Preliminary study: from biofortified maize to cow milk enriched in selenium: an on-farm strategy using selenium-enriched silage

Popis výsledku v původním jazyce

Selenium (Se) supplementation is a common practice in dairy nutrition. However, the use of biofortified feedstuffs remains a not fully realized strategy to enhance the Se content of animal derived products. This study explored an on-farm biofortification approach by incorporating Se-enriched maize silage into the total mixed ration (TMR) of dairy cows. Sixty Holstein cows were divided into a control group (CON), receiving a conventional diet with selenite supplementation (0.6 mg/kg Se in TMR), and an experimental group (EXP), in which conventional silage was replaced with high-Se silage (0.9 mg/kg Se in TMR). The trial lasted 22 weeks, including one week of adaptation and four weeks post-supplementation, and assessed Se concentrations in milk, Se transfer efficiency, and key milk components critical for the production of Se-enriched dairy products. The higher Se concentration in the TMR had no adverse effects on milk composition or antioxidant status.
