Effect of decreasing dietary protein level and replacing starch with soluble fibre on digestive physiology and performance of growing rabbits.
At weaning (33 days of age), 246 hybrid rabbits (782 ± 53 g live weight) were divided into six experimental groups and fed ad libitum six iso-ADF diets formulated according to a bifactorial arrangement with two protein levels (152 and 162 g/kg) and three soluble fibre-to-starch ratios (0.2, 0.6 and 1.5), the latter obtained by replacing starch (from 209 to 91 g/kg) with soluble fibre (from 48 t...
متن کاملResponse to dietary digestible energy concentration in growing pigs fed cereal grain-based diets.
Understanding how energy is utilized by the pig, and how the pig responds to changes in dietary energy concentration, is essential information in determining the optimal concentration of dietary energy under farm conditions, which are often highly diverse. The objective of these experiments was to determine how changes in dietary DE concentration, achieved through graded changes in diet composi...
متن کاملInter-relationship of microbial activity, digestion and gut health in the rabbit: effect of substituting fibre by starch in diets having a high proportion of rapidly fermentable polysaccharides.
Caecal microbial activity, digestion and gut health were analysed in the young rabbit, in response to fibre substitution by starch, in diets with high proportions of rapidly fermentable polysaccharides (pectins+hemicelluloses:acid-detergent fibre (ADF) ratio of 1.7). A range of five diets corresponding to a 60 % linear reduction of the ADF level (230 to 92 g ADF/kg) without changes in the fibre...
متن کاملUse of digestible fibre in replacement to available carbohydrates Effect on digestion, rate of passage and caecal fermentation pattern during the growth of the rabbit
The dietary replacement of available carbohydrates (mainly starch) by digestible fibre was assessed on rabbit growth and digestion. Two diets supplying hemicellulose (diet HC) or a mix of hemicellulose and pectins (HC 1 P) were compared to a control diet having a higher starch content, but a similar content in low digested fibre (lignocellulose ADF 5 155 g/kg). Three groups of 17 rabbits were a...
متن کاملStandardized ileal digestible tryptophan-to-lysine ratios in growing pigs fed corn-based and non-corn-based diets.
Two 21-d experiments were conducted to determine the optimum standardized ileal digestible (SID) Trp:Lys in growing pigs fed corn-based diets compared with non-corn-based diets. The primary response variables in both experiments were ADG and plasma urea N (PUN) concentrations with the optimum SID Trp:Lys determined using broken-line analysis. Experiment 1 evaluated the optimum SID Trp:Lys in gr...
