Plant tannins are widely found in plants and can be divided into hydrolyzed tannins and condensed tannins. In recent years, researchers have become more and more interested in using tannin-rich plants and plant extracts in ruminant diets to improve the quality of animal products. Some research results show that plant tannins can effectively improve the quality of meat and milk, and enhance the oxidative stability of the product. In this paper, the classification and extraction sources of plant tannins are reviewed, as well as the biological functions of plant tannins in animals. The antioxidant function of plant tannins is discussed, and the influence of their structure on antioxidation is analyzed. The effects of plant tannins against pathogenic bacteria and the mechanism of action are discussed, and the relationship between antibacterial action and antioxidant action is analyzed. The inhibitory effect of plant tannins on many kinds of pathogenic viruses and their action pathways are discussed, as are the antiparasitic properties of plant tannins. The anti-inflammatory action of tannins and its mechanism are analyzed. The function of plant tannins in antidiarrheal action and its influencing factors are discussed. In addition, the effects of plant tannins as feed additives on animals and the influencing factors are reviewed in this paper to provide a reference for further research.

<p class="awabstrak2">The climate in Indonesia as a tropical country is very condusive for the growth of mycotoxins producing fungi. Mycotoxins have properties as carcinogenic, mutagenic, teratogenic, estrogenic, neurotoxic, and immunotoxic. Mycotoxins reduce performance, appetite, weight, and immunity. They also cause reproductive disorders and generate the residues in animal products that affect human health. These can be prevented by controlling mycotoxins contamination in agricultural products that used for feed ingredients through good management practices (during planting, harvesting, and storage). Mycotoxins contamination can also be minimized by physical, chemical and biological treatments as well as the application of mycotoxin binders. This review describes the use of mycotoxin binders in animal feed. They are used as feed additives, may be derived from organic, inorganic materials or their combination. Combination of organic and inorganic substances proven to be more effective and efficient in controlling mycotoxin contamination. Therefore, it is recommended to use mycotoxin binders to prevent animal health disorder and to decrease mycotoxin residues in animal products.</p><p class="awabstrak3"> </p>

Animal has a direct impact on the quality of meat, milk and eggs in a positive and negative sense. Over the composition of a meal for animals can manipulate the quality of products of animal origin and can be achieved by a variety of nutritional, sensory, chemical, physical and physiological characteristics. The use of medicine in intensive and extensive farming is a big and risky to the quality of food and thus health. In organic farming of animals is not allowed to use medicines. Because are increasingly looking for natural healing resources. Herbs provides, in the manufacture of animal feed, a real opportunity to increase value through the use of different functional additions. Addition food for animals, really can improve its functionality in terms of a physiological effect. In developed countries in Europe is very strong trend of replacing synthetic antibiotic drugs based on medicinal herbal preparations. As herbal feed additives may be used drug (finely divided dry medicinal herbal raw materials), herbal extracts or herbal isolate (e.g. essential oil). The paper gives a short overview of the most important potential of herbal medicinal materials with antibacterial activity, antiinflammatory, digestion-stimulating, laxative, antidiarrhoeal, choleretic etc. activities that have an approved application in human medicine and which can be added to animal feed for use in different animal health disorders. The use of herbs is more current and all higher, in human and veterinary food industry.

Microbiological Status

Sushi is a traditional Japanese food, mostly consisting of rice and raw fish. Fish is considered a healthy food, but as with other animal products, consumption of raw muscle incurs potential health risks such as ingestion of pathogenic bacteria or parasites. In this study, 250 sushi samples were analyzed for their microbiological status and the prevalence of pathogenic bacteria. A comparison was made between frozen sushi from supermarkets and fresh sushi from sushi bars. Aerobic mesophilic bacteria counts differed for sushi from these two sources, with means of 2.7 log CFU/g for frozen sushi and 6.3 log CFU/g for fresh sushi. The prevalence of Escherichia coli and Staphylococcus aureus was higher in the fresh samples. Salmonella was found in four (1.6%) of the sushi samples, and Listeria monocytogenes was found in three (1.2%) of the samples. These results indicate that the microbiological quality of industrially processed sushi is higher than that of freshly prepared sushi. The quality of freshly prepared sushi strongly depends on the skills and habits of the preparation cooks, which may vary.

Main Factor

At present we obtain the stable increasing of livestock milk productivity in Russia, but in the same time there is reduction of cows number and deficit of milk production that resolved only by import for 15–25%. The main factor, limited the gain of milk production volumes, is low quality of bulky feeds, the base of livestock rations, the portion of which is compound more than 50% on nutritiousness. Moreover, bulky feeds determine the type of feeding, quantity and quality of including mixed concentrate fodders, bio-additives and feed additives in diets. Experience of advanced specialized farms shows, that Holstein cows able to give 10–12 thousand kg of milk during lactation, whereas Ayrshire cattle — 7.5–8 thousand kg of milk if silage and haylage in diet conforms to requirements of 1 category and contains not less 10 MJ of metabolized energy (9 MJ for hay) and more than 14% of crude protein. Low quality of balky feeds is compensated by exceeding of concentrates in diets, that due negative influence on animal health and decrease the terms of their productive use to 2–2.5 lactations. The enhancing of bulky feeds quality is possible at state supporting of milk branch and realization the complex measures in farms, directed on application the advanced technologies of forage crops cultivation and harvesting, effective approaches of its processing and preservation.

