Pet Food Plant KPIs: Benchmarks for Kibble Lines and How to Improve Them
Extruder OEE, moisture control, kibble durability, yield, giveaway, run rate, changeover and palatability testing on a kibble line: how to measure each, what moves it, and which figures have a cited source.
Use these benchmarks as reference points for spotting a gap worth investigating on a kibble line, not as targets to copy. Your own trend, measured the same way week after week, says more about your extruder, dryer and bagger than any single published figure.
Every figure shows its basis. A superscript number links to a public source in the Sources list, and the sentence states that source's context, such as its year, population or test method. A figure marked no cited source is kept exactly as originally published because no public source stating it has been verified, so treat it as illustrative.

Pet food and kibble line KPI benchmarks at a glance
Words in parentheses give each figure's own framing. The cited OEE figures are cross-industry, not pet food studies, and none of them states the pet food ranges. The commercial canine diet durability figures are unpublished data cited by the thesis, which does not name the test method behind them5.
Method: How the figures in this guide are sourced
A figure with a superscript number is stated by the cited source, listed under Sources with its publisher, location in the document and access date. A figure marked no cited source is kept exactly as originally published because no public source stating it has been verified. It is illustrative, not measured industry data. Worked examples show arithmetic only and are not benchmarks.
Extrusion line OEE
Overall equipment effectiveness (OEE) on the extrusion line is the headline number. Typical dry pet food plants run 55 to 68 percent OEE no cited source.
No public pet food OEE survey was found, but cross-industry figures give context. OEE vendor Vorne observes that most manufacturing companies have OEE scores closer to 60 percent1, and a Chalmers University thesis found machine OEE in Swedish manufacturing companies averaged 51.5 percent2.
Well run lines hold 72 to 80 percent no cited source. World-class sustained operation reaches 85 percent, the cross-industry world-class figure from Seiichi Nakajima's work on total productive maintenance3, 1.
Watch the three factors separately. For example, 70 percent availability, about 98 percent performance and 90 percent quality multiply to roughly 62 percent OEE, so a plant can post 62 percent from 90 percent quality and only 70 percent availability.
The usual availability killer is changeovers and dryer trips. The fastest OEE gains come from reducing unplanned stops below 6 percent of scheduled time no cited source.
How to measure
Multiply availability, performance, and quality against scheduled production time.
Chart the three factors separately as well as their product.
Log changeovers and dryer trips as their own stop codes.
Moisture control is the KPI that pays for itself, because water is free weight you are legally allowed to sell. Target finished moisture consistency with a standard deviation under 0.5 percent and a coefficient of variation below 1.5 percent around your setpoint no cited source.
Published figures for finished moisture differ, so choose your setpoint from your own shelf-life data. The Pet Food Institute, a U.S. trade association, says dry pet food typically has a 10 to 12 percent moisture content4. A 2008 Wageningen University thesis says dry extruded dog and cat diets must be dried to 60 to 90 g/kg, or 6 to 9 percent5.
Typical plants run a CV of 2.5 to 4 percent and dry defensively to 8 percent to avoid mold risk, giving away 1 to 2 points of yield no cited source.
For example, tightening moisture CV from 3 percent to 1.2 percent lets you hold 9.5 percent safely, and each recovered point of moisture is roughly 1 percent more saleable tonnes.
How to measure
Sample finished moisture at a fixed frequency after the dryer and cooler.
Report the standard deviation and coefficient of variation around the setpoint, not only the mean.
Chart it per shift and per product.
What moves it
Dryer and cooler control that narrows the spread.
Stable preconditioner steam and in-barrel moisture upstream.
Raising the setpoint only after the spread is under control.
Pellet or kibble durability is the quality proxy customers feel first. World-class dog kibble holds a durability index at or above 97 percent no cited source with fines under 2 percent no cited source.
Measured data show a wide spread. In unpublished data cited by the 2008 Wageningen thesis, commercial canine diets ranged from 78.7 to 99.8 percent durability, with a mean of 87.3 percent5. The same thesis notes that a kibble durability index of 90 percent or more is generally used as a target in the feed industry5.
Typical operations run 5 to 7 percent fines no cited source. Durability values depend on the test method, so name the tester whenever you compare figures.
