Abstract

The invention relates to an organic acid feed additive for improving the growth performance of pigs. The pigs at a fattening stage can have the symptoms of digestive function disorder and the like under the condition that factors such as a farm environment, a pig group, a feed, feeding management and the like are changed, so that adverse reactions such as low feed intake, slow growth and the like, which are one of main reasons of low growth performance of the pigs, are caused accordingly. The additive comprises fumaric acid, citric acid, succinic acid and propionic acid, wherein 3 to 5 or 6 to 8 mass parts of fumaric acid, 1 to 2 or 3 to 4 mass parts of citric acid, 4 to 6 or 2 to 4 mass parts of succinic acid and 3 to 5 mass parts of propionic acid are added into a feed for the pigs at the fattening stage; and 3 to 5 mass parts of fumaric acid, 1 to 2 mass parts of citric acid, 4 to 6 mass parts of succinic acid and 3 to 5 mass parts of propionic acid are added into a feed for ablactated piglets. The product is taken as a feed additive or a pig feed.

Description

Technical field:

[0001] The invention relates to a pig feed additive for improving pig growth performance. Background technique

[0002] Pigs in the fattening stage will have digestive disorders and other phenomena when factors such as farm environment, pig herd, and feed change. The resulting adverse reactions such as low feed intake and slow growth are the reasons for poor growth performance of pigs. One of the main reasons.

[0003] In order to maximize the annual litter rate of sows in modern intensive pig raising, the lactation period of piglets is shortened from 5 to 6 weeks to 3 to 4 weeks. However, early weaned piglets are prone to diarrhea, accompanied by slow growth and high mortality. Weaned piglets aged 3 to 4 weeks under the dual pressure of nutritional and environmental changes usually show reduced feed intake, slow or no weight gain, prone to diarrhea, high morbidity, and even death. The acidic environment in the stomach of piglets before weaning is mainly ...
