Five Factors Considered When Planning Winter Forage Needs
Winter feeding requirements for cow-calf operations in Flori-
1) Number of cattle
da constitute 40-60 percent of the annual operating budget.
2) Average frame size
Often, cow-calf operators either over or under estimate their 3) Length of feeding period

5) Moisture content

Objectives: To raise producer awareness of the importance
of accurate estimations, to provide them with an improved
understanding of basic beef nutrition, and to enable them to
improve enterprise efficiency through calculated winter feed

results were significantly different than was expected (most
indicated that the calculated value was much larger than ex-

estimations typically under estimate herd requirements. The
effect of this error results in longer calving seasons, lower Winter Feeding Seminars Educate Producers

properly feeding their herd producers will see improved oper-
