Problems solved by technology

The nutrition of these feeds is single, which easily leads to low disease resistance, low metamorphosis rate and high mortality of tadpoles; the nutritional status of tadpoles is directly related to the physique of juvenile frogs and adult frogs, which makes it difficult to expand the breeding scale of spiny-breasted frogs and reduce economic benefits. Difficult to climb significantly

Embodiment 1

[0027] Embodiment 1. Feed for Rana spinosa tadpoles, consisting of the following components by weight: pre-feed 8.3%, fish meal 34.9%, and flour 56.8%.

[0028] The above-mentioned pre-feed can be selected from Hengyuan Tadpole Compound Feed (3600 Tadpole Powder#) produced by Guangdong Hengyuan Feed Industry Co., Ltd., and the product standard number is Q / GDHY 01-2014.

[0029] The preparation method is as follows:

[0030] Grind the above-mentioned raw materials into powder and repeat the screening for 3 times with an 80-mesh fine sieve with an aperture of 0.2mm, and then take the corresponding portion of screened fish meal, flour and wheat bran according to the above ratio and mix them evenly to obtain spinosa tadpoles feed.

[0031] After testing, the crude protein content of the obtained Rana spinosa tadpole feed is about 30%, the crude fat content is about 5%, and the ratio of crude protein content to crude fat content is 6:1.

Abstract

The invention provides a spiny-breasted tadpole feed. The crude protein content of the spiny-breasted tadpole feed is 28-32%, the crude fat content is 4-6%, and the ratio of the crude protein content to the crude fat content is 5.8-6.2:1 . The invention also provides a method for preparing a spiny-breasted tadpole feed and a feeding method using the spiny-breasted tadpole feed. The spiny-breasted tadpole feed prepared by the present invention is fed according to the principle of "four fixed" feeding, which can make spiny-breasted tadpoles accumulate energy in the body faster, and make the raised spiny-breasted tadpoles more effective than the raised ones. The metamorphosis period entered in the 8th week, and the average body weight of Rana spinosa tadpoles could reach 1.488g and the average body length could reach 4.543cm in the 8th week, and the survival rate and metamorphosis rate could be kept high.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a spinosa tadpole feed and a preparation method thereof. Background technique [0002] Rana spinosa (Ranaspinosa David.), commonly known as stone frog, rock chicken or rock frog, belongs to Amphibians, Anura, Ranaidae, and Rana. The spiny-breasted frog is used to living in higher mountain forests and streams; it is common in southern China and Vietnam, with southern China as the main distribution area. Rana spinosa is delicate in meat, rich in nutrition, and has both economic value and medicinal value. It is one of the important farmed frogs in China. The research and product development of Rana spinosa are also in full swing. However, due to over-fishing by humans, the population of spiny-breasted frogs has plummeted, coupled with environmental pollution and unreasonable land development, the habitat of spiny-breasted frogs has been threatened. Therefore, it is urgent to realiz...
