U zwierzat dotknietych hipomagnezemia obserwuje sie zmniejszone przyrosty, obnizona mlecznosc, zabu¬ rzenia plodnosci, utrate kondycji, obnizona odpornosc i inne niespecyficzne objawy. Obecnie wykrywanie niedo¬ boru magnezu u zwierzat polega na analitycznym oznaczaniu stezenia magnezu w plynach biologicznych pobra¬ nych od podejrzanych o hipomagnezemie zwierzat. Przewaznie oznacza sie stezenie magnezu w surowicy krwi, rzadziej w moczu lub w slinie.Wada takiego postepowania przy masowym zastosowaniu sa trudnosci wynikajace z koniecznosci dyspono¬ wania zapleczem laboratoryjnym, dlugim okresem czasu od momentu pobrania próbki do chwili otrzymania wyniku oraz znacznym kosztem wykonania analizy. Trudnosci te sprawily, ze dotychczas nie przeprowadza sie masowych badan wykrywania hipomagnezemii u zwierzat.Celem wynalazku jest opracowanie sposobu szybkiego wykrywania niedoboru magnezu u zwierzat we wczesnym jego stadium. Cel ten osiagnieto przez wykorzystanie zjawiska wystepowania magnezu w moczu o stezeniu wiekszym niz 100mgMg/dm3 u krów dostatecznie zaopatrzonych w magnez i o stezeniu ponizej 50 mg Mg/dm3 w przypadkujego niedoboru.Sposób szybkiego wykrywania niedoboru magnezu u zwierzat, zwlaszcza u bydla wedlug wynalazku pole¬ ga na tym, ze do odmierzonej ilosci badanego moczu dodaje sie odmierzona ilosc odczynnika, stracajacego ilosciowo zawarty w moczu magnez w postaci latwo opadajacego osadu i nie tworzacego osadu z innymi niz magnez skladnikami moczu, a okreslenie stezenia magnezu w moczu dokonuje sie przez odczytanie objetosci opadnietego osadu w naczyniu odpowiednio wyskalowanym, przy czym wysokosc slupka osadu jest miara stezenia magnezu w moczu.2 70 599 Zasadniczym skladnikiem odczynnika jest 8-hydroksychinolina. Oprócz tego w sklad odczynnika wchodza zwiazki zapewniajace optymalne dla reakcji stracania pH oraz zwiazki uniemozliwiajace stracanie innych niz magnez skladników moczu.Przyklad I skladu odczynnika: 1 czesc wagowa 8-hydroksychinoliny, 5 czesci wagowych kwasu cytrynowego, 50 czesci wagowych chlorku amonowego, 15 czesci wagowych amoniaku, 25 czesci wagowych chlorku potasowego, 150 czesci wagowych alkoholu etylowego 96%, 754 czesci wagowych wody destylowanej.Przyklad II skladu odczynnika: 4 czesci wagowe 8-hydroksychinoliny, 20 czesci wagowych kwasu cytrynowego, 80 czesci wagowych chlorku amonowego, 25 czesci wagowych amoniaku, 30 czesci wagowych chlorku potasowego, 350 czesci wagowych alkoholu etylowego 96%, 491 czesci wagowych wody destylowanej.Wykrywanie niedoboru magnezu wedlug wynalazku wykonuje sie w naczyniu przedstawionym na rysunku, które w dolnej czesci posiada podzialke 1 sluzaca do odczytania objetosci straconego osadu oraz wyposazone jest w dwie kresy 2 i 3, z których pierwsza 2 sluzy do odmierzenia badanego moczu a druga 3 okresla ilosc odczynnika jaka nalezy dodac w celu stracenia magnezu. Tego rodzaju konstrukcja naczynia eliminuje koniecz¬ nosc uzywania naczyn miarowych.Zaleta wynalazku jest uzycie do badania moczu, w którym, w przeciwienstwie do krwi, stezenie magnezu ulega obnizeniu juz w bardzo wczesnym stadium jego niedoboru. Sposób wedlug wynalazku umozliwia ^ponadto przeprowadzenie pomiaru stezenia magnezu u zwierzat bez korzystania z zaplecza laboratoryjnego bezposrednio w gospodarstwie, jest tani i szybki oraz nie wymaga wysokich kwalifikacji personelu. Dzieki tym walorom moze byc masowo stosowany.

