斑点叉尾生长需要的钙源为配制全价配合饲料,美国德克萨斯大学的研究人员对饲料中的钙源和不同含量对斑点叉尾(1.7g)生长的影响进行了研究。试验饲料中分别添加0.5%-2.0%的CaCO_3、2.0%的CaCl,·2H_2O、2.0%的CaHPO_4·2?..
Catgut Fetal growth The calcium source for growth To formulate the full-fledged compound feed, researchers at the University of Texas at Dallas studied the effects of calcium sources and different amounts of feed on the growth of channel catfish (1.7 g). 0.5% -2.0% CaCO 3, 2.0% CaCl 2 · 2H 2 O and 2.0% CaHPO 4 2 · 2 were added to the experimental diets respectively.
