Later-stage fortified feed additive applied to domestic animals and preparation method thereof

Abstract

The invention provides a later-stage fortified feed additive applied to domestic animals and aims to achieve the purpose of improving body type under the safe and pollution-free precondition by combining later-stage physiological characteristics and growth potential of the existing farming varieties and preparing the feed additive in the stage from the angle of enhancement of protein deposition through methods of enhancing nutrition and improving immune stress. Through the later-stage fortified feed additive, the stress state of the domestic animals is reduced; the immunity of the domestic animals is improved; the nutrition supply is improved from the angle of enhancement of protein deposition by combining the later-stage characteristics of the domestic animals and taking the demand of proteins and amino acids into special consideration, so that the deposition of lean meat is improved; the body type of the domestic animals is improved; the vitamin nutrition is enhanced; the lean meat rate of the domestic animals is increased; meanwhile, the addition of the later-stage mineral elements is enhanced; the body electrolyte balance is improved; the proper pH value in the tissue is maintained; the loss of the water is reduced, so that the quality of the meat can be improved, and the occurrence rate of the PSE meat can be reduced.

Description

technical field [0001] The invention relates to a fortified feed additive, in particular to a post-livestock fortified feed additive and a preparation method thereof, belonging to the technical field of feed additives. Background technique [0002] In pig breeding, body shape is the focus of people's attention. In addition to meeting people's visual needs, it is also one of the signs that reflect the health of pigs. In actual production, the body shape also has a greater impact on the price of live pigs. Directly affect the economic benefits of pig farms. In the past pig raising industry, people pursued fast growth and good body shape of pigs one-sidedly, which led to the abuse of clenbuterol hydrochloride (clenbuterol), ractopamine and other prohibited drugs in the pig raising industry. Negative impacts include the deterioration of meat quality, seriously affecting human health, etc., which also hinders the export of commercial pork and fresh frozen pork and consumers' fea...

Problems solved by technology

[0003] For body shape problems, in addition to conventional methods such as adding meat quality improvers and physiological regulators, the current livestock stage feed additives mainly provide nutrition for animals from the perspective of maintenance and growth, but often fail to meet market demand. According to analysis, from the perspective of formulation, the main There are several problems in the following aspects: First, the setting of nutritional parameters is unreasonable: the nutritional parameters in most feed additive formulas are fine-tuned on the basis of previous research results, such as NRC standards and national standards. It lags behind the substantial increase in the production potential of pigs through breed improvement; the second is the particularity of the pig breeding environment in my country, and pigs face multiple pressures such as the environment and diseases. The anti-stress ability of live pigs has been screened, but it is undeniable that the anti-stress ability of live pigs has indeed been greatly reduced, and the current feed additive formulations mostly provide nutrition from the perspective of maintenance and growth nutritional requirements, while in animal immunity Special nutritional needs such as stress are less considered
