Embodiment Construction

[0011] Below in conjunction with this embodiment the present invention is further described:

[0012] Feeding methods to improve the survival rate and oil production rate of Rana:

[0013] 1. Place the fertilized egg mass for about 5 days to hatch. During this period, no feeding is required. After the tadpoles hatch, they first eat the egg membrane that encloses the eggs. The egg membrane eats for 7 to 10 days. Soybean milk is used as the bait, and the bait is fed once a day; the cooked egg yolk is wrapped with two layers of gauze, and slowly shaken in the pool water, the egg yolk will dissolve in the water, and the tadpoles can eat freely. The protein content in the feed should be gradually increased. After starting to feed the bait, the water should be changed frequently and disinfected regularly.

[0014] 2. After about 30 days of breeding, the tadpoles begin to enter the metamorphosis period. The young frogs that have just metamorphosed do not need to be fed. After the ta...

Abstract

The feeding method for improving the survival rate and the oil extraction rate of wood frogs comprises the following steps that after tadpoles are hatched, the tadpoles are fed by egg membranes containing eggs for 7 to 9 days, and after the egg membranes are eaten up, the tadpoles are fed by bait as which cooked egg yolk or soybean milk serves, and the tadpoles are fed by the bait one time every day; after the tail of each froglet is completely absorbed, the froglets are fed by small flour weevils with the length ranging from 0.6cm to 0.8cm, a black light lamp is used for luring natural insects to be auxiliary bait, and the froglets are fed one time in the morning and one time in the evening; after 10-15 days, the froglets are fed by flour weevils with the length ranging from 1cm to 1.2cm and are fed twice every day; after 3 months, the frogs are fed by flour weevils with the length ranging from 1.5cm to 2cm and are fed twice to three times every day. By means of the method, the survival rate of the wood frogs is improved to 90%, and the oil extraction rate is increased by 20% on the existing basis.

Description

Background technique [0001] The invention relates to a feeding method, in particular to a feeding method for improving the survival rate and oil yield rate of wood frogs. Background technique [0002] In recent years, every time the frog hatches and metamorphoses, severe drought often occurs, the temperature is high, the ground is dry and hot, and there is little humid environment even under the fallen leaves of the forest. As a result, free-range forest frogs (artificial hatching and free uphill breeding) metamorphosis landed on the shore, without protection from a humid environment, and most of them died due to high temperature, drought, and drying, causing a serious decline in the output of forest frogs. The spring drought has caused insurmountable obstacles to the development of Rana. For example, in the severe drought in the spring of 1997, young frogs could not find a suitable living environment after landing, and most of them died in the sun. Many frog farmers report...
