Проведены исследования по применению кормовой добавки (КД) из нетрадиционных региональных растительных ресурсов: лишайников Cladonia alpestris и Cetraria islandica, морских водорослей (ламинария Laminaria, фукус Fucus) и микроэлементов в рационах кормления коров за 2 мес перед и 2 мес после отела. Использование КД положительно влияло на молочную продуктивность. Наибольшая эффективность ее применения в рационе коров проявлялась в повышении среднесуточного удоя на 1,67 кг (11,4%), жирномолочности — на 0,25 абс.%, содержания белка в молоке — на 0,06 абс.% относительно контроля. Применение КД позволило оптимизировать воспроизводительные функции. У коров опытной группы сервис-период был короче на 24,8%, индекс осеменения меньше в 0,75 раза, чем в контроле. Оплодотворяемость от первого осеменения также была выше у опытных коров (62,5—87,5%). Животные, получавшие дополнительно к основному рациону КД, обладали повышенной воспроизводительной способностью по сравнению с аналогами, не получавшими ее, что позволило успешней использовать первых в процессе воспроизводства стада. Включение в рацион кормовой добавки способствует и повышению экономической эффективности производства. Снижение уровня убыточности в сравнении с применением хозяйственного рациона составило 16,2 п.п. Улучшение всех гематологических показателей сыворотки крови коров показывает, что использование КД оказывает положительное влияние на их организм. На основе результатов исследований разработана кормовая добавка для кормления крупного рогатого скота с использованием нетрадиционных источников кормов в условиях Магаданской области, получен патент на изобретение «Кормовая добавка для крупного рогатого скота с иммуномодулирующим действием». The studies have been carried out on use of feed additive of nontraditional regional  plant resources: lichens, seaweeds, and trace elements in diets for cow feeding for 2 months of dry period and 2 months after calving. Use of the feed additive (FA) influences positively on the milk productivity. The highest efficiency of use of the FA in cattle diet showed in increasing average daily milk yield by 1.67 kg (11.4%), milk fat content by 0.25 absolute percent, milk protein content by 0.06 absolute percent, relative to the control group. Use of the feed additive enables optimizing reproductive function of the cows. The cows in the 2 experimental group had a service period shorter by 24.8%, insemination index lover 0.75 times than those in the control group cows. Fertility from the first insemination was higher in experimental cows (62.5-87.5%). The cows fed the FA in addition to the basic diet have a heightened reproductive abilities as that did not feed it which makes it possible to use the former in the process of the herd reproduction. The inclusion of a feed additive in the diet also contributes to increasing the economic efficiency of production. The decrease in the level of unprofitability in comparison with the use of the ration was 16.2 percentage points. Data of haematological investigations showed that, according to studied  indices, the state of the cows in the experimental groups had improved in comparison wilh ones in the control group. On the basis of results of the studies, a feed additive for cattle feeding has been developed using the nontraditional feed resources in conditions of Magadan region and a patent has been taken out for an invention entitled «Feed additive for cattle possessed an immunomodulating effect».

Изучено влияние на репродуктивную функцию коров белково-витаминно-минеральных концентратов (БВМК) с кормовой добавкой «AMG-COMPLEX», состоящей из эфирных масел и растительных экстрактов. Для проведения опыта были сформированы контрольная и опытная группы по 70 голов с учетом количества дней до отела из коров второй и третьей стельности. Животным контрольной группы скармливали основной рацион. Для коров опытной группы были составлены рационы с БВМК, которыми заменяли пропорциональное количество концентрированных кормов и часть витаминно-минерального премикса. Они получали БВМК для сухостойных коров в количестве 300 г на 1 голову в сутки с 60-го по 20-й день до отела и по 200 г на 1 голову в сутки с 20-го дня до отела. После отела 60 дней им скармливали БВМК для раздоя в количестве 1200 г на 1 голову в сутки. Использование БВМК в рационах коров опытной группы способствовало улучшению у них репродуктивной функции и снижению частоты гинекологических заболеваний после отела в 4,5 раза. Индекс осеменения в опытной группе составил 1,73 (P≤0,05), что на 0,76 ниже, чем у животных контрольной группы. Средняя продолжительность сервис-периода в опытной группе составила 87,71 дня (P≤0,01) и была короче, чем в контроле, на 14,72 дня. The effect on the reproductive function of cows of the protein-vitamin-mineral concentrate with the feed additive ʺAMG-COMPLEXʺ, consisting of essential oils and plant extracts, was studied. To experiment, taking into account the number of days before calving, control and experimental group of 70 heads each were formed from cows of the second and third pregnancy. In the scientific and economic experiment, the cows of the control group consumed the feed of the main rations. For the cows of the experimental group rations were made with PVMC, which replaced the proportional amount of concentrated feed and a part of the vitamin-mineral premix. They received PVMC deadwood in the amount of 300 g per 1 head per day from 60th to 20th day before calving and 200 g per 1 head per day 20 days before calving. 60 days after calving they received PVMC lactation in the amount of 1200 g per head per day. Feeding PVMC to cows of the experimental group contributed to the improvement of reproductive function and a decrease in the frequency of gynaecological diseases after calving by 4.5 times. The insemination index in the experimental group was 1.73 (P≤0.05), which is 0.76 lower than in the animals in the control group. The average duration of the service period in the experimental group was 87.71 days (P≤0.01) and was shorter than in the control by 14.72 days.

