How to Perform Routine Maintenance on a Fermentation Bed When using a fermentation bed for raising pigs, daily management and maintenance are just as crucial as the setup itself. Proper care ensures that the system functions efficiently and remains hygienic for the animals. Here are some key points to keep in mind: 1. **Maintain Optimal Moisture Levels** The moisture content of the fermentation layer is critical for microbial activity. The ideal range is generally between 50-60%. You can test this by squeezing a handful of the material — it should feel moist but not drip. This level supports the fastest microbial growth. However, the top 10 cm layer tends to be drier, typically around 30-40%. It should feel slightly dry to the touch, and not too wet. A small amount of water can be sprayed on the surface if needed, but avoid making it overly damp. Excess moisture can reduce air circulation and make the bedding uncomfortable for the pigs. 2. **Add Active Ingredients When Needed** While it's usually not necessary to add substances like brown sugar or urea, doing so during colder months can help kickstart fermentation. If the fermentation slows down over time, a small addition of these ingredients can boost the process. Always follow the manufacturer’s guidelines when adding any supplements. 3. **Keep the Environment Clean** With the use of fermentation auxiliaries, the bedding can last for years without needing full cleaning. The waste is continuously broken down through fermentation, becoming less and thinner over time. If you plan to use the fermented material as fertilizer or feed, you can remove it periodically. Just remember to replenish the litter and microbial activators to maintain the system’s efficiency. Whether or not you clean the waste depends on your needs — some farmers choose to leave it for longer periods if they don’t need it immediately. 4. **Careful Management for Sows** Fermentation beds are commonly used for all types of pigs, including sows. During the week before farrowing, it's important to avoid exposing piglets to sawdust or debris that could cause infections. If wounds occur, consider temporarily moving the sow or changing the bedding for a few days until the wound heals. During pregnancy, the sow’s belly may come into contact with the bedding, so it’s best to let fresh sawdust sit for a few days before use to prevent possible allergic reactions. Allergies are rare, but if redness or irritation occurs, it usually resolves within a few days without medication. For more details, visit the official website or consult a specialist.
Gantry Type Video Measuring Machine
The gantry-type Video Measuring Machine can efficiently detect the contours, surface shapes, dimensions, angles, and positions of various workpieces. It is mainly used to measure the size and angle of parts and components that are difficult or impossible to measure with a caliper and angle ruler but play an important role in assembly. It can also be used to take pictures of some parts and components to analyze the causes of defects, especially for PCB boards, films, protective films, optical glass, electronics, large sheet metal parts, connectors, precision mechanical parts, electronic components, semiconductor components, and other industries, It can achieve rapid and accurate detection in large quantities.
advantage:
1. Adopting a high-power industrial high-definition color CCD and a continuous automatic zoom depth lens with fixed frame position, the zoom rate does not require calibration, greatly improving work efficiency and measurement accuracy.
2. Images can be output to electronic computer software for surveying and mapping engineering storage. It can be used for photography, copying, and storage.
3. It can inspect the specifications of buried holes, pipe trenches, etc. on the upper surface of the tested object block. The image and color tone on the surface of the product workpiece can be clearly seen.
