Abstract Historic data supports the use of pre-weaning implants to maximize beef calf weaning weight, but their use has declined over the recent decade. A total of 96 beef steers (initially 85.2 kg BW and > 45 d of age) were used in a 168-d study to evaluate the effects of Synovex C® implantation during suckling on pre-weaning calf growth performance. At initial processing, calves were individually weighed and allotted in a completely randomized design to one of two treatments: 1) not implanted (control) or 2) implanted with 150 mg of trenbolone acetate and 21 mg of estradiol benzoate (SYNOVEX® ONE GRASS, Zoetis, Kalamazoo, MI). All calves were weighed on d 0 (implantation), 83, 126 and 168 (weaning), with ADG calculated for each period. Data were analyzed using the GLIMMIX procedure of SAS (v9.4, Cary, NC). There were 48 replicates per treatment, with grazing location as a random effect. While there were no detected differences in BW during the initial phases (P > 0.10), implanted calves tended to have greater (P = 0.100) greater weaning weight than non-implanted calves (279 vs. 265 kg, respectively). Calves implanted with SYNOVEX® ONE GRASS had 0.8, 0.12, and 0.16 kg/d greater (P < 0.05) ADG than those that were not implanted in all three phases. This resulted in an average of 0.10 kg/d greater (P = 0.002) ADG in implanted calves overall compared to the control. In conclusion, this research showed significant increases in suckling calf ADG in implanted calves compared to their non-implanted counterparts, which led to a tendency for 14-kg greater weaning weights. Additional research is warranted to consider the post-weaning growth and impact of re-implanting, but this data reinforces previous literature that suckling calf implantation continues to be cost effective for cow-calf producers.

Tenderness has a prominent position on meat quality and is considered to be the sensory characteristic that most influences meat acceptance. Therefore, the aim of this study was to evaluate the accuracy and determine correlations among three different meat shear force techniques. Commercial samples of bovine Longissimus thoracis et lumborum (BLTL), Tensor fasciae latae (BTFL), Semitendinosus (BST), Psoas major (BPM), Biceps femoris (BBF) and swine Longissimus thoracis et lumborum (PLTL) were analyzed for pH, proximate composition, cooking loss and shear force with a classical Warner-Bratzler device and a TA-XT2 Texturometer equipped with shear blades 1 and 3 mm thick. The effect of different techniques in each studied muscle was statistically analyzed and regression curves were built. Results from the 1 mm blade were quite similar to the ones obtained with the Warner-Bratzler, however the results from 3 mm blade were overestimated (p<0.05). Significant correlation (p<0.01) among shear force technique using Warner-Bratzler and the ones using the Texturometer was observed (0.47 for 1 mm blade and 0.57 for the 3 mm blade). In conclusion, we found that the 1 mm blade and the Warner-Bratzler machine are reproducible for all tested muscles, while the 3 mm blade is not reproducible for the BTFL, BST, BPM, BBF, PLTL. There is a significant correlation between the results obtained by the classical Warner-Bratzler and the TA-XT2 Texturometer equipped with both blades. Therefore, TA-XT2 Texturometer equipped with the 1mm blade can perfectly replace the traditional Warner-Bratzler device.
