“…This result is a consistent with the observation which confirms the presence negative correlation between Na content of grass (Na deficiency-the author) and the emergence of symptoms of tetany [46]. Finally, adding NaCl into feed cows could be prevented grass tetany [47].…”

Hypomagnesemia Tetany in Cattle

Grass tetany, sometimes called grass staggers or hypomagnesemia, can be a serious problem in Syria with cattle grazing small grain or ryegrass pastures. hypomagnesemia tetany has been known under a variety of names, including magnesium tetany, lactation tetany and grass staggers, but most of these terms have been discarded because the disease is not always associated with lactation or with grazing animals.The exact cause of hypomagnesemia tetany in ruminant animals is a dietary deficiency of magnesium that may be a contributory factor. Some research workers consider the condition to be caused by a cation-anion imbalance in the diet, and Some research workers believe that high intake of the element (K & Na) may interfere with the absorption and metabolism of magnesium in the animal, which may be an important factor in the etiology of hypomagnesemia tetany.Although the exact cause of hypomagnesemia is still uncertain, the primary factor would appear to be inadequate absorption of magnesium from the digestive tract. A high degree of success in preventing hypomagnesemia may be obtained by increasing the magnesium intake. This can be effected by feeding with magnesium rich mineral mixtures or, alternatively, by increasing the magnesium content of pasture by the application of magnesium fertilizers.

“…In fact, a summary of results reported by Cairney (1964) from a survey of cattle in the Hawke's Bay region (Table 7), taken in conjunction with the associated chemical composition of the pastures from a selection of these farms (Saunders et al 1964) clearly indicates that the occurrence of metabolic disorders (hypomagnesaemic tetany) was greater inland, where the pastures were higher in potassium and much lower in sodium, than in the coastal areas; a further feature of this survey was that the high magnesium level found in both areas was above that normally associated with the incidence of hypomagnesaemia (Kemp 1960). Hypomagnesaemia is normally associated with low blood levels of magnesium, but a number of workers have suggested that a low sodium intake by animals may contribute to the development of this disease (Kemp 1958;Lehr 1960;Paterson & Crichton 1960;Ross 1960;Butler et al 1963). Moreover, cows which have been deliberately deprived of sodium in their diet are t all values are expressed as parts per million reported to have shown similar symptoms to hypomagnesaemia, shivering, incoordination, weakness, cardiac arrhythmea, and death (Smith & Aines 1959).…”

Sodium and potassium content of topdressed pastures in New Zealand in relation to plant and animal nutrition

An extensive geographical survey was carried out to obtain information on the sodium and potassium content of topdressed grass-clover pastures in New Zealand. Results indicate that in many areas, especially away from the influence of sea spray, herbage sodium levels are below those estimated to be required by grazing animals. The associated potassium contents of these pastures, particulady in the North Island. are well in excess of animal needs and generally are more than adequate for plant nutrition. The possible effects on animal health of a low dietary intake of sodium coupled with excessive amounts of potassium are discussed. The importance of sources other than the plant in supplying sodium for animal needs is also pointed out. It is emphasised that there is an urgent need to assess fertiliser policy more in terms of the requirements of both plants and animals, by a plant analysis and balance sheet approach.

“…Patterson and CHchton (8) have recently successfully used salt in the control of hypomagnesaemia in large numbers of cattle on spring grass. They have suggested that hypomagnesaemia may be increased by low sodium levels in herbage and quote a number of Dutch workers on this point {e.g.…”

Results are given showing the effects of applying nitrogen, phosphorus, potassium, sodium and magnesium on the yield and mitieral composition of herbage cut repeatedly at the silage stage over a 3-year period. Grasses and clovers were separated before analysis. A combination of nitrogen and potassium was essential for the maintenance of high yields. Superphosphate did not increase drymatter yields. 4 cwt. of common salt was ineffective, even under conditions of acute potassium deficiency; it reduced responses to potash and decreased yields when given with potash.Ammonium sulphate and common salt greatly increased sodium uptakes and muriate of potash depressed them. Potassium contents were greatly reduced by repeated nitrogen applications and muriate of potash gave consistent and significant increases. Potassium-deficient grasses contained more sodium than potassium.Ammonium sulphate increased magnesium contents and muriate of potash reduced them. There was a marked tendency for both effects to be more significant in late-season cuts. In late May the effects were small. 22 and 44 Ib. Mg/acre as magnesium sulphate had variable effects on herbage magnesium. These changes are discussed in relation to hypomagnesaemia.None of tbe fertilizer treatments altered the calcium contents of either grass or elover.
