Repeat Breeder Syndrome in ruminant is a great problem which causes considerable amount of production loss.

1. Repeat Breeder Syndrome
Presented by
ABU ZUBAYER TANZIN
ROLL: 14/27
GROUP: B

2. Definition
A repeat breeder cow is defined as one
That has been bred 3 or more times but not
conceived
Has normal estrous cycle
Is free from palpable abnormalities
Has no abnormal vaginal discharge
Is less than 10 years old

3. Etiology
• Fertilization failure
• Early embryonic death

4. Fertilization Failure
• Account for about 15 percent of reproductive
wastage in normal cows
• In repeat breeder cows. The fertilization failure
may be higher around 28-44 percent

5. Causes
AI factors
Anatomical defect
Other factors:
Subclinical endometritis
Delayed ovulation
Insufficient cuprous luteum function
Weak embryos

6. • Ovo-bursal adhesion
• Blockage of the uterine tube

7. AI Factors
• Poor quality semen
• Incorrect timing of insemination
• Incorrect place of insemination

8. Anatomical Defects
Double cervix
White heifer disease

9. Anatomical Defects
Deformities after cesarean section
Aberration of the bursa
Blockage of the oviduct
Deformities of uterus

10. Sub-Clinical Endometritis
Non detected endometritis is a common case
℞
Intra-uterine antibiotic therapy day after
insemination.
10 lakh IU penicillin or 1 gm streoptopenicillin
should be dissolved in 20-30 ml of distilled water
Pre AI treatment should be given 5-6 hours before
AI while post AI treatment should be given 3-6
hours after AI
Parental antibiotic(streptopenicillin 2.5gm)
should be given on day 4 and day 10

11. Delayed Ovulation
℞
GnRH injection at the beginning/ during
estrous or at the time of AI

12. Insufficient Corpous Luteum
Function
Insufficient progesteron production or early
regression of corpous luteum will cause early
embryonic death and return to oestrus
℞
Injection of GnRH at the time of estrous/ AI
treatment with progesteron
implant(norgesteron 3mg, crester) 4 days after
AI. And is to be removed after 12 days

13. Early Embryonic Death
• Account for 25% of reproductive wastage
• Major portion of embryonic death occurs
between day 8 and 16 after breeding
• Most of the embryo death occurs before the
critical stage of pregnancy recognition and the
cow will return to estrous at the normal 18-25
days interval.

14. External factors: Stress like pain and long
transportation etc
Malnutrition: season and climate like summer
Maternal factors
Progesteron deficiency
Uterine infection
Embryonic factors like chromosomal
abnormalities
Genetic factor

15. Weak Embryo
Cannot exert recognition signal in due time
℞
Injection of GnRH at 12-14 days of
insemination

16. Conclusion
• Control of uterine infection
• Correct negative energy balance
• Correct timing of AI
• Assure quality semen
