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.

“…Their composition and their physico-chemical properties, explain this effect [14,16,25,29]. The presence of fibres and their properties such as viscosity or water-holding capacity increase the turnover of the epithelial cells but also mucus excretion, pancreatic secretions or the microflora [30][31][32][33]. A feed-back effect, coming from the volatile fatty acids produced in the colon on the small intestine epithelial cell proliferation is also suspected [34].…”

-The present study was conducted to evaluate whether bodyweight and the micronisation of dietary fibre affect the endogenous nitrogen and amino acid losses (ENL and EAAL) in pigs. The effect of the micronising process was tested by providing pigs with 90 g DM·kg -1 BW 0.75 of a N-free diet supplemented with isolated pea inner fibres, presented in native or micronised form and with a water-holding capacity of 12 and 4 g water·g -1 DM, respectively. ENL and EAAL were measured on pigs weighing 24, 62 and 105 kg. In all cases, daily ENL increased linearly (P < 0.05) with BW, for the majority of the AA and total N. As BW increased, daily ENL, total EAAL and the majority of EAAL increased linearly independently of micronisation (P < 0.05). When expressed per kg DMI, total EAAL and the majority of each EAA decreased curvilinearly and reached nadir at around 100 kg BW. For ENL expressed per kg DMI, micronisation resulted in a curvilinear decrease with increasing BW, as compared to a linear decrease for pigs fed the native pea fibre diet (non-micronised). Micronisation of pea inner fibres did not decrease ENL or EAAL daily, except for proline. When the losses were expressed as g·k -1 g DMI, micronisation did not decrease ENL but decreased (P < 0.05) endogenous losses for a majority of AA as well as for total AA. The results suggest that small pigs excrete more endogenous N per kg DMI than large pigs and that pea fibre micronisation reduces EAAL but not ENL when expressed per kg DMI. pig / endogenous loss / ileum / amino acid / nitrogen

“…Chitooligosaccharide are generally produced by hydrolysis of the chitosan polymer through a variety of methods, which includes chemical, enzymatic or physical process of hydrolysis (Kittur et al, 2005). Compared with the intact high molecular weight (MW) chitosan, COS generally have a greater solubility and often a higher level of biological activity (Jin et al, 1994;Kim and Mendis, 2006).…”

An experiment (complete randomised design) was conducted to investigate the effects of supplementing different molecular weights (MW) of chitooligosaccharide (COS) on pig performance, selected microbial populations and nutrient digestibility post-weaning. A total of 396 weaned piglets (24 days of age, 7.3 kg 6 (s.d.) 1.7 kg live weight) were assigned to one of six dietary treatments (22 replicates/ treatment) for a 33-day experimental period. The dietary treatments were as follows (1) control diet (0 ppm COS), (2) control diet plus ,1 kDa COS, (3) control diet plus 3 to 5 kDa COS, (4) control diet plus 5 to 10 kDa COS, (5) control diet plus 10 to 50 kDa COS and (6) control diet plus 50 to 100 kDa COS. The COS were included at 250 ppm in the diets. There was no significant effect of dietary treatment on piglet performance during the starter period (days 0 to 18; P . 0.05). However, there were quadratic responses in both daily gain (P , 0.05) and gain to feed ratio (P , 0.05) to the increased MW of COS inclusion during the weaner period (days 18 to 33) with all COS-supplemented treatments improving daily gain and gain to feed ratio compared with the control. There was a quadratic response in faecal scoring to the increased MW of COS inclusion from days 0 to 7 (P , 0.001), days 7 to 14 (P , 0.001) and during the overall experimental period (P , 0.01) with all the COS-supplemented treatments having an improved faecal score compared with the control. During the weaner period, there was a cubic response in lactic acid bacteria and Escherichia coli populations as the MW of COS increased (P , 0.05). The 5 to 10 kDa and 10 to 50 kDa COS increased lactic acid bacteria populations compared with the control, whereas lactic acid bacteria populations decreased at 50 to 100 kDa. The 5 to 10 kDa, 10 to 50 kDa and 50 to 100 kDa COS decreased E. coli populations compared with the control. There was a cubic response in the apparent total tract digestibility of dry matter (DM; P , 0.01), organic matter (OM; P , 0.01), ash (P , 0.01), nitrogen (N; P , 0.01) and gross energy (GE; P , 0.01) to the increased MW of COS inclusion during the weaner period. The 5 to 10 kDa COS had a higher apparent total tract digestibility of DM, OM, ash, N and GE in comparison to the control, whereas the apparent total tract nutrient digestibility of these nutrients decreased at 10 to 50 kDa. The current results indicate that the MW ranges of 5 to 10 kDa and 10 to 50 kDa COS decreased E. coli numbers while increasing nutrient digestibility of the diets.
