The objective of this experiment was to evaluate the effect of body condition score (BCS) and short-term supplementation with high levels of energy and protein sources on the reproductive performance of 180 does consisting of 90 Spanish and 90 Spanish x Boer (60 ½ Boer = F1-cross; and 30 ¾ Boer = F2-cross) genotypes. Each of the 3 genotypes was equally distributed to treatments of 2 body condition groups (BCG, low and high) and 3 flushing treatments consisting of no supplementation (control), supplementation with protein mixture (PM) alone and PM + ground corn (PE) in a 2 x 3 x 3 factorial arrangement of treatments. The flushing period lasted 11 days, after which does were exposed to sexually active Boer bucks for 42 days. The results indicated that although not significant, flushing with PM and PE diets numerically increased the body weight and body condition score of all genotypes in high BCG. In low BCG, flushing with PM and PE diets significantly (
