Fresh earthworms feed poultry best, and are nutrient-rich, high-protein feeds. The feeding amount of earthworm for chick can account for 5% of its daily diet, after one month, then add to 10-15% of the daily diet. For meat-chicken and laying chicken can account for 20% of its diet.
Ducks have a strong ability to digest earthworms, and the feeding amount of earthworms can be increased appropriately. Regarding Grass-fed animals such as cattle, sheep, rabbits, etc, earthworms can be processed into dry powder or fed after cooking. Because of its high protein content, the benefits of increasing yield after feeding are significant. For example, cows and goats can increase milk production by 10%-40% through feeding earthworm dry powder.
Be cautious when using omnivorous monogastric animals such as pigs, and generally do not feed more than 8% of the diet. The reason is that earthworms contain a kind of gamma formic acid, which can cause paralysis when overfeeding.
Generally, anglers like to use worms as bait, which shows that worms are attractive to fish. It can be said that all kinds of fish like to devour earthworms, especially at the juvenile stage. Catfish, carp, salmon and river eel among them are most earthworm lovers.
All in all, earthworms are all treasures. Not only are the protein and amino acids (23 types of amino acids in earthworms) extremely high, but they also contain lumbrokinase and proteases, which can inhibit bacteria and resist viruses. Turtles, frogs, scorpions, reptile, snakes and other special aquatic industries all use earthworms as important foods. Especially after feeding earthworms, frogs improve their appetite and change their Food Habits. It has a positive effect on the development of frog breeding industry.
