AB  - This study examines the effect of season-related heat stress in dams on mineral status, and hematological profile of their calves. Ten Holstein dams (LowT group) were exposed to the 49-day-long period of low air temperature (5.2 ± 0.5 °C) and ten dams (HighT group) were exposed to a 53-day-long high air temperature (27.4 ± 0.4 °C). The dams' blood samples were taken one hour after parturition, while colostrum was sampled at 2, 14, and 26 h after calving. Ca, P, Mg, Na, K, Fe, Zn, Mn, and Se concentrations were significantly lower while Cu and Co concentrations were significantly higher at least in two examined colostrum sampling points in HighT group. Calf`s blood samples were taken before 1st colostrum intake, and on days 1, 2, 3, and 7 postnatal. Ca, P, Na, K, Fe, Cu, Zn, Mn, Se, and Co were significantly lower while concentration of Mg was significantly higher in calves that originated from HighT group at least at two examined sampling points. Season affected dam's blood mineral status but the pattern was not always the same as in calves, since Na, K, Cu, and Co were significantly higher in HighT group. Calves that originated from HighT group had significantly lower hemoglobin, hematocrit, MCV, MCH, and MPV values, as well as neutrophils and monocyte counts, while platelets, eosinophils, basophils, and lymphocyte counts were significantly higher. Season-related heat stress leads to a reduction of the most minerals in both dams' colostrum and calves' blood and certain minerals' deficiencies are linked to impaired calves' hematological adaptation.

AB  - Cow milk is widely consumed by human children and adults due to its nutritional value. Besides
nutrients, milk contains naturally occurring hormones, including insulin like growth factor-1
(IGF-1), that may alter their blood levels in the consumers. At the same time, the impact of IGF1 on human health is still unclear and controversial. The aim of the study was to determine IGF-1
concentrations in cow colostrum and milk and to discuss them from the aspect of human health.
Twenty Holstein cows were enrolled in the study and subjected to colostrum, milk and venous
blood sampling in order to determine the IGF-1 concentration by the radioimmunoassay (RIA).
Colostrum was sampled at 2, 14 and 26 hours (1st, 2nd and 3rd colostrum) after calving, while
milk and venous blood were taken 10 days after calving. The concentration of IGF-1 was the
highest in the 1
st colostrum and decreased significantly with each subsequent sampling, so the
lowest concentrations were detected in milk sampled 10 days after calving. High concentrations
of IGF-1 observed in colostrum, especially in the 1st colostrum, reflect its potential for eventually
use in the treatment of various intestinal diseases. However, further research should determine
the conditions and limitations of its application. On the other hand, additional research is needed
to determine whether IGF-1 in milk has harmful effects on human health and whether it is
necessary to limit the permitted presence of this hormone in cow milk.

AB  - Season may affect calves thermal comfort and behavior, but the data related to the overall influence of seasonal variations on dams colostrum and postnatal adaptive capability of calves are limited. The aim of this study was to measure the effects of a 49-day-long low air temperature (LAT) season (5.20 +/- 0.46 A degrees C mean air temperature) and a 53-day-long high air temperature (HAT) season (27.40 +/- 0.39 A degrees C mean air temperature) on dams colostrum quality and physiological, biochemical, hormonal, and oxidative stress parameters of their calves during the first 7 days of life. The dams colostrum was sampled at 2, 14, and 26 h after calving, before feeding of their calves. Calves blood samples were taken before the first colostrum intake and on days 1, 2, 3, and 7 of life. Calves physiological parameters were measured on days 0 and 7. HAT season significantly reduced the quality of dams colostrum. The ingestion of the low-quality colostrum, combined with the thermal discomfort during HAT season, probably provoked impaired physiological, biochemical, hormonal, and oxidative stress parameters in samples taken from the post-colostral calves. Additionally, intravenous glucose tolerance test was performed on day 7, which suggested an enhanced insulin response in HAT season calves. This study highlights the importance of adequate supporting strategies for the care of the late gestation cows and postnatal calves during the HAT season.
