For the normal life of laying hens and their egg production not only good conditions and a properly balanced diet are necessary, but also the presence of vitamins and minerals in the feed in the right amount. The purpose of this work was to study the eff ectiveness of using the feed additive Supervita-M in the diets of laying hens. The research has been carried out under the conditions of LLC “Nizhnevartovskaya poultry Farm” on laying hens of the industrial herd of the cross High-Line Brown. Egg production of laying hens during the experiment period was higher in the experimental group by 3 %. The intensity of egg production in the experimental group that received the feed additive Supervita-M was also higher than in the control group. According to the yield of egg mass per average laying hen, the best results have been obtained in the experimental group, they exceeded the similar indicators of the control group by 0,6 kg. When tested the weight of the egg obtained from the experimental hens was in the range of 60–61 g. At the end of the experiment there was a noticeable increase in this indicator in laying hens that received the vitamin and mineral additive in addition to the main diet. The experimental group exceeded the control group by 8,3 % by egg weight. Positive results have been obtained for the livability of laying hens. This indicator in the experimental group was higher by 6,6 % compared to the control group. Analysis of the blood parameters of laying hens has shown that the use of the additive aff ected the increase in red blood cells. So, at the beginning of the experiment this indicator was 2,2–2,5×10[sup]12[/sup]/l, and at the end – 3,8–3,9 ×10[sup]12[/sup]/l.

At the present time of the development of industrial poultry farming, the main tasks are to increase the productivity of poultry, reduce production costs and improve its quality. Under practical conditions, there is a shortage of minerals in compound feed for poultry, which leads to a violation of metabolism in the body, slowing down growth and development, deterioration of the work of organs and systems, a decrease in productivity and its quality, and an increase in the prime-cost of production. The purpose of the research was to study the effectiveness of the use of the feed additive “Toxinon” in feeding of replacement young chickens and laying hens. The research has been carried out under the conditions of OOO “Bogotolskaya Poultry Farm” in the Bogotolsky area in the Krasnoyarsk Territory. Comprehensive studies have been conducted to study the effect of the feed additive “Toxinon” on the growth and development, productivity and metabolism of replacement young chickens and laying hens of the industrial herd of the cross “Haysex brown”. The influence of different dosages of the feed additive “Toxinon” on the growth rate, livestock livability, digestibility and use of feed nutrients, egg productivity, egg quality, hematological and biochemical blood parameters of replacement young chickens and laying hens has been studied. The laying hens of the 3rd experimental group were distinguished by the highest egg productivity during the experiment period, which exceeded the control group in terms of the gross number of eggs by 6,4 %, the intensity of egg production by 5,02 abs.%, egg weight by 3,0 % (P > 0,95), the yield of egg mass on the average laying hen by 9,12 %. At the same time, expenditures of feed in the 3rd experimental group have decreased compared to the control group by 7,3 % for 10 eggs, by 9,2 % for 1 kg of egg mass. It has been found that in feeding replacement young chickens and laying hens, the most effective use of the feed additive “Toxinon” in the dosage of 0,25 % of the weight of the feed mixture (2,5 kg/ton of feed).

Poultry farming is one of the major branches of animal husbandry, which develops through concentration, specialization and intensification on the basis of poultry plants and poultry farms. The increase in production of eggs and poultry meat is based on a significant increase in the productivity of poultry with a simultaneous increase in its population with a high payment of feed by production and the increase in labour productivity. The purpose of the work was to study the influence of enzyme feed additives in the diets of laying hens on the quality of eggs. The researches have been carried out in PJSC “Poultry plant Chelyabinskaya”, which produces high-quality chicken eggs obtained from the poultry cross “Loman LSL-classic”. The object of study was enzyme drugs produced by Sunzyme – a multi-enzyme drug that includes xylanase, cellulase and mannase activities. The dosage of enzyme drugs in the feed mixture of laying hens was: Sunfyze 5000 – 80 g/t, Sunzyme – 100 g/t. The results of researches show that in the groups that received enzyme drugs in their diet, egg production was higher than in the control group. So, for the entire period of researches the hens of the experimental groups were significantly superior to the control group in terms of egg production per average laying hen. The largest difference was in hens of the 1st experimental group (enzyme drug Sunfyze) – 10,8 eggs; the smallest in hens of the 3rd group (enzyme drugs Sunfyze and Sunzyme) – 5,7 eggs. In hens of the 2nd experimental group compared with hens of the control group egg production was higher by 7,9 eggs. The best indicators of production efficiency have been obtained in the 1st experimental group of laying hens, which were fed with the enzyme feed additive Sunfyze to reduce the nutritional value of the diet according to the matrix.

