Issues for Attention in Dairy Cow Breeding

It is an extremely important part of cattle production to raise good cows, breed yaks, and produce more milk. The breeding of dairy cows is the basis of breeding, and raising the conception rate is the key to reproduction. Therefore, in order to raise dairy cows effectively and improve economic efficiency, we must pay attention to the following aspects: 1. Feeding and management should be reasonable In order to ensure the normal breeding of cows, in terms of feeding and management, cows must meet protein, vitamins, calcium, phosphorus, etc. Mineral needs. Diversification of feed types, winter and spring green and juicy feed and quality hay must be guaranteed to meet the supply, and timely supply of a certain amount of salt, bone meal and enough clean warm water to prevent malnutrition during calves. After the yak is born, sufficient fresh milk should be given so as not to hinder the growth and development of calves and affect the normal development of reproductive organs. Long-term nutritional deficiencies in bred cows can delay the puberty and affect pregnancy. Before cows are exposed to lochia after delivery, they should not be given more concentrates so as not to affect the recovery of reproductive organs and normal estrus after birth. Exercise and sunbathing play an important role in strengthening the development of cows at various stages and improving the reproductive performance of cows. The cowshed needs to be cool in winter and cool in summer, with air circulation and good drainage to ensure the health of cattle. 2. Young cows must be age-matched to correctly grasp the initial age of the cows. Not only can they exert individual production performance and reproductive ability, but they also have an important role in improving the quality of future generations of cows. Generally, the cow is assigned to be 16-18 months old and weighs 350 kg. The premature mating of cows not only affects their own growth and development, but also the calves born are of small birth weight and are of weak constitution and are prone to dystocia. 3, understand the law of estrus, grasp the timing of breeding accurately grasp the objective law of cow estrus, timely breeding, is the key to improving the conception rate. "If you want to match, the heat must be stable." Accurately grasping the timing of breeding has an important role in improving the conception rate. 45 to 60 days postpartum, the first estrus begins. The estrus interval is usually 18 to 21 days. The estrus usually occurs before noon. When the estrus occurs, the cow's pus is swollen, soft and lax. The labial mucosa is congested, the flush is shiny, and the pus Flow out of mucus. The mucus that initially flowed out is a clear, transparent sample that can be pulled into filaments, then gradually whiter and thicken over time, with a tendency to pull off, sometimes with a small amount of blood sample secreted out. Cows are more irritated than usual, and squeaky, unquiet, willing to approach other cows or bulls and take the initiative to climb. Sometimes accompanied by urine or short-term phlegm. Loss of appetite during heat, milk production decreased significantly. Young cows are more sexually excited than older cows. However, they must observe different observations. Based on external observations, technicians should also be asked to do further inspections. In general, the experience of “climb and run, mating prematurely”, “climb and twist, deliver and control” and “older and younger, less late and strong” are worth learning from. 4, do a good job of cold matching, to avoid indiscriminate allocation in order to improve the utilization rate of excellent bulls, speed up and expand the transmission speed and scope of good genetic traits, and resolutely avoid chaos. For bulls that are not suitable for breeding purposes, they should be cast off or managed separately to prevent unlawful matches and close relatives from mating. When using frozen semen, attention should be paid to the species, name, and lot number of the bull. Record the motility of the sperm after thawing should not be less than 0.3, and the number of spermatozoa containing linear motion per tube or tube should not be less than 1,500. 5, to find out the causes of empty space in a timely manner, and strive to eliminate the hollow cause cows are empty for many reasons, mainly congenital and acquired two aspects, congenital infertility is generally an abnormal cow reproductive organs, cervical position is not correct, cervical atresia, vaginal stenosis , Hermaphroditism, infantile disease, heterosexual females, etc., should be eliminated early. Acquired infertility is mainly caused by human factors. In many cases, it is caused by improper feeding management and genital disease. Such as swept odd milk, technicians do not follow the operating procedures insemination, insemination equipment and cow genital disinfection is not strict, endometritis, vaginitis. For the cows suffering from diseases, we must pay close attention to treatment, timely improve the level of feeding and management, and reduce economic losses. 6, do early pregnancy and fetal cows 40 to 60 days after mating is not in heat, through direct inspection can be determined to have been pregnant. In order to prevent early embryonic death and miscarriage, it is necessary to strengthen the feeding and management and supplement the trace elements, such as iodine, selenium, copper, cobalt, manganese, calcium and phosphorus in the salt. At the same time, injectable drugs are used to protect the fetus, and progesterone 150 mg or sodium selenite vitamin e 20-30 ml is injected 2 months after pregnancy.
