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

ABSTRACTMolasses is a by-product or end product of sugar cane (Saccharum officcinarum L.) or sugar-beet (Beta vulgaris L. var. Conditiva) resulting from the manufacture of raw or refined sugar and consisting of structural sugars, hemicelluloses and minerals. It is mainly used to improve appetite of animals or add extra energy when prices of molasses are lower than that of other energy sources. Molasses can be a key ingredient for cost effective management of feeds and pastures. Supplementing poor quality feeds with molasses will increase feed intake and improve palatability. However, molasses can be toxic if fed at ad libitum or free choice, therefore, it is recommended that molasses should be supplemented in a restrictive form. These molasses poisoning papers and the negative impacts arose from long-standing studies because the poisoning is now rare. However, although this time is rare but did not close the possibility will appear again, Especially if given in an uncontrolled amount. Thus, this paper aims to remind users of molasses in the livestock industry to be wiser in their use. Key words: Key words: molasses, sugar cane, palatability, toxic

Abstract

Mastitis means inflammation of the udder and is a common disease among dairy cows worldwide. It is subdivided into clinical mastitis and subclinical mastitis, both influence milk quality and quantity, and mastitis is therefore of major economic concern for the farmer. The incidence rate of mastitis varies between herds and depends on the exposure to pathogens, environmental and management factors and the immune status of the cow. Mastitis is associated with release of free radicals, increased total oxidant capacity and decreased total antioxidants capacity in milk. Vitamin C, E, , α tocopherol, A, β-karoten and trace mineral (Cu, Zn, and Se) feeding, as an antioxidant, in dairy cows have shown appreciable protective effects by reducing the incidence of mastitis.The purpose of this review is to discuss the role of Vitamins C, E, α tocopherol, A, β-carotene, Cu, Zn, and Se in the incidence of mastitis.

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

Abstract

Bloat is a form of indigestion characterized by excessive gas accumulation in the rumen. Bloat occurs when the eructation mechanism is disturbed and the rate of gas production exceeds the animal's ability to expelled it. Bloat can occur very quickly due to excessive volume of gas produced in the rumen. Bloat can be classified into a primary bloat (frothy / wet bloat) mixed with rumen and secondary bloat / free bloat (free gas / dry bloat) contents in a separate free gas. There is no single method of preventing bloat events that can be applied in every different situation, however, there are methods of management in prevention and treatment that can help minimize risks. In Indonesia, although the incidence of bloat is quite high, but no data is well documented. This paper aims to review the bloat and problems in terms of understanding the clinical symptoms and the results of laboratory examination, prevention and treatment so that it is expected to be implemented by peers and field officers to reduce the risk of loss of farmers due to possible livestock death.
