Two digestibility trials were set to determine digestibility of maize meal by sheep. In the first trial animals were fed hay alone and the following results were obtained.

1. Average hay intake was 1.15 kg of 800g/kg dry matter.
2. Average faecal output was 1.15 kg of 350 g/kg dry matter

In the second trial , 60% of the hay dry matter intake was substituted with maize meal and feeded the sheep again. The average faecal output was 550 kg of 400g/kg dry matter.

1. What was the apparent digestibility of the hay in the first trial?
2. Assuming digestibility of hay remained the same in the second trial . Compare the apparent dry matter digestibility of maize meal  by the sheep.
