And Storage

The influence of breed and storage period of hatching eggs on the duration and results of incubation and the development of quail was studied. It has been noted that in breeding quail farms, the collection period for hatching eggs can be as long as 2-3 weeks. Storage time has a negative effect on incubation time, embryo development, egg hatchability and hatchability of young chicks, which consequently reduces the economic efficiency of the poultry farm. The study was carried out on the eggs of the Pharaoh and Texas White quail breeds. It was found that storage of quail eggs for more than 7 days reduces the hatchability of eggs by 8.3-38.2% and the hatchability of young quail eggs by 15.7-41.4%. Reduced fertilization of eggs correlated with the loss of egg weight during storage (r = 0.974-0.995, p < 0.05). Extending the shelf life of quail eggs to 14-21 days increased the average incubation hour of the Pharaoh breed by 6.3-12.1 hours, and the Texas white breed by 2.5-9.7 hours, had a significant effect during the embryogenesis period on the live weight of day-old quails of both breeds, utilization of yolk sac nutrients and development of the heart, liver and gizzard (η2 = 0.541-0.902, p <0.05-0.01). Hatchery eggs of the meat quail breeds Pharaoh and Texan White should be stored for no more than 7 days before incubation. The results of this study can be used in breeding, industrial and farm quail farms for planning sampling times, the number of eggs laid for incubation and places for planting day-old chicks, the number of future layers, the amount of feed needed; in the educational process of agrarian educational institutions.

Harmful Effects

During the storage period, changes in morphological and biochemical parameters occur in the egg. The composition of the microflora on the surface of the egg shell changes, while their hatchery traits decrease. The rate of “aging” of eggs depends on the quality of the shell, protein and yolk, on the shelf life, the level of contamination of the shell surface with microorganisms, temperature, humidity, gas composition of the environment, the position of the eggs in space, and so on. Many methods of preserving the quality of the hatchery egg and the viability of the embryo in it have been studied. However, not all storage techniques are suitable for each species of birds. So, the method of storage with a sharp pole up in a sealed package is optimal for eggs of meat chickens, and in turkeys, when stored in the sealed package, the hatchery traits are sharply reduced. At the same time, the storage of turkey hatching eggs with a sharp pole up allows to increase their hatchability by 0,78–1,63 % (a week of storage) or to neutralize the harmful effects of biochemical changes in the egg and to keep the hatchability of eggs at the level of 85,20 and 80,10 % (two and three weeks of storage). The use of sealed packaging for storing turkey hatching eggs without sufficient airing time leads to a decrease in the results of brooding, and with the increase in the shelf life, the negative effect increases and the hatchability of eggs decreases from 89,53–91,22 % (one week of storage) to 27,08–46,86 % (three weeks of storage). In any case, the shelf life of two and three weeks negatively affects the quality of daily poults, which is expressed in an increase in live weight by 0,05–0,90 and 0,30–1,21 %, as well as the decrease in the length of daily poults by 2,44–3,11 and 3,08–3,37 %, respectively.

This study investigated the effects of pre-storage heating and storage period of hatching eggs on hatchability traits and chick quality of Dokki-4 (Egyptian local strain of chickens) laying hens. A total of 3600 eggs were collected from 46-week-old laying hens. Eggs were distributed in a 3x4 factorial arrangement, with three storage times (4, 8 and 12 days at 18°C and 75% RH) and four heat treatments prior to storage (0, 3, 6 and 9 hours at 37.5°C and 56% RH). Eggs were distributed to twelve treatments of 20 replicates. After storage, eggs were incubated under the normal conditions of incubation at the same time. The results showed that the long storage period increased egg weight loss. Hatchability and chick quality results from 8-12 days stored eggs were lower than eggs stored for 4 days. The 6-hour pre-storage heating system substantially improved egg hatchability and chick quality relative to non-heated or 9-hour heating. Important interactions were observed during pre-storage heating × egg storage time for loss in egg weight, hatchability of total and fertile eggs, embryonic mortality and chick quality. When eggs were stored for more than four days, pre-storage heating of hatching eggs for six hours improved hatchability and chick quality compared to unheated eggs or heated for 9 hours. Conclusively, pre-storage heat treatment beneficially affects hatchability traits and chick quality, especially when hatching eggs are stored for long periods.

