Abstract

The invention relates to proanthocyanidin products, a weaned piglet feed containing the proanthocyanidin products, and a preparation method and application of the feed. The weaned piglet feed comprises the following components in parts by weight: 0.01-0.05 part of the proanthocyanidin products, 50-75 parts of corn, 10-25 parts of dehulled soybean meal, 5-20 parts of puffed soybeans, 1-10 parts ofwhey powder, 2-4 parts of fish meal, 0-1.5 parts of wheat bran, 0-2 parts of soybean oil, 1-3 parts of calcium dihydrogen phosphate, 0-1.5 parts of glucose, 0.5-1 part of stone powder, 0-0.5 part of L-lysine, 0-0.1 part of DL-methionine and 0.5-2 parts of a vitamin mineral premix. The proanthocyanidin products and the weaned piglet feed can notably improve the antioxidant ability of piglets, contribute to relieving and repairing intestinal tract damage caused by weaning stress of the piglets, improve intestinal mucosal barrier functions, prevent and treat diarrhoea of the weaned piglets, reduce the death and culling rate and increase the breeding economic benefits.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for weaned piglets. Background technique [0002] The growth performance of weaned piglets (including body weight gain or body weight at the end of nursery) is closely related to piglet health, subsequent growth and development, and even time to market. Due to changes in the environment, feed, management and other factors, weaned piglets are subject to greater stress, and are prone to symptoms such as diarrhea, poor appetite, and slow growth during production, which greatly affects the production efficiency of the pig industry. Weaning diarrhea is an urgent problem to be solved in piglet production, and it is also a worldwide problem. The current situation in China's pig industry, the measure to control post-weaning diarrhea in piglets is the use of high-dose antibiotics. The consequences of a large number of antibiotics and even the abuse of antibiotics are the enhancement...
