One technology uses bovine somatotropin (bST) produced by recombinant technology (38). Somatotropin [9002-72-6] is a growth hormone. The bST-supplemented cows provide an increase in milk output per cow or an increased feed efficiency. Recombinant bST, also known as recombinant bovine growth hormone (rBGH) is the synthetic analogue of a natural hormone that increases milk production in cows (39). The use of recombinant technology was approved by the FDA in 1993. The Commission of the European Community has recommended that the moratorium on commercial use of BGH be delayed until the year 2000. 

Montgomery et al.67 fed pigs alternately a tryptophan-deficient diet and the same diet supplemented with tryptophan. The deficient diet depressed food intake, caused changes in plasma amino acid pattern, increased plasma glucose levels, and increased plasma urea levels per unit food intake. Plasma levels of insulin and growth hormone were somewhat elevated after 2 days of feeding the deficient diet. 

Effects of ID in adult rats Feeding adult rats a diet with a low iodine content (LID) (0.02-0.06 pg I / g) results in undetectable circulating T4 levels, increased TSH and unaltered T3 concentrations, the same changes described for inhabitants of areas with severe ID. T4 decreases in all tissues studied so far (liver, brain, heart, and skeletal muscle) to the same degree as in plasma In contrast, T3 does not remain normal in tissues, as it does in plasma. T3 levels decrease, although not as markedly as T4 T3 in nuclei from liver and brain decrease 2- 2.5-fold with respect to nuclear T3 in rats on the I-supplemented LID (LID+I) All biological end-points of thyroid hormone action... 

Consequently, the workshop recommends specific monitoring of iodine intake of mothers and infants in Europe by periodic analysis of urinary iodine levels, and to the extent feasible, of serum TSH and thyroid hormone measures. The daily intake of iodine should be at least 200 pg in pregnant and lactating women and 90-120 pg in young infants. To reach these objectives, the mothers diet should be systematically supplemented with iodine whenever necessary, by vitamins/minerals tablets as prescribed by physicians. Breast milk is the best source of iodine for the infant, and exclusive breast feeding for 4-6 months should be encouraged. However, when circumstances require that infants receive formula, the iodine content of formula milk should be increased fiom the traditional recommendation of S pg/dl milk to 10 pg/dl for full term and 20 pg/dl for premature babies.
