Analysis Of Results

The study was carried out on 119 hybrid grower-finisher pigs that were divided into 5 experimental groups. The analysis covered carcass and meat quality traits of crossbred pigs produced by mating Polish Large White × Polish Landrace crossbred sows with boars of either purebred Pietrain (P) or crossbreds of Line 990 × Pietrain (LP), or Pietrain × Line 990 (PL), or Duroc × Pietrain (DP), or Pietrain × Duroc (PD). The analysis of results which include the effect of the RYR1 gene polymorphism showed that porkers descending from Pietrain boars (P) had a higher meat content in the carcass and a larger loin eye area in comparison with porkers descending from DP and PD boars, and a larger loin eye area in comparison with porkers descending from boars that were LP crosses. Meat of porkers descending from Pietrain boars had lower water-holding capacity (WHC) and higher lightness (L*) in comparison with porkers descending from crossbred boars where the Pietrain breed was used on the paternal side (LP and DP). Meat of porkers descending from Pietrain boars had a lower content of water-soluble protein compared to other groups with a 25% share of the Pietrain breed. In addition, no significant influence of the position effect on carcass and meat quality was found out in porkers obtained from the crossing of sows of the White breed with crossbred boars descending from two-way crosses of the Pietrain breed with Line 990 (LP and PL) and with the Duroc breed (DP and PD).

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.

Despite the increasing interest in the welfare of animals during transport, very little is known on the response of local pig breeds to the transport procedures. This study aims to compare the effect of short journey on behaviour, blood parameters, and meat quality traits in 51 Apulo-Calabrese and 52 crossbreed [Duroc × (Landrace × Large White)] pigs. All the animals were blood sampled five days before delivery (basal condition) and at exsanguination for the analysis of creatine kinase, cortisol, glucose, lactate, albumin, albumin/globulin, total protein, urea, creatinine, aspartate aminotransferase (AST), alanine aminotransferase, alkaline phosphate, sodium, and potassium. Post mortem pH, color, drip loss, cooking loss, and Warner-Bratzler shear force were measured at different times in longissimus thoracis samples. Univariate and multivariate analyses showed that glucose, albumin/globulin, urea, and AST at exsanguination were influenced by the genetic type. Apulo-Calabrese showed the highest increase in blood values of lactate, creatinine, sodium and potassium after the short distance transport. Behavioural occurrences were similar in both genetic types during unloading and lairage. Small differences were observed for meat quality although significantly higher a* and lower L* were found in Apulo-Calabrese pigs, showing meat with a deeper red colour than crossbreeds.

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).

Substantial Interest

There has been substantial interest in the possible increased usage of the Duroc by the British pig industry. This followed several reports which indicated improved meat quality traits and advantages for Duroc cross females in sow productivity. An evaluation of productivity, carcase and meat quality traits of Duroc crosses was carried out as the second trial at the Stotfold Pig Development Unit.Large White x Landrace, Duroc x Landrace and Duroc x Large White females were mated to either Large White, Duroc x Large White or Duroc males to produce slaughter generation pigs. Sibling same sex pairs of entire males, castrated males and females were reared on either ad libitum or restricted feeding regimens to slaughter weights targeted to produce carcases of 55 kg, 65 kg and 85 kg.
