Utilization of Inconventional Feedstuffs for Animal Production
Full text linkIn the recent past, the increasing cost of imported feed ingredients, known as the main components of completed ration, caused the bankrupt of the intensive poultry industry. On the other hand, negative affect was faced by ruminant animal due to the potential land used for agriculture has been swidden/shifted to non-agricultural function, resulting in a shortage of feed sources, availability and supply for ruminant animal. Consequently, the animal productivity is low. There is ,therefore a need to look for cheaper alternative sources of feedstuffs has to be given in order to optimize the productivity of animal utilizing available feed in this country. A number of investigations have been done in order to overcome the feed availability problem, including the potential of crop by-product as a part of concentrate component. Although, crop by-product is always generally related to cheaper feedstuff, there are several matters need to be considered. Those factors are the continuation of crop by-product availability, the nutrient content of crop by-products, the possibility of any limiting factors, such as the existence of toxic constituents as well as the processing needed before feeding to the animal. Experiment results on utilization of several crop by- products, such as rice bran, cassava leaves, coconut meal, palm oil cake, cocoa pod husks, tofu residue, shrimp (Penaeus Sp) meal, banana steam and rami (Haramaj Sp) leaves in feeding ruminant animal (cattle and sheep) and non-rumiants animal (local and imported poultry as well as duck) will be reviewed in this paper. Key words: Inconventional feedstuffs, crop by-product, animal productio
Spreading Of Avian Flu On Duck And Its Impact On Social Economy: Lesson Learnt From Avian Flu Cases On Chicken
Full text linkBird flu disease that attacks duck dismissed the notion of duck immune to bird flu disease. Learning from the experience ofbird flu disease that attacks poultry in the year of 2004-2005, necessary to measure the spread of disease prevention bird flu in ducks. This paper aims to describe the business and trade patterns of duck associated with the spread of avian influenza and predict the socio-economic impact of bird flu on duck farms in Indonesia. Duck rearing patterns mostly are in the extensive and semi-intensive system, that have large potential disease transmission occured between duck and wild. Illegal trade in the crossborder region and imports from countries that re-export it, ias alo become potential as well as the entry point to the bird flu virus in Indonesia. Ducks trade between regions by land transportation is difficult to control as well becomes the potential media to spread of the virus to a wider area. The economic impact of bird flu on duck business occured due to the death of ducks, decline in production and loss of job opportunities, while that on demand reduction was not significant. Small scale farmers that were bankrupt as a result of bird flu outbreaks may require technical assistance and access to capital for recovery. In the future, development of ducks business should be directed at duck farms into a semi-intensive and intensive system to facilitate the control of epidemic diseases.Key words: Bird flu, ducks, impact, social economi
Methods of Detection Anthelmintic Resistance in Sheep and Goats
Full text linkAnthelmintic resistance to gastrointestinal nematode of sheep and goats has been reported world wide to all of broad spectrum anthelmintic types currently available, such as benzimidazoles, levamizole and ivermectin. In South-East Asia anthelmintic resistance to small ruminants was reported in Malaysia, Thailand and Philippines. In Indonesia resistances to albendazole have been reported from sheep farm in Bogor. With regard to resistance cases, early detection for anthelmintic resistance on sheeps and goats to spesific types of anthelmintic that commonlly used are required to plan rationale strategic control program. Detection methods for anthelmintic resistance are Fecal Egg Count Reduction Test (FECRT), Egg Hatch Assay (EHA) and Larval Development Assay (LDA). LDA is an in vitro assay to detect anthelmintic resistant in the major of gastrointestinal nematodes on sheep and goats that have just been introduced in Indonesia. This paper explains the comparison of three detection methods and goodness of LDA compared with other two methods. Key words: Anthelmintic resistance, sheep, goat, Fecal Egg Count Reduction Test (FECRT), Egg Hatch Assay (EHA), LarvalDevelopment Assay (LDA
Epidemiology, Diagnosis and Control of Infectious Laryngotracheitis in Chickens
