One experiment was conducted to evaluate the influence of glycerin (GLY) on animal performance and health when used as a partial replacement for roughage in receiving diets. The second experiment was conducted using ruminally and duodenally cannulated steers in a 4 × 4 Latin square to determine the site of nutrient digestion and ruminal fermentation characteristics when GLY replaced roughage at...

BACKGROUND Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) is a significant disease among domestic and wild cattle. The BHV-1 infection was first detected in Finland in 1970; presumably it was imported in 1968. The infection reappeared in the large-scale bulk-tank milk surveillances which started in 1990, and was eradicated in 1994. Our aim is to describe the epid...

Sera from 221 cattle were collected in 25 farms in Morocco to investigate the evidence and circulation of some of the main bovine abortive agents in the dairy cattle farming, where abortions are often reported. All sera were examined for brucellosis, 176 for neosporosis, 88 for leptospirosis, and 42 for Bovine viral diarrhoea (BVD/MD), Bovine Herpesvirus 1 (BHV-1) (Infectious bovine rhinotrache...

Bovine herpesvirus type 1 (BoHV-1) is the causative agent for infectious bovine rhinotracheitis and infectious pustular vulvovaginitis in cows or balanoposthitis in bulls. In this study, individual and bulk tank milk (BTM) samples from 5 Catalan dairy farms with different control strategies against BoHV-1 were analysed during the course of a year for milk quality parameters and glycoprotein E (...

The aim of the present work was to evaluate the prevalence and efficacy of IBR control measures in selected cattle herds in Lithuania. Serological investigations in 1997 2007 years (34600 blood sera samples tested) showed that BHV-1 infection mostly detected in cows (33.86%), less in heifers (8.77%) and in bulls group (1.69%). In majority of the cases seropositive bulls were detected in quarant...

Endemic infectious diseases (such as mastitis, infectious bovine rhinotracheitis (IBR), Johne’s disease (JD), or tuberculosis in cattle) are common causes of disease in livestock. They affect health and well-being and reduce the economic potential of each animal, herd and industry. Endemic diseases exhibit necessarily complex epidemiologic and pathogenic behavior; those that exhibit less comple...
