The Supplementary Value of Choline and Methionine in a Corn and Soybean Oil Meal Chick Ration ,

Condensed Fish Press Water and Fish Liver Meal in Chick Rations ,

“…Whether sardine meal is of value purely as a protein supplement (chiefly as a contributor of methionine) or partly as a vitamin supplement (choline and other vitamins) has not been clearly proved. The relationship of the interchangeable supplementary action between choline and methionine in a chick ration consisting largely of corn and soybean oil meal was discussed by Marvel, Carrick, Roberts, and Hauge (1944). EXPERIMENTAL Five trials were conducted to ascertain the value of fish press water and fish liver meal as supplements to simplified rations composed largely of ground yellow corn and soybean oil meal.…”

Distillers’ Dried Solubles in Chick Rations Containing Corn and Vegetable Protein Supplements ,

“…Feeding experiments were conducted with Barred Plymouth Rock baby chicks confined in chick starting batteries, as previously described by Marvel et al (1944).…”

A Comparison of Soybean Oils and Soybean Oil Meals in Chick Rations Containing Distillers’ Dried Solubles ,

“…The possibility of differences in the availability of the choline in the various meals (Berry el al., 1943b) has not been ruled out. However, the differences in the erowth-promoting values of the soybean oil meals may be due to differences in the availability of the methionine content of the meals, since it has been shown by Marvel et al (1944) that choline and methionine exert an intersupplementary action in a corn and soybean oil meal ration. The action of choline in improving the growth of chicks receiving rations containing soybean oil meals of lower growthpromoting value may be that it supplements the lower level of available methionine in these rations.…”
