Several key points of caged bullfrog

Bullfrog is large, fat, rapid growth and high reproduction rate, which is the most suitable for carnivorous frogs in the world. because bullfrogs are small animals that can only feed, the feed problem has always been a difficult problem in the development of bullfrog breeding industry. the following is a brief introduction of bullfrog cage culture technology for reference.

Cage raising is to put the bullfrog in the rapid growth stage in a special cage and use the special feeding equipment to fill the artificial formula feed into the frog stomach. According to the economic conditions and scale of breeders, bullfrog caged houses can be divided into annual production type and seasonal production type. The annual production frog house adopts fully artificial control of environmental conditions to break the adverse effects of bullfrog hibernation and other adverse climatic conditions on the growth of bullfrog. In architecture, it is necessary to consider that summer is conducive to ventilation, but also to ensure heat preservation and heating in winter. The frog house of the seasonal production type is simply used in the frog growing season, and it can be a cool shed type, as long as it is protected from rain and sunscreen. The cage used for raising bullfrogs consists of three parts: 1, bracket; 2, sink; 3, frog cage. This kind of structure is relatively simple, the production material had better be hard plastic, when there is no condition, it can also be made simply with wood.

It should be noted that:

1. The length of each frog cage should be determined by the structure of the frog house, and the number of layers of each frog cage should be determined by the space height of the frog house, the ventilation conditions and the height of the breeding operator.

2. It is best to cushion the frog cage in the sink with small wooden blocks or other objects to make it leave the bottom of the trough about 2mi 3cm. At the same time, make sure that the immersion depth of the frog cage is more than 3Mel 5cm.

3. Each small cage in each frog cage should be of moderate size, so that it is suitable to hold 8 frogs of about 250 grams. In this way, the operation can save time without affecting the growth of the frog.

Feed preparation and processing requires that the feed of caged bullfrogs must first meet the nutritional needs of bullfrogs, that is, about 35% of crude protein and 6% of crude fat, of which more than 60% of crude protein must come from animal protein or single-cell protein. and essential amino acids such as lysine and methionine should be added to the feed.
