Chemical Composition of Agropyron desertorum as Related to Grass Tetany 1

Magnesium Concentration in Agropyron desertorum Fertilized with Mg and 1st

Magnesium Concentration in Agropyron desertorum Fertilized with Mg and 1st H. F. Mayland and D. L. Grunes2 of humid pastures with N and K often increases the i id of tetany 3 4 nc ence ( , 4). Grass tetany, a Mg deficiency in ruminants, is responsible for large economic losses throughout temperate regions. Significant livestock losses occur in the semiarid western United States primarily when l...

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...

Effect of oral potassium and sodium chloride on plasma composition of cattle: a grass tetany related study.

M ANY factors have been implicated in the etiology of grass tetany including hypomagnesemia, hypocalcemia, class of animal, stage of production and various dietary factors. Hypomagnesemia has been the most consistent clinical symptom. Elevated levels of dietary potassium (K) (Kunkel, Burns and Camp, 1953; Ward, 1966a) and nitrogen (Redmond, 1950; Metson et al., 1966) have lowered plasma magnesi...

Mycoplasma agalactiae 1- Chemical Composition of M. Agalactiae

اثر آللوپاتی گیاه اسپند (Peganum harmala L.) بر دو گونه مرتعی Agropyron desertorum و Agropyron elongatum

با توجه به حساسیت مختلف گونه‌های علف هرز به مواد آللوکمیکال گیاه اسپند، می­توان به کشف گونه‌های مقاوم به مواد بازدارنده این گیاه، در امر اصلاح و احیاء مناطق بحرانی مراتع کشور امیدوار شد. این تحقیق به­منظور تعیین توان آللوپاتی گیاه اسپند (Peganumharmala L.)  بر دو گونه مهم اصلاح مراتع (Agropyrondesertorum  وAgropyronelongatum) انجام شد. اثر نوع پودر (هوایی و زیرزمینی)،  نسبت (در پنج سطح 0 ، 5، 1...
