Serum antioxidants and trace minerals as influenced by vitamins, probiotics and proteins in broiler breeders

Abstract

One hundred and eighty birds at the age of 65 weeks were induced to moult by mixing zinc oxide in their feed at the rate 3000 mg/kg of feed. Upon completion of moulting, the birds were divided into six groups (five replicates) by a completely randomised design. One group was kept as control (16% crude protein [CP]) while the other five were supplemented with vitamin E (100 IU/kg feed), vitamin C (500 IU/kg feed), probiotics (50 mg/L), protein level (14% CP) and their combination. At the end of the experiment, the results revealed that serum total antioxidant response significantly increased in the vitamin E fed group compared to the other treated groups. Paraoxonase and arylesterase were significantly higher in vitamin E and C groups. The ceruloplasmin level decreased significantly in the vitamin C fed group as well as in the group having the combination of all the treatments. The homocysteine was significantly lower in the vitamin E fed group compared to the other treated groups. In trace elements, serum zinc was significantly high in vitamin E supplemented group. These findings suggested that compared to other treatments, vitamin E has pronounced influence on improving the anti-oxidant status in male broiler breeders.

“…On the other hand, Cu and Mn decreased significantly, while Zn concentration was increased in the treated group. Increased blood concentration and reduced Mg levels were reported in broiler breeders by a mixture of the probiotics (Khan, Zia‐ur‐Rahman, Javed, & Muhammad, ; Khan et al., ). Studies are scarce on the effect of probiotics on blood minerals in animals.…”

Effect of different levels of alpha tocopherol on performance traits, serum antioxidant enzymes, and trace elements in Japanese quail ( Coturnix coturnix japonica ) under low ambient temperature

“…Sahin et al (2002) concluded that vitamin E supplementation at various levels (125, 250, and 500 mg/kg) increased significantly the Zn concentration in the egg yolk in laying Japanese quail. Environmental stress has been found to reduce the concentration of certain vitamins and minerals (Khan et al, 2014a(Khan et al, , 2014b. Majid et al (2015) suggested that vitamin E increases the capability of the body to retain Zn by decreasing its excretion from the body.…”

“…In the present study, we found that Zn concentration increased significantly in the quails supplemented with vitamin E at the level of 150 mg/kg. Sahin et al (2003b) and Khan et al (2014b) reported that vitamin E supplementation increased serum concentration of Zn in birds subjected to various kinds of stresses. Sahin et al (2002) concluded that vitamin E supplementation at various levels (125, 250, and 500 mg/kg) increased significantly the Zn concentration in the egg yolk in laying Japanese quail.…”
