Background technique

Since the 1980s, a large number of chemically synthesized feed additives, such as antibiotics and growth-promoting hormones, have been widely used in feeds, causing a series of problems such as drug resistance of pathogenic microorganisms, decreased animal immunity, and drug residues that endanger human health. With the popularization of relevant knowledge, people's awareness of food safety has been continuously strengthened, and more and more attention has been paid to the quality, hygiene and safety of animal products. Such feed antibiotics and some chemical additives are bound to be phased out with the development of society. The development of safe and green new feed additives with high efficiency, no drug residues and no pollution is the inevitable result of social development.

With the continuous in-depth research of new antibiotic substitutes in livestock and poultry production, researchers found that plant essential oils have the characteristics of antibacterial, antiviral, no residue, multi-functionality, anti-stress and anti-oxidation, so they are applied to livestock and poultry. In the production of poultry feed, it can be used as a substitute for antibiotics, which is in line with the development direction of healthy livestock and poultry breeding. Plant essential oils can effectively replace antibiotics, promote animal growth, improve feed conversion efficiency, and reduce the incidence of diseases. Feed additives.

However, plant essential oils are unstable and volatile, which makes them easy to lose and difficult to pass through the digestive tract of animals in the process of feed processing.

Application Example 1

Select healthy and disease-free, hatched chickens in the same batch, randomly divided into 4 groups, each group repeated 3 times, each repetition 60, respectively fed commercially available common antibiotic premix and the present invention containing plant essential oil. Poultry feed, management and immunization methods during the feeding period are carried out in accordance with the "Technical Regulations for Chicken Feeding Management". The test starts from the 3-week-old chick and ends at the 15-week-old age. The chicken infection rate and average weekly weight gain within 12 weeks of the feeding cycle are shown in Table 1. Show.

Table 1 Infection rate and average weekly weight gain of chickens during the feeding period

It can be seen from Table 1 that the chicks fed with the common antibiotic premix generally develop disease in the fourth week, the incidence rate is 13-15%, and the main symptoms are: loss of appetite, fear of cold gathering, closed eyes Hanging head and pulling white thin feces at the same time, it adheres to the anus. If these symptoms are not treated in time, the chicks will die. On the other hand, for chicks fed by the animal feed containing plant essential oil of the present invention, the onset time is delayed by 2-3 weeks, and the morbidity rate is reduced to less than 5%, and the morbidity rate is significantly reduced.

In addition, can also find out from table 1, adopt the chick that the poultry and livestock feed containing plant essential oil of the present invention is fed, the growth rate of chicken is slower than the growth rate of common type antibiotic premix feeding, but the difference is not big. The growth-promoting effect of the animal feed containing the plant essential oil of the present invention is better.

Application Example 2

The commercially available common antibiotic premix and the animal feed containing plant essential oil of the present invention are used to feed the healthy pigs of the same breed of a pig farm, with a body weight of 25±2 kg, and are divided into pens with similar body weight and half male and female In principle, they were randomly divided into 4 groups, each group was repeated 3 times, each repetition was 6 heads, and the test time was 30 days.

(1) Weigh the pigs on an empty stomach on the 1st day and the 30th day respectively in the morning, and count the average daily weight gain (kg) of the pigs after feeding each group of feeds, as the growth rate index, see Table 2 for details.

Table 2 Average weight gain and average daily gain of pigs

As can be seen from Table 2, the average daily weight gain of Examples 1-5 and the average daily weight gain of the common antibiotic premix are slightly lower, illustrating that the growth rate of pigs fed with the plant essential oil-containing livestock feed of the present invention is higher than that of common antibiotic premixes. The growth rate of pigs fed with the type antibiotic premix is slower, but the difference is not large, which shows that the growth-promoting effect of the animal feed containing plant essential oil of the present invention is better.

(2) Record the morbidity and death situation and quantity of growing pigs throughout the test period, see Table 3 for details.

Table 3 Morbidity and mortality of pigs

As can be seen from Table 3, the pigs fed with the animal feed containing plant essential oil of the present invention have no morbidity and death, and have strong immunity.

Above-mentioned test shows: adopt the poultry and livestock feed containing plant essential oil of the present invention to feed, and the growth rate of poultry and livestock is slower than the growth rate fed with common antibiotic premix, but the difference is not large, so the slaughtering cycle of poultry and livestock can be appropriately delayed , which is conducive to the improvement of the quality of livestock products. The livestock feed containing the plant essential oil can improve the immunity of the livestock and poultry, the fed livestock and poultry have a good mental state, are greedy and active, have a wild nature, have healthy muscles and bright hair, have strong disease resistance, and are resistant to swine erysipelas and swine high fever. , poultry cholera and other epidemic diseases of livestock and poultry have a good preventive effect.
