All the diets were pelleted, stored in darkness to avoid auto-oxidation
of the lipid sources and offered ad libitum.
Individual body weights and feed intakes were recorded on a fortnightly
basis during the experimental period, except for the last period,
which lasted 8 days. The average feed consumption of each rabbit
was used to calculate the individual feed/gain ratio. The performance
and apparent digestibility have been previously reported (Peiretti,
Gai, Rotolo, & Gasco, 2012).
