The Impact

The results of determining the validity and strength of the impact of paratypical (number and season of farrowing, year of birth) and genotypic (sow family) factors on the characteristics of sows’ reproductive qualities in the conditions of the breeding reproducer EE "DG im. 9 Sichnia”. As a result of determining the reliability of the influence of these factors by one-way ANOVA it has been found out that the year of birth and the ordinal number of farrowing significantly influence on the indicators of the number of piglets at birth, the number of piglets and the weight of the litter at weaning. At the same time, the average weight of one piglet during weaning was recorded by the significant influence of only genetic factors (sows family), and the influence of paratypical factors was not reliable, which indicates the possibility of effective selection by phenotype in improving this trait. The results of the analysis of variance also showed that under the conditions of EE “DG im. 9 Sichnia”no significant influence of the“ farrowing season ”factor was found on any of the studied traits of reproduced ability. The results obtained were used in the construction of linear BLUP models for the determination of breeding value on the grounds of reproductive qualities in the conditions of EE "DG im. 9 Sichnia”. Maximum indexes of the characteristics of reproductive ability recorded in the 2-3rd farrows, starting from the 4th farrow, all indexes begin to decline, especially this is noticeable for the trait "weight of the litter". In sows of 2017 year of birth, compared to 2015, there is a slightly smaller number of piglets and the weight of the litter at weaning (by 4.5-6.7 %), while the average weight of one weaned pig increased by 0.2 kg. This fact is explained first of all by rejecting sows - among the sows that were born earlier (in 2015), as a result of the breeding work, less productive sows were rejected, and only those with high parameters remained. The linear models which have been developed with scientifically-based parameters will be used at the next stage of the work in determining the breeding value of pigs in the EE “DG im. 9 Sichnia“. Key words: breeding, reproductive qualities, factor, impact force, sows family, linear model.

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.

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.

The objective of the paper was to evaluate the results of reproductive performance of sows in some elite breeding herds of the Large White breed included in experimental herds for the production of hyperprolific lines of dam breeds. The set consisted of 98 sows with the known genotypes of ESR, FSH&acirc; and PRLR genes. The dendrogram shows that on the basis of their genetic outfit the sows can be divided into two clusters. The first cluster can be described as a cluster with marked dominance of HPL sows and the second cluster with marked dominance of the sows of basic herd. The first cluster consisted of individuals in which the preferred genotype AA of PRLR gene was not detected. As for FSH&acirc; gene, the beneficial genotype BB was found out in 74.10% of sows. In ESR gene the beneficial genotype DD was recorded only in 11.10% of individuals. On average for the lifetime performance they delivered by 2.08 piglets more in all born piglets and by 1.96 piglets more in live-born piglets per litter. Differences in the reproductive traits between HPL sows and the sows of basic herd in the first cluster were statistically highly significant. On the contrary, genotype AA of PRLR gene was identified in all sows of the second cluster, 61.36% of animals possessed beneficial genotype BB of FSH&acirc; gene. As for ESR gene, beneficial genotype DD was identified within the whole cluster in 31.82% of sows. In lifetime performance the HPL sows had on average by 1.10 individuals more in all born piglets and by 1.01 more in live-born piglets (statistically significantly higher values). The unambiguous expression of a positive effect of preferred genotypes of selected candidate genes failed to be confirmed by the results of statistical analyses testing the associations of candidate genes for pig reproduction with selected parameters of breeding value and prolificacy of sows. &nbsp;

