Melanocortin-4 Receptor (MC4R) Gene as the Main Gene for Rapid Growth Selection in Beef Cattle Peni Wahyu Prihandini; D Maharani
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 29, No 2 (2019): June 2019
Publisher : Indonesian Center for Animal Research and Development

Genetic improvement for economic traits such as growth is important in beef cattle selection program. This paper discusses melanocortin-4 receptor (MC4R) gene as a candidate gene for rapid growth based on its function, location and pathway, as well as its polymorphism and identified genotypes associated with economic traits, and its application as a marker-assisted selection. MC4R is a prominent gene encoding growth traits and has a critical role in mediating the effect of leptin in regulating food consumption and energy balance. Many identified MC4R gene polymorphisms are associated with growth traits. The MC4R gene, therefore, is considered as a functional candidate gene for growth traits and can be used as a marker in selection program based on molecular genetics. The use of molecular markers such as MC4R gene, therefore, can be applied in genetic improvement program for growth traits in cattle. By using MC4R gene, the efforts to build breeding system in small populations can be proposed. For instance, with an effective population size (Ne) of about 40 heads, the first generation (G1) will be obtained with a composition of GG 61.1%, CG 33.3% and CC 5.6% and male and female ratio of 178:11 and generates ideal Ne of 41 heads. In the third generation, therefore, GG composition will be 100%. The results of molecular analysis can be further used as a guideline in the development and genetic improvement strategies of beef cattle.

The Role Of Milk Peptide As Antimicrobial Agent In Supporting Health Status Eni Kusumaningtyas
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 23, No 2 (2013): JUNE 2013
Publisher : Indonesian Center for Animal Research and Development

Antimicrobial peptide is commonly present in all species as a component of their innate immune defense against infection. Antimicrobial peptides derived from milk such as isracidin, casocidin, casecidin and other fragments with variety of amino acid sequence are released upon enzymatic hydrolysis from milk protein К-casein, α-casein, β-casein, α-lactalbumin and β- lactoglobulin. These peptides were produced by the activity of digestive or microbial protease such as trypsin, pepsin, chymosin or alcalase. The mode of action of these peptides is by interaction of their positive with negative charge of target cell membrane leading to disruption of membrane associated with physiological event such as cell division or translocation of peptide across the membrane to interact with cytoplasmic target. Modification of charged or nonpolar aliphatic residues within peptides can enhance or reduce the activities of the peptides against a number of microbial strains and it seems to be strain dependent. Several peptides act not only as an antimicrobial but also as an angiotensin-converting enzyme inhibitor, antioxidant, immunomodulator, antiinflamation, food and feed preservative. Although the commercial production of these peptides is still limited due to lack of suitable large-scale technologies, fast development of some methods for peptide production will hopefully increase the possibility for mass production. Key words: Peptide, antimicrobial, milk

Manipulating Protein Degradability in the Rumen to Support Higher Ruminant Production Budi Haryanto
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 24, No 3 (2014): SEPTEMBER 2014
Publisher : Indonesian Center for Animal Research and Development

Dietary protein is digested to a certain extent in the rumen causing decreases its potency as source of amino acids for the animal. Dietary protein should mostly reach the intestines where the protein digestion takes place and absorption occurs in the form of intact amino acids and subsequently becomes nutrient deposition in muscles or milk. The higher muscle or milk protein synthesis, the higher the protein in the products of animal, as long as energy for the metabolism is available. Strategies of feeding rumen degradable versus undegradable protein in ruminant have become a research interest for decades. Technologies of dietary protein protection to reduce its degradability in the rumen by heating, chelating or coating have been developed. Key words: Protein, degradability, protection, rumen

The Epidemiology and Control Myiasis in Indonesia S Partoutomo
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 10, No 1 (2000)
Publisher : Indonesian Center for Animal Research and Development

