Abstract |
In order to evaluate the nutritional value of cereal grains (CG) used in
rabbits feed, an in vivo
digestibility and metabolism test were conducted over five days on forty
adult rabbits with an average weight of 1921.65±5 g. An experimental
fisher block with five treatments and eight replicates of rabbits was
used. Rabbits were fed with each single CG: White Maize EVDT-W (WM),
Yellow Maize SAMAZ-40 (YM), White Sorghum (WS), Red Sorghum (RS) and
Millet (MI). The composition of CG was determined through chemical
analyzes. The apparent digestibility of Dry Matter (DM), Organic Matter
(OM), Ether Extract (EE), Crude Fiber (CF), Neutral Detergent Fiber
(NDF), Acid Detergent Fiber (ADF) and Ash were evaluated. Similarly,
concentrations of Glucose, Total Proteins, Total Cholesterol and
Triglycerides were determined in rabbits blood through biochemical
analyzes. The results showed that rabbits similarly digested (P> 0.05)
DM (85 to 93%), OM (86 to 93% DM), EE (97 to 99% DM), NDF (93 to 96% DM)
and ADF (47 to 61% DM) of the five CG. However, apparent digestibility
of CF and Ash of the five CG was low (36 to 57% DM and 25 to 64% DM,
respectively). Millet grains appeared to be the grain that nutritive
compound were more digestible by rabbits. Moreover, CG had no
significant influence (P>0.05) on blood glucose, Total Protein, Total
Cholesterol, and Triglycerides levels in rabbits. However, in all the
dietary treated, blood total protein of rabbits increased significantly
(P<0.05) after feeding with the cereal grains. The good digestive use of
cereal grains nutrients indicates that all the tested grains are
suitable in rabbit’s balanced feed.