Goal. To accelerate the selection process and create populations of pigs with high level of productivity to assess the most effective modern methods breeding value of large white pigs in the SE "DG" Pasichna "Institute of Feed and Agriculture Podillya NAAS" Starosinyavsky district of Khmelnytsky region on the basis of a combined assessment of repair young for their own productivity and assessment meat qualities by MD Berezovsky and B. Tyler and the most promising method BLUP. Methods. Comparison, zootechnical and biometric analyzes. Results. The breeding value of pigs of large white breed of the breeding farm of SE "Pasichna" ICSGP NAAS "Starosinyavsky district of Khmelnytsky region by modern effective methods, namely: BLUP. According to the average indicators of the combined assessment of own productivity of animals at control fattening, taking into account their live weight on the date of birth and weaning, average daily gain, live weight and age of 100 kg, body length and fat thickness, boars significantly outweighed pigs. Compared with pigs, their live weight at the date of birth and weaning (at the age of 30 days) was higher by 0.1 and 0.81 kg. The age of reaching a live weight of 100 kg exceeded by 5.43 days, the average daily gain of 0.016 kg. Live weight and body length of pigs on the date of fat thickness measurement was greater by 4.04 kg and 1.03 cm. Lifetime fat thickness at three measurement points at the level of 6–7 thoracic vertebrae, on the buttocks and in the midpoint of the back between withers and buttocks was thinner by 0.92; 0.94 and 1.06 mm. Evaluation indices of fattening and meat qualities by growth energy and fat thickness (Ia) and average daily gain and fat thickness (Iv) in boars indicate their higher level by 2.07 and 7.67 points compared to pigs and are equal to, respectively, 95.12 ± 1.95 and 152.96 ± 2.38 points. The coefficient of variability (Cv, %) of indicators of own productivity and estimated indices of fattening and meat qualities of repair boars ranged from 1.92% (body length on the date of fat thickness measurement, cm) to 15.12% (age of live weight 100 kg, days), repair pigs – from 4.63% (body length on the date of fat thickness measurement, cm) to 28.19% (index of assessment for growth energy and fat thickness, (Ia), points). The best average values of indicators of breeding value of animals are found on the basis of modern, most promising method BLUP, because it is considered in terms of mathematics, statistics and selection is the most accurate, well-founded, has the best theoretical basis and the lowest error variance. The average value of the BLUP index (parent lines) for boars of large white breed is 101.71 ± 1.681, pigs – 96.94 ± 0.724 points. At the same time, boars outweighed pigs by 4.77 points. The most positive correlation between live weight of piglets at weaning with their body length (r = 0.16), average daily gain (r = 0.19) and fat thickness (r = 0.24), the average correlation between the indices of fattening and meat qualities according to MD Berezovsky and B. Tyler (r = 0.56) P > 0.99 and the weak correlation between live weight of piglets at weaning and the BLUR index (r = 0,21) P > 0.99. It should be noted that there are almost no correlations between the fattening and meat quality indices of pigs and the BLUP index. Conclusions. In the conditions of breeding and specialized farms for the production of commercial pork in the region, to determine the breeding value of animals for further reproduction of their own herd and sale to other breeding farms of Ukraine, to systematically assess repair young animals for their own productivity and clear qualities of pigs and the most perfect BLUP index.

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.

This study examines certain identifiable non-genetic sources of variation (parity number, year and season farrowing) for their effects on Large White sow litter performance traits, such as litter size, mortality and weight of piglets at birth and at weaning. The population used for the present study is from a pig farm managed by Tavriys’ki svyni, LLC, located in Skadovsky district (Kherson Oblast, Ukraine). Reproductive performance records on 280 Large White (LW) sows were used. A total of 633 litters were farrowed from January 2007 to July 2017. The litter records included information on the total number of piglets born (TNB), number of piglets born alive (NBA), number of stillborn piglets (NSB), frequency of stillborn piglets (FSB), average weight of piglets at birth (AWPB), litter size at weaning (NW), piglet pre-weaning mortality (PWM) and average weight of piglets at weaning (AWPW). To determine the effect of parity number, year and month farrowing on reproductive performance traits, the analysis of variance (ANOVA) was used. Results obtained showed significant influence of parity number on most of the reproductive parameters studied, apart from AWPB, PWM and AWPW. The total litter size at birth was the lowest in primiparous sows and in cases second-parity sows, but significantly exceeded the overall average population estimation during the fourth-sixth parities farrowing. The least squares estimates of the mortality rate of piglets at birth were significantly lower than in second parity sows, however they significantly increased in sows at eighth parity. The year of the sow's farrowing had the most significant influence on the weight of piglets at birth and at weaning. Moreover, a clear upward trend can be noted in relation to the weight of piglets at birth, which is accompanied by a gradual increase of the corresponding least squares estimates during 2007-2015. Late summer and early autumn (August-October) are the seasons when the litter size traits in the LW sows consistently show the lowest values, indicating a ‘seasonal infertility period’. Thus, all the analysis performed in the present work shows that in the LW sows, as in other pig breeds, the parity number, year and season farrowing influence the reproductive and developmental processes.

