Breeding method for increasing condition factor of froglets of rana nigromaculata

Abstract

The invention belongs to the technical field of frog breeding, and particularly relates to a breeding method for increasing the condition factor of froglets of rana nigromaculata. The method comprisesthe following specific steps that (1) the depth of a breeding pond is established to be 72-78 cm at the beginning of March, potamogeton malaianus is evenly planted at the bottom of the pond, the froglets of rana nigromaculata are put into the breeding pond at the beginning of April, and light-filling illumination treatment is conducted by using green light every day; (2) frog feed is put four times every day, and the feeding amount every time is same, wherein the frog feed is prepared from sorghum rice, small glutinous millet, grape skin residues, yellow mealworm, pig livers, barley leaves, cactus, pine pollen, steviol glycoside, Chinese bushcherry seed extract, mulberry polysaccharide and bacillus natto; an excellent living environment is provided for the growth of the froglets of rana nigromaculata, the capabilities of absorbing and digesting nutrients and resisting harmful bacteria are improved, the robust growth of the frog bodies is effectively promoted, the frogs are fat, big and strong, the muscle content is high, and the conversion synthesis and accumulation of protein, iron and selenium can also be promoted.

Description

technical field [0001] The invention belongs to the technical field of frog breeding, in particular to a breeding method for improving the fatness of young black-spotted frogs. Background technique [0002] The black-spotted frog, the scientific name of the black-spotted sidefold frog, belongs to the chordate phylum Amphibian Anura Ranaidae, and is a common frog in the wild in my country. It is generally referred to as a frog together with the tiger frog and the Chinese forest frog; Animals are favored by consumers and farmers because of their delicious taste and the use of medicine, food and supplements. Due to the large market demand in recent years, most farmers adopt high-density breeding in small ponds and use artificial feed in large quantities. This breeding mode will cause the frogs to lack activity and have poor physical function. Coupled with the high nutrition of the current artificial feed, it will lead to overnutrition in the frog body, high metabolic pressure, an...

[0002] The black-spotted frog, the scientific name of the black-spotted sidefold frog, belongs to the chordate phylum Amphibian Anura Ranaidae, and is a common frog in the wild in my country. It is generally referred to as a frog together with the tiger frog and the Chinese forest frog; Animals are favored by consumers and farmers because of their delicious taste and the use of medicine, food and supplements. Due to the large market demand in recent years, most farmers adopt high-density breeding in small ponds and use artificial feed in large quantities. This breeding mode will cause the frogs to lack activity and have poor physical function. Coupled with the high nutrition of the current artificial feed, it will lead to overnutrition in the frog body, high metabolic pressure, and common symptoms such as fatty liver. Compared with frogs, the meat quality and nutrition will be worse, and the immunity will be lower, which will lead to unsatisfactory plumpness of black-spotted frogs and cause certain economic losses to farmers; in recent years, many scientific researchers have used live insects to directly or indirectly replace Artificial feed is used to raise frogs, but the cost of breeding is too high, and the nutrient conversion rate is not ideal
