Evaluating the effectiveness of Vinasse in increasing milk production in dairy cows
Optimising the diet
Dairy farming aims to increase productivity while maintaining high milk quality. One effective approach is to use modern feed additives that help balance energy, protein and other nutrients. Protein feed ingredients, including liquid supplements, can improve feeding efficiency and help cows express their genetic potential.
Advances in manufacturing have increased the availability of food-industry by-products. Using these materials in compound feed can lower diet costs, improve the profitability of milk production and create opportunities for innovative protein supplements. Vinasse is one such feed ingredient: it is derived from sugar processing and yeast production and contains protein and other valuable nutrients.

Introducing Vinasse into the diet
Adding Vinasse at 1.0 kg per head helps compound-feed particles adhere more firmly to other ingredients, such as hay and silage. This makes the ration more uniform and reduces feed sorting. Its liquid form helps distribute nutrients evenly and improves palatability, encouraging animals to consume more of the total mixed ration.
Increased milk production
A trial was conducted to evaluate the effect of Vinasse on milk production. Forty-five lactating cows were allocated to three matched groups. The control group received the standard compound feed, while the treatment groups received compound feed supplemented with 0.5 kg or 1.0 kg of Vinasse.
Including Vinasse throughout lactation produced a noticeable improvement in milk production. In the group receiving 1.0 kg per head, daily and total yields of milk standardised to 4% fat increased by 7%, and total milk fat yield also increased by 7%. The trial showed that this protein ingredient provides an additional available protein source for the growth and development of rumen microorganisms, improving digestion and nutrient utilisation.
Blood biochemistry showed that triglyceride and ALT levels remained within the normal range, supporting the positive effect of the ingredient on metabolic function and liver health.

Commercial impact and benefits
Vinasse offers benefits beyond higher milk yield. It improves feed quality, reduces ration sorting and increases protein utilisation. As demonstrated in the trial, it works alongside other feed ingredients to provide balanced nutrition, improve metabolic processes and support more consistent milk production.