The speciality of the modern methodology in breeding is using the molecular information, received during genome analysis. This methodology can significantly accelerate the improvement of productivity traits and it is particularly useful in relation to the traits with low coefficient of inheritance while classic methods are not effective enough. The reproductive traits are one of the most important in pig farming, estrogen receptor 1 gene (ESR1) is involved in their control. Meanwhile, the use of ESR1 locus polymorphism in the marker-assisted selection needs to determine the extent of its association with the reproductive traits of animals in those populations where it is planned to conduct such selection. Implementation of marker-assisted selection in Large White and Mirgorod breeds for improving the reproductive traits is an actual task, but a necessary step in this work is the associative analysis. The purpose of the work is to research the association of polymorphisms of ESR1 locus with some reproductive traits of sows of Large White breed (ULW-1 and ULW-3 lines) and sows of Mirgorod breed. Materials and methods of research. Experimental groups: 1) the sows of Large White breed, ULW-3 line, bred in "Bahmutskiy Agrarian Union" farm, Donetsk region; 2) the sows of Large White breed, ULW-1 line, bred in “Stepne” farm, Poltava region; 3) the sows of Mirgorod breed, bred in «Named after Dekabristy» farm, Poltava region. All the experimental animals were previously genotyped on RYR1 gene and had RYR1CC genotype. The animals were genotyped on estrogen receptor 1 locus with aid of PCR-RFLP analysis on PvuII-polymorphic restriction site in the third intron of the gene – DNA marker for estrogen receptor 1 gene. Associations between genotypes and the studied traits were calculated using ANOVA in Excel 2007. Results. ULW-3 sows with ESR1BB genotype turned out to have 1.36 more piglets in a litter (analysing data from 2nd-4th farrows) comparing to animals with ESR1AA genotype. There is a tendency for bigger amount of newborn piglets in the heterozygotes animals than in sows with homozygous ESR1AA. A similar pattern appears in the 1st farrowing, the sows with ESR1BB and ESR1AB genotypes had the advantage in the total number of piglets at birth. In the experimental group of ULW-1 sows statistically proven patterns were not found, there was only a tendency to slight predominance of sows with ESR1BB and ESR1AB genotypes comparing to individuals with ESR1AA genotype. In the experimental group of Mirgorod sows there was a tendency to have most part of individuals with heterozygous genotype. Analysis of prolificacy of ULW-3 sows due to their genotype for the estrogen receptor 1 gene confirmed the superiority of ESR1BB and ESR1AB genotypes comparing to ESR1AA sows. According to 2nd-4th farrows, sows with ESR1BB and ESR1AB genotypes had the advantage in prolificacy comparing to ESR1AA sows by 1.15 and 0.53 piglets, respectively. According to the 1st farrowing difference between genotypes was absent. ESR1/PvuII-polymorphism do es not influence on prolificacy of ULW-1 sows. According to the 1st farrowing the trend towards a higher level of prolificacy of Mirgorod sows with ESR1AA genotype was found, while difference in 2nd-4th farrows between the groups was absent. It was found that ESR1/PvuII-polymorphism impact on the total number of piglets at birth and prolificacy for ULW-3 sows is characterized by predominance of additive component with a little contribution of the dominant component, the similar trend is observed for ULW-1 sows. There is a complex nature of the impact of ESR1/PvuII-polymorphism on the reproductive traits of Mirgorod sows in the predominance of the dominant component. Conclusions. The impact of polymorphism in estrogen receptor 1 gene on the total number of piglets in the litter after the birth and prolificacy in ULW-3 sows was detected. ULW-3 sows with ESR1BB genotype have 1.36 more piglets in a litter (analysing data from 2nd-4th farrows) and 1.15 more comparing to animals with ESR1AA genotype. ESR1/PvuII-polymorphism was not associated with total number of piglets in a litter and prolificacy in ULW-1 sows and Mirgorod sows. The counted parameters of additive-dominant model indicate that ESR1/PvuII polymorphism impact on the total number of piglets at birth and prolificacy for ULW-3 sows is characterized by predominance of additive component with a little contribution of the dominant component.

