Description
Yaqiong Ren and colleagues compared protein sources in diets for cows around calving in a 2026 feeding study. Protein supply shapes rumen microbes, metabolism, and immune balance during the stressful weeks before and after birth. The team asked whether plant meals other than soybean change that picture.
Sixty cows were split into four groups fed equal energy and nitrogen diets based on soybean meal, rapeseed meal, linseed cake, or sunflower cake. Rumen fluid, blood, digestion, and waste metabolites were tracked across calving. The linseed and sunflower groups gained more helpful rumen bacteria, including fiber digesters. Blood and hormone patterns also differed by diet, with linseed giving the strongest immune response signs. The authors map how protein source steers the whole system.
