100 Mitigation of oxidative stress to improve range cow grazing distribution Open
The objective was to reduce oxidative stress (OS) and improve grazing distribution with an injectable trace mineral (ITM; 1mL/90kg MultiMin90). Mature cows (2021: n=35; 2022: n=34) were classified by residual feed intake (RFI) as inefficie…

The effect of bone and analytical methods on the assessment of bone mineralization response to dietary phosphorus, phytase, and vitamin D in nursery pigs Open
A total of 360 pigs (DNA 600 × 241, DNA; initially 11.9 ± 0.56 kg) were used in a 28-d trial to evaluate the effects of different bones and analytical methods on the assessment of bone mineralization response to dietary P, vitamin D, and p…

Enteropathy and bone marrow hypoplasia associated with presumptive albendazole toxicosis in a juvenile Boer goat Open
Albendazole is a widely used anthelmintic drug that is labeled for the treatment of specific nematodes and flukes in ruminants. Albendazole is approved for the treatment of liver flukes in goats (10 mg/kg PO for a single dose), but is comm…

Inductively coupled plasma mass spectrometry determination of hepatic copper, manganese, selenium, and zinc concentrations in relation to sample amount and storage duration Open
Trace mineral status is a critical component of bovine health. Impairment of physiological processes, caused by trace mineral toxicities or deficiencies, can be potential underlying factors of disease. Historically, the status of critical …

Comparison of trace mineral concentrations between liver biopsies of different sizes and durations of storage by inductively coupled plasma mass spectrometry Open
Consequential adverse health effects in cattle may occur as a result of impaired physiological processes brought on by trace mineral (TM) deficiencies and toxicities. Small amounts of TM are necessary to facilitate these processes, but ina…