Milk yield, milk ingredients, health and other, production-related parameters of subclinically infected, Mycobacterium avium ssp. paratuberculosis (MAP-) shedding (positive faecal PCR, n = 20) and non-shedding (negative faecal PCR, n = 10) dairy cows were compared in the period from 10 days prepartum to 120 days postpartum. Body condition, rumen fill and faeces scores were lower in the MAP-shedding cows. There was no significant difference in plasma or urine metabolic parameters between the groups. Milk yield and lactose content tended to be lower (P = 0.074 and 0.077, respectively), somatic cell count tended to be higher (P = 0.097), while milk fat content was significantly higher (P = 0.006) in MAP-shedding cows than in the controls. Milk protein content did not differ between the groups. All other health and production parameters [number of reproductive tract treatments, number of udder treatments, number of artificial inseminations (AIs), calving interval, and service period] were significantly better in the control group. It is concluded that MAP infection, even in a subclinical form, has a significant impact on some production and health parameters of dairy cows.

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 Impact

SummaryThe following trial was conducted to evaluate the impact of feeding Yea-Sacc® (YS; Alltech Inc, USA), a zootechnical feed additive based on a live probiotic strain of Saccharomyces cerevisiae, to lactating dairy cows over a 12 week period. Sixty-four primiparous and multiparous Holstein dairy cows, grouped to give similar range of parity, physiological and milk production stages, were selected for the study. Cows were equally allocated to either a control feed group or a diet supplemented with YS (32 cows per treatment). The test diet was formulated to include YS (Yea-Sacc® Farm Pak) incorporated in the total mixed ration (TMR), supplying a target dose of 5 × 107 CFU/kg feed dry matter (DM). This target dose delivered 1 × 109 CFU/cow/day, for a cow consuming 20 kg feed (DM basis) daily. Each cow was considered a replicate unit. Cows were fed a nutritionally adequate total TMR plus hay and a supplementary protein/energy concentrate (calculated according to milk yield) for 12 weeks, supplied once a day after the morning milking. Weigh backs of feed were recorded daily, with refusals being maintained at 3% of the total intake. During the 12 week study period, YS had significant beneficial effects on milk production (+0.8 kg/day; P = 0.003), energy corrected milk production (+1.4 kg/day; P < 0.0001), synthesis of milk protein (+36 g/day; P = 0.001), milk protein content (+0.3 g/kg; P = 0.009), and milk urea content (−0.09 mg/l; P = 0.004). The synthesis of milk fat was similar between treatments but milk fat content was lower for the YS group compared to the control group (−1.1 g/kg; P = 0.0002). Lactose content was always higher (+0.8 g/kg; P < 0.0001) for the YS group, indicating enhanced energy utilisation. In general, the effect of YS was higher during the first study period (one to seven weeks), when cows were in early lactation and the production potential was higher. YS cows produced significantly more milk during the study, and an additional 220 kg milk per cow was sold from this group from the output measured from the beginning of the study to two weeks post-trial. However, the statistical analysis including the post-study period did not show a significant effect. The 305-day simulated milk production was higher for the YS group (+400 kg/cow) but again the difference was not significant. In conclusion, YS at a target dose of 5 × 107 CFU/kg DM improved milk production and milk quality in healthy dairy cows. In addition, when the data were included in a whole-farm model, feeding YS reduced methane emissions by 4%, reduced the number of animals required for the desired milk production by 4% and increased overall farm margins by 1.4%.

