11 wrz 2024 · After calving, all cows were transitioned to an early FRESH lactation diet up to 21 DIM, with an average feed intake of 24 kg dry matter intake (DMI), and 35 kg milk yield.
26 cze 2015 · Heat stress in cattle reduces feed intake, growth, milk production and reproductive potential; increases susceptibility to diseases and in extreme cases causes death resulting in substantial...
1 gru 2023 · Heat loss mechanisms gets activated when cows encounter heat stress, the body increases peripheral blood flow in an attempt to enhance heat loss through conduction and convection (Choshniak et al., 1982). Cows try to minimize solar heat gain by altering their posture/orientation.
25 kwi 2021 · This review presents an updated approach to the physiological and thermoregulatory responses of cattle under various environmental conditions. Strategies for mitigating the harmful effects of heat stress on livestock are suggested as viable alternatives for the betterment of production systems.
5 mar 2020 · Recent studies provide solid evidence that dry period heat stress has significant negative effects on innate and adaptive immune function of both the dam and the offspring, influencing the morbidity and mortality of early lactation cows and calves from birth to first calving.
10 sie 2020 · The current review is designed with aims to highlight the impact of heat stress (HS) on calves and heifers and to suggest methods for HS alleviation. HS occurs in animals when heat gain from environment and metabolism surpasses heat loss by radiation, convection, evaporation and conduction.
24 paź 2021 · Monitoring individual animal response and mitigation strategies for isolated heat-susceptible cattle could save on heat management costs whilst improving animal welfare and productivity. Here we review the technologies that enable automatic, continuous, and real-time cattle heat stress monitoring and mitigation under commercial conditions.
