“…Our findings were agreed those recorded by some researchers [12] who found that the pregnancy rate was 75% in all groups treated with eCG / hCG. In addition, our findings were consistent with findings of other researchers.…”

HIS study was performed to compare the ability of GnRH alone and combination of PMSG-hCG hormones to induce of estrus in anestrus female dogs (bitches). Hence, a total of 17 local dogs; 15 bitches of 2-4 years old and 2 fertile males (2-5) years old, were selected, prepared and inseminated naturally from December 2022 to June 2023. Firstly, all bitches were divided into three groups; G1 that represents the control and leaves without treatment, G2 that received GnRH at a dose of 0.0042 mg/animal I.M for two days, and G3 that received PMSG at a dose of 40 IU/animal for 7 days and then hCG at a dose of 150 IU/animal on the 8 th day I.M. During anestrus, the vaginal smears showed that the predominant cells were parabasal and small intermediate cells; while in estrus phase, superficial cells were the most common. Ultrasound examination for 10 treated bitches in G2 and G3 groups was made during the 19 th , 30 th , 47 th and 59 th days post mating. Furthermore, pregnancy rate was recorded 80% in G2 (GnRH) group and 75% in G3 group (PMSG / hCG). While, insignificant variation ( P<0.05) was seen in gestational period between G2 and G3. In conclusion, induction of estrus by using GnRH or PMSG with hCG is safe and effective.

The current study evaluated the efficiency of melatonin implants as a single subcutaneous dose to suppress or delay the estrus cycle in queens. Ten domesticated non-pregnant cats of known origin aged between 1-3 years were used. The cats were divided randomly into two groups. The first group (G1, n=5) was left without treatment and served as control group, and the second group (G2, n=5) was administered 18 mg melatonin implants as a single-dose subcutaneously. Before starting treatment at day zero, 3 ml of blood was collected from the jugular vein in all cats to measure estrogen and progesterone hormones. Post-treatment, the cats were monitored twice a day to determine the sexual behavior of estrus based on clinical signs, using a male detector and taking a swab from the vagina to confirm the estrus phase. Also, on days 14, 30 and 60 after treatment, reproductive hormones (estrogen and progesterone) were analyzed in the blood. The results of the current study revealed that interestrus days were significantly higher in the G2 group (111.00 ± 2.68 days) compared to the G1 group (28.00 ± 8.38 days), with a significant difference (P < 0.05). While there was a non-significant effect on estrus duration, with only a numerical increase (P > 0.05) in the estrus phase in G2 (9.20 ± 1.11 days) compared to the G1 group (7.00 ± 0.70 days). The estrogen and progesterone hormone levels were found varied in different periods, however they were remained at basal level (under 20 pg/ml and 2ng/ml respectively) in both groups. In conclusion, the melatonin implant suppresses the estrus cycle for 4 months without any adverse effects and maintains the concentration of estrogen E2 and progesterone hormones at the basal level.
