Early spring cows prolific six points

In order to promote the prolific milk production of dairy cows in the early spring, farmers should pay attention to the following six points: The critical temperature for dairy cows to produce milk is around 20°C. It is very difficult to reach this temperature in the early spring, except for raising the cows in a greenhouse. However, the temperature should be kept at about 10°C at least. Provide enough nutrients for the diet. On the basis of feeding enough hay or silage, dietary nutrients should be properly increased. When there is no green feed, chopped carrots, potatoes, or fresh Chinese cabbage leaves should be fed 35 kilograms a day. On the basis of normal milk production, each mixed 3 kg of milk should be fed with 1 kg to 1.5 kg of mixed concentrate to ensure the need for milk production. Supply plenty of warm water. If you give cows cold water in the early spring, the cows will consume a lot of body heat and reduce the milk production. Insufficient drinking water will also cause some diseases. It should be noted that a sufficient supply of warm water of about 16°C is generally used to boil the water in the semi-warm bottle with water drawn from the well and allow the cow to drink. Keep your health. In order to make the peninsula dry and conducive to heat preservation, it is necessary to provide more cushions and bedding. To remove excrement in time, and often sprinkle some lime powder or ash in the house, this will not only reduce the humidity within the house, but also can prevent and cure diseases, which will help increase milk production. Adhere to the sun and exercise. In sunny weather, allow the cows to exercise for at least two hours every day, and then bring them to the sun where the leeward sun rises to strengthen the blood circulation, help digestion, and increase milk production. Carefully brush the body of the cow. Brushing the body of the cow can increase the milk yield. Every day, it is necessary to carefully brush the body hair of the cow once or twice.

Profilometer

A profilometer is a precision equipment used to measure the shape of various mechanical parts' lines and cross-sectional contours. The instrument workbench adopts high-precision horizontal air floating track and rolling vertical track, with high movement accuracy, good stability, and long service life; High measurement efficiency, simple operation, suitable for use in workshop inspection stations or measurement rooms.

The instrument workbench adopts high-precision horizontal air floating track and rolling vertical track, with high movement accuracy, good stability, and long service life; High measurement efficiency, convenient card installation, simple operation, suitable for use in workshop inspection stations or measurement rooms. This instrument can further develop software according to the needs of users, meet their measurement shape requirements more widely, and is equipped with various equipment components for users to choose and use according to their own requirements.

A Profilometer is a precision equipment used to measure the shape of various mechanical parts' lines and cross-sectional contours. In the bearing industry, it is possible to measure the contour shapes of various rolling elements and raceways, such as protrusion, contact angle, surface curvature radius, and reference part angle. In the mechanical industry, it is possible to measure the straightness, line profile, parallelism, inclination, and angle of various parts. Especially suitable for measuring the appearance of pistons in automobiles, tractors, and motorcycles. The production instruments of this research run enterprise are controlled by microcomputers, which automatically achieve measurement cycles, eliminate installation errors, directly display the shape and parameters of the measured parts, and can print graphics and data for product quality testing and process analysis.
