Method for releasing on-day-age ducks in rice-duck integrated farming

Abstract

The invention relates to agriculture breeding and a planting technology, in particular to a method for releasing on-day-age ducks in rice-duck integrated farming. The method for releasing the on-day-age ducks in the rice-duck integrated farming comprises the steps: (a) selecting hatching time of newly-hatched ducklings, wherein 23-25 days after local rice planting time are confirmed as duck egg hatching time, and ducks are existing shelducks or working ducks; (b) selecting duck releasing time, wherein on-day-age ducklings are directly placed into a rice field where rice are planted for 3-5 days after feather dries; and (c) setting environment requirements, wherein the depth of a rice field water layer is 3-5cm, and 12-20 ducks are bred in each mu of rice field. By means of the method, prejudice on a traditional duck breeding theory is broken out, the processes of heat preservation brooding of household ducks in the rice-duck integrated farming and in-advance domesticating in water are omitted, the method is simple and easy to operate, the constitution of the ducklings can be improved obviously, and survival rate of the ducklings can be improved to 95-100%.

Description

technical field [0001] The invention relates to agricultural breeding and planting technology, in particular to a day-old duck releasing method in rice-duck co-production. Background technique [0002] The traditional domestic duck breeding theory believes that ducklings are weak in cold protection and need to be warmed in the early stage of brooding. It is generally believed that the temperature requirements for duck brooding are: 1 day old 28-26°C, 2-7 days old 26-22°C, 8-14 days old 22-18°C, 15-21 days old 18-16°C. Ducklings should start from the age of 6 days. [0003] In the current rice-duck co-production, based on the duck raising theory above, the ducklings are usually put into the rice field after heat preservation and brooding, and the water is tamed in advance. The ducklings for ducks are 7-14 days old. It is more difficult for rice farmers, and the operation technology is difficult, which makes the ducklings weak and affects the survival rate after the ducks ar...
