Effects of dietary inclusion of Opuntia ficus-indica on the glycemia and productive performance in lactating sows

  • 2019
  • Issue: 5
  • Volume: 49
G. Ordaz, A. Juárez, K. Vargas, R.E. Pérez & R. Ortiz Page: 824 - 834

Sows with increased blood glucose during late gestation may have decreased feed intake in lactation. Supplying dietary fibre to the sow reportedly modulates blood glucose and improves feed intake. The objective of this study was to evaluate the effects of…
