Chinese pigs are known for their high prolificacy and have been incorporated in breeding programs for nearly 20 years. In overall merit, the Meishan breed has proven superior to other Chinese breeds and was therefore used to produce crosses. Meishan synthetic sows produce larger litters and wean heavier litters than sows from white genotypes. This superiority in lactation performance has been ascribed to better maternal abilities of Meishan sows, when compared to European breeds, with fewer incidents of sows crushing their piglets in the peripartum period and sows allowing a better udder presentation.
To study in more detail on the performance and behaviour of the Large White and Meishan sows and their litters as well as in milk yield and composition, an experiment was carried out at the Dairy and Swine Research and Development Centre from Agriculture and Agri-Food Canada in Quebec.
The article will describe the experimental procedures in detail, as well as presenting the final result and conclusion.
