Problems solved by technology

Although there are patents on the promotion of broiler growth by organic acids or plant essential oils, there are many types of organic acids and essential oils, and the reported results are inconsistent.
At present, there is still a lack of research data on the feeding effects of different types of organic acids and plant essential oils instead of antibiotics on broiler growth, organ development and anti-stress response

Embodiment 1

[0028] A broiler feed additive is provided in this embodiment. The active ingredients of organic acids are 50% of benzoic acid, 3% of calcium formate, 1% of fumaric acid, and the rest are carriers, and the carrier components are palm oil and silicon dioxide; The active ingredients of the mixture are 25% thymol, 25% carvacrol, and the rest are anti-caking agent (precipitated silicic acid) and carrier (comprising fatty acid, monoglyceride and diglyceride). The amount of organic acid added to broiler feed was 1.5g / kg. The amount of plant essential oil added in broiler feed is 30mg / kg. The compound of organic acid and essential oil added in broiler feed was 1.5g / kg organic acid and 30mg / kg essential oil.

[0029]This embodiment also provides broiler feed and control with broiler feed additives, and is applied to broiler breeding. Organic acid + essential oil compound group: add 1.5g / kg organic acid and 30mg / kg plant essential oil to the basic diet.

Embodiment 2

[0039] Example 2 essential oils and organic acids instead of antibiotics promote broiler growth performance

[0040] The growth function of broiler chickens was tested using the feeds of each group in Example 1, and the growth function results of broiler chickens are shown in Table 2.

[0041] Table 2 Analysis of the effects of essential oils and organic acids instead of antibiotics on the growth function of broilers

[0042]

[0043] Note: In each table, SEM: standard deviation of the mean value; different letters on the shoulders of a and b represent significant differences (P<0.05).

[0044] It can be seen from Table 2 that the addition of organic acids, plant essential oils and compounds to broiler diets can significantly increase the average daily gain of broiler chickens in the late stage (22nd to 42nd days) and the whole period (1st to 42nd days) of the experiment. And organic acids can replace antibiotics (chlortetracycline) to promote the growth of broilers.

[0045] Example 3 Effects of Organic Acids and Essential Oils Substituting Antibiotics on Broiler Organ Index

[0046] The viscera index of broiler chickens was tested using the feeds of each group in Example 1, and the results of the viscera index of broiler chickens are shown in Table 3-5.

Abstract

The invention relates to a broiler feed additive and application thereof. The broiler feed additive comprises plant essential oil and / or organic acid, wherein the plant essential oil comprises thymoland carvacrol; and the organic acid comprises benzoic acid, calcium formate and fumaric acid. The broiler feed additive containing the specific organic acid, the plant essential oil and the compound of the specific organic acid and the plant essential oil can replace antibiotics such as aureomycin and improve the growth and anti-stress capacity of broilers.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a broiler feed additive and its application. Background technique [0002] In recent years, the misuse of antibiotics not only makes bacteria resistant and reduces the immunity of poultry, but also causes endogenous and superinfection (due to the imbalance of flora) and residues in poultry products and the environment. Adding antibiotics to feed is now officially banned. Under modern intensive production conditions, broiler chickens also face many stresses during their growth and development, which may lead to growth retardation. In addition, broiler chickens may also face stress sources such as transportation and starvation, which may cause their body condition to decline before slaughter, resulting in serious body loss and decreased antioxidant status, which will affect the quality of poultry meat. Therefore, finding safe and efficient growth promoters and anti-stres...
