Separate-sex feeding considers the differences in head size and height between males and females and allows for more effective control of body-weight gain and uniformity in each sex.

Using separate-sex feeding equipment will:

• Provide the proper feeder space and feed volume for both sexes
• Reduce overconsumption by preventing male access to female feed and vice versa
• Help manage body-weight gain and reproductive performance.
• Prevent male access to female feed by fitting:
  • Grills (grid or toast rack)
  • Plastic pipe in the apex of the grill further restricts male access
  • Roller bar

• Delay male feeding until about 5 minutes after the female feeders have been filled
• Monitor feeding behaviour daily until males are excluded from female feeders
• Male feeder height 50-60 cm (20-24 in) above the litter
• Reduce male feeders as male numbers decline
• If body-weight gain is too high and/or uniformity is poor
• Check for damage, displacement or irregularity of gaps of the grills
• Check feeding space
• Check feed distribution and feed cleanup times.
