Problems solved by technology

[0008] (1) The food attractant is not strong, resulting in poor palatability and slow growth rate;
[0009] (2) The phenomenon of "discoloration in twos and twos and deformation in fives and twos" is prominent;
[0010] California bass likes to eat live bait, and they compete fiercely when eating. Uneven feeding can easily lead to problems such as large individual differences, uneven specifications of finished fish, and low commodity rate.
The above-mentioned floating feed cannot simulate the dynamic and slow sinking of live bait, and cannot achieve the goal of three-dimensional feeding; a considerable part of the floating feed does not become the food of California perch, which not only causes waste of resources, but also pollutes water bodies
[0011] (3) Due to the limitation of production equipment and production process, if the content of carbohydrates is reduced and the content of crude fat is increased, floating feed cannot be made
[0012] However, long-term consumption of high-carbohydrate (i.e. high-sugar) feed can easily lead to pathological changes in the liver and gallbladder in the late growth period, forming fatty liver, resulting in a significant slowdown in growth
Therefore, it is still impossible to realize the full feeding of compound feed in the artificial breeding of California sea bass

Embodiment 1

[0070] Embodiment 1, a low-sugar, high-fat, slow-sinking type California perch extruded compound pellet feed, the following steps are carried out in sequence:

[0071] 1. Ingredients:

[0072] Weigh 55% of fish meal, 8% of by-products of shrimp / crab processing, 8% of soybean meal, 5% of beer yeast, 1.7% of calcium dihydrogen phosphate, 3.5% of vitamin and mineral premix, and 8% of high-gluten flour , lecithin oil 2%, fish oil 8%, capillary 0.4%, apocynum 0.2%, Bupleurum 0.2% as the basic formula.

[0073] Add 0.1% of bamboo leaf flavonoids accounting for the total weight of the basic formula to the above basic formula.

[0074] It is known through routine testing that carbohydrates account for 10% (weight ratio) and crude fat accounts for 18% (weight ratio) in the basic formula of the California perch feed.

[0075] 2. Crushing:

[0076] Fish meal, shrimp / crab processing by-products, soybean meal, brewer's yeast, calcium dihydrogen phosphate, vitamin and mineral premix, hig...

Embodiment 2

[0091] Example 2, a low-sugar, high-fat, slow-sinking California perch extruded compound pellet feed

[0092] The additive amount of bamboo leaf flavonoids was increased to 0.2% of the total weight of the basic formula, and the basic formula was the same as in Example 1. Feed processing technology is also identical with embodiment 1.

[0093] After adding bamboo leaf flavonoids, the oxidation of lipids in the feed was effectively protected. Taking the pellet feed without bamboo leaf flavonoids as a comparison (basic formula and production process are equal), the acid value (from 4.34mg / g to 4.38mg / g) and iodine value (112.2g / 100g rises to 112.9g / 100g) index, the shelf life is increased to 60 days from 30 days, namely adding 0.2% bamboo leaf flavonoids doubles the shelf life of the feed.

[0094] Experiment 1, breeding effect

[0095] Since June 1, 2009, a 5-month breeding experiment has been carried out at the California Perch Breeding Demonstration Base in Zhongguan Town,...

Abstract

The invention discloses a low-sugar, high-fat and slow-precipitation type micropterus salmoides expanded formulated pellet feed. A basic prescription of the pellet feed comprises 9-15 percent of carbohydrate and 8-22 percent of grease; the bamboo-leave flavone which accounts for 0.05-0.5 percent of the total weight of the basic prescription is added into the basic prescription of the pellet feed;and the volume mass of the pellet feed is 380-420kg / m<3>. The invention also discloses a preparation method of the pellet feed, which comprises the steps of dispensing, pulverizing, mixing, tempering, expanding, granulating, drying, and the like. The pellet feed has the characteristics of simple preparation, balanced nutrition and meeting the growth requirement of a micropterus salmoides.

Description

technical field [0001] The invention belongs to the technical field of perch feed, and in particular relates to the formulation and manufacturing technology of a low-sugar, high-fat, slow-sinking California perch puffed compound pellet feed fortified with bamboo leaf flavonoids. Background technique [0002] California perch, also known as largemouth bass (Micopterus salmoides), belongs to the order Perciformes, the family Sunfish, and the genus Black Bass. It is native to North America and is a wide-temperature carnivorous fish. It was introduced into my country in the early 1980s. California perch is a medium-to-high-end cultured species, and it is part of the "Vegetable Basket" project. In recent years, the sales volume of California perch freshwater famous and high-quality species has approached the four major fishes, and a large number of them are exported. California bass can be reared in polyculture or monoculture with domestic fish in ponds, or intensively in clear w...
