Rhizopus sp is a type of fungi which easily grow in the soil, fruit, vegetables and fermented food. This paper describes some functions of Rhizopus sp on increasing nutritional value of feed ingredient and possibility of its application in Indonesia. Rhizopus mold has been known in Indonesia especially for tempe production for food. Research about Rhizopus sp gives knowledge for utilizing Rhizopus sp for other functions. Rhizopus sp is able to inhibit the growth of toxigenic fungus, Aspergillus flavus and to degrade aflatoxin. Rhizopus sp also produces compounds which are able to inhibit pathogenic bacteria and acts as antioxidant. Rhizopus sp absorbs some minerals and changes them to become organic minerals hence it increases mineral absorption by the body. Utilization of feed fermented by Rhizopus sp in livestock showed better result compared to non fermented feed. Rhizopus sp is also very potential to be applied as feed additive for livestock.
根霉是一种容易生长在土壤、水果、蔬菜和发酵食品中的真菌。本文介绍了根霉在提高饲料成分营养价值方面的一些作用及其在印尼应用的可能性。根霉在印度尼西亚已经为人所知,尤其是在食品的豆瓣生产中。对根霉的研究为利用根霉发挥其他功能提供了知识。根霉能够抑制产毒真菌黄曲霉的生长并降解黄曲霉毒素。根霉还产生能够抑制致病菌并起抗氧化剂作用的化合物。根霉吸收一些矿物质并将其转化为有机矿物质,从而增加身体对矿物质的吸收。根霉发酵饲料在家畜中的应用效果优于未发酵饲料。根霉也很有潜力作为家畜饲料添加剂。

Based on the last national livestock census in 2013, the population number of cattle and buffalo have reduced by 15% compared to that in 2011. The highest reduction happened in Java that reached around 24-27%, while that in Bali and Nusa Tenggara was 25%. One of the reasons was caused by decreasing number of cows due to the increase of productive cows slaughtered every year. Number of cows slaughtered in Bali, Nusa Tenggara, and South Sulawesi had reached on average of 72% from total slaughtered, where more than 90% were productive cows. Reasons for slaughtering productive cows were due to: (1) Lower cows price; (2) Limited bulls supply; (3) Local government regulation on inter-island trade; (4) Weak and inconsistent law enforcement; and (5) Lack of understanding on criteria for productive cows by farmers. Increased rate of slaughtered cattle and increasing rate of inter-island trade volumes that higher than the rate of cattle population had caused the decrease of national cattle population. There are currently needs to improve and develop operation slaughter-houses under management of local state enterprise. The management applies on certain mechanisms that sort of incoming productive females according to different grades into allowable to be slaughtered and selected for breeding females, which could be further traded inter-island as supplier of cows for other regions. This strategy may help the central government to meet the demand for productive cows, particularly in Sumatera and Kalimantan which have abundance of feed biomass resources. Policy support is needed as instruments for all interested stakeholders including those who are willing to invest in cattle development such as oil-palm estates.
根据2013年的上一次全国牲畜普查,与2011年相比,牛和水牛的种群数量减少了15%。减少幅度最大的是爪哇,约为24-27%,而巴厘岛和努沙登加拉则为25%。其中一个原因是,由于每年屠宰的多产牛数量增加,奶牛数量减少。在巴厘岛、努沙登加拉和南苏拉威西,屠宰的奶牛数量平均达到总屠宰量的72%,其中90%以上是多产的奶牛。屠宰高产牛的原因是:(1)奶牛价格较低;(2)多头供应有限;(3)地方政府对岛屿间贸易的监管;(四)执法不力、执法不一致;(5)农民对奶牛生产标准缺乏了解。肉牛屠宰率的增加和岛间贸易量的增加高于牛种群数量的增加,导致了全国牛种群数量的减少。目前需要完善和发展地方国有企业管理下的经营性屠宰场。该管理采用一定的机制,将进入的有生产能力的母牛按不同等级分类为允许屠宰和选择繁殖的母牛,这些母牛可以进一步在岛间交易,作为其他地区的奶牛供应商。这一战略可能有助于中央政府满足对高产奶牛的需求,特别是在拥有丰富饲料生物质资源的苏门答腊和加里曼丹。需要政策支持作为所有感兴趣的利益相关者的工具,包括那些愿意投资于油棕庄园等畜牧业发展的人。

