Description

Technical Field

[0001] The invention relates to the field of meat goose breeding, in particular to a dry breeding method for Ding'an meat geese. Background Art

[0002] Goose farming is a traditional industry in my country's animal husbandry, and my country is also a major goose farming country. Geese require less energy and have a strong ability to adapt to the environment. Therefore, goose farming has the characteristics of low grain consumption and high economic benefits. It is deeply loved by farmers, and the scale of goose farming has gradually expanded. Ding'an goose is a local variety in Hainan Province. It is mainly produced in Ding'an County, Hainan Province. It is located in the northeast of Hainan Province, on the south bank of the middle and lower reaches of the Nandu River, at 110°7' to 110°31' east longitude and 19°31' north latitude. Ding'an goose has the advantages of medium size, fast growth rate, strong adaptability, and delicious meat.

[0003] Usually, meat geese are easily polluted by the breeding methods during traditional breeding, which leads to problems such as disease transmission and antibiotic use. At present, according to the herbivorous nature and adaptability of geese, the breeding methods of geese have been changed from traditional methods to ecological breeding methods. The ecological breeding methods of breeding geese under the forest have been developed, which not only solves the problem of weeding under the forest, but also saves feed, increases the amount of exercise for geese, and improves the quality of goose meat. However, ecological breeding also has problems such as pollution. At the same time, the stocking density is high, and it is not possible to fully take care of each meat goose, resulting in poor growth of some meat geese, which in turn affects the growth performance and health level of the overall meat geese. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a dry-rearing method for Ding'an goose meat geese to solve the above problems.

[0005] The technical solution of the present invention is achieved in this way:

[0006] A dryland breeding method for Dingan goose meat geese comprises the following steps:

[0007] S1 Establish an ecological breeding ground: Choose a shrub forest, build a goose house, set up a gentle slope, have a water trough and plant pasture on the gentle slope, use fences to surround it, and plant herbaceous plants along the periphery of the fences;

[0008] S2 Free-range: Free-range Ding'an geese aged 8-10 days are fed with compound feed 2-4 times a day; after spraying attractants on the pasture, graze for 2-3 hours, stimulate hunger for 2-3 hours, spray attractants on the herbaceous plants, scatter compound feed around the ecological breeding ground, and graze again for 3-4 hours;

[0009] S3 fattening: Release Ding'an geese to 30-32 days old, feed them with compound feed 3-4 times a day; spray attractants on the pasture, and feed them with compound feed once, and graze for 4-5 hours.

[0010] By feeding compound feed and spraying attractants on the pasture, combined with grazing and hunger stimulation, the breeding efficiency is improved; after the Ding'an geese are released to the age of 30-32 days, the fattening efficiency is improved by feeding compound feed, combining attractant geese with compound feed, and grazing methods; releasing Ding'an geese at the age of 8-10 days can avoid the complicated and low efficiency of the goslings' opening process. Selecting Ding'an geese at the age of 8-10 days helps to ensure that geese of the same physique are in the constructed suitable ecological breeding ground.

[0011] Further, the height of the shrubs is not less than 2m, the density of the shrubs is 75-85%; the slope is 18-22°; the pasture is chicory or oleander, the herb is an annual twining herb; the herb is morning glory; the stocking density is 8-11 / m 2 .

[0012] The invention sets a gentle slope with a water trough and planted grass, so that the geese can climb the slope to drink water and eat grass, which plays a role in exercising the legs and necks of the geese. At the same time, planting grass on the gentle slope can also prevent the geese from being trampled when grazing.

[0013] It is further specified that the attractant includes white cardamom, arrowroot and citronella; the attractant is diluted 6-8 times before use.

[0014] Arrowroot (Maranta arundinacea L.), widely grown in various tropical regions, has the effect of cooling and moistening the lungs.

[0015] Further, the mass ratio of the white cardamom, arrowroot and citronella is 0.5-0.8:2-4:2-4. The white cardamom is white cardamom essential oil, the arrowroot is arrowroot powder, and the citronella is citronella powder.

[0016] It is further explained that when the temperature is higher than 37℃, a water trough is temporarily placed under the gentle slope, and attractants are added to the trough to encourage the geese to drink more water.

