Context Natural additives have been studied to increase animal performance and the quality of meat as alternatives to the use of antibiotics. Aims The present work investigated the effects of an essential oil blend (oregano, rosemary, lemon, garlic, eucalyptus, thyme and sweet orange) incorporated into the diet of crossbred heifers on the meat quality. Methods Thirty 12-month-old half-sister crossbred heifers (1/2 Angus vs 1/2 Nellore) with an average weight of 219.8 ± 8.8 kg were allocated in individual pens for 3 months. Three diets were tested: E0.0 (without the essential oil blend); E3.5 (with 3.5 g of the essential oil blend/animal.day); E7.0 (7.0 g of the essential oil blend/animal.day). The fatty acid composition (chemical) and profile of the Longissimus muscle were evaluated. In addition, the effect of aging (1, 7 and 14 days in vacuum packs at 2°C) on the colour, cooking and thawing losses, texture, and lipid oxidation were determined. Key results The essential oil blend did not affect (P > 0.05) the meat. It did not impact on the decrease in shear force, increased lipid oxidation or changes in colour with aging. Conclusions The chemical composition, water holding capacity, shear force, lipid oxidation, and fatty acid profile were not influenced by including the essential oil blend in the diet of heifers. Implications The use of low dosages of an essential oil blend could be applied in the diet of heifers, without affecting meat quality.

The objective of this study was to investigate the influence of genotype and the energy concentration in the diet on the sensorial and chemical quality of lamb meat. It was evaluated samples from 18 Morada Nova animals, 18 Santa Inez animals, and 18 Santa Inez x Dorper crossbred animals, totalizing 54 animals. The animals were kept with two diets, with energy concentrations of 10.46 and 12.56 MJ ME/kg, respectively, and slaughtered at 30 kg average weight. It was determined contents of protein, moisture, fat and ash, as well as cooking loss, water-holding capacity, shear force, and sensorial attributes of flavour, firmness and juiciness of the meat. Genotype influenced the chemical composition of lamb meat because animals of Morada Nova breed presented the highest moisture content, and Santa Inez x Dorper crossbred showed the highest protein percentage; however, there was no variation in the sensorial attributes of lamb meat of these three genotypes. The diet with the highest energy concentration provides meat with higher juiciness.

The effect of meat marinating with aqueous extract of Ilex meserveae dried leaves on dry-aged beef quality was investigated. Shear force, TBARS value, color parameters, fatty acid profile, and sensory properties were evaluated in beef cuts dry-aged for 21 days. The use of Ilex meserveae dried leaves as marinade at 0.5, 1.0, and 2.0% w / v did not affect the shear force and color parameters of dry-aged beef. The marinating of beef cuts with Ilex meserveae resulted in efficient prevention of lipid oxidation without impairing sensory acceptability. Aqueous extract Ilex meserveae can be applied as a natural ingredient in meat marinade to prevent peroxidation.

This study aimed to evaluate the effect of pre- and post-calving feed restriction on quantitative characteristics and lipid profile of meat from Morada Nova sheep. Twenty-four male lambs from single births only, with an initial weight of 10.0 ± 3.07 kg and at four months of age, were distributed in a randomized complete design, into three groups: pre-calving restriction (R-PRE; n=8) post-calving restriction (R-POS; n=8), and ad libitum feeding (ADLI; n=8). To make up the experimental treatments, the feeding regime applied previously on the sheep in the last third of pregnancy was considered. Treatments ADLI and R-POS were composed of lambs born from ewes fed ad libitum in the last third of pregnancy. Treatment R-PRE consisted of lambs born from ewes subjected to feed restriction in the last third of pregnancy at 60% of the recommended requirements for the group of ewes feeding ad libitum. For the lambs from treatments ADLI and R-PRE, the diet was supplied allowing 20% of the total supplied as refusals. For the animals from R-POS, a 30% restriction was imposed in relation to the animals feeding ad libitum. Animals were slaughtered with an average live weight of 25 kg. Afterwards, carcasses were chilled at 4 ºC for 24 h. Meat quality measurements were taken on the right side of each carcass; pH was determined immediately after slaughter and then again after chilling. Samples of the longissimus dorsi muscle were collected and frozen at -20 ºC. Moisture, ash, protein, total lipids, water-holding capacity, and cooking loss were determined in the meat samples, which were then subjected to the shear-force test. The sensory analysis was determined by the hedonic-scale test, in which sensory parameters of tenderness, juiciness, flavor, aroma, and overall acceptability and fatty acid profile were evaluated. There was a feed-restriction effect on protein, lipids, and water-holding capacity (P0.05). Saturated fatty acid contents were affected by the treatments (P0.05). Feed restriction does not compromise the physicochemical or sensory quality of Morada Nova lambs meat, but rather provides a meat product of good acceptance.

