Management practices to overcome the incidence of grass tetany.
To minimize the incidence of grass tetany, winter pastures should be established on soils containing Mg-rich minerals, drainage should be improved on five-textured soils, legumes should be included in the sward and soil pH should be at least 5.5. Liming acid soils with dolomitic lime increases forage Mg by supplying Mg and by raising soil pH. Calcitic lime applications also can increase Mg avai...
متن کاملUsing plant breeding and genetics to overcome the incidence of grass tetany.
Plant breeders developing cultivars to minimize the hazards of grass tetany are concentrating largely on increasing herbage Mg concentrations in cool-season (C3) grasses. Significant genetic variation has been found for Mg, Ca and K concentrations within C3 grass species studied to date. For most C3 forage grass species, heritability estimates are highest for Mg, slightly lower for Ca and lowes...
متن کاملCommon metabolic diseases of cattle: ketosis, milk fever, grass tetany, and downer cow complex.
Reid, in the 50th anniversary issue of the Journal of Dairy Science, stated that "in 1906, the average cow in the United States produced approximately 2,500 lb of milk; in 1956, she produced more than 5,000 lb." During the next 25 yr, the average annual milk production per cow has more than doubled, and some individual herds average more than 9,000 kg per cow per year. Selection of vastly impro...
متن کاملUse of animal breeds and breeding to overcome the incidence of grass tetany: a review.
British breeds of cattle are not so effective as Zebu in extracting nutrients from low-quality roughages, and these breeds differ in their nutrient metabolism and animal physiology. Breeds of cattle may differ in their requirements for Mg. Brahman cows are less susceptible to death from disease and metabolic disorders than are British breeds of cattle, whereas cows with 50% or greater dairy bre...
متن کاملAdequate Soil Phosphorus Decreases the Grass Tetany Potential of Tall Fescue Pasture
Grass tetany is a nutritional disease of ruminants caused by low dietary Mg. Previous research has shown that early spring P-fertilization increases the leaf Mg concentration of tall fescue (Festuca arundinacea Schreb.) hay. However, little is known about how P-fertilization alters the mineral concentration of tall fescue under grazing. Our objective was to compare, under grazing, the Mg, K, Ca...