Authorized under a provisional patent: Instytut Zootechniki Zootechniczny Zakład Dos Doświadczalny, Grodziec Slaski (Poland) A method of quick detection of magnesium deficiency in animals, especially in cattle. in animals, especially in cattle, most often in high-yield cows, fed with fodder from intensively fertilized grasslands. This disease is latent, subacute and usually occurs without visible clinical symptoms. A symptom of diagnostic significance is a low level of magnesium in the blood serum, i.e. hypomagnesium. mia. In animals suffering from hypomagnesaemia, diminished weight gain, diminished milk yield, impaired fertility, loss of condition, decreased immunity, and other nonspecific symptoms are observed. At present, the detection of magnesium deficiency in animals is based on the analytical determination of the concentration of magnesium in biological fluids collected from animals suspected of having hypomagnesaemia. Usually, the concentration of magnesium in the blood serum is determined, less often in the urine or saliva. The disadvantage of such a procedure in the case of mass application is the difficulties resulting from the need to have laboratory facilities, a long period of time from the moment of taking the sample to the moment of obtaining the result and the considerable cost of the analysis. Due to these difficulties, no mass tests for the detection of hypomagnesemia in animals have been carried out so far. The aim of the invention is to develop a method for the rapid detection of magnesium deficiency in animals at an early stage. This goal was achieved by using the phenomenon of magnesium in the urine with a concentration of more than 100 mgMg / dm3 in cows sufficiently supplied with magnesium and with a concentration below 50 mg Mg / dm3 in the case of its deficiency. A method of quick detection of magnesium deficiency in animals, especially in cattle according to the invention, is that a measured amount of a reagent is added to the measured amount of test urine, which quantitatively loses the magnesium contained in the urine in the form of an easily settling sediment and does not form a sediment with other urine components than magnesium, and the determination of the magnesium concentration in the urine is made by reading the volume of the collapsed sediment in a suitably graduated vessel, the height of the sediment column being a measure of the concentration of magnesium in urine.2 70 599 The essential component of the reagent is 8-hydroxyquinoline. In addition, the reagent consists of compounds that ensure optimal pH for the reaction and compounds that prevent the loss of components other than magnesium in the urine. Example I reagent composition: 1 part by weight of 8-hydroxyquinoline, 5 parts by weight of citric acid, 50 parts by weight of ammonium chloride, 15 parts by weight Ammonia, 25 parts by weight of potassium chloride, 150 parts by weight of ethyl alcohol 96%, 754 parts by weight of distilled water. Example II reagent composition: 4 parts by weight of 8-hydroxyquinoline, 20 parts by weight of citric acid, 80 parts by weight of ammonium chloride, 25 parts by weight of ammonia , 30 parts by weight of potassium chloride, 350 parts by weight of ethyl alcohol 96%, 491 parts by weight of distilled water. Detection of magnesium deficiency according to the invention is carried out in the vessel shown in the figure, which has a scale at the bottom 1 for reading the volume of the lost sediment and is equipped with into two lines 2 and 3, of which the first the 2 is for measuring the test urine and the other 3 is the amount of reagent that needs to be added to lose magnesium. This type of vessel design eliminates the need for measuring vessels. An advantage of the invention is the use of urine in which, unlike blood, the magnesium concentration is reduced at a very early stage of its deficiency. Moreover, the method according to the invention makes it possible to measure the concentration of magnesium in animals without the use of laboratory facilities directly on the farm, it is cheap and fast, and does not require highly qualified personnel. Thanks to these values, it can be used on a large scale. PL PL
