Twenty-four barrows were randomly divided into two groups. One group received daily subcutaneous injections of 70 μg porcine somatotropin (pST)/kg body weight (BW) from 40 kg BW until slaughter (108 kg BW). The second group received daily equal volume injections of a sterile bicarbonate buffer, pH 9.4. The left side hams, loins, and bellies obtained conventionally, were processed into typical cured products. Warner-Bratzler shear values, % protein, % fat and visual fat to lean ratio were increased by pST (P<0.05). The treated products had characteristics beneficial to both processors and consumers.
