Protein and the price of virtue

There's nothing quite like the smoky scent of meat, chicken or fish being cooked over a charcoal brazier. Often, on the drive home from work in the evening, I pass through Kabalagala and Kansanga, where my nostrils are assailed by goat or chicken muchomo along the roadside. Deep fried whole tilapia is also widely on sale.

But there's something very unusual about the Ugandan market for animal protein. As a general rule, the price of animal protein ought to correlate closely with the cost of producing (or catching) that same protein. The main driver for the cost of production of animal body weight is, not surprisingly, the cost of feed inputs, and the industry generally measures this through the Feed Conversion Ratio. How many kilogrammes of animal feed is required in order to produce one kilogramme of animal body weight.

The smaller the animal, the lower its feed conversion ratio. This is not exactly surprising. Large adult mammals have to consume large quantities of feed simply to maintain their body weight. Think of elephants, for example. Apparently an adult elephant needs to eat an extraordinary 200 kgs of vegetable matter per day! Blood temperature also affects the amount of energy required by an animal in order to maintain weight. Hardly surprising, therefore, that fish are the most efficient converters, requiring a mere 1.7 kgs of feed per 1 kg of body weight, followed by chickens, at about 2.2 kgs, pigs at 4.1 kgs, with goats and cattle (like these splendid long-horned Ankole cows) coming in at about 10 kgs of feed per 1 kg of body weight.

And yet, in Uganda, beef is the cheapest meat on sale, followed by goat, pork, chicken and fish, in that order. Of course, there's an explanation: beef and goats forage for their food so it is, effectively, free, apart from the costs of herding and paying vet's bills. Pigs and chickens are often fed on household waste or home-blended feeds. And fish has become a premium product due to over-fishing in Lake Victoria. Nevertheless, it is hard to escape the conclusion that there is a considerable business opportunity for efficient livestock and poulty farming and aquaculture, and for a more professional animal feeds industry.

On a more humorous note, I was recently reminded (by a billboard in Muyenga advertising a local Ugandan magazine) of Proverbs 31, 10: "Who can find a virtuous woman? For her price is far above rubies."

The glamorous Kampala socialite and Beyonce-wannabe Zari Hussein (pictured) doesn't seem to subscribe to this ancient wisdom. According to a local magazine, Zari proclaims herself to be worth at least 300 cows, a reference to her lavish kwanjula (traditional wedding) in late 2011 where her bride-price reportedly included 300 head of cattle. Now, using the feed conversion ratio above, and assuming a conservative body weight of 500 kgs per cow, that comes to a total nutrition requirement of a colossal 1,500 MT in feed. The equivalent in chickens would have required a delivery of 75,000 chickens or 330 MT in feed. Yet it would have cost the groom a good deal more to supply 75,000 chickens than the 300 cows. Bizarre.

Either way, Zari's bride-price was still fairly inexpensive in comparison to the rubies of the proverb. Unlike most things in life, it remains impossible to place a price on virtue.
