Phosphorus rich rocky lick brick significant efficacy: 1: Solve the problem of maternal reproduction (for example, long interbirth time, repeated mating infertility, frequent abortion) 2: extend the peak period of lactation; improve milk production. 3: Extend the life of the mother; (an 8,000-litre cow loses 60kg of minerals in its milk) 4: Improve the comprehensive health index of dairy cows and reduce the incidence of dairy cows (e. g. mastitis, hoof disease). 5: Cow pica disappears (gnawing wood, licking hair, licking urine, gnawing plastic) and the fur is smooth. 6: promote food digestion, improve feed utilization, save fine
With the promotion of artificial insemination technology and the large-scale development of dairy farming, efficient reproduction rate has become the key to ensure the lifetime milk yield and economic benefits of dairy cows, and it is also one of the main indicators to determine the service life of dairy cows.
1, reasonable diet
Adhere to the principle of green forage as the main, concentrate as a supplement, and maintain a balanced supply throughout the year, especially to avoid feeding a large amount of concentrate in pursuit of higher milk yield, and no high-quality hay feeding method. The daily diet must be no less4kgThe high quality of green hay, conditional should allow cows to eat freely, and have1/3The length5cmUpper green hay.
2. Nutritional balance
Too high or too low a feeding level will affect the fertility of dairy cows. At present, most farmers fail to purchase refined feed according to the growth and milk production stages of dairy cows, and do not strictly follow the instructions of the "Feed Label". Excessive energy is often caused by excessive addition of corn, while protein and other nutrients are relatively insufficient, which not only affects the health and production performance of dairy cows, but also leads to reproductive dysfunction. Therefore, it should be mixed according to the formula of "feed label" of concentrated feed.3—5The amount of the day, and pay attention to the balance of calcium, phosphorus and other elements and vitamins, in the dry grass season should be supplementedVD,VE.
3. Scientific management
Control the calving interval, one baby a year, to seize the postpartum42The first estrus is about the day, when the conception rate is the highest. Proper exercise can promote the growth and development of dairy cows, maintain strong appetite and metabolic function, and is conducive to the recovery of postpartum reproductive function. It is necessary to change the tethered management mode of most farmers to fence management for free movement. Do a good job in heatstroke prevention and cooling. In hot summer, use sunshade nets, roof watering and other methods to cool down, while keeping cattle barns dry and good hygiene.
4. Estrus Identification
In production practice there are20%There are more recessive estrus in high-yielding cows due to individual differences, and their estrus performance and duration are also different. At the same time, factors such as sudden changes in temperature and continuous rain affect estrus performance. In the second phase of the first16At the beginning of the day, insist on three times a day early, middle and late for continuous observation to improve the estrus detection rate of cows as much as possible.
5, timely inseminate
Through external observation and combined with rectal examination, the development of follicles on the ovary is inferred to infer the duration of estrus and ovulation time.12—18Hourly inseminal conception rate is higher. Farmers should pay attention to the identification of estrus, breeding and pregnancy diagnosis must be the same technician, make records, to ensure high fecundity.
6. Active treatment of reproductive dysfunction
For abnormal estrus, postpartum50Cows that are not in estrus should ask a veterinarian to conduct a systematic examination, confirm the diagnosis of diseases of the uterus, ovaries and other solid organs, treat them in time, and make a good medical history and follow-up examination.
Lodge Lick Brick is imported products. Lodge licking brick production process has reached the international leading level.
Phosphorus-rich Rocky Lick BrickAlso known as"Progestational Rocky", which is specially designed for breeding livestock, especially during the high-yielding period of cows,Phosphorus, calcium, zinc, magnesium, iron, cobalt, iodine, manganese, selenium, sodium, etcmineral trace elementinteractionIt plays a very important role in improving the health index, reproduction rate and milk production of dairy cows, and will affect the final profit and return.
rich phosphorusRocky Lick BrickSignificant efficacy:
1:Solve the problem of maternal reproduction (e. g. long parity, repeated infertility, frequent miscarriages)
2:Extend the peak period of lactation; increase milk yield.
3:Extend the life of the female animal; (A cow with an annual output of 8,000 litres loses 60kg of minerals in its milk)
4: Improve the comprehensive health index of dairy cows and reduce the incidence of dairy cows (e. g. mastitis, hoof disease).
5: Cow pica disappears(gnawing wood, licking hair, licking urine, gnawing plastic), with smooth fur.
6:Promote food digestion, improve feed utilization and save concentrate.
