Abstract
Effects of active immunization against the recombinant second extracellular loop of sheep β<sub>2</sub>-adrenoceptor on growth and blood biochemical parameters of female rats
Highlights
Leaner carcass production in the husbandry has been emphasized because of the declining demand for animal fat and the increasing demand for lean meat. β-adrenoceptors (β-ARs) are involved in adipose tissue lipolysis and protein deposition in human and animal modulated by β-agonists (Langin, 2006)
We investigated effects of active immunization with the recombinant fusion protein on feed intake and growth of rats
Growth performance and feed intake of rats were not affected by active immunization with recombinant fusion protein (rBAR) (Table 2)
Summary
Leaner carcass production in the husbandry has been emphasized because of the declining demand for animal fat and the increasing demand for lean meat. β-adrenoceptors (β-ARs) are involved in adipose tissue lipolysis and protein deposition in human and animal modulated by β-agonists (Langin, 2006). Leaner carcass production in the husbandry has been emphasized because of the declining demand for animal fat and the increasing demand for lean meat. Β-adrenoceptors (β-ARs) are involved in adipose tissue lipolysis and protein deposition in human and animal modulated by β-agonists (Langin, 2006). Carcass composition and feed efficiency of domestic animals can be improved by using β-agonists, such as clenbuterol, ractopamine and zilpaterol (Scramlin et al, 2010). Detrimental effects of these compounds are obviously. They are generally heat-stable and orally active, and have the potential to affect human’s health if consumed accidentally (Mersmann, 1998). Β-agonists are forbidden to use in livestock production in many countries. It is necessary to focus research efforts on developing new and safe ways to manipulate animal growth
