The effect of seasonal undernutrition on the protein fractions in the blood of Moroccan cattle

: In a trial including 84 cattle from three farms near Rabat (Morocco) the influence of undernutrition (dry season September to February) on the concentration of total protein and its fractions in the blood of cattle was investigated. The results out of the field were confirmed by comparing these concentrations during an experimental cycle of sufficient--insufficient--sufficient feed. It was obvious that malnutrition decreases the concentration of total protein and some of its fractions (albumins, gamma-globulins) in the blood by about 10%, while alpha- and beta-globulins remained nearly uneffected.
