Effect of probiotics supplementation in diets with different nutrient densities on growth performance, nutrient digestibility, blood characteristics, faecal microbial population and faecal noxious gas content in growing pigs

Abstract

A total of 144 pigs with initial BW of 29.4890.58 kg were used in a 6-wk experiment to evaluate the probiotics supplementation (Enterococcis faecium, 1.0 )10 10 CFU/g) with different nutrient densities in growing pigs. Pigs were randomly allotted to one of four treatments in a 2 )2 factorial arrangement of treatments with two levels of nutrient density and probiotic (0 or 0.1%) according to their sex and BW (nine replicate pens with two gilts and two barrows per pen). Pigs fed the higher nutrient density diets led to a higher (P B0.05) ADG and G:F ratio than those fed low nutrient density diet. The inclusion of probiotic increased (PB0.05) ADG, ADFI, G:F, and the apparent total tract digestibility of DM, N, energy. Dietary high nutrient density led to a higher (PB0.05) faecal H 2 S and NH 3 content, whereas the probiotic supplementation led to a reduced (PB0.05) faecal H 2 S and NH 3 content. An increased faecal lactobacillus concentration was observed with probiotic supplementation. An interactive effect between energy and nutrient density diet and probiotic was observed on the ADG and G:F ratio, faecal lactobacillus, apparent total tract digestibility and faecal noxious gas content. In conclusion, both dietary probiotic supplementation and a high nutrient diet could improve growth performance and nutrient digestibility in growing pigs. The beneficial effect of probiotic supplementation in pigs could be enhanced with the high energy and nutrient density diets.

Effect of a dietary probiotic blend on performance, blood characteristics, meat quality and faecal microbial shedding in growing-finishing pigs

“…1 Faecal score 1-5, in which 1 = hard, dry pellets in a small, hard mass; 2 = hard, formed stool that remains firm and soft; 3 = soft, formed, and moist stool that retains its shape; 4 = soft, unformed stool that assumes the shape of the container; 5 = watery, liquid stool that can be poured (Lan et al, 2016) Furthermore, the dietary treatments did not affect faecal score in pigs. In agreement with the current study, Yan and Kim (2013) and Lan et al (2016) reported that faecal Lactobacillus increased by probiotics supplementation. However, Lan et al (2016) observed a reduction in faecal E. Coli in weaning pigs fed probiotic blend.…”

“…Chen et al (2005) suggested that average bodyweight gain was significantly improved by the addition of probiotics in growing pigs when fed 0.2% of probiotic blend in diet. According to the authors' research findings, Alexopoulos et al (2004) and, more recently, Ross et al (2010) and Yan & Kim (2013) found that dietary probiotics inclusion led to a higher ADG, ADFI, and FCR than in pigs fed no probiotics. As a result, the same authors suggested that the current probiotic blend has the potential to improve productive performance of growing-finishing pigs probably because of increased nutrient digestibility.…”

“…A probiotic mixture consists of two or more live strains at different, and currently, probiotic mixtures have been reported to have better therapeutic effects than a single species Zhang et al, 2017). Probiotics have been reported to improve growth and feed efficiency in piglets (Kyriakis et al, 1999;Yan & Kim, 2013) and in grower-finisher pigs (Meng et al, 2010). However, the use of probiotics to improve meat quality has been questioned, and results in pigs have been inconsistent (Quadros et al, 2001;Česlovas et al, 2005;Meng et al, 2010).…”

Effect of medium chain fatty acids (MCFA) and probiotic (Enterococcus faecium) supplementation on the growth performance, digestibility and blood profiles in weanling pigs

“…Likewise, Inclusion of Enterococcus faecium (10 8 CFU/g) significantly improved growth and feed conversion ratio in weanling pigs (Malloa et al 2010). Our previous studies have confirmed that the efficacy of probiotics in pigs was influenced by dietary energy and nutrient density Yan and Kim 2013).…”

Effects of dietary threonine:lysine ratios on growth performance, blood urea nitrogen, and nitrogen balance in weaned pigs

“…Recently increased focus on environment pollution has led to the requirement of reducing nitrogen excretion by farm animals (Chu et al 2013;Yan & Kim 2013). It has been well accepted that the use of crystalline amino acids (AA) in low crude protein (CP) diets can reduce the nitrogen excretion in swine manure by more than 35% (Le et al 2006;Nyachoti et al 2006).…”
