Description

Antibiotic-free premix for later-stage feed of dry-raising meat ducks and application method of antibiotic-free premix
Technical Field
The invention belongs to the technical field of animal feeding, and particularly relates to an antibiotic-free premix for a later-stage feed of a dry-fed meat duck and a use method thereof.
Background
Duck meat is an indispensable meat food in daily life of people, is also a delicious dish, is suitable for nourishing, is a main raw material of various delicious dishes, and is a main raw material of ancient people: the duck meat is beautiful, and the ducks in the house are loved to eat. The duck meat has higher protein content than the livestock meat, moderate fat content, uniform distribution and good taste. The vitamin B and vitamin E contained in the meat can resist beriberi, neuritis and various inflammations effectively and resist aging compared with other meats. Duck contains rich nicotinic acid, which is one of two important coenzyme components in human body and has protecting effect on heart diseases, such as myocardial infarction, etc.
Meat duck farming is one of the traditional farming. The addition of antibiotics in feeds has become a habit of livestock breeding, however, the long-term use of antibiotics causes serious damage to livestock: firstly, drug-resistant bacteria are generated in animals, so that cellular immunity and humoral immunity are inhibited, the immune cell function of the animals is seriously damaged, the immunity and disease resistance of the animals are reduced, and even the immunity is failed; secondly, excessive antibiotics used in feed, additives and veterinary drugs can enter human bodies through food chains, so that people can indirectly contact the antibiotics, the effect of treatment with the antibiotics disappears when the human bodies are ill, and meanwhile, the antibiotics destroy intestinal microorganisms and influence the digestion capacity of animals on nutrient substances and the growth performance of the animals; third, certain antibiotics themselves have deleterious effects such as streptomycin, kanamycin, gentamicin, polymyxin, and the like.
The abused antibiotics can cause pathogenic bacteria to generate drug resistance, cause animal intestinal flora imbalance, reduce immunity and influence production performance and product quality. The microecological live bacteria become a relatively ideal product for replacing antibiotics. However, some common microecologics in the current market are still limited in popularization and application due to the influence of temperature, pH value, intolerance to antibiotics and the like.

Feeding experiment
1. Test method
The experiment selects 4000 feather cherry valley ducks (male and female halves) with 14-day age and body weight of about 640g (P > 0.05) to carry out corresponding immunization program.
Experimental group: the bulk materials prepared in examples 1 to 5 of the present invention;
control group: the bulk materials prepared in comparative examples 1 to 5;
the formula of the basic large material comprises the following steps: 330 parts of corn, 215 parts of barley, 50 parts of wheat, 120 parts of 43% soybean meal, 75 parts of brewer's grains, 50 parts of corn fiber, 50 parts of corn germ meal, 20 parts of palm kernel meal, 40 parts of soybean oil, 10 parts of bentonite, 12 parts of stone powder and 8 parts of calcium hydrophosphate.
2. The experimental ducks were randomly divided into 10 groups, 5 experimental groups, 5 control groups, 2 replicates each, and 200 feathers each. The raising mode is dry raising in a ground fence, the raising mode has the functions of preventing sunshine and rain, and has the measures of heat preservation and cooling, each repeated group is independently fed, and test ducks eat and drink water freely during the test. Pre-test for 7 days and formal test period for 21 days. During the test, the room temperature is controlled between 22 ℃ and 25 ℃, the breeding and the related vaccine immunization are carried out according to the conventional breeding mode, and the total feed consumption of each repetition is recorded every day. The influence of each feed on the production performance of the meat ducks is detected by counting the indexes of 14-day-old meat ducks, 42-day-old meat ducks, death and death numbers, survival rate, total weight gain, total feed consumption and feed-meat ratio, so that scientific basis is provided for production and utilization. The results of the effect of each bulk material on the performance index are shown in the following table.
Figure BDA0003321948110000131
Figure BDA0003321948110000141
From the above table, example 5 is the best example, and each index is improved compared with comparative example 1, and it can be seen that the antibiotic-free premix formula can completely replace the antibiotic premix formula in production practice. The indexes of the examples 5, the comparative examples 2, the comparative examples 3 and the comparative examples 4 are all improved compared with the comparative example 2, and the synergy of the examples 5 relative to the comparative examples 5 is more than 10% higher than the sum of the synergy of the comparative examples 2-4 relative to the comparative example 5 in the indexes of the 42-day-old weight, the total weight and the total consumption 3. This is due to: the three components of the macleaya cordata powder, the tributyrin and the gamma-aminobutyric acid, wherein the tributyrin mainly supplies energy to the intestinal tract, repairs the intestinal tract and resists stress, and can be matched with digestive enzymes to improve the digestibility of nutrient substances, promote the growth of animals and finally realize the replacement of growth-promoting antibiotics in feed; the gamma-aminobutyric acid maintains the central regulation of various systems of the organism, and the growth hormone secretion is increased and the growth is promoted by influencing the growth of pituitary glands, thyroid glands and the like and the secretion of hormone; in particular, the pancreatic secretion of pancreatic lipase can be promoted, so that the decomposition of tributyrin is promoted; the macleaya cordata powder mainly plays roles in regulating intestines, resisting inflammation and promoting growth, the main component of the macleaya cordata powder is sanguinarine, the macleaya cordata powder is not easy to be absorbed by a human body, more than 98% of the macleaya cordata powder is discharged in a raw material form, and the rest of the macleaya cordata powder is metabolized by the liver, acts on the digestive tract, is absorbed by the gastrointestinal tract, enters plasma, can improve the antioxidant capacity of the human body, and has no influence on the mucous epithelium of small intestine; the tributyrin and the gamma-aminobutyric acid can regulate intestinal tracts, can provide energy for organisms and stimulate hormone secretion, thereby promoting absorption and digestion of sanguinarine.
In conclusion, the overall production performance of the test group is superior to that of the control group, the weight gain effect is obviously improved, the disease resistance is enhanced, the feed conversion ratio is reduced, and the survival rate is improved.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
