Payout characteristics of anabolic agents from Synovex®, Finaplix®, and Revalor® implants in finishing yearling steers

Evaluation of Synovex Plus, Synovex S and Revalor S Implants in Feedlot Steers

One hundred forty-four crossbred yearling steers with an average weight of 841 pounds were used in a 116day experiment. Steers received either 1) no implant, 2) Synovex S ̈, 3) Revalor S ̈, or 4) Synovex Plus ̈. All implanted groups consumed more feed and gained faster and more efficiently than non-implanted steers. There were no significant differences in gain, feed intake or feed efficiency amon...

Evaluation of Synovex Choice Versus Revalor Implant Strategies in Beef Finishing Steers

Evaluation of Revalor-IH and Revalor-IS as Initial Implants Compared with Traditional Initial Implants for Finishing Heifers and Steers

Two commercial feedlot experiments were conducted to compare performance and carcass characteristics of feedlot heifers and steers using 2 implant strategies. In Exp. 1, heifers (n = 1,124; initial BW = 279 ± 5 kg) were administered either Revalor-IH [Intervet/ Schering Plough Animal Health, DeSoto, KS; 8 mg of estradiol (E2) and 80 mg of trenbolone acetate (TA)] or Synovex-H (Fort Dodge Animal...

Effects of Final Implant Type and Supplementation of Melengestrol Acetate® on Finishing Feedlot Heifer Performance, Carcass Characteristics, and Feeding Economics1

Three finishing experiments were conducted in commercial feedlots to determine effects of implant programs on finishing heifer performance, carcass characteristics, and economics. A total of 3,307 heifers were used in the three experiments. Overall, four treatment comparisons were tested within the three separate experiments. Treatment groups included the following: 1) heifers implanted with Sy...

Relationship of anabolic status and phase and rate of growth to priorities for protein and fat deposition in steers.

The effects of anabolic implants, growth phase (growing vs finishing) and rate of growth on the priorities for protein and fat deposition were determined in yearling cattle. Santa Gertrudis crossbred yearling steers weighing 290 kg were individually fed diets varying in forage and grain content and either not implanted (n = 16) or implanted (90-d intervals) with Ralgro (n = 13) or Synovex-S (n ...
