Indiscriminate breeding - breeding without due care and attention to the conformation, soundness, use and temperament of the parents.
Not the only way for breeding to be bad or unnecessary, of course - breeding for a nonexistent market, without the funds to do it properly, for profit alone, or on the basis of faulty logic (my horse is an awesome sports horse and therefore should pass on his genes, even though he's a quirky little **** to ride and his offspring will probably kill anyone he encounters - but I love him so I can't see that) is all equally flawed.
