Blood chemistry, milk yield and composition, and milk fatty acids profile of lactating Anglo-Nubian goats fed Moringa oleifera leaf as a protein source.

Low availability and increased price of protein sources are a serious problem for animal producers. Therefore there is a need to find alternative ingredients for protein sources. Moringa oleifera leaf contains about 25% crude protein (CP) with low degradability, which make it a good source of protein in ruminant diets. In a 4 × 4 Latin square design, 16 lactating Anglo-Nubian goats (36.2 ± 0.7 kg BW) were used to evaluate the effect of replacing sesame meal (259.0 g CP/kg DM; 279.1 g neutral detergent fiber (NDF)/kg DM) with M. oleifera (241.2 g CP/kg DM; 336.6 g NDF/kg DM) at 0% (control-M0), 50% (M50), 75% (M75) and100% (M100). The experimental period consisted of 17 d for adaptation + 5 d for milk yield and sampling. All goats were sampled for blood at the last day of the experimental period 4 h after morning feeding. Goats were hand milked daily at 0900 and 2100 h for determination of milk yield. There was no effect of treatment on serum total proteins, albumin, globulin, glucose, creatinine, and triglycerides concentrations, with quadratically increasing GOT and GPT concentrations (P < 0.05) and decreasing urea-N (linear, P = 0.0339; quadratic, P < 0.0001) and cholesterol (linear, P = 0.0009; quadratic, P < 0.0001) concentrations. Milk yield and energy corrected milk were linear increased (P < 0.001) when goats fed on Moringa vs. control. Milk yield was greatest for M75 which had also higher total solids, solids not fat, and lactose versus other treatments. Milk components yield were increased with goats fed Moringa compared with control (P < 0.01). Moringa treatments increased (P < 0.01) milk fat content from C14:1, C18:1n-9 trans, C18:1n-9 cis, C18:2 trans-10,cis-12, and C18:2 cis-9,trans-11 with decreased C16:0 concentrations. Moreover, decreased (P < 0.05) saturated with increased unsaturated fatty acids and conjugated linoleic acids (CLA) were obtained when goats fed Moringa diets vs. control. It could be concluded that replacing 75% of sesame meal with M. oleifera as a protein source increased milk yield with enhancing milk content of healthy fatty acids (CLA and n-3), without detrimental effects on animal performance.
