A measuring instrument for quantitatively evaluating the cylindricity of a cylinder by measuring the actual contour of the cylinder using the precise rotation centerline as the reference standard and the precise linear motion guide rail as the reference standard. It can be used to measure cylindrical shape errors (roundness, cylindricity, straightness, and flatness), position errors (coaxiality and verticality), etc. The cylindrical Roundness Tester is mainly used to measure the roundness, cylindricity, straightness, concentricity, coaxiality, flatness, parallelism, perpendicularity, surface waviness, discontinuous surface, etc. of various regular and irregular circular workpieces. It can also perform spectrum analysis, wave height analysis, eccentricity, shaft bending analysis, and runout analysis on workpieces. This device has excellent cost-effectiveness, full measurement capability, and is easy to learn and use.

Feed the weaned pigs
Weaning is a critical period for piglets, and the feeding strategy during this time plays a vital role in their health and growth. Overfeeding can lead to digestive issues such as indigestion and diarrhea, while underfeeding may cause stress from hunger, which can negatively impact their development. To manage this, it's important to implement a controlled feeding schedule. For the first 4-5 days after weaning, feed the piglets smaller amounts more frequently—around 6-8 times per day. The daily feed quantity should be approximately 70% of what they were previously consuming. After this initial phase, gradually increase the amount of feed as the piglets adjust.
Monitoring the piglets' feed intake is essential. Check the feed troughs regularly. If there’s only a small amount of leftover feed and no fine particles or pellets, it means the last feeding was appropriate. If the trough is clean and moist, it suggests that the previous feeding was too little, so you should increase the amount. On the other hand, if there are leftovers, it indicates overfeeding, and you should reduce the portion, removing any uneaten feed.
Observing the piglets’ feces is also an effective way to assess their digestion. In the first three days after weaning, their stools should be soft but not runny, gradually changing from yellow to brown. This is considered normal. Monitor the feces for 12–15 hours. If the stool becomes pasty, pale gray, or contains undigested feed, it may signal digestive distress. In such cases, stop feeding for one meal and reduce the next portion by half. Gradually reintroduce feed based on their condition.
If the feces become soft and dark, you can increase the feed back to 80% of the normal amount. If the feces are mushy, green, or contain mucus, it’s a sign of more serious issues. In this case, skip two meals and offer only a small amount of feed in the trough for the third meal. Slowly increase the amount over the next few days until the piglets return to a regular feeding pattern.
After weaning, the feeding system should closely match what the piglets experienced during the lactation period. Always ensure access to clean, fresh water. The initial feeding restriction period should last 7–10 days. After that, transition to four meals a day. Proper vaccination and hygiene are crucial during this time. Regular cleaning and disinfection help maintain a healthy environment, keeping the area dry and sanitary to support the piglets' well-being.
