| 摘 要： | 选择 96只 1日龄健康的罗曼商品蛋鸡 ,随机分成 4个组 ,分别饲喂含有效磷为 0 1 1 %、0 2 %、0 4 %和 0 6 %的日粮。试验 30天。结果表明 ,低磷、高磷日粮显著降低增重和耗料量 (P <0 0 5) ;低磷日粮 ( 0 1 1 % )可导致雏鸡磷缺乏症及高死亡率 ,以生长迟缓、胸骨弯曲为早期的临床指征 ;试验至 1 0天 ,2、3组ACP活性显著高于 1、4组 (P <0 0 5)。试验至 30天 ,低磷日粮显著降低血浆磷含量(P <0 0 5)。试验至 1 0、2 0天 ,低磷日粮显著降低胫骨磷含量 (P <0 0 5)。血浆、胫骨磷水平可作为雏鸡磷缺乏症的早期实验室诊断指标。低磷日粮显著降低肾脏和胫骨钙含量 (P <0 0 5) ,表明低磷日粮对钙的代谢有不利的影响

| Abstract: | Ninety-six commercial chicks were edivided into four grouprandomly,and fed the diets with 0.11%,0.2%,0.4%,0.6% available P,respectively.During a thirty-day experiment,the results indicated that the low-P and high-P diets decreased gain weight and feed consumptoin significantly (P<0.05).The low-P diets (available P:0.11%)could cause phosphorus deficiency and high mortality of chicks.The growth retardation and sternum bending were the earliest symptoms of phosphorus deficiency.The low-P diets decreased plasma ACP activity on day 10(P<0.05).The low-P diets decreased plasma phosphorus content sigificantly on day 30(P<0.05).Low-P diets decreased tibia phosphorus content on day10and day 20(P<0.05)。The results show the plasma and tibia phosphorus content have dignosis meaning in early stage of chicks phosphorus deficiency.Low-P diets decreased tibia and kidney calcium content significantly (P<0.05).These results suggest that the low-P diets have an adverse effect on calcium metabolism. |
