Compound feed capable of enhancing reproductive capacity of parent dace

Abstract

The invention discloses a compound feed capable of enhancing reproductive capacity of a parent dace and aims at providing the compound feed capable of enhancing the reproductive capacity of the parent dace, the gonad index of the dace, the egg diameter, the egg laying amount, the fertilization rate of the parent dace, and the fry hatching-out rate. According to the technical scheme, the feed consists of basic ingredients and a Chinese herb medicine additive according to a mass ratio of (99.5-99.9):(0.1-0.5), wherein the basic ingredients include 20-30 parts of wheat, 4-6 parts of rice bran, 6-8 parts of vinasse, 20-30 parts of rapeseed meal, 15-20 parts of bean meal, 10-18 parts of a maize gluten feed, 2.5-4 parts of bean oil, 1 part of monocalcium phosphate, 1 part of bentonite, 0.5 part of multi-vitamin and 1.0 part of complex mineral matter; and the Chinese herb medicine additive consists of: 2-5 parts of saffron, 8-20 parts of glossy privet fruits, 5-20 parts of leonurus heterophyllus, 5-15 parts of officinal magnolia bark, 7-18 parts of Chinese magnoliavine fruit and 6-10 parts of liquorice. The compound feed belongs to the technical field of fish feeds.

Description

technical field [0001] The invention relates to a compound feed for the reproduction ability of dace broodstock, in particular to a compound feed capable of enhancing the reproduction ability of dace broodstock, and belongs to the technical field of fish feed. Background technique [0002] Dace belongs to Cyprinidae, Cyprinidae, Dace subfamily, Dace genus, commonly known as earth carp, snow carp, flower carp. Dace body is long, both sides are flattened, the back is slightly raised in front of the dorsal fin, the abdomen is round and slightly straight, the head is short, and the snout is round and blunt. Mouth small, inferior, arc-shaped, upper and lower jaws with horny sharp edges, two pairs of barbels, and snout barbels thicker. Dace is an important freshwater economic fish in South China, with high quality and low price, and constant market demand. Its tender meat, delicious taste, large yield, high per unit area yield, wide source of feed, can adapt to a relatively fert...

Problems solved by technology

[0003] Although the reproductive technology of dace in my country is relatively mature, it mainly relies on the use of hormones or hormone analogs to induce labor. These hormones and hormone analogs such as gonadotropin-releasing hormone, dopamine antagonists, and dopamine depleting agents are chemical drugs. The long-term use of these chemicals not only leads to the decline of broodstock reproductive ability, seed degradation, environmental pollution and other problems, but also their residue and enrichment in seed will also affect human health.

When broodstock induce labor, the injection dose of these hormones and hormone analogues is too large or insufficient, which will easily lead to increased mortality of broodstock, lower fertilization rate and induced labor rate

In terms of use time, too early or too late will lead to failure of induced labor

In addition, inadvertent operation in the process of induced spawning will lead to broodstock damage and broodstock shock stress, resulting in non-production or dystocia, and even death of broodstock, which will bring serious economic losses to farmers.

[0004] Therefore, in order to overcome the artificial oxytocin technology with troublesome operation, high stress and high risk of injury in the artificial oxytocin process of the current dace broodstock breeding and to overcome the seed degradation, environmental pollution, environmental pollution, etc. Residues and low reproductive capacity of dace broodstock under natural conditions, etc., and the development of a nutrient-rich, green and environmentally friendly feed that can enhance the reproductive capacity of dace broodstock will be helpful for improving the reproductive capacity of dace broodstock, the development of artificial induced spawning technology and aquaculture. The sustainable development of the industry has important theoretical and practical significance
