In pigs, the gene for cholecystokinin type A receptor (CCKAR) is associated with an animals growth via physiological control of feed intake, hunger fulfilment, and obesity.

There are two variant mutations known to affect feeding in pigs: one to amino acid 471 (CCKAR471, analysed in this test) and one to amino acid 179 (CCKAR179). Both mutations can be useful for reducing production costs for pigs.


Chromosome: 8


Mode of Inheritance: Autosomal Dominant

Also known as: CCKAR

Organ: Multiple systems


Year published: 2006

Clinical Features

CCKAR471 can have either an C or G allele. When a pig is homozygous for G, the average daily gain and daily feed intake is increased compared to homozygous C during the growth period from 35 to 80kg. After reaching this weight, it is unclear if there is an effect on food intake and daily gain up to 180kg.

Additional information

Meat quality is based on many factors. It is influenced by postmortem tenderization, which is a complex structural and functional process that depends on species, genetic background, metabolic status of the animal antemortem, the protein complement of the muscle, and environmental factors.
