Effects of ambient temperature on performance and health traits in dairy cattle when considering husbandry factors
Abstract
Prolonged periods of high ambient temperatures, particularly in connection with high humidity, not only affect the farms' production resources but may also have a direct impact on dairy cows. Rising ambient temperatures result in problems with regard to the regulation of the internal body temperature as the cows' ability to dissipate body heat is reduced. In high-yielding cows this is effect is additionally enhanced due to higher metabolic activity. Certain construction and husbandry measures in dairy cattle farms may however alleviate the negative effect of high ambient temperature and humidity. Currently, 168 Austrian dairy farms are analysed with regard to production efficiency (Project Efficient Cow, www.dafne.at, Project No. 100861). By means of detailed questionnaires, e.g. data on feeding or animal health are recorded. Information of an additionally developed questionnaire, including specific construction and husbandry aspects, may be merged with performance data from the central cattle data base. Utilizing data of farms with representative weather records, the effect of ambient temperature on dairy cows' performance and health (and thus on heat stress and welfare) may be analysed considering various husbandry factors.
