Effects of Antioxidants on Growth and Total Antioxidant Capacity of Neonate Calves

Abstract

Micronutrients support immune functions and are essential for optimized health and production of animals. This study was conducted to evaluate the effect of vitamin E and vitamin C, alone or in combinations, on growth and antioxidant capacity of neonate dairy calves. For this purpose, eighteen female Holstein Friesian calves were selected. Experimental treatments were; T0 or control (milk without vitamin supplementation), T1 (milk supplemented with 250mg of vitamin E), T2 (milk supplemented with 500mg of vitamin E), T3 (milk supplemented with 1000mg of vitamin C), T4 (milk supplemented with 250mg of vitamin E and 1000mg of vitamin C) and T5 (milk supplemented with 500mg of vitamin E and 1000mg of vitamin C). Experimental treatments were started from the third day till 60th days of calf’s life. Blood was collected in clot-activator tubes for TAC at day 01, 30 and 60. Body measurements were noted during 1st, 3rd, 6th and 9th week of this trial. Results showed that the TAC was significantly high in T1 group during first month. At the end of the trial (day 60), TAC were highest in T0 and T1comparetively. The wither height, heart girth and body length were significant in supplemented groups compared to control. In conclusion, it is asserted that the supplementation of vitamin E and vitamin C have beneficial effect on growth and antioxidant capacity of neonate calves.
