PLANTS CAUSING MECHANICAL DAMAGE TO TISSUES

Both green parts of plants with sharp spikes and spiky spines, as well as ripened fruits with sharp spikes, spikes and thorns, can cause injuries to animals. They damage the oral cavity, nasopharynx, gastrointestinal tract, as well as eyes, skin, inter-hoof spaces, udders and other organs.

Damage to the tissues is caused by feather grass, triosteum, bristle, moth, etc. However, animal tissues of the feather grass seeds are more often damaged.

Feather grass - Stipa L. Perennial dense bush plant up to 1 m high. Leaves are finely fluffy on top and bare underneath. The fruits of feather grass are grains (Fig. 32). Elongated, hard, have a spiral-shaped awn. It grows in the steppe regions of the European part of Russia. It damages tissues mainly in sheep, goats and horses. This is observed when grazing on feather grass or when feeding feather grass hay with mature seeds with awns.

Toxicodynamics, clinical features and tissue changes. The spiral-shaped awn of the feather grass seeds during chewing break and penetrate into the tissues of the oral cavity. As a result, fistulous passages are formed in the palate, under the tongue, in the masticatory muscles, in the submandibular space. In sheep, they can damage the nasal cavity, advancing into the tissue. In foals, with careless eating of feather grass hay, the spines of the seeds penetrate the respiratory tract, causing aspiration bronchopneumonia. Damage the skin, the inter-experimental gap, greatly irritating the tissue. Developing suppuration in sheep causes lameness, inflammation of the joints. Multiple abscesses also form under the skin. Often there is clouding of the cornea.

Constant anxiety and pain gradually deplete the animals, and they die.
With a large clogging of wool in sheep with feather grasses, the death of animals takes on a massive scale.

Other plants, such as triosticum, have seeds with sharp awns that affect the eyes and the inter-toed space, penetrating into the fur, walls of the chest and abdominal cavities.

Spikelets of green bristles (Fig. 33) are surrounded by green setae with notches that damage the mucous membranes of the oral cavity, salivary glands and tissues.

At the moth (trailer), the seeds are planted with hook-shaped spikes. When feeding oats clogged with such seeds, mechanical damage to the mucous membrane of the digestive tract is observed.

In addition, roofing bonfire, sand roach, prickly nightshade can cause tissue damage.

Treatment. In the presence of awns, bristles in the tissues, the treatment is surgical.

Vetsanekspertiza. Slaughter of animals is carried out without restriction. After stripping, the meat and offal are sent to industrial processing.

Prevention Hay with a feather grass, harvested after fruiting! the latter, it is necessary to pass through a feed chopper or other machines, breaking the grains into small parts. Sheep, especially young animals, should not be allowed to graze in areas with a feather grass after flowering and fruiting. Grass from such areas should be mowed before seed ripening. It is also necessary to carry out an early shearing of sheep, to remove hair around the eyes. Lambs should not be grazed on a feather grass.

