The physiological behaviors of dairy cows mainly include: eating habits, rumination, drinking habits, love habits, defecation urine habits and estrus behavior.

(1) Feeding habits When cattle eat, they often do not choose, gorging, hurrying to swallow without careful chewing, and ruminating and then chewing. Therefore, when feeding on the tuber feed, care should be taken not to oversize, over the garden, and it is best to cut it into slices or mash it and feed it. Otherwise, esophageal obstruction will occur easily. When feeding fodder, care should be taken to clear the nails, iron wire and other sharp metal foreign objects, otherwise traumatic net gastritis and traumatic pericarditis are prone to occur.

(2) Rumination habits When the cows eat at the time of eating, the chewing foods are swallowed by the initial chewing. The bolus enters the rumen and is stored in the rumen. After the alkaline saliva that has been brought in is softened and soaked in the rumen's water, the ruminants are regurgitated at rest. Rumination includes four processes of vomiting, chewing, mixing saliva, and swallowing. Cows generally begin ruminating 30-60 minutes after eating, with a duration of 40-50 minutes per rumination, 9-12 ruminations a day and a night, and 6-8 hours rumination. After eating, give enough rest time and quiet and comfortable environment to ensure normal rumination. Normal rumination is one of the signs of dairy cows' health. Rumination stops or the number of times is reduced. The time is shortened, indicating that the cow is already sick.

(3) Drinking habits Cows' daily drinking capacity is generally 4-5 times the dry matter intake of the diet and 3-4 times the milk production. For a 600 kg body weight and 20 kg milk daily, the dry matter intake of the diet should be 16 kg, and the amount of water a day is 60-80 kg. Drink more water in summer. Cows need to drink water within 2 hours after eating, it is best to allow them to freely drink water, water temperature 10-250C is appropriate, winter should drink warm water, summer should drink cold water.

(4) Love and clean habits Cows like to eat fresh feed and do not like to eat surplus feed. Therefore, less feeding should be added during feeding. After the lower trough, the remaining fodder in the feeding trough should be cleaned, and the trough should be rinsed clean before going down the grass. After the clearing, the remaining hay can be reprocessed after being used in the cool sun. Cows love to drink fresh, clean water, so the sink should be brushed regularly. Cows prefer a clean, dry environment. Therefore, the cowshed should be cleaned and rinsed after each trough.

The excrement in the stadium should be cleared in time to keep it flat, dry, clean, and prevent water accumulation. In the summer, pay attention to drainage.

(5) Defecation and urine habits Due to the large intake and drinking capacity of dairy cows, the number of defecate detritus is also large. Dairy cows are the livestock with the most defecation and urine output. An adult cow has about 30 kilograms of excrement during the day and night, which accounts for about 70% of the daily feed intake. The amount of urine discharged is about 20 kilograms per day, which accounts for about 30% of the amount of drinking water. Because milk steak excrement and urine output are large, the environment should be prevented from being contaminated during the production of dairy cows.

(6) When the estrus cows are in estrus, the first thing they do is show excitement, keep walking, and howling from time to time, with other cows chasing each other, hitting, spinning around in the stadium, then receiving close proximity to other cows, and then receiving other cow sniffing, and finally Susceptible when standing on other cows. The average duration of estrus is 18 hours, and the range is 6-30 hours. 70% of the time when estrus starts is from 7pm to 7am.
