Changes of Serum Vitamin A, Vitamin E, Selenium, Lipid Compositions and Blood Glutathioneperoxidase Activity during the Growth Stage of Holstein Bull Calves and Heifer Calves

Antioxidant enzyme activity in the muscles of calves depleted of vitamin E or selenium or both.

Feeding diets depleted of vitamin E and Se to cattle can induce a disease known as nutritional degenerative myopathy. It is believed that an increased peroxidative challenge in muscle is involved in the pathogenesis of this disease. A number of species can up-regulate the activity of some antioxidant enzymes, including glutathione reductase (EC 1.6.4.2), glutathione transferase (EC 2.5.1.18), g...

Effect of Parenteral Administration of Vitamin A in Dairy Cattle During Dry Period, on Vitamin A Status of Neonatal Calves

The present study has been conducted to evaluate the effect of intramuscular administration of vitamin A during dry period in pregnant dairy cows which have already received it in their daily ration on vitamin A status of neonatal calves.Single intramuscular injection of 2000000 IU vitamin A was carried in 10 dairy cows at 7 months of pregnancy (group 1) and in another 10 dairy cows at 8 months...

Hemato-biochemical and Cortisol Profile of Holstein Growing-calves Supplemented with Vitamin C during Summer Season

Effect of vitamin C (VC) on biochemical, hematological and cortisol profile of growing Holstein calves during summer was investigated. Eighteen calves between 14 and 16 weeks of age were divided equally into two groups. One group received a diet supplemented with VC (20 g/d) for 60 days, while other non-supplemented diet fed group served as a control (CON). The temperature humidity index (THI) ...
