Problems solved by technology

This breeding mode will cause the frogs to lack activity and poor physical function. Coupled with the high nutrition of the artificial feed, it will lead to overnutrition in the frog body, high metabolic pressure, and common symptoms such as fatty liver.
In this way, compared with wild frogs, farmed frogs will have poorer meat quality and nutrition, lower immunity, and are prone to some diseases such as "tilt head disease", causing a lot of losses to farmers

Embodiment 1

[0033] Application of a black-spotted frog feed containing mature larvae of soldier flies in artificial breeding of black-spotted frogs:

[0034] Control group feed 1:

[0035] Raw material parts by weight

[0036] Compound feed for frogs 100

[0037] Soldier fly mature larvae 0 (by dry weight)

[0038] The feed of the control group contained, per 100g: crude protein 40.0g, crude fat 3.0g, lysine 1.80g, crude ash ≤ 17.0g. The same below.

[0039] The feed of this embodiment is used to cultivate black-spotted frogs with an average body weight of 25.0g in an open-air experimental pond of 1m × 4m in the Fuyuan black-spotted frog breeding base in Anshan, Wuhan. Each experimental pond contains 1㎡ and a water area about 1m deep. , breeding 100 frogs, and setting three repetitions.

[0040] Feed twice a day (at 07:00 and 17:00) every morning and evening, and the feeding amount is 2% of the body weight, and it is adjusted according to the feeding and growth conditions. Before fe...

Embodiment 2

[0043] Application of a black-spotted frog feed containing mature larvae of soldier flies in artificial breeding of black-spotted frogs:

[0044] A black-spotted frog feed containing mature soldier fly larvae:

[0045] Component Parts by weight

[0046] Compound feed for frogs 75

[0047] Soldier fly mature larvae 25 (by dry weight)

[0048] After mixing the above-mentioned compound feed for frogs with mature soldier fly larvae in proportion, a black-spotted frog feed containing mature soldier fly larvae is obtained. The prepared black-spotted frog feed contains: crude protein 40.5-41.3 per 100g , crude fat 10.1-10.95, lysine 2.20, crude ash 14.8-16.4.

[0049] Breeding and feeding methods are the same as in Example 1.

Embodiment 3

[0051] Application of a black-spotted frog feed containing mature larvae of soldier flies in artificial breeding of black-spotted frogs:

[0052] A black-spotted frog feed containing mature soldier fly larvae:

[0053] Component Parts by weight

[0054] Compound feed for frogs 50

[0055] Soldier Fly mature larvae 50 (by dry weight)

[0056] The prepared black-spotted frog feed contains, per 100 g: 41.1-42.6 crude protein, 17.2-18.9 crude fat, 2.6 lysine, and 12.7-15.8 crude ash.

[0057] Breeding and feeding methods are the same as in Example 1.

Abstract

The invention discloses a pelophylax nigromaculatus feed containing hermertia illucens mature larvae and applications of the feed. Hermertia illucens mature larvae match with an artificial feed according to a ratio of 1:1 so as to obtain the feed. The feed contains about 41.1-42.6% of crude protein, about 17.2-18.9% of crude fat, about 2.6% of lysine and about 12.7-15.8% of crude ash. In the invention, the hermertia illucens mature larvae are used as live bait to replace part of artificial feed, and the novel pelophylax nigromaculatus feed is obtained through matching. Under general culture conditions, the feed can effectively provide all nutrients required by pelophylax nigromaculatus, effectively ensure the survival rate and the weight-gain rate of the pelophylax nigromaculatus, and significantly improve the weight-gain rate, specific growth rate and activity degree. The condition factor, the muscle crude fat content and the muscle crude protein content of the pelophylax nigromaculatus are all superior to that of pelophylax nigromaculatus fed with pure artificial feeds.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and specifically relates to a black-spotted frog feed containing mature soldier fly larvae and its application. Using the feed provided by the invention to feed the black-spotted frog can make the artificially cultivated black-spotted frog have a higher weight gain rate, specific growth rate and feed efficiency. Background technique [0002] Black-spotted frog (Pelophylax nigromaculatus), the scientific name of which is Pelophylax nigromaculatus, belongs to Anura, Ranaidae, and belongs to the genus Pelophylax nigromaculatus. It is widely distributed in all provinces and regions of my country except Hainan, Taiwan, and Yunnan. [0003] Black-spotted frog adult frogs generally have a body length of about 7-8 cm, a weight of about 50-60 grams, and a maximum of about 100 grams. Female frogs of the same age are larger than male frogs. During the tadpole period, the body is fat, green with small irregular ...
