Abstract
The present study was divided into two parts. In the first part saponin and sapogenol content in mahuva seed cake was estimated and in the second part the feeding experiment on castrated buffalo bulls ( Surti ) to study the feasibility of using mahuva ( Madhuca indica, J.F.Gmel ) seed cake ( unprocessed ) in maintenance ration was carried out. Mahuva seed cake used for this experiment was estimated for saponin and sapogenol content. The result revealed that it contained 21.35 per cent saponin and 8.59 per cent sapogenol on dry matter basis. A 3 X 3 Latin square design with 8 weeks period was followed. The three treatments consisted of 0 (control), 25 and 50 per cent mahuva seed cake in concentrate mixtures and were designated as T1, T2 and T3 respectively. Each animal was fed daily with 2 kg of 'NB-21' green, mature pasture grass ad lib. and weighed quantities of concentrate mixtures ( pellet form ). The requirement of DCP and TDN were met as per Sen et al. (1978) feeding standard for maintenance. Feeding scheduled was changed for each animal with a change of period. The observation regarding weekly body weights for three consecutive days, dry matter intake, digestibility of proximate nutrients, balance of nitrogen, phosphorus and calcium changes in the different constituents in the blood (hemoglobin, total serum protein and serum phosphorus and calcium) and 2 hourly changes i n pH and nitrogen fractions (total nitrogen, non protein nitrogen and protein nitrogen) of the strained rumen liquor (SRL) were recorded. The results on body weight revealed that there was significant loss in weight in 25 per cent level mahuva seed cake fed group. This may be due to less retention of nitrogen and significantly less availability of digestible crude protein (DCP). The results on per cent dry matter intake and dry matter intake on metabolic body weight (g/kg W0.75) revealed that there was no significant difference between the treatments and hence these were not affected by incorporation of mahuva seed cake in the ration. The digestibility coefficients of crude protein, crude fibre, nitrogen free extract (NFE) and organic matter were slightly reduced but were found non significant. Thus, it is indicated that inclusion of mahuva seed cake upto 50 per cent level in the concentrate mixture did not affect the digestibility of proximate nutrients significantly except ether extract. The digestibility of ether extract was lowered significantly in 25 per cent level. Average balance of nitrogen, phosphorus and calcium were positive in the animals under all the treatments but retention of nitrogen and available DCP were significantly lower in 25 per cent mahuva seed cake fed group as compared to other two groups. Actual available TM was not affected significantly under all the treatments. Periodic changes in the blood constituents did not reveal significant changes i n hemoglobin, total serum protein, serum phosphorus and calcium content. Two hourly changes in ruminal (SRL) pH, total nitrogen, non protein nitrogen and protein nitrogen indicated no significant differences between the treatments except in protein nitrogen which continued to be synthesizes for longer period at higher concentration i n T1 ,as compared to mahuva seed cake fed groups ( T2 and T3). The cost of ration per day per, animal was worked out and was higher i n T1 ( 0 level, control) than T2 and T3 ( 25 and 50 per cent level). The maintenance cost was lowest in T3 (50 per cent level). However, the differences were statistically non significant. The cost of maintenance was reduced hy 5.1 and 9.1 per cent by the incorporation mahuva seed cake in the concentrate mixtures at the level of 25 and 50 per cent respectively.