In this experiment, we investigated the effect of the supplementation of probiotic bacteria in the diet with inulin or dried Jerusalem artichoke tubers on the performance, meat quality, and fatty acid composition in the meat and backfat of fatteners. One hundred and forty-four crossbred pigs (PIC × Penarlan P76) were divided into six groups and fattened from 30 to 114 kg. The meat proximate composition, pH, color, texture, shear force, water-holding capacity, sensory attributes, and thiobarbituric-acid-reactive substances were measured. Normal post-mortem meat glycolysis was demonstrated and no meat defects were present. The chemical constituents in muscle tissues were similar, except for intramuscular fat (IMF). The addition of the prebiotics resulted in a higher IMF level, whereas a significantly lower content was found after the probiotic supplementation. Meat from both prebiotic groups was lighter, less red, and more yellow and showed a higher hue angle. The addition of both prebiotics significantly improved the antioxidant status of meat (by approximately 16% and 18%) and the water-holding capacity (less free water and higher M/T ratios), but reduced shear force (by 17%, p ≤ 0.05) and hardness (by 39% and 35%, respectively, p ≤ 0.05). The addition of the prebiotics and probiotics had no effect on any of the evaluated sensory attributes.

ObjectivesPackaging affects meat quality and durability because it can modify the environment around the product, creating conditions that delay deterioration reactions. During refrigerated storage of fresh meat, physical, chemical, microbiological and sensory changes may occur. Thus, to meet consumer needs, such as quality, convenience, and longer shelf life, it is necessary to extend the meat shelf life. An alternative is the use of edible coatings, which can be applied as primary packaging. This study aimed to evaluate the effect of chitosan and zein coatings on the meat quality of vacuum-packaged lamb meat stored for 57 d in two different temperatures.Materials and MethodsLongissimus muscle (right and left sides) from male lambs with the same diet and genetic group obtained from five animals were cut onto 2.5cm thickness steaks, randomized equally and distributed into three treatments: control (no coating), coated with chitosan (1% w/v)/0.5% glycerol (w/v) solubilized in 1% lactic acid (v/v) and coated with zein (4% w/w)/0.5% pink pepper oil (w/w) solubilized in 70% ethanol. Samples were then vacuum packaged (permeability rate: 2000 cm3/m224 h), stored for 57 d at two different temperatures (1°C and 5°C) and evaluated every 14 d by the following analyses: pH, instrumental color, water holding capacity (WHC), shear force, and TBARS- lipid oxidation. Lamb meat coated with zein or chitosan were submitted to a difference from the control test (the sample without any coating). Data were analyzed by ANOVA, and when a significant difference was found, SNK and Dunnet tests were applied for the quality analyses and sensory difference, respectively. For color analysis, ΔE = [(ΔL*)2 + (Δa*)2 + (Δb*)2]1/2 was also calculated.ResultsCoating, temperature and time showed significant differences (p < 0.05) for some of the studied variables except for WHC. A triple interaction was also found for all variables. At 1°C, ΔE from chitosan samples showed low values (ΔE = 1.95), meaning that color differences would not be noticed by time up to 29 d, although at 57 d values were 12.68. At the same temperature, zein containing samples when compared between 1 and 57 d, ΔE values varied from 5.51 to 11.42 where color changes were noticeable. At the end of 57 d, chitosan coated samples showed lower values of L* (lighter) and a* (less red) compared to zein coated and control samples. Generally, shear force values showed lower values by times, although chitosan showed higher values at 5°C. pH values varied from 5.09 to 5.48, temperature and coating did not affect this parameter, only time. For TBARS values, the highest value (0.238 mg MDA kg–1 sample) was found in the chitosan sample at 57 d at 5°C. Samples containing zein, for both temperatures, showed lower TBARS values if compared with chitosan. In this study, chitosan had a negative effect to lipid oxidation and shear force with higher values if compared to the others. In the difference from control test, lamb meat coated with zein was considered different with an average value = 4, which means moderate/great difference, (p < 0.05) from chitosan and control samples.ConclusionZein was more effective for showing lower values of TBARS and for not affecting shear force if compared to chitosan and control samples and can be used as an alternative for edible coating.

In a previous study regarding the effects of Kosher and conventional slaughter techniques on carcass and meat quality of cattle, it was speculated that electrical stimulation may have affected some of the meat qualities. Therefore, the objective of this study was to investigate the effects of electrical stimulation (ES) and non-electrical stimulation (NES) on key carcass and meat quality attributes of cattle slaughtered by Kosher vs. conventional slaughter methods. Carcass pH and temperature profiles over a 24 h post mortem (pm) period, meat shear force and water holding capacity were investigated in feedlot type cattle of comparable weights and breed types. Results showed that the combined effects of slaughter methods did not influence the meat quality attributes, but there were differences within the slaughter groups. The effect of ES on carcass pH lasted longer within the conventionally slaughtered group (12 h), than in the Kosher slaughter group (6 h). Muscle samples from the ES groups for both slaughter methods were more tender. Electrical stimulation also had a significant effect on the cooking loss from Kosher meat, while there was no significant difference in meat from the conventional slaughter methods. The results show that ES influences certain meat and carcass quality attributes of cattle, based on the way cattle were slaughtered.Keywords: Carcass pH, cooking loss, drip loss, electrical stimulation, shear force, slaughter technique

