Amino Acid Balance

Chicks fed diets containing 26% of protein had larger thyroid glands than did chicks fed diets containing 17.5% of protein. Thyroidal uptake of I131 per chick was also greater in the chicks fed the higher level of protein. The basal diets were deficient in methionine. Supplementation of the diets with lysine, which would aggravate the amino acid imbalance, significantly depressed thyroidal uptake of I131 per chick. It is concluded that the amino acid composition of dietary protein, as well as the protein level in the diet, affects thyroid activity in the chick.

Protein Output

Effects of dietary protein concentration on the amino acid composition of sow's milk was studied using 10 crossbred first-litter sows. At parturition, diets containing similar concentrations of digestible energy but with either 63 or 238 g crude protein per kg and 4.4 and 15.1 g lysine per kg respectively, were given through lactation (five sows per treatment). The ratios of other amino acids to lysine were in excess of those currently recommended for lactating sows. Dietary protein level significantly affected milk yield, gave higher milk protein output (P> 0.05) but was without significant effect on the proportions of amino acids in the milk.