The aim of the studies was to conduct a veterinary-hygienic assessment of changes in the eggs productivity of laying hens, after the use of the “Prinarovskaya supplement of fish (DKR)” in their main diet, which is a homogeneous dry mass made from chilled river fish, by-products of fish processings, as well as grain products (wheat bran). The method of production of the additive in-cludes the following steps: grinding, cavita-tion heating and subsequent drying of the resulting mixture. The studied supplement contains a number of amino acids, vitamins and minerals, etc. The object of the study were laying hens of the LomannLsn-Classic breed at the age of 131 days. “Prinarovskaya DKR” were introduced into the diet of ex-perimental laying hens: of the 1st experi-mental group 8 g of “Prinarovskaya DKR” were introduced per 100 g of the main ration (RR); The 2nd experimental group - 6 g. DKR to main ration; 3rd experimental group - 4 g. DKR to main ration; the control group was fed only main ration - feed PK1-1G_1227 (GOST: R 51851-2001). A veteri-nary-hygienic assessment of the quality of eggs, obtained from laying hens, when feed-ing a new feed additive “Prinarovskaya” was carried out. We kept daily records of laid eggs by groups, the period of the beginning of oviposition. The egg production were calculated of the initial and middle laying hens , the egg production intensity for 120 days. To assess egg productivity, the weight of laid eggs, the egg mass for a certain peri-od of egg laying, and the feed costs per 10 laid eggs were determined. Organoleptic, physical, and chemical methods were used to evaluate egg quality. Egg mass is an important indicator of egg nutrition. GOST 31654-2012 "Food eggs. Technical conditions ”, as well as the requirements for chicken hatching eggs, the minimum weight of food and hatching eggs (45 g) is indicated, below which the imple-mentation and incubation of eggs is not rec-ommended [1]. In studies, the following indicators were taken into account: large and small diameter of eggs, egg density, egg shape index of laying hens of different groups. To assess the state of the internal contents of the egg after opening, the follow-ing indicators were taken into account: pro-tein mass, yolk mass, shell mass, egg vol-ume. An external examination of the eggs as-sessed the condition of the shell, the pres-ence of cracks, growths and depressions. The study indicates a positive effect of the feed additive "Prinarovskaya" on the egg produc-tivity of birds in all periods of egg laying

For the experiment two groups of laying hens (control and experimental) have been formed with 70 heads in each. The diff erence between the groups was that the laying hens of the control group received a complete farm diet, and into the diet of the laying hens of the experimental group the feed additive “Availa Chrome 100” in the amount of 300 g/t of compound feed was introduced. It has been found during the study of the coeffi cients of digestibility of nutrients of the diet in the experimental poultry that the best digestibility diff ered laying hens of the experimental group where the additive “Avila Chrome 1000” in the amount of 300 g/t of compound feed has been put into the basic diet. It has been found as a result that the tested mineral additive increases the digestibility of dry matter by 3,09 %, organic matter by 2,59 %, crude protein by 1,35 %, crude fat by 2,16 %, crude fi ber by 0,63 %. The studied feed additive had a stimulating eff ect on the formation of red blood cells the level of which increased in the blood of poultry of the experimental group by 2,87 %. It has been found that in laying hens of the experimental group the level of hemoglobin was higher by 6,25 %. The use of the mineral complex allowed to improve the egg productivity of poultry by 3,3 % and increase the egg mass by 2,66 %. The inter-group economic eff ect for the period of experiment reached 573,43 rubles, so we believe that the use of organic chromium additives is economically feasible.

