To produce the desired synchronization of estrus in a group of gilts, treat all of the gilts once daily for the same 14-day period.

• Treat gilts on an individual basis by top dressing MATRIX on a portion of each gilt's daily feed allowance.
  
  
• Administer 6.8 mL (15 mg altrenogest) per gilt once daily for 14 consecutive days.
  
  
• Underfeeding of MATRIX may lead to the occurrence of cystic follicles.
  
  
• Excessive use of a syringe may cause the syringe to stick. This is normal. Simply discard and replace syringe as necessary.
