Destruction of the architectural and subsequently the functional integrity of the lung following pulmonary viral infections is attributable to both the extent of pathogen replication and to the host-generated inflammation associated with the recruitment of immune responses. The presence of antigenically disparate pulmonary viruses and the emergence of novel viruses assures the recurrence of lung damage with infection and resolution of each primary viral infection. Thus, there is a need to develop safe broad spectrum immunoprophylactic strategies capable of enhancing protective immune responses in the lung but which limits immune-mediated lung damage. The immunoprophylactic strategy described here utilizes a protein ...

Enfermedad Respiratoria En Los Terneros Lecheros, Como Prevenirla, A. D. Garcia, A. R. Daly 2010 South Dakota State University

Enfermedad Respiratoria En Los Terneros Lecheros, Como Prevenirla, A. D. Garcia, A. R. Daly

Dairy Science Publication Database

La enfermedad respiratoria es la segunda causa de muerte (diarrea es la primera) en las terneras lecheras no destetadas. Los problemas respiratorios han aumentado en un 34 por ciento en los últimos 20 años, causando cerca de 21 por ciento de la mortandad de los terneros (NAHMS 2007). Las terneras que sobreviven continúan con un desempeño pobre al convertirse en vacas adultas. Para prevenir este problema, es importante tener en cuenta tanto causas predisponentes como determinantes.


Respiratory Disease In Young Dairy Calves., A. D. Garcia, R. Daly 2010 South Dakota State University

Respiratory Disease In Young Dairy Calves., A. D. Garcia, R. Daly

Dairy Science Publication Database

Respiratory disease is the second leading cause of death losses (scours is the first) in un-weaned heifer calves. Respiratory problems have increased by 34 percent in the last twenty years resulting in nearly 21 percent of all newborn calf losses (NAHMS. 2007). Heifers that survive continue to perform poorly as adult cows. In order to prevent this costly problem it is important to address both determinant and predisposing causes.

Effects Of Wet Corn Gluten Feed And Dietary Particle Size On Ruminal Fermentation And Milk Production, M.L. Sullivan, Barry J. Bradford

Kansas Agricultural Experiment Station Research Reports

Wet corn gluten feed (WCGF) was included in 4 diets at 0, 11, 23, and 34% of diet dry matter. Alfalfa hay was used to maintain at least 10% of particles ≥0.71 inches in length (the top screen of the Penn State Particle Separator) in all diets. Ruminal probes were placed in the rumens of 7 ruminally cannulated lactating Holstein dairy cows to measure ruminal pH. As WCGF increased in the diet, dry matter intake and milk production increased quadratically with 23% WCGF supporting the highest feed intake and milk yield. Ruminal pH and milk fat content were similar ...
