Résumé
A study was conducted in two stages to evaluate the efficiency of Moringa oleifera leaves as a non conventional feed resource in animal feeding system. In first phase of the study in vitro experiment was carried out on six treatment groups of ground nut straw based complete feeds containing Moringa oleifera leaves at the level of 0, 3, 6, 9, 12 and 15% of complete feed respectively in place of equal proporations of cotton seed cake to determine optimum level of incorporation of Moringa oleifera leaves in the complete feed. On the basis of results obtained by in vitro study, in vivo studies consisted of a digestion trial of 90 days followed by a metabolic trial of 7 days were conducted on 12 male Marwari goat kids, distributed in to two groups control (T0) and treatment (T1). The in vitro analysis of complete feeds revealed that the feed containing 15% levels of Moringa oleifera leaves had significantly (p<0.01) higher values IVDMD, IVOMD and IVTGP thus it was selected for in vivo experiment. The observations recorded in the second phase of the study indicated that supplementation of Moringa oleifera leaves in the diet of experimental goat kids at the level of 15% of complete feed significantly (p<0.05) improved total weight gain, average daily weight gain and digestibility of dry matter and crude protein. No significant difference was observed in the values of body measurement, dry matter intake, organic matter intake and feed conversion ratio of kids between the groups. Significantly (p<0.01) improved values of DCP, TDN, nutritive ratio, nitrogen and minerals (calcium, phosphorus) balance were observed in T1 group in comparision to T0 group. The analysis of rumen fluid collected by experimental goat kids at different time interval post feeding suggested that supplementation of Moringa oleifera leaves in the diet of experimental goats significantly increased (p<0.01) total VFA concentration, rumen total nitrogen and TCA precipitable nitrogen content while rumen pH and ammonia nitrogen content were significantly (p<0.01) reduced on Moringa oleifera leaves supplementation in diet. The study of haemato-biochemical parameters of experimental goat kids revealed that there was no significant difference in the values of total serum proten, glucose, ALT, AST and BUN levels between control and treatment group. Contemplating the findings of present study it could be concluded that supplementation of Moringa oleifera leaves in the diet at 15% level in place of one of the protein source could improve growth performance and nutrient utilization in goats without any adverse effect in rumen and haemato-bioochemical parameters. Thus it could be used as a beneficial approach for improving animal production and reducing feed cost.
