Problems solved by technology

However, unlike other freshwater perch (such as gem perch) and sea bass (barramundi), California perch is prone to the following problems when using compound feed: (1) California perch is less fond of compound feed than chilled bait; (2) California perch The utilization rate of carbohydrates is not high, but due to the limitation of current domestic production equipment and technology, the level of feed carbohydrates is difficult to reduce
However, there is no special compound premix specifically for California perch feed on the market at present, and it is often replaced by a general premix for common carnivorous fish, which does not meet the nutritional needs of California perch and seriously affects the use of compound feed

[0022] Yeast extract contains 50 grams of nucleotides and 88 grams of free amino acids based on 10...

Embodiment 2

[0029] The preparation method of the compound premix of Example 2 is the same as that of Example 1, and it is added to the feed formula shown in Table 1 (feed formula of Example 2) to make the feed. From June 4, 2009, premixed The feed was used as a control. California perch with an initial weight of 155 grams was fed for 151 days in Shunde District, Foshan City, Guangdong Province. Each feed was divided into two ponds for breeding. The detection data at the beginning of the catch are shown in Table 3:

Abstract

The invention discloses a special compound premix for Micropterus salmoides, belonging to the field of aquatic product feed and comprising compound vitamin, a complex mineral element, a yeast extract, chromium picolinate premix, bile acid premix and defatted rice bran. The invention can meet the nutrition requirements for healthy and rapid growth of the Micropterus salmoides. Compared with a control group, the use of the compound feed of the Micropterus salmoides can be prolonged to the adult fish period; the rate of body weight gain of the Micropterus salmoides is increased by 10-20 percent, and the bait coefficient is reduced by 10-15 percent; the liver has bright red color and is not swelling; the fat content is obviously reduced; the fish morbidity is obviously reduced; and the oxygen deficit resistance and the transport resistance are obviously increased. The special compound premix does not contain any antibiotic or forbidden drug and meets the national feed safety regulation. The raw material is easy to purchase and the production and the quality are easy to control.

Description

technical field [0001] The invention relates to an aquatic compound premix, in particular to a special compound premix for California perch. It belongs to the field of aquatic feed. Background technique [0002] California perch, also known as largemouth bass, belongs to the family Centrarchidae of the order Perciformes. It originated in California, USA, and was introduced to China in the early 1980s. California perch has the advantages of fast growth, less disease, low temperature resistance, less thorns, delicious taste and rich nutrition, and is very popular in the market. In recent years, California perch has become one of the important freshwater aquaculture species in my country. However, in recent years, problems such as environmental pollution and frequent occurrence of diseases caused by the mode of feeding chilled fish in my country have affected the sustainable development of the California perch aquaculture industry. Gradually popularize and apply in production...
