Characterization analysis of Rongchang pig population based on the Zhongxin-1 Porcine Breeding Array PLUS.

ABSTRACT:

Objective

To carry out a comprehensive production planning of the existing Rongchang pig population from both environmental and genetic aspects, and to establish a closed population with stable genetic diversity and strict pathogen control, it is necessary to fully understand the genetic background of the population.

Methods

We genotyped 54 specific pathogen free (SPF) Rongchang pigs using the Zhongxin-1 Porcine Breeding Array PLUS, calculated their genetic diversity parameters and constructed their families. In addition, we also counted the runs of homozygosity (ROH) of each individual and calculated the value of inbreeding coefficient based on ROH for each individual.

Results

Firstly, the results of genetic diversity analysis showed that the effective population siz
