In terms of litter size in swine, which breed is known to have the highest litter size ratio?

1. Yorkshire

2. Landrace

3. Berkshire

4. Poland China

The correct answer is: Landrace

The Landrace breed is well-known for having one of the highest litter size ratios among swine breeds. This breed has been specifically developed for its maternal qualities, including fertility and the ability to produce larger litters. Landrace sows are distinguished by their prolificacy and can consistently deliver more piglets compared to other breeds. In practice, the average litter size for Landrace sows can often exceed that of alternative breeds, making them a favored choice for producers aiming for high piglet production. Factors contributing to the high litter size include genetics, reproductive management, and maternal instincts, which allow Landrace sows to nurture and care for larger numbers of piglets effectively. In comparison, while other breeds like Yorkshire are also recognized for good reproductive performance, the Landrace typically surpasses them in terms of litter size. This well-established reproductive ability of Landrace contributes to its reputation and popularity in swine production systems focused on maximizing productivity.
