Summary Fewer Hb A and AB lambs were born than expected in the investigated Hungarian Merino population but the factors responsible for these differences could not be identified. The Hb A and AB breeding ewes were not inferior to their B type herd mates with respect to average daily weight gain (when lambs), reproductive performance (prolificacy) and survival rate. Their reproductive performance was, in some cases, even better than that of the ewes with other haemoglobin types. The haemoglobin types cannot be used as markers when selecting for higher prolificacy.
