How are genomics and DNA improving the production of livestock?

How are genomics and DNA improving the production of livestock?

How does genomics help livestock producers? Genomics makes clear what was once unknown. Genomic testing can help predict future profitability potential. This in turn allows producers to optimize the profitability and yields of their herds by making different animal selection and strategic breeding decisions.

What are the benefits of genetically modified cows?

Genetic engineering holds great potential in many fields, including agriculture, medicine and industry. Genetic modification can increase the yield from farm animals, for example cows can be engineered to produce more milk for the same size of herd.

What does Genomics contribute to animal breeding?

Genomic selection gives breeders new opportunities to meet the increasing demand for animal protein in a sustainable and animal-friendly way. Until recently, the work of breeders revolved primarily around studying and observing traits such as productivity, disease resistance and longevity.

What genetic traits lead to high quality beef?

PPP1R3B has been reported to be associated with meat quality traits in cattle, including pH, meat color, and shear force (Edwards et al., 2003; Kayan, 2011; Cinar et al., 2012), and skeletal muscle development in humans (Munro et al., 2002). In addition, this gene is associated with glucose and glycogen metabolism.

How is genomic testing done in cattle?

The most common genomic test available for cattle reads around 50,000 DNA markers or SNPs using a technology embedded in a small chip called a SNP chip (Figure 3). The SNPs are changes in the DNA that can be responsible for genetic variation among animals. Blood and hair samples for genomic testing.

What are genomics in cattle?

Genomics studies the structure, function, evolution and mapping of DNA and the genetic makeup of animals. It deals with the complete set of genes and genetic material found in a cell or organism. Genomic technologies draw both producer interest and research investment in the beef industry.

What are the benefits of genetically modifying animals?

Genetic engineering of animals offers solutions for improving public health and enhancing quality of life. The benefits include advancing human health, enhancing food production, reducing environmental impact, optimizing animal health and welfare and production of cutting edge industrial applications.

Why the study of genomes is important in animal genetics?

Genome-based analyses that increase knowledge of the genetic basis of production traits will lead to the development of new technologies that optimize animal breeding strategies and inform management decisions to realize the maximum production potential of animals across environments.

What is beef genetics?

How are beef genetics measured? EPD’s are estimates of an animal’s genetic value for a given trait that will be passed to offspring. Traits include calving ease, birth weight, weaning weight, yearling weight, marbling, rib eye area, maternal milk and many more.

What cow breed has the best temperament?

What cow has the best temperament? The more docile beef breeds are Blonde d’Aquitaine, Beefmaster, British White, Devon, Galloway, Gelbvieh, Hereford, Lincoln Red, Maine Anjou, Murray Grey, Pinzgauer, Red Poll, Simmental, and South Devon.

How does genomic testing work for beef cattle?

Genomic tests Recently, genomic testing for beef cattle has evolved to include “high-throughput” testing, meaning that thousands of markers (or single nucleotide polymorphisms, or SNPs) are read from an animal’s DNA. Producers need only to submit a blood, hair, or tissue sample from an animal to the breed association (Figure 2).

How is genomic selection used in domestic animals?

Preliminary experiments on genomic selection (GS) were reported on simulated data which revealed that GS can practically be implemented in large animals with longer generation intervals. Later, GS has been successfully implemented in a number of domestic animals to associated genome-wide distributed markers with economically important traits (ETL).

Is the taurine genome in the Bovine Genome Project?

The taurine genome has been sequenced, analyzed, and partially annotated by the Bovine Genome Project which is a collaborative project involving several groups and funding from the United States, Canada, United Kingdom, France, Australia, and New Zealand ( Burt, 2009 ).

When was the first Assembly of a cattle genome?

The first assembly of cattle genome sequence (sevenfold coverage) was published on April 24, 2009 in the Bovine Genome Sequencing and Analysis Consortium ( http://bovinegenome.org/?q=bovine_genome_consortium; Bovine Genome Sequencing and Analysis Consortium, 2009 ).
