Extract

1. An experiment has been carried out using 64 pigs individually fed. They received a common ‘grower’ ration to 120 lb. live weight and were then divided into four groups. The ‘finisher’ rations contained 0, 2·5, 5 or 10% fat.

2. The rations containing more fat also had a higher protein content and the scales of feeding were so arranged that the pigs received the same daily intake of protein and ‘energy’.

3. The growth rate was slightly more rapid with the fat-supplemented diets and the carcass characteristics were not in any way impaired.

4. The efficiency of feed utilization (f.c.r.) improved considerably when fat was included in the ration: the f.c.r. was 3·93 in the absence of fat and 3·30 when the ration contained 10% added fat.