PLANTS CAUSING MECHANICAL DAMAGE TO TISSUES

  1. MECHANICAL DAMAGE TO TISSUES
    The consequences of mechanical effects on animals can be wounds, bruises, scratches, abrasions on the skin, bruises, lymphatic extravasation, stretching and tearing of tissues, ruptures of internal organs, abdominal hemorrhages, bone fractures, paralysis, paresis, and shell shock. In animals intended for slaughter, mechanical damages received on farms that occur upon delivery to places are detected
  2. PLANTS CAUSING A PREVIOUS HEART DISEASE (PLANTS CONTAINING HEART GLYCOSIDES)
    Cardiac glycosides are found in various types of digitalis, in adonis, lily of the valley, obvoynik, jaundice, harga and other plants. The glycosides of all these plants have a common chemical structure and have basically the same pharmacological, and in large doses, toxic effects on the heart. Digitalis L. Digitalis genus includes 34 species of plants, 7 of them
  3. . PLANTS CAUSING SYMPTOMS OF SALT EXCHANGE DISORDERS. PLANTS CONTAINING ORGANIC ACIDS AND THEIR SALTS
    Small sorrel (sorrel, sheep sorrel) - Rumex acetosella L. (Fig. 30). A short plant 10–20 cm tall. It has several branching stems. The flowers are small, greenish-reddish. It grows everywhere as a perennial weed, clogging fields, meadows, steppes, found among shrubs. Large sorrel - Rumex acetosa L. A plant 30-60 cm high. At the end of a straight furrowed stem
  4. PLANTS CAUSING THE PREVENTION OF RESPONSE TO THE RESPIRATORY AND DIGESTIVE TRACT (PLANTS CONTAINING THIOGLYCOSIDES)
    Glycosides are called ether-like organic compounds that readily break down into the carbohydrate part (glycon) and one or more other substances called aglycones, or genins (non-sugar part). After absorption in the gastrointestinal tract, they also break down into glycon and aglycon. Glycosides are unstable and quickly disintegrate when they are isolated from plants, as well as during
  5. PLANTS CAUSING PREVENTLY DAMAGE TO THE GASTROINTESTINAL TRACT AND SIMULTANEOUSLY ACTING ON THE CENTRAL NERVOUS SYSTEM AND KIDNEYS (PLANTS CONTAINING SAPONIN-GLYCIDE)
    Saponin glycosides are hemolytic as well as irritating to the gastrointestinal tract. By their chemical nature, saponins are derivatives of triterpenes, however, steroid compounds are also found among them. In plants, they are contained from negligible amounts up to 30-50% (A. D. Turova et al., 1965). Plants containing saponins are widely distributed in the plant world.
  6. DAMAGE AND DAMAGE TO CELLS AND TISSUES. REASONS, MECHANISMS, TYPES OF IRREVERSIBLE DAMAGE. NECROSIS. APOPTOSIS
    Under the influence of excessive physiological as well as pathological stimuli, the process of adaptation develops in the cells, as a result of which they reach a stable state that allows them to adapt to new conditions. If the limits of the adaptive response of the cell are exhausted, and adaptation is not possible, cell damage occurs. To a certain extent, cell damage is reversible. However, if
  7. Mechanical damage
    Fractures One of the most common injuries in childhood is fractures, they make up, according to various sources, from 20 to 25% of all the lesions with which patients go to trauma centers. Nature provides for some mechanisms to protect the child from fractures: this is a developed, dense cover of soft tissues, which, like a pillow, weakens the force of impact when falling, and more
  8. MECHANICAL DAMAGE TO PREGNANT WOMEN
    Injuries during different periods of pregnancy complicate the obstetric situation and can pose a direct threat to the life of the pregnant woman herself. According to the generally accepted classification, mechanical damage is distinguished by severity and localization. Light injuries in the I and II trimester of pregnancy (up to 28 weeks), as a rule, do not affect its course, do not require obstetric-gynecological intervention, and more often
  9. Mechanical damage to the ear
    From a hematoma. A hematoma is a hemorrhage between the cartilage and perichondrium of the auricle or, sometimes, between the perichondrium and the skin. The causes of othematoma are injuries of the auricle in wrestlers, boxers, people with heavy physical labor, with prolonged pressure of a hard pillow or other item placed under the head, especially in people with impaired blood circulation, mainly in the elderly
  10. SOFT TISSUE DAMAGE
    They are found mainly in dogs, but are often observed in other animals. Appear as a result of bites or cuts of parts of the body during animal walking in the early morning or late evening, when it is difficult to count on outside help. {foto8} Bites from bites can be on the head, neck and trunk of animals. With cat bites, one or two puncture wounds left by sharp fangs are possible. At
  11. PLANTS CAUSING PREVIOUSLY LIVER OF THE LIVER
    Lupine - Lupinus L. Annual plant up to 1.5 m high. Leafy stem. The flowers are quite large, collected by brushes. Seeds of various colors. In Russia, a large number of lupins is growing. Among them, lupine is narrow-leaved, yellow (Fig. 17), many-leaved, white. Cultivated in the European part of Russia. Lupine toxicity is associated with the presence of alkaloids lupine, spartein, lupinidine
