Strategy to Fulfill the Requirements for Concession and Release of New Animal Breed or Strain
Full text linkLaw of the Republic of Indonesia Number 5 of 1994 on Ratification of the United Nations Convention on Biological Diversity and Regulation of the Minister of Agriculture of the Republic of Indonesia Number: 117/Permentan/SR.120/10/2014 regarding the concession and release of animal breed or strain in Indonesia should be followed up. This paper aims to improve the understanding of concession and release of animal breed or strain. Requirements of breed or strain concession has to declare (a) Its origin; (b) Original geographic distribution where the breed or strain formed; (c) Characteristics; (d) Genetic information; (e) The animal number and structure of their population; and (f) Animal picture. Requirements for the release of breed or strain should have (1) The method to obtain animal breed or strain; (2) Characteristics; (3) Genetic information; (4) New invention, unique, uniform and stable (NUUS); (5) The current number of animal; (6) Animal picture; (7) A guarantee certificate of quality standard; and (8) At the time of receipt of the request release, breed or strain has never been traded/distributed in Indonesia or already traded less than five years. Therefore, the government operational policy is necessary to regulate the preservation and improvement of animal genetic resources either breed or strain beneficial for future generations
Vector Control of Zoonotic Arbovirus Disease in Indonesia
Full text linkZoonotic Arbovirus diseases which are caused by the genus of Flavivirus, Alphavirus, and Bunyavirus, are transmitted through potential vectors. These diseases are commonly occurred, especially in tropical countries, including Indonesia. They can affect the economic development because of the high morbidity and mortality. This paper describes the incidence of zoonotic Arbovirus in Indonesia and the strategy to control its vector. Factors that support the occurrence of zoonotic Arbovirus diseases are environmental, demographic and behavioral changes, as well as advanced technology, transportation and global trade. These diseases would not occur without the role of vectors. Vector control can be carried out effectively through longitudinal surveillance to identify types of potential vectors in the area. Therefore to prevent the increased incidence of the diseases, controlling the vector is necessary
Utilization of Assisted Hatching Techniques to Enhance Embryo Implantation
Full text linkGestation is the main goal for in vitro fertilization. The embryo that has been developed outside the body will be transferred directly into uterus leading to the process of hatching, implantation, and pregnancy. However, approximately 85% of embryos that have been transferred were failed to implant and it might be caused by hatching failure. Hatching is the process of releasing embryo from zona pellucida. If this process does not occur, it will cause pregnancy failure. Assisted hatching is a mechanism that dealing with thinning, slicing or artificially making holes in the zona pellucida to improve hatching. The process can be applied both in fresh or frozen embryos. This review describes various methods in assisted hatching such as enzymatic, chemical, mechanical, and laser beam as well as their advantages and disadvantages. Generally, some researches show that the technology of assisted hatching can improve the percentage of hatching and implantation of the embryo. However, in spite of the benefits, there are such weaknesses find in the zona pellucida of the embryo that has been manipulated such as toxic hazard medium, the risk of damage to the blastomeres or monozygotic twinning. Therefore, it is advisable to perform assisted hatching in certain cases that tends to face obstacles during the process of hatching such factors as age, embryo quality, the thickness of the zona pellucida and the number of failures in the in vitro fertilization program
Indonesian Dairy Industry Perspective Within the ASEAN Economic Community
Full text linkMany of Indonesian main manufacturing industries based on agriculture should be more responsive to the challenging domestic and global strategic environment, including the newly emerging ASEAN economic community (AEC) which will be effectively implemented by the end of 2015. Dairy industry in Indonesia is a very potential business to play significant role in the ASEAN market based on the existing dairy population, feed resources and the number of dairy farmers. Recently, small and medium enterprise (SME) model in Java has been developed for processing milk. They provide higher farm gate prices under partnership agreement which created a good benchmark and business model for the future dairy industry to adopt. This new attractive business environment gives higher return to the farmers as opposed to the tradition of paying low farm gate milk prices. As feed represents 80% of the total production cost, special attention must be given to land availability to increase feed supply in terms of quality and quantity. Consequently, sustainable support from both central and local government is very critical to keep the partnership model between farmers and the SME milk processing. It also opens new opportunity to increase the linkage more closely between producers and milk processing plants.
