<p>The authors have investigated the effect of different sources of metonin in the diets of quails on their productivity and carcass quality. Experimental studies were carried out with Pharaoh quails in Problematic Research Laboratory of Feed Additives in the National University of Life and Environmental Sciences of Ukraine. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form; young birds were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations with different sources of metonin (<em>DL-</em> metonin<em>,</em> <em>L-</em>metonin <em>and МНА)</em>).</p><p>We have found that compound feed with the <em>L-</em>metonin contributes to live body weight increase by 5.3% or 13 g, average daily growth by 5.9 % or 0.37 g, reduces feed conversion by 2.1%, increases the mass of not gutted carcass, semi gutted carcass and gutted carcass of 12.5 (6.2%), 12.5 (6.2%), and 10.5 g (6.4%); increases the mass of pectoral muscles and muscles of the pelvic limbs by 7.37 and 6.49 g (18.2% and 24.5%) and mass of liver by 0.94 g. Use of diets with<em> </em>MНA and DL-methionine did not significantly effect the productivity and carcass quality, whereas entry to the diet of MNA increased feed conversion by 5.4%. During the study period the safety of livestock which was fed with different sources of metonin ranged from 93 to 96%.</p><p>We believed the further research are needed to examine the impact of different sources of metonin on the egg production of egg-laying quails, morphological and chemical composition of eggs and their hatching quality.</p>

<p>The authors have investigated the effect of different levels guanidinoacetic acid in the diets of quails on their productivity and carcass quality. Experimental studies were carried out in the conditions of the problematic research laboratory of feed additives in the National University of Life and Environmental Sciences of Ukraine. Material for scientific and economic experience was quail of Pharaoh species of meat direction of productivity. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form. Young animals were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations. The effect of using different levels of Guanidinoacetic Acid (GAA) in compound feed on productivity and carcass quality of young quails was studied. We have found that compound feed with the level of GАА 0.06% contributes to live body weight increase by 3.9 g and muscles of the pelvic limbs yield by 26.2%. At the same time, use of diets with a level of 0.12% of guanidine acetate increases live weight by 13.5 g, the absolute growth of 6.5 g, average daily growth by 0.9 g, a relative growth of 2%, the mass of carcass, semi-eviscerated carcass, and eviscerated carcass of 4.8, 4.9 and 4.3% correspondingly, slightly increases the mass of pectoral muscles by 9.1%, significantly increases the yield of muscles of the pelvic limbs by 36.4%, and reduces feed conversion by 5%. Poultry which was fed with 0.18% of GАА exceeded control of body weight by 12.2 g, the absolute growth by 4.4 g, average daily growth by 0.6 g, the relative growth by 1.1%, yield of muscles of the pelvic limbs by 36.4% and  had a lower feed conversion rate by 9.1%. During the study period the safety of livestock which was fed with GААvwas high and ranged from 90 to 96%.  It was established the perspective of further research, which is to examine the impact of Guanidinoacetic Acid on the egg production of egg-laying quails, morphological and chemical composition of eggs and  their hatching  quality.</p>

There is a need for newer feed additives due to legal prohibition on inclusion of growth promoting antibiotics in livestock diets in several countries due to antimicrobial resistance. In this context, rare earth elements (REE) have gained attention among animal nutritionists as potential growth promoters. Currently, several studies have reported better weight gain, milk production, egg laying capacity and feed conversion efficiency among different breeds of farm animals following supplementation with REE, with however largely inconsistent results. Furthermore, REE supplementation has also shown to improve ruminal fibrolytic and proteolytic activities as well as flavor of meat with negligible residues in edible tissue, however the mechanism behind this action is still unclear. According to existing research, due to their poor absorption and similarity with calcium REE might exert their action locally on gut microbial populations within the gastrointestinal tract (GIT). Moreover, REE have also shown anti-inflammatory, anti-oxidative as well as immune stimulating effects. The present review aims to broaden the knowledge about use of REE as feed additives for livestock and sum up efficacy of REE supplementation on performance and health of animals by comparing the findings. Till date, researches with REE have shown properties that make them a promising, new and safe alternative feed additive but further exploration is recommended to optimize effects and clarify discrepancy of various results before practical proposals can be drafted.

