The ocular history was significant for uneventful cataract surgery approximately 3 years earlier. Pseudophakic bullous keratopathy was diagnosed and Descemet-stripping automated endothelial keratoplasty (DSAEK) performed. During surgery, a retained nuclear fragment was discovered in the anterior chamber. The fragment was removed and the DSAEK completed successfully. At the 4-month follow-up, the symptoms had completely resolved and the uncorrected distance visual acuity in the affected eye was 20/40.”
“Experiments were conducted at 3 US locations (CA, ID, and TX) to determine the effects of dietary zilpaterol hydrochloride (Zilmax, Intervet Inc., Millsboro, DE)

and duration of zilpaterol feeding on performance and carcass merit of finishing steers and heifers. At each site, 160 steers and 160 heifers were stratified within sex by initial BW (study see more d – 1) and assigned randomly Selleck PLX3397 within BW strata to 1 of 4 treatments in a randomized complete block design (4 blocks/treatment for each sex). The 4 treatments were arranged in a 2 (no zilpaterol vs. zilpaterol) x 2 (20 or 40 d duration of zilpaterol feeding) factorial arrangement of treatments. When included

in the diet, zilpaterol was supplemented at 8.3 mg/kg of DM. Each pen consisted of 10 animals. Each animal was individually weighed unshrunk on d 1, 21 or 41, and 66 of the experiment. Following d 66, cattle were slaughtered and carcass data collected. Feeding zilpaterol increased (P < 0.01) final BW of steers and heifers by 11.6 and 6.7 kg, respectively. In addition, feeding zilpaterol hydrochloride increased (P = 0.001) ADG 36 and 18%, and increased (P < 0.001) G: F 28 and 21% for steers and heifers, respectively.

For heifers, DMI was selleck compound decreased (P < 0.001) 6.2% when zilpaterol was fed, whereas in steers DMI tended (P = 0.09) to be decreased 2%. For steers and heifers, feeding zilpaterol increased (P < 0.001) HCW 16.4 and 12.1 kg, dressing percentage 1.5 percentage units for each sex, and LM area 8.23 and 6.37 cm(2), respectively. Twelfth-rib fat (P >= 0.12) and KPH (P >= 0.70) were not affected by feeding zilpaterol to steers or heifers. Feeding zilpaterol decreased (i.e., improved; P = 0.02) calculated yield grade of steer and heifer carcasses. Marbling score (P = 0.002) and quality grade (P = 0.002) were decreased when zilpaterol hydrochloride was fed to steers, and the decrease in marbling score and quality grade tended to be greater when zilpaterol was fed for 40 compared with 20 d (zilpaterol x duration interaction, P = 0.07). For heifers, marbling score tended (P = 0.07) to be decreased and quality grade was decreased (P = 0.05) when zilpaterol hydrochloride was fed. In general, it appears from these data that zilpaterol hydrochloride fed for 20 to 40 d at the end of the finishing period enhances growth performance and carcass muscle deposition for steers and heifers.
