The invention discloses a method for feeding an egg newborn chick with high efficiency in the field of agricultural pasturage breeding. The method takes a mode that body type indexes reach the standard as a standard and finds out the body type indexes that the determining degree of the brooding period of layers to the laying performance is maximum. The breeding process comprises the following steps: a preventive medicine of one treatment course is added in the feed of 3-5 days before 20 ages in days in the 7-11 ages in days of a newborn chick; within 1-2 days before and after immunization of each time, a stress-resisting additive is added into the drinking water of the newborn chick; the nutritional level of rations of 0-3 ages in week or 0-4 ages in week is higher than that of rations atthe later period of brooding; the newborn chick is fed with a feed to 8 ages in week; and after 8 weeks, the feed is replaced by rations for raising grown chickens. Compared with a conventional breeding method, the method enhances the standard reaching rates of the body weight and the shank length of the newborn chick with 8 ages in week by 12.4% and 9.3% respectively, enhances the uniformity of chick colonies by 8.4%, enhances the egg yield by 7.2%, lowers the mortality rate of the laying period by 4.3% and enhances the benefit of breeding chickens by 18.7%; and the input-output ratio averagely reaches 1:8.1.