Abstract. The purpose of the research is to develop an effective feed additive with an optimal content of raw protein in combination with flavoring additives for ducklings, which allows to increase zoo technical and economic indicators with broiler technology of fattening young animals. Research methods. A scientific and production experiment was conducted on three groups of analog ducklings from a daily age to 49 days old. The studied indicators are: the dynamics of live weight by fattening phases, absolute and average daily growth, the safety of young animals, feed conversion, slaughter indicators, the European fattening efficiency indicator, the profitability of meat production. Results. The use of compound feeds with an optimal level of protein content in combination with flavoring additives prepared on the basis of developed feed additives intended for fattening broiler ducklings in the fattening phases contributes to an increase in: live weight by 11.4 %, the safety of young animals by 3 %, feed consumption and conversion by 3.9 and 7.6 %, slaughter yield of 1.1 %, the European fattening efficiency indicator from 246 to 308 units and the profitability of meat production by 24.5 %. Scientific novelty. For the first time, a complex feed additive has been developed, which, according to the age periods of fattening, includes three varieties: “Prestart”, intended for intensive fattening of young animals from daily to 10 days of age inclusive, “Start” for ducklings from 11 to 21 days and “Finish” from 22 to 49 days. The rate of introduction of the additive is 30 % of the mass of mixed feed. The composition of the supplement includes high-protein feeds, premixes, amino acids and flavoring substances (monosodium glutamate, acetic and citric acids, a mixture of phytogenics: oregano, cinnamon, red pepper).

In the article, results of researches on an establishment of an optimum source of Manganese are resulted. Manganese was additionally added mixed fodder for quails grown for meat. Experimental studies conducted in terms of problem research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. Independent experiment was conducted with growing Pharaoh Coturnix quails. We conducted a randomized block experiment with 3 treatments, each with 4 replicates of 25 growing birds (1 to 35 d of age). A diet consisting of corn, soybean and sunflower meal, wheat, fish meal, sunflower oil, premix (28% CP, 2.88 kcal of ME/g on 1 to 21d of age, 20.5% CP, 2.97 kcal of ME/g on 22 to 35 d of age) having severally Manganese sulphate, Manganese glycinate and Manganese citrate. Diets and water were offered ad libitum. After 5 weeks of dietary treatments the carcass composition (breast muscles, leg muscles, skin, subcutaneous fat, liver, kidneys, lungs, heart, gizzard) were affected by dietary treatments. Carcass weight and breast muscles was increased (P < 0.05) with organic sources of manganese in the diet. It found little effect (P = 0.053) sources of manganese in the fodder for eviscerated yield. Therefore, Manganese glycinate could be used as a good tool for improving carcass yield of quails.

The article presents the expediency of using valine in the feeding of growing quails of meat direction of productivity. The studies were conducted in the conditions of research laboratory of feed additives of National University of Life and Environmental Sciences of Ukraine. The experiment was conducted with growing Pharaoh quails. It was selected 500 daily quails. Birds were placed in 20 cages with 25 heads in each. In the formation of analog groups, the body weight of the birds was taken into account. Quails were fed full-fledged mixed fodder, which was balanced by energy and other nutrients. The feed for the quails of the control group contained the natural level of valine, and the experimental groups – additionally L-valine according to the experimental scheme. Observed a relationship between the level of valine in feed and feed conversion (R2 = 0.7359). The most effective level of valine in mixed fodder for quail, which is grown for meat, to obtain a sufficiently large body weight with a low level of feed intake per unit of growth is at 1– 21-day age – 1.68% and at 22– 35-day age – 1.23%.

