Methods Of Treatment

Health of dairy cows ensures human health, so it is important that dairy products do not contain antibiotics that are used to treat any inflammation, including mastitis. In Russia at present, the problem of mastitis in cows exists with both attached and loose housing of cows. Mastitis of dairy cows are the great problem in milking husbandry. Losses from mastitis in milk yield can reach 15-20%. The main reasons for the occurrence of nonspecific mastitis of cows are the shortcomings of the working components of the milking machine: the degree of deterioration of the nipple rubber and the violation of machine milking technology (the reduction in pre-milking time and vacuum fluctuations account for 70% of all causes). Treatment of mastitis with antibiotics is effective, but not environmentally friendly and unacceptable. For the treatment of inflammation of the udder, it is necessary to use more environmentally friendly methods of treatment, one of which is the exposure to ultra-high frequency electromagnetic field tested by medicine. Use of three types of medical-mobile milking machines with the same method of exposure to ultrahigh-frequency electromagnetic fields on cow's nipples through electrodes in milking cups: LPDA-1-UHF, LPDA-2-UHF and LPDA-UHF-30 M, is described in the article. Author proved that cows with subclinical forms of mastitis recovered faster during milking with exposure to the ultrahigh frequency than when treated by antibiotics, and milking with the ultrahigh frequency device helps to recover 82% of the affected quarters with clinical forms and 100% of cows with subclinical forms of mastitis or with udder irritation. The high efficiency of the method of exposure to electromagnetic fields of the ultrahigh frequency during machine milking by means of medical-mobile milking machines LPDA-UHF for the prevention and treatment of mastitis of cows was shown.

The Difference

Abstract The report of introduced techniques and theoretical, analytical and experimental studies of foreign and our national scientists in recent years are given in this article. it has been established that treatment with a high frequency electromagnetic field achieves a high efficiency in drying the cocoon and killing pupae. The shell of the cocoon does not heat up with this method. This is explained by the fact that the high frequency energy is absorbed mainly in the pupa because of the difference of the dielectric constant, which leads to the heating of the pupa to 90-95 ° C and they die within 30 seconds depending on the power.

The present study was aimed to measure the haemoglobin oxygen saturation and the pulse rate at teat level on dairy cows after and before milking, using a low cost pulse oximeter developed especially. The pulse oximeter has been tested during a three days of field test involving 18 Holstein Friesian cows raised in a commercial farm located in Northern Italy. The results highlighted that there is a significant difference both in haemoglobin oxygen saturation (SpO2) and pulse rate before and after milking considering the entire sample of animals. By dividing the sample according to the milking time (fast < 8 min and slow > 8 min), a significant difference between fast and slow cows has been observed for SpO2, whilst no difference has been noted considering the lactation stage (< 70 DIM and 71-140 DIM). About the pulse rate, on the contrary, milking time and lactation stage were not significantly different. This confirms that machine milking can create stress to the teat evoking circulatory impairment of its tissue and that pulse oximetry could be useful for detecting machine milking-induced alterations of teats. In perspective, the pulse oximeter could be used as a part of a monitoring system of the milking machine, enabling to change its operating parameters in order to minimize the mechanical stress on the teats.

Point Of Reference

High-frequency electromagnetic fields can have a negative effect on both the human body and electronic devices. The devices and systems utilized in radio communications constitute the most numerous sources of electromagnetic fields. The following research investigates values of the electric component of electromagnetic field intensification determined with the ESM 140 dosimeter during the flights of four aircrafts—Cessna C152, Cessna C172, Aero AT3 R100, and Robinson R44 Raven helicopter—from the airport in Depultycze Krolewskie near Chelm, Poland. The point of reference for the obtained results were the normative limits of the electromagnetic field that can affect a pilot in the course of a flight. The maximum value registered by the dosimeter was E = 3.307 V/m for GSM 1800 frequencies.

The Impact

The physiological aspects of the implementation of the cow milk transfer reflex during machine milking are the result of exposure to the threshold force of a given value of a variable vacuum and simultaneous mechanical irritation by the teat rubber of the udder of the cow udder system. This effect leads to the discovery of sphincters with the subsequent release of the hormone oxytocin by the pituitary gland and the milk accumulation from the alveolar udder tissue. Signal environmental factors (sounds of a vacuum pump, milking machines, feeder) cause reactions in cows not only by irritation but also by frequency. It has been established that exposure to a high-frequency electromagnetic field destroys most of the common causative agents of mastitis-staphylococci, streptococci. For the treatment of mastitis, stimulation of lactation and the reflex of milk flow in cows, it is promising to apply the effect of a high frequency electromagnetic field modulated by radio frequencies, which contribute to the conversion of electromagnetic field energy into energy of nerve impulses and chemical reactions of mitochondrial cellular mechanisms of udder alveolar tissue cells. The use of alternating sets of specific frequencies of a modulating electromagnetic field of high frequency allows the alternation of “killer” frequencies for microbes with stimulating secretion of alveolar cells of the udder and with frequencies that act anti-inflammatory. It is essential to determine the frequencies that create protective inhibition from exposure to extreme irritations of milking factors (increased vacuum, durable worn nipple rubber). With prolonged exposure to an electromagnetic field, such frequencies a repeating conditioned stimulus of a weak strength, which precede and accompany the impact of the milking machine, and stimulate the activity of the nerve centers of the milk yield reflex in cows, creating a dominant lactation.

Background: Previous studies have shown that exposure to high frequency electromagnetic fields induces alterations in simple organic systems such as proteins in bidistilled water solution. Objective: The aim of this study was to test the shielding action of sodium chloride in bidistilled water solution against exposure to a high frequency electromagnetic field, in order to evaluate if the addition of NaCl in proteins aqueous solution can be considered a valuable bioprotector against electromagnetic fields. Method: Samples of 250 μl of different hemoglobin aqueous solutions, in the absence or presence of sodium-chloride, were exposed for 3 hours to an electromagnetic field at 1750 MHz at a power density around 1 W/m2 emitted by an operational mobile phone. Fourier Transform Infrared Spectroscopy was used to study the effects of exposure on the secondary structure of hemoglobin also in the presence of sodium-chloride. Results: Spectral analysis evidenced that significant increase in intensity of the Amide I and II vibration bands in hemoglobin bidistilled water solution occurred after exposure to the electromagnetic field. This result can be due to the increase of dipole moment of the protein due to the alignment of α-helix towards the direction of the field. In contrast, no appreciable change was observed in hemoglobin in sodium-chloride water solution after exposure. Conclusion: This protective effect of sodium-chloride can be explained by the orientation of water molecules due to the strong electric field around each ion that reduces the possibility of rotation of the protein in response to an applied electromagnetic field.
