Rafael, Johannes, and Andreas W. Herling. Leptin effect in ob/ob mice under thermoneutral conditions depends not necessarily on central satiation. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R790–R795, 2000.— Energy expenditure in ob/ob mice kept at thermoneutrality was quantified from food intake and body composition of mice treated with leptin over 15 and 75 days, respectively....

The objectives of this study were to evaluate heat stress feed intake models for growing swine using a data set assembled from the literature and to develop a series of new equations modeling the influence of the thermal environment and interactions between the thermal environmental and other factors on feed intake. A literature survey was conducted to identify studies assessing intake response...

Managing stressors is essential for optimizing pig growth performance. To determine the effects of temperature and space allocation on growth performance and carcass characteristics, pigs were housed within their thermoneutral zone, at 23.9 degrees C, or above their thermoneutral zone, at 32.2 degrees C, and were provided either 0.66 or 0.93 m(2)/pig for the final 35 d of the grow-finish period...

The objective of this study was to determine if a diet supplemented simultaneously with vitamins C and E would alleviate the negative effects of heat stress, applied between 28 and 42 days of age, on performance, carcass and meat quality traits of broiler chickens. A total of 384 male broiler chickens were assigned to a completely randomized design, with a 2×3 factorial arrangement (diet with o...
