The aim was to compare lambs at two different ages at slaughter (40 vs 100 days) and three breeds or crossbreeds including an Italian dairy breed (Comisana (Com)) and its crosses with the two meat breeds of Bergamasca (Ber × Com) and Suffolk (Suf × Com) with 20 male lambs per age per breed group. At both slaughter ages, crossbreeds were more productive, with higher liveweight (P = 0.02), carcass weight (P = 0.03) and dressing percentage (P = 0.04) than the Com group. Meat from the younger lambs showed lower C10:0, C14:0 and C22:0 (P < 0.05) and higher C18:1 (P < 0.01) concentrations, resulting in higher monounsaturated fatty acid (P < 0.01) and lower saturated fatty acid (P < 0.01) content. Moreover, their meat has lower redness (a*), yellowness (b*) and chroma (C*) values (P < 0.01). Crossbreeding dairy breed ewes with sires of high meat production breeds improves liveweight and carcass weight. Meat from younger lambs had lower intramuscular fat content and higher concentrations of polyunsaturated fatty acid.

Meat Quality Traits

Castration in beef cattle production has been proposed to reduce sexual and aggressive behaviour, increase carcass fat deposition, and improve meat quality traits, such as tenderness and juiciness. The aim of the present study was to evaluate the effects of the age of castration on performance, subprimal yield and meat quality of Nellore cattle raised on a pasture system. A total of 24 Nellore males were raised in a grass-fed system with Brachiaria brizantha since birth until slaughter (at 30 months old). Three treatments were assigned: castration at weaning (CW); castration at 20 months old (C20); and intact bulls (NoC). Males were weighed, and muscle and fat thickness were periodically evaluated by ultrasonography. The cold carcass weight, dressing and carcass pH (pH 24), and subprimal cut weights were recorded after 24 h of chilling. Samples of Longissimus lumborum (LL) were taken to measure meat quality traits. Animals that were castrated at weaning had lower bodyweight after 10 months of age with no changes in the supplement intakes, average daily gain, hot carcass weight and cold carcass weight compared with NoC. Intact males had greater cooking losses and carcass yield compared with others, with no differences for LL pH 24 according to the treatments. The castration did not change the LL muscle area, but decreased total forequarter, chunk, shoulder and eye of round weights, and increased the back fat over LL and rump fat. Animals castrated at weaning had higher marbling compared with others. In addition, regardless of age, castration improved tenderness, increased LL total lipids and decreased moisture compared with NoC. For sensory property, steers castrated at 20 months of age had lower juiciness, and NoC had a greater global sensory property compared with steers castrated at 20 months old. In conclusion, steers castrated at weaning had lower growth rate, final bodyweight and meat production compared with intact males. However, when castration was performed at 20 months, animals did not differ in most cases from castration at weaning and NoC. Tenderness was improved by castration, but sensory traits did not differ between groups.

High meat quality and specifically meat tenderness are desired traits by the consumers, however the environmental impact of meat production is becoming a relevant factor in the industry. Therefore, breeding of dual purpose cattle breeds may answer the high demand of meat production in the future. In this study we identified statistical differences between genotypes of CAST and CAPN1 gene variants with meat quality traits in a dairy breed (Nordic Red Cattle) and compared the results with beef breed (Aberdeen Angus). Our results show that the favorable alleles have not been selected in the studied dairy breed and thus could be used as a tool for improvement of meat quality. The genes were associated with specific meat quality traits (i.e. sensory juiciness, marbling score and meat color) also in the dairy breed. This supports the utility of known meat quality associated genetic variants to improve meat quality in dairy breeds.

Abstract. In this study, meat quality traits and fatty acid compositions of Hair Goat and Saanen × Hair Goat (G1) crossbred kids fattened under intensive, semi-intensive and extensive conditions were determined. For meat quality traits, differences in pH24 h, pH45 min, drip loss, water holding capacity, cooking loss and Warner–Bratzler peak shear force values of the experimental groups were not found to be significant. According to colour measurements at the 0th and 45th minute, the extensive fattening group of Hair Goat kids had greater lightness (L∗) values and the intensive fattening group of Hair Goat kids had greater redness (a∗) values. For intensive, semi-intensive and extensive fattening groups of Hair Goat kids, total saturated fatty acid contents of longissimus dorsi (LD) muscle samples were respectively measured as 19.28 %, 23.75 % and 23.35 %. Total monounsaturated fatty acid contents were respectively measured as 67.30 %, 66.22 % and 65.72 %. Total polyunsaturated fatty acid contents were respectively measured as 5.46 %, 3.06 % and 3.16 % and conjugate linoleic acid contents were respectively measured as 0.48 %, 0.55 % and 0.65 %. For intensive, semi-intensive and extensive fattening groups of Saanen × Hair Goat (G1) kids, total saturated fatty acid contents of LD muscle samples were respectively measured as 21.01 %; 21.98 %, 19.10 %; total monounsaturated fatty acid contents were respectively measured as 64.04 %, 64.33 %, 52.44 %. Total polyunsaturated fatty acid contents were respectively measured as 3.53 %, 4.89 % and 4.84 % and conjugate linoleic acid contents were respectively measured as 0.52 %, 0.58 % and 0.73 %. It was concluded that the extensive fattening group had greater conjugated linoleic acid contents than the other fattening groups.

Abstract. Title of the paper: Systematic crossbreeding as a tool to conserve endangered pig breeds Live conservation of purebred populations of old endangered pig breeds requires high financial subsidies because they are very inferior to actual commercial hybrids in overall economy. But subsidies may be considerably reduced if the endangered breeds can be integrated into regional crossbreeding schemes adapted to ecological production niches or designed for specific quality products. The aim of this study at the experimental station Relliehausen of Göttingen University was to compare the performance of two crossbred sows with the endangered breeds Saddleback (DS) and Bentheimer (BB) as dams sire (and LW/LR as dams dam) with commercial LW/LR-crossbred sows in their litter performance as well as meat production and quality traits of their progeny from the same PI(NN)- and (PI*HA)-terminal sires. 478 litters with 1,384 fattened and 1,037 carcass graded progeny of which about 600 underwent detailed carcass value and meat quality evaluations at a loin cross section and 48 with an additional sensoric test. Results show that in litter performance DS crossbred sows were comparable to LW/LR commercial sows but BB crossbred sows weaned 0.66 pigs less per litter. In FOM grading no significant differences were found between the three sow groups as well as between the two different terminal sires. This also applied for most meat quality traits but in intramuscular fat content unexpectedly the control pigs were the best and significantly superior to the BB-progeny. The typical highly significant quality differences due to the "Hampshire effect" were found between progeny of the (PI*HA)-boar as compared to PI-progeny. In a calculated overall economic value DS-progeny were 4–5 DM and BB-progeny about 8 DM per pig inferior to the commercial controls. These differences are only 1/5 to 1/10 of the purebred inferiority of the endangered breeds. These results should be confirmed by a field trial under more extensive conditions (e.g. outdoor sow- and ecological fattener management).

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).
