| Abstract: | The apparent digestibilities of Ca and P in different physiological stages of Holstein dairy cows were measured in the experiment.The results indicated that:the apparent digestibilities of calcium and phosphorus were significantly affected by different growing period(P < 0.05).The apparent digestibilities of Ca at the 12 and 24 month-old were significantly higher than that of 18 month-old(P < 0.05),the apparent digestibilities of P 12 and 24 month-old cows were significantly higher than that of 18 month-old... |
