Preventive measures for diarrhea include feeding colostrum and creating good sanitary conditions. It is best to use Laifuxing within 6-12 hours after calves are born. Beneficiaries can quickly occupy a place, inhibit bacteria, regulate intestinal health of calves by means of bacteria sterilization, prevent diarrhea and reduce the incidence of pneumonia.
First born 0~6 months old calves for calves. This period of mismanagement, poor care, high mortality. According to incomplete statistics, the mortality rate is about 15%, or even higher. Because calves are not well developed. The organs are not yet mature. Not adapted to the external environment, weak resistance. It is easy to cause digestive tract diseases, respiratory diseases. All kinds of diseases caused by the invasion of calves by pathogenic bacteria are very easy to cause death and cause great losses to the dairy industry.
Improper management of prenatal feeding of cows
Weak cattle prenatal feeding management is not in place will lead to the congenital deficiency of calves. In terms of feeding, it is mainly due to the unscientific structure of the pregnant cow's diet, improper proportion of coarse and fine, lack or insufficient nutrients, which will not only lead to poor health of the cow, but also easily lead to dystocia, postpartum paralysis and insufficient lactation of the cow, which will make the calves unable to eat enough milk, resulting in the death of the calves, which will also lead to the growth and development of the calves in the embryonic stage, increased mortality of calves.
In terms of management, it mainly refers to the lack of exercise of pregnant cows, poor physique, prone to dystocia, and pregnant cows.
In daily management, crowding and fighting are not paid attention to, which is prone to premature delivery or miscarriage, resulting in death of calves. In addition, if the cow's physique is weak and its production performance is poor, such as old, weak, sick and residual cattle, its reproductive performance and lactation performance are poor, and it is easy to have no milk after delivery and stillbirth, weak fetus, premature delivery and abortion. Even if it can successfully give birth, the calf's physique is weak and the survival rate is low.
Cow Dystocia
Dystocia in cows is the main cause of death of calves. When dystocia occurs in cows, the fetus stays in the uterus and cannot be discharged. If artificial delivery or improper midwifery occurs, calves will suffer from hypoxia or inhalation of amniotic fluid and suffocation, foreign body pneumonia and other diseases will occur. Some will also suffer from limb strain and dislocation during midwifery, thus causing calves to die.
Improper care of calves
Calves leave the mother after birth and enter a new environment. Because the development of various functions is not perfect, if they are not properly cared after birth, they are susceptible to a variety of diseases, such as pneumonia, omphalitis, diarrhea, constipation, etc. These will lead to the death of the calves. Although there are individual calves can be treated, but the physique is also weak, easy to be eliminated in the later period due to poor growth and development. In addition, if you do not pay attention to the daily care of calves, prone to freeze to death, stuck dead. This is mainly due to the weak sense of responsibility of the staff and the weak physique of the calves.
Improper management of calves
Newborn calves have the characteristics of fast growth and development, vigorous metabolism, and with the increase of age, weight also increases, the demand for nutrients also gradually increases, if the cow's milk secretion is insufficient, the lack of nutrition in feed will lead to malnutrition of calves, affect the growth and development of calves, make their growth slow, or even stagnation, poor physical fitness, poor adaptation to the external environment, if the environment changes slightly will cause the calf disease, will eventually cause the death of calves. When feeding calves too casually, will cause calves digestive system disease, easy to lead to death of calves. In the process of calf management, if the feeding environment is poor and the disinfection is not in place, it is very easy to make the calf sick and cause the death of the calf.
To provide adequate and appropriate nutrients to improve the body of the cow, improve the reproductive performance of the cow, the nutrition in the diet should be comprehensive, reasonable ratio, in addition to meet their own needs, but also to meet the growth and development of the fetus, and postpartum lactation. Therefore, it is necessary to scientifically and reasonably prepare the cow's diet and provide different nutritional levels according to the different physiological stages of the cow. Pay attention to the quality of cow feed, it is strictly prohibited to feed cows mildew, contaminated feed, otherwise it will have a toxic effect on the embryo and lead to abortion, premature delivery and so on. To strengthen the management of cows, we should ensure that cows have a certain amount of exercise every day to enhance their physique and prevent dystocia. For some old, weak, sick, disabled and low reproductive function cows, they should be eliminated in time.
Scientific midwifery
Before delivery, the staff should make preparations for delivery in advance, maintain the sanitation of the delivery room, provide a quiet environment, and carry out thorough disinfection. Before receiving, the vulva of the cow is washed with o.2% potassium permanganate solution. The midwife should cut the nail short, round and disinfect it. Under normal circumstances, cows should try their best to give birth on their own. The delivery and midwifery personnel should carefully observe the delivery of cows. In case of dystocia, they should give birth in time. Generally, it is regarded as dystocia that 1. 5-2 h after water breaking has not calved. At this time, timely midwifery and scientific midwifery methods should be mastered.Probiotics
DiarrheaPreventive measures, feeding colostrum and creating good sanitary conditions, calves are best used within 6-12 hours after birthCome to FuxingThe beneficial bacteria quickly occupy the space, inhibit bacteria, regulate the intestinal health of calves by bacteria sterilization, prevent diarrhea and reduce the incidence of pneumonia.
Annual Preferential Price
If you don't participate, you really have to wait another year.
Strengthen the nursing work of newborn calves
Calves after birth to quickly clean the mucus in the mouth and nose, to prevent inhalation of lungs caused by asphyxia, and do a good job of newborn calves insulation, and then cut off the umbilicus, cut off the umbilicus should be fully disinfected to prevent infection caused by omphalitis. Newborn calves should eat colostrum within 2h to obtain maternal antibodies as soon as possible and enhance the resistance of calves. For frail calves to special care, artificial auxiliary breastfeeding. Newborn calves should pay attention to iron, in order to improve immunity, increase disease resistance. Strengthen the management of calves. After reaching a certain age, calves should train their ability to feed solid feed, which can promote the development of rumen and provide sufficient nutrition for the rapid growth and development of calves.
Strengthen the management of calves, calves to ensure adequate light and exercise time, can enhance physical fitness, promote metabolism, ensure the healthy growth of calves. Pay attention to the sanitation of the environment and the disinfection of the enclosure to provide appropriate temperature, humidity and air quality. Do a good job of disease prevention, regular deworming, and scientific immunization according to the actual situation of the field, in order to improve the disease resistance of calves.
