“…La disminución en la digestibilidad ileal aparente de la PC y AA de las diferentes dietas experimentales (Tabla 3), es un resultado directo de sustituir una fuente de proteína altamente digestible (caseína) con una de menor digestibilidad (torta de canola). La reducción en los CDIA de PC y AA cuando TC y TCP fueron incluidas en las dietas experimentales puede ser atribuida a la alta cantidad de fibra (17).…”

RESUMENObjetivo. Obtener los coeficientes de digestibilidad ileal aparente (CDIA) de proteína (PC) y aminoácidos (AA) de torta de canola, en lechones recién destetados. Materiales y métodos. Se utilizaron 24 lechones destetados a los 17 días de edad con un peso de 5.5 kg, a los cuales se les fijó una cánula simple en "T" en el ileon distal. Los lechones recibieron uno de los siguientes tratamientos: Dieta de Referencia (C) elaborada con caseína y almidón de maíz; dietas CTC (caseína-10% de Torta de canola) y CTCP (caseína-10% de torta de canola peletizada). Resultados. Los CDIA de PC y AA de la dieta C fueron superiores (p<0.05), con excepción de algunos aminoácidos de CTCP que tuvieron CDIA similares (p>0.05) a C. No se observó un efecto (p>0.05) del periodo (tiempo posdestete) sobre los CDIA de la PC y AA, exceptuando al aminoácido metionina. Los CDIA del nitrógeno (N) y AA de TCP fueron mayores (p<0.05) que los de TC. Conclusiones. La TCP puede ser incluida en dietas de lechones en un 10% empleando los coeficientes reportados en este trabajo.Palabras clave: Lechones, canola, aminoácidos, digestibilidad ileal. ABSTRACTObjective.

“…Due to its high level of fiber (Bell, 1993; Mińkowski, 2002) and its negative effect on feed intake, RSM is not recommended as the sole protein source in pigs when used to estimate its DE and ME. For this reason, the difference method was used.…”

:Two experiments were conducted to establish a digestible energy (DE) content prediction model of rapeseed meal for growing-finishing pig based on rapeseed meal's chemical composition. In experiment 1, observed linear relationships between the determined DE content of 22 rapeseed meal calibration samples and proximate nutrients, gross energy (GE) and neutral detergent fiber (NDF) were used to develop the DE prediction model. In experiment 2, 4 samples of rapeseed meal selected at random from the primary rapeseed growing regions of China were used for testing the accuracy of DE prediction models. The results indicated that the DE was negatively correlated with NDF (r = -0.86) and acid detergent fiber (ADF) (r = -0.73) contents, and moderately correlated with gross energy (GE; r = 0.56) content in rapeseed meal calibration samples. In contrast, no significant correlations were found for crude protein, ether extract, crude fiber and ash contents. According to the regression analysis, NDF or both NDF and GE were found to be useful for the DE prediction models. Two prediction models: DE = 16.775-0.147NDF (R 2 = 0.73) and DE = 11.848-0.131NDF+0.231GE (R 2 = 0.76) were obtained. The maximum absolute difference between the in vivo DE determinations and the predicted DE values was 0.62 MJ/kg and the relative difference was 5.21%. Therefore, it was concluded that, for growing-finishing pigs, these two prediction models could be used to predict the DE content of rapeseed meal with acceptable accuracy.

“…The reduction in digestibility coefficients of protein and amino acids can be attributed to the high levels of fiber contained in CM compared to other, more digestible protein sources (MINKOWSKI, 2002).…”

“…Therefore, there is a decrease of enzyme activity, and a decrease of the transmembrane absorption of nutrients, along with an increase of the secretion of endogenous proteins. Minkowski (2002) attributed the reduction of AIDC and TIDC of CM to its high fiber content. Likewise, Pozza et al (2003) showed that the canola fiber (NDF) considerably influenced the ileal endogenous losses of nitrogen in pigs, since these compounds are not digested by intestinal enzymes.…”

Three experiments were carried out to determine the nutritional values and evaluate the performance of piglets fed on canola meal. In experiment I, a digestibility assay was conducted using fourteen barrow pigs, with an initial body weight of 20.62±3.30 kg. The evaluated feedstuff was canola meal, with a level of 250 g/kg in the basal diet (corn + soybean meal-based). The experimental unit consisted of one pig, with a total of seven experimental units per diet. The values as (fed basis) of digestible (DE) and metabolizable (ME) energy of canola meal were 2,995 kcal/kg and 2,796 kcal/kg, respectively. In experiment II, ileal digestibility assays were carried out to determine the apparent and true ileal digestibility coefficient and digestible amino acids. Three crossbred pigs were used, with a BW of 38.6±1.98 kg. The treatments consisted of two diets, with a single source of protein (canola meal) and one protein-free diet (OFD). The values of digestible amino acids in canola meal were as follows: lysine: 11.8 g/kg; methionine+cystine: 9.1 g/kg; threonine: 7.9 g/kg; tryptophan: 2.4 g/kg; leucine: 15.7 g/kg; and isoleucine: 8.7 g/kg. In experiment III, 60 piglets (BW= 15.08±0.72 kg to 30.26±2.78 kg) were allotted in a completely randomized design. The treatments consisted of four diets with increasing levels of canola meal (50, 100, 150 and 200 g/kg), six replicates and experimental unit consisted of two pigs. Additionally, a control diet was formulated containing 0.0 g/kg CM. Regression analysis indicates that there was no effect (P≥0.05) of the level of canola meal inclusion on pigs performance. The performance results suggest that it is feasible to use up to 200 g/kg of canola meal in starting pigs diet, without impairing performance and the feeding cost.

No Experimento I foi conduzido um ensaio de digestibilidade total com 14 suínos mestiços de linhagem comercial, machos castrados, com 20,32±3,30 kg de PV inicial. O alimento teste foi o farelo de canola, com o nível de 250 g/kg na ração referência (milho + farelo de soja). Cada suíno constituiu uma unidade experimental, totalizando sete unidades experimentais por ração. Os valores de energia digestível (ED) e energia metabolizável (EM) na matéria natural para o FC foram 2995 kcal/kg e 2796 kcal/kg respectivamente. No Experimento II foi conduzido um ensaio para determinar os coeficientes de digestibilidade ileal aparente e verdadeira e aminoácidos digestíveis. Foram utilizados três suínos canulados com 38,6±1,98 kg de PV. Os tratamentos consistiram em duas dietas, uma dieta contendo FC como única fonte de proteína e uma dieta isenta de
