Two experiments (E) were carried out with the objective of evaluating the effects of fumaric acid and carbo-amino-fosfo-quelato of calcium diets of weaned pigs on performance (E1) and intestinal morphology (E2). A total of 96 and 32 pigs with initial mean weights of 5,66 kg ± 0,44kg and 5,34 ± 0,45kg , in E1 and in E2, were used respectively. Randomized block designs were used in both experiments, with a 2 X 2 factorial arrangement in E1 and a 2 X 2 X 2 factorial arrangement in E2. No interaction between acidifier, source of calcium and phosphorus were found for the variables studied in the two experiments. No treatment effects were found on daily feed intake in evaluating periods. Feed conversion from 0 to 17 days was better (P<0.05) when inorganic sources of Ca and P were fed; however, no difference was observed in other periods. The averages of villus height (AV), crypt depth (PC), AV: PC relationship and mucous membrane of the duodenum and of the jejunum didn’t differ among treatments. Considering the total nursery period, no benefit was found in using an acidifier, however the carbo-amino-fosfo-quelato of calcium studied may replace the inorganic sources in the diets of piglets, with no damage to performance and to intestinal morphology.

The objective of this study was to evaluate the effects of the use of cashew bagasse bran (CBB) as food ingredient in qualitative feed restriction programs on the carcass traits, meat quality, organs weight and intestinal morphometry of barrows and gilts. Twenty – four crossbred pigs were used (12 barrows and 12 gilts) with an average initial body weight of 57.93 ± 3.67 kg/LW. The experimental designs was in randomized blocks 3x2 factorial arrangement with three level (0%, 15% e 30% CBB), two genders (barrows and gilts) and four repetition. A total of twenty-four instalments. The treatments were composed of basal diet (BD) formulated with corn, soybean meal and commercial base mix for finishing pigs, being containing different levels of CBB. At the end of the trial period the animals were slaughtered for the evaluation of the meat quality, traits carcass, Absolute Weight (AW) and Relative Weight (RW) of the organs and morphometric study of small intestine fragment. The inclusion of (CBB) in the diets did not affect the traits carcass of gilts, but interfered in the traits carcass of the barrow positively, increasing the yield of meat into cold carcass and reducing the thickness of subcutaneous fat, without affecting the fatty acid profile. However, we observed increased weight of organs and partial volume of absortiva mucosa of gilts. In the comparison between sex was observed a greater liver weight (AW) and (RW), and surface density of absortiva mucosa of barrow. The use of CBB was considered as ingredient to be used in programs of qualitative feed restriction for finishing pigs.

A pesquisa foi conduzida com o objetivo de comparar duas técnicas de enterorrafias no cólon descendente de eqüinos, uma aposicional e outra invaginante, utilizando-se de avaliações morfométricas. As intervenções cirúrgicas foram executadas em 15 eqüinos adultos sadios, pelo flanco esquerdo, sob anestesia geral inalatória. As enterotomias foram realizadas na tênia antimesentérica do cólon descendente e as enterorrafias foram feitas com fio de poliglactina 910 n° 0. Os eqüinos foram distribuídos aleatoriamente em cinco grupos de três animais cada e submetidos à eutanásia aos três, sete, 14, 21 e 35 dias de pós-operatório para colheita de segmentos intestinais dos locais das enterorrafias para análise morfométrica. Com o auxílio de analisador de imagens, foram contados os números de neutrófilos, células mononucleares e eosinófilos ao redor do fio de sutura. Na contagem de neutrófilos, houve diferença (P = 0,05) entre as enterorrafias, com maior número na aposicional. Quanto aos mononucleares, observou-se diferença (P = 0,01) na interação entre os dias de pós-operatório e as enterorrafias. Não foram observadas diferenças (P > 0,05) na contagem de eosinófilos. Concluiu-se que a enterorrafia invaginante causou reação inflamatória de menor intensidade que a aposicional, sendo a opção preferencial para uso neste órgão.
