本申请要求2019年5月30提交的中国专利申请201910462502.9号以及2019年7月8日提交的中国专利申请201910609010.8号的优先权,通过引用将两篇专利申请的内容全部并入本文,用于所有目的。This application claims the priority of Chinese patent application No. 201910462502.9 filed on May 30, 2019 and Chinese patent application No. 201910609010.8 filed on July 8, 2019. The contents of the two patent applications are incorporated herein by reference for all purpose.
本申请大体涉及动物饲料产品领域;更具体而言,本申请涉及适于动物饲养、特别是动物病防治的饲用组合物及其制备方法和应用。The present application generally relates to the field of animal feed products; more specifically, the present application relates to a feed composition suitable for animal feeding, especially animal disease control, and a preparation method and application thereof.
畜禽饮水或饲料的酸化、霉变以及病原微生物的滋生易引起畜禽中毒,影响畜禽生长,降低畜禽机体抵抗力、甚至引发疫病的爆发,给畜牧业发展造成严重的经济损失。The acidification, mildew and growth of pathogenic microorganisms in livestock and poultry drinking water or feed can easily cause livestock and poultry poisoning, affect the growth of livestock and poultry, reduce the resistance of livestock and poultry, and even cause disease outbreaks, causing serious economic losses to the development of animal husbandry.
为了解决上述问题,研发人员进行了不断的努力和探索,研发出一些产品,但是仍然无法满足畜牧业生产的需要。因此,迫切需要开发新的、经济有效的用于畜禽饮水或饲料的防酸化、防霉变和/或防病原微生物的产品,促进畜牧业经济的可持续发展。In order to solve the above problems, R&D personnel have made continuous efforts and explorations to develop some products, but they still cannot meet the needs of animal husbandry production. Therefore, there is an urgent need to develop new, cost-effective and anti-acidification, anti-mildew, and/or anti-pathogenic microorganism products for livestock and poultry drinking water or feed to promote the sustainable economic development of animal husbandry.
此外,诸如病毒、细菌等的致病微生物感染是长期困扰动物饲养的问题,也是产业内一直面对的挑战和研究热点。John J.Kabara于1966年发现饱和脂肪酸中中链脂肪酸月桂酸(C
12)的杀菌能力较强,而单不饱和脂肪酸中棕榈油酸(C
16:1)的杀菌能力更为优异。Himarsson等(2006年)进一步证实了这一点,并且发现月桂酸在酸性环境下对Visna病毒的抑制作用更强。此外,还有报道证实,基于短链脂肪酸(如丁酸)的物质能抑制革兰氏阴性细菌如沙门氏杆菌、大肠杆菌。
In addition, the infection of pathogenic microorganisms such as viruses and bacteria is a problem that has plagued animal feeding for a long time, and it is also a challenge and research hotspot that the industry has been facing. John J. Kabara discovered in 1966 that the medium-chain fatty acid lauric acid (C 12 ) in the saturated fatty acid has a stronger bactericidal ability, while the palmitoleic acid (C 16:1 ) in the monounsaturated fatty acid has a better bactericidal ability. Himarsson et al. (2006) further confirmed this point and found that lauric acid has a stronger inhibitory effect on Visna virus in an acidic environment. In addition, there are reports confirming that substances based on short-chain fatty acids (such as butyric acid) can inhibit Gram-negative bacteria such as Salmonella and Escherichia coli.
基于中、短链脂肪酸的抗微生物制剂开发具有良好的前景,也是本领域亟需的。The development of antimicrobial preparations based on medium and short-chain fatty acids has good prospects and is also urgently needed in this field.

Butyrate, tributyrin and its derivatives can release butyric acid in the digestive tract, repair damaged intestinal mucosa, and enhance the barrier function of the digestive tract. Glycerol laurate and its derivatives can resist pathogenic microbial infections It has a preventive effect on potential pathogenic microorganisms. The low pH value is beneficial to inhibit the mildew of livestock and poultry drinking water or feed and the growth of pathogenic microorganisms. If it can make it contain butyrate, butyrin and butyrin The feed emulsion composition of glyceryl laurate, lauric glyceride derivatives or mixtures thereof is stable at a low pH value (for example, a pH value of 2-6), and can be used for livestock and poultry. Provide good drinking water or feed with natural anti-virus and anti-pathogenic effects. In contrast, conventional fatty acid ester emulsions are unstable under low pH conditions and cannot maintain low pH values after being diluted 100-1000 times with water. In addition, although butyrate and its derivatives have many biological benefits, butyrate and its derivatives usually have poor odor and taste, and adding them directly to feed will cause palatability problems. In view of the above technical problems, the inventor of this application has established various inventions of this application through research, and each invention of this application can solve at least one of the above technical problems, and in some cases also has other advantages.
