Anticipation of Emerging Disease Mycoplasma bovis: Prevention and Control
Full text linkMycoplasma bovis is one of the pathogens, causes respiratory, reproductive, mastitis and arthritis disorders in cattle. Due to the economic impact of this disease, Mycoplasma bovis must be free on farms. There are no pathognomonic symptoms of Mycoplasma infection, so it needs laboratory confirmation to diagnose. Many countries have routinely examined M. bovis on cases of mastitis, arthritis, pneumonia and reproductive disorders. There was no cases of respiratory disorder in cattle related to M. bovis infection reported in Indonesia. The fact that, in many countries almost that cases related to the presence of M. bovis. The presence of M. bovis in Indonesia should be investigated, considering that Indonesia imports cattle from Australia and New Zealand that expose to M. bovis. This paper discusses the incidence of M. bovis infection in many countries including its economic impact, clinical symptoms, and method of diagnosis and control of disease to anticipate the emergence of this disease in Indonesia
Coccidiosis Disease in Cattle in Indonesia and Development of Diagnostic Techniques
Full text linkCoccidiosis is a parasitic disease caused by the protozoan of the order Coccidia, the family Eimeriidae of the genus Eimeria which breeds rapidly in the digestive tract and is the most difficult disease to be controlled on cattle farms. Eimeria spp. in cattle can cause high economic losses and increase susceptibility against infectious diseases. Therefore, coccidiosis in cattle needs attention from the government. This paper reviews a number of diagnostic methods that can be used in the detection of Eimeria spp. in cattle based on the goals and objectives of the examination. The coccidiosis cases often do not show any clinical symptoms but can cause sudden death in livestock. The diagnostic method that still used at present is based on its morphology that should not be used in identifying Eimeria species because the morphological characteristics Eimeria spp. have similar shape and size structures between species (resembling morphology). An appropriate diagnostic method for Eimeria is needed in the context of controlling coccidiosis strategically
The Utilization of Insects as Feedstuff in Broiler Diet
Full text linkInsect meal is an unconventional feedstuff and is expected to be an alternative protein source in broiler diet in the future, as an impact of high price and a limited supply of a fish meal. The objective of this paper is to describe the potency of insects as a feedstuff in broiler diet. Some types of insects, i.e., bees, flies, crickets, grasshoppers, termites, ants, and cockroaches have the potential to be a feedstuff protein source. Several studies reported that insect has high protein content (10.3-76.2%). The use of insects as feedstuffs in broiler diet is constrained by several limiting factors, i.e. the presence of chitin, high crude fat content, and the presence of contaminants. Processing insects before being used as feedstuffs is necessary. Separation of chitin and crude fat content are highly recommended before using insect as protein source feedstuff in broiler diet. The use of insects in a broiler diet ranges from 4 to 29.65% depending on the type of insect, life phase of insect and the type of processing. Research and development to increase insect utilization in broiler diet are still needed
Adiponectin: Potential Protein Hormone as a Candidate Biomarker for Male Fertility
Full text linkReproduction is an important factor that requires attention to increase livestock production. The application of artificial insemination (AI) technology has been developed rapidly in the world, so that availability of fertile superior male is a determinant factor of successful AI. Several recent studies have been aimed to discover male fertility biomarker, by intense research on fertility-associated proteins contained in seminal plasma. This paper describes the role of adiponectin as a biomarker candidate of male fertility. Adiponectin has a positive effect on spermatozoa functionality and steroidogenesis. This has been proven by several studies that found its expression in Sertoli cells and Leydig cells in the reproductive tract. Based on the specific role on spermatozoa functionality and steroidogenesis in supporting male fertility parameter, it is strongly suggested that adiponectin is an excellent candidate biomarker for male fertility
Utilization of Biochar and Liquid Smoke to Increase Livestock Performance