Hatching Eggs

The treatment of hatching eggs plays an important role in ensuring the epizootic well-being of the poultry enterprise. For disinfection of hatching eggs, chemicals that have a negative effect on the developing embryo, service personnel and the environment are widely used. In this regard, the search for effective antimicrobial agents is an urgent area of veterinary medicine science and practice. An alternative to chemical preparations can be antibacterial agents of plant origin. The purpose of the research was to study the effectiveness of a plant-based drug based on pectin for the treatment of quails’ hatching eggs. The research has been carried out in the department of veterinary medicine of agricultural poultry in Siberian Scientific and Research Institute of Poultry – a branch of the Federal State Budget Scientific Institution “Omsk Agrarian Scientifi c Center”on hatching eggs of quails of Pharaoh breed. In order to treat the hatching eggs of quails of the experimental group, a 1 % solution of the drug based on pectin was used before setting and on 15,5 days of incubation when transferring from the incubation cabinet to the hatchery. In the control group the eggs have been treated with formaldehyde vapors according to the generally accepted method. It has been found as the result of the conducted studies that the drug based on pectin in comparison with formaldehyde reduces the total microbial contamination of the shell by 58,7–73,8 %, the species diversity and the intensity of the release of the microflora of the shell by 20,0–40,0 %. Reducing the microbial background has the positive influence on the embryonic and postnatal development of quails, increasing the hatchability of eggs by 2,5 %, the output of young quails by 2,9 %, stimulating metabolism, increasing the live weight of quails by 3,3–4,1 % and livability by 2,0 % over the period of 1–14 days of life. The proposed method is harmless and environmentally friendly.

The application of constructive geometric modeling to pedagogical models of teaching graphic disciplines today is a promising direction for using computer technology in the educational process of educational institutions. The essence of the method of constructive geometric modeling is to represent any operation performed on geometric objects in the form of a transformation, as a result of which some constructive connection is established, and the transformation itself can be considered as a result of the action of an abstract cybernetic device. Constructive geometric modeling is a popular information tool for information processing in various applied areas, however, this tool cannot be appreciated without the presence of appropriate software systems and developed design techniques. Traditionally, constructive geometric modeling is used in the design of mechanical engineering, energy, aircraft and shipbuilding facilities, in architectural and design engineering. The need to study descriptive geometry at the university in recent years has something in common with the issues of mastering graphic packages of computer programs in the framework of the new discipline "Engineering and Computer Graphics". The well-known KOMPAS software product is considered the simplest and most attractive for training. It should be noted the important role of graphic packages in the teaching of geometric disciplines that require a figurative perception of the material by students. Against the background of a reduction in classroom hours, computer graphics packages are practically the only productive teaching methodology, successfully replacing traditional tools - chalk and blackboard.

Aim. Based on the results of multi-year research into the flax gene pool, to form a flax training collection to provide breeding scientific organizations and educational institutions with collection samples as well as with information about the bast crop gene pool. Results and Discussion. The studies were conducted in the crop rotation fields for breeding and seed production of the Institute of Bast Crops of the NAAS (Hlukhiv, Sumska Oblast) in 1992-2018. The field measurements and laboratory analyses were carried out in accordance with conventional methods of field and laboratory studies of collection flax samples.The article presents the results on the formation of a training collection of flax at the Institute of Bast Crops of the NAAS, which has 117 accessions (11 botanical species and three varieties) from 22 countries. In addition to species diversity, the collection includes accessions with different levels of expression of valuable economic and biological characteristics. It also includes accessions selected by phenotypic variability of individual characters or their combinations. The multi-year research into the flax collection accessions resulted in identification of sources of highly-expressed valuable economic traits, which are of interest for the plant breeding course. The history of flax breeding in Ukraine is shown, where breeding varieties that are most widespread or were significant breeding achievements in solving certain problems, are presented. The collection can be used as a visual aid for the plant breeding course in educational programs; in addition, it can provide starting material for scientific and educational institutions. The collection is registered with the National Center for Plant Genetic Resources of Ukraine (certificate No. 00273 dated 04/11/2019). Conclusions. The studies of accessions from the national flax collection allowed us to build up a training collection and register it with the NCPGRU. The collection represents a wide range of biological and economic features of the gene pool of this crop. The collection can be used in the educational process of educational agricultural and biological institutions. The multi-year research into the national flax collection resulted in identification of sources of highly-expressed valuable economic traits, which are of interest to the plant breeding course. The history of flax breeding in Ukraine got covered, and breeding varieties that are most widespread or were significant breeding achievements in solving certain problems are presented.