Characteristics of double muscled growth in animals are influenced by myostatin gene (MSTN). Myostatin gene is known as a member of the growth gene's superfamily (TGF-β) which works to suppress the muscle growth. However, the presence of six mutations on MSTN cause the gene inactive, and trigger the occurrence of muscle hypertrophy. Identification of myostatin gene was conducted by molecular techniques, and the most common method is polymerase chain reaction followed by single-strand conformation polymorphism (PCR-SSCP). Research on sheep and goat in several countries showed that there had been several variations occurred in myostatin gene but further studies are required to correlate these variations to body weight gain and other important production parameters. For goat production in Indonesia, myostatin mutations cause double muscling that can be utilised for genetic improvement in goat breeding plan to produce a new breed with high quality meat.
肌生长抑制素基因(MSTN)影响动物双肌生长的特性。肌生长抑制素基因是生长基因超家族(TGF-β)的一员,其作用是抑制肌肉生长。然而,MSTN上的6个突变导致该基因失活,并引发肌肉肥大的发生。肌生长抑制素基因的鉴定采用分子技术,最常用的方法是聚合酶链反应+单链构象多态性(PCR-SSCP)。在一些国家对绵羊和山羊进行的研究表明,肌肉生长抑制素基因发生了几种变异,但需要进一步研究这些变异与体重增加和其他重要的生产参数之间的关系。在印度尼西亚的山羊生产中,肌肉生长抑制素突变导致双重肌肉,可用于山羊育种计划的遗传改良,以生产出具有高品质肉质的新品种。

Dadih is a product of fermented buffalo milk in a bamboo tube from West Sumatera. The decline of buffalo population in West Sumatera caused dadih scarcity. The demand of dadih is high because it is an integral part of the Minangkabau’s diet and culture. Cow milk can be used as a substitute of buffalo milk for producing dadih , although the product has slightly different characteristics, especially lower total solids. Producing cows milk dadih similar to buffalo milk dadih, fresh cow milk should be concentrated and added with skim milk. Single or combination of lactic acid bacteria from the genus Lactobacillus , Lactococcus , Streptococcus and Bifidobacterium from dadih of buffalo milk or commercial culture can be used as a starter. Based on investment analysis, the prospect of developing cows milk dadih is feasible.
Dadih是来自西苏门答腊的竹筒发酵水牛奶的产物。西苏门答腊水牛数量的减少导致了大面积的短缺。dadih的需求很高,因为它是米南卡保饮食和文化的组成部分。牛奶可以代替水牛奶生产dadih,尽管该产品的特性略有不同,尤其是总固体含量较低。生产牛奶大堤类似于水牛牛奶大堤,新鲜牛奶应浓缩并添加脱脂牛奶。来自水牛奶或商业培养物的dadih的乳酸杆菌属、乳球菌属、链球菌属和双歧杆菌属的乳酸菌的单个或组合可以用作发酵剂。通过投资分析,发展奶牛奶业的前景是可行的。

