Participation Rate as A Basis for Measuring Food Security Status of Meat
Get PDFFood security has been developed as way for decision makers to pay more attention to this sector. It is believed that foods which are efficiently produced in one area or country may be accessed by other areas or countries. However, this concept is difficult to be implemented since almost none of countries in the world have all resources to produce what is needed by its people. Food consumption, including beef, would be better measured using participation rate which indicates a cluster of its consumer instead of using all population as a denominator for calculating per capita consumption, except for commodities whose consumer member of its cluster close to 100% of the population. For commodities whose consumers less than 50% of its cluster it is more effective to use the size of the cluster as the denominator. Diversified food consumption of animal origin in Indonesia has been indicated by the fact that it has been naturally established. Animal meat consumption diversification for many reasons is influenced by cultural, preferences or other economic status of the households. This phenomena is also indicated by the magnitude of positive cross price elasticity between beef and mutton, beef and poultry meat, and between poultry meat and fish. Therefore, every effort to push higher consumption of one meat type, will reduce the participation rate of others. Susenas data indicated participation rates for beef and buffalo meat were 26.15% (2002), 21.93% (2005), 16.18% (2008) and 16.16% (2011), while poultry meat had higher participation rate as 65.46% (2002), 63.48% (2005), 57.67% (2008) and 56.98% (2011). Application of participation rate approach on the production of beef and buffalo meat resulted in the annual percapita consumption of 6.71 kg (2002), 10.47 kg (2005), 10.82 kg (2008) and 13.11 kg (2011). It concludes that balanced participation rates of meat components (beef and poultry meat), need to be maintained as the existed diversified meat consumption. Effort to increase beef consumption will result in deindustrialization to other meat. Key words: Participation rate, food security, food diversification, mea
Genetic Improvement of Milk Quantity and Milk Quality in Holstein Friesian Cattle by Selection
Get PDFMilk yield and milk quality are essential in determining the development of national dairy industry. Domestic fresh milk is largely produced by Holstein Friesian cows. There is a wide variation of the genetic ability of cows to produce milk or bulls to transmit milk, thus giving the opportunity for the improvement of milk production trait through selection. Milk yield as one of the quantitative traits, in the genetic evaluation, is estimated based on a breeding value. Breeding value can be estimated accurately through appropriate selection methods and by considering various non-genetic factors influencing milk production. This paper focuses the discussion on milk selection methods, which are very commonly done in dairy cattle. To produce superior dairy breeding cattle, selection for the bulls were done by progeny testing method, whereas selection for cows were commonly by individual selection method and their siblings. A number of internal environment factors should be considered in the genetic evaluation of milk production, through the development of appropiate correction factors, thereby increasing the accuracy of the estimated breeding values. The quality of milk especially milk protein contents, in the future, will get more attention from consumers. Therefore, selection should be directed also to improve milk protein components. The existence of major genes controlling on milk protein contents is expected to be the effective way in increasing milk protein yield in domestic HF cow. Selection of superior breeding dairy cattle in producing high milk protein contents is done through the identification of polymorphism of milk protein genes, providing casein and whey family genes. Key words: Holstein Friesian, selection, milk yield, milk protei
Genetically Modified Feed Crops and Feed Ingredients in Indonesia: Opportunities and Constraints of Development
Get PDFThe opportunity of the presence of genetically modified organism (GMO) forage crops in Indonesia is quite large. Although until now there is no single forage crop awarded safely crop in Indonesia, but several crop byproducts have been used as feed ingredient. The controversy over the presence of GMO plant cannot be avoided. There are a part of communities who could not accept the presence of GMO crops for some reasons. On the other hand, the producers claimed the advantages of the GMO crops such as reducing pesticide application, reducing cost of weeding, more tolerant to biotic and abiotic stresses, and increasing production, farmer’s income and welfare. For the opponent, the main concerns are environmental issues and the possibility of emerging diseases in animal as well as human being. The Biosafety Comission through Biosafety Technical Team has the authority to recommend whether GMO food or feed (and plants) is safe or not safe to be consumed and grown in Indonesia after the assessment. Key words: GMO, forage crops, feed safet
The Advantage of Rumen Fluid Collection Technique Using Trocar in Animal Welfare
