Problems solved by technology

[0002] Duck meat is delicious and nutritious. With the increase of people’s demand for meat ducks, the stock of meat ducks is gradually increasing. Feed raw materials are limited, which cannot meet the feed demand of meat ducks. With the improvement of people’s health awareness, the reduction of meat The sebum rate of ducks has become the main standard, and the existing methods to reduce the sebum rate are mainly to reduce the fatness of meat ducks by feeding high-protein, low-energy feed, adjusting the amino acid content in the feed, or adopting moderate feeding restrictions. However, due to the vigorous development of the breeding industry, the source of main feed raw materials is limited, which affects the price of feed. Therefore, further research on meat duck feed is needed to improve the quality of meat duck while controlling feed costs.

Embodiment 1

[0011] A breeding method for reducing the sebum precipitation of meat ducks. A playground is set near the duck house. During the middle duck period, the exercise time in the playground is 4.5 hours every day. Drinking water is prepared in the playground, and the middle duck feed is fed 4 times a day. Duck feed is made of the following raw materials in parts by weight: 68 parts of corn flour, 30 parts of dry sweet potato powder, 12 parts of bran, 10 parts of rapeseed meal, 8 parts of soybean meal, 5 parts of rye flour, 4 parts of corn gluten powder, shell powder 2 parts, 0.4 parts of salt, 4.2 parts of calcium carbonate, 4 parts of green onion powder, 5.8 parts of sunflower petal fried dry powder, 4 parts of premix; during the adult duck period, the sports time is 7.5 hours a day in the sports field, and there is enough drinking water in the sports field. The duck feed was fed 5 times a day, and the duck feed was made of the following raw materials in parts by weight: 58 parts o...

The duck feed is made of the following raw materials in parts by weight: 70 parts of corn flour, 28 parts of sweet potato dry powder, 15 parts of bran, 8 parts of rapeseed meal, 6 parts of soybean meal, 6 parts of rye flour, 3 parts of corn gluten powder, shell powder 3 parts, 0.5 parts of salt, 4.7 parts of calcium carbonate, 6 parts of green onion powder, 4.5 parts of sunflower petal fried dry powder, 5 parts of premix; during the adult duck period, the sports time is 8 hours a day in the sports field, and there is enough drinking water in the sports field. The duck feed was fed 5 times a day, and the duck feed was made of the following raw materials in parts by weight: 55 p...

Embodiment 3

[0017] A breeding method for reducing the sebum precipitation of meat ducks. A playground is set near the duck house. During the middle duck period, the exercise time in the playground is 5 hours a day, and sufficient drinking water is prepared in the playground, and the middle duck feed is fed 4 times a day. Duck feed is made of the following raw materials in parts by weight: 65 parts of corn flour, 34 parts of dry sweet potato powder, 8 parts of bran, 12 parts of rapeseed meal, 10 parts of soybean meal, 4 parts of rye flour, 6 parts of corn gluten powder, shell powder 1 part, 0.3 parts of salt, 3.8 parts of calcium carbonate, 3 parts of green onion powder, 7.5 parts of sunflower petal fried dry powder, 3 parts of premix; during the adult duck period, the sports time is 7 hours a day in the sports field, and there is enough drinking water in the sports field. Duck feed was fed 5 times a day, and the feed for ducks was made of the following raw materials in parts by weight: 60 ...

Abstract

The invention belongs to the technical field of duck breeding, and particularly relates to a breeding method capable of lowering duck's sebum deposition. The breeding method includes that a movement field is set up around a duck house, movement time of ducks in the movement field is 4-5h each day at the medium-duck stage, sufficient drinking water is prepared in the movement field, and medium-duckfeed is fed for four times each day; movement time of the ducks in the movement field is 7-8h each day at the adult-duck stage, adult-duck feed is fed for five times each day, and the drinking watercontains palm kernel oil. Compared with the prior art, the breeding method has the advantages that according to growing characteristics of the ducks at each stage, dried sweet potato powder is utilized to replace part of energy feed; a proper amount of fried sunflower petal powder is utilized to cooperate with onion powder, so that feed intake of the ducks can be increased, and gastrointestinal discomfort caused by excessive adding of sweet potato is avoided; proper movement and water drinking are combined, so that disease resistance of the ducks can be improved, and feed-meat ratio can be lowered; abdominal fat percentage of the ducks can be lowered by 10% when compared with that of existing feed, and the breeding method is simple in management and easy to popularize and use.