Tracking the capability of the egg production industry to supply the food industry with enough cage-free eggs to meet retailers' and restaurants' animal welfare commitments is important to industry groups and farm animal advocacy organizations alike. In this project, we synthesize an analysis-ready data set that tracks cage-free hens and the supply of cage-free eggs relative to the overall numbers of hens and table eggs in the United States. The data set is based on reports produced by the United States Department of Agriculture (USDA), which are published weekly or monthly. The data will be updated periodically as new USDA reports are released. We supplement these data with definitions and a taxonomy of egg products drawn from USDA and industry publications. The data include flock size (both absolute and relative) and egg production of cage-free hens as well as all table-egg-laying hens in the US, collected to understand the impact of the industry's cage-free transition on hens. Data coverage ranges from December 2007 to present. Initial analysis of cage-free trends shows that, as of the most recent version of this report, 26% of all table-egg-laying hens lived in cage-free systems. This figure represents an increase of 23 percentage points over the entire sample period of December 2007 to April 2020.Revised: May 29, 2020

The potential honey supply available in the Republic of Uzbekistan can have up to 2 million bee families. For the development of the beekeeping industry in Uzbekistan, it is necessary to create a purebred population of Apis mellifera carpatica, based on the reproduction of early purebred queen bees. In addition to protein fi llers and mineral complexes, probiotics were used as part of stimulating feed additives for autumn and spring stimulation of egg production of queen bees. However, in our opinion it is better to add prebiotics to the composition of feed additives, which are available in the composition of infant formula used for baby food. It has been established by studies that stimulating feed additives with protein fi llers, combined with cobalt sulfate and a mixture of “Nanny 2 with prebiotic” positively infl uence on the growth, development and economically useful traits of maternal, paternal and queen-rearing colonies in preparation for winter. It has been proved that a high rate of growth of the brood being grown is carried out when giving honey satiety in the composite form with CoSO4 + “Nanny 2 with prebiotic” mixture. In comparison with the background level, this parameter reaches its maximum by the third accounting, increasing in maternal families by 2,41 times, in paternal families – 2,61 times, in queen-rearing colonies – 2,61 times. It has been found that the Carpathian queen bees showed their high genetic capabilities for egg production during the autumn increase in the strength of families with the 3rd and 4th variants of feed additives until the end of the experiment. The maximum rate of egg laying females recorded in the 4th group, exceeded the same level of the 1st group of the parent families by 1,44 times, 2nd group – 1,24 times 3rd group by 1,14 times. An adequate pattern has been registered for paternal and queen-rearing colonies. Stimulating feed additives in particular, the use in group 4 of honey additive in a composite form with CoSO4 + mixture of “Nanny 2 with prebiotic” has a prolonging eff ect, both on the egg-laying ability of queen bees, and on brood feeding, which increases the strength of bee families. By the beginning of winter, this force was 15,4 and 16,0 seams of bees between two combs in the maternal families, 15,5 and 15,8 seams of bees between two combs in the paternal families, and 15,8 and 16,0 seam of bees between two combs in the queen-rearing colonies, respectively. This indicates that a complete generation of autumn bees will be obtained, which will not only successfully overwinter, but will also be actively used in the breeding of extra early queen bees in the new season.

Results from the South Australian Random Sample Tests in the period 1966 to 1978 were analyzed to determine if there had been any changes in the average performance of commercially available egg production strains. Average age at sexual maturity was found to have declined by about 0.5 days per year, and eggs per hen housed to have increased by about 1.7 eggs per year during the period analyzed. Non-linear trends were detected for feed consumption, feed conversion efficiency and income over feed and chick costs. For hen-day egg production, a non-linear upward trend was apparent with the most rapid progress having been made in the latter part of the period analyzed.

As probiotics, fungi enhance animal health and are suitable animal feed additives. In addition to brewing fungi, there are also edible and medicinal fungi. Common fungi utilized in feeding programs include Saccharomyces cerevisiae, Aspergillus oryzae, Pleurotus spp., Antrodia cinnamomea, and Cordyceps militaris. These fungi are rich in glucans, polysaccharides, polyphenols, triterpenes, ergosterol, adenosine, and laccases. These functional components play important roles in antioxidant, anti-inflammatory, anti-obesity, and immune system regulation. As such, fungal feed additives could be of potential use when breeding livestock. In previous studies, fungal feed additives enhanced body weight and egg production in poultry and improved the feed conversion rate. Several mycotoxins can be produced by hazardous fungi but fortunately, the cell walls constituents and enzymes of fungal probiotics can also act to decrease the toxicity of mycotoxins. Overall, fungal feed additives are of value, but their safety and usage must be studied further, including cost-benefit economic analyses.
