Abstract
The objective of this study is to investigate the effect of dietary glucose
oxidase (GOx) supplementation on the reproductive performance, litter
performance, total tract digestibility, and blood profile of lactating sows fed
corn-wheat-based diet. A total of twenty multiparous sows (Landrace ×
Yorkshire) were allocated into one of four treatments with five replicates per
treatment. The dietary treatments were as follows: CON (Basal diet), GO1 (basal
diet + 200 U GOx/kg), GO2 (basal diet + 300 U GOx/kg), GO3 (basal diet + 400 U
Gox/kg). Dietary GOx supplementation did not affect lactating sow’s
reproduction performance as well as body weight, backfat thickness, and body
condition score during pre and post farrowing, and at weaning
(p > 0.05). However, after farrowing to weaning
period lactating sow’s fed GOx supplement has linearly
(p = 0.0196) decreased the bodyweight loss. While, there
were no effects (p > 0.05) observed on sows backfat
thickness loss, average daily feed intake, and estrus interval among treatment
groups. Dietary supplementation of GOx has linearly improved the body weight
gain (p = 0.049) and average daily gain (p =
0.040) of suckling piglets. The total tract digestibility of dry matter and
nitrogen was linearly increased with the graded level of GOx supplement. Also, a
linear effect was observed on the glucose and superoxide dismutase of blood
profile with the dietary inclusion of GOx. In summary, our finding indicates
that the dietary inclusion of GOx supplement with corn-wheat-based diet had a
beneficial effect on the nutrient digestibility and blood profile of lactating
sows and improved the growth performance of suckling piglets.
