Abstract
The aim of present study was to find out the performance of crossbred cows on supplementation of different mineral mixture in challenge feeding. Eighteen advance pregnant crossbred cows were selected 60 days before expected date of calving and were divided into 3 groups i.e. control (T1), treatment (T2) and (T3) on the basis of milk yield, parity and body weight for this study. During the pre-partum period, animals of T1 control group were fed 1kg concentrate for maintenance per day from 60th day to prior to calving till the day of parturition. T2 group animals were fed 1kg concentrate for maintenance plus 1.5 kg concentrate as challenge feed per day from 60th day to 22nd day prior to calving and from 22nd day prior to calving till parturition animals were fed 1 kg concentrate for maintenance plus 2 kg concentrate as challenge feed plus 30 gm non-chelated mineral mixture per day. T3 group animals fed 1kg concentrate for maintenance plus 1.5 kg concentrate as challenge feed per day from 60th day to 22nd prior to calving and from 22nd prior to calving till parturition animals were fed 1 kg concentrate for maintenance plus 2.0 kg concentrate as challenge feed plus 30 gm chelated mineral mixture per day. During the postpartum period, animals of T1, T2 and T3 group were fed based on their milk yield as per thumb rule i.e. 1 kg concentrate per day for maintenance and 1 kg concentrate per 2.5 kg of milk production plus T2 group animal fed 30 gm non- chelated mineral mixture and T3 group fed 30 gm chelated mineral mixture.
The mean DMI (kg) in T1, T2 and T3 cows during pre-partum period was 8.02, 9.16 and 9.33 kg respectively which did significantly between treatments. The postpartum DMI was significantly higher (P<0.05) in T3 (10.61) as comapared to T2 (10.27) and T1 (9.75) treatments.
The overall mean daily milk yield per animal was significantly higher (P<0.05) in T3 (10.45) as compared to T2(8.75) & T1 (7.11). The difference in mean calf birth weight T1, T2 and T3 was 20.30, 23.57 & 24.53 kg respectively. The mean daily colostrum yield T1, T2 and T3 was 5.32, 7.04 & 7.82 kg respectively. Number of day taken to achieve peak yield T1, T2 and T3 was 39.00, 49.33 & 53.66 days and T1 group achieve earlier as compare to T2 and T3 and were significant.
The differences in fat, SNF, lactose and total solid were significant effect and protein was found in non-significant effect. The cost of per litre millk production was Rs. 28.10, 24.85 and 24.49 in T1, T2 and T3 group respectively. It was concluded that the practice of challenge feeding of crossbred cows improved the production performance duringearly lactation without affecting their periparturient health and was found to be economical.
