Prevalence of individual and bulk tank milk antibodies of bovine herpesvirus type 1 and its relation to milk quality parameters on dairy farms in Catalonia (north‐east Spain) [PDF]

Veterinary Record Open, Volume 4, Issue 1, April 2017., 2017
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 ...

Biosynthesis of Silver Nanoparticles by Polysaccharide of Leucaena leucocephala Seeds and Their Anticancer, Antifungal Properties and as Preservative of Composite Milk Sample

Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022
The AgNPs were synthesized using water‐soluble polysaccharides extracted from the Leucaena leucocephala seeds. The UV‐visible spectrum of the AgNPs showed a sharp absorption peak at 448 nm. The XRD analysis showed four major peaks of the crystalline AgNPs with planes of a face‐centered cubic lattice of silver.
