Yangzhou Goose was selected from Yangzhou University and Yangzhou Agriculture and Forestry Bureau as the female parent. It has been approved by the Jiangsu Provincial Livestock and Poultry Variety Approval Committee.

Yangzhou Goose is a medium-sized goose breed with genetic stability, high reproduction rate, early growth, excellent meat quality, resistance to rough feeding, strong adaptability, high feed conversion rate of young geese, and delicate meat quality. According to the data from the National Poultry Production Performance Test Station, the average weight of meat geese at 70 days is 3.52 kg under house-feeding conditions; the average body weight is 4.05 kg under grazing and supplementation; the feed-to-meat ratio is 2.69:1; the goose slaughter rate is 89.4%, the slaughter rate of female goose was 85.9%; the number of laying geese at the age of 65 weeks was 71, the average egg weight was 139.5 grams, the fertilization rate of eggs was 92%, and the hatching rate was 88.5%.

Breeding technology points: 1 feeding methods. The combination of grazing and supplementation is more economical. Grazing once a day in the morning and afternoon, supplementing appropriate amount of compound feed or cereal feed, and supplementing green feed at night. Grazing should be avoided thunderstorms, heat, summer early morning early return, afternoon late evening return, pasture requirements grass tender, no pollution, water should be clean, prevent wild animals infestation. 2 stocking density. Feeding volume per square meter, 20 to 25 at 1 to 5 days, 15 to 20 at 6 to 10 days, 12 to 15 at 11 to 15 days, 8 to 12 at 16 to 20 days, after 20 days The density is gradually reduced, and it should be grouped according to the size and strength of the goslings and reared in groups.

The breeding Yangzhou Goose has the following advantages: First, the Yangzhou goose concentrates the advantages of the male parent and the female parent. It has a fast growing speed, a good meat quality, and a high reproductive rate. In general, a 70-day-old goose can reach 3.3-3.5 kilograms. Taihu geese grow at a high rate of 27.8%. Followed by the good meat quality of the offspring, meat protein content is 1% higher than its father. The third is that the egg production level is relatively high, the annual egg production can reach 72 to 75, and 62 to 64 goslings can be produced. It is also resistant to rough feeding, and it can be eaten by many kinds of grass when grazing.

Additives mainly refer to various antibiotics, antioxidants, mold inhibitors, binders, colorants, flavouring agents, health care and metabolic regulation drugs, etc. are conducive to enhancing feeding effect, conducive to the production and storage of non-nutritive Feed Additives and their formulated products. It is mainly divided into food additives, feed additives, concrete additives, and oil additives.

Food additives refer to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are a term that refers to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are generally not food and may not have nutritional value, but they must conform to the above definition, that is, they do not affect the nutritional value of food, and can prevent food spoilage, enhance food sensory properties or improve food quality.

Feed additives, also known as feed additives, refer to the general term of additives manually added to formula feed in order to make up for the shortcomings of formula feed and some special needs. The functions of additives include: 1) insufficient nutrients in feed; 2) preventing deterioration of feed quality; 3) improving palatability of feed and utilization rate of feed; 4) enhancing disease resistance of feeding animals, promoting normal development and accelerating growth and production of feeding animals; and 5) increasing the output and quality of feeding animal products. The dosage of these special substances is very small, generally according to a few percent of the formula feed to several parts per million (mg/kg), but the effect is very significant. According to some data at home and abroad, it is considered that the average efficiency can be increased by 5%-7%, sometimes up to 10%-15%.
