How an Effective Drench Boosts Conception Rates 🐮
The link between worm control and fertility is direct and economically significant. It all comes down to Body Condition Score (BCS).
The Problem: A high worm burden, even a sub-clinical one (where animals don't look sick), damages the gut lining. This impairs the animal's ability to absorb nutrients from its feed.
The Cascade Effect:
Poor nutrient absorption leads to weight loss or poor weight gain.
The animal's Body Condition Score (BCS) drops.
A cow or heifer with a low BCS at joining will divert all energy to survival, not reproduction. This leads to anoestrus (not cycling).
The Solution: An effective pre-joining drench removes the parasite burden. The gut can heal, nutrient absorption improves, and the animal can efficiently convert feed into energy for both maintaining body condition and cycling.
Bottom Line: A strategically timed, effective drench helps ensure females reach their target BCS for joining, leading to higher conception rates, a tighter calving window, and more profit.
