Outline of the reproductive management and outcome of gestations for the three generations of ewes under study throughout three consecutive years (2014–2016). The “Original population” (G0), which included 24 ewes from a commercial flock with chronical neosporosis, lambed three times. The “First generation” (G1) of ewes (n = 14), comprising the congenitally infected lambs born to G0 in 2014, lambed twice. The “Second generation” (G2) of ewes (n = 6 ), comprising the congenitally infected lambs born to G1 in 2015, lambed once.
