The evaluation of the state of heterospecific resistance is conducted, stress stableness, reproductive ability and productivity of pigs of two breeds (large black, n = 30; large white breed. n = 19) in 2013-2016 in PAE "Dzvenache" Kyiv area. In the moment of researches common amount of sows of large white breed - 75, large black breed - 50 chairmen. The population of utricle of pigs of large white breed belonged to 2 lines, large black breed - 4 lines. In both breeds it is distinguished for 5 families. Reproductive ability of sows was estimated from data of опоросів, for the use of data of primary zootechnic account on a form 2-sw. Age of separation of piglets in an economy - 60 days. Haematological researches conducted after the generally accepted methods. Determined the amount of leucocytes of blood, phagocytal activity of leucocytes and intensity of phagocytosis. Blood was taken away for repair piggy-wiggies from an ear vein in age 8 months in the morning to feeding (experienced animals). In quality to the preservative used "Тrilon-B". For the evaluation of a stress status of animals used a eosinophilic test. In the experienced groups of animals studied the productivity and reproductive ability. From 30 animals of large black breed, haematological researches were conducted in which, a 21 chairman was used in a herd; 30 % animals were culled on different reasons. From 19 animals of large white breed, haematological researches were conducted in which, 12 chairmen were used in a herd. There was draft out 37 % animals, among what 68% with the mionectic indexes of heterospecific resistance (appraised as stress sensitive). As a result of complex evaluation of heterospecific resistance of pigs of large white and large black breed in PAE "Dzvenache"  is set: an amount of leucocytes the investigational animals of large white breed had within the limits of  7,5 - 16,4 thousands, and for the pigs of large black breed this index was within the limits of 8,2 - 15,6 thousand cages in 1 ml to blood, the amount of eosinophilic granulocytes for the animals of large white breed 1107,2±130 cell/ml presented  on the average., and for the animals of large black breed  - 610,7±85,7 cell/ml  an amount of red corpuscles, for the pigs of large white breed, was within the limits of 4,8 - 6,7 million cages, and for the pigs of large black breed 5,8 - 6,4 million cages in 1 ml of blood. Phagocytal activity (PhA) the investigated animals of large white breed had within the limits of 49 - 54%, and for the animals of large black breed within the limits of 40 - 62%, intensity of phagocytosis (IPh) for the animals of large white breed on the average presented 4,5 odes., and for the animals of large black breed 5,5 odes. Thus, on the indexes of heterospecific firmness of organism of pig of large black breed prevailed the persons of the same age of large white breed. A difference is highly reliable for PhA (Р<0,001),  IPh (Р<0,001), a reliable difference is also educed after the amount of eosinophilic granulocytes in 1 ml of blood (Р<0,01). After the eosinophilic test of 56% animals of large white breed were taken to stress stableness, and among the investigated pigs of large black breed, stress stableness animals it was on 12% anymore (Р<0,01). The polycarpousness of sows of large white breed was on the average 10,6±0,14 piglets on опорос, and in the sows of large black breed - 9,5±0,40 piglets on опорос, however,  for the sows of large white breed, on 1.8% anymore it was stillborn piglets, that comports with literary data about the high reproduced ability of pigs of large black breed. Among the animals of large white breed it is educed 44% of stress sensitive individuals. From data of analysis of variance force of influence of a stress status on mortinatality presented 38%. (η2х= 0,38; Р< 0,05). Stored of young animals in a suction period the sows of large black breed had higher on 1,8 % than for the sows of large white breed. It we explained by that the animals of large black breed are more proof to stress and have higher indexes of heterospecific resistance. This fact is confirmed by previous researches . After the index of living mass the new-born piglets of large white breed (1,72±0,23) prevailed the persons of the same age of large black breed (1,43±0,31 (Р<0,001)). In age 60 days the substantial is set, statistically reliable, difference after living mass between the piglets of two breeds, so the piglets of large white breed (18,2±0,33) prevailed the persons of the same age of large black breed (16,8 ±0,23) on 1,4 kg (Р<0,001). The educed economic-biological features of pigs of two breeds in the conditions of one economy specify on perspective of large black breed in relation to stored to the sapling/pl and diminishing to departure of piglets in an early period of ontogenesis. At the same time a large white breed prevails after polycarpousness. Thus, in the conditions of economy of PAE "Dzvenache" it is expedient to conduct the interbreed crossing with the purpose of fixing of valuable internalss of educed in breeds and providing of sufficient level of profitability.

