Effect of different concentrations of dietary safflower seed on milk yield and some rumen and blood parameters at the end stage of lactation in dairy cows

In this study, the effects of different concentrations of dietary safflower seeds (SS) were examined for milk production, milk fat and some rumen and blood parameters at the end stage of lactation in dairy cows. Four Holstein cows were assigned to a 4 × 4 Latin Square design with four stages. All stages had 14 d of adaptation and 7 d of data collection periods. The diets were formulated as isoenergetic and isonitrogenous. Cows were fed four concentrate mixtures containing 0% (Control; C), 12.5% (S-I), 25% (S-II), or 37.5% (S-III) crushed SS during the experimental period. Safflower seed intak...
