In recent years, there has been a problem of low reproductive capacity of cows in the farms of Rivne region. A retrospective analysis conducted by us in the region showed that 57.0% of dairy farms in the region have to be re-inseminated over several sexual cycles. In this case, 53.0% of cows are fertilized after 150–180 days after calving and give 3500–4000 kg of milk per year. The enterprises have a prolonged service period, which is 130–140 days. There is a shortage of calves, namely their output per 100 cows is 65,0–70,0. In addition, farms keep a large number of cows with poor feed conversion efficiency. An example is the situation in the farms of LLC SGP “them. Volovikova” of Goschansky District, FG “Mriya”, SE “Belokrynitske” of Rivne District, PSP “Ukraine” of Dubrovytskyi District, where 8765 cows that were bred from November to February 2016-18 were subjected to obstetric dispensation, namely: the service period was 148–154 days, and the yield of calves per 100 cows was 70.0–76.0. At the diagnostic stage of obstetric examination, the spread of obstetric pathology in cows during periods of dryness, calving and post-calving was analyzed. In the period of dryness, there were cases of subsidence to childbirth 5.2% (1.7–17.0%), udder edema 4.6% (2.4–13.8%, and subclinical mastitis 6.8%. Metabolic disorders include diseases such as ketosis 3.5% (0.8–12.0%) and fatty liver syndrome 5.7% (5.0–7.0) In the cows of FG “Mriya” the level of ketone bodies was at the level of 2.0 ± 0.04 mmol/l. In the course of the farm surveys, the pathological course of childbirth was recorded in 1431 cases, representing 16.3% of the total number of surveyed and 25.9% of feral animals. In addition, 534 cows (6.1%) experienced mechanical damage and trauma to the vulva and vagina mucosa. 426 cows (4.9%) noted further development of postpartum vulvо-vaginitis and erosion of the genital organs. In 1777 cows (20.2%) cases of postpartum paresis were recorded, of which the largest share was 27.8% in FG “Mriya”. In the cows of the farms studied, the most common form of mastitis was subclinical, which was found in 3.1% – 42.0% of cows. The clinical form accounted for 38.0% of diagnoses. In FG “Mriya” of the Rivne region, the subclinical form of mastitis was recorded most in cows post-otelny period – up to 40.0%, whereas in dry period – 11.0% of cases. PSP “Ukraine” practically did not diagnose the clinical form of mastitis. Prospective in the study of the etiology of metabolic and obstetric diseases will be the study of individual indicators of quality and safety of feed, clinical and laboratory studies of pathology of the reproductive system, which will become the basis for early diagnosis of these diseases.

There is a problem in the farms of the Khmelnytsky region of reducing the reproductive capacity of cows. Our analysis in the region showed that in the studied cows of the Native Land Branch of PJSC “Grain Products MHP” and PE “Demetra-2010” the length of the service period and the postpartum period are somewhat longer. The service period during all three lactations was smaller in cows of the Branch “Native land” of PJSC “Grain product MHP” by 11.9 days for animals of PE “Demetra-2010”, the average period indicator was 169.3 ± 65.04 and 181.2 ± 31.11 days, respectively. In a retrospective analysis which was conducted by us in the leading farms of the Khmelnytsky region, it was found that the share of obstetric diseases in the structure of non-communicable cow pathology was 21.9 % in the Branch “Native Territory” of PJSC “Zernoproduct MHP” and 22.5 % in PE “Demetra 2010”. At the diagnostic stage of obstetric examination, the spread of obstetric pathology in cows during periods of dryness, calving and post-calving was analyzed. In the period of dryness, there were 8.1 % (7.5–9.9 %) cases of sedimentation, 3.9 % (2.3–4.5 %) udder edema. In the course of the farm surveys, the pathological course of childbirth was recorded in 3360 animals, accounting for 54 % of the total number of surveyed and 88.5 % of feral animals. Namely, in 1417 cows (22.8 %) observed pathology of the third stage of childbirth (delay of litter), in 963 cows (15.5 %) observed weakness of the generic activity. In 723 cows (11.6 %), birth trauma was reported. Postpartum complications in the cows surveyed in the Khmelnytsky region were observed postpartum sepsis (0.3 %), infected wounds after caesarean section (0.2 %) and vulva (0.1 %) postpartum vulva-vaginitis (7.1 %), subinvolution uterus (11.2 %) and endometritis (21.6 %). It was found that cows of the dry period were diagnosed with subclinical mastitis, which fluctuated within 13.3 %, respectively. Whereas clinical mastitis in the dry season on average on farms sick 7.4 % of animals. Prospective in the study of the etiology of metabolic and obstetric diseases will be the study of individual indicators of quality and safety of feed, clinical and laboratory studies of pathology of the reproductive system, which will become the basis for early diagnosis of these diseases.

