The growth and use of forage grass is greatly affected by the season
In winter, forage grass is yellow, contains less nutrients, and livestock lack grass. In warm season, forage grass grows vigorously and nutritious. Grass can not eat more livestock. Therefore, in order to avoid weaknesses and make full use of the forage grass in the warm season, the livestock can be fed in the winter by being cut, dried, crushed and processed into grass pellets.
High feed conversion rate
In winter, grass particles are used to feed livestock and poultry, and less forage can be used to obtain more meat, eggs and milk.
small volume
Grass pellet feed is only about 1/4 of the raw hay volume, which is convenient for storage and transportation. Less dust is beneficial to the health of people and livestock. It is convenient to feed, which can simplify the feeding procedures and create conditions for intensive and mechanized livestock production.
Increase palatability and improve forage quality
For example, grass crickets have a special odor of coumarin, and livestock are somewhat unpleasant to eat. However, when they are made into grass granules, they become forage grasses with high palatability and high nutritional value.
Expand feed sources
Such as Caragana, You Ruoyu, Yangchai, etc., their branches rough, after smashing processed into grass particles, it became a livestock favorite fodder. Other processed grass particles such as crop by-products, clams, straw, and various leaves can be used to feed livestock and poultry.
The most critical technique for processing grass particles is to regulate the moisture content of the raw materials. First, the moisture content of the raw material must be measured, and then the water content must be adjusted to the required moisture content. According to the measurement, the use of legume forage grass particles, the best moisture content of 14% to 16%; grass forage grass is 13% to 15%.
The processing of grass particles usually uses pellet feed mills. The grass powder is stirred and squeezed during the pulverization process. Under normal conditions, the temperature of the pellets just coming out of the sieve hole is about 80°C. From the high temperature to the room temperature, the water content is generally reduced by 3% to 5%. Therefore, the water content of grass particles after cooling does not exceed 11%~13%. Due to the low water content, it is suitable for long-term storage without mold deterioration.
According to the nutritional requirements of various livestock and poultry, it can be formulated into grass granules containing different nutrient components. Its particle size can be adjusted by the pulverizer and processed as required.
Collagen is the most abundant protein in mammals, accounting for 25% to 30% of the total protein. It is widely present in all tissues from the body surface of lower vertebrates to mammalian bodies. Collagen monomers are long cylindrical proteins with a length of about 280 nm and a diameter of 1.4–1.5 nm. It consists of 3 polypeptide chains that are supercoiled around each other.
