This study aimed to evaluate the growth performance and health status of commercial pigs in different body weight (BW) groups and develop methods for identifying slow-growing pigs. The research observed 79 commercial pigs grouped from 104 to 202 days of age, collecting data on BW, feed intake, and body condition score (BCS) from caliper. Results showed that BCS were highly correlated with BW (r > 0.

- Pseudorabies virus (PRV) is a DNA virus affecting various animals, and a study in China examined its prevalence by analyzing blood samples collected from 16 provinces in 2022.
- The study employed ELISA to detect PRV gE antibodies in 161,880 samples from 556 swine farms, revealing a 12.36% seroprevalence at the individual animal level and a higher 46.22% at the farm level.
- Findings indicate seasonal factors and farm geography influence PRV infection rates and highlight five areas of high prevalence, aiding future prevention strategies against the virus.
Article Synopsis
- Porcine epidemic diarrhea (PED) is a serious viral disease affecting pigs, leading to significant economic losses globally, with vaccination being the most effective control method available.
- An analysis of 240 PED outbreak cases from various farms found that herd movement and delays in piglet production were major factors for PED spread, with higher rates of transmission during warmer months.
- Results indicated that using highly virulent live vaccines and commercial inactivated vaccines significantly reduced outbreak frequency and duration, leading to better financial outcomes for farms compared to other vaccination strategies.
