Moringa oleifera is considered as a miracle tree due to the presence of abundant nutrients, high protein biological value, and good feeding effects. As a new protein feedstuff, Moringa oleifera has great potential in alleviating the feeding crisis in animal feeding system. To explore the beneficial properties and practical utility of Moringa oleifera tree leaves, the present study had been performed on 12 male Marwari goat kids, randomly distributed in to two groups control and treatment. Kids were fed on ground nut straw based complete feed, whose composition was kept similar in both the groups except the incorporation of Moringa oleifera leaves in the diet of treatment group, at the level of 15% of complete feed as a replacement of equal proportions of cotton seed cake. A feeding trial of ninety days was conducted to observe the effect of supplementation of Moringa oleifera leaves on haematobiochemical parameters of experimental kids. Blood samples were collected at monthly intervals and analyzed by UV spectrophotometer. The study reported no significant difference of Moringa oleifera leaves supplementation on haemato-biochemical parameters of experimental kids. The study concluded that the Moringa oleifera leaves can be used in the diet of goats up to 15% level of incorporation.
