无磷酸氢钙日粮对生长猪的影响研究

Study on the Effect of None Dicalcium Phosphate Diet on Growing Pigs

将48头杜×长×大三元杂交生长猪随机分为两组,分别饲喂正常磷水平日粮和无磷酸氢钙日粮,结果表明:与正常磷水平日粮相比,无磷酸氢钙日粮可显著提高磷的表观消化率(P<0.05),增加猪场的纯收入,减少粪中磷的排放以保护猪场周边的生态环境。

Forty - eight growing pigs （Duroc × Landrace × Yorkshine） were randomly allocated to two groups, one received the normal phosphorus level diet and the other received the none dicalcium phosphate diet. The results show that compared to the normal phosphorus group, the none dicalcium phosphate group could improve the phosphorus apparent digestibility signifieantly（P 〈 0.05）and increase the net income of pig farm, decrease the phosphorus output in feces as to protect the ecological environment around the intensive swine production units.
