Change in body temperature can be an early indicator of illness. In calves, body temperature is routinely estimated from rectal temperature measurement. Integrating oral temperature sensors into automated feeding systems might present a fea...
Milk component, farm, and industry-level factors associated with elevated free fatty acids in bulk tank milk on conventional dairy farms [0.03%]
常规奶牛场牛奶中游离脂肪酸升高的乳品组分、农场和工业层面的相关因素分析
Hannah M Woodhouse,Stephen J LeBlanc,Trevor J DeVries et al.
Hannah M Woodhouse et al.
Elevated concentrations of free fatty acids (FFA) in bulk tank milk indicate excessive milk fat breakdown. Levels exceeding the sensory threshold of ≥1.20 mmol FFA/100 g of milk fat compromise milk quality. Average FFA levels on Ontario (O...
