AI Article Synopsis
- The intestinal microbiota plays a crucial role in the growth and health of pigs, but differences between Duroc and Yorkshire boars are not well understood.
- A study showed that Yorkshire boars reach 100 kg at a younger age, with less backfat and a larger eye muscle area compared to Duroc boars.
- Analysis of their gut microbiota revealed greater diversity and specific microbial groups in Yorkshire boars, suggesting that these gut bacteria may help explain their superior growth performance and lean meat yield, which could inform better pig breeding practices.
Article Abstract
The intestinal microbiota is required for maintaining the development and health of the host. However, the gut microbiota contributing to the regulation of the growth performance and health of Duroc and Yorkshire boars remains largely unknown. In this study, we first evaluated the difference in the growth performance between Duroc and Yorkshire boars when their body weight reached 100 kg. Relative to Duroc boars, Yorkshire boars weighed 100 kg at a younger age and exhibited a significantly lower backfat thickness and eye muscle area. Microbial analysis of the fecal samples revealed a marked difference in gut microbiota composition between the two pig models and remarkably increased α-diversity in Yorkshire boars compared to Duroc boars. Further analysis indicated that Bacteroidota, Prevotellaceae, and Ruminococcaceae might be associated with the growth performance and lean meat rate of Yorkshire boars. Taken together, these results highlight that Yorkshire boars exhibit a faster growth rate and higher lean meat rate compared to Duroc boars, and these differences may be attributed to the influence of the gut microbiota, thereby providing valuable insight into optimizing pig breeding systems and selecting terminal paternal sires to enhance overall productivity and quality.

Article Synopsis
- Porcine respiratory diseases significantly affect pig production, with common pathogens like Streptococcus suis and Pasteurella multocida also posing risks to human health.
- The overuse of traditional antibiotics has led to antimicrobial resistance, highlighting the need for alternative treatments such as antimicrobial peptides (AMPs).
- Oreochromicin-2 (Oreoch-2), an AMP from fish, showed promising results in reducing bacterial loads and improving health in pigs, making it a potential candidate for treating respiratory diseases in swine.
Comparison of Development and Antioxidative Ability in Fertilized Crossbred (Yorkshire × Landrace × Duroc) Oocytes Using Duroc and Landrace Sperm.

Pig production through crossbreeding methods is a pillar of the swine industry; however, research on the fertilization ability of male pigs in crossbreeds is lacking. Therefore, this study investigated the effects of Duroc sperm (DS) and Landrace sperm (LS) on fertility in Yorkshire × Landrace × Duroc (YLD) oocytes. Sperm were collected from the Duroc and Landrace species, and sperm characteristics, viability, and acrosome reactions were analyzed using flow cytometry.

Embryo-uterine interaction during embryo implantation depends on the coordinated expression of numerous genes in the receptive endometrium. While DNA methylation is known to play a significant role in controlling gene expression, specific molecular mechanisms underlying this regulatory event remain elusive in early porcine pregnancy. Here, we investigated the genome-wide DNA methylation landscape in the Yorkshire and Meishan pig's endometrium.

Introduction: Intracardiac echocardiography (ICE) is an essential imaging modality for electrophysiology procedures, allowing intraprocedural monitoring, real-time catheter manipulation guidance, and visualization of complex anatomic structures. Four-dimentional (4D) ICE is the next stage in the evolution of the technology, permitting 360° rotation of the imaging plane, simultaneous multiplanar imaging, and volumetric acquisition, similar to transesophageal echocardiography (TEE). In this study, we report our experience with a novel 4D ICE catheter (NuVision, Biosense Webster) in structural electrophysiology procedures and difficult ventricular ablations in a swine preclinical model.

Introduction: The recent emergence of PRRSV strains NADC30 and NADC34, along with their recombination with HP-PRRSV-like strains, has added complexity to PRRS control strategies on swine farms. Given the high variability and recombination potential of PRRSV, continuous monitoring of the virus's clinical epidemiology is essential for effective prevention and control.
Methods: This study isolated a PRRSV variant, designated SDVD-NMG2023, from approximately 65-day-old pigs, showing a mortality rate of around 15% within the herd.
