“…This difference was likely due to the quality of dietary ingredients; however, ingredients were not provided in that study, so this cannot be determined. DM digestibility was similar, however, to studies evaluating fish meal and meat meal as the primary dietary protein sources [Funaba et al, 2001, 2002].…”

“…Nitrogen balance has historically been used to determine nitrogen and amino acid requirements of domestic cats during different life stages [NRC, 2006]. It also has been used as a tool to evaluate various dietary protein sources when fed to cats at maintenance [Funaba et al, 2001, 2002, 2005]. Protein quality can alter apparent nutrient digestibility and nitrogen retention in cats.…”

The African wildcat is one of the closest ancestors to the domestic cat and is believed to have similar nutrient requirements, but research is lacking. The objective of this study was to determine the effects of feeding a high-protein extruded kibble diet vs. a raw meat diet on nutrient digestibility, nitrogen metabolism, and blood metabolite concentrations in African wildcats. Five wildcats were randomized onto either a high-protein (>50% crude protein) extruded kibble diet or a raw meat diet. The study was executed as a crossover design, with 21-d periods, consisting of a 16-d adaptation phase followed by a 4-d total fecal and urine collection phase. Cats were housed individually in metabolism cages and fed to maintain body weight (BW). A fresh fecal sample was collected for short-chain fatty acid (SCFA) and branched-chain fatty acid (BCFA) analyses. Blood was analyzed for serum chemistry and leptin concentration. Food intake (as is) did not differ (P>0.05) between diets. Food intake and fecal output (g/d DMB) were greater (P<0.05) when cats consumed the kibble diet. Protein digestibility was higher (P<0.05) when cats were fed the raw meat diet vs. the kibble diet. Nitrogen intake was greater (P<0.05) when cats consumed the kibble diet, and more (P<0.05) nitrogen was present in the feces; however, the percentage of nitrogen retained and nitrogen balance did not differ (P>0.05). Fecal scores, ammonia, SCFA, and BCFA concentrations did not differ (P>0.05) between diets. Fecal butyrate molar ratio was higher (P<0.01) when cats consumed the kibble diet. Blood analyses demonstrated few differences between diets, but alanine aminotransferase activity and bicarbonate were higher (P<0.05) when cats consumed the commercial raw meat diet. Owing to lack of differences, these data indicate that African wildcats can readily utilize a high protein extruded kibble diet, and may be able to replace a commercial raw meat diet.

“…There was no difference (both were 84%) in the protein digestibility of micronized whole soybeans and corn gluten meal in the cat [15]. Protein utilization was not different when corn gluten meal was compared to fish meal [16] and chicken meal in cats [17]. However, meat meal had superior protein utilization when compared to corn gluten meal in cat food [18].…”

This retrospective study used 226 dogs and 296 cats to evaluate whether protein absorption was influenced by species, and within species, what influence increasing the percentage of total dietary protein, as plant protein, had on protein absorption. Each food was evaluated by at least one study with a minimum of six dogs or cats assigned to each study. Dietary inclusion of animal and plant based protein was calculated by analysis of ingredients and dietary inclusion level. Both dogs and cats were able to digest dietary plant protein, with protein digestibility in dogs unchanged as plant protein increased, while in cats, eating dry food, an increase in plant protein, was associated with increased protein digestibility. When individual plant high-concentration protein sources (excluding the protein from whole grains) were evaluated (i.e., soybean meal, soybean protein isolate, corn gluten meal, and rice protein concentrate) there was no response to increasing protein from these sources in the dog. In the cat, there was a significant positive effect on protein digestibility associated with an increasing concentration of corn gluten meal. In summary, as the dietary protein shifted from striated muscle and other animal proteins to plant based proteins, there was no effect in the dog, while in cats, increasing dietary plant protein was associated with increasing protein digestibility (5.5% increase at 50% protein from plants in dry cat food). Protein digestibility of food in dogs and cats is similar, if not enhanced, when the plant protein sources are concentrated from soybeans (soybean isolate, soybean meal), corn (corn gluten meal), or rice (rice protein concentrate).

“…Em estudo realizado por Funaba et al (2001), comparando o efeito de duas fontes de proteína, farinha de peixe e farinha de glúten de milho, não foi observada diferença significativa entre pH urinário dos grupos (6,11 e 6,14 unidades de pH, respectivamente). Os autores sugerem que as fontes proteicas não irão interferir no efeito de acidificação da urina, corroborando com Skoch et al (1991).…”

Desordens do trato urinário felino, em destaque as urolitíases, apresentam alta incidência na casuística clínica. Estudos associam fatores dietéticos como, ingredientes, digestibilidade e composição química, a alteração do volume, pH e densidade da urina e conseqüente indução a formação de urólitos uma correlação altamente significativa entre a composição mineral da dieta e o pH urinário de gatos começa a ser estudada, utilizando a associação entre o balanço catiônico-aniônico da dieta (BCAD) e a regulação do equilíbrio ácido-base do organismo. O BCAD pode ser definido como a diferença entre os cátions e ânions fixos totais presentes na dieta, ferramenta importante para estimar o pH urinário e determinar a faixa de pH que o alimento utilizado favorece, podendo, assim, associar o desencadeamento e a prevenção de urólitos de estruvita e oxalato de cálcio no trato urinário de felinos. Sendo assim, a presente revisão tem como objetivo esclarecer os efeitos da composição nutricional da dieta no pH urinário de gatos. Palavras-chave: excesso de bases; felinos; nutrição; urina.ABSTRACT: Studies for the food development of formulations for pets, look for key components to maintaining healthy way of life and safety of products, including these, elements capable of preventing the risk of certain metabolic disorders associated with diet. Feline urinarytract disorders, highlights the urolithiasis, have high incidence in clinical series. Studies linking dietary factors such as ingredients, digestibility and chemical composition, changing the volume, density and pH of urine and consequent induction training for urolithiasis. A highly significant correlation between the mineral composition of the diet and urine pH of cats began to be studied, using the association between the cation-anion balance of the diet (DCAB) and regulation of acid-base balance of the body. The DCAB can be defined as the difference between the total fixed anions and cations present in the diet, important tool for estimating the urinary pH and to determine the range of pH that favors the food used, thereby linking the trigger and the prevention of struvite and calcium oxalate urolithiasis in the urinary tract of cats. Thus, this review aims to clarify the effects of the nutritional composition of diet on urine pH in cats.
