the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle
نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولRelationship of soil test phosphorus and sampling depth to runoff phosphorus in calcareous and noncalcareous soils.
A study was initiated to investigate the relationship between soil test P and depth of soil sampling with runoff losses of dissolved molybdate reactive phosphorus (DMRP). Rainfall simulations were conducted on two noncalcareous soils, a Windthorst sandy loam (fine, mixed, thermic Udic Paleustalf) and a Blanket clay loam (fine, mixed, thermic Pachic Argiustoll), and two calcareous soils, a Purve...
متن کاملChanges in Soil Test Phosphorus and Phosphorus in Runoff From Calcareous Soils Receiving Manure, Compost, and Fertilizer Application With and Without Alum
Intensification of the dairy industry in southern Idaho has led to the overapplication of manures and a buildup of soil phosphorus (P), which is a potential threat to water quality in the region. As the use of alum has been shown to reduce both soluble manure P and runoff P from alum-treated manures, the objective of this study was to determine if surface applications of alum to dairy manure an...
متن کاملPercolation Phosphorus Losses in Calcareous Furrow-irrigated Soils
Groundwater seepage contributes to irrigation return flows and surface waters. Knowledge of phosphorus (P) concentrations and loads in percolation water that enters the vadose zone and groundwater is necessary to assess and manage water quality. We measured the P in water leached below the crop root zone in a furrow-irrigated Pormeuf silt loam. Vacuum operated percolation samplers were used to ...
