Description

Technical Field

[0001] This invention relates to the field of feed, and in particular to a feed for accelerating the growth and development of Ding'an geese and its preparation method. Background Technology

[0002] Ding'an geese, a superior local breed in Hainan Province, possess excellent meat quality and strong environmental adaptability. However, this breed suffers from slow growth rate and low feed conversion rate, resulting in a long rearing period for individuals to reach market weight, which hinders the improvement of the economic benefits of Ding'an goose farming. Gut health is a key factor affecting the growth and development rate of geese, directly regulating the body's digestion, absorption, and utilization of nutrients. In actual farming, Ding'an geese are susceptible to various factors such as feed stress and environmental changes, leading to problems such as gut microbiota imbalance, insufficient digestive enzyme secretion, and reduced feed nutrient utilization, thus preventing the full realization of their growth potential.

[0003] To promote the growth and development of Ding'an geese and shorten the feeding cycle, traditional farming methods typically involve adding antibiotics or chemically synthesized growth promoters to their feed. While these additives can maintain intestinal health and increase growth rate to some extent, long-term continuous use can easily induce intestinal flora imbalance, the development of antibiotic resistance in pathogens, and drug residues in goose meat tissue. This not only adversely affects the health of the geese themselves but also poses potential risks to food safety and the ecological environment. Currently, with the comprehensive implementation of policies to reduce and limit antibiotic use in the livestock industry, developing green, safe, and efficient feed additive solutions to replace antibiotics, improve intestinal physiological function, and promote growth performance has become an urgent need in this field.

[0004] Therefore, developing a specialized feed that can effectively accelerate its growth and development and shorten its growth cycle remains a pressing technical problem to be solved. Summary of the Invention

[0005] In view of this, the present invention proposes a feed for Ding'an geese and a method for preparing the same.

[0006] The technical solution of this invention is implemented as follows: a feed for accelerating the growth and development of Ding'an geese, the feed comprising the following raw materials in parts by weight: 58-66 parts corn, 15-25 parts soybean meal, 5-12 parts rice bran, 3-6 parts grass meal, 0.8-1.6 parts dicalcium phosphate, 0.02-0.1 parts L-lysine, 1.5-2.5 parts compound traditional Chinese medicine, 0.1-0.4 parts compound microbial strains, and 1-2 parts compound premix containing vitamins and trace elements; the compound traditional Chinese medicine is composed of the following medicinal materials: Amomum villosum, Alpinia oxyphylla, Portulaca oleracea, and Morinda officinalis; the compound microbial strains are composed of the following microbial strains: Bacillus pumilus, Candida utilis, Lactobacillus plantarum, and Clostridium butyricum.

[0007] Furthermore, the compound Chinese medicine is composed of the following medicinal materials in parts by weight: 3.5-4.5 parts of Amomum villosum, 2.5-3.5 parts of Alpinia oxyphylla, 0.8-1.2 parts of Portulaca oleracea, and 1.5-2.5 parts of Morinda officinalis.

[0008] Furthermore, the compound Chinese medicine is composed of the following medicinal materials in parts by weight: 4 parts Amomum villosum, 3 parts Alpinia oxyphylla, 1 part Portulaca oleracea, and 2 parts Morinda officinalis.

[0009] Furthermore, the compound microbial strain consists of Bacillus pumilus, Lactobacillus plantarum, Candida utilis, and Clostridium butyricum.

[0010] Furthermore, the compound microbial strain consists of the following microbial strains in parts by weight: 40-50 parts of Bacillus pumilus, 25-35 parts of Candida utilis, 10-15 parts of Lactobacillus plantarum, and 10-15 parts of Clostridium butyricum.

[0011] Furthermore, the composite premix comprises the following raw materials in parts by weight: 3-4 parts of compound vitamins, 9-12 parts of trace elements, and 85-90 parts of carrier.

[0012] Furthermore, the compound vitamins include vitamin A, vitamin D, vitamin E, vitamin K, and vitamin B3; the trace elements include ferrous sulfate, zinc sulfate, calcium iodate, sodium selenite, and copper sulfate; and the carrier includes rice husk powder and zeolite powder in a mass ratio of 0.9-1.1:0.9-1.1.

[0013] This invention provides a method for preparing feed to accelerate the growth and development of Ding'an geese, comprising the following steps: (1) Dry, pulverize and sieve the prescribed amounts of Amomum villosum, Alpinia oxyphylla, Portulaca oleracea and Morinda officinalis respectively to obtain compound Chinese medicine powder; (2) Mix the bacterial powders of Bacillus pumilus, Lactobacillus plantarum, Candida utilis and Clostridium butyricum in the prescribed amounts to obtain a compound bacterial powder; (3) After crushing the corn, soybean meal, rice bran and grass powder in the formula, mix them evenly with dicalcium phosphate, L-lysine and compound premix containing vitamins and trace elements to obtain the basic mixture. (4) Add the compound Chinese medicine powder from step (1) and the compound microbial powder from step (2) to the basic mixture and mix evenly to obtain powdered feed.

