Performance, Carcass Production, and Meat Quality of Sumba Ongole Bulls Fed Ration Supplemented Velvet Bean (Mucuna pruriens)
Abstract: This research aimed
to study performance, carcass production, meat quality, and economic
feasibility of male Sumba Ongole cattle fed ration supplemented with velvet
bean (M. pruriens). The research was designed in a completely randomized block
design using 16 cattle with average body weight of 488+37.08 kg. The treatments
were: T0= 15% straw + 85% concentrate; T1= T0 + 12% of velvet bean flour
supplement; T2= T0 + 16% of velvet bean tempeh supplement; and T3= T0 + 200
mg/head/d of ractopamine hydrocloride. Data were analyzed by using analysis of
variance with orthogonal contrast. The observed variables included feed
consumption, average daily body weight gain (ADG), feed efficiency (FE), income
over feed cost (IOFC), hot carcass weight (HCW), carcass percentage,
subcutaneous fat thickness, meat pH, tenderness, cooking loss, and water
holding capacity (WHC). The result revealed that the addition of 12% velvet
bean flour into the rations increased dry matter consumption (P<0.05), but
did not affect ADG, FE, IOFC, carcass production, and meat quality. The
addition of 12% velvet bean flour produced the lowest cooking loss (P<0.05).
The addition of 16% velvet bean tempeh into the rations significantly increased
(P<0.05) dry matter consumption, however reduced (P<0.05) ADG, FE, and
IOFC compared to control treatment. It is concluded that velvet bean flour at
the level of 12% can be used as an alternative feed supplement in the ration of
Sumba Ongole cattle and can replace the use of synthetic ß-agonist.
