The invention relates to the field of veterinary medicine, relates to a method of early diagnosis of omphalitis in calves.

The omphalitis (Omphalitis) - inflammation of the umbilical cord. Manifested in locally-inflammatory or diffusely metastatic form. The forecast is questionable, because the process can easily spread up the umbilical blood vessels and end with septicemia, pyemia or septicemia (sustavam). When locally-inflammatory form of omphalitis the disease is usually in moderately severe and mild. In the diffuse-metastatic form of the disease is difficult /1, 2/.

According to domestic and foreign researchers omphalitis has a wide distribution and percentage incidence of calves varies from 20 to 60% /3, 4/.

A known method for the diagnosis of omphalitis, involves inspection and palpation of the umbilical region. Inflamed, the umbilical cord is swollen and painful. Sometimes in severe swelling of the cover surrounding the umbilical cord to the abdomen, increase local and sometimes total temperature. The stump of the umbilical cord becomes wet rotten dirty brown /2, 5/.

The disadvantage of this method is that the inflammation of the navel becomes visible on day 2-3 of life of the newborn, sometimes on the 7th day, which does not allow treatment and prevention activities at the initial stud and the emergence of omphalitis.

The technical result of the invention is earlier identification of omphalitis in calves.

The technical result is achieved by measuring the diameter of the umbilical cord by Kalimera or caliper in the first 1-3 hours of life of the calf. When the diameter of the umbilicus than 18 mm from the calf in the first day develops omphalitis.

In the experimental study found that reducing the concentration of oxygen in the blood of the fetus leads to enlargement of the umbilical vessels, increasing the concentration - contraction /6/.

The method is as follows.

In calves during the first 1-3 hours after birth by Kalimera or Vernier caliper to measure the diameter of the umbilicus. When the diameter of the umbilicus than 18 mm is diagnosed early manifestation of omphalitis.

Early diagnosis of omphalitis using the proposed method was carried out in FGUPS "Kirov" novousmansky district of Voronezh region, at the experimental station of the Voronezh state agrarian University (Voronezh) in 2002-2003 164 newborn calves.

Data analysis in the scientific and patent literature revealed no diagnostic method of omphalitis in calves after birth (within the first 1-3 hours of life) using the measurement of the diameter of the umbilicus, which indicates compliance of the proposed technical solution the criterion of "novelty".

The essence of the method is illustrated by example.

Example

In the household, the length is correctly affected with the disease omphalitis, took 66 newborn calves. After birth, calves were measured by Kalimera the diameter of the umbilicus. For the animals within one and a half months were clinical observation, defined body temperature, heart rate, number of respiratory movements accounted appetite, sucking reflex. The animals performed the inspection and palpation of the navel, take into account the incidence, course and outcome of disease. The results of the experiments presented in the table.

Table

As can be seen from the table, out of 42 calves, in which the diameter of the umbilicus in the first hours of life exceeded 18 mm, for 2-3 day ill of 85.7%, and for 3-7 days still to 14.3% of the animals.

At 31 calf this group, the disease progressed died NGOs-severe form. Disease duration was 29±2,03 days, palpation of the painful navel, compacted, the diameter of the umbilicus at the beginning of the disease was 2,08±0,08 cm, in the midst of disease 2,95±0,07 see the Stump of the umbilical cord has fallen by 15-20 day life (in clinically healthy this took place on 8-10 day). These calves sucking reflex was decreased, body temperature was 39,0±0,12°C, heart rate of 101.7±6,2 beats/min, respiratory rate of 24.7±3.3 recreation/min. Disease proceeded with more frequent defecation.

11 calves from among those in which the diameter of the umbilical cord exceeded 18 mm, the disease was in a severe form. Disease duration was 24.7±8 days; the diameter of the umbilicus at the beginning of the disease was 2,33±0,17 cm, in the midst of disease 4,17±0,66 cm; the stump of the umbilical cord fell off on 18-28 day life. The disease was accompanied by more frequent defecation, the depressed state, the tension of the abdominal muscles, strong pain response to palpation of the umbilical ring, body temperature was 39,9±0,21°C, heart rate 114,0±12,5 beats/min, respiratory rate of 43.3±7.5 stomach/min. Of 11 sick animals fell one calf due to umbilical sepsis.

Of the 24 calves, the diameter of the umbilical cord are not exceeded at birth to 18 mm, in the first 2-3 days of life not sick any animal; for 3-7 days from this group of calves is abolala 54,2% of the animals. However, the disease they proceeded in the form of light. The stump of the umbilical cord fell off on 12-15 day life. In diseased calves were kept sucking reflex. Body temperature averaged 38.6±0,16°C, heart rate 91±4,12 beats/min, respiratory rate 22±2.8 stomach/min

The tests showed the effectiveness and feasibility of the proposed method. The diameter of the navel of newborn calves can detect early signs of omphalitis, to predict its course and to carry out treatment and preventive measures.
