Due to the growing interest in the production and consumption of wild boar meat, the quality attributes of meat products should be well established. To characterize the quality of wild boar cross meat, two males and two females reared in the same environment were slaughtered at an average of one year of age, and meat samples were was collected and analyzed for different parameters such as for moisture, pH value, protein, fat, iron, phosphorous, calcium, water holding capacity through the measure of cooking loss. Data obtained for live body weight, carcass biochemical characteristics, and meat quality traits were submitted to one-way analysis of variance (ANOVA) using a general linear model (uni-variate) in Statistical Package for Social Sciences (SPSS) computer program and the level of significance was determined observing the probability value (p) obtained through ANOVA of respective traits. To study the association among nutritive values and body parts, Pearson’s correlation coefficients were determined using in Statistical Package for Social Sciences (SPSS) computer program. The pH values were found to be in the range of 5.78 to 5.90. Moisture, total ash, fat, and protein contents were observed to be in the range of 71.38 to 73.57 %, 0.89 to 1.10 %, 4.34 to 5.54 %, and 16.73 to 18.84 % respectively. Iron, phosphorous, and calcium content were found to be in the range of 1.94 to 2.94 mg/100g, 20.17 to 37.57 mg/100g, and 170.68 to 190.88 mg/100g respectively whereas cooking loss was in the range of 31.59 to 26.88 %. Sensory evaluation of meat samples was examined by a group of panelists according to the hedonic rating test. The consumer preference was similar to both types of meat samples (male and female). The overall acceptance; however, were higher in female samples than in male samples due to boar taint evident during the cooking or eating of pork derived from non-castrated male pigs once they reach puberty. The comparison of wild crosses among available commercial pigs and indigenous pigs is warranted for further studies with an appropriate and defined production system to obtain lean meat as per the consumer preferences which could be extensively used in commercial pig production to provide high-quality pork.

Fabp Gene

The polymorphisms of A-FABP gene which associated with meat quality traits of beef cattle divided in five groups(Qingyang native beef cattle group, Pingliang native beef cattle group, Qinchuan beef cattle group, South Devon beef crossbreed group, Simmental beef crossbreed group) in Gansu was studied. Three types of bands defined as genotypes GG, GC and CC were discovered in the study. According to the results we could find the mutation of c. 408 g > c existed in A- FABP gene’s exon3 area by sequencing analysis of gene in three different kinds. The analysis of A-FABP gene polymorphisms associated with meat quality traits like pressing lose, shear force, cooking loss, marbling score, meat color and pH value, showed that pressing loss with genotype GG was significantly greater than genotype CC (P less than 0.05), shear force with genotype GG was significantly greater than genotype GC and genotype CC (P less than 0.01), cooking loss and pH value with genotype GG were significantly greater than genotype GC (P less than 0.05) and genotype CC (P less than 0.01). This mutation of A-FABP gene could be considered as a locus associated with meat quality traits.

Abstract The objective of this study was to investigate a possible relationship between blood parameters related to animal welfare and defined beef meat quality characteristics during winter and summer seasons in one small-scale slaughterhouse. At exsanguination, blood samples were collected, and serum concentrations for total proteins (TP), albumin and C-reactive protein (CRP) were evaluated. After 24 h of chilling, ultimate pH was measured and meat samples were used for drip loss and cooking loss determination. Dehydration was not observed during seasons, while elevated concentrations of TP accompanied by higher CRP values pointed to summer as a more stressful season. Analysing the meat quality parameters, it was observed that during the two seasons, ultimate pH values were in the range for normal meat acidification, but values for drip and cooking loss were significantly increased during the summer season. In conclusion, CRP could be used as potential biomarker for beef meat quality estimation, in the first instance drip loss and ultimate pH.

Meat Samples

Indigenous chicken breeds have showed slower growth rate and yield lower meat production, compared to commercial broilers. However, their meat quality is valued by modern consumers. The present study aimed at analyzing the quality traits of breast meat samples of Noi broilers, one of the famous indigenous chicken breeds in Vietnam. A total of 355 breast fillet samples were collected to evaluate quality meat traits such as pH, surface color, drip loss, and cooking loss at different time points of 3, 24, and 48 hours after slaughtering as well as to analyze chemical compositions such as dry matter, crude protein and ether extract. As result, sex and cold-storage time significant affect some of quality traits of breast meat, whereas their interaction did not associate among the observed properties. After 3 hour-storage, the pH value was determined at 5.63, then decrease to 5.56 and 5.55 after 24 and 48 hours, respectively. The color values (L*, a*, and b*) were in the normal range reported from previous studies. Meat samples of two sexes did not vary in the cooking loss and drip loss values, whereas it was significantly different due to cold-storage time. The ether extract content of the meat was found negatively correlated with the cooking loss. The higher dry matter content of breast meat resulted in the lower drip loss value after 3h coldstorage (r=-0.12, P<0.05). There is a negative relationship between L* and a*. The variation demonstrated in this study can be used in breeding schemes in order to improve meat quality of Noi chicken lines.

