Sequence in Which Essential Amino Acids Become Limiting for Growth of Chicks Fed Rations Containing Cottonseed Meal

LIMITED amounts of meal prepared from glanded cottonseed are used in poultry rations. It has generally been recognized, however, that the protein in that meal is too deficient in lysine for large amounts to be included in commercial broiler rations. Grau (1946) found that lysine is the most limiting amino acid in cottonseed meal protein; additional methionine was also needed to allow the most rapid growth rate. Further supplementation with threonine or tryptophan did not increase growth rate. Jonston and Watts (1964) have reported that lysine and methionine are also limiting in meals prepared from glandless cottonseed. Lysine was found to be more limiting in the glanded than in the glandless meal.This paper reports the results of experiments conducted to determine the sequence in which the essential amino acids become limiting for growth of chicks in semi-purified rations based on five different cottonseed meals. The experiments are similar to …

Solubility of cottonseed proteins in hydrochloric acid

The correlations between the growth response of chicks to the nine cottonseed meals fed as a protein supplement and the solvent powers of 0.02N NaOH, 6N HCl, and 0.5N NaCl for cottonseed meal proteins are almost identical. The correlations between the solvent power of 6N HCl, 0.02N NaOH, and 0.5N NaCl and the gossypol contents of the meals are not as good as the correlations between the solvent powers of these solutions and the growth response of chicks.

Evaluating Cottonseed Meal Protein for Chick Growth by Enzymatic Release of Amino Acids

IN A previous study by Ingram, Riesen, Cravens and Elvehjem (1949) it was found that a good measure of the biological value of the protein of soybean oil meal for chick growth could be obtained by subjecting the meal to enzymatic hydrolysis and then measuring the amounts of certain amino acids that were liberated in a given period of time. The soybean oil meal samples were first subjected to acid hydrolysis and the amino acid content determined microbiologically. After enzymatic hydrolysis similar determinations were carried out and the percentage of the amino acids liberated by the enzymes calculated. Good correlation was found between these values and the growth supported by the same soybean meal samples in chicks.The studies reported here were undertaken to determine if this in vitro technique would also accurately measure the relative biological value of different cottonseed meal samples.
