Effects of iodine level on performance and thyroid traits of growing pigs.

Four experiments involving 163 pigs were conducted to determine the effects of iodine level in a corn-soybean meal diet on body weight gain, feed required per unit gain and thyroid status. Pigs fed the basal diet (.055 ppm iodine) with no supplemental iodine had lower plasma protein-bound-iodine levels, hypertrophied thyroids and trapped a greater amount of… CONTINUE READING
