Opuntia ficus-indica as a supplement for gilts in late gestation and lactation: effects on biochemical parameters and voluntary feed intake

This study evaluated the effect of Opuntia ficus-indica L. supplementation on gilts during late gestation and lactation, particularly on their biochemical parameters and voluntary feed intake (VFI) at lactation. Thirty-two gilts were randomly distributed into two groups: control group (CG), gilts fed conventionally and experimental group (EG), gilts fed commercial feed plus O. ficus-indica. Glucose concentration was lower (P < 0.05) in the EG. Insulin concentration was higher in the gilts that consumed O. Ficus-indica. Triglyceride's concentration was lower (P < 0.05) at gestation, farrowing and lactation in the EG. Total cholesterol was higher (P < 0.05) in gestation and lactation in the CG. HDL present higher concentration in lactation in the gilts that consumed O. Ficus-indica. LDL concentration was higher (P < 0.05) in gestation and lactation in the CG. Leptin concentration was higher (P < 0.05) at lactation in the CG. The gilts of the EG had higher VFI (22.6% more) and presented less body weight loss (3.7% less) at weaning (P < 0.05). These findings suggest that O. Ficus-indica favourably regulates the biochemical indicators involved in the development of insulin resistance, and this is reflected in the higher VFI and lesser body weight loss at weaning.

Automated summary

This study found that Opuntia ficus-indica extract favorably regulates biochemical indicators related to insulin resistance development, leading to higher VFI and less body weight loss in lactating sows.
