Three experiments with growing rats and two with pigs were carried out to evaluate a vitreous endosperm variety of high-lysine maize and to compare its nutritive value with that of a soft endosperm opaque-2 and a common maize. The results indicate that the vitreous endosperm variety has a signifi...
One experiment was completed with 56 weanling Duroc x Landrace x Yorkshire swine and two with weanling Sprague-Dawley rats to determine the nutritive value of Colombian floury-2 corn in comparison with that of Colombian opaque-2 and Colombian common corn. In both rats and swine Colombian floury-2...
Pigs self-fed diets in which whole cottonseed (including the hulls) replaced one third, two thirds or all the protein supplied by soybean meal gained at a reduced rate and mortality resulted at the highest levels. Iron from ferrous sulfate was ineffective in preventing toxicity because of physica...
Crossbred Duroc × Hampshire-Landrace (D × HL) pigs from 24 litters were assigned at 56 days of age to either a standard corn-soybean meal-type diet containing 16% protein or a similar diet containing 10% protein. Of 66 pigs fed 16% protein (53 females, 13 males), 13 females and three males were c...
Rats fed a corn base diet supplemented with dehulled cottonseed kernels which were boiled in a ferrous sulfate solution for 30 min gained as rapidly and required no more feed per unit of gain than those fed a corn-soybean meal diet. Boiling cottonseed kernels in the absence of ferrous sulfate gre...
