First, the observation of the estrus of dairy cows and the grasp of the estrus cycle 1. The cows' reserve cows develop to certain stages (generally between 8 and 12 months of age). The mature mature follicle wall cells secrete estrogen and enter the blood to make the cow's behavior and physiology. Changes occur, called estrus; the first day of estrus is the starting day of the breeding archives of the cattle; 14 months of age have no signs of initial symptoms; they need to make checks, determine the causes, and take measures 2. Each inseminator should master the control The number of estrus cycle days and the estrus rule of an individual cow. Knowing what to do and implementing the breeding of herds as planned. 3. Changes in estrus behaviour of dairy cows: Sensitive and agitation. Looking for other estrus cows. Activity, walking number is more than 5 times that of regular cows. Smells other cow genitals, depending on the chin Cow buttocks and friction press the waist and back subsidence, the tail roots have high appetite loss and milk production declines across the cattle or "stand still" to accept it cattle climb, the latter is an important estrus identification signs 4, the cow body changes The vulva is wet, the vaginal mucous membranes are ruddy, and the vulva is swollen; sometimes the body surface is moist, and the transpiration-like vulva has transparent, linear mucus outflow, or sticks around the vulva, and has a strong stringiness. In the buttocks and tail roots, small bruises or bald patches caused by over 60% of the estrous cows that have undergone the climb can be seen as vaginal bleeding, which occurs approximately two days after heat. This sign can help determine missed estrus and provide the basis for tracking the next estrus date or adjusting the estrus time. 5. Observe that most cows’ estrus lasts from 10 to 24 hours (1812 hours). 0:00—6;00 43% 6:00—12:00 22% 12;00—18;00 10% 18:00—24:00 25% Naked estrus observation is currently the most practical method for abnormalities Oestrus, cows that have not been exposed to heat for 50 days postpartum should be promptly inspected and take measures to return to normal estrus. 6, timely infusions standing still, accepting cross-climbing, and vomiting out of the occult with strong silky mucus Up to 6-8 times, two-finger level drawing can be “y†strong, it is a gradual process that is the sign of the entire estrus in the optimal period of insemination. The duration of estrus has individual differences. Observed static standing, strong drawing mucus signs, insemination, is the best opportunity to master the timing of insemination can be timely. Only when the contact follicle diagnosis delays ovulation, the second insemination is required to have a good grasp of the technique of estrus at the same time, and the breeding plan can be implemented more effectively, the estrus cycle can be shortened to make up for the losses caused by missing cattle, and the artificial insemination intensification becomes Possible Second, artificial insemination operation specification 1. Rectum examination of the uterus and ovaries (bubble) situation and grasp the cervix insemination is a standard artificial insemination technology 2. Touch the follicle mature state, in the soon after ovulation or just ovulation insemination, will Obtain a high fertility rate 3. Preservation and insemination should maintain cleanliness around the bull's pus and dryness and hygiene of insemination equipment (film protective sleeve should be used outside the insemination gun) 4. Uterine wound bleeding on sperm and fertilized eggs The survival is unfavorable and trauma should be avoided as much as possible. It can be used as a lubricant that does not harm sperm and is not irritating to the genital tract. 5. The correct method is to hold the uterine cervix to the vagina and bring it close to the front of the anaesthesia. Instead of pushing the spermatophore to the cervix. It is necessary to put the insemination device into the cervix with the feeling of the fingers. 