As with any susceptible livestock species, the key to control of paratuberculosis in beef cattle is to reduce exposure of the susceptible calves to Mycobacterium avium subsp. paratuberculosis (MAP)–contaminated feces. Because beef calves remain with mature, potentially shedding cattle until weaning, control strategies are aimed at providing an environment with the least possible fecal burden and removing MAP shedders as soon as possible. Testing and culling or separation may be more important in beef cattle than in dairy cattle. Seedstock owners have greater potential for economic loss from paratuberculosis, making control program more financially attractive to them than to commercial beef cattle producers.

Multifunctional pH-responsive films were fabricated via layer-by-layer deposition of gelatin, chitosan, and carboxymethyl cellulose (CMC), incorporating selenium nanoparticles (SeNPs) and beetroot extract (BTE), to monitor and preserve beef freshness. SeNPs were synthesized and characterized via various techniques. BTE exhibited promising functional properties, and films demonstrated a significant color transition from red to yellow across pH 2-14.

"Low Carbon Brazilian Beef" (LCBB) represents a Brazilian concept brand that certifies livestock systems adopting specific technical guidelines to minimize methane gas emissions from cattle. Understanding consumers' perceptions of this brand concept can help develop strategies to promote its consumption. The objective of this study was to investigate the perception of Brazilian consumers living in the state of Rio de Janeiro regarding the LCBB through free word association and to evaluate the influence of socio-demographic variables, green consumption values and frequency of beef consumption in associations.
