Background
The DNA-test for the genetic variation in the gene identified melanocortin-4 receptor (MC4R) is associated with growth and leanness. The producer and breeder can decide if they wish to choose the fast growth form of the gene (298Asn, A-nucleotide variation) or the lean/efficient growth form of the gene (298Asp, G-nucleotide variation). Effects are 3 days less to market weight for animals homozygous for the growth allele compared to those homozygous for the lean allele. Pigs homozygous for the lean allele have 8 percent less backfat and have a high feed conversion rate.
Test specific information
-
Age
The genetic factor is continuously present, and affects the meatquality.
Throughput
Normally the result can be expected within 15 working days. This turn-around-time starts when both the sample and the fully filled-out and signed submission form have been received.
Location of disease or trait
Meat quality can be assessed in the meat.
Breed dependence
For this test samples from all breeds are accepted.
Sample type
For this DNA test we accept the following materials: Hair, Semen, Blood EDTA, Blood Heparin, Tissue. Please contact PharmaDNA if you wish to submit other material as listed.
Result
Meat quality is based on many genetic factors. For each factor, a separate test result will be returned.
Inheritance
Various genetic factors influencing meat quality are inherited in a dominant or recessive mode. Meat quality is influenced by a large number of genetic factors.
Severity of Disease
Genetic characteristics are not a disease.
