Abstract
The study entitled “Performance of Indigenous Cows on Supplementation of Different Mineral Mixture In Challenge Feeding” was conducted for 60 days pre-partum and 60 days postpartum. Eighteen advance pregnant indigenous 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 1 kg of concentrate for maintenance per day from 60th day to prior to calving till the day of parturition. T2 group animals were fed 1 kg concentrate for maintenance plus 1.5 kg concentrate as challenge feed per day plus 30 gm non-chelated mineral mixture from60th 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 plus 30 gm non-chelated mineral mixture as challenge feed per day. T3 group animals were fed 1 kg concentrate for maintenance plus 2 kg concentrate plus 30 gm chelated mineral mixture 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 2.5 kg concentrate plus 30 gm chelated mineral mixture as challenge feed 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. The average DMI (kg) in T1, T2 and T3 cows during pre-partum period was 8.20, 10.10 and 11.20 kg respectively which did significantly between treatments. The postpartum DMI was significantly higher (P<0.05) in T3(11.00 kg) as compared to T2(9.40 kg) and T1 (8.30 kg) respectively. The overall mean daily milk yield per animal was significantly higher (P<0.05) in T3 (4.42, 4.15, 9.93 & 9.68 kg) as compared to T2 (4.18, 3.66, 9.33 & 9.23 kg) & T1 (2.84, 2.98, 6.62& 6.50 kg) in Gaolao, Red kandhari, Gir and Sahiwal, respectively. The difference in mean calf birth weight T1, T2 and T3 was 20.3, 23.2 and 24.43 kg, respectively. The mean daily colostrum yield T1, T2 and T3 was 2.74, 3.14, 3.66 kg and 2.78, 3.26, 3.90 kg and 6.30, 8.44, 9.52 kg and 6.20, 8.26, 8.90 in gaolao, red kandhari, gir and sahiwal, respectively. Number of days taken to achieve peak yield T1, T2 and T3 was 42.50, 53.66 and 57 days and T1 groups achieve earlier as compare to T2 and T3 and were significant. The differences in mean fat, SNF, lactose and total solid were significant effect and protein was found in non-significant effect. The cost of milk production for indigenous milch cow (Gir) was Rs. 14.50, 16.02 and 16.66 per liter and (Sahiwal) was Rs. 14.15, 15.76 and 16.68 per liter in T1, T2 and T3 group, respectively. Further it was noted that total income was increased as Rs 12114, 15573, 16035 and Rs12030, 15543 and 15600/- in T1, T2 and T3 groups of Gir and Sahiwal cows, respectively. It was concluded that the practice of challenge feeding of indigenous milch cows improved the production performance during early lactation without affecting their per parturient health and was found to be economical.
Description
The present investigation was undertaken during the year 2018-19 with three treatments and six replication. The purpose of present investigation was to improved the production performance and calf birth weight during early lactation without affecting their peri-parturient health and calf birth weight and increases the average milk production in indigenous cows.
