The objectives of this study were to evaluate metabolic and innate immunity alterations in the blood of transition dairy cows before, during, and after diagnosis of lameness during periparturient period. Blood samples were collected from the coccygeal vain once per week before morning feeding...
Characterisation of bacterial microbiota of the vagina of dairy cows and isolation of pediocin-producing Pediococcus acidilacticiDownload
Background Uterine infections in dairy cows lower profitability of dairy operations. Infections of the reproductive tract are related to the overgrowth of pathogenic bacteria during the first three weeks after parturition. However, alterations in the vaginal microbiota composition in the first...
Effects of prepartal oronasal administration of lipopolysaccharide on milk composition and productivity of transition Holstein cowsDownload
The aim of this study was to evaluate the effects of repeated oronasal administration of lipopolysaccharide (LPS) on milk composition and the overall productive performance of dairy cows. One hundred pregnant Holstein dairy cows were randomly assigned to two treatment groups (n = 50). 30 cows out...
Innate immunity and carbohydrate metabolism alterations precede occurrence of subclinical mastitis in transition dairy cowsDownload
Background This study examined whether activation of innate immunity and alterations of carbohydrate and lipid metabolism precede development of subclinical mastitis (SCM). Methods Blood samples were collected from the coccygeal vein from 100 Holstein dairy cows at -8, -4, disease diagnosis week,...
Intraruminal administration of Megasphaera elsdenii modulated rumen fermentation profile in mid-lactation dairy cowsDownload
This study evaluated the effects of intraruminal administration of Megasphaera elsdenii on ruminal fermentation patterns, the profile of plasma metabolites, and milk yield and composition of mid-lactation dairy cows. Eight primiparous, ruminally cannulated Holstein cows were arranged in a paired...
Intravaginal lactic acid bacteria modulated local and systemic immune responses and lowered the incidence of uterine infections in periparturient dairy cowsDownload
The objective of this investigation was to evaluate whether intravaginal infusion of a lactic acid bacteria (LAB) cocktail around parturition could influence the immune response, incidence rate of uterine infections, and the overall health status of periparturient dairy cows. One hundred pregnant...
Maintaining a healthy rumen ecosystem is crucial to avoid systemic disorders in cattle, but also critical to ensure that milk and meat are produced from healthy animals in an efficient and cost-effective manner. In fact, today’s intensive management systems of cattle typically encourage the...
In this review article we present an overall summary of the role that high-grain/low forage diets have on rumen composition of microbiota and how changes in the diet affect the release of bacterial cell wall components that are toxic to the host. One of these toxic compounds is lipopolysaccharide...
Occurrence of retained placenta is preceded by an inflammatory state and alterations of energy metabolism in transition dairy cowsDownload
Background Failure to expel fetal membranes within 24 h of calving is a pathological condition defined as retained placenta (RP). The objective of this investigation was to evaluate whether there are alterations in several selected serum variables related to innate immunity and carbohydrate and...
Oronasal administration of lipopolysaccharide prepartum modulated plasma metabolite patterns in periparturient dairy cowsDownload
The objective of this study was to evaluate whether repeated oronasal administration of LPS before parturition showed effects on metabolic and clinical responses in periparturient dairy cows. Hundred Holstein dairy cows were randomly allocated to two treatment groups (n = 50). Thirty cows out of...