[0014] Furthermore, after step (4), a pelleting step is also included: the mixed material is conditioned and pelleted at a temperature of 40-45℃ to produce pellet feed.

[0015] Furthermore, in step (1), the drying temperature is 40-50℃, and the powder is pulverized and passed through a 60-80 mesh sieve; in step (3), the corn, soybean meal, rice bran, and grass powder are pulverized and passed through a 20-40 mesh sieve.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The feed of the present invention is based on a compound premix containing corn, soybean meal, rice bran, grass meal, dicalcium phosphate, L-lysine, vitamins and trace elements, and is compounded with specific Chinese herbal medicine components (Amomum villosum, Alpinia oxyphylla, Portulaca oleracea, Morinda officinalis) and compound bacterial strains (Bacillus pumilus, Lactobacillus plantarum, Candida utilis, Clostridium butyricum). This combination can accelerate the growth and development of Ding'an geese, effectively reduce the feed conversion ratio, and increase the slaughter rate.

[0017] This invention has the following advantages in Ding'an goose farming: (1) Reduce feed conversion ratio and improve slaughter performance. The feed conversion ratio of Ding'an geese fed with this feed was significantly reduced and the feed conversion efficiency was improved. Experiments have shown that adding the specific compound Chinese medicine and compound microbial strains to the diet can effectively improve slaughter performance and increase slaughter rate.

[0018] (2) The synergistic combination of the Chinese herbal components provides multi-target regulation and is green and safe. Amomum villosum promotes qi circulation and eliminates dampness, warms the spleen and stimulates appetite, while Alpinia oxyphylla warms the spleen, reduces salivation, stops diarrhea and strengthens the intestines. The combination of the two herbs eliminates dampness and strengthens the spleen. Purslane clears heat and detoxifies, cools the blood and stops dysentery, and can neutralize the warm and dry nature of Amomum villosum and Alpinia oxyphylla to prevent the accumulation of damp heat. Morinda officinalis tonifies kidney yang, strengthens tendons and bones, and fortifies the bones. The combination of the four herbs constructs a multi-target regulatory pathway of "strengthening the spleen and stimulating appetite, clearing heat and eliminating dampness, and tonifying the kidney and strengthening bones", with significant synergistic effects. The Chinese herbal components are of natural plant origin, with no drug residues, no risk of drug resistance, and are green and safe.

[0019] (3) Precise formulation of compound microbial strains to achieve synergistic effects throughout the entire gut. Bacillus pumilus efficiently secretes cellulase and xylanase to specifically degrade forage fiber and release nutrients; Candida utilis provides cell protein and digestive enzymes to improve feed palatability; Lactobacillus plantarum rapidly produces acid to inhibit bacteria in the small intestine and produces bacteriocins to inhibit pathogens; Clostridium butyricum produces large amounts of butyric acid in the cecum, directly providing energy to the intestinal epithelium, promoting intestinal villi development, and increasing the absorption area. This combination of microbial strains follows an "aerobic-facultative-anaerobic" ecological niche relay colonization model, specifically enhancing the digestibility of crude fiber in Ding'an geese and significantly improving growth performance and feed utilization efficiency.

[0020] (4) Mutual synergy between bacteria and medicine produces a synergistic effect of 1+1>2. Polysaccharides, flavonoids and other components in traditional Chinese medicine can be used as prebiotics by the compound bacteria, accelerating the activation and proliferation of probiotics in the intestine; the various enzyme systems produced by the compound bacteria can destroy plant cell walls, promote the dissolution and absorption of active ingredients in traditional Chinese medicine, and the acidic environment can further promote the conversion of certain glycosides into more active aglycones. The synergistic effect between bacteria and medicine makes the efficacy of traditional Chinese medicine and the colonization capacity of bacteria exceed the level when used alone, further strengthening the comprehensive breeding effect of promoting growth, resisting stress and improving immune performance.

The average weight of each group was measured before the experiment. The experiment lasted for 50 consecutive days. Daily feed intake was recorded and average daily weight gain was calculated. The feed conversion ratio was calculated based on the average daily feed intake and average daily weight gain. Finally, the dressing percentage was measured according to the "Terminology and Measurement Statistical Methods for Poultry Production Performance".

[0042] Average feed conversion ratio = (average daily feed intake ÷ average daily weight gain); Average daily feed intake (ADFI): The average daily feed intake during the trial period, i.e., total feed intake ÷ number of trial days; Average daily weight gain (ADG): The average weight gain per day during the trial period, i.e. (final weight - initial weight) ÷ number of trial days; Slaughter rate = (slaughter weight ÷ pre-slaughter live weight) × 100%.

[0045] The experimental results show that the feeds in Examples 1-9 all exhibited low feed conversion ratios and excellent slaughter performance with high dressing percentages. Compared to Example 1, the feeds in Comparative Examples 1-4 had significantly higher feed conversion ratios and significantly lower dressing percentages. These results indicate that adding the specific compound traditional Chinese medicine and compound microbial strains described in this invention to the feed can reduce the feed conversion ratio of Ding'an geese while improving their slaughter performance.
