Qingnong Grey Goose Supporting System

Qingnong Grey Goose is a combination of traditional animal breeding methods and modern biotechnology. Professor Wang Baowei of Qingdao Agricultural University adopts the principle of homogenous matching. Through blocking and pedigree breeding, the genes of good traits are continuously homogenized and fixed. The two green farm grey geese supporting systems mainly for producing liver and producing meat are suitable for the production of fatty liver goose and meat goose.

The fertilization rate of hatching eggs and the hatching rate of fertilized eggs reached over 91% in the production performance of Qingnong grey foie gras type and meat-type matching eggs, and the hatching rate of hatching eggs was over 85%, and the hatching rate was over 94%.

The average initial weight of green goose type liver goose type grey goose is 108.2 grams, the average survival rate is 06.1 weeks from 0 to 10 weeks, the average weight is about 5.1 kilograms at 10 weeks, and the average feed conversion rate at 10 weeks is about 2.24. 1:1; 10-week-old slaughter rate of 90%, half-netting rate of 82%, the total net skeleton rate of 73%, leg muscle rate of 16%, chest muscle rate of 13%, abdominal fat rate of 4.5%. When feeding, the average liver weight was about 1.1 kg, and the feed liver ratio was 22.9:1.

The average birth weight of grey goose for meat type commercial products for Qingnong grey goose is 106.2 grams, the average survival rate is 06.1 weeks from 0 to 10 weeks, the average weight is about 5.1 kilograms at 10 weeks, and the average feed conversion rate at 10 weeks is about 2.24. 1:1.10-week-old slaughter rate of 89%, semi-net licking rate of 80%, full net licking rate of 71%, leg muscle rate of 11%, chest muscle rate of 11%, abdominal fat rate of 4.5%.
