Comparison of Different Management Techniques on Hay Wastage in Horses Fed Alfalfa Hay

Abstract

Two studies were conducted to determine waste of alfalfa hay when fed to horses.  In study one, four quarter/paint horse open mares (Equus caballus) between the ages of four and seven years old were used to determine hay wastage on round baled alfalfa (Medicago sativa) (ALF) hay when hay rings were present or absent.  Average daily gain (ADG), dry matter intake (DMI), and DMI as a percentage of body weight were also collected.  Results indicated that percent wastage was higher (P<0.001), for horses fed hay without rings (WOR) than those fed hay with hay rings (WR).  No differences (P>0.05) were found in ADG.  Furthermore, there were no differences (P>0 .05) in dry matter intake or DMI as a percent of body weight in horses between treatments.  In study two, fifteen long yearling quarter horses were used to determine square bale waste in a stall setting while feeding in a feeder versus on the ground. DMI and ADG were also collected.  Results indicated that percent wastage was higher (P<0.05), for horses fed hay on the ground versus in the feeder.  No differences (P>0.05) were found in DMI or ADG.