Poultry, especially broiler is an important protein source for people in developing countries. Under intensive condition, economical and efficient broiler production is disturbed by disease attack due to poor biosecurity management. Feed additives (coccidiostat and antibiotic growth promoter/AGP) that added to feed for disease prevention and growth improvement, have been banned by many countries including Indonesia. Antibiotic growth promoter can be substituted by bioactive compounds in certain plants which can improve poultry production. One of bioactive compounds is saponin which is a glycoside. This paper provides information about source and function of saponin as feed additive for poultry production. Saponin extracts or saponin containing plants have several functions, such as anticoccidia, immunostimulant, antibacteria and antifungi. Sustainable poultry production requires continues supply of feed ingredients and additive with consistent in quality. High saponin-containing plants need to be planted widely and supported by stakeholders for their avability and sustainability.
家禽,尤其是肉鸡,是发展中国家人民的重要蛋白质来源。在集约化条件下,由于生物安全管理不善,经济高效的肉鸡生产受到疾病侵袭的干扰。添加到饲料中用于预防疾病和改善生长的饲料添加剂(球虫抑制剂和抗生素生长促进剂/AGP)已被包括印度尼西亚在内的许多国家禁止。某些植物中的生物活性化合物可以取代抗生素生长促进剂,从而提高家禽产量。皂苷是一种糖苷类生物活性化合物。本文介绍了皂素作为家禽饲料添加剂的来源和作用。皂苷提取物或含有皂苷的植物具有多种功能,如抗球虫、免疫刺激剂、抗菌和抗真菌。可持续的家禽生产需要持续供应质量稳定的饲料原料和添加剂。高皂苷植物需要广泛种植,并得到利益相关者的支持,以确保其可用性和可持续性。

Milk productivity is highly dependent on inputs used in the dairy farm. The limited source of forage or native grasses with low nutritional quality reduce production and reproduction of dairy cows. Improvement of feed quality can be conducted by various ways, including fortification and supplementation with specific substances that have the potency to increase milk production. This paper describes the potency of local plants, nutritional and bioactive substances that can be utilized to improve production and quality of milk. Some of these plants are cassava ( Manihot sp), torbangun ( Plectranthus amboinicus (Lour) Spreng) and katuk ( Sauropus androgynus (L) Merr) leaves which are potential as feed supplement for cows, goats, and buffalo. The high protein bypass and galactogogue compounds content in these plants are factors increasing production and quality of milk.

Genetic improvement in beef and dairy cattle which can increase meat and milk production can be conducted through livestock selection based on molecular technique using leptin gene. The leptin gene is located on the fourth chromosome and consists of three exons and two introns. The leptin gene serves to produce the leptin hormone secreted by fat tissue. High concentrations of leptin hormone can increase feed intake and body metabolism thereby increasing livestock productivity. This paper describes the leptin gene including structure, mechanism of leptin hormone and polymorphisms in cows. These polymorphisms occur in the promoter, intron and exon sections associated with body and carcass weight and milk production in some cattle breed. Therefore, leptin gene can be used for selection towards increasing cattle productivity. Utilization of leptin gene can be done by single nucleotide polymorphism (SNP) identification on the whole structure of leptin gene and to observe its effect on characteristics of cattle production in Indonesia.
利用瘦素基因,通过分子技术选择家畜,对肉牛和奶牛进行遗传改良,提高肉牛和奶牛的产奶量。瘦素基因位于第四染色体上,由三个外显子和两个内含子组成。瘦素基因的作用是产生脂肪组织分泌的瘦素激素。高浓度瘦素激素可增加采食量和机体代谢,从而提高牲畜生产力。本文介绍了奶牛瘦素基因的结构、产生瘦素激素的机制及其多态性。在某些牛品种中,这些多态性发生在与体重、胴体重和产奶量相关的启动子、内含子和外显子部分。因此,瘦素基因可用于提高牛生产能力的选择。通过对瘦素基因全结构的单核苷酸多态性(SNP)鉴定,观察其对印尼牛生产性状的影响,可以对瘦素基因进行利用。