6. The technique of inseminating the front end of the insemination device when it passes through the cervix and irregularly arranging the pleats is a key technique for insemination. Can be used to change the forward direction of the insemination, withdrawal, swing, rolling and other operating skills, so that the front end of the insemination device through the cervix. It is forbidden to go into the rectum 7 to recuperate the essentials and procedure of cervical insemination. The arm is coated with lubricant and gently touches the anus so that when the anus muscle relaxes and enters the rectum, it should be avoided and the rectum should be avoided. Move in the opposite direction. Gradually excrete feces to prevent air from entering the rectum and cause rectal swelling. Insert your fingers into the side of the cervix, extend into the lower part of the cervix, and then grasp the cervical cervix with food, middle and thumb grip. The cervix is ​​firmer, the vaginal texture is soft, and the body is like a sponge. Body (feeling elastic after touch) The inseminator enters the separate vestibular vestibular segment at an angle of 35-45 degrees, and enters the cervix segment slightly forward and downward to grasp the entire gesture of the cervix to be softened before the introducer enters the cervix The cervix can be leaned against the edge of the pelvis, and gently squeeze the vaginal wall around the cervix, so that the insemination device can only enter the cervix, without straying into the vagina, the implantation site of the semen is the uterus and uterine horn combination. After injecting semen after confirming that the injection site is correct, under skilled conditions, the semen can be injected into the ovary side of the uterine horn and non-disposable insemination equipment, after each cattle insemination, after cleaning, drying and disinfection, reserve 8, semen Quality, access quality: Vitality ≥ 0.35, linear sperm density ≥ 10 million, acrosome integrity rate ≥ 40%, abnormal sperm rate ≤ 20%, number of non-pathogenic bacteria ≤ 1000/ml Storage: semen stored in High-vacuum insulation liquid nitrogen tank; liquid nitrogen tank should be placed on a clean, dry, ventilated wooden pad; liquid nitrogen level should be maintained at 18cm or more, to 16cm, that should add liquid nitrogen, can be used red and blue The ammunition indicating pipe or fixed pound weighing discriminating the liquid nitrogen level semen removal: Except for the frozen essence that needs to be removed this time, other frozen essences can not be mentioned above the tank mouth below the 3.5cm line, looking for frozen essence more than 10 seconds, should Put the dispensing drum back into liquid nitrogen, and then lift it up to keep the coolness of the frozen essence; take out the 38°C water bath immediately after thaw or other effective thaw method; each bull's semen should be placed in the same subpackage Inside the barrel, there is a separate The list includes the bull number, quantity, and access record. When cleaning the liquid nitrogen tank, the prepared clean liquid nitrogen tank should be placed side by side and transferred quickly. The time for the frozen essence to be exposed outside the tank can not exceed 3 to 5 seconds. Third, the tire test: The correct early diagnosis can reduce feed loss, determine the gestation period, calculate the expected date of birth and arrange the dry period; test the fetus has two methods of rectal examination and hormone test, usually only with rectal examination; 21-24 after insemination Days, touch the 2.5-3cm full-developed corpus luteum, indicating that 90% to be pregnant; 60 days after insemination, the first 180-210 days to carry out two tests, the first is to confirm the presence of a child, the second is to ensure that The fetus, ready for dry milk, the first time of the test on the premise of technical assurance, can be advanced to the 40-60 days after insemination for several major indications of pregnancy when the test: 21- 24 days 40 days 60 days 90 days 180 days 210 days Ovary 2.5-3.0cm in diameter, well-developed corpus luteum uterine horn angle asymmetry; fluctuating sense of pregnancy angle; uterine angle diameter 4-6cm gestational angle diameter 6-9cm; gestational angle fetal fluid movement, embryo Rebound, sensible gestational diameter 12-16cm; may touch along the Palace To the embryo and the small cotyledon; The uterus sinks into the pelvic cavity The uterus sinks in the abdominal cavity Start to ascend the wide ligament The diameter of the middle uterine artery 0.4-0.6cm Same as the left middle artery 0.5-0.7cm in diameter; There is a sense of middle artery tremor 0.7-0.9cm; Pause feeling Middle artery 0.8-1.0cm; Flowing water IV. Breeding plan: Feeding and management of reserve cattle is one of the keys to improving the conception rate, yield, and life-long milk production; when 15 months old Holstein cows weigh up to 375kg, they can join Breeding, 18 months of age is the upper limit of the input breeding age; the production interval is divided into different production levels of dairy cows (an average of 12-13 months); to avoid the most hot seven, in terms of the dairy farm's own benefits and management difficulties. Eight or two months of childbirth, one can increase the output of 305 days, the second is to reduce obstetric