Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has revolutionized livestock production throughout the … George Cullimore, a Lleyn breeder from Bath, gave an up-date on projects focusing on breeding for parasite resistance at this year’s online Sheep Breeders Round Table conference. Because the genetics of a pig plays an important role in its performance and meat quality, all pig producers should be familiar with breeding systems for pigs.
