Validity of purulent vaginal discharge, esterase, luminometry, and bacteriological tests for diagnosing uterine infection in dairy cows
The laboraty test was the most accurate for detecting uterine infections in dairy cows, but it is not practical on farms. A simpler method called luminometry may be a useful alternative.

Randomized controlled trial of intrauterine cephapirin treatment in cows of 100 days in milk or more affected by reproductive tract diseases
Treating dairy cows with reproductive diseases significantly improved their chances of getting pregnant again, compared to cows with these diseases that weren’t treated.

Identification of the optimal diagnostic criteria combination for reproductive tract diseases in dairy cows of 100 days in milk or more
Two on-farm tests allowed to detect reproductive diseases in dairy cows, showing that cows with these conditions had lower chances of becoming pregnant compared to healthy cows.

Is prolonged luteal phase a problem in lactating Holstein cows?
Many dairy cows had long reproductive cycles not solely due to pregnancy loss, suggesting that extended luteal phase might be a common but overlooked feature in high-producing cows.

Validity of luminometry and bacteriological tests for diagnosing intramammary infection at dry-off in dairy cows
Laboratory and on-farm bacterial tests were fairly accurate at detecting udder infections in dairy cows before dry-off. However, a simpler test called luminometry did not perform well and isn’t reliable for this purpose.

Validation of a leg-mounted pedometer for the measurement of steps in lactating Holstein cows
A pedometer for dairy cows accurately tracked steps overall, but it tended to overcount movement — especially walking — by picking up any leg motion, even when the cow wasn’t actually walking.

Herd-level associations between the proportion of elevated prepartum nonesterified fatty acid concentrations and postpartum diseases, reproduction, or culling on dairy farms
Dairy herds with more cows showing high blood levels of nonesterified fatty acid before calving were more likely to have cows develop reproductive diseases and to have poor success at first insemination.

Research Review: Barriers and psychological impacts of euthanasia on Canadian dairy farmers
Feb 1, 2023
Methods used by Canadian dairy farmers for on-farm euthanasia and the emotions associated with the decision and the practice of euthanasia
Most farmers use firearms for euthanasia, but some methods are considered unacceptable, especially for younger animals. Farm owners typically make the euthanasia decision, with limited involvement from veterinarians or training. Many farmers feel emotional or anxious about euthanizing animals, and there are gaps in proper methods, training, and decision-making guidelines.

Randomized controlled trial assessing the impact of a combined treatment of insulin glargine and propylene glycol on the resolution of hyperketonemia and milk production in postpartum dairy cows
Overall, the combined treatment of insulin and glycol didn’t speed up recovery of dairy cows with low blood sugar and high ketone. However, first lactation cows treated with this combination recovered faster and produced more milk compared to those given the standard treatment alone (glycol).