Full text linkInfectious laryngotracheitis (ILT) is an acute, highly contagious respiratory disease of poultry characterized by respiratory disorder such as coughing with blood exudate from the trachea. The disease is caused by Herpesvirus of the family Herpesviridae and subfamily of Alphaherpesvirinae. The virus has been characterized as Gallid herpesvirus-1. ILT is worldwide distribution and has been reported to be present in Indonesia. However, the information on the disease in this country is limited. Spread of the ILT among chickens can be by inhalation or digestion, but ELT virus is not transmitted vertically by eggs . The morbidity rate of the disease is about 90-100% with mortality rate between 10-70%. ILT may reduce body weight gain and reduce egg production, so it causes lost in layers, broilers as well as breeders . Diagnosis of the disease can be based on the isolation and identification of the virus using embryonated chicken eggs. There is no treatment available for ILT, so the control of the disease is mainly by vaccination. To ensure the results of vaccination program, monitoring antibody titres following vaccination is essentially required. The most widely used serological test for antibody monitoring is enzyme-linked immunosorbent assay (ELISA). Keywords : ILT, epidemiology, diagnosis, control, chicke
Productivity and Utilization of Leguminous Tree Indigofera zollingeriana on Dry Land
Full text linkIndigofera is well known as tarum plant, has about 700 species, including Indigofera zollingeriana. These plants are leguminous species that have high nutrient content and production as well as tolerant to abiotic stresses. This plant originated in tropical Africa, Asia, Australia, and North and South America, then spread to arid zone of Africa and Asia. In early 1900, it was brought by Europeans colonial to Indonesia. Indigofera can grow well at altitudes between 0-2200 m above sea level, with rainfall between 600-3000 mm/year. It can be used as a fodder crop because it has high nutrient content and production. It can be harvested at the age of eight months with an average production of 2,595 kg of fresh biomass/tree, with a total production of fresh approximately 52 tons/ha. Indigofera zollingeriana has crude protein content of 27.60%; neutral detergent fiber (NDF) 43.56%; acid detergent fiber (ADF) 35.24%; calcium (Ca) 1.16%; phosphorous (P) 0.26%; in vitro-dry matter digestibility (IVDMD) 67.50%; organic matter digestibility (IVOMD) 60.32%; 0.08% tannins and 0.41% saponin. Additionally I. zollingeriana is often used as green manure, cover crop in plantation areas, fabric dyeing and therapeutic herbs. Key words: Indigofera zollingeriana, characteristics, usage, dry lan
Prospects on Cattle Based Crop-Livestock Systems for The Irrigated Paddy Field in Lombok
Full text linkGrouped livestock management is one of the characteristic animals raising in Lombok. In the year of 2000, there were 1096 farmers' group that had a very potential opportunity to optimize the livestock productions through the crop-livestock systems approach. The assessment of this approach for the irrigated paddy field area has being conducted in the village of Sepakok, sub- district of Pringgarata, district of Lombok Tengah. The objective of the study was to improve the efficiency and sustainability of the crop-livestock system as well as environmentally friendly issues. A total of 112 household farmers were involved in the study, joined in the "Gerak Maju" group farmer with 334 head of cattles and 35 ha paddy filed. Improving farming systems efficiency has been implemented through the technology introduction of rice straw fermentation as cattle feeds, the use of Progesterone Intravaginal Sponges (PIS) for estrous synchronization and compost processing as well as its uses for crips. The results has shown that fermented rice straw could be used as basal feed, given ad-libitum and 5% of native grass from the body weight yield an average daily gain of 290 gr. The use of fermented rice straw has decreased the straw-field in the field after harvesting period, so that it could be storage and used them for the dry season. The use of manure compost could reduce the production cost for anorganic fertilizer and weed. It significantly affected to the vegetative growth of some horticultures. Part of the compost production has been marketed in some areas to give additional income of the farmers. The crop-livestock system approach with cattle based in the irrigated paddy field was recognized as one of the potential systems that could be impemented in Lombok as well as other region with the same agro-ecological zone.

