Fermentation Characteristics and Nitrogen Retention of Madura Cattle Fed Complete Rations Containing Soybean Pod and By-Products
Abstract: This study was aimed
to evaluate the effect of complete rations containing soybean pod and soybean
by-products (soybean meal and tofu waste) on rumen microbial population,
fermentation characteristics, nutrient digestibility, and nitrogen retention of
Madura cattle. Twelve Madura cattle of 1.5 years of age were given 4 feeding
treatments in triplicates in randomized block design experiment. The treatments
included T0 (100% native grass) as a negative control, T1 (concentrate: grass
(60:40) as a positive control, T2 (complete ration containing 15% soybean
pods), and T3 (complete ration containing 30% soybean pods). The treatments
were based on feeding practices commonly applied by farmers in the village. The
results showed that the use of concentrate rations or complete rations
containing soybean pod and by-product did not affect protozoa population,
ammonia concentration, and total VFA production compared to cattle fed 100%
native grass. In contrast, the use of concentrate rations or complete rations
containing soybean pod and by-products reduced acetate and increased butyrate
proportion compared to native grass. The use of a concentrate ration resulted
the highest propionate proportion. Methane estimation increased with the use of
concentrate ration or complete ration containing 15% soybean pod, but it
decreased when the level of soybean pod was increased to 30%. It can be
concluded that soybean pod has a potential to be used as a fiber source in beef
cattle ration to substitute native grass.
