Abstract
This study aimed to investigate the impact of dietary vitamin E (DL-α-tocopherol acetate) on growth
performance, amount of malondialdehyde in serum, serum vitamin E level, haematological and
biochemical metabolites of Mahali goat kids. Twenty four male kids weighing 10-15 kg were randomly
allocated to one of four groups to receive four different treatments of vitamin E. Group one (control,
C), 2nd group received 300IU vitamin E (300 E), 3rd group received 500IU vitamin E (500 E), and
1000IU vitamin E (1000 E) in the 4th group. The animals were housed in separated pens and fed
concentrate with a barley hay diet. Blood samples were weekly collected through the jugular vein for
haematological and biochemical analysis. The evaluation of malondialdehyde and vitamin E content
in serum was performed. The result revealed that vitamin E significantly increased red blood cells
(RBC), Haemoglobin (HB), white blood cells (WBC), and differential white blood cells. Vitamin E
significantly (p < 0.001) increased level of vitamin E in serum, while, reduced total protein (TP),
albumin, alanine transaminase (ALT), aspartate transaminase (AST), high density lipoproteins (HDL),
cholesterol, and malondialdehyde (MDA) in the serum. In conclusion, dietary supplementation of
vitamin E may effectively improved haematological, biochemical parameters, serum α-tocopherol
content as well as malondialdehyde of Mahali goat kids.
