This will help you with the RC diets...

There are product info sheets for each diet. Never looked at their website before, could be useful being that we're a royal canin practice!

Thanks! If you have any ideas for what to include please let me know. I need to find out the kcals/g now for all the popular vet diets + estimation of it for popular pet foods too! That will be fun

Wow that's fab! Far too technical for me to work out how on earth you did it!

Hi, I have uploaded what I am working on to my profile. I want to make it into a one-stop calculation shop for nurses. Once its finished I thought I would just upload it for free access to all. Would you have a look/play and it you want to get involved...

the illness factors are where the overfeeding causes problems

Fab.

Re: energy calculations

Nick Shackleton — Sun, 04 Oct 2009 21:21:39 GMT

ignore the illness factors and just use the calculations above is how I read it

Re: energy calculations

Louise B — Sun, 04 Oct 2009 21:19:20 GMT

Thanks! If the book is suggesting a more conservative estimate are they recommending just feeding RER to hospitalised patients or how are they suggesting making adjustments?

Is this for cats & dogs?

I've reread and yeah no extra calculations for feline patients so I'm guessing so........

Re: energy calculations

Taken from the NEW BSAVA Manual of Advanced Vet Nursing:

RER (resting energy requirement) = 70 x (BW x 0.75) (30kg plus)

(30 x BW) + 70 (2 - 30kg)

Traditionally the RER was then multiplied by an illness factor between 1.0 and 2.0 dependant of the type of illness being treated to account for increases in metabolism associated with different conditions. Recently, there has been less emphasis on these subjective illness factors and current recommendations are to use more conservative energy estimates to avoid overfeeding. overfeeding can result in metabolic and gastrointestinal complications, hepatic dysfunction, increased carbon dioxide and weakened respiratory muscles.

If are planning of using this calculation for enteral feeding remember to reduce the first days feed by 50% and no food should be put down the tube for the 1st 24hrs.

I can't seem to find it

BER:

30 x BW + 70

MER

BER X 1.1

Illness factors aren't really used now, and depending on what you read, the calculation can vary between animals under 5kg and above!
