Description

Technical Field

[0001] The invention relates to the technical field of aquaculture application, in particular to an artificial compound feed for breeding wide-bodied golden leech and a preparation method thereof. Background Art

[0002] Golden leech, also known as leech, is a kind of leech and the main origin of leech, a traditional animal medicinal material in my country. Golden leech has high medicinal value. In recent years, wild leeches have been affected by industrial pollution and large-scale capture, and their numbers have decreased sharply, and natural resources have gradually been exhausted. In order to solve the problem of leech resource shortage, artificial breeding has become an effective way. The breeding industry has flourished in many places and has become an emerging industry for local farmers.

[0003] However, with the development of the artificial breeding industry of wide-bodied golden leeches, the artificial breeding industry of wide-bodied golden leeches is increasingly affected by the feeding bait. In the artificial breeding process of wide-bodied golden leeches, the main feeding bait is fresh bait represented by snails. The cost of this fresh snail bait is relatively high, and there is a risk of food shortage due to seasonal changes or environmental factors. At the same time, this fresh snail bait is easy to carry viruses and bacteria, which will affect the health level and breeding success rate of wide-bodied golden leeches. As for the existing artificial compound feed, it is difficult for wide-bodied golden leeches to accept it due to problems such as feeding habits and palatability. Summary of the invention

[0004] The purpose of the present invention is to solve the problems that the cost of fresh snail bait is high and the risk of food shortage due to seasonal changes or environmental factors is easy to occur. At the same time, the fresh snail bait is easy to carry viruses and bacteria, which will affect the health level and breeding success rate of wide-bodied golden line leeches, and the existing artificial compound feed is not accepted by wide-bodied golden line leeches. Then an artificial compound feed for breeding wide-bodied golden line leeches and a preparation method thereof are proposed. The artificial compound feed simulates the appearance of live snails and provides the wide-bodied golden line leeches with the necessary conditions for adsorption and entanglement, thereby promoting their intake of the artificial compound feed in the snail. The compound feed is filled in the empty snail shell The compound feed is a paste. Compared with live snails, the cost of the compound feed is lower than that of live snails, and it can also replace live snails. In the preparation process of the artificial compound feed, the whole snail meat is freeze-dried into powder in advance, and the snail meat powder is used as an attractant and one of the main raw materials for the compound feed. Other nutrients are added to the feed to make it into feed, and then the texture, shape and nutritional components of the feed are optimized. The nutritional component is higher than that of live snails, and the sanitary conditions can be controlled during the preparation process to ensure that there are no viruses and bacteria in the feed, which helps to improve the health level and breeding success rate of the wide-bodied golden leech.

[0005] The object of the present invention can be achieved by the following technical scheme: an artificial compound feed for breeding wide-bodied golden line leech, comprising a compound feed and a snail shell, wherein the compound feed is filled in an empty snail shell; The compound feed contains whole snail meat meal, fish meal, chlorella powder, yeast powder, betaine and xanthan gum, and the weight ratio of whole snail meat meal, fish meal, chlorella powder, yeast powder, betaine and xanthan gum is 50-65%: 5-15%: 5-15%: 15-25%: 0.5-1.5%: 0.8-1.2%.

[0006] A further technical improvement of the present invention is that the weight ratio of whole snail meat powder, fish meal, chlorella powder, yeast powder, betaine and xanthan gum is 58%: 10%: 10%: 20%: 1%: 1%.

[0007] A further technical improvement of the present invention is that the shell is a square ring-edge shell.

[0008] A further technical improvement of the present invention is that the whole snail meat powder is the whole snail meat powder of the square ring-ribbed snail.

[0009] A further technical improvement of the present invention is that the compound feed is a paste.

[0010] A further technical improvement of the present invention is that the preparation method comprises the preparation of compound feed and the filling of the compound feed into the snail shell.

