“…To optimise the schedule of artificial insemination of groups of animals kept in different buildings, an additional study of detected cows on day 0 of the induced sexual cycle before insemination was performed by differential palpation diagnostics of morphofunctional and morphometric features of the ovaries, using a modified cyclic technique provided in sourses ( Sidashova, 2017;Sidashova, 2021). Induction of cows` sexual activity in was performed according to the standard OvSyng hormone synchronisation protocol (day 0 -Ovarelin 2.0 ml intramuscularly; day 7 -Enzaprost 5.0 ml intramuscularly; after 56 hours -Ovarelin 2.0 ml intramuscularly; after 16 hours -artificial insemination on day 10 day of the scheme).…”

An important part of reproduction management programmes on dairy farms is the detection of infertile cows and early re-insemination to achieve higher rates of pregnancy. The purpose of the study was to investigate the features of gonadal morphogenesis in high-yielding cows in the conditions of industrial keeping technology on day 0 of the sexual cycle in vivo in real time. Structural, comparative, and statistical methods were used, as well as biotechnical methods of palpation cyclic examination of ovaries with differential diagnosis of morphophysiological or pathomorphological indicators. The results of diagnostics of the ovaries of dairy cows (n=128) on day 0 of the induced cycle detected by step activity sensors showed a significant structural polymorphism of these organs of the reproductive system. It was found: from 66.67% to 30.77% of cows with a physiological course of the follicular phase of the cycle, i.e., on day 0, a preovulatory follicle or the beginning of ovulation on the ovaries (subject to a decrease in the number of cows suitable for insemination with increasing lactation duration from 50-75 days to 211-306 days (P<0.001). Hypogonadism was diagnosed in 19.45% of cows, and in 61.11% – ovarian dysfunctions with the manifestation of cystic follicular degeneration; 19.44% of cows at the time of the study had irreversible chronic adhesive processes of the genital tract tissues in the “ovary+oviduct” area (ovophoritis and ovosalpingitis in latent form), which allowed for pregnancy to occur, with a pronounced tendency to increase this gonadopathy with an increase in lactation (respectively: 50-75 days – 0.00%; 76-160 days – 22.22%; 161-210 days – 22.22%; 211 and more – 33.33%; p<0.05). The trend of influence of subclinical disorders in the metabolism of cows of the experimental herd on the indicators of the biochemical composition of blood serum and the symptom of ovarian dysfunctions was investigated. Thus, the in vivo morphological and pathological profile of the ovaries of high-yielding cows on day 0 of the sexual cycle was established, which allowed optimising the artificial insemination regime and reduce economically nonprofitless sperm consumption. The results can be used in the practical work of veterinary medicine doctors, researchers, and applicants for higher education in veterinary and biological science

LLC LIVESTOCK4EXPORT specializes in fattening cattle of specialized meat breeds, i.e., Aberdeen-Angus, Limousin, Simmental and local animals obtained by crossing the Belgian blue breed with the Ukrainian red-spotted and black-spotted breeds. Nowadays the meat sector of the economy needs to find ways to increase the efficiency and profitability of production. The creation of interbreeding herds based on the industrial crossing of dairy and dairy-meat cows with meat breeders is an important reserve for increasing meat resources. LLC LIVESTOCK4EXPORT inseminates cows in the private sector with the purchased sperm of the Belgian blue breed. Then the farm buys and fattens these young calves with a live weight of 55 to 120 kg until they reach a live weight of 300–400 kg with further sale abroad. According to the results of the fattening of meat cattle of various breeds at LLC LIVESTOCK4EXPORT, interbreeding animals had the best growth rate. The adopted technology of growing and fattening animals at LIVESTOCK4EXPORT LLC ensures obtaining average daily gains at the level of 1,706 g reducing feed consumption and livestock fattening times. The advantage in terms of average daily growth of crossbred young is confirmed by the effect of heterosis and the gene of double musculature in crossbreds of the first generation, which significantly increases their meat productivity. They use the same type of year-round feed for animal fattening. In the farm, animals are fed ad libitum according to the developed structure of the diet with 90 % special compound feed and 10 % straw or hay. The composition of special compound feed includes 270 kg/t of corn grain, 190 kg/t of wheat, 150 kg/t of barley, 150 kg/t of malted grain, 110 kg/t of wheat bran, 70 kg/t of sunflower meal, 35 kg/t of soybean cake, 20 kg/t of premix concentrate, and 5 kg/t of sunflower oil. Animals have free access to water and roughage. Keeping animals on the farm is year-round untethered with free access from the premises to the feeding grounds (feedlots).

