Shade and water misting effects on behavior, physiology, performance, and carcass traits of heat-stressed feedlot cattle.
One hundred twelve crossbred feedlot heifers were used in two experiments to assess the impact of heat stress and its relief by shade and(or) water misting on behavior, physiology, performance, and carcass traits. Treatments were 1) no shading or misting (CONT); 2) only misting (MIST); 3) only shading (SHADE); and 4) shading plus misting (SHMI). Head in the feed bunk, head in or above the water...
متن کاملSelection to Improve Performance of Cattle in Subtropical Regions Using Heat Tolerance EPD
Subtropical regions such as the South-Eastern United States as well as places like Brazil are characterized by average year round temperatures of 27 ̊C (80°F). In the summer months temperatures can rise to 43°C (110°F). These temperatures are usually associated with high humidity and low forage quality and it is imperative that beef cattle in these regions be able to withstand these warm, harsh ...
متن کاملShade effects on performance, carcass traits, physiology, and behavior of heat-stressed feedlot heifers.
To determine whether shade influences performance, carcass traits, immunology, respiration rate, and behavior of cattle under conditions similar to those in commercial feedlots, we used 168 heifers in 12 soil-surfaced pens. Six pens were shaded with a galvanized steel-roofed shade (approximately 4 m high), allowing for 2.12 m2 of shade/heifer, and six pens served as the unshaded control. Heifer...
متن کاملFEEDLOT MANAGEMENT Matching Cattle Type and Feedlot Performance
Correct projection of breakeven prices is essential to profitable cattle feeding. In order to calculate breakevens correctly, feedlot performance must be predicted accurately. Average daily feed intake (ADFI), average daily gain (ADG), feed conversion (F/G), days on feed, carcass characteristics, morbidity and mortality can vary greatly from one group of cattle to another. This paper will revie...
متن کاملEnvironmental factors influencing heat stress in feedlot cattle.
Data from 3 summer feedlot studies were utilized to determine the environmental factors that influence heat stress in cattle and also to determine wind speed (WSPD; m.s(-1)) and solar radiation (RAD; W.m(-2)) adjustments to the temperature-humidity index (THI). Visual assessments of heat stress, based on panting scores (0 = no panting to 4 = severe panting), were collected from 1400 to 1700. Me...
