Description

Technical Field

[0001] The present invention relates to the technical field of broiler breeding, and in particular to a breeding method for improving the nutritional value of broiler muscles. Background Art

[0002] With the improvement of economic level, people's lives have shifted from pursuing food and clothing to pursuing the intrinsic quality of products. Green, safe, nutritious and healthy food is the general trend; and chicken has become an indispensable meat on people's daily tables because of its delicious meat. In addition, chicken has significant therapeutic effects on chronic malnutrition, edema, hepatitis, gastritis and other diseases, and has the advantages of thin skin, tender meat, and a fresh and delicious flavor. It is the best edible supplement for middle-aged and elderly people, pregnant women and cardiovascular patients. Therefore, people's demand for chicken is increasing.

[0003] While traditional chickens are safe and reliable, they are often in short supply. While current chicken farms meet this demand, they overemphasize production efficiency and neglect the stabilization or improvement of meat quality, resulting in a decline in the quality and flavor of the chicken. Some unscrupulous businesses even inject chickens with hormones to maximize profits, leading to food safety issues.

[0004] Therefore, it is difficult to find broilers with good meat flavor, high production efficiency and high nutritional value in the market, which cannot meet the people's growing needs for a better life and also seriously affects the development of the broiler industry.

[0005] Therefore, providing a breeding method that can improve the nutritional value of broiler muscle has become an urgent problem to be solved. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a breeding method for improving the nutritional value of broiler chicken muscle, which specifically includes the following steps:

[0030] Step 4: Stocking management

[0031] The stocking density is 100-200 chickens per mu. Broilers are released after the first feeding each day and continue to be released for 2-2.5 hours after the last feeding before returning to the henhouse. Mechanical equipment, such as robot dogs, are used to chase broilers in the broiler area every day for 10-15 minutes each time, an average of 8-10 times a day. Live insects are added to the broiler area after the end of each day.

[0032] Preferably, the density of live insects in the stocking site is 15-25 / m 2 , the living insects include grasshoppers, crickets and earthworms in any proportion.

[0033] Step 5: Prevent pests and diseases

[0034] Chickens aged 0-5 days: add sucrose and glucose to feed every day;

[0035] 5-10 day old chickens: Add antibiotics to feed II every 2-3 days;

[0036] Chickens ≥11 days old: add Chinese herbal medicine powder to feed every 3 days;

[0037] During the period of free-range broiler farming, remove excrement from the chicken house, disinfect the chicken house with oxalic acid, and disinfect the air with alcohol spray.

[0038] Preferably, the mass fraction of the sucrose in the feed one is 4-5%, and the mass fraction of the glucose in the feed one is 3-4%;

[0039] The mass fraction of the antibiotic in feed 2 is 0.1-0.3%;

[0040] The mass fraction of the Chinese herbal medicine powder in the feed three is 1-2%.

[0041] The amount of oxalic acid used is 100-150g / m 2 The alcohol spray dosage is 50-100ml / m 3 , the volume fraction of the alcohol is 75%.

[0042] Most preferably, the antibiotics include penicillin and oxytetracycline in a mass ratio of (1-2):(1-2); the Chinese herbal medicine powder includes artemisia annua powder, licorice powder and ginger powder in a mass ratio of 5:3:1.

[0043] The present invention has the following advantages:

[0044] (1) Choline chloride can promote fat metabolism to avoid fatty liver caused by excessive fat, reduce the digestive burden of broilers, improve feed utilization to produce more lean meat, and improve the nutritional value of muscle.

[0045] (2) Carrots, walnut powder and almond powder can increase the unsaturated fatty acid content of chicken. Walnut powder and almond powder can also increase the selenium content in the muscle, thereby improving the nutritional value of chicken.

[0046] (3) Mulberry leaves are rich in cellulose, which can promote the digestive system function of chickens and avoid indigestion, thereby reducing ammonia and odor in feces and improving the chicken house environment; mulberry leaves are also rich in silk protein, which helps to improve the immunity of chickens, inhibit the growth of various bacteria and viruses, promote the body's metabolism and blood circulation, improve the health level of chickens, and thus increase the nutritional value of muscles.

[0047] (4) A lower stocking density is used during stocking. On the one hand, it can ensure that the chickens have enough space to move around and exercise, thereby improving muscle toughness, reducing excessive fat deposition, achieving firm muscles, moderate fiber thickness, tender meat, and greatly improving the quality of chicken.

[0048] (5) Dandelion and purslane are widely used antibacterial herbs. Planting them in free-range areas allows chickens to eat freely. When combined with the addition of Chinese herbal medicines to feed, they can enhance the chickens’ immunity, keeping them healthy and active, and preventing them from being infected by parasites and diseases.

[0049] (6) Chasing broilers regularly every day can significantly increase the activity of the chickens, speed up the consumption of food, increase the content of myofibrils in the meat, increase the degree of cross-linking between collagen molecules, improve the nutritional value of the muscles, make the meat firm, and increase the chewing feel.

[0050] (7) Restricting feeding, reducing light exposure, and increasing feeding times before 21 days of age can reduce early growth rate, allowing bones and muscles to fully develop to adapt to the needs of rapid growth in the middle and late stages, increase muscle content, and reduce fat content.

[0051] (8) The present invention adopts a feeding method of small meals and frequent feeding. The amount of feed fed in the present invention is less than the normal level, but because the chickens have enough space to eat freely, they can take wheat and live insects in the field as feed to supplement, which can greatly improve the flavor and nutritional value of the chicken.

[0052] (9) Using oxalic acid to disinfect the chicken house can effectively remove ammonia in the chicken house; excessive ammonia concentration can cause damage to the chicken's respiratory system and even cause pneumonia, and can also reduce feed intake and growth rate. DETAILED DESCRIPTION

[0082] Comparative Example 2

[0083] The difference from Example 1 is that this comparative example does not use a robot dog to chase broiler chickens.

[0084] Comparative Example 3

[0085] The difference from Example 1 is that the feed of this comparative example does not contain choline chloride.

[0086] Comparative Example 4

[0087] The difference from Example 1 is that the feed in this comparative example does not contain walnut powder and almond powder.

[0089] The difference from Example 1 is that the feed in this comparative example does not contain mulberry leaves.

[0090] Test Example 1

[0091] Among the broiler chickens raised in Example 1 and Comparative Examples 1-6, 100 male and female broiler chickens aged 60 days were randomly selected and sent to a local slaughterhouse for slaughter. The chicken meat was sent to a local testing agency for meat quality testing, and the average value was taken. The results are shown in Table 1.

[0092] Table 1

[0093]

[0094] As shown in Table 1, the broilers bred in Example 1 weighed more than those in Comparative Examples 1-2 and 4-5, although slightly less than Comparative Example 3. However, since Comparative Example 3 was not fed choline chloride, the intramuscular fat content was too high and the nutritional value was significantly reduced. Comparative Example 1 did not plant dandelions, horsetail, and wheat, and did not supplement live insects, resulting in a significant increase in the disease rate of the chickens and a slight decrease in muscle content. Comparative Example 2 did not chase the broilers, resulting in a significant decrease in the activity level of the broilers, a significant decrease in muscle content, and a significant decrease in nutritional value. Comparative Example 4 did not feed walnut powder and almond powder, resulting in a decrease in selenium content in the muscles and a decrease in nutritional value. Comparative Example 5 did not feed mulberry leaves, resulting in an excessive burden on the chickens' digestive system, a slight increase in the disease rate, a slight decrease in muscle content, and a decrease in nutritional value.

[0095] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention.
