[QUOTE="Ebenezer, post: 1725545, member: 24565"] You can also want to avoid a sire or herd that has been linebred if the breeder merely was blind to the obvious or is unscrupulous. I know that the cow has more influence that the sire on a calf. Gestational programming is one thing that the sire can never contribute. Mitochondrial DNA is something that the sire can never contribute to a calf. The environment of the cow can also cause epigenetic triggers to turn on and turn off genes. Cow behavior can do the same. The 50/50 replies do not hold water anymore. But a sorry sire can still wreck your herd. [/QUOTE]
