Effects of different Ca and P levels in TMR on body measurements and weights,serum biochemical indicators of lactating donkey foals
Objective:To study the effect of different Ca and P levels in total mixed ration(TMR)on the body measurements and weights of the 4 month-age lactating donkey foals.Methods:The 40 healthy donkey foals(♂:22,♀:18)with 4 month-age,weight(39.66±6.17)kg were selected,randomly divided into 4 groups(10 each group,male and female half respectively)as a control group and 3 test groups,the control group fed by the TMR,the test groups added calcium hydrophosphate by 0.5%,1.0%and 1.2%respectively to the TMR as test group 1,2 and 3,then observing the effect of different Ca and P levels on body measurements and weights,serum biochemical indicator and blood cell changes of the foals.The results showed that,(1)The body measurements and weights of the foals in the test group 1,2 and 3 were all higher than that in the control group;(2)That in the test group 2 was greater than that in the test group 1,and there is statistically significant(P＜0.05);(3)That in the test group 3 was higher than that in the test group 2,but there is not statistically significant(P＞0.05).(4)Serum total protein,albumin,globulin,glucose and Lymph%from the test groups were significantly higher than those from the control group(P＜0.05).Conclusion:The Ca and P levels,added by 1%and 0.654%respectively to the TMR of the foals,are of benefit to growth of foals,meanwhile,improving the partial serum biochemical indicators and the immune levels of the foals.
