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).

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.

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.

Trace Element Deficiency

The Altai Region along with the regions of the Siberian Federal District belongs to the zone with trace element deficiency including iodine deficiency. The research goal was to study the effect of iodine on edible egg quality of laying hens of the Rodonit cross. At the final stage of egg-laying, 4 groups of 4 laying hens were formed. No iodine was administered to the hens of the 1st control group. Starch-based iodine product was administered to the birds of the 2nd, 3rd and 4th trial groups into the lower third of the neck, under the wing and into the rump area in a dose of 1.5 mg per head. The egg production intensity in the trial groups was higher by 21.3-28.8%. Egg weight in the 1st control group was 65.6 ± 1.33g which was lower than that in the trial groups by 4.4% (2nd group); 3.7% (3rd group) and 1.5% 4th group). All eggs belonged to “select” grade. The 3rd and 4th trial groups had less egg white by 3.8 and 2.7%; the egg-yolk content increases in the eggs of the 2nd, 3rd and 4th trial groups by 1.2%, 9.4% and 2.4%, respectively, and the eggshell weight by 1.2-9.4% as com-pared to the control. The ratio of egg white and egg-yolk weight in the eggs of the trial groups was lower than in the control group by 9.38-19.29%, but the ratio of egg-yolk to egg white was by 10.4-23.9% higher. The following indices were higher in the trial groups as compared to the control: egg white index -by 1.4-17.1%; egg-yolk -by 3.2-6.4%; Haugh unit -by 7.2-11.1%; eggshell thickness -by 3.9-8.3%. The best results were obtained with the administra-tion of iodine to the hens in the region of the lower third of the neck. The enrichment of the body of laying hens of the Rodonit cross with iodine makes it possible to obtain the profitability of edible egg production at the level of 28.6-41.0%.

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

In this study, 160 73-week-old laying hens (HyLine W-36) were used to investigate the changes in production performance and egg quality parameters of aged laying hens after injection of different doses of growth hormone (GH) and a fixed dose of testosterone (Ts). The hens were weighed individually, placed in laying cages and then randomly assigned to four treatments with four replicates of 10 birds each, in a completely randomised design. The experiment was started at the 75th week and lasted until the 82nd week of age. The treatments were: 1: injection of 100 µL distilled water (control group), 2: injection of 500 µg Ts/kg liveweight + 50 µg GH/kg liveweight, 3: injection of 500 µg Ts/kg liveweight + 100 µg GH/kg liveweight and 4: injection of 500 µg Ts/kg liveweight + 150 µg GH/kg liveweight. In this study, ovulation rate (egg production percent), egg mass and feed intake were significantly higher in Treatment 3 than the control group (P < 0.05), and in Treatment 4, feed conversion ratio was significantly higher than for the other experimental groups (P < 0.05). In addition, the birds in Treatment 3 showed greater egg weight, albumen height, eggshell weight, eggshell density and eggshell weight per surface area than the control group (P < 0.05). In Treatment 3, egg length significantly increased compared with Treatments 1 and 4 (P < 0.05), and in Treatments 2 and 4, shell breaking strength was significantly lower than for the control group (P < 0.05). In conclusion, our results showed positive effects of GH and Ts administration on egg quality parameters and production performance in aged laying hens. Taken together, in the present study Treatment 3 was found more effective in improving egg quality and production performance of the old laying hens.

Aim. Study of the effectiveness of the use of the feed additive "Mega HenOn" in the training of chickens of an industrial herd of the cross "Highsex brown" under heat stress. Materials and Methods. Evaluation of the efficiency was carried out for 32 weeks on industrial chickens in the amount of 70 heads. During the experiment, the egg production of chickens (daily), feed costs, and the category of eggs were taken into account. To determine the quality characteristics of edible eggs, GOST 31654-2012 “Edible hen eggs. Technical conditions". Results. The studied additive had a positive effect on the egg productivity of chickens, both during heat stress and during normalization of the temperature regime. At the age of 47-50 weeks (June-July, the ambient temperature during the daytime increased to 38-40°C), egg production dropped sharply, and in the control group it was 79.03%, and in the experimental group, despite the decrease, it exceeded this indicator by 3.63%. At the age of 51-58 weeks (July-August, the increase increased to 36°C), the decrease in egg production continued, but in comparison with the previous period, there was a certain trend towards recovery, which amounted to 85.51%, exceeding the control by 2.22%. The studied feed additive, to some extent, neutralized the negative effect of heat stress on the body of birds. In general, over the period of the experiment, the egg-laying intensity in the experimental group was 89.1%, and in the control group - 87.09%. The cost of producing 10 eggs in the experimental group is 1.29 kg, which is 0.07 kg less than in the control group. The yield of eggs of the category "superior" and "selected" in the experimental group exceeded the control by 0.53 and 16.89%. The yield of eggs of the II category turned out to be higher in the control group and amounted to 29.56%, which is higher than in the experimental group by 13.73%. Conclusion. The use of the innovative “Mega HenOn” feed additive, in the diets of chickens during the heat stress period, contributed to a more complete realization of the genetic potential of birds, due to the stabilization of metabolic processes in the body of birds, an increase in egg production, a decrease in the yield of culling eggs and, as a consequence, an increase in the level of profitability by 2.38%.

