Livestock Slaughter and Carcass Yield Calculator
Calculate carcass weight, dressing percentage, and retail cut yield from live animal weight for cattle, hogs, sheep, and goats.
The two-stage yield calculation
When you take an animal to slaughter, you don’t get the live weight as meat. Two stages of weight loss happen:
Stage 1 — Live to Hot Carcass: Dressing % = (Hot Carcass Weight ÷ Live Weight) × 100
The carcass is what remains after removing hide, head, feet, hooves, organs (offal), and blood. Some processors include kidneys; some don’t.
Stage 2 — Carcass to Retail Cuts: Retail Yield % = (Retail Pounds ÷ Carcass Weight) × 100
The carcass is further reduced when bones, excess fat trim, and processing waste are removed. A “boneless trim” finish reduces yield more than bone-in cuts.
Typical yields by species
| Species | Live → Carcass | Carcass → Retail | Live → Retail (combined) |
|---|---|---|---|
| Beef (grain-finished) | 62-65% | 62-65% | 39-42% |
| Beef (grass-finished) | 58-61% | 60-63% | 35-38% |
| Hog/Pig | 70-74% | 65-75% | 46-55% |
| Lamb/Sheep | 48-52% | 55-65% | 26-34% |
| Goat | 46-50% | 55-65% | 25-32% |
| Bison | 56-60% | 60-65% | 34-39% |
| Elk/Deer (field-dressed) | 70-75% | 60-65% | 42-49% |
| Wild boar | 65-68% | 65-70% | 42-48% |
| Rabbit | 50-55% | 75-80% | 38-44% |
| Chicken | 65-72% (carcass) | 88% (meat) | 57-63% |
| Turkey | 70-75% | 85% | 60-64% |
The big takeaway: a 1,200 lb steer yields only 480-510 lbs of retail meat — roughly 40% of live weight. Hogs are more efficient (around 50% retail yield) because they have less waste.
Why dressing percentage varies
Several factors push dressing percentage up or down:
- Body condition: Fatter animals have higher dressing percentage because internal fat counts as carcass weight even though it gets trimmed later. The retail yield (after trimming) is lower.
- Breed: Beef breeds (Angus, Hereford) dress higher than dairy breeds (Holstein cull cows). Hogs bred for meat dress higher than older “lard hogs.”
- Sex: Steers and heifers dress similarly. Intact bulls dress lower (less internal fat). Sows dress lower than barrows.
- Age: Younger animals dress higher. A finished steer at 18-22 months dresses ~63%; the same animal at 36 months might dress 58%.
- Gut fill: An animal weighed full of feed dresses lower than one fasted overnight. Industry practice is to weigh after a 12-24 hour fast for accurate comparisons.
- Feed type: Grain finishing adds internal fat and slightly raises dressing %. Grass finishing keeps animals leaner but more flavorful.
Hot vs cold carcass weight
Two carcass weights matter:
- Hot carcass weight (HCW): immediately post-slaughter, before refrigeration. This is the official “dressing weight.”
- Cold carcass weight: after 24-48 hours of chilling. Typically 2-3% lower due to moisture evaporation (“shrink”).
USDA grading and most pricing is based on hot carcass weight.
Cuts breakdown for beef
A typical 750 lb beef carcass breaks down approximately:
| Region | % of carcass | Typical retail products |
|---|---|---|
| Round (hindleg) | 25% | Steaks (top/bottom round), roasts, ground beef |
| Loin | 17% | T-bone, Porterhouse, NY strip, tenderloin/filet |
| Rib | 9% | Rib roast (prime rib), ribeye steaks |
| Chuck (shoulder) | 26% | Chuck roast, ground beef, short ribs |
| Brisket | 4% | Brisket roast, corned beef |
| Plate | 7% | Skirt steak, short ribs, ground |
| Flank | 4% | Flank steak, ground |
| Other (shank, fat, bone) | 8% | Ground/stew, soup bones, suet |
The premium cuts (loin, rib, tenderloin) are roughly 25% of carcass weight but generate 50%+ of total retail revenue. A whole-animal purchase from a farmer averages out the value — you’re paying the same per pound for ribeye and ground beef.
Cost comparison — whole animal vs grocery store
A typical small-farm beef purchase (2024):
| Item | Cost |
|---|---|
| 1,200 lb live steer purchased | $2,400 ($2.00/lb live) |
| Slaughter and cut/wrap fee | $700-$1,000 |
| Total cost | $3,100-$3,400 |
| Retail yield: ~480 lbs | |
| Effective $/lb retail | $6.50-$7.10/lb |
Compare to grocery prices (mix of cuts):
- Ground beef alone: $4-$6/lb
- Steaks: $10-$25/lb
- Roasts: $7-$15/lb
- Blended average: $9-$13/lb
So a whole animal saves 25-50% vs grocery prices, plus you get higher-quality grass-fed or pasture-raised meat. The downside is freezer space requirements (a 480 lb beef needs roughly 16 cubic feet of freezer).
Pork — the most efficient meat animal
Hogs dress at 70-74% and produce roughly 50% retail yield from live weight. A 280 lb market hog yields:
- Hot carcass: 200 lbs (71% dressing)
- Retail meat: 140 lbs
- Distribution: ~25% bacon/belly, 20% hams, 15% chops/loin, 15% shoulder, 25% ground/sausage
Pork has the highest meat-to-feed efficiency of common meat animals — one reason it’s the world’s most consumed meat (chicken now matches it).
Wild game yields
Hunters often field-dress (remove internal organs) before transport. Field-dressed weight is roughly equivalent to a low dressing percentage already done:
| Animal | Live (lbs) | Field-dressed (lbs) | Boneless meat (lbs) |
|---|---|---|---|
| White-tailed deer (buck) | 150-200 | 110-150 | 50-70 |
| Mule deer | 150-300 | 110-220 | 55-110 |
| Elk | 500-700 | 350-490 | 160-225 |
| Moose | 800-1,200 | 560-840 | 250-375 |
| Wild boar | 150-250 | 105-175 | 65-115 |
| Black bear | 200-400 | 140-280 | 70-160 |
| Turkey (wild) | 18-25 | 14-19 | 9-13 |
Wild game generally has higher protein, lower fat, and different flavor than farmed equivalents. Yield-per-pound calculations are similar but moisture and shrinkage rates differ.
Hanging time — aging the carcass
For beef and lamb, post-slaughter “aging” or “hanging” improves tenderness and flavor:
- Wet-aged (in vacuum bag): 7-21 days; preserves moisture; typical commercial standard
- Dry-aged (open-air at 34-38°F, 80-85% humidity): 21-90 days; loses 5-15% moisture; develops nutty flavor
- Hanging without aging: 1-3 days, just enough to firm up muscle
Dry aging beef for 28-42 days produces premium quality at the cost of significant shrinkage — a 750 lb carcass might lose 50-80 lbs to the dry-age process. Most farm-direct beef is wet-aged for 14-21 days.
Bottom line
Live weight is roughly 40% retail meat for beef, 50% for pork, 30% for lamb. Dressing percentage varies with breed, finish, and age. Whole-animal purchases from farmers save 25-50% vs grocery prices and provide better-quality meat, but require freezer space and bulk-purchase planning. Knowing your expected yield is essential for slaughter planning, pricing, and storage.
