T1 Influence of lecithin emulsifier on the utilisation of nutrients and growth of piglets after weaning JF Czech Journal of Animal Science YR 2005 VO 50 IS 10 SP 459 OP 465 DO 10.17221/4245-CJAS UL https://cjas.agriculturejournals.cz/artkey/cjs-200510-0003.php AB The influence of supplementation of a lecithin emulsifier (0.1%) to the feed mixture for piglets after weaning was studied. 16 piglets in the control group (C - without lecithin) and 16 piglets in an experimental (E) group were monitored in three replications in a 28-day experimental period. We observed higher digestibility of monitored nutrients in the experimental group (crude fat: C = 66.28 ± 12.11, E = 69.75 ± 9.85%, crude protein: C = 78.72 ± 5.47, E = 82.17 ± 2.23%, crude fibre: C = 56.70 ± 12.85, E = 59.10 ± 12.04%, nitrogen free extract: C = 86.67 ± 3.32, E = 87.75 ± 3.00%, ash: C = 63.63 ± 11.59, E = 65.73 ± 10.35%). Statistically insignificantly higher daily average gain (C = 374.1 ± 107.0, E = 399.1 ± 104.7 g) of experimental groups and a lower feed conversion ratio (C = 2.285 ± 0.416, E = 1.768 ± 0.048 kg/kg) were found out. It was also confirmed in an additional field experiment (C = 279, E = 312 piglets from birth to 71 days of age) where average daily gain weight was 270 g in control and 290 g in experimental group. The influence of lecithin on the occurrence of haemolytic strains of Escherichia coli was not proved. This experiment confirmed a positive effect of the lecithin emulsifier supplement on the efficiency of piglets.