Abstract In the era of increased antibiotic resistance and ever stricter control on antibiotic use, it is urgent to develop green, safe and non-residue alternatives to antibiotics applied to the poultry industry. To this end, we supplied the potential Lactobacillus Plantarum (L. Plantarum) fermented Astragalus in the diet of laying hens, with a final addition of 3‰. Its effects have been assessed on laying performance, egg quality, antioxidant and immunological status and intestinal microbiota, and are compared to the control group, to the Astragalus group containing 3‰ unfermented Astragalus, and to the L. Plantarum group containing 2% L. Plantarum (1 × 108 CFU/mL). During the second half of the experimental period (15 to 28 days), the egg production rate was significantly higher in the fermented Astragalus group than that in the other groups, with the fermented Astragalus group having the lowest feed conversion ratio. No significant difference (P > 0.05) was observed among treatments on egg quality. Fermented Astragalus-treated hens exhibited significantly increased catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in serum, and reduced malondialdehyde (MDA) in serum. Furthermore, fermented Astragalus supplementation resulted in a significant increase in ileal microbiota abundance relative to control. In conclusion, feeding laying hens with L. Plantarum fermented Astragalus has beneficial effects on production, antioxidant potential, immunity and ileal microbiota. L. Plantarum fermented Astragalus is expected to be a novel feed additive used in poultry production.

The purpose of the research was to study the eff ect of the mineral complex “Availa Chrome 1000”, which used in the feeding of laying hens of the highly productive cross Highsex Brown under the conditions of the Research Center for the Safety and Eff ectiveness of Feed and Additives of the Volgograd State Agrarian University. 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.

The research objective is to establish Hyplus meat breed of young rabbits and to determine growth and development characteristics during the period from weaning to slaughter age under conditions of the biologically active feed additive of humic nature «Humilid» introducted into their general diet. The control and experimental groups of animals were formed according to the principle of similar groups. Experiment study lasted for 35 days, including 7 days preparatory period, 21 days research period and 7 days aftereffect period. The young rabbits of the control and experimental groups were fed with the main diet, which included compound feed with an individual calculation of nutrients per animal. The young rabbits of the experimental group were additionally injected with a biologically active feed additive «Humilid» in the form of an aqueous solution in an amount of 5 mg/kg of body weight according to the active substance to the main diet for 21 days. During the experiment, the effect of «Humilid» on the growth and development of young rabbits and their physiological state was studied. The weighing of young rabbits in the experimental groups was carried out once a week. At the same time, their body weight was determined on average and average daily growth, the safety of the livestock, in addition, the weight and mass index of the liver, heart and kidneys after slaughter by the calculation method. With the introduction of the feed additive «Humilid» to young rabbits, an increase in the body weight of the animals is observed throughout the experiment. The body weight on average of young animals of the experimental group exceeded this indicator in comparison with animals in the control group by 17.2 % (p˂0.001). Under the conditions of the introduction of the biologically active feed additive «Humilid» over the period of the experiment, the average daily weight gain of young rabbits in the experimental group was higher by 20.7 % (p˂0.01) compared to this indicator in the animals of the control group, respectively. The safety of the livestock was 100% in both groups. However, it should be noted that young rabbits of the control group had more pronounced motor activity and signs of anxiety than the animals of the experimental group, which obtained the feed additive of humic nature «Humilid». When «Humilid» was used in the diet, the mass of organs and the index of their development in young rabbits in the experimental and control groups of animals were within the range of age-related changes, which indicates the non-toxic effect of this additive.
