Abstract


Adult male buffaloes (20) weighting 480.2 ± 7.99 kg were divided into 5 groups of 4 animals in each following a completely randomized design to determine the metabolizable energy content of 4 cereal grains. The animal sin control group (T1) were offered a basal diet composed of 700g deolied groundnut-cake and ad lib. wheat straw, whearas test groups were offered 1.8 kg broken grains viz, wheat (T2) sorghum (T3), bajra (Penesetum typhoid) (T4) or rice kani (T5) each along with the basa diet. The dry matter intake was 60.6 ± 2.62, 71.3 ± 3.58, 70.1 ± 6.00, 72 ± 2.14 and 71.0 ± 2.32 g/kg W0.75 /d in T1, T2, T3, T4 and T5 groups respectively. Dry matter intake was significantly (P<0.05) higher in T2, T3, T4, and T5 groups than T1 group. Dry matter digestibility was 50.2 ± 1.32, 57.1 ± 1.91, 54.2 ± 2.10, 56.3 ± 1.18 and 56.2 ± 1.06% in T1, T2, T3, T4, and T5 groups respectively, without any significant difference with each other. The gross energy intake was 262 ± 11.2, 3.11 ± 15.5, 306 ± 25.8, 316 ± 9.2 and 306 ± 10.0 and metabolizable energy intake was 104 ± 5.4, 146 ± 4.4, 138 ± 10.0, 138 ± 7.8 and  136 ± 6.1 keal/kg W0.75/d in T1, T2, T3, T4 and T5 groups respectively. Methae production was 145.6 ± 9.98, 195.0 ± 3.94, 198 ± 8.32, 195 ± 7.64 and 173.3 ± 8.44 I/d in T1, T2, T3, T4 and T5 groups resectively. Methane production was significantly (P<0.05) higher in T2, T3, T4 and T5 groups than T1 However, variation among test groups was not significant. Energy balance was 0.2 ± 1.3, 33 ± 4.8, 7± 2.8, 2.6 and 18.0 ± 4.01 keal/kg W0.75/d in T1, T2, T3, T4 and T5/sub> groups respectively. The digestible energy content was 3.71 ± 0 17.3.26 ± 0.28, 2.98 ±  0.31 and 3.00 ±  0.21 and metabolizable engery content was 3.26 ± 0.13, 2.77 ± 0.33, 2.56 ± 0.36 and 2.76 ± 0.25 Mcal/kg dry matter for wheat, sorghm, bajra and rive kani (broken rice), respectively, differences between grains being nonsignigicant.
