The use of enterosorbents and chelate compounds as feed additives in animal nutrition in local areas of technogenic load

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.

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.

Phytic acid is the main storage form of organic phosphorus. Due to its structural features, phosphorus in phytate is inaccessible for assimilation by animals. Moreover, remaining inaccessible reservoir of phosphorus for animal nutrition, phytic acid is capable of forming insoluble complex salts, which lead to soil and water pollution. Мicrobial enzymes - phytases, capable of decomposing phytic acid to organic phosphorus are being used as feed additives in animal nutrition to solve this problem. Thus, search and development of technologies for the production of enzymes on an industrial scale are the most urgent. Methylotrophic yeast P. pastoris are widely used in biotechnology, as an efficient system for the recombinant proteins expression. They have many advantages, including rapid growth on inexpensive media, a wide range of molecular tools for genetic manipulation in optimizing production processes, they are safe for humans and animals, carry-out many post-translational modifications and produce recombinant proteins intracellularly or extracellularly within a short period of time. It was found that the recombinant P. pastoris strains pPINK-LC-α-MF -phyC, pPINK-HC-α-amyl -phyC, pPINK-LC-α-amyl -phyC, pPINK-HC-α-MF -phyC are able to produce and to secrete B. ginsengihumi bacterial phytase M 2.11 phyC. The maximum activity was observed in the pPINK-LC-α-MF strain – 2.6 (U / mg). Recombinant B. ginsengihumi M 2.11 phytases exhibited high activity in a wide pH range from 2.5 to 9.0. The MF-phyC-HC construction is pH stable. The temperature optimum of all recombinant phytases corresponds to 37 ° C; recombinant phytases retain their activity in the range from -80 to 90C.

In this review article the use of algae as feed in animal nutrition is being examined. The algae evolved on earth 3.5 billion years ago. They are primitive, generally aquatic and photosynthetic organisms, which range in size from 0,2-2,0 μιτι in diameter -microalgae (phytoplankton) up to 60 m length- macroalgae and may divide once or more per day. Algae are classified using a combination of characteristics in the chlorophyta, phaeophyta, chrysophyta, rhodophyta (all of them are macroalgae), pyrrhophyta and cyanophyta (they are microalgae). The chemical composition of algae varies over a wide range and depends on environmental conditions. Algae are necessary in the reduction of greenhouse gas emissions. They can be used as biodisel from their bio-lipid oil, as feed additives (alginates, carrageenans, agar, pigments), as therapeutic agents, as cosmetics, as organic fertilizer. Moreover, edible algae are considered sources of minerals and a complementary source of food protein for human -especially infunctional foods and animal nutrition, both in ruminants and monogastric animals. Algae in the rations of lactating cows increased milk production, the average milk protein, the amount of lactose, and prolonged the lactation period, while algae rich in (n-3) fatty acids effected positively on this fatty acid content of milk. In calves the dietary algae en-hanced immune function and improved carcass characteristics. Regarding the ewes, the algae nutrition affected milk fat composition and their dairy products. Researches on monogastric animals showed that the dietary supplementation of algae rich in docosqexaenoic acid increased its content in muscle tissue of rabbits, heavy pigs (live weight around 160 kg) and in the egg yolk of laying hens. In addition, algae in poultry diets can be used effectively as pigment sources both in egg yolk and in broiler skin and shanks. Algae have been found also to be a valuable food for fish farmed by acquaculture. However, further investigation is needed concerning the use of algae in human and animal nutrition.

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.
