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.