<b>The purpose of the study was to determine the phenotypic correlations between meat quality traits in Popielno White rabbits. The experimental material consisted of 93 Popielno White rabbits (49♀; 44♂). From weaning at 35 days of age until 84 days of age, the animals were housed in a battery system and fed ad libitum with a complete feed containing 10,2 MJ of metabolic energy, 16,5% total protein and 14% crude fibre. The rabbits were slaughtered at 84 days of age with a body weight of about 2,6 kg. The research material was the meat of longissimus lumborum muscle. Meat quality characteristics, i.e. meat acidity, meat colour, shear force, meat texture and cooking loss, were examined. The results were analysed using the SAS package (2014). Many statistically significant relationships were found between the meat quality characteristics of Popielno White rabbits. The results indicate that potential selection towards a change in pH value may adversely affect the meat texture of Popielno White rabbits. Selection to improve the colour of the meat of this breed may have a negative effect on its shear force, hardness and cooking loss. Selection to improve shear force will improve the other texture profile parameters. An improvement in the meat texture parameters of Popielno White rabbits will lead to an improvement in the cooking loss value. Dependencies among meat quality traits in Popielno White rabbits are high enough to be useful in selecting an appropriate breeding method. </b>

The aim of the research was to investigate the influence of terminal sire line (TSL) and male category (MC) on carcass and meat quality of commercial fatteners. The study was performed on 180 pigs originating from three terminal sire lines: A (Pietrain × Large White), B (pure Pietrain), and C (Pietrain × Duroc × Large White), being assigned to three groups according to MC: immunocastrates (IC, n = 60), surgical castrates (SC, n = 60) and entire males (EM, n = 60). TSL affected most of the carcass and meat quality traits, together with the androstenone concentration. At the same time, MC had a significant effect on fat thickness, ham circumference, drip loss, cooking loss and androstenone and skatole concentrations. A significant interaction effect was observed for carcass length and ham circumference, as well as for most of the measured meat quality traits (except cooking loss, CIE L*, CIE b*, and Warner Bratzler Shear Force (WBSF)). Among the three investigated sire lines, immunocastration was shown to be most beneficial for fatteners sired by the TSL C. However, if deciding to raise EM, fatteners from the TSL B are recommended in terms of carcass and meat quality, although strategies for avoiding boar taint in their carcasses must be taken into consideration.

The aim of this study was to investigate the possible harmful effect of Sarcocystis parasites on bovine diaphragm meat quality. Meat samples were collected from 120 bulls aged 20–24 months. Meat quality was investigated using microbiological and physico-chemical (RP-HPLC, GC) methods 48 hours after slaughter. Sarcocystis infection was associated with increased fat content, lightness L* and drip loss, and decreased ash and protein percentages. Infection also had a significant effect on the amount of amino acids (AAs), which slowly decreased as the number of sarcocysts increased. The total amount of AAs correlated with glutamic acid content (R = 0.966, P &lt; 0.05). Heavily infected samples contained significantly lower amounts of putrescine, histamine, spermine and spermidine (P &lt; 0.05) and<br /> a noticeable increase in the total count of aerobic microorganisms, but no change in the numbers of E. coli and coliform bacteria in comparison with no infected samples. Sarcocysts in beef diaphragms did not cause serious changes in the technological quality of the meat, but the biological quality of infected meat was reduced.

Nutrient Amounts

The cultivated peanut (Arachis hypogaea L.) is one of the most widely consumed legumes globally due to its nutrient content, taste, and affordability. Nutrient composition and consumer preference were determined for twenty local farmer (landrace) and commercial peanut varieties grown in the Nakaseke and Nakasongola districts of the central wooded savanna of Uganda through sensory and laboratory evaluation. Significant differences in nutrient content (p < 0.05) among peanut varieties were found within and across sites. A significant relationship between nutrient content and consumer preference for varieties within and across sites was also realized (Wilk’s lambda = 0.05, p = 0.00). The differences in nutrient content influenced key organoleptic characteristics, including taste, crunchiness, appearance, and soup aroma, which contributed to why consumers may prefer certain varieties to others. Gender differences in variety selection were significantly related to consumer preference for the crunchiness of roasted peanut varieties (F = 5.7, p = 0.016). The results imply that selecting different varieties of peanuts enables consumers to receive different nutrient amounts, while experiencing variety uniqueness. The promotion of peanut intraspecific diversity is crucial for improved nutrition, organoleptic appreciation and the livelihood of those engaged in peanut value chains, especially for the actors who specialize in different peanut products. The conservation of peanut diversity will ensure that the present and future generations benefit from the nutritional content and organoleptic enjoyment that is linked to unique peanut varieties.

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. Key words: Average daily gain, carcass characteristics, European and British crossbred, feed to gain ratio, meat quality, Wagyu crossbred cattle
