The data recorded were used to calculate
hatchability in relation to the number of fertile
eggs and the percentage of chick of good quality
as a function of number of hatched chicks.
Weights of 1-d-old and 7-d-old chicks were
used to calculate the 1) absolute weight gain
(AG) and 2) relative growth (RG) as
AG = Wt7 − Wt0 (1)
RG = 100 × AG/Wt0 (2)
where Wt0 = weight of 1-d-old chick, and Wt7
= weight of 7-d-old chick.
