摘要
The concentration of progesterone in the blood was used to study the effect of body condition score (BCS) on the post-partum ovarian activity of dairy goats. Sixty-eight female goats were distributed between three treatments. Treatment 1: goats with BCS between 1.00 and 2.75; Treatment 2: goats with BCS between 2.75 and 3.50; and Treatment 3: goats with BCS between 3.50 and 5.00. The goats had the blood collected immediately after birth, and from that time up to the eighth week post-partum at three day intervals. The progesterone analysis on the blood was used to determine the interval between the birth and the first ovulation. The females were teasing two times per day for estrus detection and determination of the time interval from birth to first estrus. No significant difference was found on the progesterone concentration between treatments. The luteal functionality was characterized in only 5.9% of goats, with a concentration higher than 1ng/mL. The period from birth to first ovulation was 46 days. The detectable estrus was found in only 4.4% of goats. The BCS at birth did not influence the recovery of ovarian activity of dairy goats.
