Problems solved by technology

[0018] In order to solve the problems in the above-mentioned prior art, the present invention proposes the application of protocatechuic acid as a feed additive in livestock and poultry breeding, which is used to promote the growth and development of animals, improve feed conversion rate, improve carcass quality and meat flavor, and comprehensively enhance The immune function of animals and the ability to defend against diseases have overcome the toxic and side effects of chemically synthesized organic acids and food safety hazards, and have avoided the shortcomings of complex ingredients, inconvenient use, and difficult control of quality standards for Chinese herbal medicine additives. The research and development prospects are optimistic and the clinical applications are broad.

Embodiment 1

[0027] Example 1, the application of protocatechuic acid as a feed additive in piglet breeding.

[0028] The basic diet was provided by Nanjing Hejia Jisheng Agriculture and Animal Husbandry Development Co., Ltd. The composition and nutritional level of the basic diet are shown in Table 1. Protocatechuic acid and citric acid provided by China Institute of Pharmaceutical and Biological Products were used as feed additives, and they were mixed evenly with the basal diet at a mass ratio of 1:100, and the piglets were tested in vivo.

[0029] Table 1 Basic diet composition and nutritional level (air-dried basis)

[0030]

[0031] Thirty healthy ordinary-grade “Du × Da × Chang” triple cross weaned piglets, 50 days old, were purchased from the Jiangpu Experimental Pig Farm of Nanjing Agricultural University. After adapting to the environment, they were randomly divided into 3 groups, 10 in each group, half male and half female. The basal diet without protocatechuic acid (blank ...

[0036] Experimental Example 2: Effects of protocatechuic acid on growth, immune performance, carcass and muscle quality of broiler chickens

[0037] 1. Experimental animals:

[0038] Experimental animals AA broiler chickens were purchased from a broiler chicken breeding base in Nanjing City, Jiangsu Province. One-day-old chicks were routinely raised to 21 days old, and 270 healthy broiler chickens with similar weight were selected.

[0039] 2. Experimental drugs:

[0040] The basic diet adopts corn-soybean meal type diet, and the formula is designed according to the NRC (1994) broiler feeding standard. Its specific formula and nutritional level are shown in Table 2.

[0041] Table 2 Basic diet composition and nutritional level (air-dried basis)

[0042]

[0043] The full-price commercial feed for broilers was purchased from a feed factory in China. The protocatechuic acid and citric acid provided by China Institute of Pharmaceutical and Biological Products were used as ...

Abstract

The invention provides application of protocatechuic acid as a feed additive in livestock breeding, the protocatechuic acid is used for promoting the growth and development of animals, improving the feed conversion rate, improving ketone body quality and meat quality, comprehensively enhancing animal immunization function and capacity of preventing disease; the toxic and side effect of chemically synthesized organic acid and food potential risk are overcome, the disadvantages that the Chinese herbal medicine additives are complex in component, the use is inconvenient, and the quality standard is hard to control are avoided, the research and development prospect is positive, and the clinical application is wide.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, and in particular relates to the application of protocatechuic acid as a feed additive in livestock and poultry breeding. Background technique [0002] With the rapid development of the breeding industry and the feed industry, people have gradually realized that adding antibiotics, hormones, and chemical synthetic drugs to animal feed can promote animal growth and reduce disease occurrence, but long-term use of these drugs will cause pathogenic microorganisms to develop drug resistance Sexuality, product drug residues and environmental pollution, etc., seriously threaten human health, and at the same time affect the export of agricultural and sideline products in my country. [0003] In the past ten years or so, with the prohibition of feed antibiotics in the European Union, the research and development of AGP (growth-promoting antibiotics) substitutes has been accelerated. Organic acids are st...
