Additional important Information to know while administering MATRIX™ to gilts.2

 

A small percentage of gilts (less than 5%) will exhibit estrus during the 14-day treatment period.

 

To reach breeding goals, a program of PG 600 and MATRIX™ may be used. If replacement gilts are not cycling, PG 600 will induce fertile estrus in healthy, prepuberal gilts, over 5 1⁄2 months of age and weighing at least 187 lb.; or in healthy, weaned sows experiencing a delayed return to estrus. If gilts are not mated during their first estrus, then MATRIX™ can be used.
