    abstract = {Follicular and luteal phases of estrus cycle of Tapri and mixed goats under semi intensive
management system. In order to get insight to understand the mechanism of steroidogenesis and study of
various phases of estrus cycle in highly prolific Tapri goats of Sindh, in first phase an attempt was made to
determine the length of various phases of estrus cycle of Tapri breed and its comparison with cross breed goats
during three estrus cycles. Total ten healthy adult cycling goats (five from each breed) were maintained at the
departments of animal reproduction and livestock management, FAHVS, SAU, Tandojam. Vaginal cytology
method was used as marker to determine the status of estrus cycle. It was found that mean length of estrus cycle
in tapri and cross breed goats were 21.32±0.26 and 21.2±0.56 days, respectively, both the longest
(22.2±0.67 days) and shortest (20.4±0.66 days) duration of estrus cycles length were found in cross breed. The
length of follicular phase including the estrus was 1.48±0.07, 1.34±0.01 days and during proestrus period it was
2.98±0.01 and 3.20±0.1 days in tapri breed and cross breed respectively, similarly, during luteal phase the
length of metestrus and diestrus were in tapri versus cross breed goats were 3.25±0.14 vs 3.28±0.6 and
13.59±0.10 vs 13.28±0.4 days, respectively.}
