fat % in feeds

[fcnubian]

How do you figure out the fat % of a feed you mix by hand?

I know how to get the protein % just not the fat...lol.

Thanks in advance!

I figure protein and fat the same way. Here's how I do it.

Get all the fat percentages for the ingredients you are using. (Like corn would be about 3% fat, oats 4% fat...)

Then multiply the fat percentage of that ingredient to how many pounds of the ingredient you are using. (If I use 10 lb. of corn I would multiply .03 x 10)

Do that for all your ingredients. Then add up the number for each ingredient you have (when you multiplied.)

Then divide what you added up by the total ammount of grain you have. That will give you the fat percentage.

Example: 33 lb of feed

Multiply

9 lb. ProVider 38 Dairy pellet 1% fat (.01 x 9 = .9)
10 lb. Corn 3% fat (.03 x 10= .3)
10 lb. Oats 4% fat (.04 x 10= .4)
2 lb. Beet Pulp .3% fat (.003 x 2= .006)
2 lb. BOSS 25% fat (.25 x 2= .5)

Add

.9 + .3 + .4 + .006 +.5 = 2.106

Divide

2.106 / 33 = .064

That makes this ration a 6.4% feed ration. To raise or lower the fat you can add and subtract BOSS.



( I also use this same formula to find out Protein, calcium, and phoshorous percentages.)

Thanks

I figured that was how it was done but wanted to ask and make sure.
