Feedstuff additive for improving oil and fat assimilation utilization ratio and preparation method thereof

Abstract

The invention discloses a feed additive for improving the digestion utilization ratio of fat and a method for preparing the same. The feed additive comprises the following components in weight portion: 0 to 35 portions of bile acid, 0 to 15 portions of taurine and 20 to 80 portions of defatted rice bran. The invention has the advantages that: by practice, we finds that if proper amount of bile acid and taurine is added in the feed, the activity of pancreatic lipase is enhanced, the digestion utilization ratio of fat is greatly improved, the liver function is strengthened, the incidence rate of animal fatty liver and the death rate of animals are lowered, so that the addition level of fat in the feed can be reduced, and the aim of saving feed cost is achieved. In poultry breeding, the utilization ratio of fat is improved by 10 to 25 percent; in pig feeding, the utilization ratio of fat is improved by 10 to 25 percent; and in the fish, the utilization ratio of fat is improved by 10 to 25 percent, and the incidence rate of liver-gall syndrome of fish is greatly lowered.

Description

technical field [0001] The invention relates to a feed for livestock and poultry and aquatic products and a preparation method thereof, in particular to a feed additive for improving the digestibility and utilization rate of oil in the feed and a preparation method thereof. Background technique [0002] In order to tap the production potential of animals and make animals grow faster, people not only add a lot of protein to the feed, but also add a lot of energy substances, especially oil, which is the most effective way to provide energy, is favored by everyone. [0003] However, due to the sharp increase in the prices of agricultural by-products and livestock products in recent years, the addition of fats and oils in feed is limited. How to improve the utilization rate of digestion and absorption of oil has become the focus of people's attention. [0004] Studies have found that the fat in the feed needs to be digested before it can be absorbed, and the digestion of fat mu...

AI Technical Summary

Problems solved by technology

The active release, play and stable maintenance of pancreatic lipase all require the participation of bile acids, but the secretion of bile acids is insufficient in animals of any age, especially young animals. They not only secrete pancreatic lipase Insufficient, bile acid secretion is also insufficient, and even a complete enterohepatic circulation of bile acids cannot be established
