Scientific data for carcass traits of terminal-sire sheep breeds can be used to improve the value of market lambs, but information is lacking for modern terminal-sire breeds in the United States.

After a previous 84-d performance phase, a study was conducted using 16 West African Dwarf (WAD) ewes.

The experimental animals were assigned to 4 treatment groups A (O%MSLM), B(15%MSLM), C (30%MSLM) and D (45%MSLM) of 4 ...
