“…Transition period in dairy cows is dominated by a chain of metabolic adaptations including dramatic changes in endocrine status to support lactation and avoid metabolic disorders (Pascottini et al, 2020). The practical purpose of the nutritional strategies during this timeframe is to support these metabolic changes as there is a sudden and marked increase in nutritional requirements for milk production when nutrient supply lags far behind.…”

Background: The term “transition” comprises the various important physiological, metabolic and nutritional changes in the productive cycle of the cattle. It influences lactation, nutritional status, postpartum diseases and reproductive performance of the animal. It is, therefore, important to elaborate various nutritional strategies in this phase for optimizing productivity and minimizing health problems. A preliminary study was conducted to evaluate the influence of fat and protein along with indigenous traditional knowledge-based polyherbal preparation supplementation on reproductive and immune parameters of periparturient crossbred cows. Methods: Twenty-seven pregnant Karan Fries cows, in their last trimester were selected and divided into 3 treatment groups (T1, T2 and T3) consisting of nine animals each, based on most probable production ability (MPPA; 3002 kg) and body weight (423 kg). Cows of groups T1 (control), T2 and T3 were given TMRs having 13.1, 13.1, 16.1% crude protein (CP) and 9.82, 9.82, 10.8 MJ/kg metabolizable energy (ME) respectively, during pre-partum period. Whereas, during post-partum period, cows were offered TMRs containing 14.0, 16.8, 16.8% CP and 10.2, 11.0, 11.0 (MJ/kg) ME, respectively. T2 and T3 groups were also supplemented with polyherbal preparation post-partum. Result: The results revealed that cows in T2 and T3 group had lower incidence of retained placenta, cervicitis, metritis and better conception rate than cows of control group. Also, dietary treatments facilitated early involution of pre gravid uterine horn (P less than 0.05). Plasma total immunoglobulins (mg/ml) concentration was found to be significantly (P less than 0.05) higher in T3 group followed by T2 group. Hence, it was concluded that increasing energy and protein levels along with polyherbal mixture supplementation during transition period reduced periparturient stress and improved reproductive performance of dairy cows.

“…For example, cows undergo a significant shift in their hormonal status and metabolic profile during the period of pregnancy. In particular, with increasing periods of pregnancy, the content of estrogens and progesterone in the blood of cows significantly increases, the concentration of total lipids, cholesterol, and glucose increases (Edelhoff et al, 2020;Kaurivi et al, 2020;Pascottini et al, 2020).…”

The article describes the results of the research on the formation of the bone system of the carcasses of purebred and crossbreed steers. Three groups of animals were selected for the experiment by the analog method. The first group consisted of purebred steers of Simmental breed, the second and third groups consisted of ½ blooded steers of Simmental and Charolais beef breeds, respectively. The dynamics of age changes in the skeleton were studied by determining the absolute relative weight and calculating the growth coefficient. The research showed that the absolute weight of the skeleton has increased with the development of the test steers. Thus, if the skeleton mass of newborn steers was 7.44, 7.34, and 8.30 kilos for each group, then at the age of 6 and 12 months, it had increased to 29.

“…This study evaluated the relationship between the serum NAb titers and the BHBA and NEFA concentrations in the prepartum and postpartum periods in Tuj and Hemşin sheep. While no previous studies exist on NAb titers in sheep, it is known that metabolic and stress factors lead to changes in the immune system in cows during the transition from pregnancy to lactation [ 23 , 24 ]. It is reported that the NAb concentration in blood and milk during the early lactation period reflects the metabolic health status and that the NAb concentration and activation increases in pregnant cows [ 3 ].…”

Determination of natural antibodies, beta-hydroxybutyric acid, and non-esterified fatty acid levels in the serum of peripartum Tuj and Hemşin sheep

Background and Aim: Many metabolic and immunological changes occur during the transition period. Innate immunity plays an important role against to infections and natural antibodies (NAb) are important in immunity. This study aims to determine a connection between serum NAb titers, beta-hydroxybutyric acid (BHBA), and non-esterified fatty acid (NEFA) concentrations in Tuj and Hemsin sheep during the peripartum period. Materials and Methods: Serum NAb, BHBA, and NEFA levels were determined from the blood samples collected from Tuj and Hemsin sheep on days 30 and 15 before birth, on the day of birth (day 0), and on days 15 and 30 after birth. Results: NAb titers were found to be higher in Tuj than in Hemsin sheep (p<0.001). No statistically significant difference was found in serum BHBA concentrations of both breeds on all sampling days (p>0.05). The serum NEFA level was lower in Tuj sheep in the last 15 days of pregnancy compared to Hemsin sheep (p<0.05), while no difference was found in samples collected at the other time points. Conclusion: This study indicated that serum NAb titers significantly changed in Tuj and Hemsin sheep during the transition period. Serum BHBA and NEFA concentrations increased during the last stages of pregnancy and decreased after birth. Based on these findings, it is suggested that the immunological status could vary by the breed of sheep or various factors that affect the sheep's metabolic state.
