In order to ensure the normal shape and posture of the cow's limb hoof, it is generally necessary to repair the hoof preventively, and there are two ideas for the repair time point. One is to carry out hoof shape correction before the body mass increases sharply to ensure normal production in the later period, I .e. hoof shape renovation starts 120 days after delivery for newly dried cows. The second is to carry out seasonal hoof trimming in the spring and autumn period of each year. At this stage, hoof cutin grows fast and can recover quickly after trimming. However, no matter which mode of repair is used, the hoof shall not be overrepaired to prevent damage to the bottom of the hoof.
Cow limb and hoof disease is generally not fatal after the onset of disease, but the actual livestock production is sharply reduced. To reduce this disease, attention should be paid to limb and hoof health care. Today, Xiaobian shared three measures to effectively prevent the occurrence of limb and hoof diseases in dairy cows:
1. nutrition management
Dairy cow nutrition management is reducing.limb and hoof disease of dairy cowplay an important role, such as rumen acidosis is one of the main causes of laminitis. It is important to note that the content of non-structural carbohydrates is recommended not to exceed45%And the fiber content in the diet should be sufficient. According to experience, the composition of the general forage should account for the dry matter intake of lactating cows.1/3above, such as the useTMRThe diet needs to pay attention to mixing evenly,TMRSieve to check that the proportion of each layer is appropriate and the diet is stable. In addition, trace elements and vitamins are also very important for hoof health. Zinc is necessary for cutin growth, and the recommend dosage is40Milligrams/kg, it is in the liver with vitaminsAThe latter plays an important role in maintaining epithelial tissue and cell replication. Copper deficiency or excessive intake of molybdenum will cause an increase in lame cattle, visible cow joints become larger and other phenomena, copper recommend dosage is greater.10Milligrams/Kilograms.
Under the condition of high temperature and high humidity in summer, the fed feed is easy to ferment and generate heat, so the feed is prepared before feeding, and the feed shall not be prepared several hours in advance to prevent limb and hoof diseases induced by corrupt feed, and the trough shall be cleaned in time before feeding to ensure the cleanness of the trough, and the trough shall be disinfected if necessary.
2. seed selection and breeding
While selecting high-performance bulls, functional indicators such as limb and hoof traits should also be considered to help the herd improve limb and hoof from germplasm and reduce the occurrence of limb and hoof diseases. Environmental Management
Health. With the advent of summer, the moisture and humidity increase, especially the need to clean up the feces in time, through the proportion of limb and hoof health assessment score to evaluate the advantages and disadvantages of the cow's limb and hoof environment. When the manure exceeds the crown of the hoof, it affects the health of the cow's hoof,3More10%At the same time, environmental rectification measures must be made to improve the hygiene of limbs and hooves.
Anti-skid: It is also easy to cause slippery cement ground when wet. When cows often slip or there are more injuries on the outer side of the hoof, the ground should be polished and anti-skid in time to reduce the risk of falling and rational damage to the hoof substrate.
Drying: While cleaning up the road surface and cowshed, it should be ventilated as much as possible and disinfected regularly to ensure the dryness of cattle activity places such as cowbed, cowshed, passage and hall to be crowded, so as to reduce the breeding of bacteria.
3. nursing
hoof bath
effectivehoof bathIt can prevent hoof fork inflammation and reduce the occurrence of infectious hoof diseases, but hoof bath management is very important. It must meet certain conditions to maximize the effect of hoof bath.
preventive nursing
In order to ensure the normal shape and posture of the cow's limb hoof, it is generally necessary to repair the hoof preventively, and there are two ideas for the repair time point. The first is to correct the hoof shape before the sharp increase in body mass to ensure normal production in the later period, I .e., newly dried cows and postpartum cows.120The second is to carry out seasonal hoof repair in the spring and autumn period of each year. The cutin of the hoof grows fast at this stage and can recover quickly after repair. However, no matter which mode of repair is used, the hoof shall not be overrepaired to prevent damage to the bottom of the hoof.
