AI Technical Summary

Problems solved by technology

At present, some older animals can be fed without antibiotics, but young animals cannot be fed without antibiotics due to immature digestive system, breeding scale, environment, and management technology.
Especially if antibiotics are not added to the compound feed of laying chickens, the feed utilization rate will be reduced, coccidiosis and enteritis will occur frequently, and the body weight and shank length will not meet the standard, which will seriously affect the production performance in the later laying period

Embodiment 1

[0038]A feed additive, 100g of which is composed of the following components: 10g allicin, 5g oregano oil, 10g Flammulina velutipes polysaccharide, 15g Boluohui alkaloid, 5g Artemisia annua, 10g Changshan, 5g Agrimony, 10g Bupleurum, 10g chitosan oligosaccharide, 20g taurine.

[0039] Feed additives are made by the following steps:

[0040] 1) Pulverize 5g Artemisia annua, 10g Changshan, 5g Agrimony, and 10g Bupleurum with an ultrafine pulverizer, and pass the powder through an 80-mesh analytical sieve;

[0041] 2) Mix the mixture prepared in step 1) with 10 g of allicin, 5 g of oregano oil, 10 g of Flammulina velutipes polysaccharide, 15 g of Boluohui alkaloid, 10 g of chitosan oligosaccharide, and 20 g of taurine to prepare a feed additive.

Embodiment 2

[0043] A kind of compound feed for laying chickens, 100g of this compound feed for laying chickens comprises the following components by weight:

[0044] Pregelatinized brown rice 15g, puffed corn 30g, potato flour 10g, flour 10g, puffed soybean 10g, fermented soybean meal 9.5g, super steam fish meal 3g, rice protein powder 5g, emulsified coconut oil powder 2g, calcium carbonate 1.5g, diphosphate Hydrogen calcium 1.2g, sodium chloride 0.3g, trace element premix 0.2g, vitamin premix 0.5g, lysine 0.1g, methionine 0.15g, compound acidifier 0.5g, compound enzyme preparation 0.05g, feed additive 1g;

[0045] Wherein, feed additive is made according to the composition, content and method of embodiment 1;

[0046] Among them, the trace element premix is ​​made of zinc sulfate, manganese sulfate, basic copper chloride, ferrous sulfate, yeast selenium, calcium iodate, cobalt chloride, etc., mixed with carrier zeolite powder and rice husk powder;

[0047] Vitamin premixes are vitamin ...

[0066] Application of Compound Feed for Laying Chicks

[0067] 1 Test method

[0068] 1.1 Experimental design and grouping

[0069] A total of 1200 1-day-old commercial Hai-Line brown layer hens were selected and randomly divided into 3 groups, with 4 replicates in each group and 100 chickens in each replicate. Control group feeds commercially available common laying hen brooding stage feed product (containing 25mg / kg colistin sulfate), and test group feeds the feed of embodiment 2 respectively, does not contain feed additive and adds the remaining components of 25mg / kg colistin sulfate The antibiotic group identical with embodiment 2 components.

[0070] 1.2 Test time

[0071] The test period is 14 days.

[0072] 1.3 Feeding management

[0073] This experiment was carried out in a chicken farm in Cangzhou, Hebei. The test chickens were raised in 3-layer cages, free to eat and drink, and the light, temperature and humidity were strictly in accordance with the requirements...

Abstract

The invention discloses a feed additive, an antibiotic-free laying chick mixed feed, and a preparation method of the mixed feed. The feed comprises pre-gelatinized brown rice, puffed corn, whole potato flour, wheat flour, puffed soybeans, fermented soybean meal, super steamed fishmeal, rice protein powder, emulsified coconut oil powder, calcium carbonate, calcium dihydrogen phosphate, sodium chloride, a trace element premix, a vitamin premix, lysine, methionine, a composite acidifier, a composite enzyme preparation and the feed additive; and raw materials of the feed additive comprise garlicin, origanum oil, Flammulina velutipes polysaccharides, Macleaya cordata alkaloids, Artemisia carvifolia, antifeverile dichroa root, Agrimonia eupatoria, radix bupleuri, chitosan oligosaccharides and taurine. The feed does not contain antibiotics, the anti-nutritional factors of the raw materials of the feed are low, and most raw materials are preprocessed, so the safety and the palatability of the raw materials are improved, the feed intake of chicks is improved, and the feed has high utilization rate and high uniformity.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a compound feed for laying chickens without adding antibiotics and a preparation method thereof. Background technique [0002] Studies have shown that childhood obesity is related to residual antibiotics in the body. The use of used antibiotics is essentially short-term high-dose exposure, while antibiotic exposure from food or the environment is long-term low-dose exposure. Antibiotics enter the intestinal tract, which may change the balance of microbial flora and affect Substance metabolism is likely to cause obesity. At the same time, long-term abuse of antibiotics will accelerate the emergence of bacterial resistance, and super bacteria will appear, making no medicine available; long-term and large-scale use of antibiotics will cause the immunity and resistance of animals to decline, and frequent diseases; meat products, eggs and milk and other residual antibiotics can c...
