whey, ultrafiltrated permeate, liquid protein supplements, steers
A field trial experiment was conducted using 50 steers t o evaluate the feeding value of the ultrafiltrated permeate of whey (UFP) and products made from additional processing of UFP. All steers were fed nutritionally balanced grain mixes and hay. Experimental diets were control (C), in which the grain mix contained primarily corn, oats and soybean meal; UFP fed as the only liquid; partially fermented permeate (PFP), which contained 10% dried yeast added to the ultrafiltrated permeate, fed as the only source of liquid; fermented ammoniated condensed permeate (FACP), which replaced soybean meal in the grain mix; and ammolac (AMM), FACP plus vitamins and minerals. Steers fed C, FACP and AMM diets had free choice access to water. The liquid UFP and PFP were readily consumed by steers and supplied 4.8 l b of dry matter which replaced 5.3 l b of grain. Weight gains, total feed dry matter consumption and feed dry matter per weight gain were similar for steers fed all five diets , indicating that all four of these whey products were utilized as well as more traditional feeds. The quality of carcasses from steers fed the whey products were at least as good as and possibly better than from steers fed the control diet. The feeding of UFP or PFP would likely be the most economical alternative for feeding ultrafiltrated permeate of whey. However, some concentrating of the permeate to increase the solids content from the present 5.0 to 5.5% solids to greater than 10% solids may allow UPF or PFP to replace even more grain.
