Effect of Moringa oleifera mixed with Sorghum bicolor ×S.sudanese hybrids
Moringa oleifera is rich in protein,vitamins,mineral elements,and unsaturated fatty acids,whereas Sorghum bicolor × S.sudanese have a high sugar content and high biological yield.Both are nutrient-rich forage resources.In this study,M.oleifera leaves(Y),M.oleifera branches(Z),and M.oleifera branches and leaves(ZY)were mixed with Sorghum bicolor × S.sudanese(G)in the following six proportions:0,20％,40％,60％,80％,and 100％.After 40 days of silage,the sensory quality(odor,color,texture),fermentation quality(organic acid content),and nutritional composition of crude protein,crude fiber(CF),ether extract(EE),nitrogen-free extract(NFE),neutral detergent fiber(NDF),acid detergent fiber,crude ash,and water-soluble carbohydrates of the silage forage were evaluated.The appropriate proportion of different M.oleifera tissue(Y,Z,ZY)and Sorghum bicolor × S.sudanese in mixed silage was explored.The results showed that single storage of Sorghum bicolor × S.sudanese was the best,followed by mixed storage of Sorghum bicolor × S.sudanese and M.oleifera leaves.Single storage of M.oleifera branches and leaves was the lowest.The CF and NDF contents were significantly decreased in the mixture of 80％M.oleifera leaves and 20％Sorghum bicolor × S.sudanese,and the CF and NFE contents were significantly decreased in the mixture of 40％M.oleifera branch and 60％Sorghum bicolor x S.sudanese.The CF content was significantly decreased,and EE content was significantly increased in the mixture of 60％M.oleifera branches and leaves and 40％Sorghum bicolor × S.sudanese.These results show that silage quality can be improved by mixing with Sorghum bicolor × S.sudanese.The optimal mixing ratio of M.oleifera leaves,branches,branches and leaves were 80％,40％,and 60％,respectively,with optimal results obtained for the 80％M.oleifera leaves and 20％Sorghum bicolor × S.sudanese mixture.This study provides a foundation for efficient utilization of M.oleifera and Sorghum bicolor × S.sudanese resources to facilitate sustainable development of ecological animal husbandry in Yunnan.
