Background
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
-
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.
