Abstract:
A research was designed to examine the effect of methanolic extract of Moringa oleifera on growth performance, digestibility and immunity in quails. A total 180 day-old quail chicks were divided into four treatment groups; MOLE-0, MOLE-1, MOLE-2, and MOLE-3. Each group was separated into three replicates, and each replicate contained 15 chicks, which were kept until day 42 of age. In groups MOLE-1, MOLE-2, and MOLE-3, 100, 200, and 300 mg/L of methanolic extract of Moringa oleifera leaves (MOLE) were added, accordingly. Group MOLE-0 was kept as control group. In accordance with guidelines, all chicks received vaccinations against infectious bronchitis (IB), Newcastle disease virus (NDV), and infectious bursal disease virus (IBDV). Fresh water and feed were readily available to the chicks. Feed intake (FI) and mortality were noted daily. Body weight (BW) and feed conversion ratio (FCR) was noted weekly. Immune organ index, dressing percentage (DP) and fecal collection for digestibility analysis was done at 42 days of age. Using the common HA and HI technique, the antibody titer against the New Castle virus was calculated. At the end of experiment, the collected data was statistically analyzed. FI was not influenced (P>0.05) by supplementation of MOLE. Group MOLE3 had substantially higher BWG, FCR, and DP (P<0.05), followed by MOLE-2, MOLE-1, and MOLE-0. There was no variation in mortality (P>0.05) among the treatment groups. Weights of the spleen, thymus, and bursa were lower in the control group and considerably greater (P<0.05) in MOLE-3 than in other treatment groups. The treatment groups' improvements in antibody titre against Newcastle disease (ND) were statistically significant (P<0.05). Significantly higher antibody titre against ND was recorded for MOLE-3 and lower in MOLE-0 while antibody titre against ND was statistically same in MOLE-1 and MOLE-2. Moringa extract at 300mg/litre in drinking water had a considerable (P<0.05) impact on digestibility of DM (dry matter) and CP (crude protiens) while of ash, crude fibre and ether extract was not influenced by supplementation of MOLE. In conclusion, data of the current trial indicated that methanolic extract of M. oleifera leaves at the level of 300mg/litre in drinking water had improved growth performance, digestibility of DM and CP and immune status of quail's chicks
