Provision of location-specific agricultural waste feed to Sumba Ongole cattle’s performance

Abstract

The study focuses on the feeding of by products on the performance of Sumba Ongole cattle. The byproduct is in the form of concentrate and originates from the site-specific agricultural leftover. The expected goal is that Sumba Ongole cattle can optimally achieve their genetic potential. The research location was in East Sumba Regency, East Nusa Tenggara Province, which is the source of local Ongole cattle. The study used 15 Sumba Ongole cows consisting of seven pregnant cows, four male calves, and four female calves. Basal feed uses rice straw, while the agricultural byproduct consists of several sources, rice bran, peanut straw, corn straw, corncob, leaves of river tamarind, leaves of Gliricidia sepium, and cassava. The results showed that the average change in body weight of broodstock cattle receiving concentrated treatment was higher than those that received bran. On an in-vitro basis, this is consistent with high crude fiber content (36%), low dry matter digestibility (25%), and low bran organic matter digestibility (27%). For the average weight gain in calves, the local concentrate treatment consistently shows crude protein as much as 12.1% compared to rice brand 5.6%. To improve the cattle’s productivity, giving the local-based concentrate is highly recommended, but the presence of rice bran still critical because of its ability to improve daily weight gain and also its high digestibility in dry matter, organic matter, and Total Digestible Nutrients.
