Performance of rats and swine fed Colombian floury-2, Colombian opaque-2 or normal corn
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 co...

| description | 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 corn (both male and female) was inferior to opaque-2 corn and similar to common corn when daily gain and feed/gain were the criteria of response. In rats, the PER obtained with floury-2 corn was also inferior to that with opaque-2 corn and similar to that with common corn. The floury-2 x opaque-2 cross supported weight gain, feed/gain and PER midway between that supported by floury-2 or opaque-2 corn alone. A comparison of the amino acid requirements of the weanling pig with the amino acid content of the floury-2 corn indicates that lysine and tryptophan and possibly isoleucine and threonine are the limiting amino acids in Colombian floury-2 corn. Further work is needed to determine the identities and proper supplemental levels of amino acids needed to support optimum performance in animals fed Colombian floury-2 corn. |
