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...

Effects of prepartal oronasal administration of lipopolysaccharide on milk composition and productivity of transition Holstein cows
Download2013
Ametaj, Burim N., Dunn, Suzanna M., Zebeli, Qendrim, Iqbal, Summera, Mansmann, Dominik A.
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...

Intraruminal administration of Megasphaera elsdenii modulated rumen fermentation profile in mid-lactation dairy cows
Download2012
Mazzolari, Alberto, Yang, Wen Z., Terrill, Sarah J., Zebeli, Qendrim, Dunn, Suzanna M., Ametaj, Burim N.
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 cows
Download2015
Dunn, Suzanna M., Odhiambo, John F., Farooq, Umar, Ametaj, Burim N., Lam, Tran, Deng, Qilan
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...

Novel Mucosal Vaccines to Improve Immune and Health Status of Periparturient Dairy Cows and Increase their Productive Potentials
DownloadFall 2013
The transition period is critical for the health and productivity of dairy cows. Feeding high-grain diets immediately after parturition is necessary to support high milk production. However, high-grain diets are associated with acidic rumen pH and alterations in the composition of rumen...

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...

Oronasal administration of lipopolysaccharide prepartum modulated plasma metabolite patterns in periparturient dairy cows
Download2013
Dunn, Suzanna M., Iqbal, Summera, Zebeli, Qendrim, Mansmann, Dominik A., Ametaj, Burim N.
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...

Profiles of energy metabolites and haptoglobin in dairy cows under organic management in Alberta farms
Download2013
Odhiambo, John F., Dunn, Suzanna M., Farooq, Umar, Ametaj, Burim N.
Profiles of energy metabolites and haptoglobin (Hp) in dairy cows that are transitioned from conventional to organic management in various Alberta farms were compared with those of dairy cows managed conventionally at the University of Alberta dairy farm. Blood samples were collected during the...

Repeated oronasal exposure to lipopolysaccharide induced mucosal IgA responses in periparturient dairy cows
Download2014
Dunn, Suzanna M., Iqbal, Summera, Zebeli, Qendrim, Mansmann, Dominik A., Ametaj, Burim N.
This study investigated the effects of repeated oronasal treatment with lipopolysaccharide (LPS) on the humoral immune responses in saliva, vaginal mucus, and the plasma markers of the acute phase response in periparturient dairy cows. One hundred pregnant Holstein cows were administered either 3...