[0017] Further explanation: in steps S2 and S3, the attractant is sprayed on the pasture between 9:00 and 10:00 in the morning.

[0018] A dryland breeding method for Dingan goose meat geese comprises the following steps:

[0019] S1 Establish an ecological breeding ground: Choose to build a goose house under a betel nut or rubber tree. The goose house is a net bed that includes an activity area and a feeding area. The activity area and the feeding area are separated by a door. There is a fence around the net bed, and herbaceous plants are planted along the fence.

[0020] S2 grazing: 8-10-day-old Ding'an geese are fed with compound feed 2-4 times a day; after spraying attractants on the herbaceous plants, graze for 2-3 hours, stimulate hunger for 2-3 hours, spray attractants on the herbaceous plants, and graze again for 3-4 hours;

[0021] S3 fattening: Release Ding'an geese to 30-32 days old, feed them with compound feed 3-4 times a day; spray attractants on the herbaceous plants, and feed them with compound feed once, and graze for 4-5 hours.

[0022] Further, the area of ​​the activity area is at least twice the area of ​​the feeding area; the herbaceous plant is morning glory; the stocking density is 8-11 / m 2 The attractant comprises white cardamom essential oil, arrowroot powder and citronella powder in a mass ratio of 0.5-0.8:2-4:2-4; the attractant is diluted 6-8 times before use.

[0023] It is further explained that the compound feed consists of the following feed in percentage by weight: 65-75% corn and the remainder silage.

[0024] Further, the silage is prepared from banana stems and leaves and Aspergillus sydowii.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention establishes an ecological breeding ground, adopts compound feed and attractants in combination with the stocking and fattening process, and constructs an ecological breeding method of dry-raising geese, which helps to avoid water pollution, reduce feces pollution and other problems, curb pollution sources, stimulate goose digestion and absorption, and increase feed intake. The geese harvested from the breeding are in good development, healthy and energetic, and are relatively consistent in size when they are released from the market.

The area of ​​the activity area is twice the area of ​​the feeding area. The periphery of the net bed is surrounded by a fence, and the annual winding herb morning glory is planted along the periphery of the fence so that the morning glory grows on the fence;

[0043] Establish an ecological breeding ground and set the stocking density at 10 / m 2 Ding'an geese aged 8-10 days were fed with compound feed three times a day. During the breeding process, attractants were sprayed on the nephrolepis at 9:00-10:00 in the morning. After grazing for 3 hours, the geese were driven back to the goose house for hunger stimulation for 3 hours, and attractants were sprayed on the morning glory and grazed again for 4 hours.

[0044] Ding'an geese are released into the wild until they are 30-32 days old, and are fed compound feed three times a day. At 9:00-10:00 a.m., attractants are sprayed on the bittercress and compound feed is added once, while they are grazed for 5 hours. This operation is performed daily to increase the amount of exercise and food intake of the geese for fattening.

[0045] Comparative Example 1: Select a shrub forest with a canopy density of 75-85% to establish an ecological goose breeding ground, build a goose house that can shelter from wind and rain in the ecological breeding ground, and take good insulation measures. The goose house has a movable door and a water trough outside the goose house. Solanum oleiferum is planted in the ecological breeding ground, and the ecological breeding ground is surrounded by a fence;

[0046] Establish an ecological breeding ground and set the stocking density at 10 / m 2 Ding'an geese aged 8-10 days were fed with compound feed three times a day. During the breeding process, an attractant (fennel powder and tangerine peel powder with a mass ratio of 1:1, diluted 7 times with water) was sprayed on the dandelions at 9:00-10:00 in the morning. After grazing for 3 hours, the geese were driven back to the goose house for hunger stimulation for 3 hours, corn feed was scattered around the ecological breeding ground, and they were grazed again for 4 hours.

[0047] Ding'an geese are released into the wild until they are 30-32 days old, and are fed with compound feed three times a day. At 9:00-10:00 a.m., an attractant (fennel powder and tangerine peel powder in a mass ratio of 1:1, diluted 7 times with water) is sprayed on the bittercress, and compound feed is added once, while grazing for 5 hours. This operation is performed daily to increase the geese's exercise and food intake for fattening.

