Effects of Spray-Dried Blood Cells in Lactation Diets on Sow and Litter Performance

Kansas State University Swine Research. High producing sows were used to evaluate the effect of spray-dried blood cells as a dietary protein source on lactation performance and subsequent reproductive performance. No significant differences were observed between sows fed a corn-soybean cells-based diet or a diet containing 2.5% spray-dried blood cells for lactation performance or subsequent reproductive performance. Therefore, spray-dried blood cells can be used as a partial replacement for the protein source in lactation diets.
