and1.94%-2.40%in the second farm. Somatic cell count are lower than50wan/ml,the first farm are lower than the second.Efficiency of lactation in the first higher than the second farm and the first farm can produce high quality milk.Trail2Shaanxi typical dairy farm management evaluationAll the lactation cows in the two dairy farm are the research objects,for feeder score, body condition, grading, bed rate statistics, and breeding management evaluation.The results show that, feeder score in the two dairy farm are lower than three score. Don’t play a maximum cows dry matter intake.Calving interval is too long.Cows in the first farm have higer body condition score,there are lager diferrence between each others.Cows in the second farm have lower body condition score,there are little diferrence between each others.Bed rate in the first farm are bigger than80%, conform to the standard. The second farm are smaller than80%,needs to improve.From what has been discussed above,the main problem in the two typical farms are calving interval is too long and the diet energy imbalance. Through application test of nutritional diagnosis and evaluation method of management,can timely find problems existing in the production,to improve the efficiency of the comprehensive breeding dairy cows.
