Abstract

This study was aimed to evaluate the effect of flushing on the reproductive and body weight change on Abergelle breed does. The study indicated that a mix of 300 or 450 g wheat bran (WB) with 50 g noug seed cake (NSC) flushed per day improved the does’ conception rate (70 to 80%) and kidding rate (70%); while does flushed with low concentrate level (150 g WB plus 50 g NSC) or those not flushed had poor and reduced conception and kidding rate almost by half from the flushed ones. However, the high concentrate level is not strategic to reduce abortion rate. Does flushed with high concentrate level (300 and 450 g WB mix with 50 g NSC) were significantly (p<0.05) better in body weight at kidding (18.52 kg) and postpartum weight (19.48 kg) than does flushed with low concentrate level (16.44 and 17.70 kg, respectively). As the concentrate levels supplementation of their dam increased, birth weight of kids increased (1.73 to 2.36 kg). Therefore, the conception rate, postpartum weight, kid production of Abergelle goat can improve by flushing with 300 g WB and 50 g NSC concentrated feed. However, its effect on the reduction of abortion rate is not promising. Further study is needed on the abortion problem.
