V***J Lancaster Farming, Saturday, June 26, 1965 * , ,«»■ • "Summer Slump" (Continued trom .rage 1) ville, Md., has exposed dairy cows to a variety of tempera ture-humidity combinations in an artificial-climate laboratory. And he has found that cows can adjust amazingly well to the direct effects of heat and humidity. “The more tiials we lun,” Dr. McDowell says, “the more convinced we are that milk flew tends to decrease largely because of summertime prob lems that are the indirect not the direct result of hot weather.” Field studies in Georgia and Louisiana have confirmed these laboratory findings, and Dr. McDowell recommends that herd managers take sev eral steps to overcome prob lems brought on by hot weather: 1 Provide sufficient high- Ph. 397-5539 quality feed; avoid mature pasture grasses. 2 Keep animals from hav ing to travel far to feed, wa ter, and shade. 3 Allow grazing only dur ing the cooler time of day. 4 Control biting insects. 5 Provide enough shade and unpolluted water. Cattle in hot climates shouldn’t have to depend upon grass pastures for all their feed, McDowell says In the South, permanent pastures can support good milk production for only 40 days between June and November. Tough, mature pasture grasses are usually unsuited for summer feed. A cow ordinarily spends the energy equivalent of 1 to 3 pounds of milk per day by foraging for feed. Milk yield drops even more if the cow has to walk long distances to pasture, dunking trough, or shade When good grazing is avail- able, it should 'be restricted to the cooler hours of the day Cattle on pasture especi ally need help in fighting off biting insects, which are at their worst during the late evening and night The 'best solution of hot weather feeding lies in use of drylots In the Louisiana- Geoigia studies, cows fed hay, silage, and gieen chop in dry lots pioduced 98 percent of their cool-weather milk yield when daily temperatures aver aged 91 degrees at the after noon high and 70 degrees at the nighttime low Cows fed stoied iorages har vested at the proper stage of matinity pioduced 21 percent moie milk than cows on pas tuie Feed required per pound of weight gam for heif ei s vent down 27 percent, breeding efficiency was raised 11 percent, and total cost per unit of feed energy was re duced 25 percent Clean, convenient water is a hot-weather must, McDowell says Cows drink up to five times as much on hot- days as on cool ones and they’ll dunk three or four times moie often Water should be cool but not moie than 20 degrees below air tempera ture, cattle drink less if the water is coldei than that. Troughs should be fairly shal low, so that fiesh, cool wa tei added to the tiough does not sink through warm, stag nant water outside the leach of a cow’s muzzle. Shade is especially impor tant in hot climates that are also dry less so in those where daytime humidity stays above 60 percent Shades 12 to 14 feet high are most suit able for dry climates; for humid climates they should be only 9 to 12 feet high.
