Problems solved by technology

[0003] At present, the quality of duck egg products is not high, high-quality egg products are scarce, and the market competitiveness is weak. Egg products are affected by the quality of feed materials, and the taste is poor. Multifunctional products, especially polyunsaturated fatty acid enriched products, only consider the amount of content, not Consider the ratio of n-6 / n-3 and the absorption and utilization of the human body

Embodiment 1

[0026] 1. Test materials and methods:

[0027] 960 ducks from the peak egg laying period with healthy, normal feed intake and close weight were randomly divided into 4 groups: control group 1, control group 2, experimental group 1, and experimental group 2, with 8 replicates in each group. 30 birds per repetition. The corn-soybean meal type basic feed was used, the experimental group was fed the experimental group feed, and the control group was fed the control group feed. The test ducks were fed regularly, drinking water freely, while maintaining the environmental hygiene of the duck house, with 17 hours of light per day (intensity not less than 15 lux / m2) 2 ). The trial period was 12 weeks. Fifty-four eggs were collected from each replicate for sample testing, of which 4 eggs were tested for fatty acid content in egg yolks, and the remaining 50 eggs were salted for 60 days, and 10 eggs were selected from each replicate for sensory scoring.

Abstract

The invention discloses a feed for producing duck eggs rich in polyunsaturated fatty acids beneficial to human health and a preparation method of the feed. Belongs to the technical field of feed. Each kilogram of the feed comprises 262.1 to 295.6 g of corn, 116.5 to 118.2 g of wheat, 263 to 284.2 g of wheat bran, 168.3 to 178.9 g of soybean meal, 5 to 25 g of flaxseeds, 18 to 22 g of soybean oil, 11 to 11.5 g of calcium hydrophosphate, 85 to 95 g of stone powder, 1.5 to 1.9 g of DL-methionine, 2.5 to 3 g of salt, 0.7 to 0.9 g of arginine, 1.4 to 1.5 g of lysine hydrochloride, 0.18 to 0.22 g of tryptophan, 0 to 0.1 g of threonine, 0.5 to 0.6 g of compound enzyme, 3 to 4 g of binding elements and 10 g of premix. The method is used for producing duck egg products which are good in taste and have polyunsaturated fatty acid with the proportion suitable for human body absorption, and technical support is provided for multifunctional food production.

Description

technical field [0001] The invention relates to the technical field of feed, and more particularly to a feed for producing duck eggs rich in polyunsaturated fatty acids beneficial to human health and a preparation method thereof. Background technique [0002] Functional polyunsaturated fatty acids have become a research hotspot due to their superior physiological effects. A reasonable proportion of polyunsaturated fatty acids in the diet can effectively maintain physical health, promote growth and development, reduce the incidence of cardiovascular and cerebrovascular diseases, and reduce blood lipids and blood pressure. According to WHO and FAO, the ratio of n-6 / n-3 in food is 5-10:1, which is the optimal range for human health intake of polyunsaturated fatty acids, which is easier for human body to absorb and utilize. [0003] At present, the quality of duck egg products is not high, high-quality egg products are scarce, and market competitiveness is weak. Egg products are...
