NUTRITIVE VALUE OF WHITE KAURA SORGHUM (SORGHUM BICOLOR L.Moench) GRAINS AND SPROUTS AND THEIR UTILIZATION BY GOATS

Abstract:

Trials were conducted to determine the nutrient profile of hydroponic white kaura sorghum sprouts as compared to the grains and the performance of Red Sokoto goats fed the experimental diets. The measurement of the animal response at experimental level was performed in order to test the hypothesis that sprouting gives rise to hydroponic sprouts that give higher animal performance. In the first part of the experiment, white kaura sorghum was sprouted hydroponically for 7 days duration. Daily sampling of the sprouts was done to determine the dry matter (DM) concentration and also to determine the nutrient concentration on day 7 in comparison to the unsprouted grain. The result shows a 24.6% loss (P<0.05) in DM from the seed after sprouting for a period of 7 days. The CP, ash and lipid (4.9, 1.12, 2.15%) respectively, were higher (P<0.05) in concentration in sorghum sprouts than in the sorghum grains on a DM basis. This was considered to be a reflection of a loss in DM after sprouting, causing a change or shift in concentration of these nutrients. The level of vitamin A, C and E (10.00, 12.10, and 0.45) respectively, were higher (P<0.05) in concentration for the sprouts than the grains. The level of Nitrogen intake, Nitrogen absorbed and total nitrogen loss (24.24, 19.43 and 4.82) were lower (P>0.05) in sprouted when compared to the grains. The second phase of the experiment involved feeding of hydroponic white kaura sorghum sprouts and the grains to Red Sokoto goats. Ten Red Sokoto goats were randomly allocated to the two experimental diets in a completely Randomized Design. There was significant difference (P<0.05) in nutrient digestibility in grains compared with hydroponic sorghum sprouts. The level of crude fibre, ether extract and organic matter were (26.10, 6.18, and 44.73) respectively, were also higher (P<0.05) for the diet containing sprouted fodder when compared to the control diets, therefore there is advantage of fodder over the control diet. The level of Nitrogen ammonia (NH3-N), Total volatile fatty acid (TVFA) and the pH were significantly higher P<0.05 for the animals fed sprouted fodder diet when compared to the control diet (33.29, 20.91, and 6.50) respectively. It was then concluded that the 24.6% loss of DM followed 7 days of sprouting, however, did not allow the animals the chance to utilize such energy for useful purposes.
