Genetic association of polymorphisms in porcine RGS16 with porcine circovirus viral load in naturally infected Yorkshire pigs

Seung-Hoon Lee, Kyu-Sang Lim, Ki-Chang Hong, Jun-Mo Kim

J Anim Sci Technol 2021;63(6):1223-1231.
https://doi.org/10.5187/jast.2021.e105

Regulator of G protein signaling 16 (RGS16) is known to be associated with porcine circovirus type 2 (PCV2). PCV2 associated disease (PCVAD) is a serious problem in the swine industry. The representative symptoms of PCVAD are high viral titer proliferation and decreased average daily gain. In this study, we identified single nucleotide polymorphisms (SNPs) in the RGS16 region, including the upstream region. Of the 22 identified SNPs, rs332913874, rs326071195, and rs318298586 were genotyped in 142 Yorkshire pigs. These SNPs were significantly as...

Accuracy of genotype imputation based on reference population size and marker density in Hanwoo cattle

DooHo Lee, Yeongkuk Kim, Yoonji Chung, Dongjae Lee, Dongwon Seo, Tae Jeong Choi, Dajeong Lim, Duhak Yoon, Seung Hwan Lee

J Anim Sci Technol 2021;63(6):1232-1246.
https://doi.org/10.5187/jast.2021.e117

Recently, the cattle genome sequence has been completed, followed by developing a commercial single nucleotide polymorphism (SNP) chip panel in the animal genome industry. In order to increase statistical power for detecting quantitative trait locus (QTL), a number of animals should be genotyped. However, a high-density chip for many animals would be increasing the genotyping cost. Therefore, statistical inference of genotype imputation (low-density chip to high-density) will be useful in the animal industry. The purpose of this study is to inv...

Assessment of testicular steroidogenic enzymes expression in experimental animal model following withdrawal of nandrolone decanoate

TaeSun Min, Adhimoolam Karthikeyan, Ki-Ho Lee

J Anim Sci Technol 2021;63(6):1247-1264.
https://doi.org/10.5187/jast.2021.e102

Anabolic steroids are frequently used to increase the growth rate of meat-producing animals. Exposure to an anabolic-androgenic steroid, nandrolone decanoate (ND), is associated with expressional reduction of testicular steroidogenic enzymes. However, the effect of withdrawal of ND exposure on the expression of these testicular molecules has not been thoroughly explored. The current research investigated expression changes of testicular steroidogenic enzymes in rats at several recovery periods (2, 6, and 12 weeks) after the stop of ND treatment...

Digestibility of pet food can affect the health of dog, especially of aged animals. To maintain the health of dogs in an overall good status it is necessary to provide nutritionally balanced food. For example, the digestibility of dogs was known to be decreased along aging. In addition, losing teethes is an often event in aged dogs that could induce a problem to eat a large size dry pet food. Nonetheless, few detailed information is available on the most suited feeding for aged dogs. As part of the nutritional study of food for aged dogs, in th...
