The Technical Points of Feeding Blue and Green Materials for Livestock and Poultry in Summer

In summer, if the timing and methods of using green feed, the amount and manner of feeding are improper, it will lead to unbalanced nutrition of livestock and poultry, poor digestion and metabolism, impeded growth and development, even livestock and poultry poisoning, and livestock products with food safety risks. problem. In order to improve the safe feeding level of livestock and poultry green and green feed in summer and achieve the scientific and efficient use of the summer green feed growth season, the key technologies are now described as follows:

First, the efficient use of green feed

1. Kind of choice

In order to improve the safety and efficient use of green feed, according to the differences in the physiological characteristics of livestock and poultry and the characteristics of digestion and absorption of forage grass, suitable types of green feed can be selected to feed livestock and poultry. Ruminants such as cattle and sheep can choose to feed some green fiber feeds with high crude fiber content, and can use grass green feeds such as ryegrass, fescue, sudan grass, mexican corn, and imperial bamboo grass, and feed sweet Gao Hao et al. Pigs, rabbits, geese, etc. can use some of the crude fiber appropriately, and generally can choose green feeds with lower crude fiber content, such as European chicory, pine cone herb, Rumex, American corn pod, bitter wheat, etc.; Choose mature green fiber feed with higher crude fiber content and lower crude fiber content in the early growth stage, such as alfalfa, white clover, red bean grass, ryegrass, etc., and choose to feed pigs, rabbits, geese, etc. in the early stages of growth. . Chickens, ducks, etc. need green, blue, green, and less green food, so the green feed for feeding chickens and ducks should be used for early castration or grazing.

2. Scientific matching

(1) According to the differences in the content of nutrients in green feed, complementary diets are used. Different types of green feed contain different nutrients. The crude protein content of leguminous herbage is higher, and the content of crude fiber material is higher in grasses. The combination of the two pastures can form nutritional complements and increase the utilization of nutritive substances in the two herbage species. rate.

(2) According to the difference of nutrient and moisture content between green fodder and roughage, mutual reciprocal collocation can not only improve the palatability of crude fodder, but also can solve the problem of reducing or not ruminating the ruminant ruminant counts of ruminants such as cattle and sheep fed by green fodder alone feeding. The problem.

(3) According to the growth and production needs of livestock and poultry, the full-price combination of concentrate feed, roughage feed, and green feed is carried out. According to the nutrition characteristics of each type of feed and the nutritional needs of livestock and poultry growth and production, a fully mixed diet that meets the needs of livestock and poultry is produced to improve the production performance of livestock and poultry.

3. Modulation and processing

The preparation of cattle and sheep fed with green feed can be done by greening the green feed with the dried crop stalks. The specific method is: on the drying floor, first spread about 25-30 cm thick wheat straw, in the spread of wheat straw The green feed with a high moisture content of about 25-30 cm is laid, and then about 25-30 cm of wheat straw is laid on the green feed. After being laid, it is rolled with a stone mill or a roller to press out the juice of the green feed. It is absorbed by wheat straw. Pigs and geese fed on the green feed can be beaten and brewed. The specific method is: Beat the harvested green feed with a pulper. The green feed after beating can be directly mixed with dry powder or can be fed with roughage. Powder mixed fermentation, fed with concentrate feed.
