This experiment was conducted as a follow-up to a previous experiment conducted\u00a0at the Prairie Swine Centre, which showed that pigs are able to achieve equivalent performance across diets of quite differing energy concentration. These results flew in the face of conventional wisdom,\u00a0which suggests that increasing dietary energy concentration, notably through the additional of fat, will\u00a0result in faster growth. This experiment was therefore conducted to re-evaluate this question, and\u00a0determine if increasing dietary energy concentration would improve pig performance. The experiment\u00a0was also designed to evaluate the impact of dietary energy concentration on carcass quality and on the\u00a0uniformity of growth.<\/p>\n
The results of this experiment, conducted on a commercial piggery, confirmed that higher energy diets
\ncan be successfully fed without an adverse effect of carcass quality. Despite the fact that the DE content
\nof the diet increased by 10%, there was no impact on backfat thickness, lean yield or carcass index.
\nIndeed, the higher energy diet tended to increase loin thickness.\u00a0Based on performance, carcass quality and financial return, the lower energy feeding program was once\u00a0again equal to, or superior to, the higher energy programs. In this experiment, the same energy level was\u00a0fed throughout; it would appear from the data that the most effective feeding program would be one that\u00a0employs higher energy levels in the growing and early finishing phases, perhaps up to 80 kg, with lower\u00a0energy levels used thereafter. This would take advantage of the improved growth on the higher energy\u00a0diets observed during the first 6 weeks in this experiment, and save money by lowering energy during the\u00a0final phase of growout, when energy did not elicit a growth response. Since 56% of the feed consumed\u00a0by pigs on this experiment occurred beyond 80 kg bodyweight, substantial savings could accrue from\u00a0feeding the lower energy diets after 80 kg.<\/p>\n","protected":false},"excerpt":{"rendered":"
