Production process of spf chicken

Abstract

The production process of the SPF chicken relates to the field of poultry feeding, and solves the problems of the existing SPF chicken production methods, such as low hatching rate and low egg production performance, and inability to better adapt to the environment. The process is as follows: eggs are hatched after being sterilized, 48 hours before hatching, the SPF chicken barrier system is fumigated with formalin and potassium permanganate for 24 hours, the hatching period is 18 days at sunset, and until the 21st day, the chicks are hatched within 48 hours. Start to feed the high-pressure sterilized SPF chicken brooding period feed. The chicks are raised to 42 days old and moved to the breeding chicken breeding room. After the chicks are raised to 18 weeks old, they become adult chickens. When the chicks are raised to 17 weeks old, they will be transferred to the group. SPF adult chicken feed is formulated with complete rations according to the nutritional needs of chickens. The present invention controls and adjusts the most suitable temperature and humidity by hatching parameters and appropriately increases the damper, so that the hatching rate can reach 98%, the 17-week-old mixed flock can ensure a fertilization rate of more than 96%, and the adapted lighting program can improve the peak egg production performance of chicken flocks. Increase to 88% for 2 weeks, and the egg production rate above 80% can last for 12 weeks.

Description

technical field [0001] The invention relates to the technical field of poultry feeding, in particular to a production process of SPF chickens. Background technique [0002] SPF (Specificpathogen Free, SPF) animals refer to animals without specific microorganisms and parasites in the body. SPF chickens refer to chickens that are raised in barrier systems or isolators, without the pathogens of major chicken infectious diseases that are popular internationally and domestically (especially domestically), and do not contain corresponding antibodies, and have stable genetic characteristics and production performance. The eggs produced by SPF chickens are SPF eggs. Because they do not carry specific pathogens, SPF chicken embryos have been widely used in various fields of virology research and biopharmaceuticals. [0003] The microbiological control of SPF chickens is mainly formulated by various countries and even some production units based on international and domestic actualit...
