At present, many rural households have a large amount of bran and use it as feed for pigs or other livestock. Bran is indeed a valuable feed source for animals due to its high nutritional content. However, if the feeding process is not done properly, the expected benefits may not be achieved. To make the most of this resource, it's essential to understand the nutritional value and proper usage of bran. Below are some key points about bran and how to effectively use it when feeding pigs.
Bran is a by-product of wheat milling, primarily consisting of the outer layer of the wheat kernel and a small amount of starch. Compared to wheat bran, it has higher levels of crude protein and minerals, especially phosphorus. In fact, 80% of the phosphorus found in wheat grain is concentrated in the bran. With its rich protein content, including a good amount of lysine, and its appealing taste, bran makes an excellent feed for pigs and other livestock—especially for pregnant sows and breeding animals. Pigs particularly enjoy it because of its palatability and the presence of salt, which can help with digestion.
The protein quality of bran surpasses that of corn and wheat. It is also rich in B-vitamins but lacks vitamins A and D. Therefore, when feeding piglets with bran, it’s important to supplement their diet with calcium, vitamin A, and vitamin D. Bran has a soft texture and a large volume, making it ideal for sows. Feeding sows 10% to 25% bran before and after farrowing can help prevent constipation and reduce the risk of excessive milk production. However, for finishing pigs, the amount should not exceed 20% of their total diet, and for weaned piglets, it should be limited to 5% to 10%. Proper management ensures that the nutritional benefits of bran are fully utilized while avoiding potential deficiencies.
