Nutritional support Flashcards
List the 5 reasons for utilising feeding plans.
To:
1. Deliver daily calorie requirement (DER + RER)
2. Improve recovery time
3. Ensure a nutritionally balanced diet to maintain optimuum bodily functions
4. Prevent or correct nuritional imbalances
5. Prevent the body from catabolizing lean body mass
7..
What information do you need in order to create a feeding plan?
What the:
* Normal feeding habits are (how often, amount etc, amount)
* Feeding routine is
* What diet is being provided
* Known allergies are
* BCS
* MCS
* VS diet diagnosis of type of diet + approval
What are the 5 steps to creating a feeding plan?
- Ascertain what the normal feeding habits are; including routine + diet
- Find out from the owner any known allergies or medically relevant reasons to why their diet is being given
- Discuss with VS in charge, what diet should be offered - relevant to clinical condition
- Share BCS + MCS with VS - as they are subjective
- Record on patient’s client record + hospitilisation sheet the diet that must be fed + a list. of alternative foods that could be fed - if unavaliable
4 - Note, that there may be clinically relevant reasons for a high or low BCS or MCS score, which may alter the DCR (Daily Calorie Requirement)
What is the BCS for rabbits called?
Rabbit Size-0-Meter
What is the minimum and maximum score range on the Rabbit Size-0-Meter?
- Minimum = 1
(Underweight) - Maximum = 5
(overweight)
What is the ideal score on the Rabbit Size-0-Meter?
RS0M = Rabbit Size-0-Meter
3
What percentage under ideal body weight is a rabbit, with a score of 1, on the RS0M?
BW = Body Weight
> 20% below ideal BW

What does the MCS focus on?
Muscle mass
Can an obese patient have a low MCS?
Yes, this does not mean they’re healthy though
Does a healthy BCS mean the patient will have a healthy MCS?
No
Think of whether they are fast or slow..
What are the most common 2 types of conditions that tend to present with muscle loss?
Acute disease + Chronic disease
What is the difference between Sarcopenia + Cachexia?
Sarcopenia defined as the loss of muscle mass and function associated with aging. (Unrelated to disease)
Cachexia defined as weight loss due to an underlying illness, are muscle wasting disorders. (Associated to disease + morbidity)
Name a few causes of cachexia, in relation to chronic disease

What is the Resting Energy Requirement (RER) formula?
RER = BW (kg) x 30 + 70
What does the RER formula work out?
The calories required in a 24hr period, to maintain bodily functions, when the animal is resting
Work out the RER for a 25kg Border Collie
RER = BW (kg) x 30 + 70
RER = 25kg x 30 + 70
= 820 kcals p/24hrs
Work out the RER for a 5kg DSH
DSH = Domestic Short Hair
RER = BW (kg) x 30 + 70
RER = 5kg x 30 + 70
= 220 kcals p/24hrs
Work out the RER for a 2kg Tea-cup Yorkie
RER = BW (kg) x 30 + 70
RER = 2kg x 30 + 70
= 130 kcals p/24hrs
What does DER stand for?
Daily
Energy
Requirements
State a few factors that affect RER
- Age - growing patients require greater calories
- Working animals (Spingers, collies etc) require more kcals for their high-active lifestyle
- Pregnant or lactating patientes

Work out the RER for a 2m old Terrier Cross breed, weighing 2.5kg
-
RER = BW (kg) x 30 + 70
= RER = 2.5kg x 30 + 70
= 145 kcals p/24hr
2.DER = 2m = In ‘Up to 4m old’ bracket = DER x 3
= RER x 3
= 145 x 3
= 435 kcals p/24hr
Work out the RER for a 1 yr old Cocker Spaniel, weighing 9kg
-
RER = BW (kg) x 30 + 70
= RER = 9kg x 30 + 70
= 340 kcals p/24hr
2.DER = 1 yr = In ‘Medium/Heavy work’ bracket = DER x 4
= RER x 4
= 340 x 4
= 1360 kcals p/24hr
What are the 10 pieces of information you must ascertain to calculate how many grams p/24hr can be given to the patient?
- Patient history
- Diet
- Normal feeing habits
- Relevant medical + surgical conditions
- BCS
- MCS
- Weight
- Discussed with VS in charge, what diet diagnosis, RER calculations
- Calculate kcal p/24hrs
- Calculate grams p/24hrs
How do you work out how many grams the patient requires to be fed per day?
By finding out what the kcal/g of the selected diet is + divide it by the kcals p/24hrs
How to work out the kcal per gram of dry food.
Using the example below.
Dry food tin = 3756kcals per kg = 376kcals per 100g
Convert Kg > g.
= 3756kcal p/g (divided by) 100
= 3.76 kcal p/gram
Because there is 1000g in a kg
How to work out the kcal per gram of wet food.
Using the example below.
Wet food can = 286kcals per 354 g can
Start by converting Kg > g.
= kcals p/gram (divided by) amount in the can
= 286kcal p/g (divided by) 354g
= 0.8 kcal p/gram
How do you work out how many grams a day the patient needs from that tin of wet or dry food?
RER (divided by) kcals p/gram
= g p/24hrs (divided by) meals to be given per day
= g per feed
Work out how many grams a day does a 25kg border collie, on a selected diet of dry Hills z/d, with 3.6kcals per gram
Hills z/d = z/d = diet name
Work out RER
RER = BW (kg) x 30 + 70
= RER = 25kg x 30 + 70
= 820kcals p/24hrs
**Ascertain how many kcals in p/g of diet **
= Diet kcals p/g = 3.6kcal
Work out how many kcals p/24hrs
RER (Divided by) kcals p/g = diet kcals p/24hrs
= 830kcals p/g (divided by) 3.6 kcals p/gram
= 227.8g p/24hrs
**Meals required per day = usually 4 **but can be 6 (in paediatric patients)
Find kcals p/g p/24hrs (divided by) meals required per day = g per meal
= 227.8g p/24hrs (divided by) 4 meals
= 228.56.95g per feed
