Summary

Two balance experiments were conducted in poultry using several pea cultivars varying in trypsin-inhibitor contents. Pea seeds were either untreated or treated. Treatments consisted in autoclaving and steam-pelleting in the first and second experiments respectively. Pea meals were included in diets at 40 % and 47 % levels in experiments 1 and 2, respectively. The remaining part of diets consisted of a maize/soyabean meal mixture. The first experiment was carried out with young chicks (3 weeks) and the second one with young chicks (3 weeks) and adult birds. The apparent digestibility of protein of the basal diet measured in young chick were similar in experiment 1 (81.7 %) and 2 (82.5 %). Pooling data obtained in the young chicks in experiments 1 and 2 revealed no significant correlation between apparent digestibility of protein of untreated peas and trypsin-inhibitor level. In young chicks, increase in apparent digestibility of pea protein induced by treatments was not significantly correlated with decrease in trypsin inhibitor level. In adult cockerels (experiment 2), pelleted peas with low level of trypsin-inhibitor had a higher protein digestibility than pelleted peas with high level of trypsin-inhibitor ; but this was not observed for unpelleted peas. Both experiments tended to show that trypsin-inhibitor activity was not the only factor responsible for the variation in pea protein digestibility in poultry. At least 50 % of the variation in pea protein digestibility observed in poultry remained unexplained.
