Ralgro-implanted bulls: Performance, carcass characteristics, longissimus palatability and carcass electrical stimulation

摘要: Summary Twenty of 40 Angus bulls were implanted (I) five times with 36 mg Ralgro| at average intervals 106 d, beginning near birth. All and their dams on bluestem pasture initially and, an age 320 d fed a concentrate diet until they slaughtered, weighing either 454 or 499 kg. One side each carcass was electrically stimulated. Average daily gain feed efficiency I improved 6.5 to 10.4% 7.9 8.1%, respectively, depending upon the end point comparison nonimplanted (NI) bulls. Implanted attained slaughter weights 42 sooner than did NI Implantation decreased (P .05) seminal vesicle pituitary weights. Carcasses from had more by implantation. Taste panel flavor intensity detectable connective tissue scores higher (P<.05) for steaks Longissimus steak tenderness evaluations both groups light-weight
