SPECIAL STORY 68 FEED & ADDITIVE MAGAZINE November 2023 Alternatively, VistaPre-T can be applied on the top of the ration to enable extra energy supply and improved performance. In another study, 350 milking cows maintained as one group were fed a maize and grass silage-based ration, with VistaPre-T applied on the top of the ration. The average milk yield (kg/cow/day) in the pre-trial period and after feeding VistaPre-T was recorded and indicated increased milk yield in every stage of lactation. Average milk yield increase with VistaPre-T per lactation stage. Transition: 0-50 days in milk (DIM), early: 51-100 DIM, Mid: 101-200, Late: 201-400. CONCLUSION As the commitment to net zero by 2050 grows ever stronger, so does the spotlight and pressure on producers to reduce livestock emissions. Improving overall efficiency – specifically, efficiency fibre utilisations – helps honour this commitment, while acting as a means to support the sustainability of livestock production. An effective pre-treatment like VistaPre-T helps extract more energy from feed and forage – critical to not only maximising feed efficiency, but also helping producers reduce costs and improve farm profitability; in the long-term, ensuring the sustainability of livestock production.
