Gene (Rendement Napole)
What is RN?
Rendement Napole (RN) gene is a swine gene found to cause
low ultimate pH and water holding capacity (WHC) in pork.
The gene is also commonly called the "acid meat gene"
or "Hampshire effect" due to the low ultimate meat
pH it causes and because this gene has primarily been observed
in purebred or crossbred Hampshire populations.
In genetic terms, inheritance of the RN gene is at a single
locus and there are 2 alleles: one dominant mutant allele
(RN-) and one recessive normal allele (rn+). The dominant
RN- allele causes low ultimate pH of all muscles, especially
the loin and ham muscles. Extensive research on the
effects of the RN gene on pork production, especially on pork
quality, has been carried out worldwide since it was discovered.
Studies on the impact of the RN gene on fresh and processed
pork quality have consistently shown that the RN gene has
negative effects on meat pH, WHC, colour, drip loss, cooking
loss and processing yield.
