Progesterone concentration levels in the different samples drawn from PG and NPG cows irrespective of the breed.

Breed	No.	Samples tested for progesterone concentration (ng/ml)
		Plasma (LSM ± SE)	Serum I (LSM ± SE)	Serum II (LSM ± SE)
NP Boran	9	0.6 ± 1.89	0.51 ± 1.18	0.49 ± 1.89
NP crossbred	9	0.37 ± 1.89	0.29 ± 1.89	0.27 ± 1.89
PG Boran	11	23.22 ± 1.70	18.95 ± 1.70	13.97 ± 1.70
PG crossbred	11	23.06 ± 1.70	19.49 ± 1.70	17.17 ± 1.70

LSM = least square mean; SE = standard error of the mean. No = number of observations; NPG = non-pregnant; PG = pregnant.