diseases; April-June should arrange more cattle to deliver, in order to increase the amount of raw milk listed in June-September five, reproductive barriers 1. The cause of endometriosis, in breeding practice, is mostly due to poor handling or uterine contractions during or after calving, resulting in retention of lochia, bacterial mass production 2. Cows born after the release of the placenta, from the uterine epithelial cells Debris, Secretion fluid, blood, white blood cells and fat mixture is referred Elu. Healthy cows with good health, clean environment, strong uterine contractions, and normal estrogen secretion (enriched endometrium, increased white blood cell activity, and “self-purificationâ€) generally become sterilized in the uterus after 20 days. The occurrence of endometritis in other properties and colors of lochia reveals the occurrence of endometritis. 4. The presence of endometritis must be vigilant if there is no lochia or mastitis within 10 days after birth. 5. Purify the uterus with antibacterial agents. Systemic medication is available. 6. Various stages of the cow's estrous cycle have various physical and behavioral changes that are expressed during some of the hormone activity processes. 7. Reproductive hormones are secreted by the hypothalamus, pituitary, ovaries, and uterus, respectively. And the role of recycling, so that the reproductive cycle of dairy cows to achieve. However, reproductive disorders occur when any one of reproductive hormones is abnormal or unbalanced. When reproductive disorders due to hormone imbalances occur, the choice of the relevant drugs, reproductive records, and the success or failure of the breeding of dairy cows in archives is determined by the effectiveness of on-the-spot observations several times per day. Observing the estrus, passions, and Abnormal behavior, uterine (vaginal) secretions status, collection of breeding, fetal examination, miscarriage and other information recorded on the portable mini-notebook, followed by computer or file card or disposal procedures, is also one of the artificial insemination work specification 1. Daily notebook contents should be categorized into estrus, breeding and reproductive barriers, etc. 2. Each cow should be established after the puberty period (reproduction card) 3. Propagation card content: Cow Number, location, housekeeping, date of birth, parent number, parent number, estrus date, breeding date with bull, test results (produced date), retest results, childbirth or abortion, date of premature delivery, difficult/successful delivery, The contents of breeding cards such as calf number and major reproductive impairment records should be filled out on the fixed date of the current month

Infrared light is part of the sun`s invisible spectrum. We can feel this type of light, which we perceive as heat. sun produces most of its energy output in the infrared segment of the spectrum. Our atmosphere has a [window" in which it filters infrared rays ranging between 4 to 14 microns to safely reach the earth`s surface.
FIR therapy has been used for over thirty years to treat patients with various health problems and have exhibited positive results. These conditions include but are not limited to: TMJ, arthritis, high blood pressure, benign prostrate hypertrophy, high cholesterol, pain, hemorrhoids, cystitis, gastritis, asthma and bronchitis, sore throat, muscle tension, muscle spasms, adhesions on cold hands and feet, poor skin tone, acne, body odor, eczema and psoriasis. Studies have shown that the patients have displayed minimal to almost no side effects and produced various positive results. It does so by reducing the sensitivity of the neural pathways of the nervous system, triggering the body to release endorphins.
In traditional Eastern medicine, the jade is believed to possess healing qualities by emitting a gentle steady energy that strengthens the lungs, heart, thymus, immune nervous system, as well as increasing kidney filtration and blood detoxification. The jade is a natural transmitter of far-infrared rays in the same wavelength as from the human body. It contains vital elements essentials for the human body such as calcium and magnesium. The jade also produces negative ions which encourage the cells metabolism, which in turn increases one's vitality, strengthens one's immune defense and enhances endurance. Slow down the process of aging as well as maximizing the body's ability to strengthen its natural defenses and healing abilities.
The health benefits of jade lower high blood pressure and high cholesterol levels as well as improves poor circulation. It also increases in sperm count and regenerative functions.
