Abstract
Studies were conducted on the effects of humidity level (85, 30 or 85-30% alternating) in a warm growing environment (29° C.) on the quantitative and qualitative traits of Landrace carcasses. The rate of gain and composition of the carcasses were not altered markedly by environmental humidity level. Color and gross morphology mean ratings and means of processing properties of the muscles were not significantly different among the treatment groups, although pigs reared in high humidity tended to have superior l. dorsi color and gross morphology. Humidity level in the growing environment influenced the direction of association of quantitative and qualitative carcass traits. The experiment indicated that high (85%) environmental humidity in combination with a warm temperature does not have detrimental effects on the growth, carcass composition and muscle quality of Landrace pigs.