The results of studies of the reproductive ability of sows of different genotypes are given taking into account the polymorphism g.1426G> A of the MC4R gene, the factor of repeatability of characters is determined, and the economic efficiency of the research results is calculated. The experimental part of the research was carried out in the conditions of the «Druzhba-Kaznacheevka» LTD in Dnipropetrovsk region. The objects of research were sows of the Large White breed. It was determined that sows of the main herd, according to signs of reproductive ability, belong to class I and class elite. The experiment showed that sows of genotype AG exceeded their peers of others (GG and AA) in terms of “born piglets total, heads” by 1.6 and 0.7 heads, “Live piglets born (multiple births), heads - by 1 6 and 0.9 heads, “the mass of the litter at the time of birth, kg” - by 2.7 - 1.3 kg., “the mass of the litter at the time of weaning at the age of 28-35 days, kg” - by 5, 1 - 3.9 kg. The difference between animals of the indicated genotypes is: for large-foetus - 0.06-0.01 kg, the index "evenness of the sow’s litter in live weight of piglets at birth, points" - 1.05-1.84 points, index of N. D. Berezovsky - 3.75 -2.36 points. The index of the safety of piglets before weaning ranged from 84.4 to 93.0 %. It was proved that the minimum value of the index “evenness of the sow’s littar in live weight of piglets at the time of birth, points (7.76 ± 1,082 points) are characterized by sows of genotype AA, in which the rate of multiple pregnancy ranged from 8 to 14 pigs, and the value of the sign“ large-foetus, kg "equaled 1.37 kg. The repeatability coefficient for sows of the main herd and sows of the Large White breed of different genotypes for the melanocortin 4 (MC4R) receptor gene ranges from -0.916 ± 0.1418 (І-IV farrow, genotype - GG, sign - “piglet safety before weaning, %) to 0.978 ± 0.0738 (I-V farrow, genotype - GG, sign - “large foetus”, kg ”). The maximum value of the phenotypic consolidation coefficient was found in sows of genotype AA according to the following quantitative characteristics: “live piglets (multiple births), heads.”, “litter weight at the time of birth, kg”, “litter weight at weaning age of 28-35 days, kg "," the safety of piglets before weaning ,% ". The sows of the genotype GG belong to the unconsolidated group according to the signs of reproductive qualities. The use of sows of the genotype for the melanocortin 4 (MC4R) AG receptor gene provides additional products at the level of 5.15 %, and its cost is 165.41 UAH /head. Keywords: sow, breed, reproductive ability, MC4R gene, genotypic consolidation coefficient, variability, correlation, repeatability.

Contemporary Reality

The crisis of values is pervasive resulting in adverse development in all walks of life. Misra, Srivastava and Gupta (1995) have found that present emphasis on personal growth as opposed to societal development, non-commital attitude, inconsistency in behaviour across situations, increase in violence, corruption, indiscipline and social tension have become parts of the contemporary reality experienced in everyday life of people. There is a progressive erosion of values resulting in public life. Educational institutions are no exception. A proper value system must be inculcated by educational institutions through educational process based on rationality, scientific and moral approach to life. It would be possible to serve the need of the hour through proper value orientation among teacher education programmes.
