AB  - The aim of current study is to compare fertility rate improvement 
  by using Controlled Internal Drug Release (CIDR) or GnRH (Gonadorelin) in repeat 
  breeder cows. A total of 150 repeat breeder cows with healthy genital tract 
  in clinical examinations were selected and divided into 3 groups of 50 cows 
  group<sup>-1</sup>. In group 1, CIDR is used in day 5 until 12 after insemination. 
  In group 2, an injection of Gonadorelin was done in day 11 after insemination 
  for each cow and group 3 (control), received no treatment. The results showed 
  fertility rate of 28, 16 and 12% in group 1, 2 and 3, respectively. There were 
  significant differences in fertility rate between group 1 and 3 (p = 0.0092) 
  and group 1 and 2 (p = 0.04). In conclusion, the use of CIDR is more efficient 
  than single dose of Gonadorelin in treatment of repeat breeder cows.
