To address the safety problems posed by the transportation of boar semen using LN, this study was conducted on the short-term storage of frozen boar semen in dry ice (-79 °C). Boar semen frozen in LN was transferred to dry ice, kept for 1 day, 3 days, 5 days, 7 days, or 8 days, and then moved back to LN. The quality of frozen semen stored in LN or dry ice was determined to evaluate the feasibility of short-distance transportation with dry ice.

The aim of this study was to identify effective genetic markers for the Antigen Processing Associated Transporter 1 (), α (1,2) Fucosyltransferase 1 (), Natural Resistance Associated Macrophage Protein 1 (), Mucin 4 () and Mucin 13 () diarrhea-resistance genes in the local pig breeds, namely Shanghai white pigs, Fengjing pigs, Shawutou pigs, Meishan pigs and Pudong white pigs, to provide a reference for the characterization of local pig breed resources in Shanghai. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLR) and sequence sequencing were applied to analyze the polymorphisms of the above genes and to explore the effects on the immunity of Shanghai local pig breeds in conjunction with some immunity factors. The results showed that both and genes had antidiarrheal genotype GG in the five pig breeds, AG and GG genotypes of the gene were detected in Pudong white pigs, AA antidiarrheal genes of the gene were detected in Meishan pigs, the AB type of the gene was detected in Pudong white pigs, and antidiarrheal genotype GG of the gene was only detected in Shanghai white pigs.

Introduction: The gut microbiota closely relates to host health, whereas the relationship between gut microbiota and testosterone during the development of Meishan male pigs remains unclear. This study investigated the fecal microbiota composition and testosterone level during development in Meishan male pigs.

Methods: Fresh fecal samples of 20 healthy Meishan male pigs were individually collected at 10 and 22 weeks (wk) of age for testosterone content detection and bacteria pyrosequencing analysis.
