Semi-intensive fattening of ram-lambs up to 40—45 kg 	1988	6	.pdf	application/pdf	2064	85	59	Index words: Finnsheep, Polish Merino, crossbreeding, fattening, semi-intensive, carcass quality, prolificacy, slaughter value Introduction Studies on two-stage commercial cross- breeding of Polish Merino (PM) using Finn- sheep (F) rams showed (6), in the first stage, that F, ewes had a much higher prolificacy (by about 50 %), but their wool production was lower than that of purebred PM (by 5.5 % clean yield), and F, ram lambs had a lower fattening ability and poorer slaughter value than purebred ram lambs. The positive effect of crossbreeding with F on prolificacy and negative on F, ram lambs slaughter value was also found by other authors (1).	cache/afs-72306.pdf	txt/afs-72306.txt
