REMARKABLE INBREEDING RESULTS
In inbreeding experiments at the Northern Breeding Station (Reasoheath) remarkable fertility has been obtained when the station's inbred brother-sister strain of Leghorns has been crossed with an inbred American strain. Fertility was 96 per and 15 out of the 27 pullets gave 100 per cent fertility. Hatchability was 86 per cent. Yet these Reasejhcath pullets have been inbred, brother-sister,, , for six generation,s t and the American strain lor very much lenger. It provides an indication that the turning point has been reached in the Northern inbreeding experiments; the stage when vigour, which drops to a low point, begins to improve. Hatchability in, the Eng lish birds was 61 per cent, or 15 per cent up on the previous season.
