“…These results are consistent with those of studies that evaluated two β-AA on finishing lambs where not significant effects were observed on pH, hold water capacity and water loss (Brand et al, 2013;López et al, 2010). However, present results contrast partially with those of Dávila et al, (2013) that showed pH values of 6.2 in hair lamb treated with ZH, which is a value that would correspond to a dry, firm and dark meat (Vergara, 2005). Other studies showed that β-AA administration reduces pH drop after slaughter due to anabolic metabolism (Gregory, 1998;Moloney & Beermann, 1996).…”

“…Different factors contribute to this inconsistency, such as final pH and temperature (Sañudo et al, 1989), lower concentration of heme pigment (Ferreira & Bastos, 1994;Warris et al, 1990), small quantity of oxy-myoglobin (Ramos & Silveira, 2002). Some studies using sheep have found no effect of ZH on color variables (Avendaño et al, 2006;Romero, 2011;Berge et al, 1990), but results from Dávila et al (2013) were similar to those of the present study. A possible explanation for the reduced lightness in the meat of ZH-treated sheep is the reduction in the amount of intramuscular fat (marbling), which is white in animals finished with high in energy rations (Wulf & Wide, 1999).…”

The effect of Zilpaterol hydrochloride (ZH) supplementation (0 vs. 0.15 mg/kg live weight) on the meat quality was evaluated in Katahdin x Charollais (32 KCh) and Katahdin x Dorper (28 KD) crosses. Lambs were fed a totally mixed ration with 14% crude protein (CP) and 2.9 Mcal EM/kg DM. Data were analyzed using a completely randomized 2 x 2 factorial design: 2 genotypes (KCh and KD) and 2 ZH levels (0 and 0.15 mg/kg live weight). No interaction was found between ZH and the genotypes. The breed of the sire (BS) did not affect most of the meat traits, only KCh crosses had higher color values (L* = 34.0±0.6 vs. 35.6±0.6; a* = 13.4±0.3 vs. 14.9±0.4; b* = 5.6±0.3 vs. 6.6±0.4; h* = 20.8±0.9 vs. 23.0±0.09; C* = 14.7±0.4 vs. 16.4±0.5), more fat (11.2±0.5 vs. 11.9±0.5) and less protein (21.3±0.1 vs. 21.8±0.0) than KD. ZH meat had lower values (P < 0.001) than meat from the control animals: L* (31.9±0.6 vs. 37.7±0.6), a* (12.9±0.4 vs. 15.5±0.4), h* (15.1±0.9 vs. 28.6±0.9) and C* (13.5±0.5 vs. 17.7±0.8). ZH increased shear force on meat (5.4±0.2 vs. 3.7±0.2 kgf), and produced less fat (9.7±0.5 vs. 12.5±0.5%) and bone (23.2±0.3 vs. 24.6±0.2%), but more muscle (65.8±0.5 vs. 61.2±0.4%). Zilpaterol hydrochloride use in lamb production caused leaner yield and more protein retention, at the expense of reducing meat sensory qualities.

“…However, none of these studies reported the effect of SBO or other vegetable oil on the pH of the LM. Conversely, other studies evaluating ram lambs (Awawdeh et al, 2009;Francisco et al, 2015), male lambs (Dávila-Ramírez et al, 2013), and male kids (Najafi et al, 2012) reported that loin pH at 24 h postmortem was not affected by SBO addition to finishing diets. Lambs evaluated by Dávila-Ramírez et al (2013) had similar genotype, age, feeding, and handling to ewe lambs used herein, although Dávila-Ramírez et al (2013) used male lambs during the summer compared with ewe lambs fed during the winter in the current experiment.…”

The aim of the present study was to evaluate the impact of zilpaterol hydrochloride (ZH; 0 or 10 mg/lamb daily) and soybean oil (SBO; 0 or 6%) supplementation on feedlot performance, carcass traits, and wholesale cut yield of 32 Dorper × Pelibuey ewe lambs (30.55 ± 2. 57 kg of initial BW). Lambs were blocked by BW and randomly assigned to treatments under a randomized complete block design with a 2 × 2 factorial arrangement. After a 34-d feeding period, all ewes were slaughtered. No ZH × SBO interactions were detected (P ≥ 0.11) for the variables evaluated. In the overall feeding period and first 17 d of experiment, feedlot performance was not affected (P ≥ 0.26) by ZH supplementation, but from d 18 to 34, ZH increased (P ≤ 0.03) total gain, ADG, and G:F without affecting DMI (P = 0.58). Also, ZH increased (P ≤ 0.02) HCW, cold carcass weight, dressing percentage, LM area, and leg perimeter. Lung weight as percentage of final BW decreased (P = 0.05) whereas other noncarcass components and wholesale cut yields were not affected (P ≥ 0.06) by ZH supplementation. Inclusion of SBO did not affect (P ≥ 0.08) feedlot performance or wholesale cut yields. The LM pH at 24 h postmortem as well as liver and peritoneum percentages were decreased (P ≤ 0.05) by SBO supplementation, but no other carcass characteristics or noncarcass components were affected (P ≥ 0.08) by SBO. In conclusion, feedlot performance and carcass characteristics were not altered by the interaction of ZH × SBO. However, ZH alone increased the growth of ewes during the last 17 d of the feeding period. Likewise, carcass characteristics of economic importance (i.e., HCW, dressing percentage, LM area, and leg perimeter) increased with ZH supplementation. In general, feedlot performance, carcass traits, and wholesale cut yields were not altered by including 6% of SBO in the finishing diet of ewe lambs.

Effects of dietary ferulic acid on growth performance, carcass traits and meat quality of heifers

et al. 2020

BACKGROUND: Ferulic acid is a natural occurring compound with antioxidant and antimicrobial bioactive properties, and recently was proposed as a new alternative growth promoter in meat-producing animals without changing meat quality parameters. The present study aimed to evaluate the impact of two doses of ferulic acid (FA) on the feedlot performance, carcass traits, and physicochemical and sensory characteristics of meat quality in commercial heifers. Ninety heifers (3/4 Bos taurus; n = 270; body weight = 480 ± 10 kg) were randomly assigned to one of the following treatments (30 days): Control, fed with a basal diet; FA250 or FA500 offered the same diet further supplemented with FA at 250 or 500 mg kg −1 feed, respectively. Feedlot performance, carcass traits, and physicochemical and meat sensory characteristics were evaluated. RESULTS: FA supplementation increased average daily gain (ADG) by 21%, hot carcass weight by 1.8% and cold carcass weight by 1.6% with respect to the control (P < 0.05). FA500 treatment caused a decrease (P < 0.05) in some carcass traits. However, carcass characteristics of economic importance, such as cold carcass dressing and LT muscle area, were improved by FA250 supplementation (P < 0.05), causing a possible growth promoter effect. Physicochemical and sensory parameters of meat were not altered by FA supplementation (P > 0.05). CONCLUSION: Ferulic acid has the potential for use as a growth promoter additive in finishing heifers without negatively affecting the meat quality, as occurs with some synthetic growth promotants compounds used in animal production.
