Abstract
The development of different innovative feed resources for livestock is important to provide the essential nutrients and diminish the emission of greenhouse gases. The purpose of the present experiment was to study the response of replacing concentrate with Moringa oleifera leaves in terms of the nutrient intake, digestibility, enteric methane emissions, and performance of goat kids with a berseem-fodder-based diet under different roughage (R)-to-concentrate (C) ratios. Twenty-four goat kids (3 months of age) were distributed into four groups of six animals each, using a randomized block design (RBD). Kids of Group I (control) were fed a basal diet with 70R:30C without any tree leaf supplementation. Group II kids were fed with 60R:40C, where 10% of the concentrate mix was replaced with Moringa leaf (ML powder). In Group III, kids were fed with 70R:30C with 20% ML replacement. In Group IV, kids were fed with 80R:20C with 20% ML replacement. A metabolic trial was conducted after 180 days of feeding to assess the impact of ML on blood metabolites, antioxidant status, immunity parameters, and enteric methane emissions. The results revealed that dry matter digestibility, organic matter, and NDF were better (p < 0.05) in ML-treated kids (GII and GIII) compared to GI. Feed conversion and average daily gain were also enhanced (p < 0.05) in the treated groups as compared to controls. Total blood protein and albumin were increased in GII and GIII kids compared to GI. Plasma cholesterol levels were decreased (p < 0.001) in GII, GIII, and GIV as compared to GI. Glutathione peroxidase, catalase, and superoxide dismutase enzyme activities were also enhanced in GII, GIII, and GIV compared to controls. ML supplementation improved cell-mediated immunity and humoral immunity responses in goat kids. Enteric methane emissions decreased in the treated groups as compared to the controls. Moringa oleifera leaf may be used up to the level of 10–20% in concentrate mixes to improve digestibility, blood biochemical parameters, immunity status, and antioxidant activity in goat kids. Supplementation of ML not only enhanced the digestion and health of goat kids, but also decreased their methane emissions.