It has been established that introducing feed additives to livestock, either nutritional or non-nutritional, is beneficial in manipulating the microbial ecosystem to maintain a balance in the gut microbes and thereby improving nutrient utilization, productivity, and health status of animals. Probiotic use has gained popularity in the livestock industry, especially since antimicrobial growth promoter’s use has been restricted due to the challenge of antibiotic resistance in both animals and consumers of animal products. Their usage has been linked to intestinal microbial balance and improved performance in administered animals. Even though monostrain probiotics could be beneficial, multistrain probiotics containing two or more species or strains have gained considerable attention. Combining different strains has presumably achieved several health benefits over single strains due to individual isolates’ addition and positive synergistic adhesion effects on animal health and performance. However, there has been inconsistency in the effects of the probiotic complexes in literature. This review discusses multistrain probiotics, summarizes selected literature on their effects on ruminants, poultry, and swine productivity and the various modes by which they function.

Bioactive Substances

<p>Bioactive compounds (phenols, tannins, flavonoids, essential oils, curcumin, saponins, phyllanthin) have the ability as an antibacterial or antifungal. Feed additives are feed raw materials that do not contain nutrients, however, it may increase productivity, quality of livestock products (meat, eggs, milk, skin, feathers), the feed efficiency and to improve animal health or resistance of disease. Feed additives that are widely used in the livestock industry include antibiotics, antioxidants, antifungals, emulsifiers, and binders. The aim of using antibiotics is to reduce the population of pathogenic microbes or disturbing microbes in the digestive tract. Antibiotics have been banned for used because it can cause resistance to pathogenic bacteria or intestinal microflora which has a negative impact on consumers. To improve feed efficiency in poultry and to produce higher quality products, healthy and safe for consumption, the antibiotic could be replaced with plant bioactive compound. The aims of this review is to describe the role of plant bioactive compounds as feed additive to replace antibiotic for chickens. Some of plant bioactive substances that can be used as feed additives include phenols, curcumin, saponins, tannins, phenols, flavonoids, alkaloids. Bioactive substances from plants have several functions including inhibiting the growth of bacteria or fungi, increasing endurance, as an adjuvant, and preventing fat oxidation. It can be concluded that bioactive substances from plants have potential as feed additives which have the ability as antibacterial, antifungal, antioxidant, immunostimulator, and adjuvant.</p><p>Keywords: bioactive compound, plants, feed additives, chicken </p><p> </p><p><strong>Abstrak</strong></p><p> Zat bioaktif (fenol, tanin, flavonoid, minyak atsiri, curcumin, saponin, phyllanthin) memiliki kemampuan sebagai antibakteri atau antifungi.

Food Of Animal Origin

To attain better feed utilization, longer preservation, easier manipultion and higher production and better quality of food of animal orgin as the final goal, besides raw materials, feed mixes contain numerous pronutrients (additives), added to perform different effects, in a narrower sense, the term pronutrient implies heterogenous substances, which have no diverse effects and have to be efficient in the manner of use. Basically, all pronutrients have to reach the goal of keeping optimal animal health status and to increase production of food of animal origin without adverse and negative effects. The development of biotechnology had a great part in the appearance of natural alternatives which are able to fulfil and satisfy the high demands of highly productive animals, as well as those of the consumer lobby and environmental protection movements. Growth promoters based upon physiological mechanisms and production potential of the animal have an unquestionable adventage, not only because of the lack of residues in food of animal origin; but also because of their ecological safety and decrease of envirnomental pollution by undigested materials. Demand continues to grow for "all natural", non-pharmaceutical feed additives with growth enhancing effects in food animals. Special attention is paid to minerals (anorganic and organic sources), growth stimulators (antibiotics, probiotics prebiotics), substances for better feed utilization (enzymes, acidifers) adsorbents.

In 2007, the aim of an Ányos Jedlik program and call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants – in this case: vitamin E and lycopene – used as feed-additives can increase the antioxidant content of milk. The milk with anincreased level of vitamin E and lycopene content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E as feed-additive can significantly increase the amount of vitamin E in the milk. The use of lycopene as feedadditive also gave good results. At the beginning of the experiment, the lycopene content of the milk was below the detection limit, while in the post-feeding milk samples the lycopene became detectable. Based on our results, we are of the opinion that further experiments and analyses are needed regarding the quality of food of animal origin and animal health.
