    EFFECT OF FEDDING COMPLETE FEED BLOCK AND PROBIOTICS SUPPLEMENTATION ON THE PERFORMANCE OF KIDS
    (College of Veterinary Science Assam Agricultural University Khanapara, Guwahati-781022, 2017-01) Rabidas, Amit; Haque, Adib
    Twenty four weaned male 3 month old kids were randomly assigned to four groups of six kids each viz. Control (T0), (T1), (T2) and (T3) receiving 250gm concentrate along with ad lib green grass, 250 gm concentrate supplemented with probiotics and ad lib green grass, block alone and block supplemented with probiotics respectively. The average initial body weights were 5.25 ± 0.24, 5.76 ± 0.20, 5.52 ± 0.20 and 5.71 ± 0.24 kg for T0, T1, T2 and T3 groups respectively and the corresponding figures at the completion of 12th week were 7.67 ± 0.16, 8.39 ± 0.15, and 7.95 ± 0.22 and 8.51 ± 0.24 kg. Increase in body weights of the four groups, up to 4th week post weaning did not show any statistical difference. From 5th to 12th week, T1 and T3 groups showed significantly (P<0.01) higher weights than the T0 and T2 group. This may be attributed to weaning shock in the kids upto 4th week. The overall means of body weights were 6.34 ± 0.10, 6.94 ± 1.10, and 6.57 ± 0.09 and 7.01 ± 1.12 kg for T0, T1, T2 and T3 groups respectively. The total body weight gains for T0, T1, T2 and T3 groups as 2.42 ± 0.12, 2.63 ± 0.06, 2.43 ± 0.21 and 2.80 ± 0.01 kg respectively. The corresponding values for daily body weight gains were recorded as 0.026 ± 0.01, 0.029 ± 0.006, 0.027 ± 0.002 and 0.03 ± 0.0001 g. T1 and T3 showed significantly (P<0.01) higher body weight gains than T0 and T2. However, T2 did not exhibit any significant differences in weekly body weight gains with T0. The 12th week body weight gains were 0.251±0.004, 0.279±0.014, 0.263 ± 0.030 and 0.289 ± 0.021 kg for T0, T1, T2 and T3 respectively. From 5th to 12th week, T1 and T3 groups showed significantly (P<0.01) higher gains than the T0 and T2 group. The overall means of body weight gain were observed as 0.201 ± 0.003, 0.219 ± 0.003, 0.203 ± 0.005 and 0.232 ± 0.002 kg for T0, T1, T2 and T3 respectively. The Initial body length of T0, T1, T2 and T3 were recorded were 37.60 ± 0.91, 37.87 ± 0.81, and 37.69 ± 0.55 and 37.91 ± 0.89 cm respectively and the corresponding final values were 44.50 ± 0.17, 44.81 ± 0.51, and 44.77 ± 0.21 and 44.99 ± 0.56 cm. The overall means were 41.18 ± 0.67, 44.81 ± 0.61, and 44.77 ± 0.66 and 44.99 ± 0.62 cm for T0, T1, T2 and T3 respectively. Initial heights of T0, T1, T2 and T3 were 33.92±1.19, 34.17 ± 0.98, and 34.02 ±1.14 and 34.34 ± 1.04 cm respectively. The heights noted at 12th week were 36.27 ±1.19, 36.69 ± 0.86, 36.57 ± 0.96 and 36.70 ± 0.94 cm and the overall means were 35.21 ± 0.21, 35.44 ± 0.22, 35.36 ± 0.22 and 35.56 ± 0.22. Initial heart girth of T0, T1, T2 and T3 were 43.88 ± 1.48, 43.73 ± 0.83, 43.67 ± 1.42 and 43.93 ± 0.53 cm respectively and the values at 12th week were 46.26 ±1.48, 46.64 ± 0.82, 46.45 ± 1.14 and 46.85 ± 0.51 cm. The corresponding overall means were 45.14 ± 0.21, 45.50 ± 0.24, 45.32 ± 0.23 and 45.66 ± 0.24 cm. The 1st week feed consumption of T0, T1, T2 and T3 were 1.123 ± 0.14, 1.181 ± 0.22, 1.178 ± 0.19 and 1.194 ± 0.18 kg respectively and the corresponding values at 12th week were 2.874 ± 0.14, 3.091 ± 0.19, 2.901 ± 0.19 and 3.161 ± 0.19 kg. The total feed consumed was calculated as 23.742 ± 0.02, 25.886 ± 0.08, and 24.201 ± 0.02 and 26.629 ± 0.22 kg for T0, T1 T2 and T3 respectively. Initial feed conversion efficiency in T0, T1, T2 and T3 were 7.959±0.17, 7.801 ± 0.53, 7.853 ± 0.27 and 7.803 ± 0.24 respectively and the corresponding values at 12th week were 11.45 ± 0.17, 11.031 ± 0.53, 11.078 ± 0.22 and 10.937 ± 0.24. The overall feed conversion efficiency was 9.724 ± 0.03, 9.396 ± 0.11, 9.565 ± 0.09 and 9.297 ± 0.05 for T0, T1 T2 and T3 respectively. Cost of feeding per kid in T0, T1, T2 and T3 was Rs. 456.065, 483.365, 483.365 and 491.48. Again, the costs of feeding per kg weight gain for the corresponding groups were Rs. 188.45, 183.78, 182.59, 175.52. The profit derived from T0, T1, T2 and T3 was Rs. 2343.94, 2816.64, 2656.30, and 3008.52. Supplementation of probiotics had a significant influence on the body weights and body weight gain and feeding of ration in the form of blocks resulted in apparent growth improvement which in turn could influence the goat production economy.
