Abstract
All nutrients digestibility were significantly increased by the addition of the different levels of dried Moringa oleifera leaves (MOL), except the crude protein digestibility which insignificantly increased than those fed the control diet (C).
2. There are significant differces in the nutritive alues (TDN) between the control and the experimental groups. M3 Significantly (P≤0.01) highest TDN (66.67) followed by those fed diets M2 and M1 (65.41 and 63.61) with 10.75, 8.66 and 5.67% higher than those fed the control diet (C). The DCP was insignificantly increased by feeding dried Moringa oleifera leaves (MOL) diets.
3. All nitrogen utilization factors were significantly affected by the addition of dried Moringa oleifera leaves (MOL) in the rabbit diets except the N-absorbed. Feed intake (FI) and nitrogen intake (NI) were significantly (P≤0.01) higher in rabbits fed the control diet (C) than those fed diets supplemented with dried Moringa oleifera leaves (MOL). Moreover, feeding rabbits with Moringa diets (M1, M2 and M3) significantly (P≤0.01) decreased the fecal nitrogen (FN) by 11.98, 15.99 and 21.09%, respectively, and urinary nitrogen (UN) by 8.64, 10.92 and 23.28%, respectively, than those fed the control diet (C). On the other hand, the results showed that the supplementation rabbit diets with dried Moringa oleifera leaves (MOL) (groups M1 and M2) insignificantly increased the absorbed nitrogen (AN) Summary & Conclusion 2021 142 than those fed the control diet (C). The nitrogen balance (g/day) was significantly (P≤0.01) increased in groups fed diets M2 and M3 than the other experimental groups. The nitrogen balance (NB) was significantly (P≤0.01) increased in groups fed diets M2 and M3 by 20.51 and 27.35%, respectively, than those fed the control diet (C). Moreover, the highest NB/NI% and NB/AN% were significantly (P≤0.01) obtained in group fed diet M3 with 37.03 and 27.98%, increments, followed by those fed diet M2 with 24.33 and 17.14% increments, respectively, than those fed the control diet. On the other hand, the NB (g/day), NB/NI% and NB/NA% were insignificantly differed between groups fed the control diet and those fed diet M1.
