Nutrition
• Nutrition is the science of the interaction of
a nutrient with some part of a living
organism to promote some kind of optimal
performance and or function.
• It is the mechanical and chemical processes
of digestion and absorption of ingested
nutrients.
What does this mean to you?
• It is your responsibility as
veterinary technicians to educate
clients about proper nutrition,
frequency of feedings, what brands
of food are better than others, and
discussing weight management
regimens.
Nutritional Research
• Has greatly enhanced our understanding of
what companion animals require in a
balanced diet.
• Commercial diets are now formulated to
help prevent nutritional deficiencies, boost
the immune system, improve cognitive
health, and help slow the aging process.
Nutritional Support
• In times of illness and injury, nutritional
support is of great importance as the animal
will be dependent upon you for it’s
nutritional intake.
• Failure to recognize or address a patient’s
metabolic needs may have negative
consequences and may adversely affect
patient outcome.
Terminology
• Nutrient: Is any constituent of food that is ingested
to support life.
• Clinical Nutrition: is the application of nutrition
pertaining to actual observations and treatment of
patients.
• Digestible: the proportion of nutrients available
for absorption from the gastro-intestinal tract.
• Bioavailable: the amount of a nutrient absorbed
from the GI into the bloodstream in a form that the
body can use.
Overview of Nutritional Objectives
and Principals
• Our overall goal for companion animals is to
maximize the length and quality of the animal’s
life by reducing nutritional risk factors. We do this
by feeding the proper food for each life stage
requirement of the animal.
• Whereas in food animals, our main goal is to
encourage weight gain rapidly and not necessarily
focus on longevity.
Requirements for Maintenance
• Nutrients that prevent any loss or gain in
body weight. These balanced nutrients
provide the following:
1) Heat to maintain body temperature
2) Energy for internal work (heart rate and
respiration)
3) Energy for minimal movement
4) Energy/nutrients for repair of body
tissues
Influences on Maintenance
Requirements
• There are numerous influences on
maintenance requirements. These influences
are broken down into two categories:
»External Factors
»Internal Factors
External Factors
•
•
•
•
Activity
Weather
Health
Stress
Internal Factors
• Body size: small toy breeds required a
lower daily requirement than giant breeds
• Age: young animals consume more per unit
of body weight and utilize nutrients more
efficiently. Young animals require more
vitamins, minerals, protein and energy and
are more susceptible to nutritional
deficiencies.

Internal Factors
• Temperament: nervous, active breeds have higher
nutritional requirement.
• Productivity: the “couch potato” requires less than
the working dog.
• Lactation: the animal’s requirements do not
increase until late gestation (gestation lasts 59-63
days) animals should be fed maintenance levels
during the first part of gestation. This will prevent
un-required weight gain which can predispose
them to dystocias (difficult to impossible deliveries)
or musculoskeletal problems.
These are the Six basic
classes of nutrients that
are important for life
sustenance.
