Preparation method of feed for laying ducks

Abstract

A preparation method of feed for laying ducks includes the following steps: medicated leaven, pericarpium citri reticulatae, asparagus cochinchinensis, radix puerariae, fructus crataegi and medical stone powder are subjected to superfine grinding and then soaked in water, the soaked mixture is decocted, the decoction is filtered, and the obtained filtrate is concentrated by 8 to 9 times to obtain a concentrated solution; corns, bean pulp, citric acid scrap, rice bran, meat powder and fish powder are uniformly mixed, and the mixture is subjected to superfine grinding to obtain a mixture A; the concentrated solution is added into the mixture A; after stirring evenly, temperature preservation is performed at the temperature of 80-85 DEG C for 40 minutes, alum powder is added, temperature preservation is performed at the temperature of 50-60 DEG C for 1 to 2 hours, and the mixture is cooled to the room temperature after the temperature preservation to obtain a mixture B; calcined oyster shell powder is added into the mixture B, and vitamin complexes and compound minerals are then added into the mixture B after temperature preservation to be made into granulated feed, namely the feed for laying ducks. The feed prepared according to the invention can provide sufficient nutrients for laying ducks, so as to improve the growth performance, egg yield and immunity of laying ducks.

Description

technical field [0001] The invention relates to a feed, in particular to a method for preparing duck feed for eggs. Background technique [0002] The final peak period of egg-type 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 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 margin...

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.