[0011] A further technical improvement of the present invention is that the preparation of the compound feed specifically comprises the following steps: Step 1: Select commercially available fish meal, chlorella powder, yeast powder, betaine and xanthan gum, grind them separately and pass them through an 80-mesh sieve; Step 2: Select live snails, take out the whole snail meat from the live snails, freeze-dry, crush, and pass through an 80-mesh sieve to obtain whole snail meat powder; Step 3: Evenly mix the fish meal, chlorella powder, yeast powder and betaine crushed and sieved in step 1 and the whole snail meat powder prepared in step 2 according to a weight ratio to obtain a raw material mixed powder; Step 4: put the crushed and sieved xanthan gum in step 1 into water and heat to dissolve, stirring continuously during heating until it is evenly distributed, to obtain warm xanthan gum hydrate; Step 5: Determine the weight ratio of the raw material mixed powder and xanthan gum according to the weight ratio of fish meal, chlorella powder, yeast powder, betaine and xanthan gum, and add the raw material mixed powder in step 3 to the warm xanthan gum hydrate in step 4 according to the weight ratio of the raw material mixed powder and xanthan gum, stir evenly, and obtain a paste-like compound feed.

[0012] A further technical improvement of the present invention is that in step 4, the ratio of xanthan gum to water is controlled at 1:50.

[0013] A further technical improvement of the present invention is that before the compound feed is filled into the snail shell, the snail shell is first cleaned and dried.

[0014] The further technical improvement of the present invention is that the compound feed of the paste prepared in step 5 is put into the snail shell, cooled at room temperature, and the artificial compound feed is prepared.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) In the present invention, the artificial compound feed for breeding of golden leeches is prepared by filling the compound feed into an empty snail shell, with the snail shell serving as a carrier of the compound feed to simulate the contents of a real live snail. This can promote the feeding of the artificial compound feed without changing the feeding habits of the golden leeches, thereby ultimately solving the problem that the artificial compound feed is not accepted by the golden leeches, thereby achieving the replacement of fresh live snail bait with artificial compound feed. By using artificial compound feed, the dependence on natural feed can be reduced, and the risk of food shortage caused by seasonal changes or environmental factors can be reduced. In addition, the preparation and feeding process of artificial feed is more controllable, which is convenient for large-scale breeding management, thereby improving breeding efficiency and economic benefits. (2) In the present invention, the artificial compound feed for breeding of wide-bodied golden leech combines multiple ingredients such as whole snail meat meal, fish meal, chlorella powder, yeast powder, betaine and xanthan gum through precise proportions, thereby providing comprehensive and balanced nutrition for wide-bodied golden leech. Whole snail meat meal provides high-quality animal protein, fish meal is rich in essential amino acids, chlorella powder contains multiple vitamins and minerals, yeast powder provides B vitamins, betaine helps to improve the palatability and nutritional value of the feed, and xanthan gum acts as a thickener to improve the physical properties of the feed. This comprehensive nutritional program helps the healthy growth of wide-bodied golden leech and improves its survival rate. (3) In the present invention, the artificial compound feed for breeding wide-bodied golden leech is a compound feed filled in an empty snail shell, and the compound feed is a paste. Since the compound feed is filled in an empty snail shell and the compound feed is a paste, this design can effectively reduce the solubility of the artificial compound feed in water, thereby reducing feed waste. Compared with live snails, the artificial compound feed has a lower cost and can replace live snails. This cost-effectiveness advantage makes large-scale breeding of wide-bodied golden leech more economical and feasible. In addition, the artificial compound feed can control sanitary conditions during the preparation process to ensure that there are no pathogens in the feed, which helps to improve the health level and breeding success rate of wide-bodied golden leech; (4) In the present invention, in the method for preparing the artificial compound feed for breeding of wide-bodied golden leech, by freeze-drying the whole snail meat to make powder and adding it to the compound feed, the palatability of the compound feed can be effectively improved and the nutritional content of the compound feed can be guaranteed. At the same time, the muscle part of the front of the snail meat can be fully utilized, which solves the problem that when eating live snails, the wide-bodied golden leech can only eat the visceral tissue at the back of the snail meat, resulting in waste of the front muscle tissue. In addition, the utilization rate of the snail meat can be effectively improved, the input cost of the snail meat can be reduced, and the economic benefits of breeding of wide-bodied golden leech can be improved; (5) In the present invention, the method for preparing the artificial compound feed for breeding of wide-bodied golden leech has clear steps, simple operation, easy to master, suitable for large-scale production, and can ensure the quality and consistency of the feed to meet the needs of large-scale breeding. At the same time, the preparation method can flexibly adjust the feed formula according to different breeding environments and seasonal changes to adapt to the growth needs of wide-bodied golden leech and enhance its adaptability to environmental changes. This flexibility and adjustability are of great significance for improving the success rate of breeding and reducing costs. DETAILED DESCRIPTION