Characteristics and Applications of Nanoparticles in Manipulation of Livestock Reproductive Hormones
Full text linkThe research on hormone packaged in very small size particles began to develop in recent years. Nanoparticles are defined as particulate dispersions or solid particles with a polymer used as a component of potential hormone carrier as effective drug because of their ability to circulate and to release in a controlled period in the body. This review describes a variety of methods, characteristics and applications of nanoparticles hormones usages for animals. In general, several studies indicated that the formation of the hormone nanoparticles using polymer accompanied by distributing a good and stable of molecular mass, can be used as a carrier component of hormones as well as considering the negative effect
Efforts to Develop Rapid Technology of In Vitro Transcription and Translation in Vaccine Synthesis in Indonesia
Full text linkProduction of functional protein (including vaccine) using conventional technology in embryonated chicken eggs is laborious and lengthy. The use of chemical synthesis is not practical for peptides longer than 20 residues. In contrast, in vitro transcription and translation technology can directly utilize polymerase chain reaction (PCR) product as template for vaccine synthesis within two hours accurately. Moreover, up to 1-10 mg/ml protein can be produced using the technology compared to conventional method that only gives approximately one dose per egg. In this review, advantages and disadvantages of animal vaccine generation using conventional and in vitro methods would be described. In vitro transcription and translation technology can be considered as the most practical and efficient technique for rapid screening and generating new animal vaccines
The Use of Plant Essential Oils as Feed Additives for Ruminants
Full text linkPublic awareness of health risk and environmental problem caused by unappropriate use of antibiotics and hormones resulted in prohibition of antibiotics in feed since 2003 in European Union. The regulation stated that ruminant feed additives should not have an adverse effect on animal health, human health and environment. Plant essential oils are recommended for animal feed additive because of their antimicrobial effects. The major bioactive compounds of essential oils as rumen manipulator have not been yet evaluated on in vitro and in vivo studies. Some plants essential oils showed their function to increase dry matter digestibility, rumen VFA products, N-NH3 and reduce rumen methane production in the in vitro study. The studies still have not enough yet to prove the use of essential oils as ruminant feed additive to increase nutrient digestibility and mitigate rumen methane production. Combination of some plant essential oils or some of their main active components may be more advantageous because of their sinergistic effects
Hantavirus Infection: Anticipation of Zoonotic Disease in Indonesia
Full text linkRecently, the evidence of Hantavirus infection in human and animals is increasing, and new Hantavirus strain has been identified. The disease causes clinical renal and lung disorders and fatal to human. The presence of new Hantavirus strain, lack of available quick and accurate diagnostic tool, asymptomatic clinical signs and paucity of disease information, will inhibit disease control especially in the developing countries. The paper describes Hantavirus disease and its epidemiology in developed and developing countries, including Indonesia and its recommendation for disease prevention and control
Subclinical Infection by Avian Influenza H5N1 Virus in Vaccinated Poultry
Full text linkHighly 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, vaccinatio
The Role of Triglyceride Lipase, Fatty Acid Synthase and Fatty Acid Binding Protein Family Genes on Fat Metabolism of Broiler Chickens
Full text linkBroiler chicken has high fat content, especially abdominal and subcutan fat which reduced carcass quality and efficiency of feed energy. Genetic approach could be potentially applied to reduce high abdominal and intramuscular fat in broiler chicken through the selection program at gene level related to fat metabolism. This paper describes the metabolism and biosynthesis of body fat and the role of its controlled genes. Fat synthesis is controlled by feed quality and metabolism and biosynthesis process occurred in liver. These processes are controlled by many family genes, but certain genes have dominant role in the process; those are triglyceride lipase genes, fatty acid synthase genes and fatty acid binding protein genes. Expression of fatty acid synthase genes has positive correlation with fat content in liver and intramuscular. Expression of fatty acid binding protein genes was related to the increased abdominal fat deposit. These genes are polymorphic, so that they can be used as a genetic marker in selection to optimize feed efficiency, to minimize abdominal fat and to increase economic value of broiler chicken. Key words: Fat, triglyceride lipase genes, fatty acid synthase genes, fatty acid binding protein gene
