Two experiments were conducted to determine the effect of pelleting and/or expander processing on the nutritive value of feed when fed to growing and ®nishing pigs. Experiment 1 determined the effects of pelleting and/or expander processing on the apparent nutrient digestibility of the diets. In exp

✦ Synopsis
Abstract
Long‐term application of recombinat porcine somatotropin to pigs induced a decrease in fat deposition and a reduction in percentage fat in backfat and intramuscular fat. The proportion of poly‐unsaturated fatty acids especially of C18:2 increased. Lower thickness and higher water content of backfat influenced the fat quality negatively. Growth of subcutaneous adipose tissue was affected substantially by pST administration with evidence of dose dependency. During withdrawal time until slaughter a marked compensatory fat deposition occurred.
