A. Glimp, W. P. Deweese, J. D. Kemp, and L. K. Stone There appears to be a trend toward marketing lambs at heavier weights. Retail k merchandisers accept heavier carcasses provided they are meatier. Some experimental data suggests a high positive relationship between weight of lamb and amount of fat. The following experiment was designed to correlate the performance of lambs slaughtered at different weights with the loin eye area, percent fat in the rack, and the fat thickness over the l2th rib. Procedure Seventytwo Hampshiresired wether lambs out of Northwestern crossbred ewes were weaned at approximately 18. 1 (40 lb) kilograms and assigned to groups of 24 lambs each to be slaughtered at live weights of 36. 2, 45.3, and 54. 4 kilograms (80,
