Effect of Different Domestic Alfalfa Adding Content on Nutritional Quality of Local Fresh Milk
摘要
Abstract
Domestic alfalfa supply has the obvious price advantage in the local dairy farms,but its feasible amount of feeding and the effect on the quality of fresh milk are still unclear for a lack of scientific experimental evidence.The alfalfa growed in Daqing city,Heilongjiang province was used in the present study,and one-year feeding experiment was performed to analyze the effect of alfalfa on the quality of fresh milk in the local 9 large-scale dairy farms.The results showed that compared with control group,the nutrient of fresh milk were not significantly improred when the amout of alfalfa was 3 kg/d (P >0.05).While the cude protein and dry matter of fresh milk were sig-nificantly increased (P <0.05)when the amount of alfalfa addition in the diet was 6 kg/d,but the milk fat and lactose percentage were not significantly affected (P <0.05).Moreover,the alfalfa addition in di-et resulted in a significantly increase of unsaturated fatty acid percentage (P <0.05)and optimization of fatty acid composition of the fresh milk.In conclusion,it was helpful to improve the nutritional quality of fresh milk by changing the alfalfa amount of 3 kg/d,which was commonly used at present in dairy farms, to be 6 kg/d.关键词
