Abstract

Various trials will be undertaken to study the bromatological composition, digestibility of the nutrients and the anti-nutritional factors of whole soya processed industrially, by steam, extruded and micronized. The digestibility trails will be carried out by the traditional method of total collection of the excreta, one with factory farmed chickens the other with adult rosters. The third trial will be with roosters, using the SIBBALD (1976) methodology. To verify the effect of the age of the birds on the degree of benefit from the nutrients of whole processed soya, a digestibility trial will be conducted, with the same objective mentioned earlier, to verify the best age to introduce the whole toasted and extruded soya in the feed of factory farmed chickens. To study the replacement of soya chaff with whole toasted and extruded soya three experiments with factory famed chickens and four with commercial laying hens. Trials will take place in the Laboratory to test various treatments for the thermal inactivation of the anti-nutritional factors in soya. Another trial with factory farmed chickens, will be conducted to evaluate the effect of the treatments mentioned on the development of the birds.. (AU)
