Abstract
Ninety-one colostrum free piglets (five replicates) were obtained by cesarean section on the 113th day of gestation, placed into individual sterile incubators and fed a fortified milk diet five times daily to 3 weeks of age. Eighty-one piglets were successfully reared to 3 weeks of age for an average survival rate of 89%. Average dietary intakes at 7, 14 and 21 days were 500, 1,125 and 1,465 ml, respectively. Average weight gain for the 3-week period was 4.4 kilograms. Conversions of dry matter to gain ranged from 0.76 to 1.15 for individual replicates. These results indicate that colostrum free piglets can routinely be obtained and reared by this technique and, as such, make excellent models for studying the nutritional requirements of the young pig.
