The optimum temperature for cows is 8-16 °C. The temperature in autumn and winter is low, and the management of the cows is not good, and the milk yield of the cows will decrease.
In the early spring, the doors and windows and the wall of the west and the north of the barn are tightly sealed to prevent the thief from invading; the doors and windows on the sunny side are to be curtained.
Increasing Feed Standards The energy produced by the cows in early spring is transferred to maintain body temperature. The cow's nutrition should be increased accordingly. Generally, the feeding standard should be increased by 10%~15%, that is, the mixed concentrate should be increased by 15%.
Drinking warm water in early spring, cows eat more hay. If you can't drink enough water, your appetite will drop, resulting in a decrease in milk production and even disease. Cows need about 5 kg of water for every 1 kg of dry feed. The suitable temperature for drinking water is: adult cow 12-14 ° C, milk production, pregnant cattle 15-16 ° C, yak 35-38 ° C. It has been proved by experiments that drinking 8.5 °C water in winter cows can increase milk production by about 8% than drinking water at 1.5 °C.
Supplementing salt and salt is one of the main components of gastric juice. In winter, the secretion of gastric juice increased, and the demand for salt increased accordingly. The daily supply of salt is determined by the weight of the cow and the amount of milk produced, and is generally supplied 50-100 grams per day. In addition to mixing 1% of the diet into the concentrate, you can also set up a salt tank to allow the cows to for free.
Strengthening exercise In winter, the cow house is under-illuminated, the air is not fresh, and the cows are not getting exercise. This will not only reduce the milk production, but also cause some diseases. Every day around noon, you should be driven out of the house to sunbathe and breathe fresh air.
Do a good job of cleaning the cow body 2-3 times a day to keep the body surface clean. Keep the pens clean and dry, place the soft grass on the place where the cows are lying, and often sprinkle some grass ash in the damp place, which can disinfect and prevent diseases, and has the function of moisture absorption and deodorization. In the winter, the cattle are dewormed once and vaccinated.