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.

Purpose: the goal is to study in the piglets of a large white breed of influence of body weight at birth (large-way) on the thickness of the scraping and the age of achieving the live weight of 100 kg.Materials and methods. The object of the study - piglets (hrying and pigs) of a large white breed from birth until they achieve a live mass of 100 kg. The growth and development of piglets-sausage was studied by weighing them at birth. Primary data included 4215 weight records at the birth of tribal purebred piglets of a large white breed (hrying and pigs). Posyat, both live births and stillborn, weighed individually within 24 hours from the moment of birth. Weighing was carried out on scales with an accuracy of 100 g. The conditions of detention and feeding were the same. Three groups of experimental animals were formed, taking into account the live masses at birth. The first group was made up piglets with low live weight (1.0 kg and lower), the second - piglets with a normal body weight at birth (from 1.1 to 1.9 kg) and were divided into nine subgroups of 0.1 kg, the third - individuals with high live weight (2.0 kg and above). The thickness of the strika was measured in a lifestyle-meater ultrasonic device in the region over 6-7 breast vertebrae when a live mass of 100 kg is achieved (in the range of 60 kg to 150 kg).Results. It has been established that the floor of the animal, multipleness, month-year of birth, herd, liveborn or stillborn piglets in litter affect the average weight of the birth of piglets, as well as the thickness of the scraping and the number of days to achieve a live weight of 100 kg. The difference in weight at birth between the floors was insignificant, and the males were somewhat heavier piglets. Piglets 3 groups have had a higher average weight at birth compared to piglets 1 and 2 groups. Bible weight decreased when the size of the litter increased with 4 piglets (n = 54) to 17 piglets (n = 22). Piglets with a low live weight at birth had the most thick thickness of the striking at a weight of 100 kg and the longest was taken to 100 kg. In animals with high body weight at birth was the thinnest thickness of the strik, and it took the least day to reach the live weight of 100 kg. The thickness of the strip that pigs with a living weight of 100 kg decreased with an increase in body weight at birth. In pigs with a low live weight at birth, the strik thickness was 0,5 mm thicker (p≥0,999) compared with pigs weighing 1.4 kg and 1.5 mm thick stuck (p≥0,999) compared with the 3rd group. A significant correlation -0,20 was found between the live body weight at birth and the thickness of the scraping when the animals reach 100 kg.Conclusion. Thus, the sex of the animal, multipleness, liveborn or stillborn piglets in the litter - all this affected the middle weight at the birth of piglets, as well as the thickness of the scraping and the number of days to achieve live weight 100 kg. Analyzing the above data, we can assume that the ratio rate (weight of the birth of piglets) must be considered to further predict the productivity of the animal.

The research was carried out on the basis of the farm of LLC "Russia" Mozhginsky district of the Udmurt Republic. The object of research was sows of the main herd of Large White breed in the amount of 100 heads. The age of the sows was 24 months under two farrows in the year. The aim of the research was evaluation of the  reproductive qualities of the sows of the main herd in the context of families, by calculating a complex indicator of the reproductive qualities. The index evaluation of the reproductive qualities was carried out to take into account such indicators as: the prolificacy, the milkness, the number of piglets in 2 months and the masse of the nest in 2 months. The obtained experimental data were processed in a tabular redactor program Microsoft Excel - 2010. The evaluation of the reproductive ability of the sows in the main herd in the context of families showed that the sows of the families Beatrisa, Ovatsia and the Volshebnitsa differed from the sows of the families Skazka, Soya and the Palitra more higher prolificacy- by 0.36-1.44 heads, a mass of the nest in 2 months - by 2, 58-22.46 kg and the number of piglets in 2 months - by 0.35-0.78 heads. The complex indicator of the reproductive qualities of the sows of the families Beatrisa, Ovatsia and the Volshebnitsa, exceeded the complex indicator of the reproductive qualities of the families Skazka, Soya and the Palitra by 3.52-12.82 points.  The evaluation of the reproductive qualities of the sows of the families Beatrisa, Ovatsia and the Volshebnitsa showed that they exceeded the average level on the herd on the prolificacy- by 3.04 heads, the mass of the nest under weaning piglets in 2 months of age - by 9.03-28.72 kg, the number of the piglets under weaning in 2 months of age - by 0.62-1.64 heads, and on the complex indicator of reproductive qualities - by 8.90-19.39 points. The results of the research made it possible to select the best sows for the breeding stock and use them widely in the reproduction of the herd.

