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
The genetic factor is continuously present, and affects the meatquality.
The turn-around-time of a test depends to a large extent on the logistics of sample transportation to the laboratory. After receiving the sample at the test location, you can normally expect the result within 10 working days. A longer delivery time applies to tests carried out by a Partner Lab.
Location of disease or trait
Meat quality can be assessed in the meat.
For this test samples from all breeds are accepted.
For this DNA test we accept the following materials: Hair, Semen, Blood EDTA, Blood Heparin, Tissue. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.
Meat quality is based on many genetic factors. For each factor, a separate test result will be returned.
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.