Effect Of Feeding

Scientific and production experiments were carried out on cows of Ukrainian Black-and-White diary breed (UBAWD) of SE "Seagull" (branch "Lisne") during 2016–2017. The anatomical and physiological state of genital organs of cows was determined by the method of clinical and gynecological research of animals before conducting experiments and during them every 40–50 days. In total 486 cows were kept under control, which were kept in typical rooms with running platforms, but the active motivation of animals was clearly insufficient. Feeding cows according to the recommended standards. The milk yield from the cow in 2017 was 7813 kg. The experiments studied the effect of feeding cows during the dry period, the conditions of retention and some other paratypic factors on the course of the genera and the postnatal period, the duration of the service period and the fertility of cows. In analyzing the research results, personal records and veterinary documentation were used. In conducting experiments, it was found that normal calving was in 89% of cows, and severe and pathological – in 11% of cases. The main diseases in the afterlife period were: detention of the litter – 9.5%, postpartum endometritis – 21.5%, hypofunction of the ovaries – 23.0%, persistent yellow ovarian bodies – 25.6% and others. Normal intervals between stages of excitation of the sexual cycle (18–22 days) were in 63% of cows, and violations of the rhythm of sexual cycle, associated with dysfunction of the ovaries and missed the hunt – 30% of animals. Subunvulation of the genital organs of the cows contributed to the diseases of the limbs, udder and digestive disorders. During 2016–2017, the effect of feeding cows (173 g.) in the dry period on the course of calving, post-autumn period and their fertility was studied. Under the same conditions, keeping cows in the maternity ward and feeding rough and succulent feeds concentrated feeds fed cows of the control group (98 heads) to 1–2 kg daily during the dry period, and experimental (75 heads) – for 18–20 days to calving 2–3 kg. A positive difference was found in favor of cows of the experimental group: there was a more active stage of expulsion of the fetus, less delay of the placenta (by 7%) and endometritis (by 12%), the duration of the postoperative regenerative period decreased by 8.6 days; service period – 19.0 days; fertility from two inseminans was higher by 5.7%. Study of the reproductive capacity of cows at the hotel in different seasons showed that the recovery period was shorter by 11 days in the presence of cows in 3–4 quarters, and the service period – by 23.2 days at hotel in I and IV sq. The average duration of the recovery period was 79.5 days, while the service period was 123.4 days. The longest duration of the joint ventricle was in cows at hotel during the hot summer days of the year. The average fertilization rate from the first insemination of 339 cows was 44.9% with fluctuations in individual groups of milkers from 26.8% to 55.0%. The following indicators were in the number 1 and number 3 (respectively 26.8% and 31.4%). The best fertility rates were in groups № 4, 6 and 7, where there were more cows of the second and third lactation, and the responsible attitude of the milkers to work in organizing cows walks and sexually explicit hunting. When comparing the assessment of the duration of the IP and SP in full-age cows and cows, the first-born, taking into account 225 goals. It was found that these indicators were longer in primitive cows – 20.7 days respectively and 21.9 days in relation to full-age cows. The obtained results are completely consistent with the results obtained by a number of both domestic and foreign researchers. More attention is needed to grow heifers and to prepare newborns for delivery. In 15–17% of cows at and after the hotel, gynecological diseases that occurred in the presence of gastrointestinal diseases, lameness, mastitis and others were diagnosed. This has negatively affected the overall performance of the herd. In studying the duration of HP and SP in healthy and sick cows after calving, it was found that if the SP in healthy cows lasts 73.4 days, then in patients – 116.3 days (the difference was 42.9 days), and the difference in the duration of the joint venture reached 98.7 days. On the basis of the results of the research, it can be concluded that the reproductive function of the cows is influenced by such paratypic factors as feeding animals in the dry period, the temperature factor (time of year), the human factor (the effect of milking on a group of cows), age and physiological state of cows in the hotel and in the afterlife period. When feeding 2–3 kg of bovine feed for cows, together with rough and juicy fodder for 18–20 days prior to calving, the recovery period decreased by 8.6 days and service period – by 19 days, and fertility from two inseminals increased by 5.7%, reaching 85.3%. The smallest duration of the service-period was in the presence of cows in the I and IV quarters year (107.7–117.1 days). In primary cows, the recovery period was longer than that of full-age cows by 20.7 days, and the service period was 21.9 days. In the physiologically healthy cows after calving, the recovery period lasted an average of 73.4 days and service period – 98.7 days, and in patients, after the prescribed treatment – respectively 116.3 days and 197.4 days.

