| 摘 要： | 试验选取5种磷酸盐,即磷酸二氢钙、磷酸氢钙、磷酸钙、磷酸一二钙、骨粉,选择50 g左右的建鲤为研究对象,随机分成6个处理,每个处理4个重复,每重复12尾鲤鱼。5个处理分别在基础饲料的基础上添加NPP含量为0.3%的磷酸二氢钙、磷酸氢钙、磷酸钙、磷酸一二钙、骨粉,其他条件一致。在试验进行的20 d,采用自动虹吸法收集粪便,进行表观消化率的分析。研究结果表明,鲤鱼对不同磷源磷的表观消化率存在显著差异(P<0.05)。磷酸二氢钙的表观消化率最高,在5种磷源中,其是最高效、经济的磷源。

| Abstract: | Five kinds of phosphates were used, monoealeium phosphate, diealeium phosphate,triealeium phosphate,mixture of monocalcium phosphate and dicalcium phosphate,bone meal. The 288 carp in the same size were allotted into 6 groups. All those phosphates were added to the basal diet to supply 0.3% of NPP. Each of the test diets was fed to 4 pens of 12 carps each, and one group were fed the basal diet without adding phosphate. All the tested diets had the same composition as that of the basic diet except phosphate. The carp was fed with the diets for 20 days, then the AD of phosphates were determined. The results showed that the AD of different phosphate were significantly different and the monocalcium phosphate is the effective and economical phosphorus source. |
