• Describe essential components of handling facilities for livestock.
• Explain the principles of low-stress animal handling.
• Identify common causes of stress in livestock.
• Apply knowledge of animal behaviour to improve handling.

Lesson summary

Animal welfare is paramount in ethical and sustainable agricultural practices. In South Africa, where livestock farming contributes significantly to the economy and food security, understanding and implementing appropriate handling facilities and welfare practices is crucial for both the well-being of the animals and the success of farming enterprises. Poor handling and inadequate facilities can lead to stress, injury, reduced productivity, and ultimately, economic losses.

Furthermore, consumers are increasingly aware of animal welfare standards, and farmers who prioritize these standards gain a competitive advantage.

Lesson notes

2.1 Animal Welfare: Definition and the Five Freedoms Animal welfare refers to the physical and psychological well-being of animals. It is not simply about preventing cruelty; it encompasses providing animals with a good quality of life. A widely accepted framework for assessing animal welfare is the "Five Freedoms," developed by the Farm Animal Welfare Council (FAWC): Freedom from hunger and thirst: This means providing readily accessible fresh water and a diet to maintain full health and vigour.

Freedom from discomfort: This involves providing a suitable environment, including shelter and a comfortable resting area. Consider protection from weather extremes like scorching sun or freezing rain. Freedom from pain, injury, or disease: This requires prevention, rapid diagnosis, and treatment of any health problems. Regular veterinary check-ups, vaccinations, and parasite control are vital.

Freedom to express normal behaviour: This means providing sufficient space, proper facilities, and company of the animal's own kind. This includes allowing animals to engage in natural behaviours like grazing, socialising, and nesting.

Freedom from fear and distress: This entails ensuring conditions and treatment that avoid mental suffering. Low-stress handling techniques, proper training, and a predictable routine can help minimise fear and distress. 2.2 Essential Components of Handling Facilities Well-designed handling facilities are essential for safe, efficient, and low-stress livestock management. These facilities vary depending on the species of animal, but generally include the following components: Holding Pens: These are areas where animals are gathered before being moved into the handling system. They should be spacious enough to prevent overcrowding and allow animals to move freely. The flooring should be non-slip to reduce the risk of injuries. Proper drainage is also key to prevent disease.

Race (or Drafting Race): A race is a narrow passageway that funnels animals towards the crush or loading ramp. Races should be solid-sided to prevent animals from seeing distractions and becoming agitated. The width of the race should be adjustable to accommodate different sizes of animals, preventing them from turning around. A curved race can be more effective than a straight race, as animals tend to move more easily around curves.

Crush (or Squeeze Chute): A crush is a sturdy, confined space where individual animals can be safely restrained for procedures such as vaccinations, tagging, or artificial insemination. Crushes are typically equipped with head bails and side bars to immobilise the animal. Look for crushes that are adjustable to fit different animal sizes and have easy-to-operate locking mechanisms.

Loading Ramp: A loading ramp allows animals to be safely loaded onto trucks for transport. The ramp should have a gentle slope, non-slip flooring, and side rails to prevent animals from falling. Ideally, the ramp should lead directly onto the truck bed without any gaps. Consider adjustable ramps to accommodate different truck heights.

Head Bail: A specific restraining device within the crush that secures the animal's head, enabling safe administration of injections or other treatments. Different head bail designs exist, some more humane than others.

Drafting Gates: Gates used to separate animals into different groups after they have been processed through the crush. This allows for efficient sorting and management of livestock.

Example: Design considerations for sheep handling facilities differ from those for cattle. Sheep are more easily stressed and prone to injury.

Therefore, sheep handling facilities should have smooth, rounded edges to prevent bruising, and races should be narrower to prevent sheep from turning around. Cattle handling facilities, on the other hand, require stronger construction to withstand the greater size and strength of the animals. 2.3 Principles of Low-Stress Animal Handling Low-stress animal handling techniques are based on understanding animal behaviour and minimising stress during handling procedures.

Key principles include: Understanding Flight Zones: Every animal has a "flight zone," which is the area surrounding it that, when encroached upon, will cause the animal to move away. The size of the flight zone varies depending on the species, breed, temperament, and previous experiences of the animal. Understanding flight zones is crucial for moving animals efficiently and calmly. Approach the animal at the edge of its flight zone to encourage it to move in the desired direction.

Using the Point of Balance: The "point of balance" is typically located at the animal's shoulder. When the handler stands in front of the point of balance, the animal will tend to move backwards. When the handler stands behind the point of balance, the animal will tend to move forwards.

Moving Animals in Small Groups: Moving animals in smaller groups reduces stress and allows for better control.
