Comparing Feedstuffs Based Upon Protein and Energy

By Tracey Erickson

Livestock Decision Aid:
Feed comparison calculators available!

SDSU Extension recently updated the feed cost comparison calculator, which is one of the three calculators offered as part of its Livestock Decision Aid, which can be used on mobile and desktop devices. It is suggested to have a basic feedstuff analysis available when using the tool and to know the dry matter content of the feedstuff for an accurate comparison. However, if you prefer to do the calculations by hand, please refer to the formula and examples below.

Comparing Feeds:
Pricing feed 'protein' & 'energy' sources by hand

When producers decide to purchase feedstuffs to balance diets, the first question often asked is, “Do I need a source of energy or protein or both to economically balance the ration?” Next is evaluating what is on-hand for feedstuffs compared to what might need to be purchased. The final question then is “What might be the most economical feedstuff, if feed is to be purchased?”
Producers often classify feedstuffs into categories such as forages, grains, supplements, and minerals/vitamins. From these major categories we can decide what is needed to balance the diet. Is it protein, energy, or minerals/vitamins? In order to compare apples to apples you will need to look at the amount of each nutrient available on a dry matter basis so that an accurate cost comparison can be made for the desired nutrient. The following formulas allow you make this comparison when evaluating protein and energy in feedstuffs and their cost to the diet.

Drone Flight & Baling Success at Last!

After weeks of rain delays and frustration, we finally have a reason to smile — it’s hay time again at Ewetopia Farms! In today’s episode, we head out to the fields where Arnie is baling hay, and I attempt my second drone flight to capture it all from the air. The drone still had some hiccups, but I managed to get some aerial footage of the baling process.

Back at the farm, the work doesn’t stop. Arnie brings the bales home, and the next critical step begins — wrapping and stacking the bales to make haylage. This process is essential for preserving feed for our sheep and ensures they have nutritious forage in the months ahead.

It’s a good day on the farm — the sun is out, the drone is flying (sort of!), and we’re making progress. Join us for a satisfying and productive day that brings a long-awaited sigh of relief to this year’s challenging hay season.
