Background
Many easily oxidizable components are present in feed, such as vitamins, various fats, plant processing by-products, animal derived feed, etc. Meanwhile, the palatability and the use effect of the feed can be influenced by oxidation in the processes of production, transportation and storage of the feed. Feed antioxidants are a class of substances that are effective in preventing or retarding the autoxidation of lipid compounds: can be used for feed containing high fat to prevent fat oxidation, rancidity and deterioration; it is also commonly used in vitamin-containing premixes to prevent oxidative failure of the vitamin; it can be used in feed material with high content of carotene and carotenoid to prevent oxidation damage of provitamin A and pigment, and increase coloring effect and utilization rate of skin, cuticle, egg yolk, shrimp and crab. Antioxidants are therefore widely used in feed.
The antioxidants currently available in the feed additives list are mainly: dibutyl hydroxy toluene (BHT), Butyl Hydroxy Anisole (BHA), Ethoxy Quinoline (EQ), tert-butyl hydroquinone (TBHQ) and Propyl Gallate (PG), etc., but single antioxidants such as TBHQ, PG, etc. are expensive and difficult to be directly dissolved in Ethoxy Quinoline (EQ), and simultaneously, considering that different antioxidants have advantages on different substrates, the effect of the compound antioxidant is far better than that of a single antioxidant raw material, and the cost performance is higher.
The compound antioxidant product in the current market is mainly prepared by taking solid powder as a main material and adsorbing the solid powder through an ore carrier, iron ions in the ore are contacted with most of phenolic antioxidants to be oxidized to generate red quinone substances, and the content and the sense of the antioxidants are influenced during the storage period of the product, so that the protective effect of the antioxidants on feed is influenced.

(2) adding tert-butyl hydroquinone, ethoxyquinoline and soybean oil into the solution obtained in the step (1);
(3) and (3) stirring the solution obtained in the step (2) until the solution is uniformly mixed to obtain the liquid feed antioxidant.
Further, the mass ratio of the benzyl alcohol to the propyl gallate in the step (1) is more than or equal to 3.
Further, the stirring temperature in the step (3) is 50-70 ℃.
Further, the stirring time in the step (3) is 0.25-1 h; preferably, the stirring time in the step (3) is 0.5 h.
The invention has the beneficial effects that:
aiming at the situation that less liquid compound antioxidant is a breakthrough point, the Propyl Gallate (PG) which is difficult to dissolve is dissolved in benzyl alcohol in advance, the tert-butyl hydroquinone (TBHQ) which can be dissolved by heating is added, and then the Ethoxyquinoline (EQ) and the carrier soybean oil are added and stirred to be dissolved uniformly. The feed enterprise passes through liquid grease and adds the device, on the direct spraying of the antioxidant of liquid to the fodder, disposable addition grease and antioxidant on the one hand can pass through the abundant grease that diffuses of liquid grease with the antioxidant to the fodder on the other hand adds through scientific compatibility, and the different single antioxidant of full play is to the advantage of different fodder substrates, more has the price/performance ratio, and the contact with the air also can be reduced to the liquid antioxidant product in addition, reduces the loss of self content.
