An 8-week feeding trial was conducted to evaluate the effect of Moringa oleifera leaf meal (MOLM) on growth performance, antioxidant status and morphological indexes in Nile tilapia (Oreochromis niloticus). Resistance to Streptococcus agalactiae was also assessed based on a 192h challenge experiment after feeding trial. Fish (initial mean weight 4.05±0.05g) were held in 21 tanks (volume 300L, 30 fish/tank), with triplicate treatment groups being fed to apparent satiation three times each day on practical diets adding different levels of MOLM (0, 0.1, 0.5, 2, 5, 10 and 20%). Sampling procedure was performed after 24h of fasting. Growth metrics showed no significant differences among groups. Whole-body lipid content, viscerosomatic index and intraperitoneal fat ratio were decreased as dietary MOLM levels increasing. Total superoxide dismutase (T-SOD) and reduced glutathione content (GSH) were significantly influenced by MOLM. Moreover, the lowest cumulative mortality rate (CMR) after challenge experiment was noted in 10% group. Based on CMR and quadratic regression analysis of liver GSH content, it was concluded that dietary MOLM levels of 8.15-10.00% may be beneficial for enhancing resistance to S. agalactiae infection. Our results suggest that the maximum additive amount of MOLM reached 20% under the condition of the present study.

Background: Moringa (Moringa oleifera) is a highly valued plant grown in tropical and subtropical countries. Moringa has a high amount of crude protein, a well-balanced amino acid profile, vitamins and minerals and fewer quantities of antinutritive factors. Methods: Eighteen growing Deccani lambs of uniform body weight (14.22±1.5 kg) and age were randomly allotted to three treatment groups viz., 100 per cent groundnut cake (T1), 75% groundnut cake+ 25% Moringa oliefera leaf meal (T2) and 50% groundnut cake+ 50% M. oliefera leaf meal (T3) as a protein source in the concentrate mixture. The experiment was conducted for 90 days. Result: No significant difference was found in the fortnightly body weights of the lambs from 1st to 6th fortnights among three dietary groups. Total weight gain and Average Daily gain (ADG) were significant (P less than 0.01) among the treatment groups whereas DMI (kg/day), per 100 kg and FCR was non-significant. The digestibility coefficients (%) of all nutrients were non-significant (P greater than 0.05) except the NFE. Pre-slaughter weight, empty body weight, hot carcass weights and dressing percent on pre-slaughter weight and empty body weight were comparable among the three groups. Results of the present study indicated that inclusion of 25% Moringa oleifera leaf meal in concentrate mixture proved to be superior and improved the growth performance, digestibility of nutrients and carcass traits without any adverse effects on experimental lambs.
