Growth performance, carcass characteristics and meat quality of European and British crossbred (EBC; no Wagyu genetics; 28 heifers and 30 steers) cattle were compared with crossbred cattle with 75% Wagyu genetics (WC; seven heifers and 14 steers) to determine the influence of Wagyu genetics on marbling grade of beef cattle fed barley-based diets in a factorial design experiment. Weaned calves (250 d average age) were fed, one of two diets (diet 1, 35% barley grain; diet 2, 40% hay cubes on DM basis, with barley silage, protein and vitamin/mineral premix) for 84 d and then fed diet 1 until they weighed 394 to 432 kg. All cattle were finished on an 80% (DM basis) rolled barley diet and slaughtered. Carcasses were graded and samples procured for meat quality and Warner–Bratzler shear force determination. Number of days on backgrounding diets to arrive at target weight (380 kg) was greater (P < 0.05) for the WC cattle, owing to relatively lower ADG, but days on the finishing diet were fewer for these cattle, compared with EBC cattle. Warm carcass yield (dressing percent) was greater (P < 0.05), but backfat depth was lower (P < 0.05) for WC cattle relative to that of EBC cattle, yet proportion of lean meat yield was similar. Eighty three percent of WC cattle carcasses had Canada AAA (small or more) marbling grade compared with 13% for EBC cattle carcasses. Mean shear force of meat samples from EBC and WC cattle was 4.2 and 3.8 kg, respectively. Results indicated that the extent of carcass marbling can be increased by incorporating Wagyu genetics but age at slaughter of WC cattle was 19 d greater than that of EBC cattle and carcass size was reduced.

Feeding trials were conducted in two years to compare growth performance, carcass characteristics and quality of meat from beef cattle with 0, 50 or 75% Wagyu genetic influence. The cattle types used in the two years of the study were Continental crossbred steers (0% Wagyu), cattle with 50% Wagyu influence (Wagyu/Angus crossbreds) and 75% Wagyu influence (containing 25% from other European breeds). Cattle were housed in individual pens in the first year and in group pens in the second year. Cattle were fed a backgrounding diet containing 35% barley grain and 65% barley silage with protein, mineral and vitamin supplements until they weighed more than 380 kg, after which they were adapted to a finishing diet consisting of 80% barley and 20% barley silage with mineral and vitamin supplements. Cattle were weighed every 4 wk and at the end of the finishing period they were processed and carcass information was obtained. A three-rib section (10–12) was removed from 41 (year 1) and 44 (year 2) carcasses selected randomly from each group, and Warner–Bratzler shear force was determined. The year-by-cattle type interaction was significant for most parameters; thus all the data were also analysed by year using weight of cattle at initiation of the feeding trial as a covariate for the backgrounding and finishing phases of growth and using carcass weight and back fat depth as covariates for carcass and meat-quality parameters. Weight at the start of the trial influenced most growth parameters and age at slaughter. Continental crossbred steers had higher (P < 0.05) ADG than Wagyu crossbred cattle during the finishing phase (1.47 vs. 0.82 kg d−1) in year 1, but not in year 2. Carcass weights of 75% Wagyu crossbred cattle were lower (P < 0.05) than those of Continental crossbred steers in both years. Warner–Bratzler shear force values were less than 5.3 kg to shear cores of 19 mm diameter. However, 92% in year 1 and 71% in year 2 of the carcasses from Wagyu crossbred cattle graded Canada AAA, and contained more than a "small" amount of intramuscular fat. Thirty percent of the carcasses from Wagyu crossbred cattle in year 1 graded Canada Prime. Only 30% of Continental crossbred steers in year 1 and 10% in year 2 graded Canada AAA. Wagyu genetic influence enhanced marbling in beef cattle without loss in carcass size for the 50% Wagyu steers. Key words: Wagyu, Carcass characteristics, Warner–Bratzler shear force

Effect of nutritional regimen including limit feeding and breed on growth performance, carcass characteristics and meat quality in beef cattle. Can. J. Anim. Sci. 92: 327–341. The effects of nutritional management regimen and breed on growth performance, carcass attributes, and meat quality were evaluated in 68 British (BRIT) and Continental (CONT) crossbred steers, managed on one of three nutritional regimens: (1) ad libitum access to a 77% corn diet (ALGRAIN), (2) limit feeding initially of the 77% corn diet, followed by ad libitum access to the 77% corn diet (LFGRAIN), and (3) limit feeding initially of a 90% haylage diet, followed by ad libitum access to the 77% corn diet (LFHAYL). Nutritional regimen by breed interactions (P<0.02) were present for average daily gain, dry matter intake (DMI), gain to feed, and shear force. LFHAYL regimen decreased gains to a greater extent for BRIT steers than CONT steers managed on ALGRAIN or LFGRAIN. Feed intakes were similar across nutritional regimens for CONT steers, while DMI was depressed in BRIT on LFHAYL as compared with steers started on ALGRAIN or LFGRAIN. Gain to feed was greater in BRIT cattle on LFGRAIN vs. ALGRAIN, while gain to feed was similar in CONT started on grain (ALGRAIN, LFGRAIN). Shear force was lower for beef from LFHAYL BRIT vs. beef from BRIT on ALGRAIN or LFGRAIN, while the converse was true for CONT. Limit feeding of a high-energy diet may be appropriate for cattle of British background to reduce feed input costs, while ensuring tenderness.