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.
通过饲喂高淀粉、低纤维的高精料饲粮,提高反刍动物的能量摄入,达到最佳生产性能。然而,据报道,消化系统疾病即瘤胃酸中毒的流行是这种喂养策略的缺点。这鼓励农民和营养学家在饮食中提供足够的纤维,以满足最低的膳食纤维需求。然而,据报道,饲喂高粗饲粮会对生产性能产生不利影响,从而给农民带来经济损失。因此,一些人工纤维的应用已经被引入,以减少营养性疾病的风险,并提高反刍动物的生产力。利用瘤胃机械刺激器是为了维持高精料饲粮反刍动物健康的瘤胃功能。本文综述了近年来反刍动物瘤胃机械刺激器(一种替代饲料物理功能的伪纤维)的研究进展。本文综述了瘤胃机械刺激器在奶牛、肉牛和绵羊中的应用,特别关注反刍时间和瘤胃参数。综上所述,瘤胃机械刺激器通过对瘤胃壁进行机械刺激,可最大限度地减少高精料饲养引起的代谢问题。

Nowdays, people prefer to consume safe and healthy food such as organic food and milk. Organic milk comes from organic farms applying sustainable environment and animal welfare. Consumers choose organic milk because it provides health benefits and comes from farm that applying animal welfare and green environment. Organic milk contains no pesticide residues, antibiotics and other contaminants. This paper describes the comparison of conventional and organic dairy farm and the quality of organic milk in terms of nutrition and contaminant. Organic farming that implements a production system for premium market with special requirements of production process and product quality, demands high management qualification. The difference between organic and conventional milk is the higher level of conjugated linoleic acid (CLA) because of rich forage feed in an organic livestock raising system.
现在,人们更喜欢食用安全健康的食品,如有机食品和牛奶。有机牛奶来源于应用可持续环境和动物福利的有机农场。消费者之所以选择有机牛奶,是因为它对健康有益,而且来自应用动物福利和绿色环境的农场。有机牛奶不含农药残留、抗生素和其他污染物。本文介绍了传统和有机奶牛场在营养和污染物方面的比较,以及有机牛奶的质量。有机农业是对生产工艺和产品质量有特殊要求的高端市场生产体系,对管理资质要求很高。有机奶和传统奶的区别在于,在有机畜牧系统中,由于饲料丰富,共轭亚油酸(CLA)含量较高。

In terms of epidemiology, the distribution of anthrax globally remains enzootic, and is endemic in some parts of Indonesia. Contact with anthrax spores that present in meat, soil and grass can cause disease in both humans and animals. This paper describes risk factors causing high prevalence of anthrax, also attitude and knowledge of farmers’ community toward anthrax. Several risk factors that causing high prevalence of anthrax transmitted to humans are lack of farmers’ knowledge on anthrax, people's habit of slaughtering the sick animal and consuming the meat for economic reason. The knowledge of anthrax amongs farmer communities are influenced by education level, information sources, and professions. Farmers community knowledge in Indonesia towards anthrax is relatively low. Most farmers have wrong perception that anthrax is non-contagious disease. Control of anthrax in livestock and humans will be effective, if the community has better knowledge, attitude and good perception of disease. Interventions need to consider both technical and social (local knowledge and culture, as well as community behavior) factors to be appropriate and more acceptable to farmers and local communities.
在流行病学方面,炭疽在全球的分布仍然是地方性的,在印度尼西亚的一些地区是地方性的。接触存在于肉类、土壤和草中的炭疽孢子可导致人类和动物患病。本文介绍了炭疽热高流行的危险因素,以及农民社区对炭疽热的态度和知识。造成炭疽热向人类传播的高流行率的几个危险因素是农民缺乏对炭疽的知识,人们出于经济原因屠宰病畜并食用其肉的习惯。农民社区的炭疽知识受教育程度、信息来源和职业的影响。印度尼西亚农民社区对炭疽的知识相对较低。大多数农民错误地认为炭疽是一种非传染性疾病。如果社区有更好的知识、态度和对疾病的良好认识,牲畜和人类炭疽的控制将是有效的。干预措施需要考虑技术和社会(当地知识和文化以及社区行为)因素是否合适,是否更容易为农民和当地社区所接受。
