Description

Feed for improving immunity of black-feathered muscovy duck and preparation method thereof

technical field

The invention belongs to the field of feed, and in particular relates to a feed for improving the immunity of black-feathered Muscovy ducks and a preparation method thereof.

Background technique

Black-feathered Muscovy ducks are generally divided into brooding period, rearing period and egg-laying period according to their growth and development stages. Among them, the brooding period is the most difficult stage to raise black-feathered Muscovy ducks. The body temperature regulation function of black-feathered Muscovy ducks at this stage is not perfect. After 7-8 weeks, it has the ability to adapt to the temperature change of the external environment; the stomach volume is small, and the digestion ability is poor. There are not many enzymes, poor digestion ability; poor disease resistance. Due to poor adaptability to the external environment, ducklings are also weak in resistance to various diseases; It will reflect the pathological state. But at this stage, ducklings grow rapidly, have strong metabolism, and gain weight quickly. The weight of black-feathered Muscovy ducks at 2 weeks old is about 6 times that of newborns, and 4 weeks old is 12-15 times that of newborns. At the same time, the feathers of the black-feathered Muscovy ducks grew faster in the early stage, especially the feathers of the ducklings grew very fast, which was 4% of the body weight at the age of 3 weeks, increased to 7% at the 4th week, and then remained largely unchanged. The feathers of the black-feathered Muscovy duck will be removed and changed 3 times from hatching to before the start of production, respectively at the age of 4-5 weeks, 12-13 weeks and 18-20 weeks. The protein content in feathers is 80%-82%, which is 4-5 times that of meat and eggs. Therefore, black-feathered Muscovy ducks in the brooding period have high requirements for protein (especially sulfur-containing amino acids) in the diet.

But in the prior art, there is a lack of special feed developed according to the physiological characteristics of black-feathered muscovy duck ducklings, which causes difficulties in raising ducklings of black-feathered muscovy duck farmers, and the raised young muscovy ducks grow slowly, and the production performance cannot be brought into play. And the immunity of young muscovy ducks has not been improved, and it is easy to get sick or get sick in the early stage, which seriously affects the benefits and enthusiasm of muscovy duck breeding.

Contents of the invention

The object of the present invention is to provide a feed for improving the immunity of black-feathered muscovy ducks and a preparation method thereof, aiming at solving the problems of slow production and low immunity of muscovy ducks induced by feed.

The present invention is achieved in this way, a feed for improving the immunity of black-feathered muscovy ducks, comprising the following components in parts by mass: 100-120 parts of wheat bran, 80-100 parts of bean cake, 10-20 parts of lysine , 5-10 parts of tryptophan, 5-10 parts of methionine, 5-10 parts of angelica, 10-20 parts of Youtuncao, 1-2 parts of Bacillus, 1-2 parts of lactic acid bacteria, 1-2 parts of vitamin A, 1 ~2 parts of vitamin E, 1~2 parts of vitamin C.

Preferably, the feed also includes 9-10 parts by mass of soybean oil.

The present invention further provides a method for preparing the above-mentioned feed for improving the immunity of black-feathered muscovy ducks, which is obtained by grinding and mixing the raw materials. The raw materials include: 100-120 parts of wheat bran, 80-100 parts of bean cake, 10-20 parts of Lysine, 5-10 parts of tryptophan, 5-10 parts of methionine, 5-10 parts of Chinese angelica, 10-20 parts of Youtuncao, 1-2 parts of Bacillus, 1-2 parts of lactic acid bacteria, 1-2 parts of vitamins A. 1-2 parts of vitamin E, 1-2 parts of vitamin C; or, the raw materials include: 100-120 parts of wheat bran, 80-100 parts of bean cake, 10-20 parts of lysine, 5-10 parts of color Amino acid, 5-10 parts of methionine, 5-10 parts of angelica, 10-20 parts of Youduncao, 1-2 parts of Bacillus, 1-2 parts of lactic acid bacteria, 1-2 parts of vitamin A, 1-2 parts of vitamin E, 1 to 2 parts of vitamin C and 9 to 10 parts of soybean oil.

Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects: the present invention can meet the requirements of the black-feathered Muscovy duck by adding amino acids, Angelica sinensis, Grass, Bacillus, lactic acid bacteria, and vitamins to the diet of the black-feathered Muscovy duck. Muscovy ducks have different nutritional requirements in different growth and physiological periods. The nutrition is comprehensive, and no other special feed is needed. It can effectively improve the blood circulation of ducks, enhance their physique, and improve immunity, thereby reducing feeding costs and improving breeding benefits.

Effect example

In order to verify the feeding effect of the present invention on ducklings, the present invention has carried out a 45-day feeding test in a duck farm. The experiment adopted a single-factor comparative experimental design, and 800 healthy young Muscovy ducks about 1 day old were randomly divided into an experimental group and a control group in the duck house, and each group included 3 repetitions. The ration of test group 1 is the feed 1 prepared by the embodiment 1 of the present invention; the ration of the test group 2 is the feed 2 prepared by the embodiment 2 of the present invention; the ration of the test group 3 is the feed 3 prepared by the embodiment 3 of the present invention ; The diet of the control group was a commercially available product of the same kind.

The experimental group 1, 2, 3 and the control group were fed ad libitum. The immunization program during the trial was as follows:

age vaccination dose Instructions 7 ND+IBH 1.0 head portion Nasal drops, eye drops 14 IBD 1.0 head portion drip tip twenty one ND+IBH 1.6 servings Nasal drip 25 IBD 1.6 servings drip tip

On the 17th day, 27th day, 37th day, and 47th day of the test, blood was collected from the pterygoid vein, and the NDV antibody level was measured by the NDV hemagglutination inhibition test (HI), and the average value was calculated as a sign of the level of the NDV antibody level. At the same time, agar diffusion test (AGP) was used to detect the positive rate of IBDV serum, which was used as an index to judge the level of IBDV antibody.

The test results are shown in Table 1, and the results show that:

1. Body weight at 45 days: the average body weight of test groups 1, 2, and 3 increased by 11.31% compared with the control group;

2. The increase in the weight of animal immune organs is caused by the growth and division of its own cells. The increase in weight indicates that the immune function of Muscovy duck body is improved, and the decrease in weight indicates that the immune status of the body is getting worse. The weight of the thymus of the 45-day-old young muscovy ducks of test groups 1, 2, and 3 increased by 89.6% compared with the control group;

3. The weight of the 45-day-old bursa increased by 19.19% compared with the control group;

4. The average death rate of 45-day-old ducklings in test groups 1, 2, and 3 was 1.0%, and that of the control group was 6.4%, which was 5.4% lower than that of the control group.

5. It can be seen from Table 2 that there is no significant difference in the NDV antibody levels of ducklings in each group 10 days after the first immunization, indicating that the levels of maternal antibodies in each group are close. Antibody titers in all groups decreased at 6 days after the second immunization. With the prolongation of time, the titer of HI antibody in the serum gradually increased, and the test group was higher than the control group.

6. As can be seen from Table 3, the positive rate of each treatment group was very low at the age of 17 days. The positive rate began to increase at the age of 37 days, and the positive rate increased rapidly after the 37th day of age, among which the positive rates of test groups 1, 2, and 3 all reached 100%. It illustrates the promotion effect of the experimental group on the immunity of young muscovy ducks.
