Feed characteristics and utilization of Moso-bamboo (Phyllostachys pubescens) pellet mixed with soybean curd residue and soy sauce cake for dairy cows.

摘要

The objective of this study was to evaluate the feasibility of replacing alfalfa hay cubes (AC) with pellets consisted of 50% moso-bamboo trunks and leaves, 40% soybean curd residue and 10% soy sauce cake on a DM basis (BSSP). The crude protein of BSSP was similar to AC, but the ether extract of BSSP was higher than that of AC. In order to clarify the digestibility and nutritive value of BSSP, three goats were fed diets consisting of 35% BSSP and 65% AC on a DM basis or AC only. The estimated total digestible nutrient of BSSP was 59.7% on a DM basis. In a palatability test using 21 dairy cows, BSSP showed superior palatability to the pellets consisted of moso-bamboo only (P<0.05). In feeding trial using four lactating dairy cows, no significant difference was observed in DM intake, milk production and plasma metabolites between the diets containing 10% BSSP or AC. These results indicate that BSSP can replace AC as 10% of the diet of lactating dairy cows.
