Four tricks can increase the production of velvet.
1. Take a goose as an example, adding 0.9 grams of sulfur iodine, 1.5 grams of silkworm sand, 0.6 grams of Poria cocos and 0.9 grams of probiotics to its diet can be plucked 15 days in advance.
two。 Immediately after pulling out goose down, vitamin B12 was injected intramuscularly once a day, half a dose each time, for 4 times, which played a significant role in promoting the growth of goose down.
3. After plucking down, wipe the goose with 50 degrees white wine or ginger juice once a day for 3 days, which can increase the down yield of geese.
4. Feeding geese with 10% feather meal, 5% bone meal, 4% fish meal, 20% soybean meal, 20% corn meal, 0.2% amino acid, 0.8% polyvitamin, 25% pine needle powder and 15% sophora leaf powder can increase the down production of geese.
