Metrics
Final live weight of our pigs was never directly measured. Some sites suggest assuming 72% as a reasonable factor to convert live weight to hanging weight.
$$Hanging\ Weight = 72\% \times Live\ Weight$$
$$Live\ Weight = \frac{Hanging\ Weight}{72\%} = \frac{333\ lbs}{72\%} = 463\ lbs$$
Feed Cost per Pound
$$\frac{Total\ Feed\ Cost}{Total\ Feed\ Weight} = \frac{$557.32}{1400\ lbs} = $0.40\ per\ lb$$
Growth Rate
$$\frac{Live\ Weight}{Day \times Pig\ Count} = \frac{463\ lbs}{264\ days \times 2} = 0.88 \frac{lbs}{day}$$
Feed Conversion
$$\frac{Live\ Weight}{Feed\ Consumption} = \frac{463\ lbs}{1400\ lbs} = 0.40 \frac{lbs}{lb}$$
Processing Efficiency
Some sites recommend assuming the processed, take-home weight is roughly 65% of the hanging weight. Our actual realized processing efficiency was 57%.
$$0.65 \times 333\ lbs = 216.5\ potential\ lbs$$
$$\frac{Processed\ Weight}{Hanging\ Weight} = \frac{191\ lbs}{333\ lbs} = 57\%$$
$$\frac{Processed\ Weight}{Live\ Weight} = \frac{191\ lbs}{463\ lbs} = 41\%$$
Cost per Pound
- Direct Fixed Costs + Direct Variable Costs Only (ie, excludes freezer and straw)
$$\frac{Acquisition + Feed + Processing\ Costs}{Processed\ Weight} = Cost\ Per\ Processed\ Lb$$
$$\frac{$300.00 + $557.32 + $597.18}{191\ lbs} = \frac{$1454.50}{191\ lbs} = $7.62/lb$$
- Direct Fixed Costs + Direct Variable Costs Only, and excluding fee for smoking bacon and hocks
$$\frac{$300.00 + $557.32 + ($597.18 - $80.12)}{191\ lbs} = \frac{$1374.38}{191\ lbs} = $7.20/lb$$
