Cattle production plays a significant role in terms of world food production. Nearly 82% of the world's 1.2 billion cattle can be found in developing countries. An increasing demand for meat in developing countries has seen an increase in intensifica

Summer heat provides stressful conditions for Bos taurus feeder cattle; in extreme instances these conditions can be fatal. One management option is to provide shade structures for feedlot animals. This study was conducted during the summer of 2001 t

Heat stress in feedlot cattle can cause decreases in feed intake and growth, and in extreme cases may result in death. Providing shade during hot weather has shown inconsistent results, reducing direct and indirect losses in some areas of the United

A study was designed to investigate the thermoregulatory responses of feeder cattle to both acute and chronic exposures to elevated environmental temperatures. Rectal temperatures (RT) and respiration rate (RR) showed significant differences between

Studies were conducted investigating bioenergetic responses of growing cattle to heat challenges using respiration rate as one of the primary measures. Respiration rate (RR) was measured using monitors designed from commercially available thin-film p

This paper explores the climatology of high temperature-humidity index (THI) values (THI ≥ 84) in the U.S. Central Plains. The THI is derived from the dry bulb and the dewpoint temperatures. High THI values are associated with increased stress amon

Fractal dimension analyses have previously been shown to objectively classify thermoregulatory responses of cattle to non-stressing and stressing thermal environments. This report presents a geometric method for calculating fractal dimensions ( D ) f

Altering the microclimate by providing protection from the environment is one of the most useful tools helping animals cope with climatic conditions. For most feedlot cattle, facilities and management programs do not need to eliminate environmental s
