When oat grass is used for grazing, it is suitable for preparing hay after mowing because of its high sugar content, good palatability, tall plants, thin stems and many leaves. The crude protein content is moderate and the nitrogen-free extract is rich. The content of crude fiber is equivalent to other plant fiber sources. Compared with other plants, the content of neutral detergent fiber in oat hay is lower, and it is more palatable than other hay containing high neutral detergent fiber. Oat hay tastes sweet and is rich in highly water-soluble carbohydrates (WSC≥ 15%, compared with 9% for imported alfalfa). The sugar content of oat hay is similar to ryegrass, but it is more palatable and feed value, and it is known as "sweet hay". Cutting and forage should be at heading stage, when protein content is high and grass yield is high; The prepared hay can be harvested at flowering stage, which can increase the harvest. When cultivated in fertile soil, it can be mowed 3-4 times a year with good management conditions, and fresh grass can be harvested 30-37.5 t/ha. Grazing begins when the plant height is 20-25cm, and grazing can be carried out 4-5 times after one year. The grass yield is the highest in the second year after planting grass, and the growth potential is obviously weakened in the fourth year. If it is not well managed, it will disappear completely. Cultivation points: Oats can be sown in spring (March) or autumn (September) in the south, but in spring (April) in the north. Can be used for short-term grassland (2-3 years). In order to facilitate management, it can be drilled, with row spacing 15-25cm and sowing amount of 30-45 kg/ha. Oats can be mixed with other grasses, and the mixed grasses should have similar growth periods and not grow very fast, such as Duckweed, Tall fescue, clover and red clover (T. prate-NSE), just like Italian Lolium multiflorum. When harvesting seeds, the color of the ear should change from green to yellow, and 375-750 kg/ha can be harvested. If the seeds fall off easily, they should be harvested in time. Seeding with fresh seeds can improve the survival rate of seedlings. In addition, the average potassium content of oat hay is less than 2%. This is very important for dairy farmers to distribute feed rations. Lower potassium content can also reduce the risk of milk fever caused by eating feed including oat hay.
In the feeding process of dairy cows, the positive combination effect of oat grass and leguminous alfalfa is also good. Reasonable utilization of alfalfa grass (Leguminosae) and oat grass (Gramineae) in dairy cows' diet will maximize the utilization efficiency of roughage. It is found that the degradation of alfalfa and oat grass in rumen can only produce isobutyric acid, valeric acid, small peptides and amino acids needed for the growth of crude cellulose decomposing bacteria. By stimulating the activity of crude cellulose decomposing bacteria, the digestibility of fiber substances and rumen environmental physiological parameters (such as branched chain fatty acids, rumen ammonia nitrogen, etc.) are improved in dairy cows. ) have improved.
After adding oat grass to dairy cows' diet, the number of zoospores of rumen fungi increased. The mixed use of alfalfa and oats is easy to ferment, which can promote the colony formation of cellulose decomposing bacteria and improve the utilization efficiency of roughage, which proves that there is a positive combination effect between alfalfa and oats. Therefore, adding oat grass to dairy cows' diet can not only meet the nutritional needs of dairy cows and improve the quality of dairy products, but also significantly improve the utilization rate of roughage for dairy cows. Reduce the feeding cost. Efficacy: antiperspirant; Accelerate delivery
