Problems solved by technology

[0009] The purpose of the invention patent application CN200910193736.4 is to provide the source of protein raw materials, without explicitly mentioning its function in application; the invention patent application CN98809331 is to prepare protein peptide feed with algae dregs; Phaffia yeast is mixed and used for eel farming; US patent applications US20090864399 and US2011138682A1 are aimed at the cultivation, harvesting and processing of a Scenedesmus, and its application is only briefly mentioned in the background description without explicitly mentioning its function
The patent CN98809331.6 has the following deficiencies: 1. The patent focuses on the protection of the feeding system, and the key technologies such as feed formula, processing, and storage are not clear; 2. The range of raw materials containing Ω-3 HUFA is too large and vague, and the discussion Plants, animals, and microorganisms containing omega-3 HUFA are covered, but only the raw materials

Embodiment 1

[0057] Embodiment 1 Prototheca powder

[0058] Nannochloropsis oculata was purchased from the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences with a registration number of C1502. It was cultured in an autotrophic manner and obtained after concentration, desalination and drying.

[0059] Accurately weigh 9Kg of Nannochloropsis powder (1 laying hen*150g / day*2%), stir 11Kg of corn flour for 30 minutes until uniform, and make poultry feed additive 1, vacuum-pack it in an aluminum foil bag, and keep it at room temperature Preservation, specification 1Kg / bag.

[0060] 600 laying hens were raised in the same batch for about 150 days, divided into 6 cages on average, 100 in each cage, and pre-raised with commercially available common poultry feed for 7 days before the experiment. Three cages were randomly selected as the control group, and the remaining three cages were used as the experimental group. The experimental group was fed with 2 bags of alg...

Embodiment 2

[0071] Embodiment 2 broken wall powder+antioxidant

[0072] Chlorella sp was purchased from the Institute of Hydrobiology, Chinese Academy of Sciences, with a registration number of FACHB-1298. It was cultured in an autotrophic manner, and was broken through conventional concentration, desalination, drying, and ultrafine grinding. The breaking rate was ≥ 95%.

[0073] Get broken chlorella powder 9Kg (1 laying hen * 150g / day * 2%), BHT 2.7g (9Kg * 0.03%, a kind of antioxidant), after stirring in a small mixer for 10 minutes, then Add 11Kg of corn flour and continue to stir for 30 minutes until uniform, making poultry feed additive 2, vacuum-sealed in aluminum foil bags, and stored at room temperature, with a specification of 1Kg / bag.

[0074] Animal selection, grouping, feeding methods, and sampling are the same as in Example 1. Additive 2 accounts for 4.0% of the total mass of poultry daily feed, wherein chlorella powder accounts for 2% of the total mass of poultry daily fe...

Embodiment 3

[0085] Embodiment 3 algal meal+probiotics

[0086] Schizochytrium sp. was purchased from the General Microorganism Center of China Committee for Culture Collection of Microorganisms, and its number is CCTC No.M209059. The algae powder was produced by heterotrophic fermentation, and the oil was extracted from the algae powder to obtain the Schizochytrium meal. The micro-ecological preparation adopts the "intestinal power" product produced by Beijing Bangshifu Biotechnology Co., Ltd., and the main ingredients are 6 strains of beneficial bacteria (clostridium butyricum, lactobacillus, bacillus subtilis, bacillus licheniformis, natto bacteria, yeast bacteria) and three functional polysaccharides (xylooligosaccharides, fructooligosaccharides, chitosan).

[0087] Get 18Kg of Schizochytrium meal (1 laying hen*150g / day*4%), 3.6g of probiotics (18Kg*0.02%), stir in a small mixer for 10 minutes, then add 2Kg of sesame cake and continue to stir for 30 minutes. Minutes until uniform, mad...
