Incidence of Hypovitaminosis E in Calves and Therapeutic Remedy by Selenium-Vitamin Supplementation

Abstract: The objective of the research project was to assess incidence of hypovitaminosis E in calves of dairy cows during milk nutrition from different farms in the Czech Republic and to verify the effect of hypovitaminosis E therapy consisting in oral and parenteral administration of a seleniumvitamin supplement.Vitamin E concentration in blood serum of 350 calves from 39 different dairy farms was determined. The average vitamin E concentration being 3.55 ± 2.24 µmol·l -1 , hypovitaminosis (defined as vitamin E conce… Show more

“…Kalber et al (2011) found 3-7 mg of α-tocophero per kg DM in various plants. In contrast, Pavlata et al (2008) reported 80-200 mg of α-tocopherol per kg DM in fresh forage. The almost doubled concentration of vitamin E in breast muscle after 19 days of pasture indicates that there is a good bioavailability of vitamin E in the pasture.…”

“…Additionally, no relation between the concentration of vitamin e in serum of the dam and its concentration in colostrum was determined (Pavlata et al 2004c). A very high incidence of hypovitaminosis e (77.7%) in calves of dairy cows during milk nutrition was identified in previous study, too (Pavlata et al 2005b). It may thus be said that the quality of colostral nutrition was insufficient in most of the herds.…”

“…According to Butler and Smith (1989), the extent and duration of the NEB is negatively associated with the reproductional abilities of dairy cows. The energy status in dairy cows is evaluated by energy intake and output (Rukkwamsuk et al, 1999) and expressed by body condition score (Pavlata et al, 2008). When the losses of body condition are 1 point or more, a signifi cant decrease of fertility demonstrated by a lower conception rate is detected (Říha et al, 2000).…”
