1994
Abstract The objectives of this 24-herd, demonstration project of integrated problem solving and extension advising were 1) to evaluate dairy production management practices, 2) to formulate recommendations for guiding producers to correct management deficiencies, and 3) to measure the rate of practice adoption. Management evaluations focused on herd nutrition and forage crops, mastitis control and milking equipment, reproduction, and herd health. Sixtyeight management practices or milking equipment components were evaluated on each farm. A total of 216 recommendations were made in nutrition and forage crops as follows: calf and heifer management, 89; forage crops, 73; dry cows, 26; lactating cows, 19; and general, 9. The least adopted suggestions for nutrition and crops were for forage crop management. A total of 283 recommendations were made in mastitis management or milking equipment as follows: milking practices, 90; milking equipment, 90; general mastitis control, 61; environment, 32; calf management, 9; and stray voltage, 1. Producers most resisted updating and maintaining milking equipment within the milking management area. Detection of estrus was the focus of reproductive management advising. A total of 80 practices were recommended as follows: one person responsible, 24; specific location, 24; specific time, 24; and regular veterinary visits, 10. Designation of a specific site was the least adopted of these recommendations. Overall, 419 of 581, or 72%, of all recommendations were adopted.
