Extract

Data are presented concerning the efficiency of growth of Specific-Pathogen-Free Large White boars on individual performance test. Various aspects of growth rate, backfat thickness and food conversion are compared.

It is suggested that tests should be shortened by starting later, rather than finishing earlier.

Some support is given to the theory that one type of pig may not be suitable, from the point of view of efficiency of growth, for supplying the full range of carcass weights in current demand.
