Effect of Levels of Meat and Bone Scraps on Growth Rate and Feed Efficiency of Growing-Finishing Swine

Abstract

Three experiments were conducted with 248 crossbred pigs to determine the effects of level of meat and bone scraps in the ration (2.5 to 10%) on gains and feed efficiency of growing-finishing swine. In all three experiments the negative linear regression of average daily gains on levels of meat and bone scraps was significant. The addition of 0.025% Sucro-Flavor to rations containing meat and bone scraps resulted in greater gains but the increase was not significant. In experiments 2 and 3, feed intake decreased with increasing levels of meat and bone scraps. The linear regression of feed intake on levels of meat and bone scraps was significant. In general, feed required per pound of gain was not appreciably affected by level of meat and bone scraps.