Myiasis caused by screwworm of Chrysomya bezziana fly has been widely distributed in Indoenesia for years, however myiasis as a disease problem is only reported in local cattle raised under semiextensive management system in West Nusa Tenggara, East Nusa Tenggara, South and North Sulawesi. In local cattle raised under an intensive management system in Java, Madura and Bali, disease problems caused by myiasis are unknown. Australian Brahman and Brahman cross cattle which were raised under a ranch system in South Sulawesi and East Sumba, and Merino sheep raised under intensive management system in Bogor and Jakarta are more susceptible to myiasis than local animals. Traditional medicines including tobacco extract, petrol and bettery acid are used for myiasis treatment in the villages, though the scientific background of these medicines are remained unknown. Insecticides and pesticides in the form of ointments are considered more effective against screwworm than in the form of spraying particles, the reasons for this being that C. bezziana flies do not stay long on the body of animals except whilst laying their eggs. Some drugs including ivermectine and methoxychlor are also effective against screwworm. Key words : Myiasis, Chrysomya bezziana, screwworm, epidemiology

Agro by-Product Fermentation Product as Poultry Feedstuffs Tiurma Pasaribu
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 17, No 3 (2007): SEPTEMBER 2007
Publisher : Indonesian Center for Animal Research and Development

Feed is the main component in livestock industry, and contributes 70% of the total farming cost. Agriculture by-product is one of the alternative feed ingredients for poultry feed, but unfortunately they have low in nutritive value and high fiber contents that inhibit metabolism process. Fermentation technology is one of the methods to improve the nutritive value and to decrease fiber content of agriculture by-product. This paper explains the process of technology fermentation process and the effect of fermented product on poultry. Fermented agriculture by-product can be offered 5 to 30% depend on substrates and species of poultry without causing death. Fermentation process is not difficult to do, therefore agriculture by-product fermentated product are potential as poultry feedstuffs. Key words: Agriculture by-product, technology of fermentation, fermented products, poultry

Application of Technology on Improving Beef Cattle Productivity in East Nusa Tenggara Wirdahayati R B
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 20, No 1 (2010): MARCH 2010
Publisher : Indonesian Center for Animal Research and Development

The Province of East Nusa Tenggara (NTT) had been one of the major beef cattle suppliers under traditional management system in Indonesia. The beef cattle farming that based on grazing native pasture and the introduction of shrub legumes (Leucaena leucocephala) may contribute to around 15 – 50% of the farmers’ household income. In the last few years, supply of beef cattle tended to decline due to the decrease in cattle population in NTT. Some basic improvements in management and feeding toward increasing beef cattle productivities had been carried out in Nusa Tenggara, such as a baseline survey on Cattle Health and Productivity Survey (CHAPS) conducted in 1990 – 1992. The objective of the program was to identify the existing beef cattle productivity and health condition throughout Nusa Tenggara. A collaborative research with the Ministry of Research and Technology (Integrated Prime Research) had also been carried out and the result showed that early weaning in Bali calves that can be practised as early as 3 – 6 months to prevent calves losses during the dry season. A program of the Assessment on Beef Cattle Base Farming Activities had also been conducted to improve fattening and breeding practices through the improvement in beef cattle management and feeding systems. At the latest development, fattening scheme has been introduced under a partnership approach involving private sectors and cooperatives. This needs to be facilitated by the government to accelerate the program such as access to capital and intensive extension services to build farmers awareness toward profit oriented beef cattle farming. Optimalization of the available potential resources and technology in NTT, will be an opportunity to enhance beef cattle production and gains back the reputation as one of the major producing beef cattle in the past. This will also support the national livestock program nowadays, called Beef Cattle Self Sufficiency Program 2014. Key words: Beef cattle, productivity, technology, East Nusa Tenggara

Publisher : Indonesian Center for Animal Research and Development

Palm oil estates is very large in Indonesia, predominantly in North Sumatera, Riau and South Sumatera provinces. The production of by-products such as palm oil leaf (POL); palm oil fronds (POF); solid ex decanter (SED) and palm kernel cake (PKC) are 17,1 tons; 486 tons; 840−1260 kgs; 567 kgs in dried form per-hectar per-year respectively. A number of research showed that the utilization of these by-products are potential as energy and protein source for cattle and sheep and can reduce 20-40% of feeding cost compared to conventional concentrate diet. According to 70−80% of total production cost are feed cost, there fore using these by-products give an agreat opportunity to integrate the animal production with palm estate as an agribisnis scale. The plantation area that have an oil palm industry is the main opportunity for establishing the integration production system. The feed industry can be run efficiently, because by-products can be supplied by oil industry directly. Key words: Integration, palm oil, livestock, by-products

