The present study was aimed at characterizing carcass and meat quality traits in Bandur/ Mandya ram lambs. Eighteen ram lambs were slaughtered at the age of six months by Halal method. The pre-slaughter weight (PSW), hot carcass weight (HCW) and dressing percentage based on PSW recorded were 13.49 ± 0.26 kg, 6.44 ± 0.14 kg and 47.77 ± 0.70 per cent, respectively. The mean loin eye area was 15.43 ± 0.64 cm2. The mean primal cut weights for leg, loin, rack, chuck, and breast and fore shank were 2.090 ± 43.35, 0.675 ± 29.40, 0.646 ± 28.82, 2.036 ± 47.35 and 0.601 ± 23.97 kg, respectively. The highest proportion of meat was recorded in leg (25.06%) and chuck (23.23%). The meat quality traits viz., pH, water holding capacity, Warner-Bratzler Shear Force value, cooking loss and back fat thickness were 6.35 ± 0.05, 49.74 ± 3.33 per cent, 3.75 ± 0.14, 26.01 ± 2.19 per cent and 0.26 ± 0.02 cm, respectively. The mean percentage values for proximate principles viz., moisture, crude protein, crude fibre, ether extract, and total ash were 72.10 ± 0.38, 19.76 ± 0.34, 0.24 ± 0.03, 7.23 ± 0.47 and 1.01 ± 0.04 per cent, respectively. Compared to earlier reports higher loin eye area measurement was observed in the present study indicating higher muscular development in Bandur ram lambs.

AbstractThe aim of this study was to analyze the association of polymorphisms in alpha-ketoglutarate-dependent dioxygenase (FTO) and perilipin 2 (PLIN2) genes with carcass and meat quality traits in pigs reared in Poland. The research covered 578 sows that belong to the following breeds: Duroc, Hampshire, Polish Landrace, Pietrain, Puławska and Polish Large White. FTO (FM244720:g.400C>G) and PLIN2 (GU461317:g.98G>A) genes variants were determined by means of PCR-RFLP and ACRS-PCR methods respectively. Association between individual genotypes and analyzed traits was calculated by means of GLM procedure for Polish Landrace, Polish Large White and Puławska breeds separately and for all six breeds together in case of FTO gene. The results showed that FTO variants were associated with weight of loin without backfat and skin (WL), loin eye area (AL) and meat percentage (MP) in Polish Large White (P≤0.05), mean backfat thickness from 5 measurements (BFT) and pH measured 45 min after slaughter in m. longissimus dorsi (pH24 ld) as well as with water holding-capacity (WHC) in Puławska breed (P≤0.01). PLIN2 genotypes, however were correlated with WL and height of the loin eye (HL) in Polish Large White and Puławska (P≤0.05), AL in Polish Large White (P≤0.01) as well as luminosity (L*) in Puławska (P≤0.05) pigs. We observed most consistent relationships of PLIN2 SNP with intramuscular fat content (IMF) and WHC. In 3 analyzed breeds GG genotype was connected with highest values of these traits (P≤0.05).

This study was performed to analyze the difference between the meat properties classified into 5 ranges depending on Berkshire meat quality traits. Post-mortem pH24hr was positively correlated with water holding capacity, but negatively correlated with meat color, protein content, drip loss, and cooking loss. Berkshire gilt was discovered by higher population of RFN (reddish pink, firm, non-exudative), a normal meat class when compared to barrow, whereas DFD (dark, firm, and dry) was not detected and PSE (pale, soft and floppy, exudative) and RSE (reddish pink, soft and floppy, exudative) were found by a low number of individuals. It was assumed that Berkshire gilt is less susceptible to stress when compared with barrow. Therefore, from the results of this study, we suggest that Berkshire gilt is high possibility for production of good meat due to a forming ability for better meat quality than that of Berkshire barrow.

