Fermentation type feed capable of promoting metamorphosis of bullfrog tadpoles, and preparation method

Abstract

The invention discloses a fermentation type feed capable of promoting metamorphosis of bullfrog tadpoles. The feed comprises the following raw materials in parts by weight of 10-20 parts of fish meal,8-20 parts of chicken meat powder, 20-40 parts of dehulled soybean meal, 4-10 parts of peanut meal, 5-12 parts of corn protein powder, 8-16 parts of rice bran, 16-26 parts of flour, 0.5-2 parts of avitamin premix feed for frogs, 0.5-2 parts of a multiple-mineral premix feed for frogs and 0.2-0.4 part of 50% choline chloride, and further comprises fermentation components by weight of 1-3kg of lactic acid composite microbes, 1-3kg of spore composite microbes, 2-4kg of microzymes and 0.5-1kg of complex enzymes. The invention further discloses a preparation method of the fermentation type feed capable of promoting metamorphosis of bullfrog tadpoles. The metamorphosis cycle of the bullfrog tadpoles can be shortened through improving water quality and increasing the digestion and utilization rate, so that the metamorphosis rate of the tadpoles can be increased.

Description

technical field

[0001] The invention relates to the field of special feed for bullfrogs, in particular to a fermented feed capable of promoting metamorphosis of bullfrog tadpoles and a preparation method thereof. Background technique

[0002] The most famous edible frog in the world, the bullfrog is named for the bull-like voice of the male. Bullfrog is favored by people for its smooth and tender meat, delicious taste and rich nutrition. At present, the bullfrog breeding industry is developing rapidly, and the breeding areas are mainly concentrated in eastern Guangdong and southern Fujian. The scale of the bullfrog industry is huge, but the research on its nutritional requirements in the related feed industry mainly stays on the adult frogs after tadpole metamorphosis.

[0003] Under normal circumstances, bullfrog tadpoles begin to grow hindlimb buds after about 28 days after hatching, and then the hindlimbs gradually thicken and elongate to become well-developed hindlimbs...
