Rabbit Diets on Growth Performance, Carcass Characteristics, Serum Biochemistry
and Liver Oxidative Status]]>AshourE.A. AlagawanyM. RedaF.M. Abd El-HackM.E. 112014911This study was performed to investigate the effect of dietary supplementation
with Yucca schidigera Extract (YE) as growth promoter and natural antioxidant
on performance, carcass characteristics, serum metabolites and liver oxidative
status in growing rabbits. A total of 80, New Zealand White (NZW) rabbits at
5 weeks of age were randomly assigned to four treatments with four replicates.
The dietary treatments consisted of the basal diet as control, YE groups receiving
200, 400 and 600 g kg-1 YE added to the basal diet. Body weights
of rabbits were measured at 5, 7, 9 and 13 weeks, feed intake was measured at
the same periods and feed conversion was calculated, accordingly. At weeks13,
carcass characteristics, blood profile and antioxidant status in liver were
determined. Live Body Weight (LBW) and Body Weight Gain (BWG) were not significantly
influenced by the dietary treatments. Giblets percentage and relative weights
(organ weight, g/100 g of body weight) of the heart, liver, spleen and lungs
of rabbits at 13 weeks were not affected by dietary treatments. However, carcass
yield percentage and relative organs of kidneys, skin and legs were statistically
(p<0.05) influenced by dietary treatments. There were no differences (p<0.05)
in total protein, globulin, AST, ALT and LDL-cholesterol due to treatments.
While, the other blood parameters were statistically affected by YE supplementation.
Dietary supplementation of YE to basal diet exhibited a significantly positive
effect on immune related parameters (albumin, ALB immunoglobulin, IgG and IgM)
and serum ammonia. The lowest value of ammonia achieved by animals fed diet
contained YE 200 mg kg-1 diet. Rabbits fed YE 400 and 600 mg kg-1
of diet produced the best results of total-cholesterol in blood versus other
diets, also HDL-cholesterol was gradually decreased with increasing YE supplementation.
Hepatic Superoxide Dismutase (SOD) activity and reduced Glutathione (GSH), Malondialdehyde
(MDA) concentrations were not significantly affected by the different levels
of YE. But lipid peroxidation was slightly decreased with increasing YE supplementation.
Dietary supplementation of YE to control diet exhibited a significantly positive
effect on Glutathione Peroxidase (GSH-Px) and Catalase (CAT) activities. It
could be conducted that, rabbits fed diet supplemented with YE did not affect
growth performance in general but improved the immunity responses, in addition,
animals fed diet supplemented with phytogenic additive had lower ammonia in
blood, MDA in liver and increased hepatic antioxidant activities.]]>Abaza, I.M. and H.
