dc.description.abstractTwelve Mehsani buffaloes in their 2nd and 3rd lactation were selected to conduct on-farm trial at the Chikhodra village of Anand district for 120 days. The animals were selected on the basis of their average daily milk yield, fat % and body weight. The experiment was initiated on 15th day of lactation. The experimental animals were randomly allotted to two dietary treatments i.e. T1 (Control) and T2 (Bypass Fat) of six animals in each group, following Completely Randomized Design. All the experimental buffaloes were individually offered a basal diet of home- made concentrate mixture and wheat straw and paddy straw ad lib to meet their protein and energy needs for maintenance and for milk production as per NRC (2001). The commercial bypass fat supplement, Megalac, manufactured by M/s. Vetcare India Ltd., Bangalore, was provided to buffaloes in T2 group @ 200g/head/day. The experimental buffaloes produced on an average 9.52 ± 0.47 and 9.97 ± 0.34 kg whole milk/head/day, under T1 and T2 groups, respectively. The treatment groups differed significantly (P<0.05) from each other. The milk fat of experimental buffaloes in T1 and T2 groups was 6.39 ± 0.19 and 7.14 ± 0.19 %, respectively. The treatment groups differed (P<0.05) from each other. The TS and SNF % of milk was 15.82 ± 0.35, and 16.30 ± 0.27 and 9.43±0.19 and 9.15±0.13, respectively in T1 and T2 groups, which was statistically similar in both the groups. The daily yield of 6% FCM was 12.21±0.70 and 13.94±0.55 kg in T1 and T2 groups, which was significantly higher (P<0.05) in T2 as compared to T1 group. The dietary treatments were found statistically similar with respect to the digestibility coefficient (%) of OM, CP, CF and NFE. However, DM and EE digestibility was higher (P<0.05) in T2 as compared to T1 group. The CP and TDN content of composite diets in T1 and T2 groups was 10.22 ± 0.03 and 10.05 ± 0.01 and 56.57 ± 1.77, and 59.48 ± 0.76 %, respectively. The average daily CP and TDN intake as per cent of requirement (NRC, 2001) of experimental buffaloes were satisfactory during digestion trial conducted at the end of experiment. The FCE of buffaloes in T1 and T2 groups in terms of DMI (kg/kg milk) was 1.61 ± 0.04 and 1.50 ± 0.02 and in terms of CPI (g/kg milk) was 164.48+ 3.86 and 151.15± 2.26 in T1 and T2 groups, respectively, which was significantly higher (P<0.05) in T2 group. However, FCE in terms of TDNI (kg/kg milk) was did not differ statistically. The treatment groups T1 and T2 significantly differ (P<0.05) from each other with respect to the conversion efficiency of DM (1.55± 0.06, and 1.34 ± 0.05 kg), CP (158.16± 4.00, and 134.78± 2.91 g) and TDN (0.87 ± 0.02, and 0.80 ± 0.03 kg) into one kg 6% FCM. The service period of buffaloes was 118.33 ± 5.39 and 77.75 ± 7.09 days in Tj and T2 groups, respectively. The service period was lower by 40.58 days in T2 as compared to T1 group. The daily feed cost (Rs. /head) in T1 and T2 was 87.63 ± 3.17 and 95.34 ±1.87, respectively and was statistically higher (P<0.05) in T2 than T1 group. The data on daily realizable receipt from sale of milk (Rs/head) was 168.51 ± 12.6 and 197.04 ± 11.29 in T1 and T2 groups, respectively and the treatment groups differed (P<0.05) from each other. Accordingly, the daily return over feed cost (Rs./head) was 80.88 ± 7.27 and 101.71±6.50 in T1 and T2 groups, respectively. The same was significantly higher (P<0.05) in T2 as compared to T1 group. The improved reproductive performance on account of supplementation of bypass fat was exhibited in reduced service period in T2 (77.75 ± 7.09 days) as compared to T1 (118.33 + 5.39 days) The saving in feed cost (Rs./head) due to reduced service period (40.58 days) worked out as Rs. 3556.03 in T2 over that in control group. The net difference due to ROFC and due to improved service period put together worked out as Rs. 6055.21 in T2 group over control during experimental period of 120 days. These data indicate the importance of feeding bypass fat results in improvement in fat, total solids % (TS), yield of fat and 6% FCM, reproduction and net return from buffaloes during their early lactation.en_US
