Abstract
 
       This study aimed to evaluate two regimens for oestrus synchronization in Baladi goats during the breeding season in Egypt. Total of 41 Baladi does were divided into three groups: group 1 (control) does were considered as control, group 2 (G2) does were treated with 2 injection of PGF2α 11 days apart, and group 3 (G3) does were treated with daily injection with 25 ml progesterone/doe/day for successive 11 days, and one day before the end of progesterone, with a single dose of 500 I.U. PMSG. Results show that percentage of does exhibited oestrus was 78.57% and 92.85% in G2 and G3, respectively. Onset of oestrus was longer in G3 than in G2 (46.7 vs. 52.2 hr, respectively) Estrus duration was longer (P<0.05) in G3 than in G2 (31.9 vs. 23.5 hr, respectively). Kidding rate was higher (P<0.05) in G3 (85.71%) than in G2 (57.14%) and moderate in the control group (76.92%). Gestation period length was shorter in G3 than G2 and control group (144.6, 147.3 and 147.3 day, respectively). Number of kids born per doe was higher (P<0.05) in G3 than in G2 or control one (2.58, 2.00 and 2.20, respectively).
            In conclusion, injection of PGF2α at 11 days interval during diestrus in does resulted in lower response to oestrus and fertility rate compared with those injected with progesterone + PMSG which give higher response to oestrus kidding rate and litter size.
