Effect of Different Dietary Levels on the Postpartum Reproductive Rerformance of Cross-Bred cows
The object of the present study was to asses the influence of higher dietary levels on the postpartum re productive performance of cross-bred cows. The meterials consisted of 30 crossbred cows in advanced stage of gestation. They were weighed on 270th day of gestation and on the day of calving and...

The meterials consisted of 30 crossbred cows in advanced stage of gestation. They were weighed on 270th day of gestation and on the day of calving and were randomly allotted to control, treatments 1st and 2nd . the control received ration based on Sen and Ray standard whereas, treatments 1 st and 2nd received 115 and 130 precent of control ration. The weight of the cows was recorded at 15 days interval from calving to oestrum.serum inorganic phosphorous, protein, glucose and haemoglobin percentage of 5 cows from each group was estimated. A decline of body weight wad observed in the first fortnight in all the three groups. This trend continued upto 30 days in the control whereas, in the treatment an increasing trend was observed from fifteenth day. Cows in all three groups showed postpartum oestrum, while there was in gain in body weight. The postpartum oestrous interval of control ,treatment 1st and treatment 2nd were 62.1+4.63, 56.60+5.53 and 53.22+3.75 days respectively and these values did not very significantly. However, postpartum oestrous interval of treatments 1st snd 2d was significantly less than that of the herd. Serum in organic phosphorous was significantly higher on the day of oestrum in control and treatment II. There was significant difference in serum protein values between groups at certain time intervals. It was also significantly more on the day of oestrum in both control and treatment I. Similarly blood glucose and haemoglobin were significantly higher on the day of oestrum in treatment I. Results of this study indicated that Sen and Ray ration is adequate to meet the requirement for both production and reproduction of cross- bred cows. | |
