Blood and Hormonal Profile Association with the Length of Estrous Cycle in Saanen Etawah Crossbreed Goat

Background and Objective: In mammals the prevalence for short estrous cycle (SEC) was increased which may cause reproductive failures. So the aim of the study was to identify the hormonal and blood metabolite profiles of Saanen-Etawah cross-breed does (SECD) which has a short estrous cycle (SEC) and normal estrous cycle (NEC).

Materials and Methods: The does (n = 32) were divided into 2 groups, according to the length of the estrous cycle: SEC (<17 days) and NEC (17-19 days). Blood drew in each phase of the estrus cycle. All the data were analyzed using one-way ANOVA and Student t-test.

Results: The results showed that there was a significant difference (p<0.05) between albumin, cholesterol and progesterone levels in SECD with SEC and NEC. The albumin and progesterone level in SECD with SEC were significantly lower rather than in SECD with NEC but had higher cholesterol level rather than the SECD with NEC.

Conclusion: In conclusion, there was a significant difference in some blood profile and hormonal between SEC and NEC does.
