Two experimental isonitrogenous weaning diets (SBM diet and WLS diet) were formulated. The SBM diet contained soybean meal (70 g/kg) as the main CP source, whereas the WLS diet was based on white lupin seeds (105 g/kg). A total of 160 Hyplus rabbits (33 days of age) were divided into 4 groups according to diet and feeding technique (ad libitum SBM, restriction SBM, ad libitum WLS and restriction WLS group of rabbits). The feeding programme was applied as follows: both the AL SBM rabbits and AL WLS rabbits were fed ad libitum during the whole fattening period, whereas the R SBM and R WLS rabbits had a limited feed intake between 33rd and 47th day after weaning (75% of ad libitum intake). Afterwards, all restricted rabbits were fed ad libitum until the end of fattening period (75 days of age). No significant interaction between dietary CP source and feeding technique was observed in terms of the growth performance of rabbits, whereas the highest hot carcass weight was observed in AL WLS rabbits. Results confirmed that the weaning diet based on WLS fed ad libitum for the whole fattening period is safer than the weaning diet containing SBM in terms of the digestive health of weaned rabbits. Feed restriction had no favourable effect on rabbit health in the entire trial, regardless of the CP source.
