ABSTRACT Infectious disease is a major constraint for all species produced via aquaculture. The majority of farmed fish and shellfish production is based on stocks with limited or no selective breeding. Since disease resistance is almost universally heritable, there is huge potential to select for improved resistance to key diseases. This short review discusses the current methods of breeding more resistant aquaculture stocks, with success stories and current bottlenecks highlighted. The current implementation of genomic selection in breeding for disease […]

Genomics will improve the efficiency of beef cattle genetic improvement programs through the incorporation of genomic predictions into traditional genetic evaluations. The global dairy cattle breeding industry has been changed considerably in the last year through the implementation of genomic selection. Now proven to work in dairy cattle breeding, the challenge remains for the beef industry to successfully implement this technology. The primary challenge in beef cattle is the required resource population that relates genomic profile to phenotypic performance, which […]

The first studies to identify, characterize and use molecular markers to characterize genetic resources and generate tools for animal breeding and management date from the end of the 80s. In the last 20 years the technologies to generate molecular data went through several innovation cycles. The last wave of technological innovations represents a true revolution, bringing methods to identify and genotype SNP (Single Nucleotide Polymorphism) markers in large scale. High density DNA chips were generated to genotype from tens of […]