Leptin receptor is one of the components of the system of regulating energy homeostasis of the organism. Leptin receptor gene (LEPR) polymorphism is associated with pig carcass index of the content of intramus- cular fat in its valuable parts, which is particularly important when assessing the quality of their carcasses for processing. Intramuscular fat is associated with meat fl avor characteristics and partly determines its tenderness, juiciness, and other parameters. Aim. To analyze LEPR gene (SNP NM001024587.1, p. 1987 C > T) polymor- phism in populations of various pig breeds and to establish its relationship with the quality of both meat and fat of pigs of Large White breed of Ukrainian breeding. Methods. Genetic-population analysis of nine pig breeds, associative analysis on the search connection of LEPR gene polymorphism with quality of both meat and fat of pigs of Large White breed of Ukrainian breeding. LEPR locus genotyping was performed by High Resolution Melting (HRM). Results. All the studied breeds are characterized by polymorphism of the leptin receptor gene (SNP NM001024587.1, p. 1987 C > T), signifi cant breed specifi city in the distribution of frequencies of alleles was established. Statistically confi rmed effect (p < 0.05) of genotypes LEPR on the content of intramuscular fat, total dry matter and moisture in the meat, as well as the moisture content in the back fat of pigs of Ukrainian Large White breed was revealed. Higher content of intramuscular fat was found in the animals with genotype TT, while a smaller amount of intramuscular fat and more moisture in fat was revealed in heterozygotes. Conclusions. Genetic marker LEPR SNP NM001024587.1, p. 1987 C > T can be used in the marker-assisted selection to predict and improve the performance quality of the meat of pigs of Large White breed of the Ukrainian breeding. These results suggest that porcine leptin receptor gene controls the quality of fat comp- lex – inside muscles and in the dorsal part of the carcass.

Studies were carried out on the main indicators of the chemical composition and physical properties of muskulus longissimus dorsi of pigs of different genotypes during hybridization. The indicators of the chemical composition and physical properties of muskulus longissimus dorsi were determined by conventional methods. The materials of experimental studies were processed using methods of variation statistics. According to the amount of moisture, no significant difference between the control and experimental groups was established. According to the amount of protein in meat, a tendency to a slight decrease, compared with the control group by 1.4 (group III) … 1.9 % (group II) was established. The use of boars of Poltava meat breed led to a decrease in intramuscular fat in descendants by 0.25 % compared with peers of a large white breed (P <0.95), and precocious meat - to a real increase of this indicator by 0.43 % at P> 0 , 95. A tendency towards an increase in the amount of tryptophan (by 0.04 ... 0.05) and oxyproline (by 0.004 ... 0.005) in the muscles of hybrid animals was revealed in comparison with peers of pure breed of large white breed. In terms of the biological usefulness of meat proteins, animals of group III were the best - in terms of the quality of the protein of the longest muscle of the back, their advantage over peers of group II was 0.07, and compared with purebred peers. Group I - 0.12 (p <0.95). It was found that with the same area of the meat spot both in purebred large white breeds of animals and hydrides of different genotypes, there is a tendency to increase the latter compared to the control in a humid place: with a «share» of «blood» ½ pm by 2.2 %, and with a «share» of blood ½ cm - 1.4 %. A tendency has been established to increase the pH value of the longest back muscle in animals with a «share» of blood of specialized meat breeds compared with a large white breed. In hybrid animals with a «share» of blood of Poltava meat and precocious meat breeds, there is a tendency to increase the pH value in comparison with the large white breed by 0.15 (2.8 %) and by 0.17 (3.1 %), i.e. the meat of hybrid pigs, the pH of which has a shift towards alkalinity due to less accumulation of lactic acid, has a worse preservation.

