EFFECT OF THE USE OF COOKING PRODUCT OF THE STEM CONTENT OF GEBANG (CORYPHA UTAN LAMK.) PLANT WITH UREA ON THE GROWTH OF BALI CATTLE

Abstract

The purpose of this study was to evaluate the impact of the use of slow release urea products from the cooking result of gebang starch (putak) with urea in concentrate feed as feed supplements on the growth of Bali cattle. Sixteen male Bali cows (body weight of 192.71±19.17 kg) used in a completely randomized design 4 x 4. Livestock were randomly allocated to get one of the treatments of the use of purea (cooking of putak meal with 6% urea) in concentrate feed, namely T0: putak meal mixed with urea (the amount of putak meal 60% in concentrate, the amount of urea 3% from putak meal), T1: purea 20%, T2: purea 40%, T3: purea 60%. King grass is used as basal feed in comparison with a 60: 40 concentrate. The research results showed the consumption of dry matter, organic matter, crude protein, crude fiber and total digestible nutrients did not differ due to the use of purea, but the digestibility of dry matter, organic matter, crude protein and crude fiber, weight gain, and efficiency of feed use differ among the treatments. The use of purea to 40% level in concentrate feed is better in increasing the growth compared to the use of urea mixture with putak meal without cooking. The use of purea does not cause cattle to experience health problems or poisoning.
