Influence of different seasons during late gestation on Holstein cows’ colostrum and postnatal adaptive capability of their calves

Abstract: 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 °C mean air temperature) and a 53-day-long high air temperature (HAT) season (27.40 ± 0.39 °C mean air temperature) on dams' colostrum quality and physiological, biochemical, hormonal, and oxidative str… Show more

“…Therefore, when cows are subjected to heat stress in this stage, subsequent lactation can be affected, which can impact calf health. Heat stress during late gestation has been shown to reduce calf birth weight, which remained significantly reduced at 7 days of age, according to Trifkovi et al [21]. Monteiro et al [22] found that heat stress in the last 6 weeks of pregnancy harmed the ability of calves to acquire passive immunity.…”

“…Warm environmental conditions during late pregnancy reduce colostrum quality. The effects of warm environmental conditions on colostrum quality are associated with several mechanisms including reduced dry matter intake (Das et al 2016) and impaired mammary growth before parturition (Trifkovic et al 2018).…”

“…Prenatal heat stress during late pregnancy alters the immune function of calves (Strong et al 2015). Additionally, Trifkovic et al (2018) reported that, during the summer season, dams and calves had a compromised immunity. The same authors also observed lower blood IgG during the first week of life.…”

“…Furthermore, since it is quite difficult for the immune system to maintain a balance in the HS state, this can negatively affect the safety of the fetus. Trifković et al (2018) found that HS impairs colostrum quality in fresh cows. In combination with thermal discomfort, this caused a violation of physiological, biochemical, hormonal parameters and oxidative stress, which was confirmed by blood samples taken from calves after the completion of drinking.…”
