Growth Performance and Physiological Responses of Garut Lambs Fed Diets Mung Bean Sprout Waste at Different Times

Abstract: This study evaluated the effect of a diet containing mung bean sprout waste (MBSW) as a fiber source and feeding time on the growth performance and physiological responses of Garut lambs. Feeding regimens generated by a factorial randomized block design with two factors- diet and feeding time-were assigned to twenty Garut male lambs aged 6-7 months (BW 15.42±2.42 kg). The two diets (D) formulated with a dry matter (DM) base were D1 (60% concentrate 1+40% natural grass) and D2 (60% concentrate 2+40% MBSW). Feeding times were in the morning (MF, 6:00-7:00 am) or the evening (EF, 5:00-6:00 pm). The animals were reared in individual cages and fed with 5% DM/kg body weight/day. Nutrient intake (DM, crude protein (CP), total digestible nutrient (TDN) and average daily gain (ADG) of lambs fed D2 was significantly (p<0.01) higher than that of lambs fed D1. The feed conversion ratio (FCR) of lambs fed with D2 at the EF feeding time was significantly improved (6.07, p<0.05) compared to lambs fed D1 at the MF and EF time, respectively (7.88 and 8.27), or lambs fed D2 at the MF time (7.84). Heart rates (HR) were higher in lambs fed D2 than lambs fed D1. In contrast, the respiration rate (RR) and rectal temperature (RT) were similar for all treatments. These results suggest that diets containing 40% MBSW as a fiber source together with an evening feeding time could increase growth performance while preserving normal physiological responses of Garut lambs.
