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

Darrel conducted an experiment with the following procedure: fill two cups with ice water. place an uninflated balloon snuggly onto your left index finger. blow a little air into an identical balloon, and place it onto your right index finger. place both fingers into the cups of ice water. darrel noticed that his right finger felt warmer in the ice water than did his left finger. which of the following does the experiment show? a. air is a good radiator of heat. b. air is a good insulator of heat. c. air is a good conductor of heat. d. air is a good convector of heat.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
