Scientific & Biological Overview
To weigh sheep accurately without a livestock scale, pull a soft measuring tape snugly through the wool right behind the front legs. Knowing their real weight ensures accurate dewormer dosing and feed planning.
Frequently Asked Questions
How do you measure a sheep’s heart girth through thick wool?
Part the fleece with your fingers and pull the measuring tape firmly until it sits snug against the skin directly behind the front legs.
How long is a sheep pregnant?
Ewes have an average gestation period of 147 days (roughly 5 months), ranging between 144 and 152 days.
Why is accurate sheep weight so critical for deworming?
Under-dosing sheep with dewormers is the primary cause of parasite resistance. Accurate weight ensures you give the full clinical dose needed to clear internal parasites.
