Final answer:
Udder edema is related to multiple factors including sodium and water retention, not primarily excess dietary calcium. Management focuses on balancing electrolytes.
Step-by-step explanation:
The statement that udder edema is primarily associated with excess dietary levels of calcium in the prepartum diet is False. Udder edema in dairy cows often occurs around the time of calving and is associated with multiple factors, including increased blood flow to the udder, retention of sodium and water, and impaired lymphatic drainage. While dietary management is crucial in the prepartum period, focusing on balancing electrolytes to avoid excessive sodium and ensuring a smooth transition diet to prevent metabolic disorders is more pertinent than solely reducing dietary calcium levels.
