The developing immune system is particularly sensitive to environmental and hormonal influences. Genders can differ in this sensitivity as well. Because the heavy metal, lead, can suppress Th-1 associated function among perinatal thymocytes and cause a systemic loss of postnatal Th-1 function, we investigated the ability of in ovo administered lead and testosterone to alter thymocyte maturation...
Effect of Different Feed Additives on Growth Performance and Blood Profiles of Korean Hanwoo Calves*
This experiment was conducted on 60 Hanwoo calves comprising five feed additive groups, with 12 calves in each group, to determine the effects of additives at preand post-weaning on growth performance and blood profile. The groups were control, antibiotic (Neomycin 110 ppm), illite (2%), fermented green tea probiotics (FGTP, 0.5%), and mixed additives (FGTP 0.25%, illite 1% and licorice 0.1%). ...
Many studies tested different feed additives, among these additives, humic substances (HS) have been used in livestock and poultry diets. Humic substances commonly present in nature as they are created from the organic matter decomposition, and are normally found in the soil and natural water. Active components of HS consist of humic acid (HA), humus, ulmic acid, fulvic acid, humin and certain ...
Essential trace elements (TEs) are major nutritional feed additives, required for the health and welfare of farm animals, especially under intensive husbandry conditions. Within the European Food Safety Authority (EFSA), risk assessment of feed additives is carried out by the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP), which is increasingly confronted with additi...
The aim of our present study was to examine the regulation of xenobiotic- and antioxidant enzymes by phytogenic feed additives in the intestine and the liver of broilers. A total of 240 male Ross-308 broiler chickens (1 d old) were fed a commercial starter diet for 2 weeks. On day 15, the birds were assigned to six treatment groups of forty birds each. The control (Con) group was fed a diet wit...
