Abstract

One of the alternatives to solve the problem of less fossil energy is to utilize plant as a new source of energy, i.e Jatropha curcas, known as physic nut. This plant has been promoted as a source of energy as its seed contains high level of oil which can be used as biodiesel. The meal produced after pressing the seed will become a by product which contains high level of protein but also contains several anti nutritive factors or toxic compounds. This causes a problem to utilize this seed meal for animal feed. This paper descibes the nutritional quality and anti nutritive factors of jatropha seed meal, detoxification of jatropha seed meal and its utilization as feed ingredient and the problem of its utilization. Jatropha seed meal as a feed ingredient has to go through a combination process of detoxification. There is a need to find a cheap and easy detoxification technology to produce a safe and high nutritional quality of jatropha seed meal for animal.   Key words: Jatropha curcas, anti nutritive factors, detoxification, utilization, problem

Abstract

Tannin can be found in many tropical plants and the presence of tannin may reduce the nutritional value of feed. However, it can give beneficial effect as it protects the protein from its excessive degradation in the rumen. Tofu waste is abundant in a country, including Indonesia, where tofu is produced widely. A feeding trial on sheep to study the effect of tannin on microbial protein synthesis and condition of rumen fermentation, digestibility and N retention of feed containing tofu waste was conducted. Fifteen sheep were allocated to one of 3 treatments, i.e: 1) control treatment, feed without tannin, 2) feed + tannin treatment and 3) feed + tannin + polyethylene glycol (PEG) treatment. The sheep was placed in the individual metabolism cage. They were fed with treatment feed for 14 days and then, the following 7 days, faeces and urine were collected. At the end of the treatment, rumen fluid was taken from each sheep before and after feeding. Rumen parameter (pH, ammonia, SCFA, protozoa) and microbial protein synthesis, digestibility, nitrogen retention were observed. Results showed that inclusion of 4% tannin in the feed depressed ammonia production in the rumen of sheep before and 3 hours after morning feeding. Total SCFA and individual SCFA were not different among treatments. Tannin did not affect daily feed intake. Tannin lowered the dry matter, organic matter and protein digestibilities but it significantly reduced ADF digestibility (P < 0.05) and tended to reduce NDF digestibility (P < 0.1). However, tannin increased the microbial protein synthesis. PEG addition was expected to bind tannin and alleviate the negative effect of tannin. Key Words: Tannin, Acacia Mangium, Polyethylene Glycol, Tofu waste, Digestibility
