Physiological Responses of Cattle to Heat Stress
Pakistan lies in the Warm Climate Zones of the world and is subjected to extended periods of high ambient temperature and relative humidity. The objective of this article is to review the physiologic/adaptive responses of acclimated cattle to heat stress emphasizing its affects on nutrient acquisition and metabolism, acid-base chemistry and hormonal balance of the body. Heat stress invokes a de...
متن کاملGrid Pricing of Fed Cattle
*Assistant Professor and Extension Economist–Management, and Professor and Extension Economist–Livestock and Food Marketing, The Texas A&M System; and Professor and Extension Economist, Kansas State University. Grid prices, or value-based marketing, refers to pricing cattle on an individual animal basis. Prices differ according to the underlying value of the beef and by-products produced from e...
متن کاملReturns to Market Timing and Sorting of Fed Cattle
This research examines the returns to a cattle feeding operation that sorts animals prior to marketing using ultrasound technology. The returns to sorting are between $11 and $25 per head depending on the number of groups the pens in which cattle can be sorted. Sorting faces declining returns. These returns can also be viewed as the costs imposed by institutional constraints that limit co-mingl...
متن کاملPhysiological and digestive effects of Neotyphodium coenophialum-infected tall fescue fed to lambs.
The digestive responses and degradation of ergovaline and production of lysergic acid in the rumen of sheep offered Neotyphodium coenophialum-infected tall fescue straw at 2 ergovaline levels were investigated. Six crossbred wethers (56 +/- 3.0 kg of BW) were used in a randomized crossover design involving 2 treatments, for a total of 6 observations per treatment. The experiment consisted of tw...
متن کاملPhysiological and cellular adaptations of zebu cattle to thermal stress.
During their separate evolution from Bos taurus, zebu cattle (Bos indicus) have acquired genes that confer thermotolerance at the physiological and cellular levels. Cattle from zebu breeds are better able to regulate body temperature in response to heat stress than are cattle from a variety of B. taurus breeds of European origin. Moreover, exposure to elevated temperature has less deleterious e...
