摘要
植源磷酸氢钙是一种新型的饲料添加剂。为研究其对肉鸡血清钙磷沉积和骨骼发育的影响，探讨这种新型磷添加剂的应用效果，为广泛应用此添加剂提供参考。试验选择刚出壳的健康AA肉仔鸡180只，分为Ⅰ、Ⅱ、Ⅲ、Ⅳ4个处理组。结果表明：各处理组血磷含量保持在1．6～2．7mmol／L、血钙含量维持在2．2-2．9mmol／L，碱性磷酸酶活性与血清钙磷含量没有直接关系；Ⅰ组血清中碱性磷酸酶活性的均值最高为1718．20U／L，Ⅲ组的最低为931．67U／L；Ⅰ组血磷含量比Ⅱ、Ⅲ、Ⅳ3组高17．33％、17．91％和20．92％（P〈0．05），Ⅰ组血钙含量显著高于Ⅲ组8．56％（P〈0．05）；Ⅰ组骨骼发育最差，胫骨重量和长度均显著低于其余3个处理组；Ⅲ组胫骨长度显著高于Ⅱ组（P〈0．05）；Ⅲ组骨磷百分含量较Ⅰ组显著高11．89％（P〈0．05）；Ⅲ、Ⅳ组骨钙百分含量与Ⅰ组相比差异显著，分别比Ⅰ组提高了12．88％和11．77％（P〈0．05）。
Dibasic calcium phosphate from plant sources is a new type of feed additives. An experiment was conducted to study the effects of feed-grade dibasic calcium phosphate from plant sources on serum deposition of calcium and phosphorus and bone growth of broilers. And the applying effects of this new additive of phosphorus were explored to provide suggestions which could be widely used. 180 newborn healthy broiler chickens of Arbor Acres were selected, and divided into Ⅰ, Ⅱ, Ⅲ and Ⅳ treatment groups with a random strategy. The results showed that each treatment group blood phosphorus content kept in 1.6-2.7 retool/L, and blood calcium content maintained in 2.2-2.9 mmol/L, the alkaline phosphate activity and serum calcium phosphorus content had no directly relationship; serum in the alkaline phosphate enzyme activity of group Ⅰ was value supreme 1 718.20 U/L, group III＇ s was minimum 931.67 U/L; the blood phosphorus content in group Ⅰ was higher than that in Ⅱ, Ⅲ, and Ⅳ group 17.33%, 17.91% and 20.92% （P〈0.05）, Blood calcium content in group Ⅰ was higher than that in group Ⅲ, be 8.56% （P〈0.05）; tibia weight and length in group I lower than those in ther were significantly below remaining 3 groups; tibia length in group III was higher than that group Ⅱ （P〈0.05）; bone phosphorus content in group Ⅲ was higher than that group Ⅰ by 11.89% （P〈0.05）; bone calcium content in group Ⅲ and group Ⅳ was higher than that group Ⅰ to by 12.88% and 11.77% （P〈0.05）.
