Laying duck feed and preparation method thereof

Abstract

The invention discloses laying duck feed, which is characterized by being prepared from the following ingredients in parts by weight: 45 to 55 parts of corn slag, 20 to 25 parts of bean meal, 10 to 15parts of rice bran, 5 to 10 parts of shell powder, 2 to 5 parts of composite vitamin, 2 to 5 parts of allicin, 1 to 4 parts of table salt and 10 to 15 parts of fructus crataegi cuneatae. The laying ducks can obtain sufficient nutrition; the growth performance and immunity of the laying ducks can be improved; the effects of preventing diseases and treating diseases can be achieved; the growth anddevelopment of the laying ducks can be promoted. Through fructus crataegi cuneatae and allicin, the effects of benefiting the spleen, strengthening the stomach, regulating qi, helping digestion, promoting digestive absorption, enhancing metabolism and immunity and the like can be achieved; the intestinal mucosa adsorption function can be improved; the problems of inappetence, dyspepsia, low feed utilization rate, disease resistant reduction, slow growth, low egg yield or even death and the like can be effectively solved, so that the growth performance of the laying ducks can be improved. In addition, trace elements such as composite vitamin are added into the composite vitamin; the nutrition in the feed is more comprehensive; the feed is more suitable for laying ducks; the health and fastgrowth of the laying ducks can be promoted.

Description

technical field [0001] The invention relates to a feed for laying ducks and a preparation method thereof, belonging to the technical field of feed production. Background technique [0002] At present, domestic and foreign studies on the nutrition of ducks mainly focus on meat ducks, and studies on the nutritional requirements mainly focus on protein, but there are few studies on the nutrition of laying ducks, and even less research on the amino acid requirements of laying ducks. [0003] The final peak period of laying ducks from brooding to absolute weight gain is about 50 days at the age of 7 weeks, and then gradually declines. Some egg-type duck feeds are not designed according to the growth stage and weight gain characteristics of egg-type ducks and the development trend of the body. The nutrients are not enough to meet the nutritional needs of egg-type ducks at different growth stages, which affects the quality of egg-type ducks. Growth and development, resulting in a ...

AI Technical Summary

Problems solved by technology

Some egg-type duck feeds are not designed according to the growth stage and weight gain characteristics of egg-type ducks and the development trend of the body. The nutrients are not enough to meet the nutritional needs of egg-type ducks at different growth stages, which affects the quality of egg-type ducks. Growth and development, resulting in a decrease in egg production, suppression of immune function, decline in causative power, and the occurrence of certain poultry diseases, which increase the cost of treatment for poultry diseases; some feeds contain excessive nutrients that exceed the body's needs, resulting in excessive waste and increased breeding costs. Costs, Reduced Margins, and Economic Benefits

Moreover, some feeds are not conducive to the development of duck breeding production due to their complex chemical composition, high cost, and unclear side effects.