Get PDFTrocar, a tool to remove the gas in livestock that have bloated stomach, has been modified for rumen fluid collection, as an alternative methods in animal welfare aspects. Rumen fluid collection with trocar modification can be made very easy, cheap and fast at the local sheep, both in vitro and in vivo. After the collection, the trocar does not leave permanent scars because scars on the rumen wall and skin will heal and return to normal. The animal relatively does not suffer from pain and stress; feed intake and body weight do not decrease drastically and animal can live normal. The rumen fluid sampling technique with trocar is better than fistulation in animal welfare aspect. Key words: Animal welfare, fistulation, troca
Merapi Disaster Impact on The Dairy Business in The District of Sleman
Get PDFMerapi disaster with a variety of volcanic material caused fatalities or death and directly influenced on the health of cattle. Both of these effects in addition to psychological effects that cause farmers panic and economically are very harmful. This study aims to analyze the impact of Merapi disaster on dairy cow production and estimate the economic losses on the dairy cattle business. The analysis showed that Merapi disaster caused the death of livestock and reduced milk production. Livestock deaths are mainly caused by hot clouds, lava and ash that consumed through food and the respiratory tract. Decrease in milk production varies from 6.7 percent to 84 percent. Cows that are left displaced and not given food and drink for four days obviously decreased in milk production. The death of livestock, disruption of institutional marketing input and output, falling livestock prices and the decline in milk production resulted in losses IDR. 21.0 billion. Key words: Impact, Merapi eruption, dairy co
Botulism: Pathogenesis, Diagnosis and Prevention
Get PDFBotulism is a potential lethal disease in animals as well as in human, a neuroparalytic disease caused by Clostridium botulinum toxin. C. botulinum is widely distributed in the soil and vegetation, intestinal contents of mammals, birds and fish. Eight types of C. botulinum (A, B, C1, C2, D, E, F, G) have been recognized, each elaborating an immunologically distinct form of toxin. Botulinum neurotoxins are the most powerful biological toxins known and in some countries they have been studied and developed as biological weapon. The medical aspects of the toxin were also developed for therapeutic uses in human diseases. The spores of C. botulinum are relatively heat resistant and in contrast to the spores, botulinum toxin is relatively heat labile. Botulinum toxins are inactivated by their antitoxins. Botulinum toxin produces clinical manifestations when either inhaled or ingested. After toxin is absorbed, it enters the bloodstream and travels to peripheral cholinergic synapses, primarily the neuromuscular junction. Once at these sites, botulinum toxin is internalized and enzymatically prevents the release of acteylcholine leads to paralysis. Laboratory diagnoses for botulism should include isolating C. botulinum and detecting of toxin in the patient. Rapid and sensitive detection of all types of botulinum toxin are needed. Cases of botulism in Indonesia were found primarily in poultry and many cases were suspected and remained undiagnosed. Cases of botulism were suspected affecting cattle in East Java and serologically results showed positive to C. botulinum type C. The botulismus prevention using vaccine induced a strong antibody response and could be remained protective for 12 months, while botulism treatment in animals is usually ineffective.Key words: Botulism, Clostridium botulinum, toxin, diagnosis, preventio
The Relationship of Avian Influenza and Waterbirds in Creating Genetic Diversity and the Role of Waterbirds as Reservoir for Avian Influenza
Get PDFOutbreaks of Avian Influenza (AI) has enormous implications for poultry and human health.These outbreaks are caused by influenza A virus that belongS to the family of Orthomyxoviridae. These viruses are RNA viruses, negative polarity, and the envelope has segmented genom. Generally, Avian Influenza is a disease which originally occurred in birds with complex ecology including reassortment and transmission among different species of birds and mammals. The gene of AI virus can be transmitted among human and avian species as shown by the virus reasortantment that caused pandemic human influenza in 1957 and 1968. Pandemi in 1957 and 1968 were different from previously human viruses because the substitution of several genes are derived from avian viruses. Wild waterfowls especially Anseriformes (duck, muscovy duck and geese) and Charadriiformes (gulls, seabirds, wild birds) are the natural reservoirs for influenza type A viruses and play important role on the ecology and propagation of the virus. From this reservoir, influenza type A virus usually can be transmitted to other birds, mammals (including human) and caused outbreak of lethal diseases. Waterfowl that is infected with influenza A virus usually does not show any clinical symptoms. However, several reports stated that HPAI viruses can cause severe disease with neurogical disorders led to death in waterfowl. Migration of birds including waterfowls have active role in transmitting and spreading the disease. Movement of wild birds and inappropriate poultry trade transportation play a greater role as vector in spreading HPAI to humans. Ecological change of environment has also a great effect in spreading AI viruses. The spreading pattern of AI viruses is usually influenced by seasons, where the prevalence of AI was reported to be in the fall, winter and rainy seasons. Finally, the effective control strategies against the spreading of AI viruses is required. Programs of monitoring, surveilence and vaccination is part of the control strategies of AI viruse spreading besides other strategies that had been applied. Key words: Avian Influenza, reservoir of AI, waterbirds, migratio
