| 摘 要： | 对147—300日龄白来航型星杂288产蛋母鸡用三年时间进行了钙磷水平对蛋壳质量影响的试验。1982年饲粮钙水平为3.78、3.29、3.02％时蛋壳质量都在正常范围之内,但其质量随钙水平的增加而提高。1983年钙水平为3.8、3.3％,磷水平为0.6、0.4％,1984年重复1983年试验,结果表明,蛋壳质量均在正常范围之内,但高钙水平(3.8％)与低磷水平(0.4％)组蛋壳质量较好。从产蛋率看,三年试验均为钙水平3.3％、磷水平0.6％组为好。

The Relationship Between Diet Calcium Phosphorus Level and Egg Shell Quality |
| |
| Abstract: | The effects of calcium phosphorus levels on egg shell quality were experimented in white Leghorn type shaver-288 laying hen 147-300 days of age for three years. In 1982, when the diet calcium levels were 3.78, 3. 29, 3. 02%, the egg shell appeared to be normal. There was a good quality of egg shell with the increase of calcium level. Results obtained in 1983 and 1984 showed that egg shells were normal, when the diet level of calcium: phosphorus was 3,8%: 0.6% and 3.8%: 0.4% respectively. High calcium level (3.8%) and lower phosphorus level (0.4%) gave better quality of egg shell. With regard to the laying rate, the better nesults were obtained in a group to which the calcium and phosphorus were given at a level of 3.3% and 0.6% respectively, in a period of three years. |
