Description

Technical Field

[0001] This invention belongs to the field of feed additive technology in animal husbandry, and particularly relates to a method for preparing a fattening nutrient for duck farms. Background Technology

[0002] In the fattening process of ducks, a reasonable nutrient ratio and efficient feed additives are crucial for improving the growth rate and meat quality of ducks. While existing feed formulations can meet the basic nutritional needs of ducks to a certain extent, there is still room for improvement in terms of feed conversion rate, promoting rapid weight gain, and improving meat quality. Currently, the low feed conversion rate leads to increased feed costs, and some feeds result in slow weight gain and long fattening periods; furthermore, inconsistent meat quality affects market competitiveness. Therefore, this invention aims to provide a novel fattening nutrient agent for duck farms to optimize feed formulation and improve the fattening effect of ducks. Summary of the Invention

[0005] (2) Add fish bone powder, traditional Chinese medicine additives, enzyme preparations and microecological preparations to step (1), continue to stir evenly, grind and sieve to obtain raw material powder;

[0006] (3) The mixed raw material powder is granulated into pellet feed by passing it through a pellet mill.

[0007] As an improvement, the mass ratio of corn flour, wheat bran, rice bran and soybean meal in step (1) is 1-10:40-50:30-40:1-5.

[0008] As an improvement, the fish bone powder mentioned in step (2) is prepared by mixing blackfish meat and fish bones in a weight ratio of 1:10 to 20, with an average particle diameter of 0.1-2 mm, accounting for 1 to 1.5 wt% of the total nutrient solution.

[0009] As an improvement, the herbal additives mentioned in step (2) are added by processing into dry powder, accounting for 1 to 1.5 wt% of the total nutrient, including 1-10 parts of Eucommia ulmoides, 30-40 parts of Artemisia argyi, 1-15 parts of Atractylodes lancea, and 20-40 parts of Portulaca oleracea.

[0010] As an improvement, the enzyme preparation in step (2) accounts for 0.1 to 1.0 wt% of the total nutrient and includes at least one of triacylglycerol hydrolase, glycerol, and mono- or diglyceride.

[0011] As an improvement, the microecological preparation mentioned in step (2) accounts for 1.5 to 2.5 wt% of the total nutrient preparation and includes at least two of the following: Bifidobacterium live bacteria preparation, Lactobacillus acidophilus preparation, lactulose, sucrose oligosaccharide, cottonseed oligosaccharide, isomaltooligosaccharide, corn oligosaccharide and soybean oligosaccharide.

Detailed Implementation

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below, so that those skilled in the art can better understand the advantages and features of the present invention, thereby making a clearer definition of the scope of protection of the present invention. The embodiments described in this invention are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] This invention proposes a nutrient formula for fattening ducks, comprising corn flour, wheat bran, rice bran, soybean meal, fish meal, traditional Chinese medicine additives, enzyme preparations, and microecological preparations. Wheat bran and rice bran are the main components, reducing costs while providing sufficient plant fiber to ensure the ducks feel full. Preferably, the mass ratio of wheat bran to rice bran is set at 40-50:30-40.

[0015] In this invention, compared with conventional technology, fish bone powder is added. The fish bone powder is prepared by mixing black carp meat and fish bones in a weight ratio of 1:10 to 20. The average particle diameter is 0.1-2 mm, and it accounts for 1 to 1.5 wt% of the total nutrient solution. This design can increase the nutrients required for duck reproduction, and black carp is the most suitable.

[0016] In addition, herbal additives are added. In order to facilitate absorption, they are added in the form of dry powder in this invention, accounting for 1 to 1.5 wt% of the total nutrient solution, including 1 to 10 parts of Eucommia ulmoides, 30 to 40 parts of Artemisia argyi, 1 to 15 parts of Atractylodes lancea, and Portulaca oleracea.

[0017] Eucommia ulmoides 1-10 parts, the extract of Eucommia ulmoides chlorogenic acid has antibacterial effect, can clear heat and detoxify, and improve the stress resistance of livestock and poultry; Eucommia ulmoides flavonoids can stimulate follicle development, promote ovulation, improve production performance, reduce production costs, enhance immunity, promote growth, improve the quality of poultry carcasses, and can reduce abdominal fat rate in the body and increase eviscerated rate of broilers.

[0018] Atractylodes lancea (1-15 parts) has a good preventive effect against infectious bronchitis, infectious laryngitis, duck plague, infectious coryza, and eye diseases in ducks. Purslane (20-40 parts) contains nicotinic acid saponins, tannic acid, oxalic acid, urea, vitamin A, vitamin B, vitamin C, potassium nitrate, potassium sulfate, potassium chloride, etc., and has the effects of clearing heat and detoxifying, stopping bleeding and dysentery.

[0019] Artemisia argyi (30-40 parts) contains protein, fat, vitamin B, vitamin E, various essential amino acids, minerals, chlorophyll, etc. It can prevent and reduce the occurrence of lymphatic diseases in duck farming. At the same time, it can improve feed conversion rate, promote rapid weight gain in ducks, and improve meat quality to a certain extent.

[0020] In this invention, the enzyme preparation accounts for 0.1 to 1.0 wt% of the total nutrient solution and includes at least one of triacylglycerol hydrolase, glycerol, and mono- or diglyceride.

[0021] Preferably, the microecological preparation accounts for 1.5 to 2.5 wt% of the total nutrient solution and includes at least two of the following: Bifidobacterium live bacteria preparation, Lactobacillus acidophilus preparation, lactulose, sucrose oligosaccharide, cottonseed oligosaccharide, isomaltooligosaccharide, corn oligosaccharide, and soybean oligosaccharide.

Specifically, it includes 10 wt% corn flour, 40 wt% wheat bran, 40 wt% rice bran, 5 wt% soybean meal, 1.5 wt% fish bone meal, 1.3 wt% traditional Chinese medicine additives, 0.7 wt% enzyme preparations, and 1.5 wt% microecological preparations.

[0027] Example 3

[0028] A nutrient formula for duck fattening includes corn flour, wheat bran, rice bran, soybean meal, fish meal, traditional Chinese medicine additives, enzyme preparations, and microecological preparations.

[0029] Example 4: A batch of duck fattening nutrients was prepared according to the above formulation and preparation method. Under the same feeding conditions, ducks using this enzyme preparation showed a 20% increase in weight gain and a 15% increase in feed conversion rate compared to ducks using conventional feed.

[0030] Example 5: In another set of experiments, the nutrient formula was further optimized by adjusting the types and proportions of traditional Chinese medicine additives. The results showed that ducks using the optimized formula not only experienced further improvements in weight gain and feed conversion rate, but also significantly improved meat quality.
