Please select the most similar patent number from A, B, C and D. Which number is?
Disclosed is a feed composition, a preparation method therefor, and an application thereof in raising animals. The composition comprises a polyglycerol fatty acid ester having a pH value of 2.5-3.5. The fatty acid has 6-14 carbon atoms and is exemplified as laurel acid, caproic acid, caprylic acid, capric acid, or myristic acid. The number of polyglycerol molecules in the polyglycerol fatty acid ester is 1-5.
A: Disclosed are a precursor compound of a hexahydro-beta-acid component compound, a feed composition and use thereof. A precursor compound of a hexahydro-beta-acid component compound having a structure represented by formula (I) or a solvate thereof and a feed-acceptable salt thereof, wherein R 1  is selected from substituted or unsubstituted C 1 -C 2  alkyl, and R 2  or R 3  is independently selected from H and substituted or unsubstituted linear or branched C 2 -C 4  carbonyl. In the present invention, it is found that fatty acid esterified precursor compounds of the hexahydro-beta-acid component compound have good stability under high temperature conditions, and overcome the problem of degradation of active ingredients caused by high temperature granulation of the hexahydro-beta-acid component compound during feed processing. Further, in the present invention, it is also found that hexahydro-beta-acid component compound propionate or butyrate and a feed-acceptable salt or solvate thereof among the fatty acid esterified precursor compounds of the hexahydro-beta-acid component compound can withstand a high temperature process of feed processing, and also have an effect substantially equivalent to the effect of the hexahydro-beta-acid component compound in breeding use.
B: Disclosed are a pharmaceutical composition comprising a polymyxin synergist and the use thereof. The oxygen-containing hydrocarbon derivative containing 4 to 18 carbon atoms includes a fatty alcohol, a fatty acid and a fatty acid glyceride and serves as a polymyxin synergist, in particular as a synergist for a strain sensitive to the polymyxin inhibiting effect and as a drug-resistance reversal agent for polymyxin. Also disclosed is a pharmaceutical composition of the polymyxin synergist. The pharmaceutical composition is further used for preparing a drug and an animal feed additive for the treatment of a disease caused by polymyxin-sensitive bacterial infection or drug-resistant bacterial infection, and provides a more effective application space for the use of polymyxin, and is of great importance in application in the fields of pharmaceutics and animal breeding.
C: Disclosed are a non-dairy cream for baking and the preparation method thereof, same being made of the following raw materials in percentages by weight: 28-40% of plant fats, 0.02-0.5% of lecithin, 0.02-2% of salt, 0.02-0.5% of diacetyl tartaric acid mono-(bis-)glycerides, 0.05-0.1% of mono- and bis-glycerol fatty acid esters, 0-0.2% of sucrose fatty acid esters, 0-0.5% of polyglycerol esters, 2-5% of sweet whey powder, 0.05-1% of denatured cellulose, 0.1-2.5% of sodium caseinate, 0-0.5% of sodium stearyl lactylate, 0-0.5% of lactic acid glycerin fatty acid ester, 0-0.3% of sodium alginate, 0.002-0.2% of sodium erythorbate, 3-6% of sugar, 3-6% of glucose syrup and 10-18% of high fructose corn syrup, the balance being water.
D: A non-hydrogenated mixed butterfat and non-dairy cream, and a preparation method therefor. The cream is made from the following ingredients in percentage by weight: non-hydrogenated vegetable oil: 8％-18％; sorbitan monostearate: 0.05％-0.5％; citric and fatty acid esters of glycerol: 0.02％-0.5％; mono- and di-glycerides of fatty acids: 0.05％-1％; lactic acid esters of monoglyceride: 0.02％-1％; sodium stearoyl lactylate: 0.02％-0.5％; sucrose fatty acid ester: 0.05％-0.5％; polyglycerol ester: 0.02％-0.5％; carrageenan: 0.01％-0.1％; microcrystalline cellulose: 0.05％-0.8％; modified cellulose: 0.05％-1％; sodium caseinate: 0.1％-1.5％; potassium dihydrogen phosphate: 0.02％-0.2％; sugar: 2％-6％; glucose syrup: 2％-12％; butterfat containing dairy product: 8％-18％; and water: 20％-60％. The preparation method comprises: preparing an oil phase mixture and an aqueous phase mixture, adding the aqueous phase to the oil phase, stirring uniformly, pasteurizing, homogenizing, stirring, bottling, and freezing and preserving.
