Performance of Kacang Goat Fattening Intensive Using Complit Feed with Different Levels of Liquid Smoke

Kacang Goat is goat local native to Indonesia and scattered throughout provinces in Indonesian [35], the population the most between type others [9] [30]. Kacang Goat has value carcass percentage ranges from 43-44% [33] [ 18/19]. Indonesian has two season that is season dry between In April-October and season rainy day between month October April. So that quantity and quality feed fluctuate [32] For that needed feed Complete formulation that capable hit he needs nutrition /feed livestock. Utilization of waste agriculture combined with industrial waste and the rough tree is wrong one solution provision feed in a manner continuous. Liquid smoke is one of the materials that can be used as animal feed because it has components including phenol, acids, and carbonyl. These substances for the prevention of free radicals, so that the feed nutrients are not degradation. According to [13] polyphenols and tannins are able to bind proteins to avoid degradation of microbial enzymes and protease enzymes in the rumen. Tannin is also able to precipitate proteins with functional bonds to produce complex crosslinking into tannin proteins [6] Liquid smoke containing VFA, it is precursor source energy for bacteria and the host. The presence framework carbon for rumen microbes so able to forming microbial proteins more many for ruminants. The components possessed by liquid smoke are expected to be able to improve carcass, commercial cut carcass and carcass composition of Kacang goat. The use of liquid smoke up to 1% of the feed can improve the quality of meat, the amount of albumin in the blood of broiler chickens [38] and increase the performance of mice up to a dose of 15 g / kg of feed [5] Concentration of liquid smoke in UMB unpacking feed supplement Bali cattle capable for increases brightness meat of muscle Longissimus dorsi[2]. The purpose of this study is to analyze the percentage of carcass, carcass composition and commercial carcasses percentage of Kacang goats through intensive fattening using complete feed added with liquid smoke.
