“…Lowe & Kershaw (1997) also found no changes in hematological counts. For rats, Preston et al (1987) have found that the use of The initial concentration of total ammonia decreases as zeolite is added; however the data behavior presented in this study are supported by the finding of Sonnenholzner (2004), which showed that the adsorbents are more effective when there is high concentration of solute related to the adsorbent. The authors found, by including 1 g zeolite, the removal of total ammonical-N at 1.53 mg/g.…”

“…The reduction in the odor can be achieved through the use of raw materials with high digestibility. This effect can be enhanced by the use of additives such as Yucca schidigera extract, which inhibits the urease by the extract's saponin fraction (Preston et al, 1987) and is an alternative source of fiber, which helps in reducing the intestinal transit (McFarlane & Metheney, 1998); or with the inclusion of zeolite (hydrated aluminum silicates), which has properties such as adsorption of gas, fumes and water (Pond et al, 1995) that, somehow, will act on the mechanisms that contribute to the bad odor in feces. Currently, there is a great scientific interest in the usage of both Yucca schidigera extract (YSC) and zeolite, additives classified as odor reducers (Anfalpet, 2008), due to their extensive range of functional properties.…”

-The effect of the additives Yucca schidigera (YSC) and zeolite (clinoptilolite) on digestibility, fecal texture and odor, blood parameters and urine pH of domesticated felines was evaluated. The experiment was conducted in a randomized block design, with twenty-one cats, in two periods, distributed in seven treatments: moist commercial feed (control); control + 125, 250 and 375 ppm YSC; and control + 0.5; 0.75 and 1.0 % zeolite. No differences were observed between the diets regarding apparent digestibility coefficients of nutrient, energy, urine pH or blood parameters. However, levels of 0.5 and 0.75% zeolite were effective both in reducing odor (R 2 = 96.39) and for fecal texture (R 2 = 99.63), showing a quadratic pattern for these variables.Levels of 125 and 375 ppm YSC were also efficient in reducing fecal odor; however they did not adjust to regression. Levels of 0.5% and 0.75% zeolite significantly reduce odor of feces and increase fecal texture when added to commercial feed for cats.

“…Week of feeding had no effect on fecal TKN (P 5 0.585), urinary TKN (P 5 0.848), or urinary NH 4 1 -N (P 5 0.747; Table 3). Yucca extract was once believed to exert its effects on ammonia volatilization through inhibition of urease by its saponin fractions (Preston et al, 1987). However, because the magnitude of its effects are much too great to be completely explained by its only weak inhibitory properties (Killeen, 1995) and because liberation of radioactively labeled carbon dioxide of urea origin by jack bean urease was not impaired by yucca (Headon et al, 1991), the mode of action of yucca extract is now believed to be through a binding or conversion of ammonia (Headon et al, 1991).…”

Two swine feeding trials were conducted (initial body weight = 47 ± 2 and 41 ± 3 kg for Trials 1 and 2, respectively) to evaluate reduced crude protein (CP) and yucca (Yucca schidigera Roezl ex Ortgies) extract-supplemented diets on NH 3 emissions. In Trial 1, nine pigs were offered a corn-soybean meal diet (C, 174 g kg −1 CP), a Lys-supplemented diet (L, 170 g kg −1 CP), or a 145 g kg −1 CP diet supplemented with Lys, Met, Thr, and Trp (LMTT). In Trial 2, nine pigs were fed diet L supplemented with 0, 62.5, or 125 mg of yucca extract per kg diet. Each feeding period consisted of a 4-d dietary adjustment followed by 72 h of continuous NH 3 measurement. Urine and fecal samples were collected each period. Feeding the LMTT diet reduced (P < 0.05) average daily gain (ADG) and feed efficiency (G:F) compared to diet L. Fecal N concentration decreased with a reduction in dietary CP, but urinary ammonium increased from pigs fed diet LMTT (2.0 g kg −1 , wet basis) compared to those fed diet C (1.1 g kg −1 ) or L (1.0 g kg −1 ). When pigs were fed reduced CP diets NH 3 emission rates decreased (2.46, 2.16, and 1.05 mg min −1 for diets C, L, and LMTT). Yucca had no effect on feed intake, ADG, or G:F. Ammonium and N concentrations of manure and NH 3 emission rates did not differ with yucca content. Caution must be executed to maintain animal performance when strategies are implemented to reduce NH 3 emissions.

“…Esses benefícios também podem ser alcançados com a inclusão na dieta de aditivos como o extrato de Yucca schidigera, que inibe a urease pela fração de saponinas do extrato (Preston et al, 1987) e é fonte alternativa de fibra, auxiliando na redução no trânsito intestinal (McFarlane et al, 1988a), ou com a inclusão de zeólitas (aluminiossilicatos hidratados), que têm propriedades de absorção de gases, vapores e água (Pond et al, 1995).…”

RESUMO -Objetivou-se com este trabalho determinar a interferência dos aditivos extrato de Yucca schidigera e zeólitas (Clinoptilolita) na palatabilidade e digestibilidade de rações comerciais e avaliar sua capacidade de redução do odor das fezes e melhora da consistência fecal de cães. Utilizaram-se cães adultos da raça Beagle com peso médio de ±12,51 kg em três experimentos, todos em delineamento inteiramente casualizado. No teste de palatabilidade, realizado nos dez dias iniciais, utilizaram-se 16 animais distribuídos em duas dietas (controle, com 1,00% de zeólita; e controle + 375 ppm de Yucca schidigera) e, no teste de redução de odor das fezes, realizado nos seis dias posteriores, utilizaram-se 14 animais distribuídos em sete dietas (uma controle e outras seis, formuladas a partir da dieta controle, porém contendo Yucca schidigera (125, 250 ou 375 ppm) ou zeólitas (0,50; 0,75; ou 1,00%). Essas dietas foram utilizadas também no teste de digestibilidade e escore fecal, realizado com 21 animais durante 20 dias. A inclusão desses aditivos na dieta não prejudica a palatabilidade nem a digestibilidade de matéria seca, proteína bruta, extrato etéreo e energia bruta do alimento fornecido. Os níveis de 0,75% e 1,0% de zeólitas reduz significativamente o odor das fezes e aumenta a consistência fecal quando adicionados a rações comerciais para cães.

It was used Beagle breed adult dogs with average weight of ±12.51 kg in 3 experiments, all of them in a completely randomized design. In the palatability test, performed on the first ten days, it was used 16 animals distributed in two diets (control diet, with 1.00% zeolite and control diet + 375 ppm Yucca schidigera) and, on reduction of fecal odor test, performed on the six following days, it was used 14 animals distributed in seven diets (one control and the other six formulated from control diet, containing Yucca schidigera (125, 250 or 375 ppm) or zeolites (0.50; 0.75 or 100%, however). These diets were also used in the digestibility and fecal score trials performed with 21 animals during 20 days. The inclusion of these aditivies in the diet does not harm the palatability neither digestibility of dry matter, crude protein, ether extract and gross energy of the supplied food. Levels of 0.75% and 1.0% of zeolites significantly reduce odor of feces and increase fecal consistency when added to commercial rations for dogs.
