PREGNANCY
Unobserved Estrum
PERSISTENT CL
MUMMIFIED FETUS
FETAL MACERATION
PYOMETRA
HYDRO/ MUCOMETRA
UTERINE INFECTIONS
PCL-DOES NOT OCCUR IN THE PRESENCE OF NORMAL NON-PREGNANT UTERUS

4. FALSE ANESTRUS -Treatment
PGF2 alpha
Dose
Natural 25mg/ Synthetic g
Single Injection – Palpation CL necessary
Double Injection – Palpation CL not necessary

5. TRUE ANESTRUS SMALL INACTIVE OVARIES
To be confirmed by repeat examination 10 days later
Major Cause
INSUFFICIENT RELEASE OF GONADOTROPINS OR FAILURE OF THE OVARIES TO RESPOND

6. Ovarian

Hormonal Therapy

8. GnRH Induces follicular growth and ovulation within 18 to 23 days Dose
500 g Gonadorelin (FERTAGYL)
8–20 g Buserelin (RECEPTAL)

9. PROGESTERONE Most effective Intravaginal pessaries (CIDR)
Ear implant (Synchromate-B)
Stores LH concentration in pituitary
Mimics natural Progesterone phase
Induces ovulatory estrus in most of the animals
