Special Issue Information

Dear Colleagues,

Improving our understanding of quantitative genetics and implementing scientific findings in practice are both crucial for the successful development of novel breeding programmes or the improvement of existing ones. The proper management of animal genetic resources based on the results of comprehensive and well-designed studies can lead to both higher productivity (efficiency) and can also improve the quality of animal products, animal welfare, health, and longevity. This Special Issue calls for contributions related to a wide range of topics related to genetic evaluation (the estimation of genetic parameters and the prediction of breeding values using different tools and information). Even though the usage of whole-genome markers in genetic evaluation is preferred over the traditional pedigree-based approach, we do not limit contributions to genomic selection. Any novel and scientifically based results that can contribute to the improved management of animal genetic resources in special environmental niches will be considered. Studies that contribute to a better understanding of genotypes based on environment interaction are particularly welcomed. In addition, since the preservation of existing genetic variability is sometimes the main selection goal (local breeds), any interesting finding related to this topic will also be considered for publication.

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. Agriculture is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract
Semen quality traits, including sperm morphology, sperm shape, sperm count, ejaculate volume, low percentage of motile spermatozoa in semen, and motility, play a crucial role in male reproductive efficiency and fertilization success.

Semen quality traits, including sperm morphology, sperm shape, sperm count, ejaculate volume, low percentage of motile spermatozoa in semen, and motility, play a crucial role in male reproductive efficiency and fertilization success. This review article highlighted the impact of genetic polymorphisms in genes on semen quality and fertility traits in mammalians. Single nucleotide polymorphisms (SNPs) in these genes were associated with various sperm abnormalities, such as abnormal sperm flagella morphology, reduced motility, impaired DNA integrity, altered antioxidant status, disrupted sperm head–tail junction, spermatogenesis defects, reduced testicular size, and a range of sperm disorders. This comprehensive review of the available literature offers significant insights into the genetic factors influencing semen quality traits, which can contribute to the development of genetic markers and the enhancement of male fertility through assisted selective breeding programs.