Our objective was to evaluate carcass traits and meat quality of quails from different strains and both sexes pertaining to three breeding-improvement programs. Quails from seven meat-type strains (UFV1, UFV2, UFV3, EV1, EV2, LF1 and LF2) and from one egg-laying (Japanese quail) strain (LAY) were slaughtered at 35 days of age. A completely randomised 8 (strain) × 2 (sex) factorial design was used for data analysis. Bodyweight, hot carcass weight and breast (musculus pectoralis major and m. pectoralis minor) and legs (thigh and drumstick) weights and their respective yields were determined. Ultimate pH, colour measurements, water-holding capacity, cooking loss and shear force were assessed. No difference in ultimate pH, shear force and hue was observed. The UFV3 strain had the greatest bodyweight at slaughter. The UFV3 strain had the greatest hot carcass weight in both sexes. The heaviest breasts were observed in both sexes of the UFV3 strain and in males of the UFV2 strain. The UFV3 quails had greater leg weight. The hot carcass yields of meat-type strains were greater than that of the LAY strain. The UFV3 and LAY females furnished a greater breast yield than did male quails. For males, the UFV1 strain had a greater yield of breast than that of LAY quails. The LAY quails presented the greatest yields of leg. The LAY quails had the least luminance, and the greatest water-holding capacity, cooking loss, red and yellow intensity, and chroma. In summary, meat obtained from meat-type strains had a greater water-holding capacity, lower cooking loss and greater luminance than that of the LAY strain. In addition, the meat-type strains grew appreciably faster, but the difference in yields of breast and leg meat between meat and layer strains was small. We conclude that meat-type strains, especially the UFV3, are more appropriate for enterprises focussed on meat production.

Ninety indigenous pearl guineafowls, (Numida meleagris galeata pallas) with average weight of 1.1kg were allocated at random to one of ten treatments to assess the effects of withholding feed alone or feed together with water o carcass shrinkage and meat quality. The ten treatment were slaughter from the feed lot (control), and sampling times of 6, 12, 18 and 24hour. Weights of live and carcass were taken to monitor shrinkage along with relevant meat quality parameters. Live and carcass weights of head, liver, kidneys and heart decreased progressively as the length of fasting period increased. The progressive decrease in weight were found to be more pronounced in animals from which freed together with water were withdrawn. After 6hours of fasting decrease in weights were found to be significant (P < 0.05). ultimate pH and index of water holding capacity of the meats also increased with the increase in length of fasting period with a concomitant decrease in cooking losses. The fat ratio of the carcass component decreased with increase in length of fasting. The implications of the effect of these observation on commercial guineafowl meat production in the tropics are discussed

Dietary partially destoned olive cake supplementation on performance, carcass traits and meat quality of intensively finished bulls was evaluated. Forty-five Limousin bulls, divided into three homogenous groups, received a diet with no supplementation (Control-CTR), 7.5% (Low Olive Cake-LOC), and 15.0% of olive cake supplementation (High Olive Cake-HOC). The trial was realized for 150 days; all bulls were individually weighed at the beginning, middle, and end of the trial, to calculate the individual average daily gain (ADG). At slaughtering, on each carcass, hot weight was recorded and, after 7 days, the pH and temperature were measured. On Longissimus lumborum muscle, color, cooking loss, and shear force of the cooked sample were determined. The chemical composition and the fatty acid content of muscle were determined. Olive cake inclusions (7.5% and 15.0%) increased (p < 0.05) the body weight, ADG, slaughter traits and intramuscular fat content and influenced (p < 0.05) the quality indices. The 15.0% of the inclusion reduced (p < 0.05) the cooking loss and shear force, and increased the unsaturated fatty acid content. The olive cake can be considered as a functional component in beef production and, in substitution to a quote of cereals into the diet of bulls, could be an opportunity to improve agriculture sustainability.

Abstract. Title of the paper: Carcass and meat quality of heavy pigs. II. Characteristics of meat and fat quality The aim of the 2nd part of the study was to present the shifts concerning the meat quality in various important muscles and the fatty acid profile in the backfat associated with a prolonged fattening. In total, 63 male castrates and 60 females (Piétrain-NN*German Landrace) were randomized to three groups with different live weights at slaughter (110, 135, 160 kg). The pH values, measured at different points in time, were not influenced by the live weight class. However, electrical conductivity as well as drip loss traits of the M. longissimus dorsi increased slightly in the upper weight class, whereas the cooking loss declined marginally. With increasing live weight there was in general a small tendency to a darker meat and a clear enhancement of the a* values, based upon higher pigment concentrations. Moreover, the water content diminished slightly, whereas the intramuscular fat content did not rise significantly within the same sex. Compared with 110 kg live weight, the collagen content and the percentage of soluble collagen decreased at 160 kg live weight whereas shear force values remained unaffected. In the sensory evaluation, pork chops of the 135 kg class received numerically the best and those of the 160 kg the worst ratings, but the differences were small and only exceptionally significant. Considering the fatty acid profile in the course of a prolonged fattening, there is a shift to smaller proportion of polyenic fatty acids in favour of oleic and palmitic acid.
