How to keep cows cold and warm in winter

Strengthening the insulation of the cow house from four aspects--Cao Kaijun

Beijing Jingpeng Huanyu Animal Husbandry--Cao Kaijun

Mainly from the following four aspects to strengthen the insulation effect of the barn:

â—† Set the color plate thickness according to the specific situation. Based on the temperature difference between the inside and outside of the house and the heat generated by the cow itself, the thickness of the color plate used to construct the barn is calculated to ensure the temperature inside the barn.

â—†The electric inflatable wall is used for heat preservation of the barn. An electrically controlled inflatable wall is installed on the side wall of the barn, relying on the air between the two layers of covering as the wall. When the air pump is not working, the wall slides to the lower end, which is convenient for ventilation of the cow house. After being filled with gas, the wall covers the hole and plays a role of heat preservation. The ventilation system can be automatically adjusted by the control system by installing a temperature and humidity sensor in the barn to ensure the ventilation of the barn.

â—† Europe imported fans to ensure ventilation. The introduction of European fans, the two fans are forced air intake fan type. This type of fan is easy to install, safe and stable in operation, suitable for the regulation of the barn environment in cold regions; it can meet the various aerodynamic indicators in the house, low noise, effectively improve the air quality inside the house, and provide a comfortable living environment for animals; The fan is connected with the intelligent environment control software, which can fully control the flow of air into and out of the fan, so that the heat in the house is evenly distributed, and the humidity in the house is optimized. It is the best ventilation device to reduce the humidity of the cow house in the cold area.

â—† Ensure that cows drink warm water and increase milk production. Jingpeng can provide automatic electric heating water tank for cattle farms. The cattle farm can set the required water temperature according to the needs. The drinking trough effectively solves the problem of drinking water in the cattle farms in the northern part of the country, and avoids the heat stress caused by drinking cold water. The sink uses a high quality ball valve to effectively ensure the quality of the sink.

â—† Keep warm while keeping warm. Cows are animals that are afraid of heat and cold. If it is not a cold area, there is no need to consider the issue of insulation. If the cow house is well insulated, it will inevitably affect the ventilation. If the cow house is not well ventilated, the humidity will be very large, and the ammonia concentration will be very large. This is also a kind of damage to the cow, which is more than the cold effect.

Therefore, we advocate that a ventilation belt should be placed at the top of the barn to keep the air circulation of the barn; the side wall adopts a roller blind or a sliding window, and a ventilating port of 200-300 mm is kept under the cornice of the barn, and it is breathable all the year round. The purpose is to let the fresh air outside the house be replenished in time to remove the damp and dirty air of the barn, but the wind can not be directly blown onto the cow, which may cause cold stress of the cow. The vents under the mouth are only exchanged for the upper air of the barn. Because the height is generally more than 15 meters, the impact on the cattle is small.

The other is the gate, generally using electric roller shutters to control the opening and closing time, try to avoid wearing the wind. In the building, the composite polystyrene board used on the top of the barn has a thickness of more than 100 mm.

It should be emphasized that at the right time, for example, when the temperature is high at noon, the barn still needs ventilation, and ventilation is very important.

◆Automatic electric temperature control drinking water tank to ensure that cows drink 5-15 °C. This temperature range is the normal drinking water temperature range for cows, not to say that the higher the temperature, the better. Cows drinking warm water in winter can reduce energy consumption and increase feed conversion rate. Zhong Bonong's drinking water tank is automatically temperature controlled. The cattle farm can set the required temperature according to the specific conditions. When the water temperature reaches the set temperature, it will automatically turn off the electricity to stop heating and become heat preservation.

â—†The delivery room and the yak house are equipped with heating. Heating pipes or radiators, in addition to taking into account cattle, also take into account the heating problems of workers such as veterinarians.

The yak is relatively sensitive to the cold. If it is minus 40 ° C, the damage to the yak will be greater.犊牛舍 We generally use a small barn, set up a large bed, padded on the top, the ground below to do the hardening treatment, then add the floor heating, surrounded by heating pipe, the temperature can be controlled at 12 °C when sealed, if it is daytime Ventilation, the temperature can also be more than ten degrees higher than the outside temperature. Yak is very comfortable in such an environment.

We are building a constant temperature cow room for the Feihe. This kind of barn is much better than the general natural ventilation barn because it is mechanically ventilated. We plan to complete the construction of all the projects by the end of December.

Increasing the energy concentration of lactating cow diet--Wang Zhaojun

â—†Automatic insulation tank ensures that the cows drink warm water. We are now using the Terry Drinking Fountain to automatically guarantee the water temperature.

â—† Increase the energy concentration of lactating cow diet: add one or two corn noodles to one kilogram of milk to increase the energy concentration of the diet. For example, one kilogram of milk is usually given to six or two mixed feeds. When the temperature drops, one or two cornmeal will be added to become a mixed feed of seven or two.

