Special Issue Information

Dear Colleagues,

It is estimated that 70% more food has to be produced without destroying the environment by 2050, due to the world's expected nine-billion-strong population. Livestock production contributes 40% of the global value of agricultural output and constitutes a very important component of the agricultural economy, while efficient livestock production requires the selection and development of breeds that are well adapted to the specific production environments, to perform sustainable farming and to maintain economic stability. The animal breeding industry, aiming to improve the quantity and quality of livestock production, has been greatly revolutionized by the adoption of Best Linear Unbiased Prediction (BLUP) and the Genomic Selection (GS) technologies, and I am hereby excited to invite researchers to submit manuscripts that address theories or applications of quantitative genetics on animal breeding for this Special Issue.

Topics may include, but are not limited to, the following list:

  • Quantitative Genetics Theory
  • Selection Theory
  • (Genomic) Breeding Value Estimation
  • Genome-Wide Association Studies
  • Genome Editing
  • Marker-Assisted Selection
  • Pedigree-Based Selection
  • Genotype Phasing and Imputation
  • Breeding Program Design, Evaluation and Optimization

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 papers will be 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 monthly 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 550 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.

A genome-wide association study (GWAS) was performed on the intramuscular fat percentage in pork chops in commercially available swine in Canada. The Duroc, Iberian, Lacombe, Berkshire, and Pietrain breeds were crossed with Large White sows, and their F1 offspring were ranked according to the intramuscular fat percentage (IMF %) obtained in their longissimus dorsi (LD) muscle loin chops. The ideal IMF % is considered to be >3%, whereas the average is ~1.5% in North American pork. The genetics of the top 10% and bottom 10% from our sample population were analysed by using 80,000 single nucleotide polymorphism (SNP) microarrays in the GWAS. Our sample population had an average IMF % of 2.5 ± 0.7%, but some pork achieved >7% IMF. GWAS analysis revealed SNP markers which were associated with the highest marbled pork chops on chromosomes 5, 7, and 16. Using the Sus scrofa/ susScr 11.1 map, we determined that the nearest genes were sarcospan (SSPN), Rh-associated glycoprotein (RHAG), and EGF-like fibronectin and laminin G (EGFLAM), which can be linked with muscular dystrophy disorders. We tested a subpopulation of Duroc-sired animals and found a different set of markers close to glycine receptor beta (GRLB) and potassium channel 3 (KCNJ3) on chromosomes 8 and 15. Based on our results, we could achieve pork with a good IMF of >4% from animals commercially bred and raised to standard market weights of 110 kg. The choice of obtaining a good marbling line of pigs is not necessarily breed-specific, but it is line-specific. Full article
