The purpose of cow estrus identification is to find the estrus should be equipped with cows in a timely manner, correctly grasp the breeding time, timely breeding, to prevent mis-match with the allocation. It has been proved that properly controlling the estrus and ovulation patterns of cows and grasping the optimal breeding season for timely breeding is one of the important measures to increase the conception rate of cows. Methods for identifying estrus in cows include external observation methods, test methods, vaginal examinations, and rectal examinations. 1. External observation method External observation method is the main method to identify the estrus of cows. It mainly judges the estrus status according to the external performance of the cow. Cows are often irritated when they are estrus. Appetite and milk supply are reduced. Tail roots are raised. Chasing, crawling across other cows and accepting cows. Creep cows crawling across other cows, squeaking and dropping urine, having bull mating. action. The pudendal area is red and swollen, leaving mucus out of the vulva. 2. The test method The test method is based on the cow's climbing situation to find estrus. This is the most common method. This method is particularly suitable for breeding herds of herds. It can save manpower and improve the estrus identification. There are two kinds of test methods: One is to put the bull that has vas deferens into the herd and place it in herd during the day. At the trial, the male and female were separated at night, and the estrus status of the cow was judged based on the bull's chase climbing situation and the extent of the cow's acceptance of the climb; the other was to approach the trial bull to the cow, such as the cow bullying on the bull, and A bent back posture indicates that the cow may be in heat. 3, vaginal examination method vaginal examination is to use vaginal opener to observe the vaginal mucosa, secretions and cervical changes in the mouth to determine heat or not. Estrus cows vaginal mucous membrane congestion flushing, smooth and moist surface; cervix mouth congestion, relaxation, soft opening, discharge a large number of transparent fibrous mucus, such as glass rod-like (commonly known as hanging wire), not easy to break. Mucus is initially thin, gradually thickens as the estrus time passes, and the amount changes from less to more. By the end of estrus, the amount gradually decreased and the viscosity was poor, the color was opaque, and sometimes it contained pale yellow cell debris or trace amounts of blood. The non-estrus cows have a pale, dry vagina, and the cervix is ​​closed and no mucus flows out. 4, rectal examination method for rectal examination, the examiner must be short nails, polished, painted on the arm lubricant, first touch the anus, then the fingers together into a cone, with a slow rotation into the anus , Pull out feces. Then put your hand into the anus, palm flat, palm down, pressing touch, in the bottom of the pelvic cavity, you can touch a long hard texture of the rod, namely the cervix. Go forward along the cervix and touch a shallow ditch in front of you. Both sides of the groove are curved forward and downward on both sides of the uterine horn. Slightly to the outside along the large curvature of the uterine horn, you can touch the ovaries. Use your fingers to check the shape, size, response of the uterine horn, and the development of the follicles on the ovary to determine the estrus of the cow. The estrus cow's cervix is ​​slightly larger and softer. Due to uterine mucosal edema, the uterine horn volume also increases, the uterine contraction response is more obvious, and the uterine horn is firm. On both sides of the uterine horn, two ovaries can be felt. The follicle developed on the ovary protrudes from the surface of the ovary and is smooth and slightly fluctuates when touched. The maximum diameter when developing is 1.8-2.5 cm, and there is a touch before the ovulation. In non-estrus cows, the cervix is ​​thin and hard, the uterus is relaxed, the touch is not so obvious, and the contraction response is poor. The ovaries of adult cows are larger than those of cattle (because many estruss, many degenerative corpus luteums still exist), the surface of the ovary has small protrusions, and the texture sells. It is worth noting that when touching in the rectum, it should be done with a finger and it should not be scratched with fingers so as not to damage the rectal mucosa. In the cow's responsibility (defecation movements) or bowel contraction can not push the arm hard in, can wait for it to blame or shrink to stop checking. Cows with normal estrus can use external observations to accurately identify estrus. It is not necessary to use rectal examinations. In particular, unskilled technicians can easily break the follicles through rectal examination and affect bovine pregnancies. Although the estrus performance of cows has a certain regularity, but due to the influence of internal and external factors, sometimes the performance is not obvious or regularity, so when determining the appropriate period of insemination, we must make a comprehensive judgment, specific analysis.
