Losses in milk production and quality due to milk somatic cell count and heat stress of Holsteins cows in temperate climate

Abstract: The aims of present study were to evaluate the effects of milk somatic cell count (SCC) and heat stress on yield and milk composition of cows in a herd for commercial production in a temperate region during the period [2008][2009][2010][2011][2012]. Data from the monthly milk test-day records of 161±9 Holstein, totaling 9,650 milkings, were provided by the Association of Holstein Cattle Breeders of Parana State, and analyzed by descriptive analysis, correlation, analysis of variance, and regression analysis.

“…Such stress can compromise the animal's immune response, leading to a heightened risk of mastitis, which consequently raises the somatic cell count (SCC). Elevated temperatures combined with high humidity levels provide an ideal environment for the rapid proliferation of microorganisms, thereby enhancing vulnerability to infections (Ludovico et al, 2015).…”

“…Desta forma, a avaliação internacional da qualidade do leite é realizada pela contagem de células somáticas (CCS), contagem bacteriana total (CBT) e contaminantes (Santos & Fonseca, 2019), sendo que, os mesmos em desacordo com a Instrução Normativa vigente prejudicam o rendimento industrial dos produtos lácteos, tempo de prateleira, segurança alimentar dos produtos (Lampugnani et al, 2018), além da saúde da glândula mamária (Neves et al, 2019).
