Dietary Sugar Beet Tops and Prebiotic Effect on Nutrient Digestibility, Caecal Activity and Organ Histology of Weaning Rabbits

Abstract

The current study was designed to evaluate the effect feeding weaning rabbits sugar beet tops (SBT) with prebiotic on digestibility of nutrients and caecal microbial activity, volatile fatty acids estimation and organs histology. Fifty four 6-week-old unsexed weaning NZW rabbits were randomly distributed in a factorial (3 × 2) design to six equal groups. Sugar beet tops (SBT) was used at levels 0.0, 20 or 30% of the diet instead of the percent of alfalfa hay in the control diet in presence of 1.0 g/kg diet or absence of prebiotic (Perfect). Digestibility coefficients of dry matter (DM), crude protein (CP), ether extract (EE) and NFE of 12-week old NZW rabbits were improved by feeding SBT-containing diets. Dietary SBT level had no significant effect on pH value, TVFA,s and NH 3 -N values for caecum content of 12 weeks old NZW rabbits, however, total bacteria, E. coli and lactobacillus counts were significantly affected. Feeding SBT-containing diets did not alter plasma concentrations of AST and ALT of 12-week-old rabbits. Dietary prebiotic had a positive effect on the digestibility coefficients of DM, OM, CP, EE, CF and NFE of growing rabbits. Added prebiotic had a positive effect on caecal fermentative activities and caecal microbial activity of growing rabbits. The pH value, ammonia-N level, total bacteria and lactobacillus counts of rabbits fed prebiotic-supplemented diets were significantly higher but E. coli count was reduced as compared to control ones. This study concluded that sugar beet tops can be safely used in rabbit diets up to 30% instead of alfalfa hay.

Replacement of Dietary Yellow Corn by Wheat Bran With or Without Multi-Enzymes or Prebiotic Supplementation on Nutrient Digestibility and Blood Parameters in Growing Rabbits

“…Abo El-Maaty et al (2018) reported that dietary prebiotic had a positive effect on the digestibility coefficients of DM, OM, CP, EE, CF and NFE of growing rabbits. They also noticed that added prebiotic had a positive effect on caecal fermentation activities of growing rabbits.…”

Effect of a Diet Based on Biotransformed Sorghum on Rabbit Intestinal Morphology and Fecal Fiber Composition

“…The effect of SSF sorghum on ce be a response to increased nutrient availability due to sorghum pre-hydr digestion retention time in the caecum is relatively short, it is mainly the fermentable cell wall polysaccharides (such as the hemicellulose fraction) tha at this point, playing a key role not only in rabbit digestive processes but gestive health and sanitary status of rabbits [7,37]. T1-supplied rabbits exh crypts in all gut tracts except for the colon (p ≤ 0.05), probably due to the incre in nutrient absorption, which is mainly attributable to the dietary fibers tha able after the pretreatment with white-rot fungi and their lignocellulolytic plexes [36,38]. Thus, supplementing growing rabbit diets with sorghum al SSF with T. maxima CU1 and P. sanguineus CS2 might contribute to incre transit time, improve mucosal functionality, and modulate their microbiot vestigations will be performed to explore these issues.…”

Effect of Replacing Berseem Hay by Dried Sugar Beet Tops on Performance of Friesian Calves

“…These results are in accordance with those obtained by Ali and El-Saidy (2003) concluded that DSBT could be used successfully as a replacer to 50% from BH in ration of growing lambs without any detritus effects on productive performance. Abo El-Maaty et al (2017 and2018) found that the digestibility coefficients of dry matter (DM), crude protein (CP), ether extract (EE) and NFE of 12-week old NZW rabbits were improved by feeding diets containing SBT. Bendary et al (2000) reported that no significant differences among experimental ration in digestibility coefficient of all nutrients when cow fed rations containing different forms of sugar beet tops and berseem silage compared with those fed dry summer ration.…”
