The DNA-test for genetic variation in the cholecystokinin type A receptor (CCKAR) is associated with feed intake, hunger and obesity. Animals with at least one copy of the dominant G-variant have, on average 5 percent higher daily feed intake, 3 percent higher daily gain and 3 percent less days to reach 180 kg. These values are based on a comparison between animals with at least one G versus animals which are homozygous A. The test detects genetic variation in amino acid 179.
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.
