An estimate of the body weight of a sow is the first
important step to efficient feeding.
According to an animal scientist at a Kansas State University, the body
weight determines around 80% of the feed needs of a gestating
However, a precise estimation of each sow's weight is extremely
Hence, according the Mike Tokach, state leader of
K-State Research and Extension's animal science programs, swine specialists
within the university have developed a method to make the process easier for
Tokach stated further that a 'flank-to-flank'
measurement forms the basis for the estimation of a sow's weight. This
measurement enables a more accurate determination of daily feed amounts.
The university scientists have gone further by creating a cloth tape
with respective colour-coded sections, each of which corresponds to a certain
A 'flank-to-flank' measurement
involves measuring from immediately in front of the sow's back legs, over the
back of the sow to the point of the other flank.
Correct feed amounts
"Once the weight group is established, a
tool on the university's Department of Animal Sciences and Industry website can
be used to determine correct feed amounts", said Tokach.
