Early Pregnancy Diagnosis and Fetometry by Real Time Ultrasonography in Teddy Goat.

The main objective of present study was to estimate gestational age of teddy goat by B-mode ultrasound measurement of embryonic or fetal parts and uterine diameter throughout pregnancy by transrectal approach. Three parameters crown rump length (CRL), trunk diameter (TD), and uterine diameter (UD) were selected for measurement of gestational age with the weekly interval from 3rd week to 15 weeks of gestation of 12 pregnant teddy goats, all three parameters were significantly (P<0.01) corelated with gestational age. The CRL was strongly positively correlated with gestational age (r2=0.98) followed by the TD (r2=0.98) and the UD (r2=0.97). The fetal numbers were estimated 19 (five single and seven twines) by transrectal approach in twelve pregnant teddy goats. The earliest day of pregnancy diagnosis was 19 day after mating, while trunk was best parameter for determination of gestational age throughout gestational period and fetal sexing can be diagnosed at 7^th week of gestation period in teddy goats.
