Effects of the phenethanolamine clenbuterol on protein and lipid metabolism in growing rats

Abstract: Zusammenfassung Einfluß des Phenylethanolamins Clenbuterol auf den Protein‐ und Fettstoffwechsel wachsender Ratten Es wurden Untersuchungen an weiblichen Wistar‐Ratten von unterschiedlicher Lebendmasse mit der Referenzsubstanz Clenbuterol durchgeführt, um die ernährungsphysiologische Attraktivität der β‐Agonisten zu beurteilen und um Erkenntnisse über ihren Wirkmechanismus zu gewinnen. Die stimulierenden Effekte von Clenbuterol (25 ppm in der Diät) auf den Zuwachs und die N‐Retention stiegen mit der Lebendmass… Show more

“…However, knowledge about the mode(s) of growth promotion by antimicrobial agents in animals remains insufficient. Greife et al suggested that bacteria resident in the rumen and intestines are affected by antibiotics and that the symbiotic relationship between bacteria and animal is modified [10]. Furthermore, they reported that antibacterial agents, used as growth promoters, are able to reduce the intestinal microflora, which competes with the host for nutrients in the intestinal lumen.…”

“…Although research has not determined how duration of β-agonist supplementation may influence composition of gain, initial weight may play a role in the response. Previous research has demonstrated that the response to β-agonists can be influenced by initial weight, as rats administered clenbuterol (Greife et al, 1989) and bulls supplemented with cimaterol (Vestergaard et al, 1994), had increased gain in response to β-agonists when Table 6.

“…However, small amounts of β 2 -AR mRNA were present in total RNA from these cultures ( Bridge et al, 1998 ). Studies feeding clenbuterol to both young and old rats suggested that older, more mature rats were more responsive to clenbuterol administration compared to younger rats ( Greife et al, 1989 ). Clenbuterol feeding for 14 d to older, heavier (185 g) rats increased growth rate 11% compared to only a 22% increase in lighter (100 g), younger rats ( Greife et al, 1989 ).…”

Clenbuterol feeding for 14 d to older, heavier (185 g) rats increased growth rate 11% compared to only a 22% increase in lighter (100 g), younger rats ( Greife et al, 1989 ). The authors speculated that the disparate response was related to relative differences in body fat content.…”
