Embodiment 1

[0026] Example 1 (preparation of feed for intensively cultured tilapia in ponds):

[0027] A compound feed suitable for intensive cultivation of tilapia in ponds, which consists of the following raw materials by mass percentage:

[0028]

[0029]

[0030] In this example, the protein content of the feed was 28.9%, and the fat content was 6.1%.

[0031] A kind of preparation method of feed suitable for intensive cultivation of tilapia in ponds, its steps are:

[0032] A first weigh soybean meal, full-fat puffed soybean, rapeseed meal, cottonseed meal, rice bran and secondary powder according to a certain mass percentage;

[0033] B is evenly mixed and then pulverized by a pulverizer, so that all components pass through a 20 or 25 or 30 or 35 or 40 mesh sieve;

[0034] C. Weigh the remaining raw materials according to a certain mass percentage, and mix them with the raw materials of step B, and mix them thoroughly with a mixer (CV≦5%);

[0035] D. Move the mixed materia...

Abstract

The invention discloses a type of feed applicable for tilapias intensively cultured in a pond and a preparation method thereof. The feed contains the following ingredients by mass percent: soybean pulp, whole milk puffed soybean, dried blood, rapeseed meal, cottonseed meal, soybeam oil, wheat middling, rice bran, mineral gunk, vitamin gunk, monocalcium phosphate, zeolite powder, bentonite, choline chloride, vitamin C and vitamin E. The preparation method includes the steps of: weighing soybean pulp, whole milk puffed soybean, rapeseed meal and the like according to the mass percent, mixing the mixture to be even, grinding the mixture, mixing the ground mixture with the rest raw materials, tempering and pelleting, drying, removing the powder, inspecting whether the feed is qualified and finally packaging. The raw materials of the feed are common and are low in costs, and the preparation method is simple and reliable; the raw materials are reasonably proportioned; with the improved formulas of the vitamin gunk and the mineral gunk, the feed better satisfies the physiological needs of tilapias intensively cultured in the pond; and after the tilapias with weight of about 180g are fed with the feed disclosed by the invention for two months, the feed coefficient can reach about1.3 and the specific growth rate reaches about 1.9%/d.

Description

technical field [0001] The invention belongs to the field of aquaculture feed, in particular to a feed suitable for intensive tilapia culture in ponds, and also relates to a preparation method for a feed suitable for intensive tilapia culture in ponds. Background technique [0002] Tilapia is a small and medium-sized fish, commonly known as African crucian carp. It is a high-quality fish recommended by the United Nations Food and Agriculture Organization (FAO) to promote aquaculture to the world. It is known as one of the main sources of animal protein in the future. Since 2006, the annual aquaculture production in mainland China has exceeded 1 million tons, ranking first in the world. The cultivation methods of tilapia mainly include pond cultivation and cage cultivation, and pond intensive cultivation is one of the main methods of pond cultivation. More than ten acres) of water, mainly tilapia, with a small amount of other feeding and filter-feeding fish, feeding high-qua...
