Abstract / Zusammenfassung

Effect of feed additives based on lauric acid (LA) on performance and faecal score in piglets. A total of 192 piglets were distributed in 24 pens from 25 to 66d of age (42d feeding period). The study was divided into two feeding phases; starter (25 to 38d) and grower period (39 to 66d). Treatments were: CON-, diet without additives nor antibiotics; CON+, diet with Doxycycline (0.25g/kg and 0.13g/kg in starter and grower diets); DIC, CON- diet plus sodium salt of coconut fatty acids distillate (DICOSAN) at 3kg/t and 1kg/tn in starter and grower diets; MON, CON- diet plus monolaurine at 2.1kg/t and 0.7kg/tn in starter and grower diets. The dosage of both products was made at same level of LA (0.96kg LA/t starter and 0.32kg LA/t grower). All parameters were analyzed using a one-way ANOVA via SPSS, with pen as the experimental unit. At 38d, CON+ and DIC piglets had significantly lower FCR than CON- (1.534a, 1.353b, 1.380b and 1.526ab, for CON-, CON+, DIC and MON, P = 0.021). At 66d, CON+ tended to have lower FCR than CON- (1.613x, 1.541y, 1.560xy and 1.605xy, for CON-, CON+, DIC and MON, P = 0.054). For the overall period, DIC and CON+ piglets had significantly lower FCR than CON- (1.603a, 1.514b, 1.537b and 1.589ab, for CON-, CON+, DIC and MON, P = 0.003), there was also a tendency to lower daily weight gain in MON treatment when compared with CON+ (443xy, 468y, 449xy and 440x g/d, for CON-, CON+, DIC and MON, P = 0.079). Finally, the faecal score showed higher values for DIC and CON+, meaning more consistent faeces (3.71a, 3.93b, 3.84b and 3.82ab, for CON-, CON+, DIC and MON, P = 0.001). The results demonstrated that DICOSAN, administered in feed at the same dosage of lauric acid, achieved better results than monolaurine and CON- and without significant differences with CON+.
