How to raise bullfrogs in cages? Mastering these key points is essential

The bullfrog has a large, plump body, grows rapidly, and has a high reproduction rate, making it currently the most suitable frog species in the world for use as meat. Since bullfrogs can only eat moving small animals, the feed problem has always been a major challenge in developing the bullfrog farming industry. Below is a brief introduction to bullfrog cage culture techniques for reference.

Cage culture involves placing bullfrogs in the rapid growth stage into specially made cages and using specially made feeding instruments to fill artificial compound feed into the frogs' stomachs. For the frog house, according to the breeder's economic conditions and farming scale, bullfrog cage culture housing can be divided into year-round production type and seasonal production type. The year-round production type frog house uses fully artificial control of environmental conditions to break the adverse effects of bullfrog hibernation and other unfavorable climate conditions on bullfrog growth. In terms of construction, it is necessary to consider both facilitating ventilation in summer and ensuring insulation and heating in winter. The seasonal production type frog house is only simply used during the frog's growing season, and can be a shade shed type, as long as it can prevent rain and sunlight. The cage equipment used for bullfrog cage culture consists of three parts: 1. support frame; 2. water trough; 3. frog cage. This structure is relatively simple, and the best production material is hard plastic. When conditions do not allow, wood can also be used for makeshift production.

Points to note:

1. The length of each frog cage should be determined according to the structure of the frog house, and the number of arranged tiers of each frog cage should be determined according to the spatial height of the frog house, ventilation conditions, and the height of the farming operator.

2. The frog cage in the water trough should preferably be slightly raised with small wooden blocks or other items, so that it is about 2-3 cm away from the bottom of the trough, while ensuring that the submerged depth of the frog cage is more than 3-5 cm.

3. Each small cage in each frog cage should be moderate in size, preferably able to hold 6-8 frogs of about 250 grams each. In this way, time can be saved during operation without affecting frog growth.

Feed preparation and processing requirements: The feed for cage-cultured bullfrogs must first meet the nutritional needs of bullfrogs, namely: about 35% crude protein, about 6% crude fat, of which more than 60% of the crude protein must come from animal protein or single-cell protein, and essential amino acids such as lysine and methionine should also be added to the feed.