Abstract Carcass and meat quality of male and female Anatolian water buffaloes were investigated using 10 carcasses from each gender. Gender had no influence on carcass characteristics, except warm carcass weight, which was 13% higher in males compared to females. Meat from male water buffaloes had higher ultimate pH and lightness (L*), but lower redness (a*) values than females. Meat samples aged for 21 days had lower values for expressed juice, cooking loss and Warner Bratzler shear force compared with those of 7-day aged ones. Meat samples aged for 21 days had higher L* value at 1 h and 24 h after cutting, a* value at 1 h after cutting compared with those of 7-day aged meat samples. Gender had no effect on meat sensory characteristics. Meat from male water buffaloes had higher proportions of C14:0, C18:3 n-3, C20:2 n-6, C20:3 n-3 and C20:4 n-6 and Σn-3 fatty acids and lower Σn-6/Σn-3 ratio compared with female water buffaloes.

Objective: This study aimed to determine the effects of stress during slaughter of beef cattle on physiological parameters, carcass, and meat quality at a Federal Inspection Type slaughterhouse located in the southeast of Mexico.Methods: A total of 448 carcasses of male Zebu×European steers with an average age of 36 months were included. Carcass assessment of presence of bruises and bruise characteristics was carried out on each half-carcass. Blood variable indicators of stress (packed cell volume, neutrophil to lymphocyte ratio, glucose, cortisol concentration) and meat quality parameters (pH, color, shear force, drip loss) were evaluated.Results: Of the 448 carcasses evaluated, 81% of the carcasses showed at least one bruise; one bruise was detected in 36.6% and two bruises in 27.0% of animals. Of the 775 bruises found, 69.2% of the bruises were grade 1 in region 3. Of the 448 carcasses studied, 69.6% showed hyperglycemia (6.91 mmol/L); 44.3% and 22.7% showed high (74.7 ng/mL) and extremely high (108.8 ng/mL) cortisol levels, respectively, indicative of inadequate handling of animals during preslaughter and slaughter. Of the carcasses evaluated, 90.4% had a pH ≥5.8 with an average of pH 6.3. In both pH groups, meat samples showed L* values >37.0 (81.6%) and a shear force >54.3 N; meat pH≥5.8 group showed a drip loss of 2.5%. These findings were indicative of dark, firm, and dry (DFD) meat. According to principal component analysis, grades 1 and 2 bruises in region 3 and grade 1 bruises in region 5 were highly associated with cortisol, drip loss, and color parameters b* and h* and were negatively associated with L*, a*, and C*.Conclusion: The bruises probably caused by stress-inducing situations triggered DFD meat. Appropriate changes in handling routines in operating conditions should be made to minimize stress to animals during the slaughter process to improve animal welfare and meat quality.

This study evaluated the effects of diets composed by cottonseed hull and meat aging on carcass characteristics and meat quality from young bulls fed on a high-concentrate system. Thirty crossbred bulls were assigned in a complete randomized experimental factorial design with three diets (CH21: cottonseed hull 210 g kg-1on a DM basis, CH27: cottonseed hull 270 g kg-1on a DM basis and CH33: cottonseed hull 330 g kg-1on a DM basis) and different aging times (24 hours and 3, 7 and 14 days). Meat from CH27 diets presented smaller LM moisture content (p < 0.05). Total lipids were smaller in CH33 diet (p <0.05). At 24 hours, CH21 diet presented smaller LM cooking loss than other diets. The increasing aging time reduced the shear force (p < 0.001) on the LM. Meat from CH27 diet presented the highest luminosity (p < 0.05) and yellowness values (p < 0.001). Three or seven aging days presented smaller values of LM luminosity. Likewise, the increasing aging time presented greater (p < 0.05) yellowness within the LM. Lipid oxidation was lower from CH21 diet (p < 0.001). The fatty acid composition on LM was similar among diets. The use of cottonseed hull could be useful strategies to improve the meat quality and lean beef production.

The objective of this research was to investigate the influence of maternal prepartum dietary carbohydrate source on growth performance, carcass characteristics, and meat quality of offspring. Angus-based cows were assigned to either a concentrate-based diet or forage-based diet during mid- and late-gestation. A subset of calves was selected for evaluation of progeny performance. Dry matter intake (DMI), body weight (BW), average daily gain (ADG), gain to feed (G:F), and ultrasound measurements (muscle depth, back fat thickness, and intramuscular fat) were assessed during the feeding period. Carcass measurements were recorded, and striploins were collected for Warner-Bratzler shear force (WBSF), trained sensory panel, crude fat determination and fatty acid profile. Maternal dietary treatment did not influence (p > 0.05) offspring BW, DMI, ultrasound measurements, percent moisture, crude fat, WBSF, or consumer sensory responses. The forage treatment tended to have decreased (p = 0.06) 12th rib backfat compared to the concentrate treatment and tended to have lower (p = 0.08) yield grades. The concentrate treatment had increased (p < 0.05) a* and b* values compared to the forage treatment. These data suggest variation in maternal diets applied in this study during mid- and late-gestation has limited influence on progeny performance.