Crop Livestock System in South Sulawesi: Review of Implementary Activities
Full text linkSouth Sulawesi has considerated having amount of rice field i.e. 598,218 hectare about 21.49% out of the total land for agriculture activities. Some of these are irrigated rice field, either technical or non-technical irrigated which contributes to the production of rice. These land is also used as production center for cattle. The population of cattle is 805,868 heads in 1995 decreased to 749,327 heads in 1999 (1.8% decreased each year). Both commodities (rice and cattle) were agribusiness oriented. However, the productivity of rice has been facing leveling off, with the maximum average is 4 – 6 ton/ha. It is likely that the due to phenomena degradation of the soil, so that it can not support the optimum condition of the growing rice because of inadequate a certain nutrient or lack of organic carbon which can not support the uptake of a certain nutrient. One of the alternative to improve these condition was the application of compost which produced from cattle manure. The main feed of cattle can be provided from rice straw, which is available with the amount of 4-5 ton/ha/growing season. It means that the potential production of rice straw every season was 1,196,432 heaps, which can be used as cattle, feed to increase cattle production. Each cattle could produce 4 – 5 ton fresh manure/year, which can be processed to cattle manure (compost) at the rate of 2 ton/year/cattle, so that it is estimated the number of compost can be produced in South Sulawesi was 1,498,654 ton/year. This can be applied to 749,327 ha of rice field with the rate of 1.5 – 2 t/ha. Therefore, the integration of cattle into a rice system could increased productivity of the two commodities. The implementation of CLS in South Sulawesi has the following problems: a) in the intensive area of growing rice, the threshing mashed was done using power thresher, and cutting the rice straw at the top (one third from the top) which cause problem for farmers to collect the rice straw for cattle feed, b) most of farmers have no any experience in using rice straw for fodder, c) the majority of farmers do not have animal shelter.

Crop Livestock Integration in South Sumatera Tidal Swamp Land: Potency, Constraint and Solution Alternative
Full text linkDecreasing areas of fertile soil in Java due to non agriculture purposes and increasing demand for agriculture products along with increasing human population and industrial growth have led to cultivate marginals soils like tidal swamp land areas to the development of agriculture. Integrated farming system concepts involving food crops such as rice and corn with cattle or buffaloes could be applied in tidal swamp land areas of South Sumatera. They were supported by appropriate carrying capacity and planting pattern, and sufficient supply of rice and corn straws as feed. However, infrastructural constraints, such as isolated location, and inappropriate facilities, especially by transportation were found. An integration of crop and livestock that is supported by transportation through rivers connect to markets is recommended. If such effort is sucsessful, it will increase crop production and ruminant productivity, significantly. Key words: Tidal swamp land, carrying capacity, planting pattern, agricultural by productc
Viral Arthtritis in Chicken: Problems and its Control
Full text linkViral arthritis in chicken is caused by avian reovirus infection. The infection readily occurs via the egg when the breeder hens go through a viraemia resulting in the virus being transmitted to the progeny. Horizontal transmission occurs through the direct contact. This disease causes leg weakness, swelling the hock joint, lameness, gastrocnemius tendon rupture and femoral head necrosis. Affected birds are reluctant to move, unable to seek food or water and rapidly become dehydrated and die. Economic losses may be due to mortality or culling, reduce growth or egg production on to down to carcass downgrading. Demonstration of Reovirus in the tendon sheath by fluorescent antibody technique (FAT) or isolation in chicken embryo liver (CELi). Group of specific antigens are demonstrable by the agar gel precipitin test (AGPT). Reovirus grows readily in the embryonating chicken egg following inoculation via the yolk sac, chorio allantoic membrane (CAM) or allantoic cavity. Vaccination to induce maternal antibody can be done with inactivated or active vaccines or combinations of both. For prevention of vertical transmission, egg for hatching should be come only from flock known to be free from reovirus infection. Key words : Viral arthritis, lameness, vaccinatio
Solid Substrate Fermentation of Cassava Peel for Poultry Feed Ingredient
Full text linkCassava peel which is not used during cassava starch extraction is one of potential resources for animal feed. However, cassava peel has low level protein content, high level crude fiber, and high level of toxic cyanogenic compound. These problems limit the utilization of cassava peel as feed. Solid substrate fermentation using mold may be a solution process to increase its nutritional value and decrease toxic level of cassava peel. In this paper, matters that related with cassava peel fermentation process are subsequently described, namely: (i) problems of cassava peel; (ii) biodegradation and detoxification process; (iii) solid state fermentation methods on cassava peel; (iv) nutritional quality of fermented cassava peel; and (v) application of fermented cassava peel in poultry feed. The fermented cassava peel application is compared with those of cassava root and waste (onggok). Addition of nitrogen inorganic in the fermentation process increases the mold growth and protein content of the product, while fiber and cyanogenic contents are decreased due to mold degradation activity. The fermentation process may be carried out using only the cassava peel as the substrate or mixed with wheat flour, using indigenous microbes, Aspergillus niger or a white rot fungus, Panus tigrinus as inoculum. As well as fermented cassava root and waste, fermented cassava peel can be used to substitute maize as poultry feed, although it is reported that the optimum substitution in broiler ration is only 10%.
