In spring, the temperature gradually warms up. After the green grass grows taller, the cattle and sheep can be grazing in spring to increase the nutrition and restore the stamina as soon as possible. For spring cattle and sheep good cattle, sheep should not use a loss of health of cattle and sheep grazing.
However, in early spring, early spring and spring, the grass sprouts grow taller and longer, relying on the old grass's own reserves of nutrients, can provide 18 days of nutritional needs to return to the grass, after which the new grass can absorb nutrients from the soil and maintain its own nutritional needs. . Premature grazing will hinder the growth of grass and reduce its ability to grow and produce grass.
Do not "running green" grazing cattle and sheep in spring, the weather is colder, the ground temperature is lower, the grass germination is slow, seemingly all over the grass, but young and small, cattle and sheep can not stand, not peace of mind to graze, want to send anxiously looked up From a distance, running around, looking for good grass, eating grass, can not find can not be left without moving, this is a "greed," "running green" phenomenon will make cattle and sheep consume a lot of physical strength. Therefore, grazing should not be carried out; grazing should be extended and grazing should be postponed.
However, there are more and more grazing grazing grassland farming households now growing more grazing grass raising livestock, wolfberry grass has high nutritional value, but not too much grazing. One is that saponins contain saponin, cattle and sheep eat too much, prone to acute bulging belly (ie, rumen blow), the treatment is not timely and easy to cause acute death; Second, fresh yarrow contains light-sensitive substances Yehong quality , cattle and sheep eat easily absorbed, white cattle and sheep skin see light will quickly cause inflammation of the skin, but also reduce the liver's detoxification function, so that the central nervous system disorders.
Without grazing, weeds, grasses and rain grasses are often exposed in the spring and morning and evening. The grass contains large amounts of moisture, especially if the cattle and sheep are empty in the morning when they are grazing. For example, if you eat a lot of grass, it is prone to bloating. Can easily 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, wait until the sun comes out to dry the grass on the frost, the grass heat and then grazing no later. You can also feed some hay or warm brine before eating every day. Rain grass has a higher moisture content, so don't let cattle and sheep eat rain grass.
The non-mixed herd is a herbivore although it is a herbivore, but each has its own habits. The method of grazing and the number of grazing, as well as the speed of walking and grazing, are not the same, even if the same animal is also based on sex, age and health Grazing grazing in the condition is not only convenient for management, but also improves grazing effects. In particular, males and females cannot mix herds and grazing. For example, in the spring season when male and female estrus are mated and bred, the male and female livestock must be grazing. Mixed grazing by male and female animals not only affects the feeding and rest, but also inevitably leads to free mating, repeated mating and inefficient mating, resulting in the occurrence of near-inherit and inferior species genetics, which reduces the value of use and shortens the service life. It is necessary to strengthen management. Improve grazing effectiveness and economic efficiency.
Do not disturb the herd Although the cattle and sheep are soft in nature, they are timid and frightened. They will panic if they have too loud or strange colors or sudden foreign objects. Occasionally, strangers are also afraid of anxiety. Therefore, grazing cattle and sheep must pay attention to safety, do not disturb the herd, if there is anxiety, it should be quietly called to make it quiet. Bad yak and nervous cows are often uneasy or kicking, and walking slowly when grazing does not make them frightened.
When there is no more poisonous weeds in spring grazing, we must pay attention to grazing in places where there are many poisonous weeds so as not to cause poisoning. Because spring poisonous grass germinates earlier than green grass, grows faster and grows taller, such as young and juicy juvenile poisonous celery, it is sweet, cattle and sheep are greedy green, prefer to eat, once you eat too much, it will poison quickly. There are many kinds of poisonous weeds, such as wolfweet, veratrum, wood thief, cocklebur, and hemp. Grazing in the forest and grassland should be paid attention to. In the early spring season, do not grazing banyan trees, green bar wood, etc. The tree shoots and leaf cattle are more like to eat, the toxicity of its metabolites is greater, and it is not easy to treat after poisoning.
Do not drink harmful sewage. With the increase in the amount of drinking water for the warmer cattle and sheep, pay attention to drinking clean well water, river water and mountain spring water. Do not allow drinking potash water containing pesticides and chemical fertilizers, drinking stagnant water like cysticid larvae, stinking water, drinking metal-contaminated water flowing out of the factory, preventing poisoning of cattle and sheep, and ensuring safe drinking of cattle and sheep.
