Abstract

Two separate experiments were conducted to compare the nutrient digestion and growth performance of beef cattle fed diets containing up to 77% of two conserved alfalfa hays. The two alfalfa hays were baled either at the optimum moisture (8.6%) or at a higher-than optimum moisture (21.4%) with application of a mixture of Pediococcus pentosaceus and chitinase at baling. Digestibility of dry matter, neutral detergent fibre, acid detergent fibre, rumen parameters, and growth performance were similar (P ≥ 0.16) for cattle fed either diet. A combination of P. pentosaceus and chitinase has the potential to preserve high-moisture alfalfa hay.
