A technical advisor working for you formulated a vitamin premix for a large swine producer and instructed him to use the premix at 6 lb./ton of the diet for growing-finishing (50-150 lb) pigs. The producer has fed the premix to 5 sets of pigs and is complaining that growth performance is poor. He strongly believes that the pigs are deficient in something and is asking for monetary compensation. Given the recommended use level for the premix and its composition (below), determine whether the premix will meet the corresponding vitamin needs of the pigs. Based upon your findings, recommend to your supervisor whether the technical advisor should be promoted or terminated. Would you make any changes to the premix or its inclusion level in the diet or both? Be specific in your remarks.
Vitamin Concentration (per pound of premix)
A 1,500,000 IU
D3 1,500 IU
E 9,000 IU
K 420 mg
B12 15 mg
Riboflavin 1,570 mg
d-Pantothenic acid 8,500 mg
Niacin 150 mg

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.
