Ruminal degradability of dry matter and crude protein of agroindustry, fish and slaughterhouse byproducts in goats

Abstract

Caprines were used in a change-over design to evaluate dry matter (DM) and crude protein (CP) degradability of the following byproducts: soybean meal 1 (SM1), heat-processed soybean (HPS), cotton seed meal (CSM), meat and bone meal 1 (MBM1), meat and bone meal 2 (MBM 2), soybean meal 2 (SM2), fish meal (FM), babasu meal (BM), blood meal (BLM) and chicken viscera meal (CVM) through in situ nylon bag technique. Napier grass (Pennisetum purpureum Schum) was fed as the only roughage. Effective degradability of CP was 68.47% (SM1), 65.60% (SM2), 60.71% (CSM), 65.69% (HPM), 61.59% (MBM1) and 62.58% (MBM2), while effective degradability of DM was 75.48% (SM1), 73.05% (SM2), 52.39% (CSM), 70.38% (HPM), 44.45% (MBM1), 47.01% (MBM2), 48.43% (FM), 38% (BM), and 53.82% (CVM), considering 0.05/h turnover (r).
