The relentless development of machine guns and heavy artillery from the turn of the twentieth century raised the stakes of warfare in previously unimaginable ways. Just as there is a case to argue for a wider interpretation of margins, to reflect a product’s costs and value to the economy, there is also a case to be made for revising the criteria by which these items are judged to be of use. Agriculture brings together a number of inseparable variables just to survive, let alone be profitable, making complex trade-offs on the way. Take animals, for instance.
From conception to weaning, producers face a steady pull on their resources. In the case of pigs, there will be little prospect of selling from a new litter until the new arrivals can leave their mothers’ sides and feed independently. Once this milestone has been passed, options will become available for breeders to start earning from their young additions to the herd.
Animals that are to be raised for slaughter will have a target slaughter weight, somewhere around 100kg for pigs. Any heavier than that and the earning potential will drop steadily, as more feed is consumed and overheads rise. This brings us to a vital distinction that is easily overlooked. The pig producer will generally earn good money if the young animals wean successfully and go on to gain a hundred grams per day for the next six months. The market is front-end loaded and is run like clockwork down to the final 24 hours.
The opposite is true for draft animals, which earn their keep by staying alive and working to whatever age their breed can manage. The lead times are longer, the resources needed are far greater and users like the army are buying extensively for matched pairs and teams of six and more. It is quite clear that by sending draft animals off to battlefields, their value will be turned into an increasingly expensive remounting cycle of the military’s own making, in which the animals can perish within hours of arriving behind the lines. Even if brood mares are kept away from warfare, the early years of the twentieth century effectively wrote a series of blank cheques for the makers of commercial motors and trucks, to fill the haulage gap caused by modern warfare.
