Distillers' grain is a by-product often used as pig feed, but it should not be overfed, especially when it contains high levels of alcohol and acetic acid. Overfeeding can lead to poisoning and digestive issues, such as constipation, due to the imbalanced nutritional profile. It's recommended that distillers' grain make up no more than 30% of the daily feed intake. To ensure balanced nutrition, it should be supplemented with other feed sources. Pregnant and lactating sows should avoid this type of feed altogether.
Leftover food scraps or soup are commonly used to feed pigs, but they should not be given to young pigs or breeding stock. These leftovers are best suited for finishing pigs, provided they are handled properly. Before feeding, impurities should be removed, the soup should be reboiled, and then cooled down to prevent contamination and gastrointestinal diseases like gastroenteritis.
When feeding vegetable-based feeds to pigs, it's important to use proper methods. While some vegetables are easily consumed, they must be fed in a scientific manner. Overfeeding raw vegetables can cause diarrhea or other digestive problems. When cooking, care should be taken to avoid harmful substances—such as nitrites in beet leaves—which can lead to poisoning if not properly managed.
Substitute feeds have become more common as the feed market develops, with products like feather meal, bone meal, and full-price feeds replacing traditional ingredients. However, these substitutes must be used in the correct proportions and according to scientific guidelines. Improper use can result in poor growth, health issues, or even harm to the pigs. Always follow recommended feeding practices to ensure optimal results.
