Effects of Enterococcus faecium SLB 130 probiotic on the performance of weaning pigs

This study aims to analyse the effect of an Enterococcus faecium SLB 130 probiotic on the growth performance, nutrient digestibility, and blood profile in weaning pigs. A total of 200 weaning pigs were taken and assigned to 1 of 5 dietary treatments according to their average initial body weight and sex in a complete randomised block design. The experimental diets were as follows: CON - basal diet, and the basal diet supplemented with 2.5 × 10⁵ cfu/g (TRT1), 1.29 × 10⁶ cfu/g (TRT2), 1.15 × 10⁷ cfu/g (TRT3), and 1.1 × 10⁸ cfu/g (TRT4) of E. faecium for 6 weeks. Pigs fed a diet containing an E. faecium SLB 130 probiotic supplement significantly increased (P < 0.05) the body weight, average daily gain, and average daily feed intake at weeks 1, 3, 6, and the overall period. In addition, the E. faecium SLB 130 (P < 0.05) supplement group pigs showed an increased gain to feed ratio at week 6 and the overall experimental period. Moreover, the dietary inclusion of the E. faecium SLB 130 probiotic supplement linearly increased (P < 0.05) the nutrient digestibility of the dry matter and nitrogen, however, there were no improvements observed on weanling pigs' blood profile. In summary, the inclusion of an E. faecium SLB 130 probiotic additive in the weanling pigs' diet would be beneficial to enhance their growth performance and nutrient digestibility.
