Control of mineral absorption in ruminants.
نویسندگان
چکیده
Ca absorption There is now clear evidence that both sheep and cattle absorb Ca from their gut according to need and that they can alter the efficiency of absorption to meet a change in requirement. For example, Braithwaite & Riazuddin (1971) have shown that young sheep with a high Ca requirement absorb Ca at a higher rate and with greater efficiency than mature animals with a low requirement. An increase in absorption and an increased efficiency of absorption also occurs in mature sheep when their requirement for Ca is increased through pregnancy or lactation (Braithwaite et al. 1969; 1970) or after a period of Ca deficiency (Braithwaite,

Trace mineral changes in response to organic and inorganic selenium supplementation
Twenty-one Lori–Bakhtiary sheep were randomly allocated into 3 groups to compare the effects of oral selenium nano particles (Se NPs) and sodium selenite (Na-Se) supplementation on serum selenium, copper, zinc, molybdenum, manganese and cobalt concentration. Groups 1 and 2 orally received Se NPs and Na-Se (1 mg/kg) for 10 consecutive days, respectively ...
متن کاملlNHlBlTlON OF TRACE MINERAL METABOLISM IN RUMINANTS
Trace minerals exist in cells and tissues of the animal body in a variety of chemical combinations, and in characteristic concentrations, depending on the trace mineral consumed and the tissue in which the trace mineral is metabolized (McDowell, 1992; Underwood and Suttle, 1999). Concentrations of trace minerals must be maintained within narrow limits in a cell (McDowell, 1989, 1992; Underwood ...
متن کاملPlantain Ash Enhances Dietary Mineral Elements Absorption in Pullets
Generally, only a fraction of the mineral ingested by an animal is effectively absorbed, while most are bound to other components such as fibre and then excreted. In this study, faecal mineral composition differentials were used as indicators of mineral uptake by pullets supplemented varying levels of plantain ash in their daily rations for nine weeks. Plantain stalk and root base samples were ...
متن کاملUtilization and Addition Sugars to Ruminants Rations
Responses to sugars in dry or liquid formvary from study to study. When fed in proper amounts, sugars should not depress ruminalpH, and there is some evidence that they actuallyhelp toprevent a drop in pH after consuming largemeals of concentrate by maintaining a highernumberoflactate-fermenting bacteria. Adding sugars doesprioritize the need for rumen degraded protein (RDP).we all know, sugars...
