On pig farms, feed and water are two of the most routine aspects of management, but they are also where serious problems can arise most easily. Pigs can go a day without eating, but they cannot go a day without drinking. When illness increases in a pig herd, the cause often turns out not to be an infectious disease, but small issues such as moldy feed troughs, clogged water lines, insufficient water pressure, or changing feed too quickly.
First, feed management. Set a high standard at the first checkpoint when raw materials arrive: check corn, soybean meal, wheat bran, and other ingredients for moisture, smell, color, lumps, heating, and mold spots. Do not store high-moisture corn for long. Keep feed bins protected from rain and moisture, and regularly clean their walls and outlets. Check feed troughs at least once a day, especially ad libitum feeders, where feed can accumulate in corners and eventually grow mold. If leftover feed is blackened, sour, or lumpy, remove it immediately. Do not assume that “the pigs will eat it when they get hungry.” Mycotoxins in moldy feed can damage the liver and kidneys and affect immunity when ingested; later injections and medication cannot make up for it.
Feed on a regular schedule. Finishing pigs can eat ad libitum, but you should still check each day how long the troughs stay empty. Give sows a set ration and adjust it according to body condition. For piglets, introduce solid feed in small, frequent amounts and keep it fresh. Do not decide to change feed today and switch entirely tomorrow. It is best to transition over 5 to 7 days, gradually increasing the proportion of the new feed each day. Clean and disinfect feed bins, feed carts, and troughs regularly, and protect them from rats, birds, and moisture. Follow first-in, first-out practices in the feed room; do not leave old feed buried at the bottom for half a year.
Next, water management. Water-line management is easily overlooked. Each day when entering a barn, check the drinkers: Is the water flowing freely? Is the pressure sufficient? Is the drinker at the right height? If a drinker is too high, piglets cannot reach it; if it is too low, sows have difficulty drinking. When water lines are not cleaned for a long time, biofilm can form inside the pipes. The water may look clear, but it can still contain many bacteria. Thoroughly clean the water lines after each batch of pigs is moved out, and check the water quality and flow rate at the line ends once a week. Flush the lines promptly after adding medication to the drinking water, or residue may clog the pipes.
You should also learn to monitor feed intake and water consumption. These two figures are the most sensitive warning signals of herd health. A sudden drop in feed intake may be due to fever, a feed change, mold, or high ammonia levels. A sudden increase in water consumption may be due to heat stress, diarrhea, or kidney disease. A sudden decrease may indicate a clogged water line or insufficient water pressure. Record the feed intake and water consumption for each barn every day and compare them with the previous day and the previous week. This can reveal problems earlier than simply observing the pigs.
Feed and water management is not complicated; the key is consistency. Clean troughs, clear water lines, fresh feed, and gradual feed transitions—if you get these four things right, you can avoid at least half the trouble on a pig farm. Many farmers are always looking for a “miracle drug,” but managing these two daily essentials—feeding and drinking—is the best preventive care.
