Research results such as adjusting dietary calcium sources, calcium and phosphorus ratios, and supplementing vitamins have been widely used in production practice, but they have not achieved the expected results
[0004] Trace elements (such as zinc, manganese, copper) as a class of essential nutrients in the process of eggshell formation can act as cofactors for certain enzymes and regulate eggshell quality by affecting the formation of calcium carbonate and the crystal structure of eggshells. However, In the prior art, the eggshell quality is regulated by adjusting the dietary calcium source, the ratio of calcium to phosphorus, and supplementing vitamins. When used in production, it is found that the eggshell still has a certain breakage rate, mainly because calcium carbonate is only regulated through the metabolism of calcium ions. , ignoring the effect of the organic matrix, cannot effectively improve the quality of eggshells

Abstract
The invention discloses a feed capable of improving duck eggshell quality. The feed mainly consists of a basal feed and a premix in the mass ratio being 100 to (0.05-0.25), wherein the basal feed comprises the following raw materials in percentage by weight of 50-65% of corn, 10-30% of soybean meal, 5-10% of wheat bran, 5-10% of stone powder, 1-2% of calciumhydrogenphosphate, 0.1-0.5% of table salt, 0.1-0.2% of methionine and 0.01-0.02% of lysine; and the premix comprises the following trace elements of zinc, manganese, copper, iron, selenium, iodine and cobalt. Every kilogram of the basal feed comprises 20-100mg of the zinc, 20-100mg of the manganese, 2-10mg of the copper, 17-90mg of the iron, 0.10-0.50mg of the selenium, 0.10-0.50mg of the iodine and 0.06-0.3mg of the cobalt. The components and the content of the trace element premix in a feed for laying ducks are adjusted and controlled, so that formation of substrate proteins and proteoglycan in eggshells can be adjusted and controlled, the formation and the ultrastructure of eggshell crystals are adjusted and controlled, and the eggshell quality can be improved.
Description
technical field [0001] The invention relates to the technical field of poultry feed, in particular to a feed for improving the quality of duck egg shells. Background technique [0002] Eggshell quality is an important economic and appearance trait of duck eggs. With the increasing pressure of environmental protection and the transformation and upgrading of the waterfowl industry, the breeding method of laying ducks has gradually changed from free-range and peaceful breeding to large-scale and intensive cage breeding. The nutrients formed by egg shells are only provided by feed, coupled with the improvement of egg production performance. , The quality of eggshells is lower than that in the traditional breeding mode, and the mechanized operations in the intensive cage farming mode increase, and the quality of eggshells is particularly prominent in actual production. Compared with chicken eggs, duck eggs are mostly used for processing into egg products such as salted eggs or p...