In this study, we aimed to detect the single nucleotide polymorphism (SNPs) of the chicken PRKAG3 gene and discern the potential association with meat quality traits. A total of 240 meat-type quality chickens were screened by using single-strand conformational polymorphism analysis (SSCP) and DNA sequencing. Two SNPs (g.1744G>C and g.3207A>G) were identified in chicken PRKAG3 with medium polymorphism (0.25C were significantly associated with water content, crude protein, and crude ash (P<0.05/0.01). The SNP genotypes g.3207A>G were significantly associated with water content, and crude protein (P<0.01). The results suggested that PRKAG3 gene is potential major genes or is in close linkage disequilibrium with the QTL affecting meat quality traits in this population of chickens.

Corticosteroid-binding globulin (CBG) is a plasma transport protein that has glucocorticoid-binding activity. In the present study, we identified CBG gene expression in several tissues of four pig breeds: Berkshire, Duroc, Landrace, and Yorkshire. Expression of CBG mRNA was detected in the liver of all four breeds, and was the highest in Berkshire pigs. We also found single nucleotide polymorphisms (SNPs) in the CBG gene from Berkshire pigs, including SNP c.919G>A, which corresponds to 307G>R. We analyzed the relationships between this CBG variant and various meat-quality traits. The SNP was significantly associated with backfat thickness, post-mortem pH24h, meat color [CIE a* (redness), CIE b* (yellowness)], water-holding capacity, fat content, moisture content, protein content, cooking loss, and shear force. However, the effects differed by gender: the values were significantly associated with almost all traits in gilts, whereas only cooking loss and shear force were shown significantly in barrows. The variant G allele was associated with decreases in backfat thickness, post-mortem pH24h, CIE a*, fat content, and cooking loss, but with increases in CIE b*, water-holding capacity, moisture content, protein content, and shear force. Because the general correlation between meat-quality traits were not validated in the present study, we suggest that certain SNP might be used in the restrictive application to distinguish meat-quality traits.

This study was conducted to investigate the effects of fattening duration on carcass and meat quality traits of Saanen x Hair Goat (G1) hybrid male kids fattened in intensive, semi-intensive and extensive fattening systems. Two different slaughter times (120 and 150 days) were applied. Slaughterhouse weights of the kids for 120 and 150-days were measured as 31.22 kg and 31.03 kg in intensive fattening, as 30.08 kg and 27.26 kg in semi-intensive fattening and as 28.69 kg and 28.72 kg in extensive fattening system respectively. Hot carcass weights were measured as 15.29 kg and 15.98 kg in intensive fattening, as 14.48 kg and 12.85 kg in semi-intensive fattening and as 13.85 kg and 13.8 kg in extensive fattening system respectively. With regard to meat quality traits of pH24, pH45, water holding capacity, passive water loss and cooking loss, significant differences were not observed between fattening systems and between fattening durations. Warner-Bratzler peak shear forces decreased with prolonged fattening duration and the greatest marbling score was observed in 150-day intensive fattening system.

To evaluate the effect of grazing cattle temperament on performance, as well as carcass and meat quality traits, exit velocity (EV) was assessed throughout two production cycles (PC1, n = 38 and PC2, n = 52). Individual EV determinations were assessed throughout each PC and then 100-days period averages were calculated for each animal. Animals were ranked based on their EV (EV-RANK) in the first 100-days period as SLOW, FAST and MEDIUM. The EV decreased from weaning to slaughter in FAST and MEDIUM (P &lt; 0.05); but did not change in SLOW (P &gt; 0.10). Initial liveweight was lowest in FAST and highest in MEDIUM (P = 0.03). DM intake (P = 0.08) and average daily gain (P = 0.94) were not affected by EV-RANK, but carcass subcutaneous fat thickness was lowest in FAST and highest in MEDIUM (P = 0.02). Longissimus muscle colour and shear-force were not affected by EV-RANK (P &gt; 0.05), but muscle glycogen content at slaughter was higher in MEDIUM than in SLOW or FAST (P = 0.047). No EV-RANK effects were observed in the present study on meat colour and shear-force. However, its effects on subcutaneous fat thickness and muscle glycogen could result in low meat quality of temperamental cattle under more stressful handling situations.

