Pig feed treatment technology

In the first step, acidification treatment is essential for weaned piglets suffering from insufficient gastric acid. To improve digestion and reduce the risk of harmful bacteria, feed can be acidified by adding 1% to 3% citric or lactic acid to water or feed, lowering the pH to around 5. Alternatively, adding 0.3% pepsin to the feed can enhance digestion and inhibit the growth of pathogenic microorganisms in the gut. Next, fermentation treatment is a valuable method to improve feed quality and promote gut health. A mixture of ingredients such as baking soda, liquor, sea bream powder, spicy glutinous rice, Liuyi, tea, Guanzhong, yam, medlar, dried tangerine peel, and glucose is ground and mixed together. Then, 5 egg whites and 6 kg of fine rice bran are added, along with enough water to create a moist, compact mass. The temperature should be maintained between 35°C and 45°C, especially during colder months, using plastic film for insulation. After three days, when the mixture turns yellow and emits a strong sweet apple aroma, it becomes a homemade "medicine strain." This fermented material is then dried in the shade. When used for feeding, mix 150g of the "medicine strain" into 50kg of feed along with 50kg of water, ensuring similar temperature and humidity conditions. Let it ferment for 24 hours until a strong liquor-like apple scent develops. Feed this mixture four times daily, about 2–3 kg per meal, and offer some fresh, juicy feed after each serving. Lastly, saccharification treatment enhances the digestibility and palatability of starchy feeds like corn, barley, and sorghum. Crushed concentrate is placed in a container, then 2–2.5 times its volume of hot water (80–90°C) is added, stirred into a paste. To maintain the temperature, a thin layer of dry material is sprinkled on top, covered with a lid or plastic film, and kept at 55–60°C for approximately 3–4 hours. The saccharified feed should be used within 14 hours to prevent spoilage. This process not only improves flavor but also makes the feed easier for animals to digest.
