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.

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.

In recent years, there has been a steadily growing demand for animal protein. Consumer awareness is also growing every year, which is why breeders are obliged to provide animals with the best possible environmental conditions that will determine the productivity of animals and the quality of raw materials obtained from them. Today's consumer is looking for not only the highest quality food but also the one that will characterize health-promoting properties. Therefore, food is sought, which will be characterized by a favorable profile of fatty acids and a high content of biologically active ingredients, such as vitamins or minerals. One of the most effective methods of enriching food with these ingredients is their supplementation in feed. However, it should be remembered that the form in which such a component will be delivered is very important. High hopes are associated with the possibility of using organic forms of macro- and micronutrients, which are sometimes better absorbed than inorganic salts. The aim of the work was to collect and systematize knowledge related to the possibility of enriching food of animal origin with micronutrients using additional feed containing these ingredients in organic form.

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.

The quality of raw materials and goods of animal origin depends first of all on the safety of feed, their balance in terms of the main nutrients and digestibility by the body. As a rule, the lower the quality and safety of feed, the lower the productivity of all types of animals and poultry. The quality of feed is influenced by all stages of their production: growing conditions, harvesting and storage, processing technologies, canning and preparation for feeding. Where high-quality feed is used in diets, maximum productivity and high realization of the genetic potential of animals are obtained. During the storage and processing of plant and animal raw materials its physic and mechanical, biochemical, sanitary and microbiological properties change. This can be avoided only by observing the sanitary and hygienic requirements for bagging, harvesting, and storing feed. The quality of feed is confirmed by its physical, chemical, organoleptic, microbiological and other indicators, which determines the variety of feed control methods at all stages of their turnover. In this connection, the development and strengthening of control over the quality and safety of feed and feed additives is one of the important tasks of modern animal feeding science. The purpose of the work was to carried out a comparative assessment of four samples of the starting compound feed SK-3 for piglets of different producers. The experimental part of the work has been carried out in the laboratory of veterinary expertise at the compound feed plant LLC “Athens-Volga”. For the study of compound feed an average sample was taken from each sample, separating from the combined sample using a hand scoop according to Federal standard 13496.0-2016. Methods of sampling. Quality and safety control was carried out according to organoleptic, physic and chemical, microbiological indicators and the content of mycotoxins in compound feed. Monitoring of compound feed of the compared samples of the starting compound feed for piglets SK-3 according to the studied indicators has shown that all samples meet the sanitary and hygienic requirements of Federal standard of our country.

Demands for higher production and consumer demand for healthier food have encouraged intensive research for alternative animal growth promoters in recent years. Research trends are focused on the development of new products enriched with feed additives to improve animal health and enhancing production. Many of these compounds are unstable in the presence of light, air, water, or high temperatures and need to be protected during processing, storage, and application. By encapsulatied in microparticles, feed additives are protected from harmful external influences, and their stability and functionality are not diminished. Microencapsulation technology is used to protect payload and improve bioavailability by controlled and targeted delivery to the digestive tract. It is particularly suitable for the addition of feed additives in ruminant’s nutrition, because the correct choice of microparticle material allows the release of the feed additives in the small intestine, and not in the rumen. With proper use, microparticle formulations are an effective tool in animal nutrition that delivers nutrients and/or drugs to a specific site at the desired rate. The paper summarizes laboratory studies on the application of microencapsulation technology in feeding ruminants and monogastric animals. Numerous results of the application of encapsulated feed additives have shown a positive effect on animal health, increased productivity without negative effects on the final product, and environmental protection.

Meat, milk, and egg contribute positively to the nutrition and health of humans; however, livestock requires a large number of resources, including land for fodder and grains. Worldwide millions of tons of vegetable waste are produced without any further processing, causing pollution and health risks. Properly managed vegetable waste could provide a source of feed for livestock, thus reducing feeding costs. In this regard, pumpkin waste (Cucurbita sp.) is an alternative. Research on pumpkin waste on animal nutrition is scarce, however, it has potential as animal feed not only for its nutritional value but also for its antioxidants, pigments, and polysaccharides content that could enhance quality of meat, milk, and egg, as well animal health. In this review, we describe the environmental impact of livestock as a result of greater demand for food of animal origin, including the importance of the consumption of animal foods in human nutrition and health. Moreover, we emphasize the potential of plant residues and, particularly, on the characteristics of pumpkins and how their use as feedstuff for livestock could improve productivity and modify the composition of meat, milk, and egg.

Various animal feed products may influence animal health, conversion of animal feed into food of animal origin and the emissions caused by animals. All these matters are regulated in the directives of the European Food Safety Authority (EFSA). This chapter first discusses EFSA guidance on how to compile dossiers for feed additives. The chapter then discusses key issues and steps in demonstrating the efficacy of new animal feed products: reduction of nitrogen (N) excretion, reduction of feed contamination of by mycotoxins and, finally, reduction of methane emissions with feed additives. Key steps, such as the use of in vitro and in vivo studies, to test the effects of feed additives are discussed in detail.

The evaluation of the quality of Veterinary Inspection in Poland has received much attention in the past few years. Veterinarians working as Food Inspectors face numerous and newly arising problems in the protection of animal health status, providing surveillance information on the occurrence of diseases, and carrying out risk analyses of the hazards related to food of animal origin. From the 130 active veterinarians attending the post graduate courses in “Hygiene of slaughter animals, meat and animal origin products” in Poland, 119 took part in the survey. The questionnaire consisted of 15 questions that delivered information on demographic features of the respondents, and various aspects of the course of their work: (a) Motivation to undertake work in food safety sector, (b) overall job satisfaction, (c) crucial negative factors and (d) occupational hazards. Participants were mainly under 40 years of age. They were Veterinary Food Inspectors working as Official and Approved Veterinarians. Permanent position and economic reasons were their main motivation in the food safety sector. They indicated problems related to insufficient training in ante and post mortem examination, work with legal acts and risk analysis. They also declared a lack of preparation in coping with crisis situations. One third of the respondents declared their health and lives were endangered, while fulfilling professional duties and pointed at different sources of hazards. The overall evaluation of the work in food safety sector was rated good and satisfactory.


This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.