Full text linkBiochar and liquid smoke may be utilized as feed additives that potentially used as substitutes for antibiotics. These products are derived from the pyrolysis process that utilizes agricultural, plantation and wood residues. This paper aims to review research results regarding the use of biochar and liquid smoke as feed additives in both non-ruminants and ruminants. Information on the use of of biochar and liquid smoke in livestock are available such as the use of 0.5-1 g bamboo charcoal/ kg goat feed increased growth; addition of 0.2-0.6% corn cobs char to chicken feed showed significant increase in body weight; the addition of 0.6% biochar/ kg feed to local cattle feed increased body weight; the use of activated charcoal containing wood vinegar liquid can reduce cryptosporidiosis in goats and cattle. The opportunity to use agricultural and plantation residues as raw materials for generating biochar and liquid smoke is one of the breakthroughs in realizing the concept of sustainable and environmentally friendly of bioindustrial agriculture. The use of biochar and liquid smoke from agricultural and plantation residues is expected to increase livestock productivity
Melanocortin-4 Receptor (MC4R) Gene as the Main Gene for Rapid Growth Selection in Beef Cattle
Full text linkGenetic 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
Factors Affecting Twinning and the Impacts of Twinning in Cattle
Full text linkEfforts to increase cattle production can be done through increasing the population and productivity of cattle, one of which is through the birth of two offsprings per parent (twin). The incidence of twinning in cattle ranged 1-10%, and influenced by genetic/breed, parity, management, season of breeding. This paper presented factors and technology that increase twinning rate and the impacts of twin births in cattle. There are genetic and non genetic factors affecting twinning rate. Increased twin births can be done through some technologies such as selection, reproduction and management. The problems in twinnings are the high incidence of abortion, early embryonic loss, distochia, retained placenta, metabolic disorders, and ketosis resulting in longer calving interval. Intensive management to dam bearing twins can reduce the problems. Economically, the profits of twinning are different between beef and dairy cattle. Twin births give benefit to beef cattle farming through the increase in total weaning per cattle. The pros and cons of twin births occur in dairy cows farming, especially on milk production
Candidate Gene of Milk Protein for Genetic Improvement of Dairy Cattle
Full text linkThe objective of this paper is to explore some efforts to increase milk protein of dairy cows through a milk protein control gene selection approach. Improving the quality of cow's milk has shifted to increase milk protein levels, due to nutritional and economic interest. The breeding process in producing dairy cattle with the advantage of having high milk protein content is more effectively carried out by molecular biotechnology approaches. The content of cow's milk protein is controlled by cow's milk protein control genes. In the process to produce dairy cattle with the advantage of having high milk protein content, it can be done with a selection approach based on milk protein control genes, namely CSN1S1, CSN2, CSN1S2, and CSN3. Once known, the main controller gene that causes high levels of cow's milk protein, it will be easy to identify dairy cattle that have these advantages, so that the selection of dairy cattle can be done since at early age
Awareness of African Horse Sickness as an Emerging Arbovirus Disease
Full text linkAfrican horse sickness (AHS) is one of the important arbovirus diseases in horse. The disease is fatal and should be transmitted by vector. This disease is potential to spread rapidly and has impacts in public health and socio-economic, especially in the international trade of horses and its products. The paper describes AHS, some factors that influence the disease, how to control the disease and its current situation in Indonesia. African horse sickness has been declared as notifiable disease in OIE list, therefore, the disease becomes strategic in the country that has high horse population. Climate changes affect vector population and spreading of the disease. In order to anticipate the entering of AHS infection in Indonesia, the government needs to facilitate the research on horse diseases including the safe laboratory facilities to handle exotic diseases and provide diagnostic tool for early detection
Biological Characteristics of West Nile Virus and Its Correlation with the Development of Antiviral Drugs and Vaccines
Full text linkWest Nile virus (WNV) is a zoonotic RNA virus. Its genome encodes 3 structural and 7 non-structural proteins. Mutations can occur in both structural and non-structural proteins of the virus. Mutations can enhance the pathogenicity and virulence, but some mutations are beneficial for the development of vaccines. Licensed vaccines are only available for horses, while vaccines for humans are still under development. In Indonesia, WNV infection was detected in 2014 in West and East Java, but vaccines and antiviral drugs in both animals and humans are not yet available. This review describe the characteristic of structural and non-structural proteins of WNV and its correlation with mutations and the development of vaccines and antiviral drugs. Molecular identification and further research is needed to predict, prevent and control WNV infections in vectors, susceptible animals and humans
