Palm oil petiole (POP) is a pruning by-product from palm oil plantations. POP is the stalk of the palm oil frond (POF) without the leaflets and the outer layer. By weight, it contributed about 30 percent of POF. POP was a possible alternative for POF in feeding Bali cows (Bos sondaecus) since Bali cows we observed to reject fresh POF. Central Bureau of Indonesian Statistics (2006) reported that the production of POF was around 10,869,365 t from around 3,682,900 ha of palm oil plantation in Indonesia which is equivalent to 3,260,810 t of POP. POF are successfully used as feed for Bos taurus and Bos indicus and there are a lot of studies being done, especially in Malaysia. Alimon and Hair Bejo (1995) reported that the chemical composition of POF is 47, 385, 787, 556 g kg-1 and 5.65 MJ kg-1 for crude protein (CP), crude fibre, neutral detergent fibre (NDF), acid detergent fibre (ADF) and metabolisable energy respectively. However, there is no information on the nutritive value of POP and its palatability in Bali cows. The aims of this study were to evaluate the nutritive value of POP, and palatability of POP types by Bali cows when processed in several forms. read more (word) Proceeding British Sociecty of Animal Science 2009 p 093 (pdf).

ABSTRACT pdf. A study was done to examine the effects of concentrate level and the length offattening on the daily weight gain (DWG), feed intake and feed conversion efficiency of Pesisir Cows. Twelve cows between 2 and 2.5 years old with live weights of 126 to 170 kg were used. The study used a randomized block design in factorial arrangement with two factors. The first factor was concentrate level (CL) with either 50 % concentrate and 50 % of ammoniated rice straw or 75 % concentrate and 25 % ammoniated rice straw (defined as Al and A2, respectively). The second factor was the duration of fattening, either 3 or 4 months (Bl and B2, respectively). There were significant effects of CL on DWG (PO.05), no significant (P>0.05) effect of LF on DWG and no CL x LF interaction on DWG. There were no significant (P>0.05) effects of CL on DMI but LF significantly affected (P<0.05) on DMI. There were no interaction effects of CL and LF on DMI. CL significantly (PO.05) decreased FCR while LF did not significantly affect FCR. There were no significant effects of interaction between CL and LF on FCR

Asystasiu gangetica (AG) and Passiflora foetica L (PF) are kind of wild plants that usually grow in area such as rubber, palm oil plantation, or in any other area like a long the side of padi field, a long the road. Reid (1990) mentioned that mostly there are 10,000 species of wild grass. These. might be part of those species. Physiologically these plants can be classified as roughage. Therefore, these might be potentially, used as feed ruminant feed, in Jambi. Indonesia. Few farmers have fed these plants to goat, cow and buffalo as animal feed but it was not optimal. The objective of this study was to examine the nutrient content of AG and PF and the palatability 01, these plants fed to the kacang goat (local coat) (KG).

Indonesia is the world’s third largest producers of coffee with the residual coffee pulp being included in ruminant diets. However, coffee pulp has a low palatability although studies have shown that this can be increased by ensiling. In addition, coffee pulp contains anti-nutritive factors such as caffeine and tannins. Washing the residue with hot water reduces caffein concentration by about 90 % (Kiflewahid, 1982). In this study, the effects of washing and ensilage on the degradability profiles were examined by estimating gas release using the Reading Pressure Technique.

Introduction Considerable efforts have been made regarding the use of faecal material to provide a microbial inoculum for in vitro feed evaluation systems. However total gas production, rate of gas release and the extent of degradation of feeds incubated using faecal inoculum are lower than those incubated in a rumen fluid medium. It has been suggested that this is due to lower microbial activity, a consequence of the different microflora and reduced microbial numbers (e.g. Mauricio, 1999). Microbial populations are dynamic so, as their enzyme activity profiles change rapidly, little information is obtained from examining these. However, their hydrolytic activity as reflected by their ability to degrade specific substrates can be simply measured and provides a potential method with which to assess the quality of inocula with respect to their use in in vitro systems. The data presented here are from a larger study in which the differences between the hydrolytic activity of faecal material and rumen contents as influenced by the time of sampling were assessed in vitro .

Introduction The use of faecal inoculum in in vitro feed evaluation methods was examined by Balfe (1985). However, there is limited information concerning the chemical composition of faeces and factors affecting this. The chemical composition of faeces may reflect the microbial population and hence its fermentative activity. A knowledge of the faecal composition is essential as this affects the quality of faecal inoculum. The objective of this work was therefore to study the relationships between diet and the chemical composition of faeces using data obtained from sheep.
