Embodiment 1

[0017] Embodiment 1 improves the method for taurine content in eggs

[0018] In this example, laying hens were selected for the test during the peak egg production period, and cystine was added to the diet with a cystine level of 0.26% in the basal diet (see Table 1 and Table 2 for the formula and part of the nutrient content, respectively). and vitamin B 6 mixture, so that the dietary cystine content reached 0.31%, 0.46%, 0.62%, 0.93%, vitamin B 6 The content reaches 0.002%. The experiment was carried out for 8 weeks.

[0019] Table 1 Basic diet formula

[0020]

[0021] Note: Add artificially synthesized cystine and vitamin B to the basal diet 6 After that, reduce the amount of medical stone accordingly, so that the total amount of each raw material reaches 100%. Raw materials such as corn and soybean meal in the basic diet contain a small amount of cystine, and the multivitamins contain vitamin B 6 .

Abstract

The invention provides a method for increasing content of taurine in poultry eggs, which is realized through directly adding artificially synthesized cystine in daily ration of laying fowls to reach the extent that the content of cystine in the feed is 2-4 times of the required amount and the content of vitamin B6 is 2-5 times of the required amount. According to the method, the cystine in daily ration can be used for synthesizing the taurine in animals, the content of taurine in yolks is improved greatly, and is 5 times of the content of taurine in common yolks of poultry eggs to the hilt.

Description

technical field [0001] The invention belongs to the field of feed for eggs and poultry, and in particular relates to a method for increasing the content of taurine in poultry eggs. Background technique [0002] Taurine, whose chemical name is 2-aminoethanesulfonic acid, is one of the family of free amino acids and sulfur-containing amino acids with the highest content in animals. At present, it has been confirmed that it has important functions such as preventing cardiovascular diseases, enhancing human body constitution, promoting brain tissue and intellectual development of infants, and improving nerve conduction and visual functions. [0003] Studies have shown that plant foods contain almost no taurine, the content of taurine in milk and eggs is not high, and the taurine in eggs is mainly concentrated in the yolk. Taurine mainly exists in marine fish, reaching 3562mg / kg dry weight. At present, taurine is mainly synthesized by chemicals, and has been widely used in dair...
