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...

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...

Abstract — An 8-month-old, virgin Holstein heifer with precocious mammary development was presented for examination. Protein, fat, and lactose in the mammary secretion were 14.90%, 0.12%, and 0.20%, respectively; somatic cell count was 3.9 3 10 6 /mL, with no bacterial infection. The heifer was...

Schmitt, Eric J. -P., Mattos, Ricardo C., Ambrose, Divakar J., Thatcher, William W., Lopes, Flavia L.
The objectives of this observational study were to document ovarian and endocrine responses associated with the treatment of cystic ovarian follicles (COFs) in dairy cows, using gonadotropin releasing hormone (GnRH) and prostaglandin F2α(PGF) with or without exogenous progesterone. A secondary...

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...

Occurrence of retained placenta is preceded by an inflammatory state and alterations of energy metabolism in transition dairy cows
Download2016
Dervishi, Elda, Ametaj, Burim N., Zhang, Guanshi, Dunn, Suzana M., Hailemariam, Dagnachew
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...

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...

Luteolysis, onset of estrus, and ovulation in Holstein heifers given prostaglandin F2alpha concurrent with, or 24 hours prior to, removal of an intravaginal, progesterone-releasing device
Download2004
Ambrose, Divakar J., Hittinger, M. A., Kastelic, John P.
The objective was to determine the effects of giving prostaglandin F2alpha (PGF) concurrent with, or 24 h before, removal of an intravaginal, progesterone-releasing (controlled internal drug release [CIDR]) device, on luteolysis, the synchrony of estrus and ovulation. Eighteen postpubertal...

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...

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...
