First, carefully reared
After the cow is pregnant, it is necessary not only to maintain its own nutritional needs, but also to provide nutrition for the growth and development of the fetus, and also to store a certain amount of nutrients to ensure postpartum lactation. Therefore, 1 to 2 kilograms of concentrate should be fed every day, and good conditions should be used to feed mixed feed: corn, cardamom cake, rice, cottonseed cake, rapeseed cake, rice bran, and salt in proportion. And to ensure that time, quantitative, and less to Tim Tim, never fed mildew degenerate feed, drinking water should be healthy, it is best not to drink water and drink frozen water, in the rain and snow days, insist on cattle cattle grazing, eat grass, improve The amount of exercise is conducive to enhancing the health of the cattle body. Grazing should be selected in the leeward sunny bushes, and the pregnant cows should not be allowed to eat falling frost forage.
Due to the fact that most of the winter season uses hay, straw, and other coarse materials as the main material, it is necessary to do a good job of adjusting the feed. If the ammoniated feed can be used to feed cattle, the palatability of the feed can be enhanced and the nutrients of the feed can be increased. Insufficient, can use urea feed, can make up for lack of protein. The amount of urea used is 40 grams per 100 kilograms of body weight per day.

In the middle of pregnancy, cows should gradually reduce the intensity of military exercise, especially in the military service. It is forbidden to draw cold whips, rush to live, turn sharp corners, and to slow down the service, and stop working for 4 to 5 weeks before labor to prevent miscarriage. For the pregnant cows raised in the pens of the entire family, they will not be encumbered. When the sun is sunny, they must drive the cows to exercise properly, enhance their physical fitness and prevent dystocia. If dystocia occurs, they must be promptly treated.
Grow lighting can be one of the most essential factors to successful plant production in a commercial greenhouse because grow lights help to lighten shady spots and propagation areas in the greenhouse. If you are growing tropical plants, you may need to set up grow lights if the plants don't get at least eight hours of sun each day. Most crops benefit from supplemental lighting, when increased growth and quality is converted into added revenue. We provide Growing Light and complete systems for your greenhouses.
