Cattle and sheep handling systems: design points, dimensions and safety checks

Why handling kit is a safety decision first

HSE's information sheet Handling and housing cattle (AIS35) states that every year there are deaths and injuries to farmers and other workers while handling cattle, often caused by poor equipment, ineffective methods of moving cattle and underestimating the strength, speed or behaviour of the animals. The risk rises with cattle that are rarely handled, such as hill or suckler cattle, newly calved cows and bulls.

HSE frames safe handling around three things: the person (fitness, training, calm handling), the equipment (race, crush, loading and bull-handling facilities) and the animal (its temperament and familiarity with handling). A good system reduces reliance on luck and on the fittest person on the farm. HSE also notes that children under 13 should not normally enter cattle housing or handle cattle, and that the risks should be considered carefully before anyone over 65 works with cattle.

Design around how animals move

Temple Grandin's widely used guidance on low-stress handling explains two ideas that should shape any layout. The flight zone is an animal's personal space, larger in wild or stressed animals; the point of balance is usually at the shoulder. Animals move forward when the handler is behind the point of balance and back up when the handler is in front of it. Grandin recommends working at the edge of the flight zone, applying and releasing pressure rather than pushing continuously, filling crowd pens only about half full and keeping noise down.

Layouts that follow from this include curved races that stop animals seeing people or the crush ahead too early, solid sides that block distractions, and entrances that lead animals towards light. HSE's AIS35 makes the same points for cattle, and SRUC's sheep handling note adds that sheep like to follow one another, prefer to move uphill, move towards light and other sheep, move better round slight curves, and dislike shadows, people, noise and smells.

The cattle race and crush: HSE's checklist

AIS35 sets out what a race and crush should provide. Use it as a specification when buying or rebuilding:

• A funnel end on the race and a collecting pen large enough for cattle to feed into it; a circular collecting pen lets staff stand behind a forcing gate safely.
• A race that may curve but has no tight turns, with sides high enough that cattle cannot jump out, fixed to the ground and to each other; sheeted sides reduce distraction.
• A way to hold the lead animal in the race while it waits, with gates operated from the working side so nobody reaches across.
• A crush with a locking front gate and yoke (ideally self-locking), head bars, and a rump rail, chain or bar that is always used.
• The crush secured to the ground or, if mobile, to a vehicle, with space to work around it away from other cattle and good lighting.
• Gates that open smoothly and quietly, and a slip-resistant floor of bolted hardwood, chequer plate or a rubber mat.
• For belly clipping, lower side panels that open fully on both sides without fixed bars that could trap a hand, and an anti-kick bar or apron. For foot trimming, a purpose-designed crush with foot restraints and belly support.

Sheep systems: SRUC's working dimensions

SRUC's technical note on sheep handling facilities (TN606) gives dimensions that make a useful starting point for a new or rebuilt system. The whole facility needs roughly 1.3 m2 per ewe handled in a day. The main components are:

• Gathering pen: 0.65 m2 per ewe or lamb, big enough for a day's handling, with a 3 m entrance gate.
• Forcing funnel: a 30 degree angle of approach, with a 2.4 m closing gate behind.
• Shedding race: at least 3 m from the funnel, ideally 4.5-6 m long. Parallel-sided races are 460 mm wide and about 910 mm high; V-section races are 610 mm at the top and 305 mm at the bottom. Shedding gates 900 mm wide, with solid sides and a textured concrete floor.
• Side pens: at least three, with a combined area equal to the gathering pen and about 0.45 m2 per animal.
• Catching or working pen: circular with revolving gates, about 0.35 m2 per head, radius 1.5-2.6 m and walls 1.1 m high.
• Dosing race: solid sides, a non-return gate at the entrance and a see-through exit gate so sheep keep moving.

Fixed, mobile or both

SRUC notes the move towards lightweight mobile sheep pens that travel round the farm, while a fixed system at the main steading is still needed. The same logic applies to cattle: a fixed race and crush at the main yard, plus a mobile crush and hurdles for outlying grazing. If you buy a mobile crush, HSE's point about securing it applies; it must be anchored to the ground or attached to a vehicle before use.

When comparing systems, ask the supplier: what the maximum animal size is for the crush; which jobs it is designed for (routine treatment, TB testing, clipping, foot trimming, AI); how the yoke and gates are operated and from which side; whether a weigh platform or load bars can be fitted; how the mobile unit is towed and set up, and by how many people; and what spares and servicing are available. For cattle weights and EID readers, see our guide to livestock health sensors.

Keeping the system safe

Handling equipment wears: hinges drop, latches loosen, floors become slippery. Check gates, catches, yokes and floors before each handling day and fix faults straight away. Make sure everyone who handles stock is trained and supervised until competent, and plan any job needing two people before starting. HSE warns never to treat an animal held by gates alone, and to have an escape route when working with animals that cannot be secured. Training options are covered in our farm skills gap guide, and occasional-use kit such as a foot-trimming crush can often be hired or shared; see our machinery sharing guide.
