Summary: | The core intention to undertake this experiment for a period of 21 days is to
evaluate the effect of salicylic acid (SA) supplemented diet on the performance
and blood metabolites of sows and their litters. Sows weighing 208.5 ±
18.34kg and their neonates were used. From day 114 of gestation to 21st day of
lactation(weaning), ten multiparous sows (n = 5/treatment) (Landrace x
Yorkshire) were assigned randomly into one of two treatments: CON (basal diet)
and TRT (CON + 0.05% SA). There was no significant difference in the body
weight, backfat thickness, backfat loss, and body condition score in SA treated
sows compared to sows fed the CON diet. However, the bodyweight of sow was
dramatically reduced by an average of 16kg from farrowing to weaning time. The
dietary inclusion of SA in the sow diet slightly improved the survival rate
(p = 0.065) and showed a higher body weight
(p = 0.009) in piglets. However, there was no significant
difference in red blood cell, Fe, Hematocrit, and Hb concentrations between CON
and TRT sows’ groups, but the total iron-binding capacity (TIBC) was
significantly reduced in sows from the TRT group compared with the CON group
from the beginning to weaning. The outcome of this trial shows that dietary
addition of SA on sows diet from early lactation could increase the birth weight
and TIBC of neonates at the end of the trial. |
