Spring grazing cattle and sheep technical essentials
With the advent of spring, the temperature is getting warmer. After the grass grows taller after being green, when it is able to eat more than half full, it can spring cattle and sheep timely to increase nutrition, so as to restore the physical strength of cattle and sheep as soon as possible, so that the cow ewe Smooth farrowing, with more milk to nurture the young, to ensure that the whole live full strength. Therefore, for spring cattle and sheep, farmers are reminded to remember "12 no." First, but early spring cattle and sheep grazing early spring, not only easy to "running green", damage grassland, grassland degradation, and more importantly, early spring, back to the grass sprout grow taller, relying on the old grass itself reserves of nutrition The nutrients needed for returning to the grass for 18 days can be absorbed from the soil by the new grass after 19 days to meet the nutrient needs of the return grass, so that the grass grows taller and grows longer, in order to protect the grass and improve the regenerative capacity and production of the grass. Grass volume. If grazing is too early, the nutritional needs of the grass will be destroyed, and the growth and development will be hindered. It will be impossible to reduce the grass's ability to grow grass and its grass production, thus accelerating the degradation of grasslands. Second, non-free grazing grazing cattle and sheep is a good way to save money, increase economic efficiency and reduce the cost of raising livestock. But it is not free to grazing, and it is impossible to drive cattle and sheep into the pasture. The harm is great. First, it is not possible to give full play to the high efficiency of grass and waste of grass. Second, grazing every day on this pasture increases the chance of infection by parasites. Third, grassland is severely trampled and grassland is degraded quickly. The village should be divided into its own use of grass and grassland, and then divided into a number of grazing areas, the implementation of advanced animal husbandry and grazing law, the herd fixed, round playback of animal husbandry. In this way, the grassland can be fully utilized, the grassland per unit area can be increased, the grass can be trampled, the grass can grow well, and the amount of grass production can be high. This can effectively increase the production performance of milk, meat production, wool production, litter production, and labor use of cattle and sheep. Economic benefits, and reduce the chance of parasite infection. Therefore, cattle and sheep cannot be freely grazing. Third, do not "running green" grazing early spring grazing cattle and sheep, cool climate, low ground temperature, grass sprouting slow, seemingly green grass everywhere, but young and small, it is the distance to see the grass but no, is not a year in the blue and white The most difficult season. Grass hay is running out, old grass is not enough, new grass is not yet growing up, cattle and sheep are not able to stand, and they are not at ease eating grass. They want to look up anxiously and look away, running around, looking for good grass, long grass and eating. It is a phenomenon of "greediness" and "running green". Because of this psychological dominance, desperate to run, not only eat enough, but also consume a lot of physical strength, most likely to make cattle and sheep tired, and even dragged to death; both stepping down the grassland, but also dragged the cattle and sheep. Therefore, grazing should not be carried out, grazing should be extended, and grazing should be postponed until the grass grows high again. It is also possible to grazing the hay on the hillside first, and then grazing after the grass grows high on the southern slope. Will not "run green". Fourth, no more grazing barn grass farmers in the farming area is now growing more and more grasshopper raising livestock, barnyardgrass high nutritional value, but not too much grazing. One is that saponin contains saponin, cattle and sheep eat too much, prone to acute bulging belly (that is, rumen blowing or bloating), the treatment is not timely and easy to cause acute death; Second, fresh yarrow contains photosensitive substances Leaf red quality, cattle and sheep eat easily absorbed, white cattle and sheep skin see light will quickly cause skin inflammation, itching irritability, but also reduce the liver's detoxification function, so that central nervous disorders, it should not be too much fresh grazing Weeding grass so as not to cause serious consequences and cause undue economic losses. Fifth, do not grazing frost Dew and rain grass because of the early spring cold air, morning and evening often frost, grass, large water, especially in the early morning empty stomach, such as hunger to eat a lot of frost-dried dewy grass, it is easy The occurrence of bloating is not timely, and it is easy to swell. Therefore, it is not appropriate to grazing frost weeds. The prevention method is to put "hot grass", that is, to grazing every day to return to the early return. After the sun comes out, the frost on the grass is dried, the grass is bred and then grazing is not late, and the cattle and sheep eat well and do not fall ill. Also resistant to hungry. The second is to feed some hay each day before going grazing, which can absorb the water in the grass so that it can be digested without swelling. Or just before the animal is grazing, drink the appropriate amount of hot salt water, which can play a good role in anti-fermentation. In the same way, when it rains on a day, the moisture is greater. The grass is indigestible in the stomach, and it is easily fermented. If you love to swell your belly or squat, as long as you don't grazing the grass, the cattle and sheep are safe.
