Abstract
The present disclosure provides methods and systems for optimizing a cost efficiency or a nitrogen-use efficiency (NUE) for a feeding regimen of a herd of interest of milk-producing animals, for monitoring a urinary urea-N excretion (UUNE) for a herd of interest of milk-producing animals, and for monitoring a NUE for a herd of interest of milk-producing animals. The methods include use of a milk urea-N yield (MUNY) value or a ratio of MUNY to a protein yield (PY) in milk produced by the herd of interest.
Claims10
A method for feeding a herd of interest of milk-producing animals, the method comprising:
- a) measuring from a herd of milk-producing animals to produce an observation data set comprising an amount of milk produced by the herd of interest on an observation date (MPO), a concentration of urea-N in milk produced by the herd of interest on the observation date (MUNO), a protein yield in milk produced by the herd of interest on the observation date (PYO), and a percent dietary crude protein in feedstock consumed by the herd of interest on the observation date or a date one to seven days before the observation date (CPO) on a dry matter basis;
- b) calculating a ratio (MUNYO/PYO) of a milk urea-N yield by the herd of interest on the observation date (MUNYO) to the PYO, wherein the MUNYO is the MUNO divided by the MPO;
- c) defining an optimal target ratio (MUNYT/PYT);
- d) generating a report indicating use of a first feedstock if the MUNYO/PYO is less than the MUNYT/PYT or indicating use of a second feedstock if the MUNYO/PYO is greater than the MUNYT/PYT, wherein the first and second feedstocks differ from one another;
- and
- e) feeding the herd of interest on one or more days after the observation date with the first or second feedstock indicated by the report.
