Special Issue Information

Dear Colleagues,

Food security is a major concern associated with an ever increasing world population. Additionally, with the increasing affluence of developing countries, the demand for animal protein is growing. To meet this increasing demand requires more efficient animal production. Pork provides a major contribution to food production globally, but particularly in Asia. In attempts to increase pork production efficiency, there has been significant selection pressure applied to the production of larger litters. Undoubtedly, the resulting (hyper) prolific sows do deliver larger litters, but at a possible welfare cost to sows and piglets.

With a focus on prolific sows, we invite reviews and original research papers that address sustainable biological and economic improvement of sow reproductive performance, particularly if they also target animal welfare. This includes, but is not limited to, sow and litter management and economic considerations.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

The rearing of large litters from hyperprolific sows is a characteristic of modern genotypes. However, these sows have body and reproductive characteristics that differentiate them from the genotypes of the past decades, making it necessary to adopt different management strategies. This review describes the main care and challenges associated with the hyperprolificity of sows during the period in which replacement gilts are selected, along with gestation, parturition, lactation, and the weaning-estrus interval. It describes the challenges that these sows’ piglets will face during the lactation period and includes some strategies adopted to develop these surplus piglets. In addition, it identifies areas where more research is needed to understand the reproductive management of modern genotypes. Full article