Highdem and for eggs requires a significant increase in production volumes subject to the standards of their quality. One of the components of the egg providing its safety and quality is the shell, which accounts for about 10-12% mass of the egg. The formation of eggs in chickens is a complex process, which is carried out within 24-27 hours, from which about 17-20 hours is given to form the shell. Since the main number of eggs chickens are demolished in the first half of the day, most of the calcification period of the egg shel falls on the dark period of day when the chicken stops to eat. A study was conducted to in vestigate the influence of an increased dose of calcium in the form of limestone particles when feeding it in the afternoon on the productivity and quality of chicken eggs. For this, two groups of laying-hens were formed, the mix feed for which consisted of the same components of cereal and protein-vitamin feeds, but was distingueished by calcium content, namely: in the control group in the mix feed, which was fed both in the morning and in the afternoon, was 3,5% calcium in the form of limestone thin and coarse grinding. The chickens of the experimental group in the morning were fed by mix feed with a calcium content of 1.5%, and in the afternoon - with a calcium content of 7% in the form of coarse limestone. Based on the research, it was found that during the 30-week period of productivity, the survival of chickens in the experimental groups was the same. Chickens of the experimental group reached 95% egg production at the age of 186 days, which his 5 days before the control group. Egg production on the middle and initial laying-hens in the experimental group for the whole production period was 178,4 eggs and 173,3 eggs, which is 6,2 and 7,0 eggs more than in the control group. The feeding of the chickens of the experimental group in the afternoon of mix feeds with an elevated calcium content contributed to an increase in the mass of eggs by 1,7 g, the exit of the egg mass on the middle and the initial laying-hens on 0,66 and 0,7 kg, the number of food eggs categories XL and L on 0,5 and 5.4%, compared with the control group of chickens, which was fed both in the morning and in the afternoon, a mix feed containing 3,5% calcium in the form of limestone thin and coarse grinding. Key words: laying-hens, mix feed, calcium, egg production, eggs mass, eggs quality.

This paper presents a study of the effect of the feed additive «Abiotonic» on the indicators of egg and meat productivity when applied to laying hens. It was found that with the additional introduction of this additive into the standard diet of poultry, the content of nonessential amino acids in their meat is 10% higher compared to the same parameters in the meat of chickens of the control group, the content of partially nonessential amino acids is by 8,5%, and of irreplaceable amino acids is by 6,7%. In addition, in the meat of laying hens, which used the feed additive «Abiotonic», the content of selenium (Se) is 29,4% higher than in the meat of birds of the control group, and iron (Fe) – by 20%. The average daily gain in live weight of the birds in the experimental group was 3,6 g more than in the control hens. Microbiological research made it possible to establish that poultry meat, regardless of the introduction of the feed additive «Abiotonik», meets the established requirements and is safe for human consumption. «Abiotonic», in addition, significantly improves the egg production of birds. It was found that the weight of eggs with the introduction of this feed additive in the diet in addition to the compound feed increased by an average of 1,2 g, and the egg production increased by 23 eggs in 7 days.

The physiological state of animals is to a certain extent characterized by hematological indicators, since blood occupies a special place in the body. By transferring nutrients and biologically active substances, the blood performs the general regulation of vital functions of the body. The use of Vitartil as a feed additive in the diets of animals leads to an increase in glycolytic processes and a decrease in the body’s need for oxygen delivery, which contributes to the growth of the animal body. The purpose of the research was to study the changes in blood parameters taking into account the age of Hereford steers against the background of the use of Vitartil feed additive to the main diet and its effect on the productive traits of animals. In order to carry out the experiment two groups of steers-analogs of Hereford breed have been formed at the age of 6 months per 10 heads in each. The difference between the groups was that the steers of the experimental group have been received the feed additive Vitartil in addition to the main diet. The greater yield of the meat part was in the steers of the experimental group in comparison with the herdmates of the control group. This indicator in the experimental group was 78,9 %, while in the control group it was lower by 1,6 %. The animals of the experimental group were superior to their herdmates in terms of meat weight by 1,4 kg or by 8,8 %. The relative number of bones was lower in the experimental group and amounted to 18,4 %, and in the control group 19,2 %. The meat content index was high in the steer have been received the biologically active additive Vitartil and was 4,3, and in the control group 4,0. It has been found that the use of Vitartil feed additive to the main diet of Hereford steers increases the blood content of hemoglobin and glucose, which has a certain effect on the morphological and chemical composition of meat, as well as increases its energy value.

