(a) pay attention to diverse collocations, nutritionally complementary colloquialism: livestock eat a hundred kinds of grass, no material is also available. Different pasture varieties have different nutritional characteristics. If they are fed alone, they can easily lead to nutrient imbalance. Grasses are rich in carbohydrates, legumes are rich in protein, and leafy grasses are rich in vitamins and minerals. Single feeding of grasses can easily lead to lack of minerals, and single feeding of legumes can cause swelling. Therefore, these pastures should be properly fed with livestock and poultry, and if they can be matched with wild weeds, leaves, and aquatic plants, the effect will be better.
(B) pay attention to the best nutritional period harvest feeding when the grass feed for cattle, sheep should be harvested at the beginning of the ear, feed pigs, chickens, rabbits, geese should be harvested before heading; legumes feed cattle, sheep When it is appropriate to harvest at the early flowering stage, pigs, chickens, rabbits, and geese should be harvested before flowering; leafy grasses should be harvested during leaf clustering when they are fed to livestock and poultry. In this case, protein, vitamins, and other nutrients have the highest levels.
(C) pay attention to training feeding on some poor palatability, smelly pasture, such as Rumex K-1 hybrid sour, pine cone herb, Russian feed, etc., should be fed during the initial feeding. The training and feeding method is to first stop the livestock and poultry for 1 to 2 days, chop the pastures and feed them together with other pastures and concentrate feeds that the livestock and poultry eat, and the first blending amount is about 20%, and then gradually increases. Generally, after 3 to 5 days of training, the livestock and poultry can adapt to many feedings.
(4) Attention should be paid to the dry and green dry forage grass fiber and low lignin content, which is not conducive to the rumination of cattle and sheep. It should be used to feed ruminant livestock such as cows and sheep. For 30% of the diet, winter hay accounts for 70% of the diet. For grasses with high moisture, such as Rumex, chicory, etc., they should be air-dried until the moisture content drops below 60% and then fed. Otherwise, livestock diarrhea may easily occur.
(E) Note that the processing methods used to feed cattle and sheep can be cut longer, with 8 to 10 cm is appropriate, feeding rabbits, goose can be cut to 2 to 3 cm, while feeding pigs, chickens are chopped or beaten.
(6) The feeding amount of the green feed should be different depending on the species. Generally suitable for the amount of feeding: dairy cows daily 30 to 50 kilograms, sheep 10 kilograms daily, goats 8 to 9 kilograms daily, rabbits, geese daily 2 kilograms, chickens 0.1 kilograms per day, pigs 5 to 7 kilograms per day.
(7) Attention to anti-poisoning One must prevent hydrocyanic acid poisoning from green feed. Sorghum, corn, sudangrass, and yucagu grasses contain cyanogenic glycosides, which are fed to the mouth through cattle and sheep. Under the conditions of saliva and temperature, hydrocyanic acid can be produced through the action of lipolytic enzymes in plants. In the rumen, through the role of rumen microorganisms, hydrocyanic acid enters the blood to cause poisoning. Therefore, the seedlings of the above pasture cannot feed cattle and sheep. Second, prevent organic pesticide poisoning. Pastures, vegetables, green corn, and field weeds that have just been sprayed with pesticides cannot be immediately fed to livestock and poultry. After a certain period of time (about 1 month) or after heavy rain, the amount of drug residues disappears before feeding.
