Effects of mannan oligosaccharide dietary supplementation on mortality, growth performance and carcass traits in meat Guinea pigs

Abstract

The effects of mannan oligosaccharide (MOS) as a dietary supplement on growth performance, carcass traits and mortality in meat guinea pigs were compared to a commonly used antimicrobial growth promoter (AGP, Zn-Bacitracin). The four experimental treatments were as follow: Control group (no additives); MOS 1 (1.5 g kg−1); MOS 2 (2 g kg−1) and AGP (0.1 g kg−1). The guinea pigs were housed in 40 floor pens containing a deep litter of woodchips (n = 100 animals in each trial; 10 animals per pen). Guinea pigs were all weaned on day 28 and their body weight was measured weekly. All animals were slaughtered at the end of fattening period (day 77) and carcass traits were evaluated. Significant differences against the control group were observed for traits studied (P < 0.05). Between MOS groups and AGP no significant differences were observed. In conclusion, the use of MOS could be a suitable replacement for antibiotic growth promoter to raise guinea pigs.

Effects of mannan oligosaccharides on growth performance, nutrient digestibility, ruminal fermentation and hematological parameters in sheep

“…Supplementation dietary MOS improved growth performance and gut health in broiler chickens ( Soumeh et al, 2019 ), and increased feed utilization and amino acid digestibility in White Pekin ducks ( Park, Jung & Carey, 2019 ), as well as improved growth performance and modulation of intestinal microbial populations in Japanese quail ( Hazrati, Rezaeipour & Asadzadeh, 2019 ). Supplementation dietary MOS maintained the normal intestinal health of rats ( Yazbeck et al, 2019 ), and effectively replaced antibiotics as growth promoters in raising guinea pigs ( Minguez, Ingresa-Capaccioni & Calvo, 2019 ). Additionally, supplementation dietary MOS improved the growth performance, antioxidant capacity and immunity of aquatic animals ( Lu et al, 2019 ; Meng et al, 2019 ; Mohammadian et al, 2019 ; Widanarni et al, 2019 ).…”

Comportamiento productivo de cuyes (Cavia porcellus L.) en crecimiento suplementados con prebióticos y probióticos naturales

“…Guevara y Carcelén (2014), determinaron que el probiótico suplementado en cuyes evaluados, causó un efecto positivo en su comportamiento productivo. Mínguez et al, (2019) encontraron un efecto significativo en el uso de prebiótico (p < 0.05), indicando que podría reemplazar a un promotor de crecimiento en la producción de cuyes. Guevara et al, (2016), encontraron mejores parámetros productivos en cuyes suplementados con 150 y 300 ppm de inulina como prebiótico.…”
