Abstract
An experiment has been carried-out on physiological responses in Saanen, Anglo Nubian and Toggenburg goats at different body weights and feed intakes during treadmill exercise at 30째C environmental temperature (ET). The results showed that respiration rate (RR) was significant between time 횞 breed interaction (p < 0.01), with values for the Anglo Nubian being least, while the Saanen was intermediate. With time, RR differed significantly, and after 1 h the respective RR were 238, 221 and 303/min in the Saanen, Anglo Nubian and Toggenburg. With time the rectal temperature (Tr) increased gradually and ater 1 h exercise mean values were 40.8, 41.3 and 40.7째C in the Saanen, Anglo Nubian and Toggenburg respectively. Rump skin temperature (RTs) values differed significantly between Anglo Nubians and Toggenburgs, with the differences averaging 0.3, 0.6, 0.4 and 0.4째C after 15, 30, 45 and 60 min exercise respectively. With breed, highest loin skin temperature (LTs) values were in the Anglo Nubian, with an overall mean of 37.9째C (p < 0.05).
