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...

background: recombinant monoclonal antibodies have been marketed in last three decades as the major therapeutic proteins against different cancers. however choosing a proper medium and supplements to reach the high expression is a challenging step. despite of commercial serum free and chemically defined media, there are still numerous researches seeking the optimum media to gain higher expressi...

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...

The recycling of rendered animal products back into the feed of ruminant livestock species has had a positive impact both on the efficiency of livestock production and the availability of meat and milk for consumers at an affordable price. Rendered animal products are distinguished by a high protein content containing amino acids that resist microbial degradation in the rumen, and for extracted...