The major components of economically useful traits in cattle dairy productivity, which conducted the selection is milk productivity and reproductive ability of cows. Studies conducted on animals Ukrainian black and white dairy cattle in the «Milk River» farm in the Sokal and Brody offices breeding reproducers «Breeder» Lviv region and plant breeding «Yamnytsya» Ivano–Frankivsk region. Ukrainian black and white dairy breed in the western region of Ukraine is characterized by good reproductive ability. Depending on the husbandry and lactation duration, service period lasted within 87.4 – 121.5 day, intercalving period – within 364 – 402.6 day, dry period within – 47.3 – 72.9 day, the fertility index was 46.3 – 48.0, coefficient of reproductive ability – within 0.92–0.99,  output of calves per 100 cows – within 91.8 – 98.8. The duration of pregnancy in cows of different  farms and lactations were in range 277 – 283.5 day and meet the requirements of the physiological norm. It has been shown that the milk yield of cows depends on the parameters of reproductive capacity. The correlation between duration of service–period and intercalving period, and milk yield, milk fat in most cases was positive. Correlation dry period duration and parameters of milk yield changed from negative to positive. Depending on the husbandry, lactation and index the impact share of service–period duration on milk yield was 7.0 – 29.7, for intercalving period – 8.8 – 31.8, for dry period – 9.2 – 23.8% respectively.

Дана оценка причин выбраковки дойных коров из стад, определена продолжительность их жизни, установлены соотношения МДЖ и МДБ в молоке коров и на основании этого выявлены взаимосвязи с содержанием кетоновых тел в молоке и некоторыми показателями воспроизводства. Наиболее часто животные выбывают из стада в связи с гинекологическими заболеваниями — 45,9%, за первые 100 дней лактации — 42,05%. Продолжительность жизни коров, выбракованных вследствие инфекционных и инвазионных болезней, является минимальной и составляет 4 года, у коров, выбывших по причине внутренних незаразных и хирургических болезней, на 15 и 20% больше. При соотношении массовых долей жира и белка (СЖБ) 1,10 и менее содержание бета-гидроксимасляной кислоты (БОМК) в молоке достоверно (на 80%, P<0,01) превышает данный показатель у животных с оптимальными значениями СЖБ. У коров с оптимальным СЖБ уровень ацетона в молоке был выше порогового на 28,57%, а у животных с низкими значениями СЖБ достоверное превышение составило 42,85% (P<0,05). Особи с СЖБ ниже оптимальных значений в первые 100 дней характеризовались более длительным периодом лактации в целом на 8,57%, в то время как у животных с оптимальным СЖБ ее продолжительность приближалась к стандартной и составила 308,13 дня (P<0,001), межотельный период был на 5,39% менее продолжительным (P<0,001). При оптимальных значениях СЖБ длительность сервис-периода равнялась 112,91 дня, что на 14,73% короче (P<0,001) продолжительности сервис-периода у животных с низкими значениями СЖБ. The analysis of the reasons for leaving dairy cows from the herd was carried out. The life expectancy of cows has been determined. The ratios of fat to protein mass fractions in cow's milk have been established. The relationship between the content of ketone bodies in milk and reproductive indicators in animals was revealed. Most often, animals leave the herd due to gynecological diseases (45.9%), and in the first 100 days of lactation (42.05%). The life expectancy of cows culled due to infectious and invasive diseases is minimal and amounts to 4 years. For cows abandoned due to internal non-communicable and surgical diseases, life expectancy was 15 and 20% longer. When the ratio of mass fractions of fat to protein was 1.10 or less, the content of beta-hydroxybutyric acid in milk significantly (by 80%, P<0.01) exceeded this indicator in animals with optimal values of the ratio of fat to protein. In cows with an optimal fat to protein ratio, the acetone level in milk was 28.57% above normal. In animals with a low value of the ratio of fat to protein, the significant excess was 42.85% (P<0.05). Animals with a ratio of fat to protein below the optimal value were characterized by a longer lactation period in general by 8.57%. In animals with an optimal fat-to-protein ratio, the duration of lactation approached the standard one and was 308.13 days (P<0.001), and the interbody period was 5.39% shorter (P<0.001). With optimal values of the fat-to-protein ratio, the duration of the service period was 112.91 days, which is 14.73% shorter (P<0.001) than the duration of the service period in animals with low values of the fat-to-protein ratio.

