Description: The purpose of this study was to measure the effect of lowering crude protein (CP) level in the starter piglet diet on animal performance, slurry production and ammonia emissions during the post-weaning (PW) period. The study was performed at the Cr?com experimental station (Brittany, France) with two batches of 196 piglets. For each batch, 2 x 98 piglets received, respectively, a standard starter feed (CP = 180 g/kg) or a low-CP starter feed (CP = 166 g/kg). A batch ? diet interaction was found for final body weight and average daily gain, with lower values for the low-CP diet in batch 2 (P < 0.05), whereas no difference was found in batch 1 during the PW period. Moreover, diet had no effect on feed efficiency during the PW period. Less water consumption, slurry volume and ammonia in the air were measured with the low-CP diet. Finally, ammonia emission was reduced by 16% with the low-CP diet compared to the standard diet. Use of a low-CP diet is thus a simple and effective solution to improve animal welfare and farmer well-being, as well as to meet environmental regulations.
