Stress factors increase the production of adrenaline and cortisol, both of which interfere with the action of oxytocin.
This causes milk let-down to be delayed or even blocked, leading to structurally incomplete milking, more residual milk in the udder, and longer milking times.
These factors can, in turn, lead to a higher incidence of mastitis and poor teat health. Heifers can be extra sensitive due to their limited experience in the milking Parlor or robot!
LOW-STRESS HANDLING BEFORE AND DURING MILKING IS CRUCIAL
Any form of excitement or agitation in the cow during the 30 minutes prior to milking can seriously disrupt milk let-down.
Rough handling can also hinder milk flow, even if the udder has been correctly prepped and/or oxytocin has been administered.
A calm, animal-friendly, and consistent approach (Low Stress Stockmanship), is an efficient, low-cost, and effective strategy that supports milk let-down, udder health, and job satisfaction.
When handling and milking routines align with the cow's natural physiology, not only does performance improve, but also the cow's profitability and longevity. Furthermore, calm handling ensures a safer work environment.
Investing in Low Stress Stockmanship training is therefore a wise and useful investment.
FOCUS ON POSITIVE HUMAN-COW INTERACTIONS
Positive interactions stimulate the production of oxytocin and promote efficient milk production. In contrast, negative interactions block oxytocin release and reduce milk yield.
In summary:
- Cows crave routine: Predictability is essential; they thrive on consistency.
- When cows enter the Parlor or robot calmly and without stress, oxytocin release is higher and more effective. They let down their milk more easily, making the process smoother and more efficient.
- Less stress results in less residual milk, which on some farms leads to a decrease in mastitis cases.
- Calm handling benefits both humans and animals, creating a win-win situation regarding welfare, performance, longevity, safety, and job satisfaction.
