Abstract Text:

The impact of the hypermuscularity GDF8 gene on maternal traits  in sheep has been tested following 2 sheep designs, 1 at INRA experimental flock with cross Belgian Texel by Romanov and Romane, 1 at GID Lacaune flocks with introgressed GDF8 mutated sheep. Maternal traits tested were prolificacy, lamb mortality rate from birth up to 60 days of age, ewe suckling ability estimated from lamb 30-days liveweight. Flock-year-season effect has been tested as well as ewe physiological status effect, breed effect, lamb sex and birth or rearing modality together with GDF8 mutation effect.
