breeding program
Fertile? The Bleu du Maine certainly is: an average of 2.20 lamb per pedigree ewe and on the best pedigree breeding farms an average of 2.42 lamb per ewe is even achieved. The ewe can easily suckle the young, partly due to the natural richness of milk. That is also the cause of the actual weight gain between the 10th and 30th day of life of an average of 280 grams per day. Considering the low birth weight of 3.5 – 4 kg, that is not bad. Another (economic) good quality is the longevity of the variety. There are enough breeders who sometimes don't have to replace a single ewe for a year.

In France, the breeding program to improve genetics mainly focuses on the fertility of the ewes. The variation in fertility still deserves a lot of attention. As mentioned, the Bleu du maine has a high milk content. This allows for a greater number of lambs per litter. The variety is suitable for production hybrids (crosses that increase yields) and therefore emphasis is placed on developing the characteristics for meat production.