AbstractThe aim of the study was to evaluate the slime-producing ability of coagulase-negative staphylococci (CNS) isolated from clinical and subclinical mastitis in cows. The study was carried out on 100 isolates of CNS obtained from milk of 86 cows from farms located in the Lublin region (Poland). Slime-producing ability was observed in over half of coagulase-negative staphylococci (54.0% of isolated CNS), including 19 isolates of methicillin-resistant staphylococci (95.5% of all MRCNS). Of 22 isolates of CNS responsible for the clinical form of mastitis, 20 isolates (90.9%) produced slime: S. xylosus (7 isolates), S. haemolyticus (6 isolates), S. chromogenes (4 isolates), and S. sciuri (3 isolates), including 9 isolates of MRCNS (45.0%). The remaining 34 isolates of CNS (43.6%) with the ability to produce this exopolysaccharide were isolated from the milk of cows with subclinical form of mastitis: S. xylosus (12 isolates), S. sciuri (9 isolates), S. chromogenes (6 isolates), S. haemolyticus (3 isolates), S. warneri (3 isolates) and S. saprophyticus (1 isolate), including 10 isolates of MRCNS (12.8%).

The article presents the results of the analysis of the reproductive ability of cows depending on the level of their milk productivity. The studies were conducted in the Republic of Mari El on cows of the Holstein black-and-white breed (n = 3828). There have been studied the influence of different levels of milk yield on the duration of the service period and period between calvings, the output of calves per 100 cows, the coefficient of reproductive ability. The studies used the comparison method, correlation, regression and one-factor analysis of variance. It has been established that the milk yield increases with the age of cows, but at the same time the duration of the service period and calving interval increases. In first-calf cows, the service period was 128.8 days (Cv = 75.1 %), the calving interval was 403.6 days (Cv = 23.5 %). By the third lactation, with an increase in milk yield by 1030 kg (15.4 %), the duration of the service period increased by 7.2 days (5.6 %), the calving interval  -by 12.3 days (3.0 %). The share of the impact (ƞ2x) of milk yield on the duration of the service period was 5.4 %, the calving interval -4.7 %. The correlation coefficients between milk yield for 305 days of the first lactation and the duration of the service period and calving interval were 0.24 and 0.22 (p<0.05), with milk yield for the entire lactation 0.81 (p<0.05). The optimal indicators of the service period (89.4 days), the calving interval (369.4 days), the reproductive capacity (0.94) and the output of calves (1.0) were possessed by the first heifers with low milk productivity-milk yield less than 5000 kg of milk. In animals with the milk yield of 6000-9000 kg of milk or more, the duration of the service period was 12.4-249.6 % higher, the calving interval -by 1.9-32.5 % (p<0.05). According to the regression coefficients, on average, each increase in milk yield per 1000 kg increased the duration of the service period by 25.9 days, the calving interval -by 23.1 days, which worsened the output of calves by 0.24 %, and the coefficient of reproductive ability decreased by 16.0 %.

The paper presents the results of studying the effect of sire lineage on reproductive qualities and milk yield of cows. The study was carried out inIrkutskregion on a herd of Holsteinized black-andwhite cattle of Pribaikalsky type. The analysis of the main characteristics of reproductive capacity of herd cows on a farm was performed during 2013–2018. The material of the research work was based on the informational database of animals from the program of breeding register Selex. Cows were divided according to sire lineage and milk productivity into five groups by the level of milk yield: from 5000 to6500 kg, 6501-8000, 8001-9500, 9501-11000 and more than11001 kg. Successful insemination of heifers took place at the age of 15.7-16.6 months with the live weight of more than400 kg, which corresponds to zootechnical standards. The earliest (15.7 months) insemination was in heifers of Reflection Sovereign sire line, the age of first calving was 753 days with the live weight of561 kg. The latest (498 days) successful insemination was observed in heifers of Montvik Chieftain bull line with the live weight of498 kg. Cows of Sealing Trygen Rocket (8766 kg) and Reflection Sovereign (8704 kg) sire lines had the highest milk productivity with a significant difference (p ≥ 0.90). The cows of these lines had the longest service period (164 and 179 days), as well as the length of the calving interval (445 and 458 days), respectively. The coefficient of reproductive capacity of cows of different sire lines ranged from 0.80 to 0.88, which is a low indicator.
