Joest et al. - Incomplete Milking during peak to mid Lactation - Supplemental.pdf

This study evaluated the effects of automated software-based incomplete milking (IM), with milk withdrawal gradually reduced up to 40% over 5.5 days followed by a constant 40% reduction for another 5.5 days, on milk production, udder health, and selected metabolic parameters in multiparous dairy cows during peak to mid-lactation. Using software for controlled automated earlier cluster removal, gradual IM led to short-term reductions in milk yield and high variation in milk fat content whereas udder health and stable somatic cell counts were preserved. Blood analysis revealed shifts in energy metabolism, including decreased serum fatty acids and increased insulin-like growth factor 1 (IGF-1). Milk production after IM increased to pre-IM levels, making IM a viable strategy to reduce lactation-induced metabolic load without compromising udder health or milk yield.
