If breeders of animals do not discriminate about which specimens they use to produce the next generation, and indeed go out of their way to medicate the weakest specimens and breed from them as much as from the strongest, then it surely couldn't be more than a couple of generations for the stock to have generally become less fit. And this would continue to happen if the practice of non-discrimination continued.
"The incidence of many of these diseases is doubling or tripling each generation."
Richard Lynn: Dysgenics - a review by Marian Van CourtThroughout our evolution, the weak and diseased died young and didn't pass on their genes. Now, because of modern medicine, people with numerous genetic diseases live long enough to reproduce and transmit defective genes to their children. (Examples: cystic fibrosis, hemophilia, diabetes, pyloric stenosis, various heart defects, thalassemia, phenylketonuria, and sickle cell anemia.) The incidence of many of these disorders is doubling or tripling each generation. No one would deny sufferers treatment, but it's important to realize that, as a result of it, our genetic potential for robust good health is declining. Life-long care will require ever-increasing expenditures. Furthermore, while sufferers are grateful for medical advances, most would nevertheless be quick to point out that the quality of their lives would be far better if they'd never inherited a disease in the first place.
