Pollution of waters resulting from phosphorus (P) runoff from agricultural land receiving long-term manure application is one of the most serious threats to water quality in many regions of the world. Of various approaches to alleviate the problem, reducing P surplus on animal farms through optimizing P intake and minimizing P excretion in manure offers a great opportunity. Here, we present a fecal P test method that has the potential to identify over-feeding of P in dairy cattle.

- Manure management based on nitrogen (N) needs can result in an excess of phosphorus (P) in the soil, contributing to environmental issues like eutrophication.
- Research compared N- vs. P-based manure applications on crop nutrient uptake, leaching, and soil P accumulation, finding that both application types provided similar crop nutrient support and leaching losses.
- However, the N-based treatment significantly increased P levels in the top 5 cm of soil, raising concerns about potential off-field P movement and environmental risks.
We retrospectively reviewed the cases of 15 foals and adult horses in which vancomycin was used, alone or in combination with an aminoglycoside, to treat methicillin-resistant staphylococcal and enterococcal infections. Signalment, presenting complaint, history (including history of treatment for the current complaint), results of bacterial culture and antimicrobial susceptibility testing, treatment, and outcome were reviewed. The average vancomycin dosage was 7.
