Soybeans and meat-bone meal degradabilities, through nylon bags in situ technique, in dairy heifers and goats

AbstractGoats and heifers were used in a 3 x 3 change over design to evaluate the treatments: A) Meat and bone meal with 50% of CP (MBM 50), B) Meat and bone meal with 40% of CP (MBM 40), C) Soybean meal (SM). In situ nylon bag technique was used. Sugar cane was fed as the only roughage. Rates of disappearance of DM and CP were similar for goats and bovines
in all treatments. DM of MBM 40 and MBM 50 presented similar degradability rates, and both had minor degradability (p < 0.01) than SM beginning at 1.5 h incubation time. Effective degradability of DM was 77.4% (SM), 39.0% (MBM 40) and 39.0% (MBM 50). At incubation times 1.5 h, 3 h, 6 h and 12 h, MBM 50 had less protein degraded than MBM 40. SM had CP more degraded than MBM only at 12 h, 24 h and 48 h of incubation time (p < 0.05). Effective degradability of CP was 72.4% (SM), 54.4% (MBM 40) and 49,8% (MBM 50). It was concluded that both meat and bone meals can provide more undegraded
protein, related to soybean meal, after 12 hours of incubation time.
