Abstract
Eighteen male Friesian calves averaging 275 kg body weight were used to
study the effect of feeding rations containing two different levels of poultry litter and
corn silage on digestibility. nutritive values. animal performance and minerals status.
Calves were divided into three similar groups assigned randomly to feed on three
experimental rations as follows:
R1 (control): 65 % concentrate feed mixture + 15 % berseem hay 3 third cut +
20 % rice straw. R2: 12.5 % poultry litter + 12.5 % corn grain + 75 % corn silage R3:
25 % pouitry litter + 25 % corn grain + 50 % corn silage.
The results showed that digestibility coefficients. nutritive value . pH and
ammonia-N were higher in R2 and R3 compared with the control group , mean while
the TVFA's was lower in R2 and R3 comported with the control group.Live body gain
and feed efficiency recorded higher value in R2 than R3 and the control group.
Minerals content of poultry litter was higher compared with the other ingrediens
feedstuffs. Minerals contents ofthe experimental rations increased with increasing the
level of poultry litter. Minerals intake. absorption and retention increased significantly
(P<0.05) with increasing the level of poultry litter. The efficiency of minerals absorption
and retention significantly decreased (P<0.05) with increasing dietary minerals intake.
Minerals concentrations in blood and seminal plasma. liver. kidneys, testis and
muscles of Friesian calves increased significantly (P<0.05) with increasing the level of
poultry litter and decreasing the level of corn sitage in the rations. The concentrations
of minerals in blood and seminal plasma. liver. kidneys. testis and muscle of Friesian
calves fed R3 {contained 25% poultry litter) were higher than the normal levels.
It could be concluded that using 125% from poultry litter with 50% corn silage
in feeding of Frisian calves appeared to give better results of daily gain and more
efficient to get feed efficiency as well as to cover the mineral efficiency.
