Summary

One hundred and twenty-four young rabbits of the Giant of Spain breed (mature weight, 4 to 4·5 kg) were slaughtered in groups at birth, 10, 20, 30, 40, 50 and 60 days of age.

Energy retention over the six 10-day periods was 10·7, 26·5, 39·0, 48·9, 72·6 and 57·3 kcal/day, energy content per unit of weight increase was 5·18, 5·52, 5·52, 5·47, 5·80 and 5·89 kcal/g, and deposition of protein (N×6×25) was 1×45, 3×09, 4×28, 5×56, 7×31 and 5×44 g/day. The regression of the energy content of the empty body (kcal) on empty-body weight (g) was:

Y = 1×734 X – 88·536

with a coefficient of regression of 0·97.
