Commonwealth contributions and British requirement of fruit.

Commonwealth contributions to the British diet 83 Thus, the supplies of bacon from Commonwealth sources are unlikely to increase as fast as supplies from home production, and supplies from European sources are already increasing. There is, however, one new possibility in the future, the production of pigs as part of the grain-sorghum scheme in Queensland. It is too soon as yet to estimate the potentialities of this scheme, but one word of caution is necessary. Sorghum can be used to replace only such foods as maize in the fattening of pigs. Adequate supplies of protein-containing foods for sows and weaners will, therefore, be the limiting factor in this form of pig production. The success of the scheme will thus depend upon one or both of two factors, the discovery of new supplies of feeding-stuffs containing animal protein, and the more efficient use of present supplies. There is no doubt that feeding-stuffs containing animal protein have been used very wastefully in the past and could be used far more efficiently in the future. The discovery of cheap sources of vitamin q2 also would help with the large-scale production of store pigs for fattening on sorghum.
