The nutritive value of 2 types of sun-dried olive cake (OC), extracted traditionally (COC) or with a 3-phase olive cake (TPOC), was studied for the growing rabbit. Four diets containing 10 or 20% of COC (COC10 and COC20) or of TPOC (TPOC10 and TPOC20) in substitution for a basal diet were compared to a control diet without OC (OC0). Five groups of 12 rabbits were fed one of the 5 diets ad libitum from weaning (35 d) to 46 d of age. The faecal digestibility was individually measured between 42 and 46 d of age. COC and TPOC are high fibre and lignin sources, with 707 and 787 g/kg dry matter (DM) of neutral detergent fibre, 530 and 554 g/kg DM of acid detergent fibre, 242 and 243 g/kg DM of acid detergent lignin, respectively. Replacing 20% of basal diet by COC sharply reduced (P<0.001) the digestibility of energy and crude protein from 0.67 to 0.54, but that of protein only moderately (from 0.80 to 0.76). The same effect was observed with the incorporation of 20% of TPOC. The digestible energy (DE) content of COC and TPOC were calculated by regression and were 3.24±0.41 and 2.94±0.52 MJ DE/kg DM respectively, corresponding to an apparent faecal digestibility of the gross energy of 0.14 (COC) and 0.13 (TPOC). The apparent faecal digestibility of the crude protein of COC was 7 units higher than TPOC (0.44 vs. 0.37) and the digestible protein (DP) content was 20% higher (27.9±4.2 g vs.22.4±6 g DP/kg DM). Olive cake could be considered as a high fibre source with a low protein and energy content for the growing rabbit.
This study was undertaken to evaluate the effect of food diet supplemented consisting of 30% cereal bran (barley and wheat) on the development of “wistar” rats. Sixty six male “wistar” rats with a mean weight of 173 ± 5g were examined for a period of three months. The experimental diets include a standard diet (S), hypercaloric diet (H), enriched diet with wheat bran (WB) or enriched diet with barley bran (BB). A significant increase (P<0.05) in weights was noted especially in rats under hypercaloric diet (H). Glycemia, total cholesterol, triacylglycerols and LDL-C increased in rats under hypercaloric diet and decrease with diets enriched with wheat and barley bran.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
