    Nutrition help?

    Hi guys not sure where to put this, but here goes!

    One of my subjects at college this year is nutrition, and my current assignment is about finding exact nutritional value/content of foods for a specific species. I, of course, have chosen horses

    My list of feeds is: seed hay, meadow hay, alfalfa chaff, bran, rolled barley, rolled oats, sugar beet, maize, cubes/nuts, linseed and wheat.

    Firstly, have I missed any out?

    And secondly (my main question) can anyone help me find the nutritional content? I need exact percentages/numbers for nutrients, eg 23% fibre and 12% fat. Do you think it would be best to go on manufacturers websites? If so, which ones?

    Thanks in advance for your help

    There's a great website, Equi-Analytical, that lists averages for most feed products. The problem I see is you need to find a similar site for products grown in the UK as local varieties, soil types and harvest practices can greatly impact the nutritional content.

    Specify what type of seed hay as they vary, you omited oil, pasture (that's a tough on to get good values on), there's other chaffs as well as plain old alfalfa (lucerne) hay.

    Thank you very much, I will take a look at that website.

    Edit: I just looked at the website, are the figures for percentages?

    Mostly. The far left tells you which values are % and as you go down to the trace minerals, those values are in ppm.

    Thanks. Could you also help me understand the five different columns? What does each one mean? More importantly, which column should I be looking at for nutrient percentage?

    The columns are labeled across the top.

    The first # is the # of samples they tested in the stated period.
    #2 is average
    #3 and 4 is the range of the samples tested
    #5 is standard deviation.

    Yes, I did see the labels but I need to know which one is relevant to me. I just need to know, for example how much proten is in oats. So which column do I look at?

    Are you not getting the complete screen?

    It starts L to R
    %, item tested, #sampled, average....

    Top to bottom would be
    % Dry matter
    % Protein
    % Lignin
    %.....

    So, do I read from the average column? Because if I add up the average column it does not make 100%.

    An example of what I am looking for: how much protein is in oats (as a whole, generally).

    12.7

    The averages are not going to add up to 100 because some of the components that have values show up in more than one place.

    When you get into carbs, different components are used over and over again to get a different profile of the product you're testing.
    NSC included sugars, fructan and starch.
    NSF included sugarsn fructan, starch and pectin.
    It can get very confusing very quickly.
