(1) During the first 50-postpartum d, infrared scanning enhanced detection of estrus when compared with standard dairyman-detection accuracy.
(2) It doesn't prove that your dairyman is watering the milk, but it is very strong circumstantial evidence.
(3) Controls consisted of cows seen in estrus by the dairyman and reported for insemination in the routine manner.
(4) The mean number of nonpregnant days for all 700 cows decreased from 120 to 98 days, resulting in approximately $46,000 of increased income for the dairyman or approximately a 4 to 1 return on investment in veterinary service.
(5) At each dairyman's option normal cows with a low porbe reading were inseminated.
(6) If only those samples collected and hand delivered by the dairyman within 1 day of collection were compared to a like subset of samples collected and hand delivered by veterinarians, no statistically significant differences in milk sample contamination rate (MSCR) were found.
(7) There were interactions between the sample source (veterinarian vs dairyman), delivery method, and time between sample collection and arrival at the laboratory.
(8) The dairy practitioner is the best source of information on medication that the dairyman has.
