Alterations of innate immunity reactants in transition dairy cows before clinical signs of lameness
Download2015
Dervishi, Elda, Hailemariam, Dagnachew, Zhang, Guanshi, Goldansaz, Seyed A., Deng, Qilan, Dunn, Suzanna M., Ametaj, Burim N.
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 acidilactici
Download2013
Wang, Yvonne, Ambrose, Divakar J., Ametaj, Burim N., Gänzle, Michael G.
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...

Fecal and urinary lignans, intrafollicular estradiol, and endometrial receptors in lactating dairy cows fed diets supplemented with hydrogenated animal fat, flax or sunflower seed
Download2008
Colazo, M. G., Okine, E. K. , Ambrose, D. J., Dyck, M. K., Oba, M., Thangavelu, G.
We hypothesized that the inclusion of flaxseed in the diets of lactating dairy cows will increase urinary and fecal concentrations of the lignans, secoisolariciresinol diglycoside (SDG), enterolactone and enterodiol, reduce intrafollicular concentrations of IGF-I and estradiol, and subsequently...

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...
