PRODUCTIVE AND METABOLIC RESPONSE TO TWO LEVELS OF TURNIP (Brassica rapa L.) SUPPLEMENTATION IN GRAZING DAIRY COWS DURING SUMMER

ABSTRACT Forage turnip (Brassica rapa L.) is used as a supplementary feed for grazing cattle in summer. The aim of this study was to evaluate the effect of two levels of forage turnip supplementary feed on milk production, and energy and protein metabolic responses in grazing dairy cattle during sum...
