Jenquip Pasture Cages are robust, zinc-plated and stackable for easy transport, and will provide many years of trouble-free pasture monitoring.

Pasture Cages are used to help calculate pasture growth rates by excluding stock from grazing a specific area. The pasture within the cage can be measured either directly, such as by cutting, drying and weighing, or indirectly using measurement devices.

Each Jenquip Pasture Cage covers an area equal to 0.2m.sq, and is supplied with pegs to hold the cage down so that even cattle rubbing won’t dislodge them.

A typical set-up to monitor grass growth in a paddock would use 4-10 Pasture Cages.

  • Low-cost — probably the cheapest way to monitor grass growth!

  • Robust — built to withstand the rigours of sharing a paddock with grazing livestock.

  • Stackable — makes for easy transport and storage.

  • Pegs included — to prevent even rubbing cattle dislodging the Pasture Cage.

  • Zinc-plated — for a long service life.

  • Standard size — each Pasture Cage covers an area approximately 0.2 metres square.

  • Re-usable — simple to move from paddock-to-paddock, or leave permanently in one place.

Position the Pasture Cages so that they are spread evenly across the paddock, or are targeted at any specific areas where you want to monitor pasture growth.

Avoid placing the Pasture Cages over obvious areas where urine or dung are present, or where grass growth is boosted by urine or dung from earlier livestock grazing the paddock.

Cut the area where the Pasture Cages are to be placed and discard the grass, then use the supplied pegs to secure each firmly to the ground.

Pasture is harvested from cages after a number of days or weeks and weighed. Samples are then taken and weighed-dried-reweighed to calculate the dry matter content of the grass as a percentage (%).

Sample dry matter is calculated using the following equation:

  • (Weight of dried sample (g) / Weight of fresh sample (g)) x 100 = Sample dry matter (%)

These next equations are then used to calculate the daily pasture growth rate:

  • No. Jenquip Pasture Cages x 0.2m.sq = Total area (m.sq)

  • (Fresh weight of grass collected (g) x Dry matter (%) x 10) / Total area (m.sq) = Pasture dry matter (kg DM/ha)

  • Pasture dry matter (kg DM/ha) / No. days growth = Pasture growth rate (kg DM/ha)
