Lion-headed goose feeding technology
Ryegrass is a highly nutritious and palatable feed for geese, with soft leaves that leave no fluff. It is considered one of the best feeds for geese, as they can consume up to 100% of it. Typically, each goose reaches a weight of 70 kilograms after 70 days of feeding, requiring about 180-200 kilograms of fresh ryegrass during this period.
(1) Breeding Methods for Ryegrass-fed Geese
1. Feeding young goslings: Goslings around one month old have underdeveloped digestive systems, so their ability to digest and absorb nutrients is limited. Fresh ryegrass should be cut into small pieces, about 1-2 cm in length, and mixed with a small amount of concentrate (grass to concentrate ratio of approximately 10:1—10 kg of grass with 1 kg of chicken feed). Feed them 4-5 times a day, gradually increasing the amount as the goslings grow older.
2. Feeding Chinese geese: During their second month of life, geese grow rapidly and require large amounts of food. At this stage, fresh ryegrass should always be available. Each goose can consume 15-20 kg of ryegrass daily, while the amount of concentrate should be reduced. A mix of 14 kg of ryegrass with 1 kg of concentrate is sufficient to meet their nutritional needs. The grass should be cut into 2-3 cm pieces.
3. Feeding larger geese: After 60 days of age, each goose can consume 2-2.5 kg of ryegrass per day. The concentrate can be further reduced, and the amount of cooked sweet potatoes can be increased to help with fattening.
(2) Key Points for Rye Grass Goose Rearing
1. Goslings can start eating chopped ryegrass from their third day of life. When using ryegrass, it's important to supplement with concentrates. It's not advisable to feed only with grass. Always chop the ryegrass before feeding.
2. Freshly harvested ryegrass has high moisture content. Allow it to dry slightly (after dew or rain) before feeding to prevent geese from having loose stools.
3. When large quantities of feed are provided, geese may not finish all at once. Leftover grass can be trampled, leading to waste or pollution. To minimize this, use a small amount of straw along with the feed to reduce waste.
4. Add an extra meal to promote growth. Lionhead geese have strong appetites and tend to get hungry quickly. Provide a midday meal with some concentrate to speed up growth, improve fertility, and shorten the meat production cycle.
5. During the late growth phase of ryegrass, before spring plowing in the following year, any remaining fresh grass can be harvested once and stored as silage (for silage methods, refer to other resources).
(3) Testing of Ryegrass-based Goose Rearing and Meat Production
To better understand the body size and meat yield of lionhead geese, and to explore the economic value of raising geese on winter-planted multi-flower ryegrass, three experimental sites were set up in Houjia, Chikeng, and Yangdong of Lianrao town from December 16, 1999, to January 18, 2000. The results showed that meat geese raised under semi-grazing conditions with appropriate compound feed reached weights between 31 and 64 days. On average, ryegrass-fed geese gained 92 grams per day compared to those fed green vegetables. The carcass slaughter rate improved by one percentage point, and economic income increased by 74 yuan. For every 121 kg of ryegrass, meat geese gained 1 kg in weight.
2. Hybrid Pennisetum Goose Technology
Hybrid pennisetum is an excellent feed for goslings and adult geese. When the stems are still short, geese can graze freely or the grass can be cut into 1-2 cm lengths. It is typically mixed with other feeds at a ratio of 20%-50%. A mix of 75%-80% of this grass with other feeds is commonly used.
3. Gram Straw Goose Feeding Technology
Gram straw is a perennial legume forage with high nutritional value, containing about 15% crude protein—double that of rice. It is considered high-quality feed for geese. However, it usually yields only one or two harvests per year, with low productivity. In Daejeon, typical yields are around 400-500 kg of hay, while high-yield fields may produce 800-1,000 kg.
The stems of gram straw are tough and fibrous, making them difficult for geese to digest. Therefore, direct green feeding is generally not recommended. The main approach is to grind the dried stems and flowers with corn, bran, or wheat flour in a ratio of 15%-20% (i.e., 80%-85% concentrate and 15%-20% grass powder) to create a balanced feed for geese.
