In vitro fertilization (IVF) technologies have great potential in the preservation of endangered species. In the current study, an IVF experiment was carried out to evaluate whether reproductive technologies are suitable for Kazakh Whiteheaded cattle, aimed at preserving this breed whose population has reduced drastically over the last thirty years. The reproduction characteristics of Kazakh Whiteheaded cows were compared to Aberdeen Angus cows. Transvaginal ultrasound-guided ovum pick up sessions were carried out followed by in vitro embryo production and embryo transfer and pregnancy diagnosis. The total and viable oocytes per OPU procedure were 12.8 ± 1.18 and 8.7 ± 0.85 for the Aberdeen Angus breed, and 8.8 ± 1.04 and 6.2 ± 0.83 for the Kazakh Whiteheaded breed. Similarly, the mean number of cleaved oocytes and morula/blastocyst stage embryos produced by OPU/IVF were 4.8 ± 0.49 and 1.4 ± 0.15 for the Aberdeen Angus breed, and 2.4 ± 0.46 and 0.18 ± 0.05 for the Kazakh Whiteheaded breed (p ≤ 0.02). From fifty Kazakh Whiteheaded donor animals, 2585 oocytes were aspirated following six ovum pick up sessions. One thousand eight hundred and seventy-six (72.5%) oocytes were chosen for maturation and were further fertilized. The number of embryos cleaved was 720 (38.3% out of oocytes fertilized) on day four post-fertilization. Of these cleaved embryos, 56 (7.5%) developed into the late morula/blastocyst stage on day seven post-fertilization, averaging 1.12 embryos per donor animal. Pregnancy was detected in 12 recipients; 4 healthy calves have been born to date. The outcomes of our study have demonstrated that reproductive technologies can be applicable in preserving the endangered Kazakh Whiteheaded cattle. The findings in this report will enhance knowledge of the reproductive characteristics of endangered domestic animals and help develop sophisticated reproductive protocols for animals with unique reproductive mechanisms.

The study was conducted in 2024 at the «Lbishin» farm in Akzhaik District, West Kazakhstan Region, and focused on early pregnancy diagnosis in Kazakh White-headed cows. A total of 70 pregnant cows were examined, with 12 selected for in-depth analysis at different stages of gestation (3rd, 4th, and 5th months). The study employed a comprehensive diagnostic approach including rectal palpation, ultrasonography, blood biochemical and hematological tests, milk analysis, and rapid progesterone-based tests. Rectal palpation proved effective in identifying gestational changes in uterine structure, fetal mobility, and anatomical development. Ultrasonography enabled visualization of the fetus and its physiological parameters, including heart rate, position, and blood supply. This technique was particularly valuable in detecting abnormalities and ensuring fetal viability at early stages. Biochemical analysis of blood serum revealed significant physiological shifts: albumin levels declined with gestation, while total protein, ALT, and urea levels increased, indicating metabolic adaptation. Glucose concentrations remained below reference values throughout, possibly reflecting energy redistribution for fetal needs. Hematological results showed a progressive rise in erythrocytes, hemoglobin, and hematocrit, consistent with increased oxygen demand during pregnancy. Leukocyte subpopulations also changed markedly, suggesting immune modulation. Platelet indices increased, indicating adjustments in coagulation function. Milk analysis revealed a consistent increase in fat, protein, and density values with gestation progression, supporting the use of milk parameters as auxiliary pregnancy indicators. Rapid tests effectively identified progesterone-related hormonal changes. The integration of various diagnostic methods provided high accuracy and reliability in determining pregnancy and assessing reproductive health.

Rational and successful use of antibiotics in the treatment of infectious animal diseases is possible provided if the sensitivity of the isolated pathogen to antimicrobial drugs is determined. An article is devoted to study and analysis the sensitivity and resistance of Staphylococcusspp. to various antibacterial drugs. Carnivores (dogs) were used as objects of study from which biomaterial was collected and laboratory studies were carried out according to the generally accepted method for carriage of pathogenic Staphylococcus. Clinical material taken from the pharynx, nose, urine and cervical canal of the uterus of animals was subjected to bacteriological examination. Antibiotic sensitivity was determined by the classical disk-diffusion method on Mueller-Hinton medium. The analysis allowed establishing a high level the Staphylococcus aureussensitivity to antibiotics –ceftriaxone, clarithromycin, cefepime, azithromycin. So, in the biomaterial taken from urine, S.aureuscolonies were sensitive to ceftriaxone (growth inhibition zone 28 μm), cefepime (growth inhibition zone 17 μm), ampicillin (growth inhibition zone 26 μm). However, Staphylococcus aureusisolated from urine was least sensitive to azlomycin. S.aureuscolonies were sensitive to ampicillin and clarithromycin in biomaterial obtained from the cervical canal. In the biomaterial taken from the nasal cavity, S.aureuscolonies weresensitive to ampicillin and clarithromycin

Мақалада авторлар өзіндік зерттеулер нәтижесінде 300 бас герефорд сиырларының күйтін келтіру мақсатында синхронды зерттеу және ғылыми-өндірістік тәжірибе жүргізілді. Соның нәтижесінде мал шаруашылығы жағдайында төлдеуді маусымдық кезеңге ауыстыруға арналған гормоналды өңдеуді қолдану арқылы жыныс циклінін ынталандырудың тиімді әдісі әзірленді. Мал шаруашылығының алдында тұрған міндеттерді табысты шешу жолдарының бірі қолдан ұрықтандыру сияқты биотехнологияның әдістерін тиімді пайдалану болып табылады. Сондықтан қолдан ұрықтандыру жөніндегі жұмыстағы кез келген оңайлатулар аналықтардың ұрықтану нәтижелеріне кері әсер етеді. «Масақбай-Инвест» ЖШС Герефорд тұқымын өсіруді қарқындату және олардан жоғары сапалы өнім алу – ветеринариялық және зоотехниялық ғылымның негізгі міндеттері. Бұл сұрақтарды шешуде ветеринариялық акушерлік және гинекология мыңызды рөл атқарады. Қолдан ұрықтандыру барысында селекцияның ұйымдастырушылық техникалық негізін ескере отырып, әр түрлі тәсілдерін қолдану барысында тиімді әдісін бөліп көрсетуге болады.Осы бағытта жұмысымыздың негізгі бөлігі болып Канада елінен әкелінген және "Асыл-түлік" АҚ бұқаларының ұрықтарымен ұрықтандырылған сиырлардың ұрықтану қабілеттілігін салыстырмалы түрде анықтау. Канадтық бұқалардың ұрығымен ұрықтандырылған 150 бас сиырлардан 123 бас бұзау , ол дегеніміз 82 пайызды көрсетті, ал «Асыл-түлік» бұқаларының ұрықтарымен ұрықтандырылған 150 бас сиырлардан 101 бас бұзау алынды, ол дегеніміз 67 пайызды құрады. Сонымен, 1-ші топтағы сиырлардан, 2-ші топтағы сиырларға қарағанда 22 бұзау (яғни 15 пайыз) бұзау көп алынды.
