Abstract

This study evaluated the effects of a commercial SYMBIOTIC product containing a probiotic(E. faecium), a prebiotic (Fructooligosaccharide)and a phytogenic compound (sea algaeextract)on performance and health of Holstein diary calves. 29 newborn calves were assigned by sex andbirth date to 10 blocks and allocated to 3 treatments; control (CON, n = 9); CON supplemented withsymbiotic via milk (5 g /calf /d) from d 3 of age (SYN3; n = 10); and CON supplemented withsymbiotic via milk from d 30 of age (SYN30; n = 10). Calves were abruptly weaned based on theconsumption of a minimum of 680 g/d of starter feed for 3 consecutive d and immediately moved togroup pens, where they received the respective additives via starter feed until d 75. Body weight(BW) and body growth measures were recorded biweekly during preweaningand weekly duringpostweaningperiod.Feces were scored weekly and sampled on d 14, 42 and 70. Blood sampleswere taken on weaning day, 24 h postweaningand d 75. During the first 2 wk of the experiment,BW decreased in the CON and SYN30 groups (890and 240g, respectively), while it wasincreased numerically in SYN3 group (+500 g). Mean BW was higher in SYN30 than SYN3 andCON groups (62.9 vs. 59.9, and 59.2 kg, respectively, P < 0.05). However, treatments did not affectfinal weight, ADG, preweaningstarter intake, and weaning age. Also, there were no significantdifferences between treatments in fecal microbial count and blood parameters. Overall, except for ahigher mean BW in SYN30 treatment, simultaneous supply of preandprobioticsand phytogenicsas well as time of supplementation did not affect performance and health-related parameters in dairycalves.
