摘要
为期６０ｄ２０头奶牛的试验表明，在奶牛日粮中添加磷酸脲可使产奶量、乳脂率、乳脂量分别提高２．８％，５．６％（Ｐ＜０．０５）和８．４％（Ｐ＜０．０５），对乳密度无影响。还能解决奶牛日粮中缺磷的问题。
heads of dairy cattle had been investigated for 60 days.The results show,Adding (phosphaturia)[ CO(NH_2)]_2·H_3PO_4] to dairy cows diets had raised the milk yield, milk-fat percentage, butter fat yield by 2.8%,5.6%(P <0.05)and 8.4%(P <0.05) respectively. Phosphaturia had no effect on milk density. Using phos-phaturia as a dairy cattle’s feed additive is an effective measure to solve feed phosphorus deficiency and low milk -fatpercentage in the south of China.
