The next several articles will focus on cow-fnendly environments for the purpose of - Providing cows with a comfortable, healthy environment. - Building and remodeling facilities with cow comfort and future expandability in mind. Cows that are comfortable and healthy generally are more productive and more profitable. Thus, it is important to keep cow comfort and cow health in mind when remodeling or building new facilities. Dream of what your future dairy facilities should look like. Then, spend your money wisely by building "it" right the first Untie. In other words, be sure your plans have provisions for proper ventilation, for proper stall design, for proper pen layout, and for the efficient handling of cattle in a non stressful manner. It’s easier to incorporate these concepts into your building and remodeling plans at the Ume of construction, rather than dying to fit them in sometime later, after the construction has been completed. It helps you spend your capital more wisely and it increases the chance that you will end up with a more workable and a more cow-fnendly setup in the future. Some areas to focus on are air quality, shelters, rest areas, heat stress and social stresses Let’s begin with air quality. Our goal is to provide fresh air to the lungs without causing a cold draft. This helps to prevent respiratory problems and lung damage, it enhances cows' appetites and milk production, and it boosts their immune systems. The emphasis is on getting stale air out of the bam and replacing it with fresh air, not just circulating the stale air. Remember, cattle are cold weather animals. Fresh air is more important to them than warm temperatures' As you design your ventilation systems, seek expert advice Weigh Better On four Bottom Line ioneer® brand corn hybrids deliver more yield, more value and TEST INCOME/ BRAND HYBRID YIELD MST.

Pole bams should be constructed with 12-14 foot high eaves In addition to improving the cross flow of air, this height will also keep heat higher off the cows' backs Opening the ndge will allow trapped heat, moisture, odors and gasses to escape out the top Ridge vents should be 2 inches wide for every 10 feet of building width, with the minimum width being 6 inches If necessary, install fans to help exchange air. One fan should run continuously in order to exchange about 50 cfm of air per 1000 lb. of body weight. This will help prevent air from getting stale on cold days when there is minimal need to move air. As temperatures increase, you will need additional thermostatically controlled fans, set at around 50 degrees, to exhaust about 200 cfm per 1000 lb of body weight. For these exhaust systems to work properly, you need a fairly tight bam To provide fresh air to all areas of the stable, air inlets should be scattered uniformly around the perimeter of the bam It is highly desirable to locate some air inlets in the calf section of the bam so they are exposed to some fresh air (without drafts) rather than pulling the warm, stale, moisture-laden air from the older cattle over them , tim f ?, n u on hot days - y ol L need ‘0 move much more air. Tunnel ventilation works well for entilatmg tiestall bams m sununer. For typical tiestall bams of average width and height, two 48-inch fans are needed for each row of stalls. That should move air through the bam at about 3-4 mph (about walking speed) The fans are located in one end of the bam, and all side wall inlets are kept closed so all of the air is drawn in through large inlets at the opposite end of the bam You will need a lot of air inlet space - - about 1 foot of clear opening from wall to wall, or its equivalent, for each 48 inch fan' Controlling the direction of air flow in a tunnel system is very important Otherwise, dead air spots can develop. Avoid side wall openings, as they tend to shoot air to one side of the bam and create dead air S i' d , C !f e ? d t, W u" ope " mgs , are '"sufficient, try lifting floor boards from hay mows and bam floors at the inlet end of the bam Prevailing winds can also alter air flow in the bam, properly sized inlets can help reduce this problem by increasing air velocity and “straightening” out the flow of air Timnel ventilation systems are hot weather systems, not year-round systems' When temperatures drop be careful not to pull too much cool air over cows; you could chill them and set them up for pneumonia’ In hot weather, with all of the tunnel fans running, we may be exchanging air every 20 to 60 seconds depending upon the length of the bam and the number and size of fans However, in cold weather we would need to run fewer fans, and the air exchange is much less It takes longer for the air to move from one end of the bam to the other. Thus, it has more time to pick up moisture, germs and odors, and the cows at the exhaust end of the bam are constantly breathing fowl air - - not a healthy situation IORE BOTTOM LINE POWER.