The study involved 110 hybrid grower-finisher pigs from Polish Large White x Polish Landrace sows sired by Pietrain breed boars and their crossbreds with the 990 line and Duroc. The aim of the study was to determine an association of the polymorphism of RYR1, myogenin (MYOG) genes and carcass meatiness level with carcass slaughter value and meat quality traits in hybrid pigs. Better meat quality was found in pigs of CC genotype at locus RYR1 than in those of CT genotype, with a similar carcass slaughter value and meat chemical composition. No significant differences were found in meat traits (carcass slaughter value) and quality between AA and AB genotypes at locus MYOG. Similarly, no significant differences were found between carcass meatiness ranges adopted in meat quality and its chemical composition, except for water holding capacity, which was higher in pigs with ⪬ 54% meatiness than in those with > 54%. Moreover, interaction was found between carcass meatiness range and RYR1 genotype in relation to backfat thickness and intramuscular fat content, as well as a connection between carcass meatiness range and MYOG genotype in relation to water-soluble protein content. The results indicate the need to continue selection work towards the elimination of allele T RYR1 gene’s in pedigree herds to improve meat quality in fatteners.

Abstract. The aim of the investigations was to analyse the share of myosin heavy chains (MHC) isoforms (type I, IIa, IIb, and IIx) in the longissimus thoracis et lumborum muscle derived from pigs of different RYR1 genotypes (TT – homozygous negative, CT – heterozygous, CC – homozygous positive). The composition of the MHC isoforms in the muscle tissue of the examined animals was referred to selected meat quality traits. It was revealed that the animals with the CT and TT genotypes were characterized by a significantly (P≤0.05) lower share of the type I and higher share of the type IIb MHC isoform in comparison to homozygotes CC. Inferior tenderness and water holding capacity of meat obtained from pigs susceptible to stress (TT) at 144 h after slaughter could have been associated, among others things, with the increased share of MHC isoform type IIb. The composition of MHC isoforms might be a useful indicator in breeding work in the selection of animals carrying the gene of susceptibility to stress.

The aim of the study was to find out the effect of different feeding systems on the fattening performance, slaughter and carcass characteristics, and meat quality of Norduz male lambs. Lambs were randomly divided into 3 groups of 15 each, as follows: 2M (2 meals/day), 4M (4 meals/day) and SF (self-feeder). Then, lambs were fed according to these regimes for 70 days to determine the feed conversion ratio, dressing percentage, carcass fatness and meat quality traits such as pH, color and water holding capacity. Although live weights and daily weight gains were found to be similar among the groups, significant differences were found in the daily feed intake (2M: 1.53 kg; 4M: 1.70 kg; SF: 1.89 kg) among groups (p<0.05). No significant differences were observed in slaughter and carcass characteristics except dressing percentage (2M: 49.69%; 4M: 50.59%; SF: 48.46%). Meat quality traits were also similar among groups, except for pH24h (2M: 5.77; 4M: 5.95; SF: 6.10) (p<0.01).

One-hundred and eighteen bulls slaughtered at Van city abattoir were evaluated to determine the effects of some pre-slaughter factors on meat quality traits. The effect of breed on meat quality traits was limited except for water holding capacity (WHC) and Brown Swiss cross bulls had higher WHC than Simmental cross bulls. Bulls aged 30 months and older had higher pH24h (6.05 vs. 5.76; p less than 0.001) and lower L* and b* values than younger bulls. Bulls that were transported from 300 km away had significantly higher pH24h (6.10 vs. 5.71; p less than 0.01) and lower L*, a*, b*, cooking loss, and WBSF than bulls with £125 km transport distance (p less than 0.05-p less than 0.01). Bulls that waited unrestrained in lots had higher pH24h and lower L*, b* and WBSF (7.06 vs. 5.31; p less than 0.01) values than those that were restrained while waiting in abattoir. Effects of age, lairage and waiting type on dark cutting incidence were also significant and average percentage of dark cutting was 24.78% (pH24h ³ 6.2). As a result, it was determined that the percentage of DFD carcasses was high and dark cutting was serious problem.
