In order to evaluate heat tolerance, physiological constants of 32 cows were measured (Chinampo: n = 12; Holstein: n = 10; Jersey: n = 10). From June to December 2006, rectal temperature and respiratory rate were recorded every Monday at 0600 and 1700 h. Holstein rectal temperature was affected by heat most, followed by Jersey, and Chinampo (the most heat-resistant). Respiratory rate of the 3 breeds was affected by climatic factors, but the Holstein and Jersey cows registered values higher than those of Chinampo cows. With a temperature-humidity index (THI) above 72 the physiological variables of all 3 breeds increased. …

This study was conducted to determine the effects of different physical modifications (sprinkler and fan) related to heat stress during summer on relevant blood biochemical measures and physiological responses, such as rectal temperature (RT), respiration rate (RR), heart rate (HR), testis temperature (TT), and head temperature (HT), in kids. In total, 32 male German Fawn × Hair kids at 6 months of age were divided into 4 groups of 8. Treatments were as follows: group A: (no sprinkler, no fan) (control); group B: sprinkler only (at 1000-1100 and 1400-1500), no fan; group C: fan (1.5 m/h between 1000-1800), no sprinkler; …