[0048] The compound feed is composed of 80% corn feed and 20% silage. The preparation method of silage is as follows: banana stems and leaves and sugarcane stalks are crushed, and Lactobacillus plantarum culture solution (viable bacteria count 1×10 10 / g), stirred, put into bags, evacuated and sealed, and fermented at 28-30°C for 30 days to obtain silage; the components and amounts of silage are the same as those in Table 2.

[0049] Comparative Example 2: Select a shrub forest with a canopy density of 75-85% to establish an ecological goose breeding ground, build a goose house that can shelter from wind and rain in the ecological breeding ground, and take good insulation measures. The goose house has a movable door and a water trough outside the goose house. Solanum oleiferum is planted in the ecological breeding ground, and the ecological breeding ground is surrounded by a fence;

[0050] Establish an ecological breeding ground and set the stocking density at 10 / m 2 Dingan geese aged 8-10 days were fed corn feed three times a day. During the breeding process, attractants were sprayed on the dandelions and the geese were grazed for 4 hours.

[0051] Free-range Ding'an geese until they are 30-32 days old, feed corn three times a day; spray attractants on the bittercress, and feed corn once more, while grazing for 5 hours; perform this operation daily to increase the amount of exercise and food intake of the geese for fattening.

[0052] The growth performance and quality of the 120-day-old Ding'an geese obtained above were measured. The feed-to-meat ratio = body weight gain / feed consumption × 100. The CR-410 colorimeter was used to measure the brightness of the feathers on the back, left wing and abdomen of the geese. The L value in the colorimeter represents the brightness. The larger the L value, the whiter the feathers. The results are shown in Table 3.

[0053] Table 3 Feeding effect of each treatment group

[0054]

[0055] As can be seen from the above table, the present invention establishes an ecological breeding ground, adopts compound feed and attractant to match the stocking and fattening process, and constructs an ecological breeding method of dry-rearing geese. The survival rate of geese is above 98%, the feed-to-meat ratio is 2.10-2.13, the geese are in good development, healthy and energetic, and the size is relatively consistent when they are released. The ecological breeding method of dry-rearing helps to avoid water pollution, reduce fecal pollution and other problems, curb pollution sources, and stimulate goose digestion and absorption, and increase feed intake; from the perspective of feather brightness and integrity, the feathers of the geese raised in Examples 1 and 2 are bright and basically intact. The ecological breeding method of breeding geese constructed by the present invention effectively meets the feed intake of geese, promotes feather growth, and makes the feathers soft and fluffy. The compound feed is nutritionally balanced, the ecological environment is suitable, and the activities are sufficient, which avoids the geese pecking at each other and pecking feathers, improves the uniformity of feathers, and makes the feathers smooth and beautiful.

[0056] During the breeding process, if the daily temperature is higher than 37°C, a water trough can be temporarily placed under the gentle slope, and attractants can be added to the water trough to encourage the geese to drink more water. When the temperature is too high, placing the water trough too high will easily cause the geese to compete for food. Due to the gentle slope and the planting of pasture, this place is easily polluted.

[0057] According to the "Determination Method of pH Value, Organic Acid and Ammonia Nitrogen in Silage" DB15 / T 1458-2018, the prepared silage was quality tested, and the test results are shown in Table 4.

[0058] Table 4 Silage quality test results

[0059] pH Lactic acid / % Acetic acid / % Butyric acid / % Neutral detergent fiber / % Acid detergent fiber / % 3.96 4.62 5.25 0.31 26.3 11.5

[0060] As can be seen from Table 3, the silage prepared by the present invention using banana stems and leaves, sugarcane stalks and Aspergillus polydoctorius is of good quality, with high lactic acid and acetic acid contents and only 0.31% butyric acid; when Lactobacillus plantarum is used to replace Aspergillus polydoctorius, the lactic acid content of the silage prepared is improved, but the content of neutral detergent fiber and acid detergent fiber is high, which is easy to increase the digestive burden of geese on feed and reduce the absorption effect of silage.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
