Impacts of Moringa oleifera Foliage Substituted for Concentrate Feed on Growth, Nutrient Digestibility, Hematological Attributes, and Blood Minerals of Growing Goats under Abu Dhabi Conditions

Abstract

To avoid the depletion and degradation of natural resources and to maintain long-term environmental quality and sustainability, the present study investigated the impacts of Moringa oleifera foliage (MF) as a replacement for concentrate feed on growth performance, blood hematology, serum metabolites, and serum mineral profile in growing goats. A total of 30 growing local goats (4 months old ± 7 days, with an average weight of 15.80 kg ± 147 g), were randomly allotted to five treatment groups comprising 0%, 25%, 50%, 75%, or 100% of MF replacing the concentrate feed as daily feed. The MF75 and MF100 percent diets decreased (p < 0.05) final body weight (FBW), average daily gain (ADG), and crude protein (CP) of the diet. Moreover, MF up to 75% improved acid detergent fiber (ADF) digestibility. Feeding MF at different levels did not have any deleterious effects on blood chemistry parameters. Urea, low-density lipoprotein (LDL), and alkaline phosphatase (ALP) values were depressed (p < 0.05), due to increasing the MF (MF50, MF75, and MF100) level in the diet of growing goats kept in an arid region, when compared to the control group. Both of MF75 and MF100 led to a decrease (p < 0.05) in phosphorous (P) level, compared with the other groups. The results were interpreted that feeding MF to replace 25% DM of the concentrate feed had no adverse effects on growth performance, feed utilization, serum metabolites, and serum minerals in growing goats reared under arid conditions. The increasing of MF level up to 50% or more significantly altered ADG and blood levels of creatinine, urea and ALP.

Influence of substituting soybean meal with moringa seed cake on feed intake, growth performance, digestibility, blood parameters and economics of fattening crossbred calves

“…Moringa seed cake has favorable effect on kidney function parameters by decreasing serum urea and creatinine concentrations. These results are in line with Aboamer et al ( 2020 ) and Zaher et al ( 2020 ), who mentioned that using MSC improves kidney function in ruminants. However, the decrease in urea and creatinine levels can be attributed to the protection of feed proteins from rumen degradation and improvement in protein digestion in the intestine (Aboamer et al 2020 ).…”

“…However, the decrease in urea and creatinine levels can be attributed to the protection of feed proteins from rumen degradation and improvement in protein digestion in the intestine (Aboamer et al 2020 ). The current results of liver enzymes (ALT and AST) were supported by Zaher et al ( 2020 ), who pointed out that MSC decreased serum ALT and AST concentrations because of its vitamin, flavonoid, glucosinolate, and phenolic acid contents. These components improve antioxidant and anti-inflammatory influences (Ndukaku et al 2015 ) and biological activities (Atta et al 2018 ).…”

“…The increasing in the hematological values in rations of MSC (25%, 50%, and 100 %) perhaps because the moringa contain a lot of vitamins especially vitamin C and minerals in particular iron, which promote the synthesis of Hb and amino acids, especially arginine, thereby improving immunity and lymphocyte proliferation (Faye et al 2011 ).In contrast, the results of protein fractions and glucose have been supported by previous studies (Aboamer et al 2020 ; Zaher et al 2020 ), who found that moringa enhanced serum TP, Alb, Glb, and Glu. The increasing in serum TP concentration in rations of MSC25% and MSC50% may be attributed either to the increase of CP digestibility (Kholif et al 2016 ) or the high level of protein, vitamins, minerals, and antioxidant components of moringa that decrease protein oxidation (Mohammed et al 2017 ).…”

“…Feces were collected from each animal, dried in the oven at 60°C for 24 h, and stored for laboratory analysis. The apparent coefficients of crude protein and acid detergent fiber digestibility were determined using a direct method ( 19 ).…”

Moringa oleifera leaf for replacing protein portion of soybean meal in the diet of young growing meat goats

“…White blood cells are a major component of the body's immune system (Ajith et al, 2017). Zaher et al (2020) reported, replacing daily concentrate feed with M. oleifera leaves to a level of 100% do not affect the blood hematologic profile of growing goats, although replacement starting at a level of 50% reduces feed intake.…”
