  • The first aim of the study was to compare selected meat quality parameters in porkers without the gene $RYR1^T$ (ryanodine receptor gene). These were porkers slaughtered at 100 to 115 kg and 116 to 130 kg live weight. The second aim of the study was to determine the occurrence frequency of standard-quality meat (red, firm, nonexudative [RFN]) and the occurence frequency of defective meat (pale, soft, exudative [PSE] and acid, soft, exudative [ASE]). The analysis was conducted on the longissimus lumborum muscle in 114 crossbred porkers. The porkers were a cross of Camborough 22 sows and boars from lines 337PIC (Pig Improvement Company), Norsvin Landrace and Pietrain. All of the animals were provided with identical environmental and nutritional conditions. The average weight of the slaughtered animals in the light and heavy groups was 110 kg and 122 kg, respectively. Both groups had the same average post-slaughter meatiness (56.5%). A statistical analysis of selected meat-quality parameters did not show any significant differences between the weight groups. On the other hand, the classification based on carcass quality showed an occurence frequency of defective meat in heavier crossbred porkers (116 to 130 kg) that was three times higher than in those cross bred animals which weighed 100 to 115 kg when slaughtered. In porkers without the gene $RYR1^T$, the defective meat types PSE and ASE occurred with a frequency of 17.54%.

  • A study was conducted to investigate the possibility of improving the effectiveness of the existing method(s) to estimate the edible meat weight in live broiler chicken. Four. breeds of chicken, white Cornish broiler chicks(parent stock), Single Comb White Leghorn(SCWL) egg strain chicks (parent stock), and two reciprocal cross breds of these parent stocks were employed in this study. A total of 480 birds, 60 male and 60 female chicks for each breed, were used. Ten male and 10 female chicks from each breed were randomly sacrificed at 0, 2, 4, 6, 8 and 10 weeks of ages in order to measure the body weight, edible meat weight of breast and 1eg(thigh and drum-stick), various components of body weight and various body shape measurements. In addition, chemical analyses of edible meat were carried out. Results obtained from this sturd were summarized as follows. 1. The average body weights of White Cornish broiler chicks and SCWL egg strain chicks were 1.82${\pm}$0.048kg(X${\pm}$S.E.) and 0.67${\pm}$0.029 kg. respectively, at 8 weeks of age. The feed to gain ratio for White Cornish and SCWL chicks were 2.24 and 3.28, respectively, for 0 to 8 weeks of age. The reciprocal cross bred chicks (White Cornish ${\times}$ SCWL) showed intermediate values in both parameters.

  • 'Jangha' is a new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2014. The 'Jangha' cultivar originated in 2008 from a cross between 'Goha' and 'Elsinore' that showed excellent ever-bearing characteristics, including continuous flowering habit and high soluble-solids contents under long-day and high temperature conditions. This cultivar was initially named 'Saebong No. 6' after examining its characteristics and productivity in summer culture from 2010 to 2012. After two regional adaptability tests in 2013-2014, 'Jangha' was selected from Saebong No. 6 as an elite cultivar. The general characteristics of 'Jangha' include semi-spreading type, elliptical leaves, and moderately vigorous growth. The fruit are conical in shape, and red in color. 'Jangha' plants have 21.4 leaves, 55.8 fewer than 'Flamenco' plants. The soluble-solids content of 'Jangha' was 8.9%, which was 1.2% higher than that of 'Flamenco'. The average fruit weight of 'Jangha' was about 11.7g and the marketable yield was $19,013kg{\cdot}ha^{-1}$, 141% higher than 'Flamenco'. 'Jangha' is suitable for summer season cultivation as a high soluble solids contents cultivar, because it shows continuous flowering habit under long-day and high temperature conditions.
