چکیده انگلیسی
Two experiments were conducted to examine the impact of dietary chicory on growth performance and odor of stored swine manure. In Exp. 1, 180 nursery pigs (10.6 ± 2 kg BW) were used in a 21-d experiment to evaluate the effects of replacing corn with chicory (0.5 to 10.0%) on pig performance. Overall, ADG increased (linear; P < 0.02) and ADFI tended to increase (P < 0.10) as the level of chicory increased in the diet. This effect was primarily due to numerically reduced performance when pigs were fed 0.5 or 1.0% chicory, with growth similar for pigs fed 0, 5, or 10%. In Exp. 2, 12 barrows (initially 59 ± 3 kg BW) were fed each of 4 experimental diets during four 10-d periods in a replicated 4 à 4 Latin square design to compare nutrient excretion and odor analysis of pigs fed 1) conventional corn-soybean meal diet; 2) diet formulated to minimize nutrient excretion; 3) diet 1 with 10% chicory; and 4) diet 2 with 10% chicory. Feces and urine were collected and measured for N, S, and P excretion and retention, as well as for odor and gas analyses. Pigs fed diets formulated to reduce nutrient excretion had less (P < 0.001) total N and P excretion and had simulated slurry with reduced (P < 0.001) pH and less (P < 0.001) S, N, and ammonia. The addition of chicory to the diet also reduced (P < 0.03) N and P excretion. In conclusion, chicory can be fed to pigs to reduce nutrient excretion while maintaining growth performance.
