Due to the intense
use of P fertilizers and livestock manure in modern day
agriculture, P has become an accelerator of fresh water
eutrophication, resulting in reduced oxygen availability
because of growth of algae and their decomposition. Recent
research indicates that dietary P management is a key strategy
to reduce P imports and accumulation on dairy farms. Thus,
a more precise formulation of dairy rations can lead to
substantial reduction in fecal P excretion without impairing
animal productivity. Some mathematical equations are
presented in order to estimate P excretion by dairy cows.
These equations would be very useful when developing
nutrient management programs. The objective of the study
was to make a brief commentary of the importance of P in the
body, understand that excess P can be an important threat to
surface waters, and to find the easiest and most economic
ways to reduce P excretion in dairy farm systems.
