“…Thus, there was no influence on the acceptability of feed by the animals, confirming the results reported by Roque et al (2011) and Maia et al (2010) in palatability tests with additives for cats and dogs respectively, and Santos et al (2011a) when assessing the acceptability of additives in cats. However, contrary to what was reported by Francis (2002), mentioning a reduction in dry matter intake in diets with the inclusion of Yucca schidigera for its astringent and irritating sensation and a possible reduction in gastrointestinal motility.…”

“…It is possible to verify that phosphorus, magnesium, sodium, potassium, iron, manganese, copper and zinc were not affected (P>0.05) in their excretion with the inclusion of additives, corroborating Santos et al (2011a), but the inclusion of Yucca schidigera at concentrations of 250 and 375ppm increased calcium excretion in comparison to the control group (12.36% and 13.12%, respectively), in the same way as the treatments with zeolite increased the excretion of calcium at concentrations of 0.5% and 1.0% (13.8% and 23.17%, respectively). As for the treatments with 125ppm of Yucca schidigera and 0.75% zeolite, they did not differ from the control group, but were below the maximum level (1.0%) of zeolite (17.66% and 14.17%, respectively).…”

“…Moreover, the results of this study are in line with those reported by Çabuk et al (2004) who supplemented 120ppm of Yucca schidigera and 1.5% and 2.5% zeolite to the feed for broilers, and also found no differences in intake and Hauptli and Louvatto (2006), with the inclusion of 160ppm saponins for pigs. percentage of water in the feces, with the inclusion of additives in super premium and standard feed, similar to Santos et al (2011a) when working with cats, and Lowe and Kershaw (1997), when supplementing 250ppm Yucca schidigera for dogs, who found no effect of the additive on the frequency of defecation, fecal output and format, as well as the retention time of fecal volume. Moreover, Hauptili and Lovatto (2006) reported an improvement in the fecal score of pigs.…”

This study aimed to evaluate the effects of adding Yucca schidigera and zeolite (Clinoptilolite) to feed (super premium and standard) for adult dogs on the apparent indigestibility coefficient of minerals. In the first assessment, 21 dogs were used, with average weight of 12.5kg±1.46 in seven treatments in two periods (super premium diet referred to as control and control with the addition of 125, 250, 375ppm Yucca schidigera and 0.5%, 0.75% and 1.0% zeolite). The second assessment was conducted with standard feed, using 21 experimental plots distributed in three treatments (standard diet referred to as control and control with the addition of 375ppm of Yucca schidigera and 1.0% zeolite). The additives did not affect the acceptability of feed and fecal characteristics in both assessments (P>0.05). With the exception of calcium, no minerals were affected by the inclusion of additives (P>0.05) in the experiment with super premium feed. In the assessment with standard feed, calcium as phosphorus and magnesium presented decreased excretion (P<0.05) with the inclusion of additives. It is possible to conclude that the inclusion of additives in the tested concentrations may interfere with the excretion of some minerals in the diet.Keywords: adsorption, pets, clinoptilolite RESUMO Este trabalho teve como objetivo avaliar os efeitos da inclusão de

“…One explanation for this finding was the high concentration of minerals in the diet. According to Santos et al (2011), high mineral content in the diet reflects in a reduction of its absorption by competition for the sites of absorption and complex formation between them. Thus, the consequence would be overestimated pH values to those predicted by equations based on feed composition.…”

Urinary acidifier in diet with high excess base for adult cats

et al. 2013

Maintaining the pH of urine in the ideal range (6.2 -6.4) is of great importance for health promotion in the lower urinary tract of cats. In the economic and standard feed sector this is a major concern, given that the animal urine tends to be alkaline after food consumption of those commercial segments, which predispose to the formation of struvite urolith. Therefore, this study aimed to study the effects of increasing levels of urinary acidifiers (0.0%, 0.3%, 0.6% and 0.9%, on a dry matter base) in feed with high excess base over the acid-basic balance in the organism, apparent digestibility coefficients of nutrients, urinary pH, hydro-electrolyte balance in cats, as well as the adequacy of equations proposed in the literature to estimate the urinary pH. Twenty-four adult cats, males and females were distributed in a completely randomized design, consisting of six animals per treatment. The dry matter content of urine presented a quadratic behavior (p<0,05; y = 9.5863 + 3.2299x + 0.7871x 2 R 2 = 99,91%), HCO 3 -, total CO 2 and excess blood base during the period in which the animals were fed were high when including 0.9% acidifier compared to 0.6% (p<0.05). In contrast, the use of the additive did not change the urinary pH, blood electrolyte concentration, nutrient digestibility, fecal score, food and water intake (p>0.05). The equations proposed in the literature, which use excess of base in feed to estimate urinary pH, overestimated the pH values found in this study. Index terms:Feline, blood gas, pH. RESUMOA manutenção do pH da urina na faixa ideal (6,2 -6,4) é de grande importância para a promoção da saúde do trato urinário inferior de felinos. Em alimentos do segmento econômico e standard essa é uma grande preocupação, já que a urina dos animais tende a ser alcalina, após o consumo de alimentos desses segmentos comerciais, predispondo à formação de urólito de estruvita. Nesse sentido, neste trabalho, objetivou-se estudar os efeitos de níveis crescentes de acidificante urinário (0,0%; 0,3%; 0,6%; e 0,9%, em base de matéria seca) em alimento com elevado excesso de bases sobre o balanço ácido-básico do organismo, coeficientes de digestibilidade aparente dos nutrientes, pH urinário, equilíbrio hidro-eletrolítico de gatos, bem como a adequação de equações propostas na literatura para estimar o pH urinário. Foram utilizados vinte e quatro gatos adultos, machos e fêmeas, distribuídos em delineamento inteiramente casualizado, constituído de seis animais por tratamento. A matéria seca da urina apresentou comportamento quadrático (p<0,05; y = 9.5863 + 3.2299x + 0.7871x 2 R 2 = 99,91%), o HCO 3 -, CO 2 total e excesso de bases sanguíneos, no período em que os animais estavam alimentados, apresentaram-se elevados, na inclusão de 0,9% de acidificante em comparação a 0,6% (p<0,05). Em contrapartida, a utilização do aditivo não alterou o pH urinário, a concentração de eletrólitos sanguíneos, digestibilidade dos nutrientes, escore fecal, consumo de alimento e de água (p>0,05). As equações propostas na literatura...
