Extending the potential of evaporative cooling for heat-stress relief.

Factors were analyzed that limit the range of environmental conditions in which stress from heat may be relieved by evaporative cooling in shaded animals. Evaporative cooling reduces air temperature (Ta), but increases humidity. Equations were developed to predict Ta reduction as a function of ambient temperature and humidity and of humidity in cooled air. Predictions indicated that a reduction...

The Effect of Grape Seed Extract and Vitamin C Feed Supplements Carcass Characteristics, Gut Morphology and Ileal Microflora in Broiler Chickens Exposed to Chronic Heat Stress

The effects of dietary supplementation of grape seed extract (GSE) and vitamin C on carcass characteristics, gut morphology and ileal microflora in broiler chickens exposed to chronic heat stress were examined. Experimental diets included a control diet (without additive), 3 levels of GSE (150, 300, 450 mg/kg of diet), and vitamin C (300 mg/kg of diet). Each of the five diets was fed to 5 repli...
