A total of 75 weaned pigs [7.06 ± 0.18 kg of average body weight (BW); 28 day old] were randomly allotted to 3 dietary treatments in a randomized complete block design (blocks = BW and sex): a diet based on corn and soybean meal to meet the requirement of crude protein (CP) as a positive control (PC; CP = 24.49%), a low protein diet as a negative control (NC; CP = 22.51%), and NC + 0.02% PR.

Blood, feces, ileal digesta, and ileum samples were collected from randomly selected two pigs in each pen on respective time points. Measurements were growth performance, apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of dry matter (DM), CP, and energy, frequency of diarrhea, packed cell volume (PCV), and ileal morphology of weaned pigs. Pigs fed PC and PR had higher (p < 0.05) final BW, average daily gain (ADG), and gain to feed ratio (G:F) during overall experimental period than those fed NC. Pigs fed PC and PR had higher (p < 0.05) AID or ATTD of DM, CP, or energy than those fed NC. Moreover, pigs fed PR had higher ratio between villus height and crypt depth (p < 0.05) and number of goblet cells (p < 0.05) than those fed NC. Addition of PR decreased (p < 0.05) frequency of diarrhea for the first two weeks after weaning compared with PC and NC. In addition, pigs fed PR had lower (p < 0.05) PCV on d 14 after weaning than those fed PC and NC. In conclusion, addition of PR in nursery diets with a low protein level significantly improved growth performance, nutrient digestibility, and intestinal morphology of weaned pigs.http://www.ejast.org/archive/view_article?pid=jast-62-1-21growth performanceintestinal morphologynutrient digestibilityproteaseweaned pigs |

description |
This study was conducted to evaluate effects of dietary protease (PR) on growth
performance, nutrient digestibility, and intestinal morphology of weaned pigs. A
total of 75 weaned pigs [7.06 ± 0.18 kg of average body weight (BW); 28
day old] were randomly allotted to 3 dietary treatments in a randomized complete
block design (blocks = BW and sex): a diet based on corn and soybean meal to
meet the requirement of crude protein (CP) as a positive control (PC; CP =
24.49%), a low protein diet as a negative control (NC; CP = 22.51%), and NC +
0.02% PR. The PR used in this study was a commercial product containing 75,000
protease units/g derived from Nocardiopsis prasina produced in
Bacillus licheniformis. Pigs were fed the dietary
treatments for 6 weeks and the diets containing 0.2% chromic oxide for the last
week of this study. Blood, feces, ileal digesta, and ileum samples were
collected from randomly selected two pigs in each pen on respective time points.
Measurements were growth performance, apparent ileal digestibility (AID) and
apparent total tract digestibility (ATTD) of dry matter (DM), CP, and energy,
frequency of diarrhea, packed cell volume (PCV), and ileal morphology of weaned
pigs. Pigs fed PC and PR had higher (p < 0.05) final BW,
average daily gain (ADG), and gain to feed ratio (G:F) during overall
experimental period than those fed NC. Pigs fed PC and PR had higher
(p < 0.05) AID or ATTD of DM, CP, or energy than
those fed NC. Moreover, pigs fed PR had higher ratio between villus height and
crypt depth (p < 0.05) and number of goblet cells
(p < 0.05) than those fed NC. Addition of PR
decreased (p < 0.05) frequency of diarrhea for the first
two weeks after weaning compared with PC and NC. In addition, pigs fed PR had
lower (p < 0.05) PCV on d 14 after weaning than those
fed PC and NC. In conclusion, addition of PR in nursery diets with a low protein
level significantly improved growth performance, nutrient digestibility, and
intestinal morphology of weaned pigs. |
