<p><strong>Why do I get a higher requirement for selenium in PC-horse than in the national (Here: Swedish) feeding recommendations, which says 0.2 mg per 100 kg of body weight?</strong><br /><br /> PC-Horse calculates the selenium requirement according to the official US norm NRC2007. This norm stipulates a minimum selenium intake of 0.1 mg per kg DM (dry matter) in rations for all horses. This calculation is however complicated by the fact that NRC2007 recommends different DM intakes for different categories of horses. For example, an adult horse in the maintenance category requires 2% of body weight per day (2 kg dry matter per 100 kg of body weight). For exercised, pregnant and lactating horses, 2.5 to 3.0% of body weight is recommended.<br /> <br /> In PC-Horse we use data on the individual horse, and take into account that the NRC2007 norm stipulates a “minimum” amount required to keep the horse fit and healthy. Therefore we increase the requirement by 20% in the recommendations listed by the program to create an optimised supply of the nutrient. The Swedish recommendation does not take these factors into consideration, and therefore gives a somewhat “cruder” calculation of selenium requirements than you will obtain through the use of PC-Horse (Dr Dag Austbø).</p>
<p><strong>What is the meaning of the units used in PC-Horse?</strong><br /> &nbsp;<br /> One kilogram (kg) is 1000 gram<br /> One milligram (mg) is 1/1000 of a gram, or 0.001 g<br /> One microgram (mcg or ug) is 1/1000 of a milligram, or 0.001 mg<br /> &nbsp;<br /> Some producers of horse feeds use the unit ug/kg when declaring the concentrations of nutrients like vitamin B12 or selenium. &nbsp;<br /> A B12 content of 100 ug/kg should in PC-horse be entered as 0.1 mg/kg, since most vitamins and trace mineral concentrations are presented in mg/kg.<br /> The vitamins A, D and E are still declared as international units (IU) per kg of feed.<br /> 1 mg of vitamin E equals 1 IU. For the vitamins A and D there is no such simple relationship.</p>
