Cattle Breeding Techniques: Six Issues Needing Attention in Newborn Yak Care
In the process of raising cattle, many people will encounter these problems. The survival rate of yak is low, the growth rate is slow, and the ratio of meat to meat is high.
The technical level of raising cattle directly determines the efficiency of the cattle farm. For the breeding cattle farm, the key to improving the efficiency lies in the fact that the birth is much more, the death is less, and the growth is faster. At present, the average annual production of yak in most cattle farms in China is about 0.8, but the survival rate of yak is low, the growth rate is slow, and the ratio of feed to meat is high. However, the cost of cattle is high and it is losing money in successive years. . It has been proved by production practice that strengthening the care of newborn calves can help improve the survival rate and growth rate of calves and reduce the ratio of feed to meat during the fattening period.
1. The newborn yak is weak.
Weaknesses are bound to have high mortality, high incidence and slow growth. The key to the physical strength of newborn calves is the birth weight and vitality. During the cow pregnancy, especially late in pregnancy calf rapid development period, be sure to add enough nutrients to promote the development of calves, to achieve the desired birth weight and vitality, while also prompting cows produce more milk. According to the mating time budget, the delivery time should be done, and the cows should be harvested to avoid excessive labor or dystocia. When the umbilical cord connected with the cow and the cow breaks and does not produce for a long time, there will be hypoxia or poor vitality. The problem, and then the formation of weakness.
2, to prevent calves from suffering cold
After the calf is born, the amniotic fluid in the nose and mouth should be removed in time to prevent the amniotic fluid from entering the lungs and causing foreign body pneumonia, or the amniotic fluid can be eaten into the stomach and affect the digestion ability. The body of the amniotic fluid that allows cows to lick dry, which helps promote the afterbirth discharge and promote feelings of mother and child, in the case if the cow does not lick or cold weather, etc., can be manually or using a towel to dry wheat bran. In addition, the first 8 to 12 hours after the calf is born, it is necessary to do the insulation work, it is best to make the temperature reach 20 ° C or above (the closer to the cow body temperature is better), otherwise it is prone to cold diarrhea, disease or vitality decline.
3, scientifically cut the umbilical
Many breeders will be carried out immediately after birth calves off the umbilical cord, in fact, this practice is not good. The yak is broken 5 to 10 minutes after birth, which can effectively alleviate the hypoxia state of the yak, and it is of great help to improve the yak body and vitality. Secondly, the umbilical cord blood contains a large number of hematopoietic stem cells. Late physical fitness, immunity, and growth rate are critical, and cord blood loss should be minimized. Before the yak breaks the umbilicus, the cord blood is squeezed back, then disconnected from 3 to 5 cm, and the umbilical cord and the surrounding area are disinfected with iodophor (for at least 3 to 5 days). In addition, the umbilical cord should be ligated as much as possible. Let the wound open and dry naturally and fall off.
4, eat colostrum as soon as possible
After birth calves should be allowed to eat as soon as possible and eat enough colostrum to get nutrition and maternal antibodies in breast milk. When the calf colostrum can not eat on their own, should be artificially assisted feeding for some calves do not know, the milk may be allowed pushed finger into the mouth sucking calves, they can slowly form a conditioned reflex normal Eat milk. Three days after the birth of the yak, the breeder must carefully observe the yak feeding situation and the quality of the mother milk water. When cows have insufficient milk production, they should increase nutrition and lactation, or send samples or artificial breastfeeding to yak; when cows suffer from mastitis, they should stop breastfeeding yak, so that yak eats bad milk and diarrhea occurs.
5, to prevent yaks from eating dirt
The occurrence of diarrhea in newborn calves is related to the amount of milk and temperature, on the other hand, it is related to eating pathogenic microorganisms. The former causes dyspepsia and diarrhea. The latter may cause bacterial or viral diarrhea, so it should be prevented as much as possible. The yak eats dirt. The cows are disinfected after the birth, and the breasts are disinfected to prevent the yak from eating pathogenic microorganisms when they are born. The environmental sanitation and disinfection work is done to reduce the pathogenic microorganisms in the environment.
6, to avoid stepping or crushing
In the actual cattle raising process, a considerable part of the yak was trampled or crushed, so that the breeder could not afford to feel sorry. To avoid calf being crushed or crushed, you can start from the following points: choose the cows with better maternality as much as possible, and do the health care before and after the cows to promote postpartum recovery; strengthen the control of the temperature of the delivery room. When the temperature is too low, the cows will get together to warm up, and the yak will be nestled around the cows, so the chance of stepping on or crushing will increase greatly; as far as possible, a cow and a delivery room (or a bar) will avoid The calving cows are put into large groups for breeding; the frightening of the cattle is reduced; the breeder conducts more rounds of the tour, and the delivery room is as close as possible to the people for 24 hours.
