Step 1
(i) a raddling harness
Answer
A raddling harness is an essential tool in sheep production that serves multiple purposes. It detects mating behavior in rams and predicts lambing dates. This allows the farmer to monitor which ewes have joined with the ram.
The raddling harness is designed to apply a colored marking on the ewes when the ram mounts them, making it easier to identify those that have been bred. If multiple colors are used (usually 2 to 3 for clarity), it enables the identification of infertile rams or ewes that need further attention. Additionally, the colors should be changed every 17 days for a new breeding cycle to provide accurate data on breeding status.
Step 2
(ii) footrot
Answer
Footrot is a bacterial disease that can lead to significant issues in sheep production. It is contagious and characterized by symptoms such as pain and lameness in the affected sheep. This can result in reduced feed intake, which contributes to a loss of condition.
The impact of footrot on sheep fertility is notable, as it can lower reproductive performance, particularly in rams. Treatment often includes administering copper sulfate or formalin, hoof paring, and maintaining proper hygiene to prevent clostridial species from thriving in wet soil or dirty housing. Regular vaccination and the use of antibiotics may be necessary to control outbreaks, and severe cases can lead to culling of infected sheep.
