Previous issue date: 2015-03-26 / Objetivou-se com este estudo avaliar os efeitos do farelo do baga?o de caju (FBC) como ingrediente de ra??es em programas de restri??o alimentar sobre as caracter?sticas da carca?a, qualidade da carne, peso dos ?rg?os e morfometria intestinal de su?nos machos castrados e f?meas. Foram utilizados vinte e quatro su?nos mesti?os (machos castrados e f?meas) com peso m?dio inicial de 57,93 ? 3,67 kg/PV. O delineamento experimental foi o de blocos casualizados em um esquema fatorial 3x2, sendo tr?s n?veis (0%, 15% e 30% de FBC), dois sexos e quatro repeti??es. Totalizando 24 parcelas. Os tratamentos foram compostos por uma dieta basal (DB), contendo milho, farelo de soja e n?cleo comercial para su?nos em termina??o, sendo suplementada com diferentes n?veis de FBC. No final do per?odo experimental os animais foram abatidos para a avalia??o da carca?a, qualidade da carne, Peso Absoluto (PA) e Peso Relativo (PR) dos ?rg?os e estudo morfom?trico de fragmento do intestino delgado. A inclus?o de FBC nas dietas n?o afetou a qualidade das carca?as das f?meas, mas interferiu positivamente nas carca?as dos machos castrados, aumentando o rendimento de carne na carca?a resfriada e reduzindo a espessura de toucinho, sem afetar o perfil dos ?cidos graxos. Observou-se aumento do peso dos ?rg?os e volume parcial da mucosa absortiva (Vv) das f?meas. Quando se comparou os resultados entre sexo, os machos apresentaram maior peso do f?gado e densidade de superf?cie da mucosa absortiva (Sv). Neste contexto, o FBC apresentou-se como um ingrediente a ser utilizado em programas de restri??o alimentar qualitativa para su?nos na fase de termina??o. / 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.
