Optimal saponin-aluminosilicate blend
A unique product is obtained (Excential Sapphire Q, Orffa Additives BV) by combining Quillaja saponaria extract with an activated aluminosilicate. This optimal saponin-aluminosilicate blend will not only support resilience against coccidiosis but will also provide excellent binding of bacterial toxins. The activated aluminosilicate has been shown to bind to alpha and NetB exotoxins, important virulence factors produced by the Clostridum perfringens pathogen. Therefore, the functional activity of this unique blend has a broader spectrum towards necrotic enteritis.
Reduced oocyst shedding
A recent trial carried out at Virginia Tech (USA) showed that the combination of Quillaja saponins and an aluminosilicate reduced the adverse effects of a coccidiosis challenge on the performance in broiler chickens. The challenge consisted of used litter containing oocysts shed by seeder birds (natural infection model). In total, 1152 one-day-old Ross 708 male broilers were allocated to 12 replicate pens of 24 broilers. The trial consisted of four treatments: a positive control reared on clean litter, with no additive or coccidiostats added to the feed (PC); a negative control reared on used litter, with no additive or coccidiostats added to the feed (NC); a negative control reared on used litter, with a coccidiostat (salinomycin) added to the feed (NC + sal); a negative control reared on used litter, with the addition of Excential Sapphire Q, Orffa Additives BV (Quillaja saponaria extract on an aluminosilicate carrier) on top of the diet during the whole rearing period (NC + SapQ). The number of Eimeria oocysts shed by broilers challenged with coccidiosis was similar for the broilers that received salinomycin, an anticoccidial, and the broilers that received the saponin-aluminosilicate blend (Figure 1). Furthermore, the addition of the saponin-aluminosilicate blend improved final body weight (BW) at 42 days of age and the feed conversion ratio (FCR) between 0 and 42 days of age of coccidiosis infected broilers (used litter) to a similar level as broilers reared on clean litter (PC) (Figure 2). Improved feed efficiency and reduced severity of Eimeria infection in broilers will directly translate into higher farm income.
The distinctive combination of a highly concentrated and standardised Quillaja saponaria extract (with a high concentration of triterpenoid saponins) and activated alumino-silicate results in a suitable blend to complement present coccidiosis control strategies and further promote resilience to infection in broilers.
