the objective of this study was to evaluate the effect of dietary supplements with lead acetate and aluminosilicates (atn) on antioxidative enzyme activities and lipid peroxidation of the heart and skeletal muscle tissues of broiler chickens. broilers were allotted to four diets including the control group, the pb group, the aluminosilicate-atn (antitoxic nutrient) group and the pb+atn group, i...

The weaning time is a crucial period in the management of piglets. The risk of development of post-weaning diarrhoea (PWD) in piglets is high. PWD is the cause of serious economic losses in pig herds. Since 2006, the use of antibiotic growth promoters for prevention of diarrhoeal diseases in piglets has been banned. This measure also led to the investigation of alternative suitable feed supplem...

The aim of the present studies was to evaluate the effects of salinomycin (Biocox®) on the piglet and growing-fattening pig performance. Forty-eight piglets and 40 growing pigs were used. Biocox® was included in the piglet feed at a level of 60 ppm and the observation period lasted for 35 days. In the feed for growing pigs Biocox® was included at 60 ppm during the first 14 days and at 30 ppm th...

Liquid feed supplements (LFS) have a long history of use in dairy cattle feeding. Initially, LFS were used in lick tanks as a source of non-protein nitrogen (NPN) and energy for dry cows and replacement heifers. More recently, with the increased popularity of feeding total mixed rations (TMR), LFS have been marketed with the following claims: • safe and uniform delivery vehicle for micro-nutrie...
