Modification of beef quality through steer age at slaughter, breed cross and growth promotants
Download2012
Aalhus, J. L., Basarab, J. A., Girard, I., Bruce., H. L., Larsen, I. L.
A 23 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth implants use (Component E-S, TE-S), ractopamine hydrochloride (RAC) feed supplementation use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on pH, temperature, objective...

A 24 factorial experiment tested the interactions of slaughter age (12–13 or 18–20 mo), growth hormone use, β-adrenergic agonist (β-AA) use and breed cross [Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA)] on the composition, fibre types, and connective tissue characteristics of m....

Modification of steer muscle composition and meat quality through age at slaughter, hormonal implants, ractopamine hydrochloride feed supplementation, and breed crosses
DownloadFall 2010
Management systems that enhance carcass yield can increase the efficiency and competitiveness of beef producers, but meat quality should not be negatively affected. Continental or British crossbred steers were finished to either 12 to 13 or 18 to 20 months of age and were either untreated or...

Trained panel sensory evaluation of m. longissimus thoracis, m. gluteus medius and m. semimembranosus from Angus crossbred steers: the influence of hormonal growth promotants, ractopamine hydrochloride, and selection for high or low residual feed intake.
DownloadFall 2019
Selection of cattle for residual feed intake (RFI) does not affect rate of weight gain; rather, low RFI cattle consume less feed than high RFI animals to attain a similar final body weight and are thus considered feed efficient. Reducing production costs by selecting low RFI cattle and...
