The transition period,(three weeks before and after parturition), is seriously valuable for health, productive performance and success of dairy animals (Drackley 1999). The dairy animal faces massive metabolic and endocrine adjustments during the late gestation and transition period (Drackley et al., 2001, DeFrain et al., 2005). Thediminution in dry matter intake around parturition time and a large demand in nutrients that the cows need for milk production are the most serious physiological changes taking place throughout this period (Drackley 1999, Ingvartsen and Andersen 2000). Moreover, during late gestation period, the growing uterus occupies a tremendous size of the abdominal cavity resulting in a physical compression of the rumen, which causes reduction in the rumen volume, then after calving; the uterus comes back toward the pelvic inlet (Ingvartsen and Andersen 2000). Dry matter intake of dairy cows around parturition time is reduced due to the diminution in rumen volume by the growth of fetus and other hormonal changes reduce dry matter intake (Ingvartsen and Andersen 2000). Pregnancy, calving and lactation create a physical and metabolic stress on the dairy animal that, contributes to a reduction of cows resistance (Melendez 2006). As well as, there are affections like milk fever, subclinical hypocalcaemia, ketosis, fatty liver syndrome, retained placenta, metritis, mastitis and abomasum displacement primarily affect dairy cows during the transition period (Drackley 1999, Melendez 2006).
