| description | The addition of dietary proteases (PRO) to weaner diets hydrolyzes soybean-based
anti-nutritive factors and improves weaned pig’s dietary digestibility
and growth performance. Therefore, this study explores the effects of PRO in a
lower crude protein (CP) level diet than that in a commercial diet on the growth
performance, nutrient digestibility, and intestinal morphology of weaned pigs. A
total of 90 weaned pigs were randomly assigned to 3 dietary treatments with 6
pigs per pen and 5 replicated pens per treatment using a randomized complete
block design (block = body weight [BW]): 1) a commercial weaner diet as a
positive control (PC; phase1 CP = 23.71%; phase2 CP: 22.36%), 2) lower CP diet
than PC as a negative control (NC; 0.61% less CP than PC), and 3) an NC diet
with 0.02% PRO. Pigs fed PC and PRO had higher (p <
0.05) final BW, average daily gain, and/or gain to feed ratio for the first
three weeks and the overall experimental period than NC. The PC and PRO groups
had greater (p < 0.05) apparent ileal digestibility of
dry matter, CP, and energy than the NC group. Moreover, pigs fed PC and PRO
increased (p < 0.05) apparent total tract digestibility
of CP compared with those fed NC. In addition, the PRO group had a higher number
of goblet cells than the PC and NC groups. However, pig fed PC and PRO increased
(p < 0.05) villus height and height to crypt depth
ratio in the ileum compared with those fed NC. In conclusion, PRO
supplementation in a commercial weaner diet with low CP levels improves growth
rate and nutrient digestibility by modulating the intestinal morphology of
weaned pigs. |
