Even when mated with the best stallions do the colts sometimes fall short in performance off the track?
Reason I ask is that Niello, Lohnro's full brother, has just been retired to stud in Australia. Lohnro stood his first season last year.
Just had a look at the produce of his female line and apart from Grosvenor who was a champion NZ sire, the other offerings at stud for at least the last eighty years or so have not been what you would call successful. Yet this is one of the best female families in Oz/NZ.
Even Shadea's first foal by Danehill (Sedaka) who was a "moderate" performer has not even sired one "freak" horse which can happen from time to time.
I looked up the female family record of one of my mares last year and was surprised by the number of fillies produced overall but in a direct line could not find one really good sire going back to the 1920s. Strong family nonetheless.
Is there a basis for my assumption?
