Effect of water sprinkling on incidence of zoonotic pathogens in feedlot cattle.
Heat stress and dusty conditions are common challenges for cattle during the summer, and a typical method of alleviating these problems involves sprinkling cattle and pens with water. The effect of sprinkling water on the incidence of zoonotic pathogens has not been previously studied. Four pens of heifers (n = 41) were cooled using sprinklers, and four pens (n = 43) served as controls. Heifers...
متن کاملFeeding value of cottonseed meal for feedlot cattle.
One hundred twenty crossbred steers (294 kg, initially) were used in a 141-d finishing trial. Four concentrations (8, 16, 24, and 32% of diet DM) of cottonseed meal (CSM, prepressed solvent-extracted) replaced steam-flaked corn in a corn-based finishing diet. Increasing level of CSM decreased ADG (linear component, P < .10), feed efficiency (linear component, P < .01), and dietary NE (linear co...
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...
متن کاملA new heat load index for feedlot cattle.
The ability to predict the effects of extreme climatic variables on livestock is important in terms of welfare and performance. An index combining temperature and humidity (THI) has been used for more than 4 decades to assess heat stress in cattle. However, the THI does not include important climatic variables such as solar load and wind speed (WS, m/s). Likewise, it does not include management...
متن کاملFat Quality and Feeding Value of Fat for Feedlot Cattle
While much attention has been directed at understanding factors influencing the NE value of supplemental fat (Zinn, 1994), alterations in NE do not necessarily form the basis for constraints on supplementation. Indeed, greater concern is often directed at potential detrimental effects of supplemental fat on diet acceptability and feed intake (Brethour et al., 1957; BuchananSmith et al., 1974; C...
