The U.S. Energy Information Administration reports propane prices gradually increased from under $2.40 a gallon in early October, 2013 to almost $3.00 per gallon by mid-January, 2014. By the end of January prices had spiked to $4.00 per gallon, rates that that many in the U.S. had not seen before. According to the National Propane Gas Association today’s high prices were influenced by a series of 2013 events.
- Increasing exports are impacting supply. In 2013 20 percent of the U.S. propane was exported, up from 5 percent in 2008.
- The nation’s record setting corn crop was harvested later and at higher moisture requiring more drying fuel than normal.
- A pipe line that normally transports propane into Minnesota has been shut down for repairs forcing propane providers in Minnesota to dip down into Iowa to access the supplies they need, causing a shift in regional supplies.
- An early December storm initiated a winter that has been longer and colder than in the immediate past. According to the Propane Association, thus far the number of heating degree days this winter is 10 percent higher than normal.
While propane stocks are not worrisome they are significantly below last year’s inventory. The Weekly Petroleum Status Report published by the U.S. Energy Information Administration reports the Jan.31, 2014 propane inventory was 44 percent below the 2013 levels and 34 percent below 2012.
With cold winter weather continuing in February, pork producers are looking for ways to save fuel and reduce their overall energy bill. Producers still have the ability to employ some management changes to different areas that may either save on energy cost, increase pig comfort or both.
Michigan State University Extension recommends producers make sure the barn’s ventilation and heating systems are set to meet the needs for the stage of growth and number of pigs in the barn. Table 1 provides the recommended ventilation rates based on phase of production for cold, mild and hot weather. Check to make sure the needs of the pigs are being met but the room is not being over ventilated. Use the listed cfm in each fan’s manufactures owner’s manual to calculate the cfm being provided then compare the calculated cfm to the recommended needs of the pigs. At times finishing barns will be half filled one week with the remainder of the pigs placed in the barn the following week. During that time span between when the first set of pigs arrive and when the second set of pigs is delivered, the minimum ventilation should be set to meet the needs of the number of pigs currently in the barn, not the number of pigs when the barn is at full capacity.
