Abstract

The problems of ruminant feeding have received considerable attention in the tropics.  In the tropics, most ruminants are fed on low-quality roughages, agricultural crop-residues and industrial byproducts. Urea is widely available and has been used as a source of ammoniation to improve the feeding value of various grasses and crop residues. Furthermore, urea treatment as a supplement is relatively easy to apply, handling, inexpensive and valuable substitute for natural proteins in the ration. Although the use of urea has potential economic advantages for N sources, there are limitations and disadvantages to its use. Excess level of urea feeding may develop a problem of urea toxicity, due to poor mixing of feed or to errors in calculating the amount of urea to add to the ration. This paper aims to summarize some of the results of research on the benefits and possible negative effects of urea use as supplement to ruminants feed.

Abstract

The basic reason for poor performance of livestock in developing countries, include Indonesia,  is qualitative fluctuations in feed. Therefore knowledge in utilizing agroindustry byproduct as feedstuff to meet nutrient requirement of animals is important. Rice straw is a crop residue of rice production and can be used as a feed for ruminants because it is easily and cheaply available in many Asian countries. Rice straws have low nutritive value and it is generally limited by several factors such as the low nutritional quality due to high fiber content and lignification process. In Indonesia, rice straw has been widely utilised in livestock feeding systems, thus the need to improve them is imperative as they are an abundant crop residue. Much more attention has been paid to improving its feeding value in order to increase livestock productivity. Many processing methods to improve the nutritive value of rice straw have been investigated. These methods can be classified as physical, chemical or biological. Usually, processing methods improves the nutritive value of straw by increasing its digestible energy content, by increasing feed intake, or by a combination of the two. This paper aims to examine the potential of rice straw as basal feed livestock as well as efforts to improve their nutritional value.Key words: livestock, rice straw, processing methods, nutritional value