Fowl Cholera and Its Control Prospect With Locally isolated Pasteurella multocida Bivalent Vaccines Tati Ariyanti; Supar .
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 18, No 1 (2008): MARCH 2008
Publisher : Indonesian Center for Animal Research and Development

Pasteurellosis or fowl cholera disease which associated with Pasteurella multocida group A and D infections occurred sporadically in many parts of the world, including in Indonesia. The pathogenic activity of P. multocida in chickens were based on lipopolysacharide (LPS) antigens associated with group A and D capsules, and the resistance factor of complement mediated bacteriolysis in animals. In order to reduce common bacterial infections, antibiotics were routinely used as feed additive or by drinking water, but fowl cholera cases still occur. Fowl cholera control by vaccinations have been used more than a hundred years ago by means of inactive vaccine, but imported inactive vaccine was reported not effective due to lack of cross protection against heterologous serotype. At present, many local P. multocida isolates from chicken and ducks from many areas in Indonesia were characterised for their antigenicity, immunogenicity and prepared as monovalent or bivalent vaccine. Only the monovalent vaccine prepared from BCC 2331 or DY2 demonstrated the presence of immunoprotection against homologous and heterologous challenged with live bacteria. The prototype bivalent vaccine consisting of BCC 2331 + DY2 demonstrated high degree of cross protection against challenged individual with or mixed of BCC 2331 + DY2 at average of 60 – 75% and 75 – 100%, respectively. Monovalent and bivalent vaccine prepared from other isolates including imported reference strains of P. multocida demonstrated no protection in experimentally vaccinated ducks and chicken against challenged with live bacteria of neither BCC 2331 nor with DY2. From these retrospective studies, it was concluded that the local isolates P. multocida designated as BCC 2331 and DY2 could be used as candidates of prototype vaccine or master seed vaccine but their effectiveness still need to be evaluated under field conditions. Key words: Pasteurella multocida, Indonesian isolates, inactive vaccines, fowl cholera

Based on rumen degradation rate, concentrates are divided into : slow degraded energy feeds, fast degraded energy feeds, slow degraded protein supplements, and fast degraded protein supplements. This classification is important to synchronize the presence of nutrients in the rumen used to stimulate rumen microbes growth . Rumen microbes-can be used as protein supplements for the host . Protein content, digestibility, and biological value of rumen microbes are about 65%, 75-85%, and 80%, respectively . Rice straw as an agricultural by product has a low protein content of not more than 7%, low digestibility, thus in the digestive tract, in rumen, and particle changes in rumen require about 81 .67 hours, 62.69 hours, and 1 .62% per hours, respectively. Rice straw utilization as feed needs supplementation and quality and digestibility improvement in the form of physical, chemical, biological, or combined. The physical treatment aims at reducing particle size or cell swelling . Reducing particle size of roughage will increase the rate of passage in the rumen, increase consumption, decrease digestibility, and reduce milk fat, while sodium hydroxide treatment will increase digestibility up to 100% without nutrient increase, however it is dangerous to human life and a pollutant for the agriculture field. Rice straw treatment using ammonia increase its digestibility and its nutrient . The biological treatment was conducted to change rice straw structure by enzyme lignocellulase and increase protein content with microorganism. Basically, the concept of biological treatment is restricted composing, conservation, and predigesting to increase quality. Recently, many commercial products have been developed for rice straw biological treatment orienting at predigesting of cellulose. The application of physical, chemical, and or biological treatment for agricultural by product is as component for complete feed Key words: Rumen Microbes, supplementation, predigesting

WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 19, No 1 (2009): MARCH 2009
Publisher : Indonesian Center for Animal Research and Development

Feed supply is getting limited since the use of land for forages has been replaced by building industries big plantation, agriculture. Sustainable integration between animal and food crop and plantation is efficient and gives advantage for both. Rice, cassava soybean, groundnut, palm oil, coconut, coffee, cocoa and sugar cane are food crop and plantation which their byproducts are generally used or modified/processed for ruminant production. This paper describes optimization on the use of these byproducts to decrease feed cost without ignoring the feed quality. These byproducts have special characteristic and limitation with fluctuated price. Their nutritive values vary and they can be grouped into fiber, fiber-energy, fiber-protein, protein or energy sources. Therefore, special strategy for each location and purpose of livestock industry is required to get an efficient and optimal feed composition. Key words: Feed, agriculture byproduct, beef cattle
