“…Moreover, the smaller values for the AIDC of protein and amino acids of CM seen in this study were similar to those reported by Mariscal et al (2009) who reported low AIDC for most amino acids, ranging from 40% to 60%. 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).…”

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.

“…The low digestibility of threonine may be partly due to its low rate of absorption in the small intestine (MARISCAL et al, 2009). Furthermore, according to Fan et al (1995), based on the specificity of the endogenous proteases and peptidases, threonine is the last amino acid to be released by enzymatic hydrolysis of proteins.…”

“…The AID of amino acids, energy, and phosphorus was calculated using the following equation: AID = [1 − [(TiD × NI)/(ND × TiI)] × 100 where TiD is the concentration of TiO 2 in the diet; NI is the concentration of the nutrient in the ileal digesta; ND is the concentration of the nutrient in the diet; and TiI is the concentration of TiO 2 in the ileal digesta [ 38 ].…”

This study analyzed the effects of different dietary doses of encapsulated propyl propane thiosulfonate (Pe-PTSO) on the apparent ileal digestibility (AID) of nutrients and productive performance in broilers. A total of 100 one-day-old Cobb 500 were housed in battery cages for 20 days. At 10 days of age, the birds were assigned to one of five diets: negative control (P0), 250 mg/kg of Pe-PTSO (P250), 500 mg/kg of Pe-PTSO (P500), 750 mg/kg of Pe-PTSO (P750), and positive control, nicarbazin–narasin (ION). Titanium dioxide was the external marker, which was added to the diets from day 17 to 20. In the birds fed the P250 diet, there was a significant difference (p ≤ 0.05) in the AID values for amino acids and energy compared to those that consumed the P0 diet. Furthermore, the P250 diet significantly increased (p ≤ 0.05) the average daily weight gain compared to the P0 diet. No significant differences were observed between treatments in average daily feed intake and feed conversion ratio. In summary, the inclusion of 250 mg of encapsulated PTSO per kg in broiler chickens diet improved the digestibility of amino acids and energy, as well as weight gain.

“…Ahmed et al (7) determined the actual and apparent digestibility of extruded canola flour and concluded that extrusion improves apparent digestibility of raw protein, amino acids, raw energy and energy that can be metabolized. Therefore, Mariscal et al (8) en forma extrusada o peletizada pueden ser utilizados en la sustitución parcial de la harina de soya. Ahmed et al (7) determinaron la digestibilidad real y aparente de la harina de canola extrusada y concluyeron que la extrusión mejora la digestibilidad aparente de la proteína cruda, aminoácidos, energía bruta y energía metabolizable, entre tanto, Mariscal et al (8) determinaron los coeficientes de digestibilidad real aparente y estandarizada de la proteína y aminoácidos de la torta de canola peletizada en lechones recién destetados.…”

Objective. Determine the nutritional values of ground (SCI) or extruded (SCE) canola seed and evaluate its use in the performance of piglets from 15 to 30 kg. Materials and methods. Two experimental diets with canola seed were evaluated in a digestibility trial. We used 15 barrows with an initial weight of 19.79±1.43kg, distributed in a completely randomized design. In the performance, four experimental diets were evaluated consisting of a diet with soybean oil added (RAS), one with the of addition of canola oil (RAC) and two oil-free; one with 11% SCI included and one with 6% SCE (RSCE) included. 40 commercial hybrid piglets were used that had 15.25±1.5kg initial body weight, randomly distributed, in four treatments and five replicates; two animals per experimental unit. Results. The digestible energy values for SCI and SCE were 4.197 kcal/kg and 5.234 kcal/kg, respectively. The extrusion process improved the digestibility coefficients. Piglets fed with RSCI showed less daily weight gain (DWG) and F:G ratio. Conclusion. Results suggest that SCE can be included in diets of piglets from 15 to 30 kg until 6% without negatively affecting performance.Key words: Animal performance, anti-nutritional factors, digestibility, economic viability (Source: AGROVOC). RESUMENObjetivo. Determinar los valores nutricionales de las semillas de canola integral molida (SCI) y extrusada (SCE) y evaluar su influencia sobre el desempeño de lechones de 15 a 30 kg. Material y métodos. Se evaluaron dos dietas experimentales con semilla de canola en un ensayo de digestibilidad. Fueron utilizados 15 lechones machos, castrados, con peso inicial de 19.79±1.43kg, distribuidos en un diseño completamente al azar. En el desempeño se evaluaron cuatro dietas experimentales que consistieron de una dieta con adición de aceite de soya (RAS), una con adición de aceite de canola (RAC) y otras dos exentas de aceite; siendo una con la inclusión de 11% de SCI (RSCI) y otra con la inclusión de 6% de SCE (RSCE). Fueron utilizados 40 lechones híbridos comerciales, con peso vivo medio inicial de 15.25±1.5kg, distribuidos en un diseño experimental completamente al azar, con cuatro tratamientos, cinco repeticiones; siendo dos animales por unidad experimental. Resultados. Los valores de energía digestible para SCI y SCE en base seca fueron de 4.197 kcal/kg y 5.234 kcal/ 4407 kg, respectivamente. El proceso de extrusión mejoró los coeficientes de digestibilidad. Los lechones alimentados con RSCI presentaron menor ganancia de peso (GPD) y peor conversión alimentaria (CA). Conclusiones. Los resultados indicaron que la SCE puede ser incluida en la dieta de lechones de 15 a 30 kg, hasta un nivel de 6% sin afectar el desempeño.Palabras clave: Desempeño animal, digestibilidad, factores antinutricionales, viabilidad económica (Fuente: AGROVOC).
