Breeding method for hatching eggs of swan geese

Abstract

The invention relates to a breeding method for hatching eggs of swan geese, and relates to technical field of cultivation. The method is characterized by comprising following steps of: a, a breeding preparation period: one month before swan geese lay eggs is the breeding preparation period, preparations are made for egg laying, a concentrated supplement is taken as a main feed supplement, male and female geese are bred separately, the male geese are fed with the supplement 3 times everyday, and the female geese are fed 2 times everyday; b, a breeding period: the breeding period mainly adopts goose house breeding and is supplemented by grazing, the geese are fed 2-3 times everyday, one more feeding is added at nights, adequate mineral feeds are supplemented, and enough water is placed; and c, a no-laying period: the female geese lay egg until July, laid eggs are reduced, feathers are dry, sexual desires of the male geese decreased, the no-laying period starts, the concentrated supplement is changed into a coarse supplement, the period is changed into a coarse feeding period with priority to grazing, whole day grazing can be achieved, supplements are not fed, supplements are fed appropriately in poor grazing conditions or successive rainy days, and feeding is kept in winter by adding 20-30% of maize flour into cabbages, maize straw powder and grass powder to keep the weight of the geese from decrease. The breeding method is scientific, the egg laying rate and the fertilization rate of the female geese are high, the number of laid eggs is large, the breeding cost is low, and the economic benefit is good.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a method for raising gray swan breeding geese.
