A kind of compound iron dextran injection and preparation method thereof

Abstract

The invention discloses a compound iron-dextrin injection and a preparation method thereof. The injection is prepared from iron-dextrin, butafosfan and injection water. The preparation method comprises the following steps: (1) putting the prescribed butafosfan in a container, and adding a proper amount of injection water until the butafosfan is completely dissolved, regulating the pH to be 5.5-6.0 with a NaOH solution to obtain a butafosfan solution for later use; (2) adding a prescribed iron-dextrin solution into the butafosfan solution, uniformly mixing, and fixing the volume to the prescription with the injection water, sufficiently and uniformly mixing to obtain a mixed liquid; and (3) filtering and subpackaging the mixed liquid, filling, and sterilizing to obtain the compound iron-dextrin injection. The compound iron-dextrin injection can be used for preventing and treating secondary infection and other diseases caused by piglet anemia and low immunity, and promoting metabolism and stress resistance of piglets, so that the immunity of piglets can be strengthened, the energy utilization can be improved, and the slaughter weight of piglets can be increased.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine, and relates to a compound injection for preventing and treating comprehensive disorders caused by anemia of young animals, lack of trace elements, low resistance of animal bodies and the like. Background technique [0002] At present, there are outbreaks of major diseases in pig farms across the country. Almost all pig farms have been attacked by diseases such as PRRS, mycotoxins, circovirus, pseudorabies virus, and Haemophilus parasuis for a long time. Or the trend of sporadic infection, the probability of causing newborn young animals to be sick is also increasing day by day. In addition, due to reasons such as feeding management errors and untimely prevention, iron deficiency anemia and trace element deficiency in young animals, low animal body resistance and other reasons cause the body Functional disorders and other comprehensive disorders. [0003] Taking piglets as an example,...

Problems solved by technology

[0003] Taking piglets as an example, the total iron reserves of piglets at birth are 40-50 mg. For every 1 kg weight gain of suckling piglets, the iron requirement is about 35 mg, and the iron requirement is 7-8 mg / d. 200mg, while the iron content of breast milk is only 0.2mg / 100g, the daily iron intake of piglets from breast milk is less than 1 / 7 of the total requirement, which is far from meeting the needs of normal development of piglets. Days of age, the amount of iron stored in the body will be exhausted. If it cannot be replenished in time, iron deficiency anemia will easily occur, which will lead to the destruction of the redox process of the body, weaken the digestion and absorption function of the piglet, and reduce the body's resistance to cause secondary infection.

In addition, stress factors such as weaning and turning circles cause the growth performance of piglets to decline, and the weight of the weaned litter is small, which seriously affects the economic benefits of pig raising and has caused heavy losses to the pig raising industry.
