不同类型奶牛场牛奶乳脂率及酸度变化特点研究

The Study on The Changes of The Milk Fat Percentage and Milk Acidity in Different Types of Dairy Cattle Farm

奶牛生产方式是影响奶牛奶产量和质量的重要因素。本文通过对兰州市晏家坪奶牛养殖小区、甘肃农业大学实验奶牛场、兰州市个体养殖户三种不同类型奶牛场的牛奶乳脂率及酸度指标分析,表明不同生产方式下牛奶质量差别较大,以相对规模化、集约化生产的奶牛养殖小区牛奶质量最好,个体养殖户牛奶质量较差。因此,在奶牛生产中,采用规模化、集约化的生产模式是保证牛奶质量的重要措施之一。

The feeding and management of dairy cattle are main factors that affact the quality of milk. By analyzing the milk fat percentage and milk acidity of YanJiaPing dairy cattle feeding sector in Lanzhou city and experimental dairy cattle farm of Gansu Agri- cultural University and small dairy cattle farms in LanZhou , The result shows that the quality of milk is distinctly different among the different dairy cattle farms and the quality of the dairy cattle garden with concentrated management and experimental dairy cattle farm is better than the small dairy cattle farms. It is one of main ways that guarantee the milk quality to use concentrated feeding and management in the dairy cattle garden.
