Embodiment 1

[0016] Tilapia overwintering feed, its basic formula is mainly the following raw materials by weight percentage:

[0017] Soybean Meal 20%

[0018] Fish Meal 5%

[0019] 20% rapeseed meal, 13% cottonseed meal, 2.5% rice bran meal

[0020] Wheat Flour 33%

[0021] Fish Oil 3.5%

[0022] Vitamin E 0.03%.

[0023] The remaining 2.97% are additives, including 1% premix, 1.67% calcium hydrogen phosphate and 0.3% table salt.

[0024] According to the above formula, adopt the following method to prepare tilapia overwintering feed: firstly crush soybean meal, fish meal, rapeseed meal, cottonseed meal and rice bran meal respectively, then take wheat flour and mix the crushed raw materials, then add fish oil, vitamin E and additives, etc. Further preparation and mixing, tempering and granulation are obtained.

[0025] The crude protein, crude fat, ash and moisture content of the obtained feed were determined to be 30%, 5%, 7.5% and 10% respectively.

Embodiment 2

[0027] Tilapia overwintering feed, its basic formula is mainly the following raw materials by weight percentage:

[0028] Soybean Meal 31%

[0029] Fish Meal 3%

[0030] 8% rapeseed meal, 7% rice bran meal, 8.5% peanut meal

[0031] Wheat Flour 35%

[0032] Fish Oil 2%

[0033] Vitamin E 0.04%

[0034] The remaining 5.46% is phospholipid feed (2.2%) and additives (3.26%), and additives include 1% premix, 1.96% calcium hydrogen phosphate and 0.3% salt.

[0035] The preparation method is the same as in Example 1.

[0036] The crude protein, crude fat, ash and moisture content of the obtained feed were determined to be 28.5%, 5%, 7% and 9.8%, respectively.

Embodiment 3

[0038] Tilapia overwintering feed, its basic formula is mainly the following raw materials by weight percentage:

[0039] soybean meal 25%

[0040] Fishmeal 2%

[0041] 17% rapeseed meal, 18% rice bran meal

[0042] Wheat Flour 28%

[0043] Fish Oil 5.0%

[0044] Vitamin E 0.04%

[0045] The remaining 4.96% is phospholipid feed (1.9%) and additives (3.06%), and additives include 1% premix, 1.76% calcium hydrogen phosphate and 0.3% salt.

[0046] The preparation method is the same as in Example 1.

[0047] The crude protein, crude fat, ash and moisture content of the obtained feed were determined to be 25%, 7%, 8% and 10.5% respectively.

Abstract

The invention discloses a Tilapia mossambica overwintering feed. The feed is prepared from the following raw materials in percentage by weight: 20-40% of bean pulp, 0-5% of fish meal, 15-40% of miscellaneous meal, 20-35% of wheat flour, 2-5% of fish oil and 0.03-0.05% of Vitamin E, wherein the miscellaneous meal is one or more of rapeseed meal, cotton seed meal, peanut meal and rice bran meal. The crude protein content and crude fat content of the feed are 25-30% and 5-7% respectively. In the invention, the fish oil containing polyunsaturated fatty acids is used to improve the fat level of the complete feed, thus providing sufficient energy for the Tilapia mossambica; at the same time, the Vitamin E is added properly, thus strengthening ingestion of the vitamin, improving nutrient balance of the Tilapia mossambica, improving the immunity of the Tilapia mossambica, and intensifying the soma and cold and disease resistances of the Tilapia mossambica, thereby ensuring that the Tilapia mossambicas successfully live through the winter and improving the security coefficient of overwintering cultivation.

Description

technical field [0001] The invention relates to the field of tilapia culture, in particular to a tilapia overwintering feed. Background technique [0002] Tilapia (Oreochromis niloticus x O.aureus) belongs to the genus Tilapia of the eel family of Perciformes. It is the main economic fish in Africa's freshwater and brackish waters, and it is promoted all over the world as a good breeding object. However, tilapia is a warm-water fish that is not resistant to low and high temperatures. The survival temperature range is 12-35°C, and the optimum growth temperature is 24°C-32°C. Stop feeding when the water temperature drops to 14°C, and it may die below 12°C. . Guangxi, Guangdong is a large province for tilapia farming. The temperature in winter will drop to around 5°C and stay there for 3-4 months. The rain, snow and freezing disaster at the beginning of the year brought huge losses to the southern tilapia farming industry. Therefore, overwintering and conservation of specie...
