Plasma progesterone concentration during oestrus cycle and pregnancy in Finnsheep and other prolific sheep breeds	1988	3	.pdf	application/pdf	1093	66	66	PP concentrations were determined in Finnsheep (n = 16), Polish Heath (n = 13), Friesian (n = 10), Zelazna (n = 12) and Karakul (n = 14). However, it is still not clear whether there is a possibility to predict the litter size (LS) on the basis of PP concentration either dur- ing oestrus cycle or during pregnancy.	cache/afs-72310.pdf	txt/afs-72310.txt
