Problems solved by technology

There are three disadvantages in this kind of feed preparation: first, there is no special feed to improve gizzard motility and liver cell membrane fluidity in the traditional pre-feeding period; Feed preparation during feeding period The process of mixing corn, oil and premix in a container will cause uneven mixing of oil and premix and partial waste
In addition, the traditional filling formula is composed mainly of starch raw materials and a small amount of protein raw materials are added, but through the research on the production mechanism of fatty liver, it is found that protein may affect the transport of lipids by supplying lipoprotein synthesis, Davail et al. (Davail S , Guy G, Andre J M, et O 1. Metabolism in two breeds of geese with moderate or large overfeeding induced liver-steatosis[Jl Comp Biochem Physiol A, 2000,126:91-99) reported part of the newly formed triglyceride (Triglyceride , TG) will be combined with very low density lipoprotein (VLDL) in the liver and secreted into the blood, so reducing the protein source in the formula may reduce the synthesis of VLDL and thus reduce the synthesis of VLDL in the liver TG is transported into the blood
In addition, the traditional method of feed preparation technology uses boiling water to cook corn for the purpose of gelatinizing the starch in the corn and improving the utilization efficiency of starch. However, because the boiling time is too short, the starch gelatinization degree of most corn is only 30- 40%, and the water content after cooking is very high, the dry matter is relatively reduced, and the utilization efficiency of feed is greatly reduced

Embodiment 1

[0023] In the present invention, 90 mule drakes of the same 12-week age are respectively selected, pre-fed from 10-week-old, and fed from 12-week-old, and divided into a control group and a treatment group.

[0024] The control group feed was based on the traditional formula of corn + oil + premix, and the production method followed the traditional method of boiling in boiling water for 5-10 minutes, draining, mixing oil, and mixing the premix well.

[0025] The feed of the treatment group adopts the formula of the present invention, 70 g of corn is pulverized, passed through a 20-mesh sieve, the conditioning temperature is 70 ℃ ~ 80 ℃, the conditioning time is 40 ~ 60 seconds, the compression ratio of the ring die (referring to the effective working length of the ring die and the die hole) The ratio of diameters) is 1:4. After mixing and granulating, the post-curing process (a process of fully curing the feed by placing or heating) is used for heating, and the post-curing temp...

[0039] Same as Example 1, divided into control group and treatment group, the treatment mode of the control group is the same as that of Example 1; the preparation method of the feed in the treatment group is the same as that of Example 1, the difference is that each component formula and premix in the feed Select conventional commercially available products, as follows:

[0040] The dosage of each raw material component of the feed during the pre-feeding period is:

[0041] Corn: 60.0g, soybean meal: 10.0g, rapeseed meal: 5.0g, rice bran meal: 12.0g, palm meal: 3.8g, salt: 0.36g, calcium hydrogen phosphate 1.2g, calcium carbonate: 1.4g, soybean lecithin powder : 3.0g, 65% lysine sulfate: 1.3g, methionine: 0.3g, premix (Wuhan Huisen Technology Co., Ltd.): 1.2g, compound enzyme preparation (Beijing Youlibao Biotechnology Co., Ltd.): 0.33g, antioxidant: 0.05g, calcium propionate 0.06g;

Abstract

The invention relates to a novel duck feed for the production of duck fat liver, fat liver production is divided into a pre feeding period and an overfeeding period for formula design of the duck feed, a low energy high fiber pre feeding feed is used in the pre feeding period, and comprises corn, soybean meal, rapeseed meal, rice bran meal, palm meal, salt, calcium hydrophosphate, calcium carbonate, soy lecithin powder, lysine sulfate, methionine, a premix, a compound enzyme, a preservative and an antioxidant; a high energy low protein overfeeding feed is used in the overfeeding period, and comprises the corn, corn starch, the salt, the calcium hydrophosphate, the calcium carbonate, baking soda, the soy lecithin powder, soybean oil, the premix, the preservative, the compound enzyme and the antioxidant, and the novel duck feed substantially improves the duck fat liver weight and quality, and improves the liver production efficiency.

Description

technical field [0001] The invention relates to a poultry feed, in particular to a duck feed used for producing duck fat liver. Background technique [0002] Fatty liver is not only favored by high-end consumers because of its delicious taste, but also rich in nutrients, containing a large amount of essential fatty acids and lecithin required by the human body. In recent years, the global output of duck fat liver has reached more than 18,000 tons, which is more than 6 times that of goose fat liver. In the production of duck fat liver, feed plays a decisive role in the weight and quality of fat liver, and accounts for 70% of the production cost. It is necessary to develop a compound feed that can reduce production cost, improve fatty liver quality and improve liver production efficiency. [0003] The traditional fat liver production does not consider the feed formula for the pre-feeding period of fat liver production, and often uses general compound feed plus pasture to fee...
