In vivo measurement of flatulence and nutrient digestibility in dogs fed poultry by-product meal, conventional soybean meal, and low-oligosaccharide low-phytate soybean meal

Abstract

Diets containing < 22.4 g of stachyose/kg and < 2 g of raffinose/kg did not alter digestibility or increase flatulence in dogs.

Effect of β-mannanase on the digestibility of diets with different protein sources in dogs determined by different methodologies1

“…Values for the digestibility of energy and nutrients in the diets containing PBM or SBM obtained in this experiment are consistent with previously reported values, with ATTD of CP of 80.3 to 86.3% for diets with SBM, and between 76.9 and 86.9% for diets based on PBM (Zuo et al, 1996;Clapper et al, 2001;Carciofi et al, 2006;Yamka et al, 2006). The greater ATTD of CP in SBM compared with PBM indicates that CP Table 5.…”

“…Despite not changing fecal texture, the supplementation of 0.01% β-mannanase in the diet containing SBM reduced fecal volume, probably because it increased diet digestibility, as discussed by other authors (McCleary and Matheson, 1986;Choct and Annison, 1992;Bedford, 1993). On the other hand, Yamka et al (2006) did not observe any improvement in fecal texture or reduction in fecal volume in dogs fed a diet containing 30% SBM with 0.50% β-mannanase.…”

“…However, Twomey et al (2003) did not observe any improvement in the ATTD of nutrients and energy in dog diets based on corn or sorghum and supplemented with xylanase, α-amylase, β-glucanase, and other enzymes. Similarly, Yamka et al (2006) did not report any improvement in ATTD of nutrients and energy in dog foods containing 300 g SBM/kg supplemented with 5.0 g β-mannanase/kg.…”

“…The use of exogenous enzymes may reduce the adverse effects of NSP, as demonstrated by the increase of nutrient use of poultry and swine diets rich in β-mannans (Kim et al, 2006;Li et al, 2010). However, results relative to the dietary inclusion of exogenous enzymes in dog foods are inconsistent, and more research in this area is needed (Twomey et al, 2003;Yamka et al, 2006).…”

Minimizing fishmeal use in juvenile California yellowtail, Seriola lalandi, diets using non-GM soybeans selectively bred for aquafeeds

“…Commodity SBM contains 3-5% ST, and 1-2% RA (Choct et al, 2010;Francis et al, 2001). Together with intestinal dysfunction, the colonic fermentation of these non-digestible oligosaccharides can lead to gas production in the gastrointestinal tract of dogs (Yamka et al, 2006) and fish (Kihara and Sakata, 2002). The data in Table 3 demonstrates that the selective breeding program for the two non-GM test ingredients was quite successful in significantly reducing RA and ST levels.…”