Thirty-two double-muscled Belgian White-blue bulls, within a liveweight range of 542 (± 37) to 722 (± 31) kg, daily received 0 or 60 μg cimaterol kg−1 liveweight in a corn silage diet for 136 (± 29) d. Cimaterol slightly improved average daily gain from 1.28 to 1.38 kg (P > 0.05). Cold carcass weight and dressing were increased by cimaterol from 497.0 to 514.6 kg (P < 0.05) and from 71.0 to 72.9% (P < 0.001), respectively. Even in extremely meaty animals, cimaterol exerted a significant repartitioning effect towards more meat and less fat, both in the carcass and in the longissimus thoracis muscle. Cimaterol increased the shear force value from 37.1 to 52.7 N (P < 0.001) but had no effect on other organoleptical traits. Key words: Cimaterol, double-muscled bulls, growth, carcass, meat quality

This study aimed to explore the effects of beta-hydroxy-beta-methyl butyrate (HMB) on serum metabolic profiles and meat quality of muscles in Wenshi broiler chickens. Birds were fed a basal diet with an additional 0, 0.05, 0.10, or 0.15% HMB, respectively. Results showed that dietary HMB quadratically increased the average daily gain (P = 0.058) and decreased feed:gain (P &lt; 0.05) mainly in the starter phase. At 51 days of age, birds receiving 0.10% HMB diet exhibited less abdominal fat and more breast yield than the control (P &lt; 0.05). Moreover, dietary HMB quadratically decreased the L∗ value and drip loss in selected muscles (P &lt; 0.05) and increased the a∗ value in breast muscle (P &lt; 0.05). Serum metabolome profiling showed that the most differentially abundant metabolites are lipids and lipid-like molecules, including phosphatidylcholines. It was concluded that HMB improved growth performance and meat quality of muscle in broilers.

Aim of study: To evaluate the effect of different diets on carcass characteristics and meat quality from Mos free-ranged cockerel.Area of study: Galicia (NW Spain).Material and methods: Cockerels (n=75) were allocated to 3 groups (n=25) according to finishing diets: commercial fodder (CF), 50% wheat and 50% corn (WH) and 33% wheat and 66% corn (CR). Meat quality was assessed in terms of physicochemical, and nutritional features.Main results: The highest live and carcass weight were obtained in CF group. Meat from CF and CR groups were similar in moisture, protein and cholesterol content in drumstick cut, meanwhile in breast piece there were no significant differences (p>0.05) in intramuscular fat (IMF), ash, and lightness (L*). On the other hand, finishing diet affected L* and redness (a*) values, showing the highest L* values in meat samples from CF treatment (49.94 for drumstick) (p<0.01), whereas a* was superior in WH samples (11.30 and 4.61, for drumstick and breast, respectively) (p<0.001). Meat shear force test was not affected (p>0.05) by diets. Finally, the finishing feed affected (p<0.05) the fatty acid and amino acid profile in both cuts (drumstick and breast).Research highlights: Present study allowed to characterize for the first time Mos cockerels fed with different diets. Some carcass features obtained were higher than previous studies with other Mos categories, and some autochthonous and industrial breeds. Meat from cockerels was characterized by a high protein percentage and lower IMF.

Vitamin E Supplementation

Background: Carcass and sheep meat quality are influenced by several factors, such as race, age, slaughter weight, type of diet, and dietary supplementation. Objective: To evaluate the effect of castration and vitamin E supplementation on performance, carcass characteristics and meat of lambs slaughtered at 45 kg. Methods: Thirty-two male lambs (16 castrated and 16 not castrated) were fed diets with or without the inclusion of vitamin E. The animals had an average age of 180 ± 20 days and a mean weight of 25.1 ± 4.6 kg. Performance was evaluated for 56 days, and the animals were slaughtered when reaching a weight of 45 kg. The experimental design was randomized blocks based on initial weights, and variables were assessed by a 2x2 factorial design (castrated and intact, supplemented or not with vitamin E, with a probability of 5%). Results: Higher proportion (p<0.05) of visceral fat was found in castrated animals (kidney: 2.45%, inguinal: 0.57% and omental: 4.96%) than in intact animals (kidney: 1.25%, inguinal 0.27%. and omental 3.12%). The aged meat samples showed no color differences for any of the treatments, but there were differences in shear force for steaks aged for 7 days, where the castrated animals showed an average of 2.64 kgf and intact animals showed an average 3.29 kgf. The animals supplemented with vitamin E had lower shear forces in non-aged samples. Conclusion: Castration increased deposition of visceral and fat coverage but did not influence the cut yields and total carcass yield. The animals supplemented with vitamin E had lower shear forces in non-aged samples.
