Corpora lutea diameter, plasma progesterone concentration and follicular development in PGF2α and CIDR estrus synchronized goats.

The current study compares the number and diameter of the corpora lutea (CL),plasma progesterone concentrations and follicular development in PGF2α and CIDR synchronized estrus cycle, their subsequent estrus cycles, and in unsynchronized,naturally cycling Boer x Feral crossbred goats. The PGF2α grou...
