However, by restricting energy intake, it is impossible to ensure that the energy intake level meets the minimum requirement, and if the energy level of the diet is too low, the feed intake of laying ducks will increase, thereby increasing the consumption of feed, resulting in food cost increase

Embodiment 1
[0029] A limited feed ration for laying ducks in the breeding period, comprising the following raw materials in weight percentage: 47% of corn, 6% of soybean meal, 5% of rapeseed meal, 17.3% of secondary meal, 8% of wheat bran, fermented alfalfa powder 3%, edible mushroom chaff 5%, bentonite 4%, stone powder 2% and premix 2.7%.
[0030] Based on 1 ton of the restricted ration, the premix includes the following components: 2-5kg lysine, 1-2.5kg methionine, 8-11kg calcium hydrogen phosphate, 2-3kg salt, VA 12 -15g, VB 1 1-2 g, VB 2 5-15 g, VB 6 2-4 g, VD 3 2-4g, VE8-12g, VK 3 0.5-0.8g, biotin 0.1-0.2g, folic acid 0.1-0.2g, D-pantothenic acid 40-60g, niacin 40-60g, choline 500-800g, ethoxyquinoline 100-120g, copper sulfate pentahydrate 24-32g, ferrous sulfate heptahydrate 200-300g, manganese sulfate monohydrate 150-250g, zinc sulfate heptahydrate 180-300g, potassium iodide 0.3-0.6g, sodium selenite 0.22-0.44g, sepiolite 7-10kg .

Abstract
The invention provides limited feeding grain for laying ducks in a breeding period and a preparation method of the limited feeding grain. The limited feeding grain comprises the following raw materials in percentage by weight: 35%-50% of corn, 3%-6% of soybean meal, 4%-5% of rapeseed meal, 10%-20% of wheat middling, 8%-10% of wheat bran, 3%-5% of fermented alfalfa meal, 4%-6% of edible fungus bran, 4%-10% of bentonite, 2%-4% of stone powder and 2%-4% of a premix. The preparation method comprises the following steps: step 1, obtaining a raw material mixture with a grain size of 1.5-2.0 mm; step2, heating the raw material mixture to 80-85 DEG C and keeping the raw material mixture at the constant temperature for 25-50 s to prepare a cooked raw material mixture; and step 3, preparing granular limited feeding grain from the cooked raw material mixture by a granulator. The limited feeding grain is low in cost, the egg laying peak rises fast and high and lasts for a long time, and the preparation method is easy in parameter control and high in practicability.
Description
technical field [0001] The invention relates to the technical field of feeding methods for laying ducks, in particular to a limited-feeding ration for laying ducks in the breeding period and a preparation method thereof. Background technique [0002] With the rise of the off-water farming model, the traditional farming model of laying ducks has gradually been replaced. In the intensive out-of-water aquaculture mode, laying ducks can leave the water surface, and the rations used to feed laying ducks are mostly corn or rice with single nutrition. Although this can save the feeding cost of laying ducks in the breeding period, it cannot meet the requirements The growth and development needs of ducks make the body maturation of laying ducks slower, and it is difficult to ensure that the body maturity of laying ducks is consistent with sexual maturity. Therefore, in order to ensure that the body maturity and sexual maturity of laying ducks tend to be consistent, the rearing techn...
