| Abstract | ||
| This study was conducted on thirty four cows and twenty five buffaloes aged between 3.5- 7 years old in Abu-grab and White gold village at Baghdad suburban. Clinical diagnosis of inactive ovaries was performed by rectal palpation and accomplished by a history of anestrum for at least 3 months postpartum. The cows and buffaloes were randomly divided into 4 groups and treated as follows, G1: 12 cow and 7 buffaloes injected with 1000 I.U eCG (Folligon, Intervet) I.M, G2: 7 cows and 5 buffaloes injected with o.5 mg GnRH analogue I.M (Fertagyl, Intervet). G3: 8 cows and 7 buffaloes injected with 1000 I.U. eCG and o.5 mg GnRH analogue I.M. , G4 : 7 cows and 6 buffaloes injected with 1000 I.U. eCG I.M. and 1500 I.U. hCG (Chorulon, Intervet) I.M. All the treated animals were left free with males to ensure mating. Results of cows responded to various treatments and showed signs of estrus were 9/12 (75%), 3/7 (42.85%), 7/8 (87.5%), and 6/7 (85.71) in G1, G2, G3, and G4 respectively, While the durations of response were 4.12 ±2.1 days, 6.48±2.9 days, 4.89 ±2.8 days and 4.11 ±2.6 days in the same sequence of groups. The number of cows which subsequently became pregnant were G1: 5/9 (55.55%), G2: 1/3 (33.33%), G3: 4/7 (57.14%) and G4: 3/6 (50%). While the number of buffaloes responded to the same treatments and showed signs of estrus were 5/7 (71.42%), 2/5 (40%), 6/7 (85.71%), and 5/6 (83.33%) in G1, G2, G3, and G4 respectively. The durations of response were 4.66 ±2.25 days, 6.1 ±2.82 days, 3.92±1.9 days and 3.5±1.3 days. The number of buffaloes which subsequently became pregnant were G1: 3/5 (60%), G2: ½ (50%), G3: 3/6 (50%), G4: 3/5(60%). It was concluded that the use of GnRH alone gave a significantly lower effect in treating cases of inactive ovaries and also the use of GnRH or hCG with eCG as a combination did not give an additional improvement in results of treating the same cases in both types of animals | ||
