| Abstract | ||
| This study was performed on 45 lactating Holstein -Friesian cows suffered from inactive ovaries for three months postpartum and diagnosed clinically by rectal palpation in the farm of college of agriculture / university of Baghdad, their ages 3-5 years during the period from 2010-2012. These cows were divided randomly in to four groups ,1st group (12 cows) were injected with 0.021mg (5ml) Receptal® I/M, 2nd group(12cows) were given 1000 IU(5ml) eCG I/M ,3rd group (12 cows) injected with 1500 IU (5ml) HCG I/M in one dose and 4th group (9 cows) without treatment (control group). The response rate was 91.8%, 83.3%, 91.6%, and 66.6% for the four groups respectively. While the duration of response (from treatment to estrus appearance) was 7.43±1.56, 10.66±2.37, 8.44±2.41and 67.63%±9.87 in the 1st, 2nd ,3rd, and 4th groups respectively, but the pregnancy rate recorded 90.9%, 80%, 81.8%, 83.3%. The statistical analysis showed that the 1st and 3rd group was recorded significant differences higher (p< 0.01) than other groups (2nd and 4th) related with responsive animal and the duration of response also, but the pregnancy rate recorded higher significance in 1st group ( p < 0.01) compared with 2nd , 3rd and 4th groups. The number of services/ conception was more than 1.5- 2.5 for all groups & not significant, the days open recorded higher significant (p<0.01) in 1st. 2nd and 3rd compared with 4th group (control group). | ||
