Abstract
. The effects of heat stress on the concentration of 70 kDa heat shock protein (HSP70) in plasma and saliva, plasma insulin concentration and some metabolic indices (plasma glucose, free fatty acids, beta-hydroxybutyrate and urea concentrations) were assessed in Holstein-Friesian, Hungarian Simmental and Jersey cows. The study included 30 animals from a farm breeding Holstein-Friesians, 30 from a Jersey farm and 30 from a farm keeping Simmentals (10 dry cows, 10 mid-lactating and 10 lactating cows from each farm, respectively). Sampling was performed under thermoneutral (spring) and heat stress (summer) conditions. Based on plasma HSP70 and insulin concentrations, Holstein cows were determined to be most susceptible to heat stress. No characteristic breed-related changes in metabolic indices were found. The results indicated the importance of heat load-reducing strategies in the Holstein-Friesian breed.
期刊介绍：
Journal of Animal and Feed Sciences (JAFS, J. Anim. Feed Sci.) has been published by the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences in Jabłonna (Poland) since 1991. It is a continuation of the Polish-language journal Roczniki Nauk Rolniczych. Seria B, Zootechniczna published by the Polish Academy of Sciences since 1969.
JAFS is an international scientific journal published quarterly, about 40 papers per year including original papers, short communications and occasionally reviews. All papers are peer-reviewed and related to basic and applied researches in the field of animal breeding and genetics, physiology of nutrition, animal feeding, feed technology and food preservation. The journal distinguishes the multidisciplinary nature of physiological and nutritional sciences and so includes papers specialized in all fields connected with animal well-being, including molecular and cell biology and the emerging area of genetics.
