Corpora lutea diameter, plasma progesterone concentration and follicular development in PGF2c, 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 PGF2a and CIDR synchronized estrus cycle, their subsequent estrus cycles, and in unsynchronized, naturally cycling Boer x Feral crossbred goats. The PGF20, g...
