1.Feed Should Be Diverse and Balanced: The feed given to Swines, including green forage, coarse forage, and concentrated feed, should be properly combined to ensure that all nutritional needs are met.
2.Consider the Relationship Between Feed Volume and Swine Intake: The size of the feed can be measured by the dry matter content. For Swines, the daily dry matter requirement is 2.5–4.5 kg per 100 kg of body weight. The ratio of dry matter for green forage, coarse forage, and concentrated feed should be 5:3:2.
3.Feed Should Be Palatable and Easy to Digest: Feed with high energy and protein content and low fiber content is more palatable and easier to digest. Conversely, feed with low energy and protein and high fiber content is less palatable and harder to digest. When formulating Swine feed, more green forage should be used, and the quality of coarse forage should be good.
4.Choose Different Types of Diets for Different Swine Groups: Generally, piglets, breeding boars, and fattening Swines in the finishing stage should be fed a concentrated feed-based diet, where concentrated feed makes up over 50% of the daily intake. Breeding sows and replacement sows should be fed a green forage-based diet, with green forage making up over 50% of the daily intake. Growing piglets should be fed a bran-based diet, with bran making up over 50% of the daily intake.
