New-Style Hog House

New-Style Hog House Pork producer Arthur Nehring had the hog in mind when he drew up the plans for a new finishing confinement building for the family’s Pine Hills Stock Farm northwest of Hubbard Iowa First Nehring came up with the idea of using psychology on the pig Then he sought to reduce the amount of energy needed to keep the pigs warm by catching as much of the sun’s warmth as possible on cold winter days But most of all Nehring wanted a pork production unit which met the standards of the Iowa Department of Environmental Quality Nehring president of the family farm corporation believes his idea of using T-shaped concrete partitions within the 15 pens in the finishing building – which can house up to 2 000 hogs – is a natural He is now seeking to patent and copyright certain features of the new unit The chief purpose of Nehring’s concrete maze of partitions is to reduce fighting and scrapping among the pigs – one cause of hog losses in confinement buildings Nehring 68 and a hog farmer since 1932 explained how the maze worked “All of the corners in the pen give the hogs a chance to hide and a place to get away from it all ” he said “Out of sight out of mind And when one pig can’t see the other he tends to be less aggressive and there’s less fighting “The trouble with confinement is simply confinement itself And if you can let a hog get exercise and satisfy his exploratory drive – this is what my maze tends to do – the result is a more contented hog and less fighting ” he said Nehring is enthusiastic about results from the first few months experience with the new hog unit – both in the conduct of the hogs and in the saving of energy One day last week when the outside temperature was about 20 degrees the temperature insdie was 70 degrees On the coldest night in Hubbard this winter – about 20 degrees below Fahrenheit – Nehring reports the 1:30 a m temperature inside the hog house was 65 degrees These temperatures were achieved without the use of supplemental heat Only the warmth of available sunlight and the hogs heat the interior of Nehring’s hog unit No ventilation fans are used The key to such warm inside temperatures is the partitions Built of concrete they soak up the winter sun’s warmth and then give off heat into the night hours Nehring designed the finishing house which was constructed by Axtell Construction of Eldora at a total cost of about $190 000 The main feature of the building is the southern wall which is almost entirely sheets of translucent corrugated fiberglass material about 20 feet tall The hog house is 310 feet long and 40 feet wide and was built over an eight-foot deep pit which can hold a three-month supply of hog wastes The manure pit as well as the other aspects of disposing of animal wastes has the approval of Iowa environmental officials Nehring said that the cost of labor lumber and concrete came to about $160 000 while other facilities such as feed bins the feeders watering pipes and nipples as well as earth moving cost about $30 000 Nehring’s son Steve 38 who lives nearby is vice-president of the family corporation and resident-supervisor of the hog plant Another son Richard who lives in Washington D C is secretary-treasurer while Linda Jo Nehring Steve’s wife also is an officer The hog unit’s big window faces south The first morning rays of the sun extend almost to the back or northern wall of the pens so that the sun’s warmth hits into the pens early after a cold winter night Nehring said in the summer the positioning of the building is such that shade is cast over most of the interior of the unit Four-foot openings in the southern and northern walls of the hog house will permit summer breezes to cool the hogs So far Nehring has sorted out one load of hogs from various pens in his new confinement unit He noted an absence of fighting among the pigs bunched together from different pens for the first time He said the hogs like to nestle in the corners made by the T-shaped partitions Nehring also was surprised at the lack of manure build-up in the T-shaped partition corners where he and expected some of the hog wastes to accumulate “The hogs seem to sort of keep that area clean themselves ” he said Reprinted with permission from the Des Moines Register Des Moines Iowa For more details contact: Art Nehring 107 Michican Ave Iowa Falls Iowa 50126 ph 515 648-2768
