Insulation is used primarily to reduce heat loss from a building, and has become an important component in modern livestock and poultry buildings. For fruit and vegetable and frozen food storage construction, it is indis- pensable. "A well-insulated livestock building may need little or no supplementary heat over and above that provided by the livestock", says J.E.Turnbull, a research scientist at Agriculture Canada's. Engineering Research Service here. "A poorly insulated building has considerable temperature variation, and will affect livestock or poultry production more than when animals are housed at a. constant, comfortable temperature,' ' Mr, Turnbull says. For the fruit and vegetable farmer, use of good insulation can make supplementary heating unnecessary except during extremely cold weather. It also reduces electrical energy costs for refrigeration units in the summer. Condens ation, which can cause building deterioration, is another problem that proper construction can correct. "If the interior surfaces are kept warm by using enough insulation, then the air in contact with the surface is kept above the dew point and no surface wetting occurs," Mr. Turnbull says. Proper location of vapor barrier films (on the warmer side of the construction) prevents water vapor penetration into colder parts, which in turn could wet the insulation and rot the building. Insulation can also help to control noise and, provide• fire resistance if fire retardant materials are• used. , There are a variety of insulation types available to meet ,the needs of farm, construction. Fibrous blanket insulation made from mineral wool or 'glass fiber is relatively low cost, fire resistant and very effective in reducing heat loss. Loose-fill insulation made from mineral wool, vermiculite, cellulose fiber, or pulverized polystyrene plastic foam, can be poured into confined and awkward spaces. "In addition, there are rigid plastic foam insulations. These are rigid enough to support light-duty, insulated concrete floors in farm buildings," Mr. 'Turnbull says. "Another popular, though hazardous, method is for insulation contractors to spray the foam on surfaces to be insulated. Because it , can 'be sprayed over cracks and irregularities in construction to provide a continuous • layer, 'polyurethane foam can provide an airtight seal. "Any foam, whether or not it is treated with a fire-resistant additive, should be considered combustible, and covered with dt" ire sbioanr Several Tioenr ia'h'cotworsmuinchnuiennscuelattiohen "Always to ll in farm be sure buildings, there is enough insulation in walls and ceilings to prevent condensation, reevqe6nirief dthfiosr aamhoeuan is heat balance. ba thanAnd don't overlook the foundation perimeters when insulation is being installed," Mr. Turnbull says. oftiemelin Wingham Memorial Shop QUALITY SERVICE CRAFTMANSH11, Open Every Weekday Your Guarantee for Over 35 Years of CEMETERY LETTERING Box 158, WINGHAM JOHN MALLICK 10011.00144 Dairy cows & protein Despite skyrocketing prices for soybean meal, dairy cattle still require proper levels of protein in their ration to produce milk efficiently, says Jack Rodenburg, Ontario Ministry of Agriculture and Food dairy cattle specialist. Many dairymen respond to high supplement prices by feuding less protein, but this .can result in lower production and more health and breeding problems. Mr. Rodenburg says that although a general reduction in protein level of the ration is uneconomical, there are several ways dairymen can economize without reduciOg the production of their herds. • Ensure that the ration is • balanced to avoid wasteful overfeeding of protein. The level of protein required in the grain, mix will depend on the type and quality of roughage. Feed analysis and ration balancing services are available through local offices of the Ontario Ministry of Agriculture and Food. Substituting cheaper, protein supplements for soyean meal may -esult in a cost saving. These , supplements should replace soybean meal on the basis of their protein and total digestible nutrients (TDN) content. For example, one pound of dried corn distillers grain at 27 per cent protein and 78 per cent TDN replaces one-half pound of soybean meal (44 per cent protein and 72 per cent TDN) and one-half pound of corn (9 per cent protein and 78 per cent TDN). "Urea or non-protein nitrogen supplements are, cheaper than natural protein sources" says Mr. Rodenburg. "Because they are less palatable, they should be introduced gradually and fed at or beloW recommended levels." More emphasis on forage management especially maturity at harvest, can increase protein content of home grown roughages, and can reduce the amount of supplement needed to balance the ration. The protein content of hay stands decreases by as much as 2 per cent per week, after June 1. At present prices, this translates into an increase in the cost of a balanced grain mix of $16 per ton for, each week cutting is delayed. "Where hay or haylage is an important part of the ration, earlier cutting can result in a saving of several thousand dollars worth of protehi.This is one area where many dairymen can take major step' to reduce feed costae" Mr.& Mrs. Farmer and Family You are Cordially Invited— To spend an informal afternoon with us to meet and talk to the experts on Pesticides and their safe application You will have an opportunity to see The Diamond Shamrock Balloon will.be DEMONSTRATION PLOTS here to take yOu up 3500 feet to see' the MODERN.
