Corn is one of the most widely used feed ingredients and is considered a valuable resource in animal nutrition. However, when formulating feed with corn, there are several challenges that need to be addressed to ensure optimal feeding results. To make the most of this ingredient and improve pig performance, it's essential to understand and apply proper feeding techniques. Here are some key methods for feeding pigs with corn.
First, after saccharification, the feed becomes more palatable and easier for pigs to consume. The process involves cooking corn flour and converting some of the starch into sugar. This not only improves taste but also encourages faster eating. The method is as follows: mix the corn flour in a tank, add two times the amount of hot water to create a paste, then spread a 5 cm thick layer of dry powder on top. Allow the mixture to rest for 3-4 hours to complete the saccharification process.
Second, soaking the corn before feeding helps improve digestibility. Soaking allows the corn to absorb water, expand, and become softer, making it easier for pigs to chew and digest. The recommended method is to soak the corn flour in water at a ratio of 1 to 1.5 times the weight of the flour for approximately 2 hours.
Third, it's important to supplement protein in the diet since corn has a low protein content and poor quality. To meet the nutritional needs of pigs, especially growing pigs, you can add 15% soybean meal or rapeseed cake to the feed. For piglets, adding 5% fish meal can significantly improve their growth and development.
Fourth, mineral supplementation is crucial because corn is deficient in essential minerals. To ensure balanced nutrition, include bone meal, calcium hydrogen phosphate, and trace minerals such as selenium, iron, copper, zinc, and manganese in the feed.
Lastly, vitamin supplementation is necessary as corn lacks sufficient vitamins. Providing green feed is ideal, but if it's unavailable, adding a multivitamin supplement to the diet can help maintain the health and well-being of the animals. Ensuring a balanced diet with proper processing and supplementation will lead to better growth, improved health, and higher productivity in pigs.
