Description

Toad stage puffing bait formula and preparation method thereof
Technical Field
The invention relates to the technical field of feed processing, in particular to a toad stage puffed bait formula and a preparation method thereof.
Background
Toads belong to the commonly known toads, are the terminales and the toad family, are wild animals widely distributed in China, have a long development history, and have medical value records in many medical writings of China. Modern researches prove that the white serous fluid secreted by the retroauricular glands and the skin glands of the toads, namely the toad venom, contains various bioactive components, has a plurality of efficacies of detoxifying, detumescence, pain relieving, heart strengthening, diuresis, cancer resistance, anesthesia, radiation resistance and the like, and is commonly used for treating diseases such as human heart failure, stomatitis, pharyngolaryngitis, sore throat, skin cancer and the like; periostracum Cicadae, which is the cuticle removed by Bufo siccus, has good curative effect on chronic hepatitis and various cancers; the toad meat is cold in nature and pungent in flavor, can remove toxin, cure sore and eliminate stagnation, and is used for treating diseases such as leukemia, liver cirrhosis and the like; the toad skin, the toad gall, the toad liver and the like are all medicinal materials, so the toad is an amphibious economic animal with high medicinal value and is treasure on the whole body.
In recent years, the number of wild toads is suddenly reduced due to environmental pollution, habitat loss and the influence of natural enemies and human factors, the number of ecological breeding is far from meeting the market demand at present, and the intensive breeding of the toads is an inevitable trend along with the rigid demand of the medical market. The feed composition of the toads in the tadpole stage is universal with the feed formula of frogs such as wood frogs in the tadpole stage, and the metamorphosis toads only eat active insects, so that the intensive feeding scale is limited. Because the toads are omnivorous frogs and mainly eat lepidoptera, coleoptera, hymenoptera and other insects, earthworms, snails, fly maggots and the like in the nature, the current artificial breeding mainly adopts the matching of bait to be pressed into granular feed, a vibrating feeder is adopted to ensure that the bait is mobilized, and the bait movement causes the toads to feel miseat. At present, baits used by young and adult toads are non-expanded granular materials, do not have the specificity of toad feed, lack of food calling factors, have poor palatability, cause low food taking rate of the toads, and cause the phenomena of malnutrition, high mortality and the like caused by the phenomenon that the toads are swallowed in the mouth but are pulled out of the mouth by forefinger. The development of intensive scale toad breeding is severely limited by the influence of a plurality of factors such as the palatability, the nutrition proportion, the shape, the physicochemical property, the mobilization effect, the feeding promoting factors, the artificial bait blank of young toads and the like of the bait.
