Abstract

The granulated feed is produced with feed material and special Tilapia mossambica additive through mixing and pressing into 2.5-4 mm size grains. Being nutritious and with high, 1 to 1.0-1.3, feed coefficient, the said feed can raise Tilapia mossambica with meat as delicious as that of wild one. The said feed is also suitable for carp, crucian carp and butterfish.

Description

Granulated feed for pisciculture of Tilapia mossambica and method for making thereof

The present invention belongs to the fish meal technical field, particularly a kind of pisciculture of Tilapia mossambica feed and method for making thereof.

At present, China's aquaculture fishery is developing rapidly.Past, the sort of old tradition aquaculture model based on " four large Chinese carps " reduced gradually.And breed such as pond, net cage, warm water are all so that " the high yielding culture pattern of the raising together with of name, excellent, special cultivation, monoculture is in rapid rise, and particularly fast to grow, nutritious, the meat delicate flavour U.S. and delicate of Australia Buddhist nun Tilapia mossambica wins the people's favor.But the fish meal that present many feed producer produces owing to the prescription that can not find is of poor quality, feed coefficient is high, the feed cycle is long, though the fish meal crude protein content of some manufacturer production is high, but nutrition is unbalanced, causes waste, incidence of disease height, the survival rate of bait low.In order to satisfy people's demand growing to fish, in order to contribute to " vegetables-basket " engineering, at the problems referred to above, special proposition technical scheme of the present invention.

The present invention seeks to: provide a kind of nutrient balance, prescription rationally, price is suitable, feed coefficient is low, fast growth, tilapia feed that the incidence of disease is low, to reduce feeding cost, to shorten growth cycle, quickens " vegetables-basket " engineering development.

Technical scheme of the present invention is achieved in that

First scheme: fish meal 10～20%, dregs of beans 10～20%, corn 5～15%, peanut cake 10～20%, inferior powder 20～30%, cotton dregs 5～15%, yeast 3～6%, choline 0.5%, mineral additive 2%, multivitamin ABCDE0.3% and methionine, lysine, attractant 1～2%.

Alternative plan: with the inferior powder 20～30% of flour 20～30% replacements first scheme, with the cotton dregs 5～15% that the dish dregs of rice 5～15% replace in first scheme, all the other components are identical.

Third party's case: with the inferior powder 20～30% of wheat bran 10% and time powder 10～20% replacements first scheme, all the other components are identical.

As follows to above-mentioned batching adopting process process:

1. earlier dregs of beans, corn, peanut cake, cotton dregs (or dish dregs of rice) are pulverized its fineness≤1.5mm respectively.

2. by above-mentioned formula rate respectively above-mentioned raw materials is weighed the metering after, stir mixing through agitator, its uniformity is below 5.3. above-mentioned compound is entered a steam material machine granulation, grain is through being 2.5～3.5mm, and drying through after the assay was approved, is packed, dispatched from the factory after classifying screen screens out powder.

Above-mentioned feed is particularly suitable for tilapia mossambica food usefulness, and also suitable carp, crucian, butterfish eat.

The beneficial effect that adopts feed of the present invention compared with prior art to be had:

1. edible this feed fast growth of fry: Tilapia mossambica seed then only needs can reach in 3～4 months listing specification (400～500 gram) and makes tradition only support one in 1 year to make fish, becomes 1 year and can support two, three to make fish.

2. feed coefficient minimum (1.0～1.3), economic benefit is the highest, reach leading domestic level: long only 1 jin of fish only needs 1 jin of feed, the used feed cost of 1 jin of fish of every production only needs 1.6～2.0 yuan, add the aquaculture management technology of science, can support 2～3 every year and make, whenever make 1500～2500 jin of per mu yields, by 5 yuan of calculating per jin, every mu of annual net profit can reach 10,000～20,000 yuan.

3. the fish incidence of disease reduces greatly: because the compound feed used for fish comprehensive nutrition is furnished with preventive medicine at susceptible disease season, can improve the fish motility rate greatly, survival rate can reach more than 95%.

4. fish delicious meat, high resilience can compare favourably with wild Tilapia mossambica fully.

The following describes most preferred embodiment of the present invention:

Example 1: adopt fish meal 10%, dregs of beans 20%, corn flour 5%, peanut cake 20%, cotton dregs 5%, inferior powder 30%, yeast 6%, choline 0.5%, mineral additive 2%, multivitamin 0.3%, lysine, methionine, attractant 1.2%, can become the edible feed of Tilapia mossambica class through above-mentioned processes, be particularly suitable for middle adult fish.

Example 2: adopt fish meal 15%, dregs of beans 15%, corn flour 12%, peanut cake 15%, inferior powder 23%, cotton dregs 10%, yeast 6%, choline 0.5%, mineral additive 2%, multivitamin 0.3%, lysine, methionine, attractant 1.2%, after above-mentioned processes, can become the edible feed of fish, be particularly suitable for medium tilapia mossambica food and use.

Example 3: adopt fish meal 20%, dregs of beans 10%, corn flour 15%, peanut cake 10%, the dish dregs of rice 15%, inferior powder 20%, yeast 6%, choline 0.5%, mineral additive 2%, multivitamin 0.3%, lysine, methionine, attractant 1.2%, after above-mentioned processes, can become the edible feed of fish, be particularly suitable for the Tilapia mossambica fry and eat.

Claims
