Effect of feeding strategy on milk intake in kits (n = 15 litters per treatment). Group: reproduction-fattening (RF) = reproduction (Repro) diet from 0 to 25 d and 35 to 42 d, followed by the fattening (Fatt) diet from 25 to 35 d; reproduction-reproduction (RR) = diet Repro from 0 to 42 d; lactation-reproduction (LR) = lactation (Lact) diet from 0 to 25 d, followed by diet Repro from 25 to 42 d. Diet R (11.01 MJ DE/kg, 24.0 g lipids/kg, 161 g starch/kg, and 343 g/kg NDF) was formulated to meet the nutrient needs of reproductive females. Diet Fatt (9.73 MJ DE/kg, 23.0 g lipids/kg, 70 g starch/kg, and 415 g/kg NDF) was formulated to meet the nutrient needs of fattening rabbits. Diet Lact (11.88 MJ DE/kg, 49.0 g lipids/kg, 161 g starch/kg, and 302 g/kg NDF) was also formulated to meet the needs of reproductive females and to increase milk production. Bars within a row with different lowercase letters (a,b) differ (P < 0.05).

Effect of feeding strategy on BW of rabbit kits (n = 748, 770, and 804 for the reproduction-fattening [RF], reproduction-reproduction [RR], and lactation-reproduction [LR] groups, respectively, at 0 d). Group: RF = reproduction (Repro) diet from 0 to 25 and 35 to 42 d, followed by the fattening (Fatt) diet from 25 to 35 d; RR = diet Repro from 0 to 42 d; LR = lactation (Lact) diet from 0 to 25 d, followed by diet Repro from 25 to 42 d. Diet Repro (11.01 MJ DE/kg, 24.0 g lipids/kg, 161 g starch/kg, and 343 g/kg NDF) was formulated to meet the nutrient needs of reproductive females.
