How many teeth do cows have?


Information about whether a cow has teeth, as well as the specifics of their growth will help to properly care for cattle, avoid problems with the health of the animal and improve farm performance. The anatomical structure of the bore of the jaw has its own specifics - the upper teeth are quickly erased and form a solid bone plate. An adult individual constantly chews the cud, the digestive system is rather complicated and requires attention from the owners at each stage of development.

The structure of the jaw in cattle

Each species of a living creature has a special structure of the oral cavity - this is directly related to the type, specificity and needs of the animal. Cow teeth are an important organ of the digestive tract, along with cheeks, lips, palate and tongue.

In the process of evolution in adult individuals, the lower incisors remained, but the upper teeth "disappeared". Food and grass is captured with tongue and lips. The so-called "millstones" fray the contents of the mouth. The lower part of the mouth has a special lateral mobility. If you compare, for example, with a cat, then it cannot move its jaw at all - that is why it constantly turns its head in the process of eating.

The newborn calf has only four milk teeth. Somewhere in a week 4 incisors grow, and within 7 days - 2 root ones.

In the half-year-old individual, the remaining molars erupt, and by two years the jaw is already fully formed. Toothache does not threaten the calf, since the process of eruption and replacement of the dairy bone processes is absolutely painless. But sometimes it can be difficult, and the animal will need your help.

Changes in the upper jaw of cattle

Gradually, the upper incisors of young individuals change to a dental bone pad, this occurs at the age of 2.5 years. Signs of bison (as this process is called) include:

  • strong saliva secretion;
  • reduced yields;
  • loosening and falling out of incisors;
  • ignoring solid foods;
  • decreased activity and appetite;
  • possible temperature rise.

At this time, you need to carefully observe the animal and provide him with good nutrition, enriched with vitamin D and calcium.

The lower jaw of the cattle can move in a circle, on the upper gum roller is located - the incisors cut the grass, and the molars chop the food.

Features of the structure of incisors and cattle molars

The cow on the lower jaw has eight short-crown incisor teeth, there are none on the upper jaw. The gingival cushion is covered with keratinizing epithelium, which allows cows to easily grind grass.

The incisors of cattle consist of the following parts: crown in the form of a scapula; the neck is on the edge of the gum; the root is covered with bone tissue of a dark color.

In the oral cavity of adult animals, there are 24 indigenous follicular bone processes. The teeth of the cow (molars and pre-molars) are long-crown and have such features:

  • the crown is covered with gray cement;
  • there is no neck;
  • root is very short.

The structure of the jaws of a cow does not allow her to quickly chew on food with her teeth. First, she quickly fills her big stomach with grass, then belches it and chews it twice.

Those who didn’t know how many teeth a cow has will be more knowledgeable now. The young individual has 20, and the adult - 32.


Signs of fluorosis in cattle

Briefly focus on the disease of incisors in cattle. The disease affects animals between the ages of 9 and 12 years. The symptoms of fluorosis are most pronounced: diffuse pigmentation (the appearance of brown or yellow spots); lateral shakiness of teeth; the occurrence of chips on the enamel, the destruction of its structure.

Endemic fluorosis in cattle is associated with a high content of fluorine in water and mineral supplements. Sick animals lose their fatness, reduce milk yield. Breeders should be attentive to the health of all livestock, as the profitability of production directly depends on this.

And many processes in the body depend on the quality of the teeth of the cow. How well the food will be ground, milk will be more qualitative and more useful, and the weight gain of the meat breed will also be quick.

Focus on factors that promote good cow digestion

It is worth paying special attention to the places where cattle grazing occurs. Since cattle actively absorb grass and hay, walking should be done where lush and lush vegetation grows. For the winter, it is worthwhile to procure a sufficient amount of hay, as well as take care of additional additives (especially for vitamin D, which helps to strengthen the dental and bone structure of the animal).

It is very important that the teeth of cows, like those of rodents, are constantly growing: as the abrasion progresses, the length of the shoots is corrected. Therefore, the animal will definitely not be left without an important digestive organ, which is very peculiar to man.

"Hemp" in the oral cavity will indicate the advanced age of the animal, when the growth of teeth is significantly slowed down.
