“…We expected that the higher water content would also coincide with a higher protein content, based on the close relationship between nitrogen deposition and water retention (Geay and Robelin, 1979). The unaltered protein content in the LT muscle was not in accordance with other experiments (Fiems et al, 1993;Boucque, Fiems, Moermans, Cottyn and Sommer, 1994).…”

Forty-eight culled dairy cows were assigned to one of two treatment groups to investigate the effect of a |3-adrenergic agonist in mature cattle. They were finished during a 63-day period on a concentrate diet, containing 0 or 4 mg/kg cimaterol. No food was given in the 20 h prior to slaughter. Cimaterol had no effect on food intake, but significantly improved food conversion efficiency and increased liveweight gain, carcass weight and dressing proportion (P < 0-05). Cimaterol induced muscle hypertrophy as evidenced by an improved EUROP carcass classification and a higher longissimus thoracis (LT) cross-sectional area (P < 0-001). EUROP fat score and fat content in the carcass and the LT were lowered (P < 0-05). Cimaterol resulted in brighter meat (higher L*'-value: 37-0 v. 35-6; P<0-05) with a higher shear force value (64-0 v. 46-4 Newton; P<0-01) compared with control animals. It seems likely that mature cattle receiving cimaterol respond similarly to younger growing animals.

“…Similarly, Strydom (2009) found greater drip loss ( > 1.79%) in ZH-fed steaks than control steaks; however, RH and clenbuterol groups had intermediate drip loss. In contrast, other studies have indicated no or little variation in drip loss using cimaterol (Fiems et al, 1990;Boucqué et al, 1994).…”

An experiment was conducted to determine the effects of zilpaterol hydrochloride mM supplementation (ZH; 8.3 mg/kg on a DM basis for 20 d) and calcium chloride injection [CaCl(2), 200 at 5% (wt/wt) at 72 h postmortem] on palatability traits of beef (Bos taurus) strip loin steaks. Select (USDA) strip loins were obtained from control (no ZH = 19) and ZH-supplemented carcasses (n = 20). Right and left sides were selected alternatively to serve as a control (no INJ) or CaCl(2)-injected (INJ) and stored at 4°C. Before injecting the subprimals (72 h postmortem), 2 steaks were cut for proximate, sarcomere length, and myofibrillar fragmentation index (MFI) analyses. At 7 d postmortem each strip loin was portioned into steaks, vacuum packaged, and aged for the appropriate period for Warner-Bratzler shear force (WBSF; 7, 14, 21, and 28 d postmortem), trained sensory analysis (14 and 21 d postmortem), purge loss (7 d), and MFI (3, 7, 14, 21, and 28 d postmortem). Results indicated steaks from both ZH supplementation and INJ had reduced WBSF values as days of postmortem aging increased. The WBSF values of ZH steaks were greater (P < 0.05) than no ZH steaks at each postmortem aging period. The INJ steaks had lower WBSF values (P < 0.05) than non-injected steaks. A greater percentage (91 vs. 71%) of steaks had WBSF values < 4.6 kg from steers with no ZH supplementation at 7 d postmortem, but the percentage did not differ (P > 0.05) due to ZH at 14, 21, or 28 d or due to INJ at any aging period. Trained panelists rated tenderness less in ZH steaks than steaks with no ZH at 14 d and 21 d. However, INJ improved (P < 0.05) the tenderness ratings and flavor intensity of the trained panelists, compared with their non-injected cohorts at 21 d. Zilpaterol hydrochloride supplementation reduced (P < 0.05) MFI values, but INJ resulted in greater (P < 0.05) MFI values compared with no INJ. Subprimals from ZH and INJ showed greater purge loss (P < 0.05). Although no interactions were found with ZH and CaCl(2), injecting USDA Select strip loins from ZH-fed cattle can help reduce the normal WBSF variation as it does in steaks from non-ZH-fed cattle.

“…Evidence of other βAA repartitioning capacity in cattle is well documented. An increase in carcass protein and moisture with a decrease in carcass fat percentage has been shown with clenbuterol (Ricks et al, 1984), cimaterol (Boucqué et al, 1994;Fiems et al, 1995;Dawson et al, 1997), and ractopamine (Parrott et al, 1990;Schroeder et al, 2003b,c). Additionally, Moloney et al (1990) showed an increase in lean and a decrease in fat due to treatment with the βAA L 644,969 .…”

“…As with any repartitioning agent, there is a concern of treatment effects on meat shear force and palatability. Other βAA such as clenbuterol, L-644,969 , and cimaterol have been shown to have negative effects on beef shear force (Miller et al, 1988;Boucqué et al, 1994;Moloney et al, 1994). Even the β 1 -agonist ractopamine hydrochloride has been shown to increase beef LM Warner-Bratzler shear force and decrease sensory tenderness scores when supplemented at approximately 300 mg/animal per day (Schroeder et al, 2003a).…”

Experiments were conducted at 3 US locations (California, Idaho, and Texas) to determine the effects of dietary zilpaterol hydrochloride and duration of zilpaterol feeding on carcass composition and beef palatability. At each site, 160 steers and 160 heifers were stratified within sex by initial BW (study d -1) and assigned randomly 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. When included in the diet, zilpaterol was supplemented at 8.3 mg/kg (DM basis). Each pen consisted of 10 animals. After slaughter 2 carcasses per pen (n=64 per trial site) were selected. The entire right side of the selected carcasses was collected for dissection and chemical analysis of the soft tissue. Additionally, the left strip loin was collected for Warner-Bratzler shear force determinations and aged to 28 d postmortem. Sensory analysis was conducted on the Idaho trial site samples only. All data were pooled for analyses. Feeding zilpaterol hydrochloride increased carcass muscle deposition (P<0.01) of both steer and heifer carcasses. However, carcass percentage fat of steers and heifers was not affected (P>0.11) by the zilpaterol treatment. In heifer carcasses, carcass moisture percentage was increased (P=0.04) and bone percentage was decreased (P=0.02), whereas in steer carcasses, carcass moisture and bone percentage were not affected (P>0.10). In heifer carcasses, carcass ash percentage was not affected (P=0.61) by zilpaterol, whereas in steer carcasses, carcass ash percentage tended (P=0.07) to be increased. The protein-to-bone ratio was increased (P<0.001) by zilpaterol hydrochloride treatment in both steers and heifers, whereas the protein-to-fat ratio was not affected (P=0.10). Cooking loss of the LM was not affected (P=0.41) by zilpaterol treatment of steers or heifers. However, LM Warner-Bratzler shear force was increased (P=0.003) on average (3.3 vs. 4.0 kg) due to zilpaterol hydrochloride treatment of both steers and heifers. In both steers and heifers, LM sensory panel scores of overall juiciness (6.2 vs. 6.0), tenderness (6.2 vs. 6.0), and flavor intensity (6.2 vs. 6.0) tended (P=0.06) to be decreased in cattle supplemented with zilpaterol. Zilpaterol hydrochloride is a repartitioning agent that seems to affect carcass composition primarily through protein deposition. However, zilpaterol treatment can adversely affect tenderness and other palatability traits.
