Ovulation Induction by Used Deslorelin Acetate in Goats During Anestrus Season

This study determined the inducing of ovulation in local Iraqi goats induction during seasonal anestrus using deslorelin acetate. This study used twenty-four goats that were out of breeding season between January to July 2023. The average weight of goats was 35±5 kg, and aged 2.5 to 3 years. The goats were divided into 2 groups, each one containing 12 goats, all goats synchronized by vaginal sponges (60mg MAP) for 14 days. The treatment injection withdrawal of sponge. The first group received 0.1 mg of intramuscular deslorelin, and the second group (control) received normal saline. The findings of this research were ten does in the first group showed signs of estrus. The results of this study were induction of estrus 83%, Conception rate 90%, litter size 101%, Gestation length 154±2.16 days, and duration of estrus 29.5±4.5 hours were significantly (p≤0.05) in the treated group, While the control group did not show any reproductive performance. Progesterone concentrations were significant (p≤0.05) in all months in the treatment group compared with goats of control. Ultrasonography detection of pregnancy was 100% in treated group by deslorelin in (30 and 60 days) in comparison with control group. The conclusion of the present study was that the use of deslorelin acetate in local Iraqi goats for induction of fertile estrus and ovulation breeding season was greater rates of successful induction of estrus and ovulation and transabdominal transducer at B mode used in the (30-60 days) of pregnancy goats was accurate for early fetal determine.
