An experimental study is being conducted to evaluate the performance of cows fed sorghum roughage, a new feed crop in the Netherlands, replacing maize. The trial involves grouping cows into three sets, each receiving different rations, with a control group receiving no sorghum. The study will assess various factors including feed intake, milk yield, milk composition, body weight, and methane emissions. The results, expected in autumn 2021, are anticipated to provide insights into the benefits and suitability of sorghum as roughage for lactating cows, potentially supporting the rotation of crops and addressing the challenges of continuous maize cultivation.