此外,本申请的发明人基于脂肪酸、特别是基于丁酸(短链脂肪酸)和月桂酸(中链脂肪酸)的化合物在动物抗病方面进行了深入研究,发现丁酸甘油酯和聚甘油月桂酸酯联合使用具有优异的效果。此外,鉴于月桂酸及其酯类通常呈固态,不适合动物饮水添加或直接灌服,本申请的发明人还进一步开发出更方便给予动物的饲用组合物制剂,例如,以酸性乳液的形式。由此,建立了本申请的各项发明。In addition, the inventors of the present application have conducted in-depth research on animal disease resistance based on fatty acids, especially compounds based on butyric acid (short-chain fatty acid) and lauric acid (medium-chain fatty acid), and found that butyric acid glycerides and polyglyceryl lauric acid The combination of esters has excellent effects. In addition, in view of the fact that lauric acid and its esters are usually solid and are not suitable for animal drinking water addition or direct administration, the inventor of the present application has further developed a feed composition formulation that is more convenient to administer to animals, for example, in the form of an acid emulsion . Thus, various inventions of this application have been established.

根据图1和图2的结果可知,本实施例的细胞评价模型是成功的。According to the results of Figure 1 and Figure 2, it can be seen that the cell evaluation model of this example is successful.
由于病毒复制会受到细胞自身增殖、生长情况的影响,因此对于病毒抑制功效的评价需要考虑这方面的结果。Since virus replication is affected by the proliferation and growth of cells, the evaluation of virus inhibitory efficacy needs to consider the results of this aspect.
月桂酸的3个组不能实现同时保持较好的细胞形态学且实现有效病毒抑制。The three groups of lauric acid could not achieve while maintaining good cell morphology and achieving effective virus suppression.
月桂酸单甘脂1.92mg/ml和0.96mg/ml浓度组存在细胞毒性,0.384mg/ml浓度组的细胞毒性不明显,并且存在一定的病毒抑制效果。There was cytotoxicity in the 1.92mg/ml and 0.96mg/ml concentration groups of lauric acid monoglyceride, and the 0.384mg/ml concentration group had no obvious cytotoxicity, and there was a certain virus inhibitory effect.
聚甘油月桂酸单甘酯3mg/ml和1.5mg/ml浓度组存在细胞毒性,0.6mg/ml浓度组的细胞毒性不明显,并且存在一定的病毒抑制效果。The 3mg/ml and 1.5mg/ml concentration groups of polyglyceryl laurate monoglyceride showed cytotoxicity, and the 0.6mg/ml concentration group had no obvious cytotoxicity, and there was a certain virus inhibitory effect.
酸性乳液40mg/ml浓度组无明显细胞毒性且实现了强病毒抑制效果,100mg/ml浓度组仅具有轻微细胞毒性且实现了强病毒抑制效果。The acid emulsion 40mg/ml concentration group has no obvious cytotoxicity and achieves a strong virus suppression effect, while the 100mg/ml concentration group has only slight cytotoxicity and achieves a strong virus suppression effect.
综合以上结果,酸性乳液在抗ASFV方面的作用和效果大大优于月桂酸、月桂酸单甘脂和聚甘油月桂酸单甘酯。值得注意的是,按照等月桂酸浓度折算,酸性乳液40mg/ml浓度组是月桂酸、月桂酸单甘脂和聚甘油月桂酸单甘酯的最高浓度组的2倍,这提示酸性乳液的配制能够显著降低月桂酸的细胞毒性。本申请开发的乳液中联合使用了丁酸甘油酯和聚甘油月桂酸单甘酯并将其制备成酸性形式,这样的产品实现了优异的抗病毒结果。Based on the above results, the effect and effect of acid emulsion in anti-ASFV is much better than lauric acid, lauric acid monoglyceride and polyglycerol lauric acid monoglyceride. It is worth noting that according to the equivalent lauric acid concentration, the 40mg/ml acid emulsion concentration group is twice the highest concentration group of lauric acid, lauric acid monoglyceride and polyglycerol lauric acid monoglyceride, which suggests the preparation of acid emulsion Can significantly reduce the cytotoxicity of lauric acid. The emulsion developed in the present application combines butyric acid glyceride and polyglyceryl lauric acid monoglyceride and prepares it into an acid form. Such a product achieves excellent antiviral results.