The aim of this study was to evaluate the influence of the biopreparation Deodoric® on ammonia (NH3) concentration, performance, and hygiene standards in laying hen (ROSS-308) production. Statistically significant differences in NH3 concentration and the body weight of laying hens were observed between the control group (C) and the experimental group (E) where Deodoric® was applied at the set dose. In the control group, an increase in NH3 concentration could have contributed to the decrease in the body weight of laying hens, egg production, and % hen day egg production, whereas no such correlations were observed in the experimental group. A moderate linear correlation between NH3 concentration vs. humidity (r = 0.68), air flow (r = 0.48) and weakly linear correlation between NH3 concentration and age of birds (r = 0.27) was noted in group C. In group E, NH3 concentration vs. temperature (r = 0.27) and humidity (r = 0.14) were weakly correlated. Statistical analysis of changes in the microbial counts isolated from manure revealed a significant decrease of mesophilic microorganisms on day 28 decrease of Campylobacter spp. days 14 and 84 in group E. However, for the entire experimental model no statistically significant changes in the number of Campylobacter spp. and mesophilic bacteria were found. The tested preparation did not cause changes in the microbial composition of tissue swabs. Deodoric® contributes to animal welfare by reducing the ammonia concentrations in poultry houses. It is also recommended for use in poultry farms to improve animal health and performance and to generate benefits for producers.

Context Organic and herbal additives in feed may lead to more healthy animal products. For this study, we hypothesised that an organic form of selenium and/or a herbal additive (oregano, Origanum vulgare L.) may improve performance of laying hens. Aims The study was designed to determine the effects of selenium source (SS, sodium selenite; or selenium yeast, SY), oregano essential oil (OEO) and a combination of Se and OEO on performance, egg quality and blood parameters of laying hens. Methods In total, 216 Lohmann LSL-Lite laying hens, 66 weeks of age, were assigned to feed on one of six diets: control group, receiving basal diet (BD); BD + 0.3 mg SS/kg; BD + 0.3 mg SY/kg; BD + 250 mg OEO/kg; BD + 250 mg OEO + 0.3 mg SS/kg; BD + 250 mg OEO + 0.3 mg SY/kg. For each treatment, there were six replicates of six hens each for 12 weeks. Key results Feed conversion ratio was higher (P < 0.05) with the OEO diet than in the control. The SY diet decreased egg production and the OEO diet decreased egg mass (P < 0.05), although this effect was reversed with the SY + OEO diet. This would illustrate a synergistic effect of OEO with SY. Highest and lowest yolk colour values were found with the SY and SS diets, respectively (P < 0.05). Serum uric acid was lower with diets containing Se than the control diet (P < 0.05). Glutathione peroxidase activity was highest with SY and SY + OEO diets and lowest with the OEO diet (P < 0.05). Birds fed the SS + OEO diet showed the highest total antioxidant capacity and those fed SY showed the lowest total antioxidant capacity (P < 0.05). Conclusions Based on the results of the current study, it can be concluded that SY diet have increasing effect on egg weight in laying hens. In addition, novel synergistic effects between OEO and SY diets on improving egg production, egg mass and feed conversion ratio have been found. In terms of oxidative status, the detected synergistic effects between OEO and SS diets on total antioxidant capacity and between OEO and SY diets on glutathione peroxidase (GPx) have not been reported before, that appreciate more clarifying investigations in future. Although, dietary supplemental SY individually and also with OEO increased GPx, adding SS to diet together with OEO showed more improving effect on GPx compared to the separate usage. Implications Dietary supplemental SY can improve egg weight in laying hens. In addition, adding SY to diet of laying hens individually and with OEO have beneficial effects on oxidative status of bird in terms of GPs activity, which in turn can ameliorate the unfavourable impressions of probable environmentally oxidative stress on productive performance.

In this study, it was investigated the effect of clove oil supplementation at increasing levels into laying hens’ diets on performance, egg quality traits, some blood parameters and yolk TBARS (Thiobarbituric Acid Reagent) values. For this purpose 96 Lohman white laying hens, 28 weeks of age, were divided into four treatment groups. Control group was fed with basal diet (C) and treatment groups were fed with diets formed by addition of clove oil at 50 ppm (CO1), 100 ppm (CO2) and 150 ppm (CO3), respectively. During the trial, feed and water were given as ad-libitum, and poultry house was illuminated for 17 hours. Experiment lasted for 13 weeks. Addition clove oil at increasing rates into diet did not affect the live weight. The data analysed as polynomial showed that supplementation of clove oil into layer diet linearly improved feed conversion ratio and increased the egg production. But, daily feed consumption, egg weight, damaged egg ratio and egg quality parameters were not affected by treatments. Serum parameters such as triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase and calcium were not affected by the clove oil supplementation. TBARS values in C, CO1, and CO2 were found higher than the CO3 group fed with diet including 150 ppm clove oil. In conclusion, clove oil at 150 ppm level in diets of laying hens could be used due to extend the egg shelf life and to decline serum cholesterol content.
