“…However, it can be inferred that acidity caused by the dissociation of butyric acid resulted in a lower deposition of calcium and phosphorus in the bones, considering the result observed for the raw bones, even with the addition of phytase in the diets. Magnago et al (2015) noted that the phytase concentration does not influence the levels of ash and phosphorus in the metacarpals of the animals. Saraiva et al (2009) reported that animals genetically selected for muscle deposition favor weight gain at the expense of bone integrity when subjected to phosphorus deficiency.…”

This study aimed to evaluate the reduction of available phosphorus (Pa) in the diet of weaned piglets using phytase combined with butyric and benzoic acids. A total of 120 piglets with initial weight of 6.7 ± 0.02 kg were used in a randomized block design with six treatments: control; reduction of 0.15% Pa (Pa red); Phytase + Pa red; Phytase + butyric acid + Pa red; Phytase + benzoic acid + Pa red; Phytase + butyric acid + benzoic acid + Pa red; five replicates, with four animals each. The experimental diets had no influence on the fecal scores, Escherichia coli count, or the pH of the digestive tract. An improved villus:crypt ratio was found when the combination of phytase with butyric and benzoic acids was used. The histomorphometry of the jejunum and of the ileum showed no differences with respect to villus height, crypt depth, and villus:crypt ratio. The bones of the piglets fed with a diet containing reduced levels of available phosphorus showed less resistance to fracture. The levels of calcium in the raw bones were lower in the piglets that received a diet containing phytase and butyric acid. Reduced phosphorus deposition was observed in the bones of animals that received the diet containing phytase, butyric acid, and benzoic acid. It is concluded that the inclusion of phytase and butyric and benzoic acids, and their combination, in the diet of weaned piglets does not affect the pH of the stomach, duodenum, jejunum, ileum, cecum, and colon, and does not change the frequency of diarrhea or the E. Coli count. The association of butyric and benzoic acids with phytase in the diet of piglets after weaning improves the villus:crypt ratio of the duodenum. The use of phytase (1000 UF/kg) allows the formulation of diets for weaned piglets with a 0.15% reduction in the level of available phosphorus without damaging the concentration of calcium and phosphorus in the bones and without altering bone resistance.

ResumoRealizou-se este estudo com o objetivo de avaliar a redução do nível de fósforo disponível (Pd) na dieta de leitões desmamados utilizando fitase associada aos ácidos butírico e benzóico. Foram utilizados 120 leitões, com peso inicial de 6,7±0,02kg, distribuídos em delineamento de blocos ao acaso com seis tratamentos: controle; redução de 0,15% de Pd (Pd red); Fitase + Pd red; Fitase + ácido butírico + Pd red; Fitase + ácido benzóico + Pd red; Fitase + ácido butírico + ácido benzóico + Pd red; cinco repetições, com quatro animais cada. As dietas experimentais não influenciaram os escores fecais, a contagem de E. coli e o pH do trato digestivo. Verificou-se melhor relação vilo:cripta com a associação da fitase, com os ácidos butírico e benzóico. A histomorfometria do jejuno e do íleo não apresentaram diferenças para altura de vilosidades, profundidade de cripta e a relação vilo:cripta. Os ossos correspondentes aos leitões alimentados com a dieta com redução do nível de fósforo disponível apresentaram menor resistência à ...

“…Freitas et al (2006) reported a superior consistency of feces from piglets at 21-49 days of age when organic acids were used in the diet. Papatsiros et al (2011) evaluated benzoic acid in the feed of weaned piglets and found a reduction in the severity of diarrhea.…”

“…São proteínas globulares de estrutura terciária ou quaternária que atuam como catalisadores biológicos que aceleram as reações químicas e têm alta especificidade, pois cada tipo de enzima atua sobre um composto ou substrato associado, que se encaixa na enzima específica, de modo que os centros ativos coincidem perfeitamente, sendo capazes de abrir caminhos para sua transformação (complexo enzimasubstrato) (Magnago et al, 2015).…”

RESUMO.O crescimento contínuo da indústria de alimentos resulta em uma grande quantidade de resíduos provindos dos frigoríficos de abate animais. O processamento dessa carne resulta em uma enorme quantidade de resíduos. A quantidade de resíduos produzidos além de ser uma grande perda de coprodutos com amplo potencial para reuso na cadeia produtiva, também causam sérios problemas de gestão, tanto do ponto de vista econômico como ambiental. Um dos resíduos gerados são as farinhas de origem animal (FOA), ingrediente rico em proteína, minerais e fonte energia em para rações de animais monogástricos. O uso de enzimas se torna uma estratégia interessante, pois podem tornar as FOA em ingrediente de maior valor nutricional. A suplementação enzimática beneficia a digestão e a absorção dos ingredientes, e sua adição em farinhas de origem animal pode melhorar a qualidade nutricional das rações e, consequentemente, o desempenho dos frangos. Esta revisão apresenta uma discussão sobre as enzimas uteis para nutrição de animais, principalmente as proteases utilizadas na hidrolise de resíduos proteicos, como as FOA. Palavras-chave: alimentos, avicultura, enzimas, nutriçãoUse of enzymes to increase the nutritional quality of animal meal for feed production.ABSTRACT. The continued growth of the food industry results in a large amount of animal slaughterhouse waste. The processing of this meat results in a huge amount of coproduct. The large amount of waste produced besides being a great loss of material with great potential for reuse in the productive chain, also causes serious management problems, both economic and environmental. One of the residues generated is animal meal (FOA), an ingredient rich in proteins, minerals and energy source in rations of monogastric animals. The use of enzymes becomes an interesting strategy because they can make FOA an ingredient of greater nutritional value. Enzyme supplementation benefits the digestion and absorption of the ingredients, and their addition in animal meal can improve the nutritional quality of the rations and, consequently, the performance of the chickens. This review presents a discussion on enzymes useful for animal nutrition, especially the proteases used in the hydrolysis of protein residues, such as FOA.