Yak will take special care, the replacement of weed litter will be more than the summer, and the other is heating and heating, the general temperature can be controlled at 7-15 °C. Other barns have no special heating measures, mainly relying on the cows themselves to produce heat.

â—† Do a good job in the windproof insulation of the cow house. The barn here may not be the same as the south. We use a 37 cm thick brick wall for better insulation. The two windows are generally closed in winter, wind and cold, but also pay attention to the cow house while keeping the wind. Ventilation.

The sports field is doing a good job of windshield wall---Dou Cheng

◆ The cow house should be properly ventilated at the same time. When we are coldest in winter, the temperature can reach minus 28 °C, the wind is relatively large, and it can reach the seven-level wind, so the environmental control of the barn is very important. It is very important to protect the cow from cold, but the closure is too strict. After the bovine urine feces are volatilized, the concentration of ammonia in the air is too large, which affects the air quality, so it is necessary to leave the skylight for ventilation. The other is windproof, especially against thieves.

â—†The sports field is a good windshield wall. Here, the northwest wind is generally blown, and the cowshed is generally east-west, so that the west side of the playground can temporarily make a wind wall about 3 meters high. If the cow house is not in bed, the cow always goes out to the playground, and a windshield can cover the wind to a certain extent. In addition, the sports field is squatting in the snow and ice, ensuring that the cow's breasts are not exposed to ice and snow.

â—† Provide clean, soft bed for cows. Our cattle farm was originally padded with dry sand. Now we mainly use dried cow dung, which is used to collect dried cow dung in summer and autumn. In fact, the leftover material is also a good litter. Generally, the remaining feed of the lactating cow will be eaten by the reserve cow, but it is impossible to eat very clean. We can collect it and use it as a litter after drying. In short, try to let the cows lie in a comfortable place, what can be determined according to the actual situation of the cattle farm.

â—† The feed formula is basically not much changed. Because as the climate becomes colder, the feed intake will increase, and the whole digestion and metabolism will accelerate. In fact, it will make up for the extra energy consumption of this part, and the physiology of the cow will make some adjustments. Adjusting the feed formula in winter may have a certain effect, but I personally think that the effect is not too big.

By the same token, all large dairy farms in the dairy industry in the United States, such as the United States, are fed a feed formula based on high feed intake and low intake of low-yield cattle, which is regulated by the cow itself.

◆24 hours automatic temperature control sink to ensure water temperature 10-15 °C. We use a square automatic temperature control sink with a temperature of 10-15 °C. The water can't be too hot. If the water temperature is more than 30 degrees, the cow will drink because of sweating.

â—†The production room is equipped with a "fireplace" and padded grass. We have made a stove similar to a fireplace in the production room, as well as a "fire wall", which may be rare in other places, and the heating effect is very good. There is no bed in the delivery room, and the entire ground is covered with hay.

â—† Less water when milking, add more glycerin to the medicated bath. When milking, you can't use the same amount of water as the summer. It is mainly wiped with a towel. Try not to let the breasts get too wet when milking. When you dilute the medicated bath, you can add less water, add something like glycerin, and moisturize the breast. Try to keep your breasts dry after milking, and rub some petrolatum if necessary.

In addition, a closed milking passage is provided to play a role in preventing cold and wind. I can't feel uncomfortable in the process of going to the milking parlour.

In some places, after putting milk, put a belly pocket on the breast, the effect is good, but too many cows are very troublesome, like a small-scale cattle farm can be considered.

â—† Adjust the time of the herd in the stadium. In the summer, the cows are usually placed at the playground at 6:30 in the morning. In the winter, the cattle are laid out later in the morning, usually after 7 o'clock in the sun. Especially on windy days, it is necessary to come back to drink a little water, if there is a windy day. At night, the time of the cow is also relatively early, around four or three and a half.

◆ The barn has double-layer steel windows and curtains. The lowest temperature here is minus 18 ° C, so the winter barn will be added with a cold curtain, the window is double-layered steel, fully enclosed in winter. The aisle in the middle of the barn should be closed at any time, otherwise the ground will easily form ice. There is also the diligence of clear manure, when the manure is cleared, the doors and windows should be closed. After the manure is cleared, the cows will not open the curtain when they are not in the barn. The ventilation is very eight points. In order to prevent the house from being too humid, the roof of the barn should be kept ventilated.

â—†It is snowing even if it is snowing. If you encounter snowy weather, the playground should be cleared of snow in time. In the channel where the cow walks, sprinkle some non-slip sand or ash to prevent the cow from falling when it goes, and enter the station milking passage to do some anti-slip measures.

â—† The difference between drinking warm water and not drinking warm water is 3%. The cattle and calves in the delivery room were changed to warm water in the winter, and the boiler was heated and piped to the barn.

â—† Dairy cows add one kilogram of concentrate per day.

â—†The sports field is made of windshield. The perimeter of the sports field should be well protected against wind, or some windshield can be done, especially for calves and cattle in the delivery room. The distance of the windshield should not be too far, and the isolation belt should not be formed too far. It does not work about two or three meters away from the sports field.
