Abstract

The need for improved facilities for beef production is emphasized by the fact that human beef consumption in the United States increased by approximately 56 percent in the 1950's and 1960's. In 1949, approximately 73 pounds of beef and veal per person were consumed, and in 1969, approximately 114 pounds per person were consumed. Demand will keep increasing as people consume more beef and as the population grows. From an economic standpoint, beef is South Dakota's single most important agricultural product with sales producing approximately half of South Dakota's cash receipts from farm marketing. Nationally, South Dakota ranked sixth in number of beef cows and eleventh in number of cows on feed on January 1, 1971. Increased numbers of modern livestock feeding and housing systems must be developed to reduce effects of climatic extremes on livestock if South Dakota is to continue or improve its high ranking of cattle on feed, since predictions are that by 1975 nearly all cattle in the United States will go through a finishing period before slaughter. Therefore, the objectives of this study were established as follows: 1. Determine the total heat and moisture production from a closed confinement beef building under actual production conditions. 1. Numbers in parenthesis refer to literature cited. 2. Determine sensible and latent heat production from a closed confinement beef building. 3. Determine the heat and moisture contributions to the environment from the manure storage tank located under the slotted floor.
