Laying duck feed for enriching calcium and preventing diseases and production method thereof

Abstract

The invention discloses a laying duck feed for enriching calcium and preventing diseases and a production method thereof. The feed comprises the following raw materials in parts by weight: 100-150 parts of soybean meal, 70-100 parts of distillers' grains of corn, 50-80 parts of vegetable dregs, 30-50 parts of hay powder, 20-30 parts of peanut shell flour, 15-20 parts of tea leaf residues, 15-20 parts of fruit peels, 0.3-0.5 part of a fermentation agent, 50-70 parts of shrimp bran, 20-30 parts of particles of hoofs and horns, 20-30 parts of pig bone powder, 5-10 parts of turtle oil, 2-3 parts of cuttlefish oil, 40-50 parts of fresh corn leaves, 30-40 parts of Chinese cabbage leaves, 3-4 parts of folium isatidis, 2-3 parts of stringy stonecrop herbs, 1-2 parts of wild chrysanthemums, 2-3 parts of radix scutellariae, 2-3 parts of costus roots and 5-15 parts of an insect repellent. The feed disclosed by the invention can provide a sufficient number of superior calcium sources for laying ducks, so that the intensity and the smoothness of eggshells are enhanced, and the eggshells are hard and are not easy to damage. The feed disclosed by the invention can also increase the egg laying rate of the laying ducks, improves the quality of duck eggs, enhances the physique of the laying ducks and reduces the occurrence of diseases and pestilence.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a feed for calcium supplementation and disease prevention for laying ducks and a preparation method thereof. Background technique [0002] The nutritional needs of captive laying ducks are completely supplied by commercial full-price feed. To maintain the egg production rate of captive laying ducks and increase the commercial rate of eggs, in addition to meeting the needs of protein and energy nutrition, special attention must be paid to calcium supplementation. A duck eggshell contains 2.9-3.02 grams of calcium, and the utilization rate of calcium for laying ducks is about 65%. Therefore, 4.8-5.12 grams of calcium is needed to produce an egg. Reasonable calcium supplementation can reduce the breakage rate of duck eggs. If the calcium in the feed is insufficient, the laying duck will use the calcium in the bones to form eggshells. The longer the calcium in the bones is u...

AI Technical Summary

Problems solved by technology

If the calcium in the feed is insufficient, the laying duck will use the calcium in the bones to form eggshells. The longer the calcium in the bones is used to form eggshells, the weaker the eggshell strength will be, and even soft-shell eggs or shellless eggs will appear. This not only leads to a decline in the egg production rate of laying ducks, but also seriously affects the quality of duck eggs
