Effects of supplementing growing-finishing pig diets with Bacillus spp. probiotic on growth performance and meat-carcass grade qualitytraits

Abstract

Seventy five pigs [(Landrace × Yorkshire) × Duroc] with an initial body weight of 23.3±1.40 kg were used in the present study to investigate the influence of supplementation of a Bacillus spp. combination as probiotic (0%, 0.01%, and 0.02% with basal diet) in growing-finishing pig diets on performance parameters with a feeding trial period of 16 weeks. Growth performance was analyzed at the start and at weeks 6, 12, and 16 of the experimental period. The entire experiment using probiotic supplementation in the diet revealed significant differences in average daily gain and gain:feed, but no effects on average daily feed intake. The result showed significant effects on digestibility of dry matter (0.002), nitrogen (0.069), and energy (0.099) at week 16; and number of fecal Lactobacillus (0.082, 0.041), E. coli (0.097, 0.052), and blood glucose (0.001, 0.049) at weeks 6 and 16. Dietary supplementation with Bacillus spp. probiotic resulted in a significant linear effect on sensory evaluation of meat color, drip loss at day 3, and carcass weight in pigs. In contrast, there was no significant difference in blood metabolic profiles and noxious gas emissions in this experiment. Dietary combination of Bacillus spp. can be used as a probiotic for enhancing the growth performances and carcass quality of growing-finishing pigs.

Inclusion of dietary multi-species probiotic on growth performance, nutrient digestibility, meat quality traits, faecal microbiota and diarrhoea score in growing–finishing pigs

“…This may be due to the microbiota balance in the gut being optimised, resulting in an improved utilisation of nutrients and reduced diarrhoea score. In this study, modest but statistically significant effects on Lactobacilli and E. coli counts were observed in faecal after pigs were fed with supplemented MSP, which are in agreement with Balasubramanian et al (2016) and Yan and Kim (2013) who reported that inclusion of dietary probiotic increased the faecal Lactobacillus and decreased E. coli counts in growing-finishing pigs. Thus, it may the reason behind reduced diarrhoea incidence in pigs.…”

“…According to Meng et al (2010), MSP could increase the ATTD in the growing phase, but not in the finishing phase of pigs. Moreover, Balasubramanian et al (2016) reported that Bacillus spp. probiotic in diets significantly increased nutrient digestibility in growing-finishing pigs.…”

Bacillus licheniformis-Fermented Products Reduce Diarrhea Incidence and Alter the Fecal Microbiota Community in Weaning Piglets

“…The abundance of Lactobacillus species and Bifidobacterium species were increased in the feces of growing pigs fed Bacillus species-based probiotics [26]. A linear trend of Bacillus species-based probiotics supplementation on the number of Lactobacillus species was found [21]. Dietary supplementation of B. licheniformis in combination with B. subtilis reprograms the microbiota of weaning piglets challenged with F4 positive enterotoxigenic E. coli.…”

“…A previous study demonstrated that a dietary combination of Bacillus species-based probiotics, containing B. lichenformis, B. coagulans, and B. subtilis, improves the growth performance in growing-finishing pigs [21]. It has been demonstrated that supplementation of B. licheniformis in combination with B. subtilis increases the growth performance and reduces the morbidity and mortality rates associated with diarrhea in weaning piglets [22].…”

Effect of SuperYea and Mixture of SuperYea with Single, Double and Multi of Microbes on Growth Performance and Nutrient Digestibility in Growing Pigs

“…As result animals may have increased growth performance because they eat more. We also investigated whether a specific synbiotic, a combination of SuperYea and multi-strain probiotic have a higher effect on body final weight gain, body weight gain and average daily gain compared to other treatments for growing pigs (p<0.05) but average daily feed intake had not significant(p>0.05) as similarly with [5,[17][18][19] were studied of supplementation of yeast culture (YC) and modified yeast culture [YC+cell wall product (CWP) containing mannam-oligosaccharide] were increased body weight gain (BW) compared to control (p<0.05) but the average dairy feed intake (ADFI) had not significant among treatments (p>0.05). The supplementation of a prebiotics did not significantly affect growth.…”