Alanine Aminotransferase Activity

The article presents the results of studying the influence of cortical and vegetative mechanisms of regulation on the transaminase enzymes activity in blood serum of dry sows under exposure to a technological stimulus. The experiments were carried out on sows of large white breed of 3 years old. The results of research have shown that the indicators of conditioned reflex activity affect the activity of reamination enzymes in blood serum both under physiological conditions and after the exposure to a technological stimulus. According to the correlation analysis, the relationship between the strength and balance of cortical processes with serum alanine aminotransferase activity (r = 0.48–0.65; Р≤0.05–0.01), as well as the strength of cortical processes with aspartate aminotransferase activity (r = 0.51; P≤0.05). The significant influence (η2x = 0.23–0.36; Р≤0.01) of the balance of cortical processes on the activity of alanine aminotransferase in blood serum was established. Instead, the tone of the autonomic nervous system had a significant influence on the activity of reamination enzymes only after the exposure to a technological stimulus. In particular, the significant degree of influence (η2x = 0.28; P≤0.05) of sympathicotonia on the activity of alanine aminotransferase in blood serum on the 7th day after exposure to a technological stimulus was established.

Goal. To assess the reproductive ability of inspected sows of different families of large white and Poltava meat breeds in breeding herds of Khmelnytsky region on the main selection signs using the evaluation indices of reproductive qualities. Methods. Comparison, zootechnical and biometric analyzes. Results. The reproductive qualities of sows of different families in breeding herds of pigs of large white and Poltava meat breeds of farms of Khmelnytsky region were evaluated. Among the families of large white breed, the best indicators for assessing the reproductive capacity of inspected sows were found in the family of the Sorceress, in which the main feature – fertility by modal class of distribution was 10.8 heads piglets per 1 farrowing, which is 2.8% more than the Taiga family of the same class. According to the modal class M+, the fertility of the Sorceress family (12.0 piglets per farrowing) was 0.3 heads higher than that of the females of this class of the Taiga family (11.7 heads per farrowing). The modal class М¯ of the firstborn family of the Sorceress was the best with a fertility of 9.7 heads, which is 3.2% higher than the Taiga family. Indicators of the number of piglets at weaning at the age of 30 days, the weight of the nest at weaning, the live weight of 1 head of piglets and preservation of offspring (9.5 heads; 94.1 kg; 9.9 kg; 87.9%), by class (М°), the Sorceress family was 3.2 heads bigger; 7.4 kg; 2.0 kg and 0.5% compared to the Taiga family. As a result of ranking sows by evaluation indices of reproductive qualities, I (evaluation index by a limited number of traits) and P (complex evaluation index) had an advantage by the most prolific sows of the Sorceress family of class M+, in which these indices were 43.0 and 96.1 points. In the process of research of reproductive ability of sows of Poltava meat breed of different families it was established that on the basis of fertility the Rosinka family is the best, whose fertility by distribution by class (М°) was 10.7 heads. piglets per 1 farrowing. It exceeds the average value for 5 families: 0.4 heads of Dorza and Vorskla families, 0.6 goals. Bystro's family and 1 goal. the Palm family. According to the modal class M+, the Rosinka family (11.8 piglets per 1 farrowing) has 0.3 heads more fertility than the Dorza and Vorskla families, 0.6 goals higher. and 0.1 heads than the Bistra and Palma families. The lowest fertility of sows in the class (М°) was recorded in the Dorza family (8.9 heads of piglets per farrowing). It should be noted that the Dorza family and the smallest Palma family in the M+ class have the best nest weight at weaning at the age of 45 days (138.7 and 144.2 kg), which is 18.6 more than in the М° class. and 20.7 kg. According to the indicators of the number of piglets at weaning and live weight of 1 head, the Palma's family of class M+ (10.6 heads and 13.6 kg) is distinguished. The best preservation of the offspring in the Palma's family of class M¯ = 94.7%. As a result of ranking sows of different families of Poltava meat breed according to the estimated indices of reproductive qualities, it was noted that the highest number of points in the modal class (М°) was obtained by the family Rosinka I = 40.8 and P = 94.8, which is more than the average for all families by 2.1 and 3.6 points. According to the evaluation indices (I) and (P), the best were sows of the Rosinka family of class M+, in which these indices corresponded to the values of 42.7 and 99.4 points. Conclusions. Among different families, the best results of assessing the reproductive capacity of sows on the main selection traits and evaluation indices were found in the families of the Sorceress of the Great White breed and the family of Rosinka of the Poltava meat breed, which should continue to be used for breeding in breeding herds of pigs. An important factor in increasing the productivity of sows, of course, should be the correct selection of the level of reproductive breeding traits and a significant increase in feeding and housing conditions.
