Lodge licking brick magnesium element-prevention of heat stress, magnesium is an effective activator in the rumen of dairy cows, can maintain the normal rumen flora, protect the health of the rumen, participate in the joint action of nerve regulation and calcium and phosphorus, promote rumen peristalsis, regulate anion and cation, prevent heat stress, and balance the PH value of the rumen.
TimerSpermatosisTechnology can improve the pregnancy rate and breeding efficiency of dairy cows, but the insemination procedure is not absolute. If the mating results are not satisfactory, the investigation should be carried out at the whole group level. The reproductive performance of cattle dominates everything in the pasture, and in turn, almost everything in the pasture affects the reproductive performance of cattle.
Comply with biorhythms and follow active waiting periods. After calving, the cow's reproductive system does not circulate naturally, and it takes about 40-60 days for uterine involution and normal ovulation ability to resume.
Dystocia and perinatal health will affect the time of returning to normal reproductive function after childbirth. Each herd has its own ideal active waiting period, but the active waiting period of the high-yielding herd is slightly longer, increasing to no less than 60 days or 70-80 days, which often means that the cow will have a better reproductive ability of the uterus environment.
The active waiting period of the herd should be based on the level of perinatal feeding management, pregnancy rate, the number of days to reach the peak milk production, avoiding high negative energy balance, lactation curve and target dry milk lactation. Most pasture management software can calculate the conception rate of dairy cows based on the number of lactation days. These data can help us to accurately find the first mating time range that makes the cow first mating pregnancy rate the highest.
Try to avoid situations that cause cows to not ovulate, such as body condition score (BCS) is too low.
High milk production in newly produced cattle usually means a balance between weight loss and body fat mobilization. A cow has a negative energy balance when it loses more energy in the form of milk or undigested food than it ingests. Hiring a nutritionist for a reasonable combination of dietary nutrition can shorten the duration of negative energy balance and maintain a normal cycle.
An established nutritional strategy begins before calving. Dry cows and first-born cows that were too obese had greater post-partum weight loss. Therefore, the negative nutritional balance of these cows after delivery will be more serious than that of individuals with ideal prenatal condition. High levels of weight loss in the short term can lead to disturbed reproductive cycles and lower conception rates in cows.
If your timed inseminations work poorly in first-born cows, you should start scoring the heifers from their youth. Body condition score is an important indicator to judge whether young cattle are still growing.

In warm climates, when cows do not exhibit estrus behavior due to decreased estrogen levels, estrus synchronization can help. However, timed insemination does not solve the problem of low oocyte quality and embryonic death caused by heat stress several days after conception.
The cattle farms with the best breeding conditions are usually equipped with the best heatstroke prevention and cooling systems. Cows with less heat stress have healthier follicles, which can better maintain pregnancy and shorten the empty pregnancy period.
Don't neglect the implementation of heatstroke prevention and cooling on dry cows. The more comfortable the dry period, the smoother the calving will be. Improving the perinatal period is equivalent to increasing the overall conception rate of the herd, which will eventually increase the production level throughout the lactation period.
Lodge Lick Brick Magnesium Element--Prevention of heat stressMagnesium is an effective activator in the rumen of dairy cows, which can maintain normal rumen flora, protect rumen health, participate in nerve regulation and calcium and phosphorus together, promote rumen peristalsis, regulate yin and yang ions, prevent heat stress, balance rumenPH value.
When timed insemination does not produce the desired results, the normative nature of insemination is the easiest to consider; of course, it should be. Careless employees are not accurate in many aspects, and the resulting losses are very costly. However, especially if the same person performs weekly insemination, other normative aspects need to be considered.
There may be regulatory issues in the management of each cow if the cows do not often go through the neck clips because of broken neck clips or overcrowding of the barn.
Large-scale groups put more pressure on the mating technician, which may lead to improper semen processing. A thin tube of frozen semen, sensitive to light, temperature and thawing procedures, can have been deactivated during the chaotic mating process.
A thawing container should not defrost more than 5 1/4 cc or 3 1/2 cc thin tubes at a time. Too much thawing can lead to improper thawing. If the technician works alone, the efficiency of breeding should depend on the amount of frozen semen that can be thawed at a time. If necessary, two or more thawing containers may be used simultaneously.
When a technician is breeding a large herd of cows, it can be exhausting, which can affect the quality of the work. For example, when moving too fast or inattentive, semen will be placed incorrectly. When technicians are under pressure to move quickly, they can carry more than one gun at a time.
Employees who are not properly trained can have a negative impact. Some basic tasks may not be done well, such as confusing semen with the vas deferens or placing semen in the wrong position of the vas deferens.
Sometimes the most obvious solutions are the most difficult to find. Are your technicians professionally trained?
