WEST CHESTER (Chester Co.) —Penn State University presented a three-day teleconfer ence via satellite in many Pennsyl vania counties, including Chester County, in early February. It was also picked up by several states in the Northeast and Mid west. Local extension agents coor dinated the workshops and con ducted 14 activity sessions over the three days. It was an excellent program to educate farmers about the basics and current research in dairy nutrition. A few of the highlights of the workshop were emphasized sever al times, and the following points can be helpful to all dairy farmers.' • Your finely tuned, computer generated dairy nutrition program is only accurate if you or your nutritionist has taken truly rep resentative samples of your forage. Samples should be taken every time hay or silage quality changes. Also, several samples of a particu lar forage should be taken and mix ed together to get a true sample for the lab. • Be sure you have an accurate determination of the dry matter for each forage. A change of just a couple percent either way can drastically affect the ration balance and, ultimately, milk production, and herd health • Do you it* :.y know how much your cows are actually consum ing? Determine accurate weights for each forage that is fed and, most importantly, deduct the amount that is refused.

How ever, if some is refused, the entire ration becomes out of balance. • When asked what your cows’ body weights are, do you automat ically say 1,300 pounds? This is another area that affects the ration that is required to reach peak pro duction. If yourradon is calculated for a 1,300-pound cow and your average body weight is really 1,400 pounds, your cows are get ting short-changed. • Different rations for different groups..We, in human nutrition, don* t eat or need the same nutrition at 10-years-old as we do at 25, or at 60! Cows are similar, with diffe rent nutritional needs based on their age and stage of lactation. The ideal setup would be to have separate rations for the following groups: first calf heifers; early dry cows (1 to 40 days); close-up dry cows (two weeks before calving); transitional group (first two weeks after calving); high group for pro duction; middle group for produc tion; low group for production. If you have 500 cows, you prob ably can create a system close to this, depending on your facilities. However, for the majority of farms, a high group, low group, and one ex' two dry cow rations could produce positive returns for production and herd health. • The dry cow programs on many farms are often neglected, whereas these should be top priori ty. What the cow does during the next lactation is largely reflected by her care and feeding during the dry period. These six points can be easily accomplished by all dairy farmers, and the results will be more profit.
