Feed additive and expanded feed for protecting liver and gallbladder of Taiwan loach and preparation method thereof

Abstract

The invention provides a feed additive and an expanded feed for protecting liver and gallbladder of Taiwan loach, and a preparation method thereof, and belongs to the technical field of feeds. Each 100 parts of the feed additive comprises 30-40 parts of bile acid, 25-35 parts of sweet wormwood powder, 5-15 parts of taurine, 5-15 parts of glyceryl tributyrate and 10-20 parts of carrier bran powder.The expanded feed for Taiwan loach comprises 200-250 parts of imported fish meal, 50-70 parts of shrimp meal, 30-50 parts of squid meal, 80-120 parts of fermented soybean meal, 280-320 parts of decorticated soy bean meal, 180-220 parts of high-gluten flour, 15-25 parts of calcium dihydrogen phosphate, 20-25 parts of fish oil, 20-25 parts of soybean oil, 3-8 parts of a compound vitamin mixture, 3-8 parts of a mineral and trace element mixture and 3-8 parts of the feed additive for protecting liver and gallbladder. The feed additive provided by the invention has obvious functions of protectingliver and gallbladder, and is convenient for the feeding of loach.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a liver-protecting gallbladder-protecting feed additive for Taiwan loach, an extruded feed and a preparation method thereof. Background technique [0002] Taiwan loach grows fast and tastes delicious. As a nourishing product, it has broad market prospects and has been popular in the market for many years. The domestic market demand reaches 300,000 to 400,000 tons per year, but the actual supply is only 100,000 to 150,000 tons. The gap is large and the supply is in short supply. Therefore, Taiwan loach has always been one of the more popular breeding species. [0003] In recent years, the success rate of shrimp farming has generally been low, and many shrimp farmers have switched to raising Taiwanese loach, so many farmers still use shrimp feed for Taiwanese loach farming. On the one hand, the classification status and nutritional requirements of the two are quite different, and the...

Problems solved by technology

On the one hand, there is a big difference in the taxonomic status and nutritional requirements of the two, and the shrimp feed cannot fully meet the nutritional needs for the survival and growth of the Taiwan loach; on the other hand, the shrimp feed is used as a submerged feed, and the feeding However, there is a risk of overfeeding, which can easily lead to deterioration of water quality. This is one of the reasons for the frequent occurrence of diseases and low survival rate of loach farming in Taiwan.

[0004] With the development of large-scale and intensive loach farming, in recent years, there have been phenomena such as seed degradation, eutrophication of water bodies, and frequent occurrence of diseases, resulting in a low success rate of loach farming in Taiwan.

Faced with diseases such as saprolegniasis, red fin disease, printing disease, and parasites that occurred during the loach breeding process in Taiwan, the farmers were troubled and panicked, and used a large amount of antibiotics, which not only produced drug resistance in the breeding objects, but also endangered food safety.
