The experiments studied the influence of the vegetation phase of eastern galega (Galega orientalis Lam.) plants in the conditions of the North-Western region of Russia on the characteristics of the nutritional properties of the feed prepared from it. It was established that eastern galega should be harvested in the North-Western region for grass flour and pellets in the stalk phase. For the preparation of other types of feed (hay, haylage, silage) it should be harvested in the budding phase - the beginning of flowering, which will allow to get high-quality and nutritious feed for livestock.
