Effects of Two Enzyme Feed Additives on Digestion and Milk Production in Lactating Egyptian Buffaloes

Abstract The aim of this study was to evaluate the effect of two commercial enzyme products on milk production in Egyptian buffaloes. Twenty-one lactating buffaloes (570±15 kg BW) were divided into three groups (n=7) in a randomized block design for four months. Buffaloes were fed a total mixed ration containing 60% forage [rice straw and berseem hay (Trifolium alexandrinum)] and 40% concentrates with either no enzymes added (Control) or an addition of 40 g of Veta-Zyme Plus® (VET) or 40 g of Tomoko® (TOM ) enzyme product per day for each buffalo. Enzyme addition did not affect feed intake (P>0.05), but increased the digestibility of nutrients (P<0.05) and serum glucose concentration (P=0.011). Furthermore, the addition of VET increased milk (P=0.017) and fat corrected milk (P=0.021) yields, fat content (P=0.045), total unsaturated fatty acid (P=0.045) and total conjugated linoleic acid (P=0.031) contents in milk and decreased the content of total saturated fatty acids (P=0.046), while the addition of TOM increased milk total protein (P=0.023) and true protein (P=0.031) contents. The two enzyme products both resulted in higher concentrations of lysine (P=0.045) and total essential amino acids (P=0.036) in milk. It was concluded that addition of commercial fibrolytic enzyme products (i.e. Veta-Zyme Plus® and Tomoko®) to the diet of early lactating buffaloes enhanced nutrient digestibility and milk production and quality.