The article examining the implication for the microelements’ salts – cobalt and copper – to milk production, vitamin A and trivitamin (vitamin A, D3, E) to the cows’ reproductive function in mountainous areas. The study is relevant due to the fact that when organizing cattle feeding, first of all, we care about the balance of rations for the main nutrients and only then for vitamins, minerals and micro minerals. That is why it becomes more important to provide the breeding stock with vitamins and increase the metabolism of the main substrate of life - protein, change its biological function. It is noteworthy that it is necessary to clarify the way that fat-soluble vitamins on cells act, so that their biological spectrum of action is wider than we realize. The purpose of this research is the further study of the biological role of trace elements and vitamins used in cattle breeding, considering the soil and climatic zones of mountainous areas. In our research, the mountainous farms cows’ feeding with microelements favorably affected their milk pr76nv hghhjhhnhghjuo9huyoduction. So, in animals from the second group, milk yield was higher compared to the control by 0.95 kg of milk, the third – by 1.28 kg and the fourth – by 1.45 kg. Calves from cows that received vitamin A and trivitamin developed better during the embryonic period and their birth weight was 2.8–3.0 kg more compared to the control group. Within 90 days after calving, 87.5–92 % of cows from the experimental groups became enceinte, while in the control group it was only 75 %.

Aim. To establish the effect of acidum succinicum on the activity of enzymes in the blood of cows after calving and the course of uterine involution. Materials and Methods. The study of enzyme activity was carried out in the Central Research Laboratory of I. Horbachevsky Ternopil National Medical University (Certificate of technical competence № 001/18, issued on September 26, 2018, valid until September 25, 2023). Results of the research. After the use of acidum succinicum in the body of cows of the experimental group, the activity of alanine aminotransferase increased by 12,0 % (p≤0,05), and the activity of aspartate aminotransferase, on the contrary, decreased by 30,0 % (p≤0,001), which indicates a positive effect on hepatocytes. Confirmation of this is the Ritis factor, which increased 1,4 times (p≤0,05). All animal experiments were conducted according to with the recommendations of ARRIVE and the British Animal Act 1986 and Directive 2010/63 / EU on the protection of animals for scientific investigation. In the body of cows of the control group, the activity of alanine and aspartateaminotransferases increased, respectively, by 14,0 % (p≤0,05) and 47,0 % (p≤0,001) against a background of a 1,2-fold decrease (p≤0,05) Ritis factor. A decrease in bilirubin content of 56,0 % (p≤0,001) in the body of cows after the use of acidum succinicum and an increase in its content by 2,2 times (p≤0,001) in the body of control cows indicates liver disease, which is accompanied by affection of its parenchyma, which may be a consequence of intoxication of their body in the last trimester of pregnancy. Conclusion. Acidum succinicum, applied to cows after calving, prevents the development of inflammation of the reproductive system, helps to restore reproductive function, reduces the duration of the service period to 80,0±2,0 days, and the insemination index to 1,3

Plant soot, as a novel feed additive, could not only improve digestive function but also adsorb mycotoxins and inhibit bacterial infections. The subchronic toxicity and prenatal developmental effects of plant soot were studied for the first time. Our results indicated that there was no subchronic toxicity in the range of 2,000–50,000 mg/kg plant soot added in the feed, and there was no significant difference in reproductive function, embryo development, and teratogenicity between the pregnant rats exposed to 312.5, 1,250, and 5,000 mg/kg plant soot and the control group. The maximum no-observed effect level (NOEL) of supplemental dosage in feed could be set to 50,000 mg/kg, and the maximum intragastric NOEL could be set to 5,000 mg/kg, which preliminarily provided guidance on daily additive amount or clinical protocols for plant soot, as well as promoting the development and application of this harmless antibiotic substitutes.

Содержание кальция (2,370,02 ммоль/л) в плазме крови животных опытной группы также превосходило (Р0,05) контроль (2,290,03 ммоль/л). Применение комплексного препарата на базе шрота расторопши дало выраженный экономический эффект дополнительный чистый доход на 1 голову за период эксперимента составил 27 175 руб. Применение препарата С значительно повышает продуктивность молочных коров, положительно влияет на биохимические показатели крови и является экономически обоснованным.The effect of a complex hepatoprotective preparation ( the feed additive S ) based on Milk Thistle meal (source of silymarin) on the cows of the precalving and early lactation period has been studied. The cows of the experimental group received 250 g/day of the feed additive S 21 days before and 21 days after calving, handling and feeding of the cows of the experimental and control groups being the same in everything else. On average, per day, cows in the experimental group gave milk 39.730.98 kg, which is 4.90.85 kg more (P0.01) than in the control group (34.820.78 kg). The content of milk fat and protein was higher in the experimental group than in the control group 3.710.15 versus 3.140.13 and 3.140.13 versus 3.080.09, respectively. Reliably lower values of bilirubin in the blood of animals in the experimental group (1.510.31 mol / l) in comparison with the control (2.130.31 mol/l) and higher values of the albumin level in the experimental group ( 37.390.89 g/l) in comparison with the control (34.690.75 g/l). The calcium content (2.370.02 mmol /l) in the blood plasma of animals of the experimental group also exceeded (P0.05) control (2.290.03 mmol/l). The use of a complex preparation based on Milk Thistle meal gave a pronounced economic effect an additional net income per head for the period of the experiment was 27 175 rubles. The use of the feed additive S significantly increases the productivity of dairy cows, positively affects the biochemical parameters of blood and is economically feasible.

Скармливание коровам в период раздоя синтетического полиоктилированного полисиликатного гидрогеля (ПОПСГ)  в количестве 100 г на 1 голову в сутки способствовало повышению среднесуточного удоя натуральной и базисной жирности молока на 7,74 и 16,0%, соответственно, и снижению затрат обменной энергии, сухого вещества, сырого протеина, концентратов на 1 кг молока базисной жирности на 13,0—13,6% по сравнению с аналогами из контрольной группы. Использование ПОПСГ способствовало снижению количества соматических клеток в молоке коров на 27,2% и повышению жира и белка на 0,28 и 0,07% по сравнению с контролем. Бактерицидная и лизоцимная активность крови новотельных коров  контрольной и опытной групп в конце опыта были практически на одном уровне и составили, соответственно, 68,59 и 67,03% и 0,31 и 0,30 мкг/мл. Показатель фагоцитарной активности крови у животных опытной группы равнялся 51,57%, что было выше контроля, соответственно, на 4,78%. Отмечено положительное влияние ПОПСГ на рубцовое пищеварение высокопродуктивных коров. Амилолитическая активность рубцовой микрофлоры в опытной группе животных была выше на 0,47 Е/мл. Общее количество бактерий и инфузорий в рубцовом содержимом подопытных коров находилось на одном уровне и составило в среднем 191,00—214,50 и 165,00—183,67 мг/100 мл рубцового содержимого, соответственно. Дополнительная прибыль от реализации молока коров опытной группы за период опыта равнялась 3258,72 руб. на 1 голову по отношению к контролю.Feeding cows in period of milking synthetic polyoxyling polysilicate hydrogel (SPPH) in the amount of 100 g per 1 head per day contributed to increasing the average daily milk yield natural and basis milk fat by 7.74 and 16.0%, respectively, and cost reduction of metabolizable energy, dry matter, crude protein, concentrates of 1 kg of milk basis of fat content is 13.0 to 13.6% in comparison with analogues from control group. The use of SPPH contributed to a decrease in the number of somatic cells in cow milk by 27.2% and an increase in fat and protein by 0.28 and 0.07% compared with the control. Bactericidal and lysozyme activity of blood of cows of the control and experimental groups at the end of the experiment were almost at the same level and amounted, respectively, 68.59 and 67.03% and 0.31 and 0.30 µg / ml. The indicator of blood phagocytic activity in animals of the experimental group was 51.57%, which was higher than the control, respectively, by 4.78%. The positive influence of SPPH on cicatricial digestion of highly productive cows. Amylolytic activity of the rumen microflora in the experimental group of animals was higher by 0.47 U/ml Total number of bacterias and protozoans in scar contents of the experimental cows was on the same level and amounted to an average of 191.00—214,50 and of 165.00—183,67 mg/100 ml scar content, respectively. Additional profit from the sale of milk of cows of the experimental group over the period of experiment was equal to 3258,72 RUB on the head relative to the control.
