| Zusammenfassung: | The invention relates to a secondary laying starting method for non-laying broiler breeders, which comprises the following steps: shading, cutting off water and stopping feeding for the non-laying broiler breeders, and starting feeding when the non-laying broiler breeders meet the following conditions: the weight loss ratio meets the weight loss requirement, and the weight of abdominal fat is lower than 30g; or the daily weight loss is 30 +/-5g, and the weight of abdominal fat is less than 30g. According to the method, stress is artificially given to the non-laying broiler breeders, the non-laying broiler breeders are insufficient in nutrition supply and disordered in metabolism, the reproductive system of the non-laying broiler breeders is atrophic, and the reproductive capacity of the non-laying broiler breeders is lost, and then conditions meeting the physiological needs of the broiler breeders are artificially given, so that the reproductive performance of the non-laying broiler breeders is secondarily de |