“…Як свідчать дані таблиці 1, в складі групи знаходились корови різного віку (від першої лактації до шостої), ріст їх молочної продуктивності показав вірогідний корелятивний зв'язок за підвищення терміну експлуатації до четвертого отелення з деяким падінням у більш старших корів. Це співпадає з висновками більшості авторів щодо росту продуктивного потенціалу з віком у корів вітчизняної селекції, серед них і новоствореної української червоної молочної породи (Gulsen, 2010;Sidashova et al, 2018;2022). У сучасному молочному скотарстві нормування і характер складу, зовнішнього вигляду мінеральних добавок для великої рогатої худоби за останні роки значно змінився.…”

“…Послідовний розгляд сигналів корів, починаючи від рідких явищ спотворення смаку до виявлених випадків злущення слизової оболонки кишечнику (що характеризує патологічні зміни морфології тканин стінки кишечнику) на тлі субклінічних відхилень показників біохімії крові та низького рівня перетравності кормів (дисбактеріоз), висвітлює узагальнену картину зниження адаптивності організму піддослідних тварин до умов інтенсивної експлуатації. Таким чином, спостереження за поведінкою корів на спаді лактації демонстрували сигнали щодо неочевидної в щоденних умовах реального виробництва картини поступового накопичення латентних симптомів поліморбідності, які можуть бути вагомими причинами кардинального зниження строків продуктивного використання поголів'я спеціалізованих молочних порід, що було показано у наших попередніх дослідженнях (Sidashova et al, 2022). За сучасними науковими уявленнями, мікрофлора кишечника є одним із важливих факторів забезпечення фізіологічного травлення і функціонального стану слизової кишечнику, а у кінцевому результаті -всього організму в цілому (Yong, 2002;Duda, 2010;Rybachuk, 2020).…”

The results of a comprehensive examination of a group (n = 179) of high-yielding cows of the second half of lactation (more than 200 days) with diagnosed pregnancy (80–225 days of pregnancy) during 30 days of visual observation, among which 6 individuals (3.35 %) were found. symptoms of altaphagia (distortion of taste). Analysis of the biochemical profile of blood serum showed the presence of a number of subclinical abnormalities in a number of indicators, namely (in parentheses are the reference values): Ca/P – 0.92 units (1.1–1.6); total protein – 50.52 g/l (70–85); albumin/globulin – 3.63 units (0.6–1.3); ALT – 35.32 g/l (10–30); AST – 97.32 g/l (10–50); creatinine – 186.10 μmol/l (80–130); alkaline phosphatase – 323.38 units (100–200); urea – 5.08 mmol/l (3.5–6.0). Due to the fact that the active livestock of the dairy complex was provided with fodder base, timely addition of optimized according to modern standards complete mixed diet with 4 % mineral premix, the main causes of biochemical metabolic disorders can be considered dysfunction of intestinal microbiota, digestive and protective functions. of the mucous membrane due to chronic latent inflammatory processes, which was confirmed by the results of the assessment of feed transit (40.09 % of the remains of the daily diet of cows remained after washing of manure samples, which differed in a significant amount of undigested feed components and the inclusion of exfoliated necrotic particles of the mucous membrane). The latent course and accumulation of alimentary pathologies of the digestive tract contributed to the formation of a negative background for the symptoms of endogenous hunger in cows, manifested by signs of altrophagia, which were only clinical and ethological signals of chronic metabolic disorders in many high-yielding lactation groups. Given the importance of maintaining a high physiological status of dairy cows for profitable dairy production, the need to continue research to study the ethological signals of animals remains relevant to find effective means of preventing foodborne illness, including normoflorization of digestive mucosa.
