Effect of Monensin, Estradiol Controlled Release Implants and Supplement on Performance in Grazing Steers

Five trials in five locations in the United States involving 512 steers were conducted to evaluate the effect of monensin [200 mg/d in .9 kg of supplement (Rumensin)] and estradiol- controlled release implants (Compudose) administered alone and in combination on average daily gain (ADG) in steers on pasture. The effect of energy supplementation on rate of gain was also evaluated in these same trials. The initial weight of steers averaged 250 kg and the average duration of the five trials was 124 d. Estradiol-controlled release implants increased ADG by 15.6% (.095 kg/d; P\u3c.0001) and monensin increased ADG by 8.1% (.054 kg/d; P\u3c.05). The combination of estradiol-controlled release implant and monensin increased ADG by 27.4% (.I68 kg/d). Treatment responses were additive relative to ADG response, with no interaction observed between the treatments. Nine-tenths kilogram of an energy supplement/d increased ADG by 12.4% (.073 kg/d; P\u3c.Ol)

GNU Radio

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available, low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems
