— Lancaster Farming. Saturday. Dec 20, 1975 52 Solar-heated house nears completion GREENVILLE, S.C. - Construction of a medium priced, three-bedroom family dwelling heated with solar energy, designed by the U.S. Department of Agriculture's Agricultural Research Service (ARS), is nearing completion. The completely insulated attic of the house serves as the solar collector and a 12- mch thick layer of crushed rock beneath the floor of the house serves as a heat storage tank. The bouse is conventional in other respects. The beating system is simple in design. Two layers of translucent fiberglass replace conventional roofing on the south roof slope and transmit sunshine or solar energy into the attic where it is absorbed by a black plywood floor. This heats the air m the attic and the heated air is circulated to heat the house and the rocks beneath the bouse. The heated rocks can store a four-day supply of heat to warm the house at night and during cloudy or rainy weather. The solar heated house Spud count announced HARRISBURG - As of December 1, the 1975 Penn sylvania fall potato crop is estimated at 6,814,000 hundredweight (cwt.) or seven percent lower than last year, according to the Crop Reporting Service.

Zomig. It is part of the ARS effort to lower the operating costs of rural housing with a low cost, low-maintenance heating system using solar radiation as the energy source. Such a heating system could be modified to match the demands of other geographic and climatic areas. Zomig predicts that at least 75 percent of the house heating load during the coldest month in Greenville can be supplied by solar energy. To meet the small need for extra heat during the heating season a slightly larger than nonnal hot water heater is used as an auxiliary heat source. Hot water is automatically pumped from the hot water supply to heat exchanger in the air distribution system when and if the house has no solar heat in the attic or in storage. The rocks that are used as a heat storage tank in winter can keep the house at a to fewer acres harvested than was expected at that time. U.S. fall potato production was estimated at 271.9 million cwt., and is one percent above last month but 6 percent below the 1974 record harvest. pleasant daytime tem perature during the warm months. This is achieved by bypassing the heat from the solar collector and allowing the rocks to cool at night. Helio-Thermics, Inc., builders of the house is cooperating with ARS in the project. The Greenville firm developed the solid-state electronic controller which operates the house’s energy conserving system. The ARS Rural Housing Research Unit will monitor the performance of the prototype house through four seasons starting this winter, according to Mr. Zomig. Performance during the year will be measured while the house is occupied. Although designed by ARS and built to ARS specifications, construction is being done by the EVERY $l.OO IN AUREOMYCIN YOU PUT INTO YOUR HENS RETURNS $l3 IN EXTRA EGGS The Aureomycin Week-a-Month Layer program helps you get maximum egg production on a minimum of feed. For an investment of per hen per year in AUREOMYCIN® chlortetra cycline, experience shows you can expect an extra dozen eggs per bird—or an extra return of $4OO per f,OOO birds (with eggs at 40^/doz.). This figures out to a return of $l3 for every $l.OO in AUREOMYCIN you put into your layers. The program is easy to manage. Just feed hens 100 grams of AUREOMYCIN chlortetracychne per ton of feed for one week each month as long as birds are in production. Trials show AUREOMYCIN also saves one-quarter pound of feed for every dozen eggs produced. This program is equally effective for broiler breeders. Based on commercial trials, 3<(. in AUREOMYCIN per breeding hen produces six extra chicks per breeder or a total of $450 extra return a year from every 1,000 birds (with chicks at 7.5*).

The prototype bouse has a calculated average heat loss of 216,000 BTU per day in the Greenville area in January. In this same month there should be available a calculated 457 BTU per day of solar energy per square foot of transparent roof, assuming the prototype house will have the same 43 percent attic collector ef ficiency as a small test house previously built by the Rural Housing Research Unit.

The program is easy to manage. Just feed chicks 200 grams of AUREOMYCIN® chlortetracycline per ton in the first pound of feed (with L 25% sodium sulfate and 0.8% calcium). This program, which provides chicks with high levels of AUREOMYCIN in the cntical first three weeks, helps reduce mortality and aids in the prevention of synovitis. Thais with over 14 million broilers show that weight improvements and feed savings produce an extra return of $8.28 per 1,000 birds (with feed at 6tf/lb. and broilers at IBtf/lb. live weight). This figures out to a return of $2.76 for every $lOO in AUREOMYCIN you add to your feed. Less than l/3e per bird is all it takes to provide AUREOMYCIN in the first pound of feed Start your next house of chicks on the First'Pound-of'Feed program with AUREOMYCIN.
