Publikováno v: International Journal of Biometeorology. 52:725-732

Six Angus steers (319 ± 8.5 kg) were assigned to one of two groups (hot or cold exposure) of three steers each, and placed into two environmental chambers initially maintained at 16.5–18.8°C air temperature (T a). Cold chamber T a was lowered to

Studies of fescue toxicosis using whole seed diets show reduced feed intake and thermoregulatory ability, but much of the seed passes undigested through the animal. Cattle were fed ground tall fescue seed at different levels to potentially facilitate

Two Bos taurus breeds with known differences in heat tolerance were tested under controlled conditions to evaluate heat tolerance. Romosinuano (Romo) is a tropically adapted breed. Nine Angus (304 ± 7 Kg BW) and nine RO (285 ± 7.5 Kg BW) steers fro

Impact of Dehydration on Production and Thermoregulation of Angus Steers at Thermoneutrality

Autor: Tim J. Evans, B Scharf, L E Wax, Donald E. Spiers

Publikováno v: Livestock Environment VIII, 31 August - 4 September 2008, Iguassu Falls, Brazil.

It is known that ruminants undergo various physiological adaptations to cope with dehydration. Since the physiological mechanisms which enable ruminants to deal with water scarcity are only partly understood, a study was conducted to determine if deh
