Any evaluation of breeds or production systems for beef must consider effects on production, carcass and meat quality characteristics. Holstein-Friesian (HF) cattle are bred for dairy traits only, while Norwegian dairy cattle (NOR) have been selected with some emphasis on beef characteristics. A comparison of production data from bulls of these two breeds has been presented previously (Kirkland et al., 2005). The objective of the present study was to evaluate specific carcass and meat quality parameters of HF and NOR bulls.

The aim of this study was to analyse the polymorphisms in the two promoter regions, P1 and P2, of the porcine Insulin-like Growth Factor 2 (IGF2) gene and to investigate the effect of IGF2 genotypes on meat quality traits in the Italian autochthonous Suino Nero Lucano pig. Three polymorphic sites were analysed and only two of the eight potential haplotypes were observed in the Suino Nero Lucano pig population: A haplotype (–366A – –225G – –182C), and B haplotype (–366G – –225C – –182T). Muscle mass and meat quality characteristics were analysed in 30 castrated pigs (10 for each of the three IGF2 genotypes: A/A, A/B, and B/B). According to the results, B/B animals, at the same carcass weight, showed the highest Longissimus lumborum and Psoas weight (P < 0.05), whereas A/A animals showed a higher intramuscular fat percentage and lower Warner–Bratzler shear force, drip loss, and polyunsaturated fatty acids content. Meat from B/B animals showed also a higher L* value and myoglobin and deoxymyoglobin percentage compared with meat from A/A ones (P < 0.05).

ObjectivesNaturSafe® (Diamond V, USA) is a Saccharomyces cerevisiae fermentation product developed as an animal feed supplement for the further manufacture of nutritionally balanced feeds for beef cattle. This immune support product (Association of American Feed Control Officials number 96.8, 73.046 and International Feed Name number 7–05–520, 8–08–034) has been specifically formulated to optimize beef cattle health and performance, antibiotic stewardship, and food safety. Research has shown that NaturSafe supports optimal rumen and liver health, overall health and immune function, consistency of feed intake, daily gain, feed conversion, and antibiotic effectiveness. As no research previously has assessed the impacts of this feed ingredient on the quality of meat, the objective of this research was to characterize the effects of feeding NaturSafe on meat quality characteristics in beef.Materials and MethodsCrossbred steers (N = 60, n = 12 per treatment; mean hot carcass weight = 421 kg), through an antibiotic free production system, were individually fed diets containing 12, 15, or 18 g/d of NaturSafe or a control diet without (–AB) antibiotics or a control with antibiotics (+AB; 330 mg monensin + 110 mg tylosin·steer–1·d–1) for 112 d. Strip loins were collected and aged for 13 or 29 d postmortem prior to fabrication. Steaks (m. Longissimus) were then evaluated for Warner-Bratzler shear force, pH, sarcoplasmic calcium concentration, troponin-T degradation, fatty acid profile, proximate composition, sarcomere length, total collagen and insoluble collagen. After each aging period, steaks were evaluated for lipid oxidation, and color characteristics (L*, a*, b*, discoloration percentage, and percentage surface oxymyoglobin, metmyoglobin and deoxymyoglobin), during and/or after a 7 d simulated retail display period. A subset of samples at various aging and retail display periods were analyzed for lactic acid bacteria (LAB), psychotrophic plate counts (PPC), and aerobic plate counts (APC). Animal was considered the experimental unit and hot carcass weight and marbling score were used as covariates in the analysis.ResultsTreatment had no effect on pH, sarcomere length, troponin-T degradation, fatty acid profile, proximate composition, total collagen, insoluble collagen, LAB, PPC, APC, lipid oxidation, oxymyoglobin percentage, or metmyoglobin percentage. Meat from cattle fed 18 g/d of NaturSafe was (1) equal to–AB controls and had higher shear force values compared to all other treatments (P < 0.01), (2) had higher (P < 0.05) sarcoplasmic calcium levels than +AB controls and cattle fed 12 g of NaturSafe/d, (3) was redder (higher a* values, P < 0.05) than all other treatments, and (4) was yellower (higher b* values, P < 0.01) than the 12 or 15 g dose and the–AB control. There were no differences among treatments fed NaturSafe for lightness (L*) at either aging time. There were no differences for meat from animals fed 12 or 15 g NatureSafe/d, except deoxymyoglobin percent and discoloration, which were both minimal. Discoloration values were low for all treatments (< 10%).ConclusionThese data indicate that feeding NaturSafe had few discernible effects on meat quality characteristics.

The objective of this study was to compare the quality characteristics of current plant-based protein ground beef alternatives (GBA) to ground beef (GB) patties of varying fat percentages. Fifteen different production lots (n = 15 / fat level) of 1.36 kg GB chubs of three different fat levels (10%, 20%, and 27%) were collected from retail markets in the Manhattan, KS area. Additionally, GBA products including a foodservice GBA (FGBA), a retail GBA (RGBA), and a traditional soy-protein based GBA (TGBA) currently available through commercial channels were collected. Consumers (n = 120) evaluated sample appearance, juiciness, tenderness, overall flavor liking, beef flavor liking, texture liking, and overall liking. Additionally, samples were evaluated for color, texture profile, shear force, pressed juiciness percentage (PJP), pH, and fat and moisture percentage. All three GB samples rated higher (P &lt; 0.05) than the three GBA samples for appearance liking, overall flavor liking, beef flavor liking, and overall liking by consumers. Similar results were found with trained sensory panelists, which rated the GBA as less (P &lt; 0.05) juicy, softer (P &lt; 0.05), and lower (P &lt; 0.05) for beef flavor and odor intensity and higher (P &lt; 0.05) for off-flavor intensity than the GB. Moreover, the GBA had less (P &lt; 0.05) change in shape through cooking and a lower (P &lt; 0.05) percentage of cooking loss and cooking time than the GB. Also, the GBA all had lower (P &lt; 0.05) shear force and PJP values than the GB. The color of the GBA differed (P &lt; 0.05) from the GB, with the GB samples being more (P &lt; 0.05) red in the raw state. These results indicate that the GBA provide different eating and quality experiences than GB and should thus be considered as different products by consumers and retailers.
