Dry Matter Determination Flashcards
how to compare foods w dfferent moisture levels
look at dry matter determinations (all ingredients except water)
how dry matter determination is done
weigh food, dry in oven, re-weigh
original weight- new weight= water lost
a 100g weighs 85 g after drying, what is the % moisture and % dry matter
15% moisture and 85%DM
if a dry food is 10% moisture it is __% DM
90%
smaller animals have ____ (increased or decreased) energy needs, why?
increased; bc fast metabolic rate
metabolic rate and energy needs increase in what physiologic conditions
pregnant, nursing, growing, working
why we should treat dogs of same litter as individuals
could have different fathers, may have different metabolic or absorption rates
what is meant by the “common sense approach” when feeding
adjust feed as needed by watching body condtion and hair coat
pros of ad lib feeding
easy, quieting effect in kennels, decreased coprophagy, allows less agressive animals to stay in group and eat
cons of ad lib feeding
may cause obesity, hard to recognize anorexia/ sickness
pros of small frequent meals (timed or restricted feeding)
better utilization, help w digestion or absorption problems (EPI, diabetes mellitus), help animals who require high energy intake (puppies, cold temp, heavy work, lactation)
most animals are ok to feed __mins 1x a day except…
10 minutes, large breed dogs (increased risk of Gastric dilation and volvulus GDV, stomach bloats up and twists)
formula for amount to feed an animal
animal’s caloric needs/ caloric density of food
digestible energy need for
small breed dogs <20#
medium-large 20-75#
giant >75#
small: 50 kcal/# per day
med-large: 35 kcal/# per day
giant: 30 kcal/# per day
energy obtained from what provides the most kcal/gram of digestible energy (carbs, fat, or protein)
fat (protein 2nd most)
