Due to the limited availability of fresh green fodder and reduced sunlight in spring, prolonged feeding of livestock and poultry can lead to vitamin deficiencies. This deficiency can cause metabolic disorders, slow growth, weakened immunity, and even illness or death. To prevent these issues, it is essential to provide vitamin supplements during this season. In this article, we will introduce a simple and effective vitamin supplement that farmers can easily prepare at home. Below are the production techniques and usage instructions.
The production of germinated feed typically uses cereal grains such as barley, oats, corn, and rice, with barley being the most commonly used. The process is similar to sprouting beans. First, the seeds are cleaned and washed in warm water, then dried. Next, they are soaked in water at 20°C to 25°C, wrapped in gauze or cloth, and sprayed with warm water (around 30°C) 4 to 6 times daily. They should be gently turned to ensure even moisture. After 2 to 3 days, small roots and sprouts begin to appear. At this point, the covering material can be removed, and the sprouts should be rinsed with clean, warm water in the morning and evening. Within 3 to 5 days, the sprouts will turn green and can be harvested as needed.
Germinated feeds are highly nutritious. During the germination process, some starch is converted into maltose, and proteins break down into easily digestible amino acids. Additionally, levels of carotenoids, riboflavin, and vitamin E (tocopherol) significantly increase. These nutrients are vital for animal health. For example, one kilogram of sprouted barley contains approximately 28 mg of vitamin A-carotene, 250 mg of vitamin B2, and 17 mg of nicotinic acid (vitamin PP). This transformation greatly enhances the nutritional value of the original grain, making it an excellent source of vitamins for livestock and poultry.
The timing of feeding germinated feed depends on the intended purpose. If the goal is to supplement the B-vitamin complex and improve palatability, the sprouts should be fed when they reach 2 to 3 cm in length. For higher levels of carotenoids, it's best to feed them when the shoots grow to 8 to 10 cm.
In practice, germinated feed has proven beneficial for various animals. For breeding females, 150 to 250 grams per day can help stimulate estrus, support pregnancy, and increase milk production. For males, 100 to 200 grams per day can enhance libido, improve semen quality, and boost breeding success rates. Young animals, such as pigs, calves, or chicks, benefit from 30 to 40 grams per day (for pigs, 10 to 20 grams; for chicks, 3 to 4 grams), which promotes growth, strengthens immunity, and improves survival rates. Laying hens fed 10 to 20 grams per day show increased egg production, better fertilization rates, and improved hatchability. Germinated feed is also ideal for sick or weak animals, providing essential nutrients to aid recovery.
When feeding, the sprouts can be cut into small pieces, chopped, or mixed directly into their regular diet. Animals can then eat freely. This method is both practical and effective, making it a valuable addition to any farm’s feeding strategy.
