Fattening pigs and pigs for breeding have been fed γ-irradiated and non-irradiated control potatoes. The irradiation dose was 14–15 kilorad at the rates 175 r/sec. and 625 r/hr. Rats (Wistar) were also fed irradiated and control potatoes, but in this case the tubers were given a dose of about 200 kilorad. No unfavourable effects have been observed from the feeding with irradiated potatoes. All the facts indicate that the nutritional adequacy of the irradiated and the control tubers is equal. In some cases, the animals have even shown an improvement after feeding on irradiated potatoes which was not apparent after feeding on non-irradiated potatoes; for example there was a more rapid growth, somewhat higher fertility, and increased haemoglobin values. However, current experiments with larger groups of animals will provide more definite evidence in these questions. |
