“…Poor nutrition leads to reduced conception, embryonic losses, reduced lambing rates and high ewe mortality (Yoder et al, 1990). Steaming-up gave signifi cantly ( p < 0.01) heavier lambs and litter weight at birth, as reported for other breeds by Reese et al (1990) and El-Hag et al (1995).…”

“…The increased growth in supplemented ewe lambs was refl ected in early puberty and higher reproductive performance. Body weight, rather than age, is the most important factor determining puberty, and well-fed heavier animals conceive earlier than lightweight ones (El-Hag et al 1995;Choque et al 1996).…”

“…Al‐Merestani et al (unpublished data) found that fecundity was significantly increased in untreated Damascus goats from 178 to 217% in MAP‐ and PMSG‐treated does. Fecundity rate in untreated Damascus goats was 155% in Oman (El‐Hag et al 1995), 167% in Egypt (Peters and Laes Fettaback 1995) and 168% in Cyprus (Constantinou 1981).…”

Seventy-five female Damascus goats aged between 1.5 and 5.5 years were used to evaluate the effectiveness of the intravaginal sponges and prostaglandin analogue on oestrous synchronization and fecundity; to diagnose pregnancy and to monitor the resumption of the luteal activity. Females were divided randomly, during the breeding season, into three equal groups, S, P and C. Females in group S were fitted with sponges containing 45 mg of flugestone acetate (FGA) for 14 days and injected with pregnant mare serum gonadotrophin (PMSG) at the sponge withdrawal. Females in group P were given two injections of prostaglandin F2alpha analogue at 11-day intervals, whereas females in group C (control) received no treatment. The results showed that there was a significant difference (p < 0.001) in oestrous exhibition between females in group S as compared with those in groups P and C, with means being 30 +/- 10, 172 +/- 115 and 217 +/- 75 h for groups S, P and C, respectively. Kidding rates resulting from the first and all matings were 80 and 88, 52 and 88, and 68 and 80% for groups S, P and C, respectively. Fecundity rates were 215, 175 and 180% for groups S, P and C, respectively, with a significant difference (p < 0.05) between the S and both P and C groups. Using an ultrasound pregnancy detector performed on days 57 +/- 3 after mating, positive pregnancy diagnosis was 93.3% and 100% for non-pregnancy. Females in the control group showed functional corpus luteum starting in September. It is concluded that FGA sponges plus PMSG treatment could be successfully used to synchronize oestrus and improve fecundity; whereas prostaglandin treatment was not effective to synchronize oestrus. It is also concluded that pregnancy can be diagnosed accurately and successfully using an ultrasound pregnancy detector. In addition, ovarian activity in the Damascus goat in Syria resumes in September.
