How long does the transmission of porcine reproductive and respiratory syndrome virus persist?
The porcine reproductive and respiratory syndrome (PRRS) virus has an enormous impact on the economic benefits of the global pig industry. This disease increases mortality and reduces pig production performance and growth rate, and increases the cost of vaccines and medications. Although many prevention and control measures have been proposed, their effectiveness after implementation still varies, so these measures are not suitable for some pig farms. The PRRS virus has long-lasting infectious pathogenicity and can spread both horizontally and vertically. Fetuses in the uterus and pre-weaning piglets are infected by this virus late, and it can spread throughout the entire piglet barn through virus-contaminated bedding.

What pathogenic effects does feed contamination have on fish?
Because some feed products currently contain bacteria at levels far exceeding the standard, mass fish deaths occur from time to time after fish eat contaminated feed. Based on the disease symptoms in fish, it can be roughly divided into two types: acute type (explosive) and chronic type. 1. Acute type (explosive type): After fish eat contaminated feed, disease onset occurs in as much as 3 to 5 days, or as little as 1 to 2 days, with symptoms appearing; severely affected fish have already died, and the number of dead fish shows a gradually increasing trend, but feeding is not affected, and most fish can eat normally.

Key Technical Points for Feeding and Management of Does During the Breeding Period
The purpose of raising female sika deer is to require does to have high fertility, a healthy constitution, and to produce superior offspring. Whether does can produce superior offspring is not only related to the breed of the doe, but also extremely closely related to feeding and management. Only good feeding and management can enable does to give full play to their superior production performance. According to the nutritional needs and feeding and management characteristics of does at different stages, doe feeding and management can be divided into three periods, described as follows: I. Feeding and Management of Does During the Mating Period Every year
