Abstract:Feeding high concentrate diet, characterized with high starch and low fiber is applied to increase energy intake for an optimal production performance in ruminants. However, the prevalence of digestive disorder namely ruminal acidosis has been reported as drawback of this feeding strategy. This encourages farmers and nutritionist to supply adequate fiber in the diet to meet minimum dietary fiber requirement. However, feeding high forage diet is reported to give adverse effect on production performance, thus economic loss for farmers. Therefore, some sorts of artificial fiber utilizations have been introduced to reduce the risk of nutritional diseases as well as improving ruminant productivity. The utilization of rumen mechanical stimulator aims to maintain a healthy rumen function in ruminants fed with high concentrate diet. Objective of this article is to review recent development of rumen mechanical stimulators utilization, a pseudo fiber to substitute forage physical function in the rumen of ruminants. This review highlights the use of rumen mechanical stimulators in dairy cattle, beef cattle and sheep with particular attention in rumination time and rumen parameters. In conclusion, rumen mechanical stimulator is attributable to minimize metabolic problem associated with high concentrate feeding by providing mechanical stimulation on the rumen wall.

Abstract:Prevention of mastitis is essential, as one of the efforts to control disease in dairy cow. Dry period has implications to understand the mastitis and its control strategies. The udder is very susceptible to be infected both at the beginning and towards the end of dry period. This is linked to physiological changes in udder. Treatment with antibiotics during the dry period can reduce new infection about 82% and has several advantages. The success rate of subclinical mastitis treatment is much higher (80-90%) compared to the treatment during lactation (30-40%); the doses of antibiotic can be higher and safer, due to its retention time in udder becomes longer; the risk of antibiotic contamination in milk can be avoided because the udder is not milked. Antibiotic application during dry period is the best way to treat subclinical and chronic mastitis. Treatment during dry period is a specific mastitis control for intramammary infection to avoid economic losses. Key words: Antibiotic, dry period, subclinical mastitis

Abstract:Highly Pathogenic Avian Influenza (HPAI) H5N1 is endemic in Indonesia especially in unvaccinated sector-4 poultry. Considering that vaccination against influenza viruses does not induce sterilizing immunity and the source of infection is prevalent around the vaccinated farms, infection in the commercial layers and breeders may be common. Because infection in vaccinated birds is usually subclinical, its presence is unnoticable. The virus in such farms may be circulated persistently and become the source of infection to the surrounding areas. The test, Differentiation Infected from Vaccinated Animals (DIVA) that can be used to identify subclinically infected farms is not available yet in Indonesia. Observation on sentinel chicken among vaccinated birds is a sensitive and accurate method but unsafe for HPAI. The DIVA method based on heterologous neuraminidase has been successfully used in Italy, but it is difficult to be applied in Indonesia. The DIVA method based on Ectodomain protein M2 virus Influenza (M2e) uses antibody against M2e as infection marker and does not limit the subtype of vaccine used. This method is potential to be used in Indonesia because the M2e is very conserved across all avian influenza viruses and has high proportion of post-infected seroconverted birds. Key words: H5N1, DIVA test, heterologous neuraminidase, M2e, vaccination

Abstract:Establishment of dairy cattle development region needs to be conducted in accordance with the national dairy industry development plan. Dairy cattle regions have been designed and equipped with infrastructure supplies, supporting facilities, technologies, finance, processing, marketing, institutional and human resources. Dairy cooperative is one of the marketing channels of milk and milk products which have strategic roles to support the national dairy industry. Collaborations between dairy cooperatives and smallholder farmers within a district region have to be done based on agricultural ecosystems, agribusiness system, integrated farming and participatory approach. This may improve dairy cooperatives as an independent and competitive institution. Strengthening dairy cooperatives in national region dairy cattle was carried out through institutional inventory and dairy cooperatives performance; requirement of capital access, market and networks as well as education and managerial training; certification and accreditation feasibility analysis and information and technology utilization. Establishment of emerging dairy cooperatives towards small and micro enterprises is carried out by directing them to establish cooperatives which have legal certainty and business development opportunities. The impact of strengthening dairy cooperative may support dairy cattle development through increase population and milk production. Sustainable dairy cattle development needs to be supported by regional and national government policies. Key words: Dairy cooperatives, animal husbandry district development, dairy

Abstract:The government paid great attention to develop small-scale poultry business, to reduce poverty alleviation and increase employment opportunities. The government has established various policies to encourage the growth of poultry production cluster (PPC) in rural areas. However, the fact shows that these policies have not been able to solve the problems. Small-scale poultry business is particularly vulnerable to economic changes, including animal diseases. The economic crisis of 1997-1998 and avian influenza outbreaks in 2004-2006 had caused most of small-scale enterprises collapsed. Government policies to develop small scale poultry business which is environmental friendly are required so its existence does not disturb the public. Since 2006, the government has established various policies, ie. Village Poultry Farming (VPF) and compartment structuring. Based on evaluation and existing cases, the results have no meet the expectation yet, due to lack of sustain supervision. On the other hand, small scale poultry business has been set up on PPC’s under partnerships with companies. The government is expected to continue VPF program and should pay attention to the development of PPC that basically has been accepted by rural communities. Key words: Government policies, poultry, small scale, environmental health

Abstract:Canine parvovirus (CPV) is a highly infectious virus. The virus causes death in dogs worldwide. The mortality rate due to infection of CPV in dog reaches 91%. Prevention of CPV infection in puppies has been done by vaccination which is effectively proven. Protective mechanisms of maternal antibodies contribute to the failure of vaccination. Highly stable characteristics of parvovirus enable the virus still exist in the environment. Various therapies are performed only to suppress the clinical symptoms but can not reduce puppy mortalities. This review discusses CPV alternative therapy and the advantages using immunoglobulin Y (IgY) specific antibodies isolated from chicken egg yolk. Immunoglobulin Y will neutralize the virus, so it can not infect host cells. Intravenous IgY therapy has shown to suppress the spread of CPV infection and prevent death. Key words: Parvovirus, canine, immunotherapy, immunoglobulin Y

Abstract:Abdominal fat in broiler carcass is considered as a waste and its existence reduces the carcass quality. Abdominal fat deposition is affected by several factors such as genetic, nutrition, feed, sex, age and environment. Reducing abdominal fat deposition can be carried out by regulating the nutrient intake to ensure that no excessive nutrient was consumed. Nutrition effects to reduce abdominal fat deposition are associated with nutrient concentration of ration and quantity of daily feed intake. Daily nutrient intake can be limited, especially through restricted feeding. It is concluded that an appropriate feeding management can reduce abdominal fat deposition in broiler. Key words: Broiler, abdominal fat, feed
