Rice: longstanding staple for

of new information about rice's
current and future utilization
and potential challenges.

Rice as a popular pet
food ingredient

Rice is a staple in many pet
food diets, even in the age
of grain-free demands from
customers. Luis2007, Dreamstime.com

In February 2004, the topic of
rice in pet foods was covered in this
column. What is new 14 years later?
For starters, rice, along with other
grains, has lost significant product share to nongrain carbohydrates like legume seeds (pulses)
and tubers. There has been some research
published that provides comparison between the
two. Plus, there is some controversy in human
foods regarding rice and its potential contamination with arsenic that has bled over into the pet
food trade. Read on for an update and summary

Rice remains a popular
ingredient in pet diets despite
the growing trend toward
grain-free offerings. Most of
the rice used comes under the
category of "brewers rice." This
nomenclature still confuses
some consumers. The brewing
industry requires perfect
seeds. Their broken, cracked or
blemished grains have been a
reasonable choice for pet foods
given we typically grind or flour
them before production. Despite
what some critics might purport,
this is not a low-quality waste product. Regardless, today more white or polished rice is being
purchased straight from grower co-ops to fulfill
the volume requirements. Thus, most rice used
in pet food is the same grade and quality as that
used in human foods.
Cooking rice improves starch digestibility to
near 100 percent and recent work re-substantiates
this. For example, Carciofi et al. (2008) reported
that brewers rice at 45 percent of the formula
was more completely digested than a comparable
level of corn, sorghum, lentil and peas when fed
