Influence of Moringa Oleifera Leaf Meal Used as Phytogenic Feed Additive on the Serum Metabolites and Egg Bioactive Compounds in Commercial Layers

Abstract

Phytogenic feed additives have been increasingly used in the last decade, and several plants and their metabolites have been investigated for the said purpose. In this context, present study aimed at evaluating the effects of Moringa oleifera as feed additive on layer performance, and egg bioactive compound levels and nutrient profile. HyLine W36 layers (n=200), 50 weeks of age, were randomly distributed in four treatments with five replicates of ten birds each. Four isocaloric (2725 kcal/kg) and isonitrogenous (CP 16%) diets were formulated and supplemented with 0, 0.5, 1.0, or 1.5% (w/w) of dried Moringa oleifera leaf powder (MLM). The results showed positive effects of MLM on egg production, egg mass, and feed conversion ratio, but negative effects on egg quality (p≤0.05). The contents of bioactive compounds, like β-carotene, quercetin, and selenium, in the diet and in the egg yolk were significantly (p≤0.05) higher in the group fed1.5% MLM, with values of 8.90, 48.88, and 0.54 mg/kg feed and 4906, 241 and 56.82 µg/100g yolk, respectively. Creatinine and glucose serum levels and cholesterol levels (serum and eggs) linearly increased as a function of increasing MLM dietary levels (p≤0.05). Antibody titers against Newcastle Disease significantly improved (p≤0.05) in the group fed the diet supplemented with 1.5% MLM. It was concluded that Moringa oleifera used as phytogenic feed additive enriches eggs with bioactive and functional compounds, and improves the production performance and the health status of layers.

The effect of dietary supplementation of mucuna leaf meal on the growth performance, blood parameters, and carcass quality of broiler

“…The performance parameters such as body weight gain, feed conversion ratio, and broiler chickens' livability are affected by nutrition (Martins et al, 2016). The observed better growth performance recorded in birds fed diet 5 may be due to activities of the bioactive components of MLM which supports better growth performance by improving the food status (Ahmad et al, 2018), by producing anti-microbial, antioxidant and flavour enhancer effects (Valenzuela-Grijalva, Pinelli-Saavedra, Muhlia-Almazan, Domínguez-Diaz, & González-Ríos, 2017).…”

Addition of binahong (Anredera cordifolia) leaf powder to diets to produce eggs with low cholesterol

“…Iskender et al [16] reported that supplementation with flavonoids (hesperidin, naringin, and quercetin) increases egg protein. Ahmad et al [37] documented that bioactive compounds from Moringa oleifera leaf extracts increase the protein content in yolk.…”
