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.

By Products

With the increase in world food demand, the output of agricultural by-products has also increased. Agricultural by-products not only contain more than 50% dietary fiber but are also rich in functional metabolites such as polyphenol (including flavonoids), that can promote animal health. The utilization of dietary fibers is closely related to their types and characteristics. Contrary to the traditional cognition that dietary fiber reduces animal growth, it can promote animal growth and maintain intestinal health, and even improve meat quality when added in moderate amounts. In addition, pre-fermenting fiber with probiotics or enzymes in a controlled environment can increase dietary fiber availability. Although the use of fiber has a positive effect on animal health, it is still necessary to pay attention to mycotoxin contamination. In summary, this report collates the fiber characteristics of agricultural by-products and their effects on animal health and evaluates the utilization value of agricultural by-products.

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.

AbstractSmall ruminants represent an important economic source in small farm systems and agriculture. Feed is the main component of livestock farming, which has gained special attention to improve animal performance. Many studies have been done to improve feed utilisation through addition of feed additives. For a long period, antibiotics have been widely used as growth promoters in livestock diets. Due to their ban in many countries, search for alternative feed additives has been intensified. Probiotics are one of these alternatives recognised to be safe to the animals. Use of probiotics in small ruminant nutrition has been confirmed to improve animal health, productivity and immunity. Probiotics improved growth performance through enhancing of rumen microbial ecosystem, nutrient digestibility and feed conversion rate. Moreover, probiotics have been reported to stabilise rumen pH, increase volatile fatty acids production and to stimulate lactic acid utilising protozoa, resulting in a highly efficient rumen function. Furthermore, use of probiotics has been found to increase milk production and can reduce incidence of neonatal diarrhea and mortality. However, actual mechanisms through which probiotics exert these functions are not known. Since research on application of probiotics in small ruminants is scarce, the present review attempts to discuss the potential roles of this class of feed additives on productive performance and health status of these animals.

AbstractThe use of metal nanoparticles as supplements of animal diets does not always bring unambiguous results. There are many reports in the literature about the multifaceted effects of this type of supplementation on the animal organism. Therefore, the aim of the paper is to present the current knowledge of the possible application of nanometal forms in animal nutrition and its potential benefits and threats. The positive effect of nanoparticles used as feed additives has most frequently been reflected in an increase in body weight, higher average daily gain, or improvement of the FCR value. In some cases, however, the effect of nanoparticle addition to diets was indiscernible. The potent antibacterial activity of nanoparticles, especially against Gram-negative bacteria and Gram-positive bacteria, is regarded as a positive effect. In turn, the probability of their toxicity is a potential risk in application thereof. Supplementation of diets with nanometals has been accompanied by pathological changes in animal tissues, primarily in the pancreas, kidney, liver, rumen, abomasum, small intestine, adrenal glands, and brain. Additionally, at the the cellular level, nanoparticles were found to induce toxicity, inflammatory excitation, and cell death. Oral administration of nanoparticles induced a risk of malfunction of the nervous system and even impairment of cognitive processes in animals. The increasing knowledge of the possible toxic effects of nanoparticles on the animal organism suggests caution in their use in animal production and necessitates further precise investigations in this area.

One of the most industrialized animal production branches of ruminant production successfully requires a blending of theoretical knowledge of nutritional principles with practical stockmanship, maintaining health and dealing with numbers. It is well known that high yielding, dairy cows, require balanced diet with adequate nutrients for yielding. This is not provided with only a few feedstuffs. Milk production in dairy cows is related to the improvements in genetic merit of farm animals and also developments in feed science, feed technology and animal nutrition. In particular, feeds and feed technology studies associated with sustainability, economical perspectives and product quality in the last decade have been in advance. In the present work, recent advances in feed sources and feed technology, minerals (macro and trace minerals ), vitamins and amino acids, feed additives (antibiotics alternative growth stimulants, rumen modulator, organic acids, antioxidants, enzymes, plant extracts), nutrition-products (meat-milk-progeny) quality and functional food production (milk, meat) nutrition-reproduction, nutrition-animal health, nutrition-environmental temperature, nutrition-global warming were evaluated.

Seaweeds comprise ca. 12,000 species. Global annual harvest is ca. 30.13 million metric tonnes, (valued ca. $11.7 billion USD in 2016) for various commercial applications. The growing scope of seaweed-based applications in food, agricultural fertilizers, animal feed additives, pharmaceuticals, cosmetics and personal care is expected to boost market demand. Agriculture and animal feed applications held the second largest seaweed market share in 2017, and the combined market is anticipated to reach much higher values by 2024 due to the impacts of current research and development targeting enhanced animal health and productivity. In general, seaweeds have been utilized in animal feed as a rich source of carbohydrates, protein, minerals, vitamins and dietary fibers with relatively well-balanced amino acid profiles and a unique blend of bioactive compounds. Worldwide, the animal nutrition market is largely driven by rising demand for poultry feeds, which represents ca. 47% of the total consumption for all animal nutrition. This review provides an overview of the utilization of specific seaweeds as sustainable feed sources for poultry production, including a detailed survey of seaweed-supplemented diets on growth, performance, gastrointestinal flora, disease, immunity and overall health of laying/broiler hens. Anti-microbial effects of seaweeds are also discussed.

Antibiotic Growth Promoters

The term gut health is currently becoming more important for domestic animals including poultry. Gut health refers to the fundamental organ system which covers multiple positive functions like effective digestion, stabilizing intestinal microbiota, gut pH and modulation of effective immune response. Gut health depends on proper balance of microbial population. A wide range of feed and pathogen associated factors influence this balance, and adversely affect the animal health status and production performance. Antibiotic stimulators have been used in farm animals to achieve maximum production. But drug resistance and residual effects of antibiotics in animal products (milk, meat and egg etc.) have raised serious issues in human life. Therefore, The European Union (EU) has strictly banned the application of antibiotic stimulators in livestock nutrition in several others countries including China. As a result, an alternative to antibiotic growth promoters are required to support the profitable and sustainable animal production system. Probiotics as nutraceuticals has been categorized as an alternative natural feed supplement for commercial utilization. Such products have been recognized as safe feed additives in animal industry. Very few studies have comparatively described the effect of probiotics on gut health of domestic animals. Therefore, the aim of this review is not only to explore the beneficial effects of probiotics in improving gut health of domestic animals as an alternative to antibiotic growth promoters, but also to evaluate the probiotics associated health and risk factors, and to provide comprehensive scientific information for researchers, scientists and commercial producers.

Abstract The strength of leg bones is not only genetically determined but it also depends on the gender, age, health condition and nutrition of slaughter birds. Calcium ions deficit in bones results in the deterioration of skeleton structure and reduction of bone strength. The presented work compiles the results of studies concerning the effect of feed additives on the level of calcium in the bones of broiler chickens, published during the past 10 years. From the analysis of available literature it follows that some additives had a positive effect on the accumulation of calcium (e.g. vitamin D, probiotics, prebiotics and synbiotics), some were not very explicit (e.g. ascorbic acid and phytase), while others did not have a significant effect on the accumulation of calcium in bones (e.g. herbs and chelates). It is concluded from our collected information that the use of probiotics, prebiotics and synbiotics offers the best advantages for poultry. These additives, apart from stimulating the accumulation of calcium in bones, also benefit animal health.