The levers are die design, binder or starch level, and cooling profile. Gentler cooling and 1 to 2 points more in-barrel moisture at the die usually add 2 to 3 durability points no cited source, cutting dust complaints and rework in one move.
How to measure
Run the durability test every shift with the same tester and method.
Report fines separately from the durability index.
Trend durability against extruder specific mechanical energy (SME) and cooling rate.
First-pass yield ties the physical KPIs to money. Benchmark good-product yield at 96 to 98 percent of raw material input for mature lines no cited source; typical plants lose 4 to 7 percent to fines, transitions, and off spec no cited source.
Break the loss into buckets and attack the biggest. Startup and shutdown transitions often account for 1.5 to 3 percent alone on lines that run many short SKUs no cited source, and consolidating from twelve daily changeovers to six can recover a full point of yield no cited source.
Track rework rate separately and cap it near 6 percent no cited source, since high rework masks a process that is not actually in control.
How to measure
Divide good product out by raw material in.
Assign every loss to a bucket: fines, transitions, or off spec.
Weight giveaway is a standalone KPI worth a dedicated chart. World-class bagging holds average fill within 0.4 to 0.6 percent above the labeled minimum no cited source; typical lines give away 1.2 to 2 percent no cited source because the checkweigher feedback loop is loose or the filler drifts.
In the United States the label normally declares a net quantity, not a minimum. NIST Handbook 133 states that, in general, the average net quantity of packages in a lot must at least equal the quantity declared on the label8.
For example, cutting giveaway from 1.5 percent to 0.5 percent on a 5,000 tonne year returns about 50 tonnes of product to inventory. It costs nothing but tighter filler control and more frequent scale verification.
How to measure
Compare checkweigher averages with the declared net quantity for every bag size.
Chart the fill distribution, not only the average.
Throughput rate against nameplate tells you whether the asset is earning. Benchmark sustained extruder run rate at 88 to 95 percent of nameplate for the running product no cited source; typical plants average 75 to 85 percent no cited source because of feed rate hunting and moisture instability.
Do not confuse rate with OEE. For example, a line can hit 92 percent rate while running and still post about 60 percent OEE if it only runs 65 percent of the schedule, since 0.92 x 0.65 = 0.598.
Improve rate by stabilizing preconditioner steam and in-barrel moisture. Then the operator stops backing off feed to chase a wandering motor load.
How to measure
Divide sustained run rate by nameplate for the product running.
Measure it only while the line runs, separately from OEE.
Changeover and sanitation time gate flexibility, especially with allergen segregation. Benchmark a dry flush formula changeover at 25 to 45 minutes no cited source and a full wet allergen clean at 2.5 to 4 hours no cited source.
Laggard plants take 6 hours on a wet clean no cited source because sequencing and kit staging are ad hoc. Reduce the count of full cleans by sequencing SKUs from least to most restrictive allergen, and pre-stage cleaning kits at each transfer point.
For example, moving from eight full cleans a week to three removes five cleans; at 3 to 5 hours each, that adds 15 to 25 production hours, often worth more than any single rate improvement.
How to measure
Time dry flushes and wet cleans separately.
Count full cleans per week.
Record the allergen sequence that forced each full clean.
What moves it
Sequencing SKUs from least to most restrictive allergen.
Palatability testing is the KPI most plants under-resource until a product fails at the bowl. Benchmark your panel capacity against launch cadence.
Two-bowl preference tests need a defined panel. Most research groups have moved to feeding 20 animals for 2 or 4 days, according to a 2015 review in Animals6, and a 2024 review in the Journal of Food Science says the sample typically consists of 30 trained pets7.
World-class R and D groups keep test turnaround under 3 weeks per formula iteration no cited source; typical groups run 5 to 8 weeks no cited source and become the bottleneck on new business.
How to measure
Track queue time per formula, not just pass rate.
Convert the formula pipeline into required panel days.
Write one definition per KPI and keep it fixed, including the durability test method.
Chart OEE factors, moisture spread, durability and giveaway per shift.
Collect several months of data before you set a target.
Compare against your own trend first and published ranges second.
Record what changed in the process whenever a KPI moves.
