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.

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.

Positive Effect

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.

Positive Effect

Fodder methionine is one of the most important amino acids in animal nutrition, and its deficiency in the ration negatively affects productivity. Currently, the following sources of methionine are represented on the Russian market of feed additives: DL-Methionine and Methionine Hydroxy. Liquid form — Methionine Hydroxy Analog Free Acid (MHA-FA) and dry (for example, МНA) — calcium salt (MHA-Ca2+). The most popular sources of dry methionine are DL-Methionine and hydroxy analog as calcium salt. Many sources state that the bioavailability of the hydroxy analog varies from 65 to 72% (one of the manufacturers of the commercial hydroxy analog claims that the availability of methionine is 84%). The experiment was carried out on broiler chickens. As a result of the studies carried out, it can be argued that the content of DL-methionine in the ration (in the amount of 65% of the hydroxyanalogue) in comparison with MHA-Ca increases the productivity of broilers: preservation – by 4%; live weight by 4.3%; average daily gains by 4.6%; feed conversion decreased by 7.1%; has a positive effect on meat productivity. Based on the data obtained during the experiment, it follows that the efficiency of MHA-Ca does not exceed 65%, compared to DL-Methionine.

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.

The objective of the research is to investigate effects of phytogenic additives as broiler feed supplements on production and slaughtering performances, morphological parameters and caecal microflora of fattening chickens of Ross 308 provenance. The research was based on two trials. In both trials, two feeding treatments were studied: a control diet with no supplemental feed additives (K) and a diet with a phytogenic additive supplemented to the control diet (1000g/t of Biomin PEP 1000, during the whole period). In the first trial, a total of 304 chickens were studied, in two treatments with four repetitions per pen with 38 chickens. The second trial included 16800 chickens, and it was conducted as a macro trial, that is, a pen with 8400 chickens was the subject of the trial. The results have shown that the chickens fed with the supplemental phytogenic additive have achieved significantly more favourable feed conversion rate. Differences in body mass and mortality rate between the trial group and the control were not statistically significant. Phytogenic additives did not have significant effects on breast portion and abdominal fat. Adding the phytogenic additive did not have significant effects on morphological parameters, but there was a tendency to increasing villous height and crypt depth. In both trials, the chicken groups fed with the supplemental phytogenic additive had less of all investigated groups of bacteria, and the differences were statistically significant for Enterobacteriaceae and Staphylococcus in the first, and Enterobacteriaceae and Enterococcus in the second trial. It can be concluded that the diet with the supplemental phytogenic additive had a positive effect on broiler performances, jejunum morphology parameters and caecal microflora.

The article presents our research results of the influence of various additives-sorbents on the broiler chickens meat productivity. Currently, the fight against mycotoxins in feed and the syndrome of sudden broilers death at the final stage of fattening is an urgent problem. In the conditions of a poultry farm in the northern region of the Republic of Belarus an enriched zeolite-containing component based on tripoli was introduced into the broiler chickens mixed feed. At the end of the technological period of growing the cross "Ross-308" broiler chickens the comparative effect of feed additives "Vami-Lactulose" and "Kiskad" on their meat productivity was studied. It was found that the feed additives introduction had a positive effect on the absorption of feed nutrients and their assimilation by the poultry body as well as the blocking and elimination of toxic components. In the end, the energy of the consumed feed contributed to the formation of broiler chickens high meat qualities. In the production conditions an increase of the 1st grade carcasses yield in the experimental groups by 2.2-3.7% was recorded which had a positive effect on the poultry meat production efficiency. During the anatomical cutting of carcasses an increase in the meat indices of broilers of the experimental groups was recorded compared with the control including offal output of the category 1, slaughter output, the output of the gutted carcass, edible parts, muscles as a whole and individual muscle groups. There were no significant differences in organoleptic indices in the samples of poultry meat of the control and experimental groups. The relative biological value of meat obtained from experimental broiler chickens was higher in the pectoral muscles by 6.2-6.9 %, femoral - by 7.0-8.6% and liver - by 7.4-8.8 %. Based on the conducted production tests on the introduction of mycotoxicosis prevention in the agro-industrial complex with new zeolite-containing feed additives it was established that the feed additives "Vami-Lactulosa" and "Kiskad" developed by us contribute to the stimulation of broiler chickens meat productivity and the production of environmentally friendly food. Meat of the experimental groups poultry is of good quality and meets the requirements of international standards (GOST and STB).

A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of the control group.

European Ash

During the recent decades, the ascomycete Hymenoscyphus fraxineus has been spreading across Europe causing dieback of ash and threatening existence of the species. Still, several studies have suggested positive effect of stand diversity on ash health condition. The aim of this study was to evaluate effect of stand composition and structure on ash health condition in young stands in Latvia. Among the tested stand properties, number of shrub species and tree height were the best linear predictors of ash health condition, yet their effect differed between the provenance regions. In the eastern part of Latvia, number of shrub species in stand showed positive relationship with ash health, while taller trees displayed worsening health condition. In the western pat of Latvia, the relationships were inverse. Such differences in biotic relationships might be related to differences in climate, hence development of the pathogen, and/or genetically determined susceptibility of different populations of ash.

This article presents a method for determining the microflora of the blind processes of the intestines of broiler chickens receiving heterologous lactobacilli with anti-C.jejuni activity as a feed additive in comparison with intact chickens. In the course of a scientific and production experiment on the Cobb 500 cross broilers, an experiment was carried out to determine the total number of bacteria in the intestinal contents by quantitative PCR. Sequencing was performed on a MiSeq genomic sequencer (Illumina, Inc., USA) using the MiSeq Reagent Kit v3 kit (Illumina, Inc., USA). Data were obtained on the total number of bacteria and their taxonomic diversity. As a result of the studies, it was shown that the microflora of broilers throughout the entire maintenance period corresponded to the norm. The use of feed additives based on lactobacilli in general had a positive effect on the state of microflora of the blind processes of the intestine..
