The Cost

Breeders of edible eggs, using various crosses of chickens, try to reduce the cost of production. In this regard, interests of hen crosses that produce egg products with low feed costs and low cost. One of these egg crosses of hens is “Lohmann brown light”. At the same time, domestic poultry farms successfully use the “Lohmann Braun classic”cross poultry. The aim of the study was to evaluate the egg productivity indicators of laying hens of the industrial herd of crosses “Lohmann brown classic”and” Lohmann brown light”. The study was carried out in the conditions of LLC Poultry Farm “Varaksino” of the Udmurt Republic. For the research, 2 groups of hens were formed, consisting of 6 batches each. As a result, hens of the studied crosses were characterized by approximately the same viability and level of livestock preservation – 94.1 – 94.3 %. Crosses of hens “Lohmann brown classic” and “Lohmann brown light” had minor differences in quantitative and qualitative indicators of egg production. Thus, egg production for the initial and average laying hens in the groups was at the level of 348.2 – 350.5 and 353 – 355.2 eggs, respectively. The amount of egg mass from the cross “Lohmann brown classic” hens was 22.9 kg, and from the cross “Lohmann brown light” - 22.6 kg. On an equal background of feeding, there were no differences in the cost of feed for the production of 10 eggs (1.29 – 1.31 kg) and 1 kg of egg mass (2.03 – 2.05 kg) in the studied hen crosses.

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.

This experiment studied the effect of DPP supplementation in the laying hens’ diet on the ovarian follicle development, hematological variables and hormonal profile of laying hens. Eighty-four, 78-week-old, Lohman LSL hybrids layers were equally divided into four groups (4 groups × 7 replicates × 3 hens); hens in the 1st group were fed a basal diet (control), while those in the 2nd, 3rd and 4th groups, were fed on the same diet and supplemented with 1.25, 2.5 and 5.0 g DPP/kg diet. The results showed that the egg weight, egg mass and laying rate of laying hens treated with DPP levels were significantly increased compared to those of the hens in the control group. Egg weight, egg surface area, albumen quality and percentage of the yolk in treated hens significantly increased compared with controls. The increased DPP levels in laying hens‘ diet significantly (p < 0.05) increased WBC, Hb and TAC, while heterophil/lymphocyte (H/L ratio) significantly decreased. Additionally, the concentrations of FSH and LH and the weights of ovary and oviduct in the treated hens significantly (p < 0.05) increased compared with the control. In conclusion, the DPP supplementation in the hen diet significantly improved egg production, EW, H/L ratio, ovarian follicles, FSH and LH hormones concentrations.

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).

A 16 week feeding trial was conducted with 140 White Leghorn layers of 22-23±0.08 weeks of age which were distributed randomly into seven experimental groups, having 4 replicates with 5 birds in each. The laying hens of control group (T1) were fed a basal diet (CP 18.04%), while in treatment groups T2, T3, T4 basal diet was supplemented with probiotic (containing 5×108 cfu/g of Lactobacillus fermentum, 1×109 cfu/g of Bacillus spp., 1×109cfu/g of Saccharomyces cerevisiae) at levels of 0.5g, 1.0 g and 2.0 g /kg feed, respectively, while in T5, T6, and T7 0.5g, 1.0g and 2.0g/kg feed of prebiotic (mannonoligosacchride of Saccharomyces cell wall-47g, formic acid-32g) was supplemented, respectively. The percent hen day egg production and feed efficiency (kg/dozen eggs and kg/kg egg mass) were improved (P less than 0.05) in probiotic and prebiotic incorporated diets. The mRNA expression levels of Toll like receptors (TLRs) TLR2 and TLR4 was increased (P less than 0.05) when graded levels of the probiotic and prebiotic were supplemented, while, TLR7 did not show any significant change. Thus, it can be inferred that the inclusion of the probiotic and prebiotic could enhance the production performance and immune status of birds by augmenting the T cell mediated immune response.

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 quality of the received products directly depends on the state of the microflora of the gastroin-testinal tract that is reflected, in particular, on the egg productivity of laying hens. As a result, the use of biologically safe preparations, namely, probiotics, is becoming a priority in the poultry industry. This work aims to establish the feasibility and effectiveness of the use of the complex probiotic products Immunoflor in the diet of laying chickens of the Dekalb White Cross. Based on the comprehensive research, the feasibility of using the complex probiotic product Immunoflor in egg production technology to improve the egg-laying capacity and the quality of the obtained eggs of laying hens of the Dekalb White cross was scientifically substantiated and experimentally proven. Against the background of the use of this drug, it was found that the average daily egg-laying capacity in the 1st and 2nd experimental groups exceeded the control layers: on the 150th day - by 9.66% and 8.48%, on the 180th day - 8.8% and 5.04%, on the 210th day - 8.16% and 6.44%, on the 240th day –11.68% and 3.8%, 270th day – 7.72% and 4.84%, on the 300th day – 8.34% and 5.86%. Besides, the average daily egg mass in the 1 and 2 experimental groups was higher than in the control by 4.04 g and 3.1 g or 7.38% and 5.77%; on the 7th day of storage, the average value exceeded by 4.06 g and 3.1 g or 7.53% and 5.87%; on the 14th day - by 4.32 g and 3.16 g, or 8.18% and 6.12%, respectively. It was found that on the 7th day of storage, the mass loss in the 1st and 2nd experimental groups was 1.50% and 1.56%, which is lower than in the control (1.66%). On the 14th day of storage, the mass loss in the 1st and 2nd experimental groups was 1.95% and 2.36%, which is also lower than in the control (2.63%). With the use of the probiotic preparation, the loss in egg mass decreases. On the 7th day of storage, the mass loss in the 1st and 2nd experimental groups was 1.50% and 1.56%, which is lower than in the control group (1.66%). On the 14th day of storage, the mass loss in the 1st and 2nd experimental groups was 1.95% and 2.36%, which is also lower than in the control (2.63%).

In recent years, interest in the use of peat as a feed supplement has increased, particularly due to its capacity to prevent enteric diseases and to stimulate growth in animals and poultries. Peat is an easily available natural material and a source of biologically active substances widely used, not only in agriculture but in human and animal medicine as well. Biological activity of various peat preparations is associated not only with fluctuations in the chemical compositions, but also with different application techniques. experiment was carried out on two groups of poultry under the conditions of a poultry farm in the Republic of Moldova. Its purpose was to determine the use of a feed supplement - peat concentrate as a new unconventional feed ingredient in the composition of mixed feed for laying hens and its influence on their egg production, average weight and category of eggs. The objectives of the study included the study of the chemical composition of the peat supplement and the determination of the effect of peat powder additive on the egg production. The effect of the dosage of the peat preparation in the amount of 1% (experimental group) was studied and the obtained results were compared with the control group, in which the laying hens consumed the basic compound feed. The high concentration of active ingredients and the uniqueness of the components of the peat feed supplement, the adsorbing properties due to the presence of humic acids and lignin in its composition, made it possible to increase the natural immune response in laying hens by increasing the egg production of laying hens by 7.2%; by improving the quality of products such as the average egg weight by 4.72%; egg mass by 12.6%; the height of the egg white by 23.96%; the width of the egg white by 2.14%; and an increase in colour intensity by 0.43 units, while reducing the cost of food.

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.
