“…Thus, the lack of effect of the acids in the diets may have occurred due to the highly sanitary conditions of the experimental assays. According to Rocha et al (2008), there may be large variability among piglets in the post-weaning stages, with some animals exhibiting more resistance than others, which makes the fecal score results difficult to interpret. 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.…”

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 ...

“…Because organic acids are known to acidify the diet, if the pH of the digesta is reduced, the efficiency of phytase can be improved with the addition of these acids (ROCHA et al, 2008).…”

“…In addition, SB may have acted to reduce the intestinal pH. According to Rocha et al (2008), who tested the efficiency of the use of organic acid in nursery piglets, the lower incidence of diarrhoea may be linked to a greater nutrient digestibility caused by enhanced enzyme activity or protein hydrolysis, resulting from a reduction in the pH of the gastrointestinal tract.…”

In this study, the objective was to assess the growth performance, rectal microbiological profile, serum and immunological standards, and incidence of diarrhoea in piglets in the nursery phase fed diets with and without the addition of coated sodium butyrate 30% (SB). A total of 80 crossbred piglets (40 entire males and 40 females), with an average initial body weight of 9.47 ± 1.03 kg, were distributed in a randomised block design, with four treatments repeated twice in the two blocks and five piglets of the same gender per experimental unit. The treatments comprised a combination of two feeds, formulated based on corn and soybean meal with and without 0.1% SB inclusion as an additional product, and both genders, fed from of the pre-starter I diet. SB did not affect (p > 0.05) the growth performance and rectal microbiological profile of the piglets, but efficiently (p = 0.05) controlled the incidence of diarrhoea. The average values of the characteristics measured in the blood of the piglets were within the normal physiological parameters of the species. The inclusion of SB in commercial feed did not alter the growth performance and rectal microbiological profile of nursery piglets under low sanitary challenge conditions. However, the organic acid efficiently reduced gastrointestinal disorders that cause diarrhoea, with diarrhoea incidence rates of 2.68 and 4.46% for piglets fed with and without the inclusion of the additional organic acid, respectively.
