Abstract The aim of the study was to study the effect of the feed additive “Verva” on the reproductive ability of sows and the recovery of their sexual cyclicity. Fir triterpenic acids are the main active ingredient of the feed additive. The study was conducted on 80 sows of the large white breed. Experimental and control groups were formed: GE (n=50), GC (n=30). GE sows from the 80th day of pregnancy for 30 days were additionally given “Verva” at a dose of 3 g per head per day. GC sows weren’t given the “Verva”. Hunting was detected within seven days after weaning the piglets. Artificial insemination was performed twice and the effectiveness was determined on day 28 by ultrasound. The number, weight of newborn piglets in GE and GC don’t differ significantly. By weaning, 10.94±0.17 heads were obtained from one sow in GE, which is 9.1% (p < 0.01) more than in GC. By weaning, the weight of the nest (total weight of piglets) in GC was 66.72=2.13 kg, which is 7.3% (p < 0.05) less than in GE. The “Verva” has a positive effect on the activation of sexual cyclicity: in GE, 95.3% of animals came to the hunt, and in GC-by 4.4% less. On the 4th day after weaning the piglets, 34.1% of the animals came to the hunt in GE, 40% in GC, on the 5th day–46.3% in GE and 50% in GC. On the 6th, 7th days in GE, 17.1% and 2.1% of sows came to the hunt, and in GC, 10.0% and 0.0%, respectively. The efficiency of artificial insemination in GE was 95.4%, which is 13.5% higher than in GC. The “Verva” has a positive effect on the milk production of sows, preserves their progeny, sexual cyclicity after weaning piglets, increases the duration of economic use of animals.

Weaning Piglets

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.

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.

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;

The results of tests of a new combined feed additive Bioprotektin-KD based on milk thistle extract with the addition of a complex of bacteria of the genus Lactobacillus and Bifidobacterium to restore intestinal microbiota of animals are presented. Preclinical studies on the effectiveness of the feed additive were conducted on mice with experimental antibiotic-associated dysbacteriosis. Studies on the intestinal microbiota of mice revealed varying degrees of effect of different doses of feed additive on the recovery of resident microflora. The results of pre-clinical studies have proven the harmlessness, non-toxicity and efficacy of the feed additive. Clinical trials of the additive were carried out on productive animals. Its effect on the productivity of black-motley breed cows in a livestock farm in the Belgorod region was studied. The use of the functional feed additive Bioprotectin-KD had a positive effect on the milk productivity of black-motley breed cows. Cows in the experimental groups that received the feed additive had increased their milk yield per lactation by 209.41-499.01 kg compared to the control animals, which was 4.01-8.78%. The quality indicators of milk have increased. The composition of the microflora of the experimental (feed supplement recipients) and control calves was studied. It was found that the quantitative composition of probiotic flora in the intestines of young calves of the control group remained practically unchanged throughout the experiment. The number of indigeneous microflora (lactobacilli and bifidobacteria) increased in the experimental animals. The content of lactic acid microorganisms in the experimental calves began to increase on day 6 of feed supplementation and reached physiological norm on day 30. The safety index of the product has been calculated. The use of the functional feed additive Bioprotektin-KD in conditions of a livestock complex has improved such production indicators as calf survival, average daily weight gain, and milk productivity of cows in the experimental groups of animals as compared to the control ones.

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.

In these studies, it was found that seasons have a significant impact on the reproductive function of Large White boars. It was found that these indicators were the highest in winter, and the lowest in summer. Studies have also shown that the inclusion in the diet of Large White boars of the feed additive “HydroLaktiV” in a dosage of 1.0, 1.5, 2.0% over the main diet allowed to increase both quantitative and qualitative indicators of sperm. An increase in the quantitative and qualitative sperm indicators of the studied boars in turn led to an increase in the number of piglets in these groups by 7.4, 11.6, 11.4%, respectively; a decrease in their cost at birth by 7.0, 10.4, and 10.3% compared to the control group.

The results of morpho-biochemical, immunological studies and data on the antioxidant status of young laying hens of Czech Dominant breed when including “Profort” feed additive in the ration are presented. The study was carried out in the conditions of the poultry farm of Krasnoye Podvorie farm in Belgorod region. The chickens were divided into two groups: experimental and control. Young birds of the control group received the main ration. As for the experimental group, “Profort” feed additive, which contained Bacilius megaterium B-4801 and Enterococus faecium l-35, was used at a dose of 0.5 kg / t in combination with the main ration. Blood samples for research were taken on 11, 21 and 42 days. In the course of the studies, a positive effect on morpho-biochemical, immunological parametres and parametres of antioxidant defense system of egg cross chicken blood when using “Profort” probiotic was revealed. A decrease of the content of monocytes, eosinophils, lymphocytes and pseudo-eosinophils was noted throughout the entire period of the study in blood of young birds of the experimental group, compared to the control group. The concentration of alpha-globulins in the blood of birds of the experimental group was higher throughout the entire period of the study relative to the parametres of the control group. The maximum difference in immunological parameters of the blood of birds of the experimental and control groups was achieved on the 42nd day of the study. So, lysozyme activity of blood serum of young laying hens of the experimental group was higher by 18.8%, and the content of CIC and general Ig - by 30.7% and 21.9%, respectively. A decrease of medium molecular peptide level in blood shows a positive effect on the antioxidant status of the organism
