Astragalus feed types and feeding examples

First, the type of feed In general, the Astragalus is mainly fish animal feed, and require fresh feed, do not eat rotten animal feed. For artificial breeding, the feed for Astragalus should be based on animal feed, supplemented by plant feed.

1. Animal fresh feed: This type of feed mainly includes alfalfa, silkworm cocoon, fly cockroach, snail, cockroach and small fish shrimp. Wolfberry is the most favorite feed for Astragalus, with a dry body protein content of 61%, close to fish meal and cocoon. The common point of these feedstuffs is high protein content, rich nutrition, is conducive to the growth and development of Astragalus, and is the main body of feed for cage culture.

2, plant feed: Astragalus most of the plant food is forcing food. Its digestive characteristics are effective in the digestion of animal proteins, starches and fats, and almost no digestion of plant proteins and cellulose. In large-scale farming, certain plant feeds are required. This is because the quail in the artificial breeding environment is easier to get food than the individuals in the natural environment, and eats more and eats well. The input of a certain amount of cellulose-rich plant feed is beneficial to the promotion of intestinal peristalsis of the scutellaria baicalensis and increases the feeding intensity. . Usually a certain amount of wheat flour (also a binder), corn flour, bran, bran, and bean dregs are added to the compound feed.

3, artificial compound feed: feeding artificial compound feed is the trend of large-scale breeding. In recent years, some productive tests have also proved that formulated feeds are suitable for astragalus cultivation. In general, the protein content of formulated feeds is high, typically between 35% and 45% or even higher. At the same time require a certain degree of palatability. Of course, the proportion of animal feed in compound feeds still requires a large proportion.

4, other feed: open up the source of feed for Astragalus is the subject of large-scale conservation. According to the habit of Huangqi, animal waste can be used as a supplementary feed for artificial breeding, such as pigs, bovine lungs and other internal organs, but it requires a good freshness, and can not be rotted and deteriorated internal organs. There are also insects, some people use the black light above the cage to lure the insects to feed them. Feeding a certain amount of loach, snail, etc. in cages, and using certain techniques to allow them to breed small clams and snails into cages become live feeds for clams, which is a good measure for opening up feed sources.

Second, the Astragalus artificial compound feed feeding example

1. Zhejiang University used caged feed to feed cages, jaundice, and achieved good results. Their formulation consists of 60% of fishmeal, 22% of starch, 4% of yeast powder, 2% of wheat gluten, 4% of soybean meal, 1.2% of multivitamins, 1% of various minerals, 1% of additives, and 4.8% of others. The main nutritional indicators (%) of this formula are: crude protein 46.3, crude fat 5.36, crude fiber 0.87, crude ash 0.87, calcium 4.11, phosphorus 2.31. The composition of 10 essential amino acids is (%): lysine 1.37, methionine 1.04, histidine 0.91, arginine 3.21, phenylalanine 1.29, isoleucine 1.70, leucine 2.93, threonine 1.65, tryptophan 0.78, proline 2.61. 2 port cages through 120 For the day of feeding, the survival rate of scutellaria baicalensis was 90.5%, the feed coefficient was 1.27, the net profit was 2240 yuan, and the capital input-output ratio was 1:263.

2. The formula of Zhoutianyuan in Hubei Province is: bean cake powder 20%, bran (dry matter) 20%, cooked soybean powder 40%, blood meal 2.5%, corn gluten 1.5%, calcium dihydrogen phosphate 3%, adhesive agent 5% .
