Hormones affects on Animal Behaviour

Three Hormones that will affect livestock behaviour changes:

  1. Testosterone

    • Behavioral Effect: Primarily associated with aggression, territoriality, and increased activity in male livestock (e.g., bulls, boars).

    • Context: Higher levels in uncastrated males can lead to increased fighting or riding behaviors, and this hormone is often managed to reduce aggression in production settings.

  2. Estrogen (Estradiol)

    • Behavioral Effect: Triggers estrus (heat) behaviors in female livestock (cows, sows), leading to increased vocalization, restlessness, and social interactions.

    • Context: Estrogens are naturally occurring hormones that play a key role in maternal behavior and in identifying the proper time for breeding.

  3. Oxytocin

    • Behavioral Effect: Promotes maternal bonding between the mother and newborn, and is crucial for calming behavior during milk ejection.

    • Context: Beyond lactation, oxytocin encourages calm, social behavior and reduces fear, which is essential for interaction between mothers and young

We can manage these with differenct approaches- casturations, drugs, etc
