Abstract

Twelve primiparous Egyptian buffalo cows were used in this study during the
period from July 2001 to April 2003 to investigate the post partum anestrus. The
animals had 3.75 years of age with an average weight 435.41± 5.32 kg. The average
length of post-partum anestrus was 62±3.33 days. Buffaloes calved during cold
season (Nov. to April) had longer (7S.2S±7.70 days) post-partum anestrus than those
calved during hot season (May to Oct.) 46.86±4.25 days. Overall mean of
progesterone concentration during the entire length of post-partum anestrus was
0.16±0.29 ng/mL 53.33% of animals exhibited either seasonal or long-term anestrus or both
through the study. Progesterone levels during anestrus (post-partum, seasonal and
long-term) were basal 0.6 to 0.42 ng/ml. The overall lengths of seasonal and long-
term anestrus were 122±5.75 and 48.13±4.42 days, respectively. Progesterone
profiles showed that tow thirds of the animals (66.67%) had post-partum anestrus
continued with either seasonal anestrus or long-term anestrus or both of them along
period of the study. This phenomena is considered to be a serious problem because it
decreased the percentage of buffaloes that hastened their ovarian activity during the
first 40 days after calving.
