Our family farming history began with my great-great-... (nine generations ago) grandfather Johannes. He, his wife and three children left Saxony, Germany, on April 20, 1734, aboard the ship St. Andrew, mastered by Capt. John Stedman. They landed at Philadelphia on Sept. 22 and eventually settled our family’s first "New World" farm near Society Run in Frederick Township, Montgomery County, Pa., in 1743. Pig farming was our family’s specialty until the mid 1950s. A lot has changed since then. Our BQA cow–calf operation includes 100% grass-fed registered Red Angus, Hereford and purebred Beefalo; 30 to 35 pastured Duroc and Spot pigs; 100 Freedom Ranger broilers; and 90 Golden Comet and Buff Orpington layers. We organically maintain 80 acres, comprising 15 acres in rotational pastures, 15 acres in tillable cropland, and alfalfa/mixed grass hay on the balance. We have never used chemical pesticides or herbicides on our pastures or hay fields. We are not a "certified" organic farming operation, but we prefer the natural/organic approach to help promote sustainability.

Supplemental Winter Feeding
During the winter; "Quality" hay, "Mol-Mag" type mineral blocks or tub’s, and other supplements should be fed to help cattle produce enough energy to stay warm AND continue putting on their recommended daily gains. If feeding in a pasture during the winter months the feeding location should be moved often in order to avoid degrading the pasture. If animals are contained and fed at one central location a heavy use area protection (stabilized feeding area) should be installed to control manure and surface water runoff.
Adjustments to energy intake must be made to cope with winter conditions like everyone is experiencing today. A practical rule of thumb is to increase energy intake by 1% for each degree of coldness below the lower critical temperature of a cow. For practical purposes, a 20 degree F temperature can be used as the lower critical temperature. If the outside temperature is 0 degrees F with calm wind speed, then energy intake should be increased 20%. If daily TDN requirement during this period is 11.2/lbs., then an additional 2 pounds TDN are required to prevent stress on your cattle.
The National Research Council (NRC) indicates that a 1,300-pound cow requires a ration with 1.59 pounds of protein and 10.1 pounds of TDN during the middle third of gestation and 1.98 pounds of protein and 12.7 pounds of TDN during late gestation. There is considerable variability in the nutritional values of forages; therefore, it is important to have a laboratory analysis of your forages. Benchmark values suggested by the NRC include: grass hay, 55% TDN and 10% crude protein (CP); mature alfalfa hay, 50% TDN and 14% CP.
A 1,000-pound, yearling heifer requires approximately the same amount of TDN and CP as a 1,300-pound mature cow. If possible. first-calf heifers should be fed apart from the cow herd because they typically will not compete well with mature cows. Cows in good condition at calving will generally cycle well at 60 days post-calving whether they lose or gain weight after calving. However, cows that calve in moderate or thin condition will usually cycle and conceive late. Many will have difficulty maintaining a 12-month calving interval.
Increasing alfalfa in a beef cow diet can be an excellent way to meet increasing protein requirements. This can be accomplished by feeding hay with a higher percent alfalfa hay, feeding a portion of forage as alfalfa or feeding the desired amount of alfalfa once a week.
