Novel method for feeding egg newborn chick with high efficiency

Abstract

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.

Description

technical field [0001] The invention belongs to the animal husbandry technology in the field of agriculture, and in particular relates to a new method for efficiently raising chicks. The method measures the feeding effect of chicks by using body shape indicators. Background technique [0002] Modern studies have shown that the basis for determining the production performance of laying hens mainly depends on the development of body shape during the growth period. The body shape of a chicken refers to the general term of the skeleton, muscles, viscera, feathers and other substances in the body. It is often measured by the "double index" of weight and shin length (which is strongly correlated with the development of the chicken body skeleton). Especially in the brooding stage of laying hens (0-8 weeks old), the weight gain of the chicken accounts for about 27% of the adult body weight, while the growth of the shin length is 75%-80% of the adult, and the development of the two i...

Problems solved by technology

How to change the conventional feeding and management methods of layer chicks so that the body shape of the chickens can be optimally developed is a realistic technical problem in current production, and there is no practical research report on this aspect in China