Improving of fertility indicators and reproductive qualities of sows during artificial insemination in farms of different specializations is very topical issue. The introduction of artificial insemination of sows on breeding farms by the spermdoses of optimum volume, by the frozen-thawed and sex sperm requires the introduction of innovative reproductive technologies. The use of economical methods of artificial insemination of sows using a minimum number of sperm in a small volume of spermdose in order to achieve high rates of fertility and prolificacy was proven in numerous experiments of the authors. Significantly reduced spermdose may be sufficient if the sperm enters deep enough into the uterus. Vitality of sperm does not depend on the size of spermdose, but the best place for sperm to survive one oviducts where they keep the fertilizing capacity from 9 to 27 hours. So deep intrauterine insemination of sows improves conditions for sperm survival The aim was to study the feasibility and justification for widespread implementation in to production on breeding farms of intrauterine insemination of sows morder to increase their fertilization and prolificacy and  to save the boar sperm with the highest index of breeding values. Experiments were conducted in terms of selection and genetic center of Agrofirm "Mig-Service-Agro" in Mykolaiv region. In the experiment used 65 sows of live weight of 280-320 kg wiht 2-4 farrowing were. Sows in sexual hunting were showed once daily in the morning using a boar-prober. Artificial insemination was performed twice: the first time - in the afternoon and at 14-16 p.m. The second time – in the morning of the next day at 9-10 am. For artificial insemination of sows were ed using experimental spermodes with volume of 40 ml which contained 1.5 billion of a Active sperm. For the dilution of sperm was used Durasperm - KRUUSE (Denmark) the period of sperm perpetuation is 5-7 days. To enter the were semen used catheters Magaplus S, (Spain) for intrauterine insemination of sows. Analysis shows that the period from weaning to insemination has significant difference comparing sows of large White breed with Landrace breed (p <0.001), with genotype sows F1 (p <0.01) and sows of the Duroc breed (p <0.05). For all selected 65 sows duration of suckling period, was estimated which averaged 32.2 days and the average time from weaning of pigs to their sexual inclination and the first intrauterine insemination 6.8 days that meets the physiological norm. After intrauterine insemination of sows of then 48 farrowed, which wich made for 73.9%. іncluding live 5 emergency farrow  were obtained, representing 10.4% of all amount. Percentage of farrow is considered physiologically normal – 80%, or more of total insemined sows. The very low percentage of farrow 53.3% had of sows F1, and the highest percentage was found by sows of the Duroc breed – 85.7%. Pregnency of sows were received just 17, which made 26.1% and highest percentage – 46.7% was set by sows F1. Analysis of the pregnancy sows shows that on average it is 116.2 days was the longest – 117.1 days was set in Landrace breed sows and the short est 115.5 days in Large White breed, but the difference is not significant. 571 pigs were received, іncluding live 451 head, which is 78.9%. The largest percentage of іncluding live piglets obtained from sows F1 – 82.5%, and the lowest in Landrace breeds – 77.0% and Large White – 77.3%. Exit of all piglets per sow without emergency farrowings is 12.2, іncluding live – 9,8. The highest yield were obtained piglets from sows F1 – 13.1, іncluding live – 10.9, the lowest yield of sows of the Duroc breed – 10.6, іncluding live 9.1, which has significant difference compared with the control (IDPs) and other breeds.  After intrauterine insemination 8 sows showed cyclic deregulation in 20-25 days, ie repeated sexual hunt took place on average 22.3 days. These sows were inseminated by not fractional way, they farrowed and an average litter just 13.1 piglets per sow, іncluding live - 11.3 was obtained. Repeating after intrauterine insemination on 45-48-49 day in the sexual hunt came about three sows for artificial insemination by not fractional method 3 farrowed and was obtained output – 13.3 piglets, іncluding live – 11.7. It should be noted that the best sow Large White breed №12 after intrauterine insemination bore 16 pigs, іncluding live 11, sow of Landrace breed №1556 – 18 pigs, іncluding live 12, Duroc №5888 – 13 pigs, іncluding live 11, sow F1 №167 – 20 pigs, іncluding live 14 pigs. Breeding requires more careful handling with major sows taking into account their breeding value and cost, that’s why we believe that there is no need to risk causing injury genitals with intrauterine insemination if a sufficient number of spermdoses of boars-sires exist.
