Four practical methods to increase goose down yield

1. Taking one goose as an example, add 0.9 g of finely ground sulfur and iodine, 1.5 g of silkworm droppings, 0.6 g of Smilax glabra (tufuling), and 0.9 g of growth promoter to its daily diet, which can advance plucking by 15 days.

2. After plucking goose down, immediately inject vitamin B12 intramuscularly, once a day, using half an ampoule each time, for 4 consecutive times, which has a clear effect on promoting goose down growth.

3. After plucking goose down, rub the goose's body with 50-degree baijiu or ginger juice, once a day, for 3 consecutive days, which can increase the goose's down and feather yield.

4. Feed geese with 10% feather meal, 5% bone meal, 4% fish meal, 20% soybean meal, 20% corn meal, 0.2% amino acids, 0.8% multivitamins, 25% pine needle meal, and 15% pagoda tree leaf meal, which can increase the goose's down and feather yield.
