As a nutritional component of pig feed, high-quality corn has a dry matter weight of 86%, digestible energy 14.39 MJ/kg, crude protein content of 9.4%, crude fat content of 3. 1%, crude fiber content of 1.2% and nitrogen-free extract content of 71.60.
The nutritional value of ordinary rice as feed is 86% dry matter, digestibility 1 1.25 MJ/kg, crude protein 7.8%, crude fat 1.6%, crude fiber 8. 1%, and nitrogen-free extract 63.8%.
As a nutritional component of pig feed, common soybean contains 87% dry matter, digestibility 16.6 1MJ/kg, crude protein 35.5%, crude fat 17.3%, crude fiber 4.3%, and nitrogen-free extract and crude ash 25.7%.
From the above analysis of corn, rice and soybean as nutritional value components of pig feed, corn and rice belong to a kind of energy feed, while soybean belongs to protein feed. Their respective nutrients are different. From the scientific use of feed, the nutritional components of pig feed meet the nutritional substances needed by pigs at various growth stages, and are artificially and reasonably matched according to a certain proportion, so that the nutrition of grain can be fully utilized without causing waste and loss, and the functions of various nutritional components contained in grain can be maximized, so that the nutritional components of feed can be fully utilized and play their due roles, thus improving the conversion rate and utilization rate of feed.
In a word, it is suggested that corn, rice and soybean should not be used as pig feed alone, but should be reasonably matched according to the nutrients needed in each stage of pig growth, so as to improve the utilization rate and conversion rate of feed, make full use of feed nutrients to the greatest extent and avoid wasting feed.