Organic Zinc as Feed Additive for Ruminants
Get PDFZinc is an essential micro mineral required by ruminants and is a component of over 300 enzymes which play important role in the metabolisms of carbohydrates, proteins and fats. Recently, the chemical and biotechnology processes have been developed for synthesizing organic Zn. Organic Zn is the product of a chelating process of dissolved Zn anorganic salts with amino acids or hydrolyzed protein. The utilization of organic Zn as feed additive in ruminants diets tends to increase, due to the absorption of Zn in the organic form is more effective than the inorganic form. This paper reviewes the research from comparative studies of inorganic and organic Zn on the growth, production and reproduction in ruminants. The studies found that the supplementation of organic Zn improved nutrient digestibility, growth, feed efficiency, milk production, Zn retention and absorption, production and reproductive performances of ruminants. However, a little variation response was found due to different degrees of chelating on Zn incorporation of amino acids or hydrolyzed protein. Key words: Organic Zn, characteristic, supplementation, performance, ruminant
Prospects of Applying Feed Processing Technologies Based on Industrial Plantation
Get PDFThe potency of plantation sectors (palm oil, sugar cane and cacao) as alternative feed resources for ruminants has been acknowledged since 20 – 25 years ago. However, the level of utilization of these feeds in small ruminant production system has been very low and sporadic. The typical chemical and physical characteristics of most of those feedstuffs required some steps of processing in order to improve their nutritional quality and to ease their handling. Small ruminants, like sheep and goats have relatively higher metabolic energy requirement per kg BW and anatomically have lower gut capacity to process lignocelluose materials compared to large ruminants. It is, therefore, these animals nutritionally face more constraints in handling lignocellulose and bulky materials mostly found in industrial by products or crop-residues from plantations. Physical processes (chopping, phyiscal separation, hydrothermal), chemical processes (ammoniation, hydrolyses and oxidative treatments) and bio-conversions (fermentation, ensiling) have been recommended as alternative technologies in maximizing the utilization of those feedstuffs for small ruminant animals. The principal mechanisms of those treatments are: (i) breaking the linkages between structural carbohydrate and lignin so that it could be easily digested by the animal enzyme systems and (ii) preserving the material from being spoilage due to its high moisture content or for feed stocking purposes. Priorities for choosing the most effective processing technology for implementation or adoption is depent largely on the scale of feed production. Ammoniation, chopping, physical separation, ensiling or bio-conversion are several technologies mostly recommended for small scale operation in situ. These alternative technologies should be able to be adopted by small-holders living around the plantation area. The commercial or large scale feed production could be implemented by the plantation industry by giving high priority to the processing technology such as hydrolitic treatment using NaOH, ammoniation, hydrothermal, pelleting, wafering or cubing. The types of products that possibly produced in this large operation scales are (i) concentrate feed, (ii) complete feed or (iii) basal feeds (roughages). The chain of ruminant feed production systems could be developed further by including the feed industry sector into the system. Within this system the plantation industry will have main role to supply the raw materials for the feed industries. As these local raw materials are readily available, the feed industries could further produce various types of balanced feed or rations based on the principles of feeding standard to meet the nutrient requirements of various classes of ruminant animals.

The Role and Deficiency of Zinc Mineral in Immune System
Get PDFZinc (Zn) is a micro mineral which is needed by every cell in the body. Adequate Zn mineral is important in maintaining optimal health. Zn functions as a cofactor of various enzymes, structural integrity of cells, DNA synthesis, hormonal storage and release, immunotransmision and immune system. Zn deficiency causes decreased appetite, dermatitis, growth retardation, delayed sexual maturation, infertility and imunodeficiency. This is associated with changes in the function of immune system response, such as decreased B and T cell functions, reduced phagocytosis and decreased cytokine production. Severe Zn deficiency is characterized by severely depressed immune function and frequent infections. Zn enhances immune function for specific and non-specific immunity. The role of non-specific immune respone is through the activity of cells phagocytosis by neutrophils and monocytes, while the specific immune response can be humoral and cellular mediated by lymphocytes B and T. Supplementation of Zn can improve the activity of leukocyte cells through stimulating the production of tumor necrosis factor- alpha (TNF-α) by monocytes cells, thereby increasing the ability of phagocytosis. In addition, Zn is also able to increase the production of lymphokines that cause lymphocyte cells able to differentiate and proliferate. Key words: Zn, deficiency, immunity, leucocyte cell
