ABSTRACT
ABSTRACT: The objective of this study was the comparative analysis of selected attributes of nutritional and technological quality of pork from Naïma and DanBred gilts mated with P-76 boars. The research was carried on 50 pigs (25 in each group) reared under the same environmental conditions and slaughtered at about 115±5.0 kg. Both analyzed crossbreds populations were characterized by overall good nutritional and technological quality. However the loins from DanBred×P-76 compared with those from Naïma×P-76 had significantly greater glycogen and less lactate concentration in early post mortem period, higher pH at all measurement points (besides no statistical differences in pH measured 2 hours post mortem), lower thermal drip and drip loss measured 96 and 144 hours post mortem and lower lightness (except no differences measured 48 hours post mortem). Additionally loins from DanBred×P-76 contained more protein and less water. No statistical differences in IMF content between both analysed groups were noted (their average values were below 2%). Aforementioned may suggest that crossing both Naïma and DanBred hybrids with P-76 boars may not improve IMF content or increase marbling scores to the levels preferred for culinary purposes.
RESUMO: O objetivo deste estudo foi a análise comparativa de atributos selecionados de qualidade nutricional e tecnológica de suínos provenientes de marrãs Naïma e DanBred acasaladas com machos P-76. A pesquisa foi realizada em 50 suínos (25 em cada grupo) criados nas mesmas condições ambientais e abatidos com cerca de 115 ± 5,0 kg. Ambas as populações de mestiços analisadas foram caracterizadas por uma boa qualidade nutricional e tecnológica geral. No entanto, os lombos de DanBred × P-76 em comparação com os de Naïma × P-76 tinham glicogênio significativamente maior, e menor concentração de lactato no período post mortem inicial, pH mais alto em todos os pontos de medição (além de nenhuma diferença estatística no pH medido 2 horas post mortem), menor gotejamento térmico e perda de gotejamento medido 96 e 144 horas post mortem e menor leveza (exceto nenhuma diferença medida 48 horas post mortem). Além disso, os lombos de DanBred × P-76 continham mais proteína e menos água. Não foram observadas diferenças estatísticas no conteúdo do FMI entre os dois grupos analisados (seus valores médios estavam abaixo de 2%). O resumido acima pode sugerir que o cruzamento de híbridos Naïma e DanBred com machos P-76 pode não melhorar o conteúdo de IMF ou aumentar as pontuações de marmoreio para os níveis preferidos para fins culinários.
ABSTRACT
Objective:To analyze the overall situation and existing problems of the scientific and technological innovation capacity of hospitals in Shandong Province, propose strategies for the construction of first-class medical disciplines in hospitals, promote the transformation of medical science and technology achievements into clinical application, and provide a reference basis for building a highland of health scientific and technological innovation.Methods:Science and Technology Evaluation Metrics (STEM) data of hospitals in Shandong Province in 2020 were obtained by network research method, and the scientific and technological innovation capacity and sustainability of hospitals and disciplines were analyzed by statistical description method, assignment method, and NetDraw visualization tool.Results:The number of national top 100 hospitals and disciplines in Shandong Province ranks seventh and sixth in China, respectively. Only three hospitals in Shandong Province are among the national top 50, covering 80.6% of provincial top-ranked disciplines, while 41.6% of the national top 100 disciplines in Shandong Province are ranked after the top 50 in their respective discipline lists. The hospital scientific and technological innovation capacity of Shandong Province is at the middle-upper level with few and uneven distributions of first-class hospitals and disciplines, leading to a relatively weak overall science and technology impact.Conclusions:Given the current situation in Shandong Province, it is suggested that hospitals should take STEM as a guide to strengthen the construction of scientific research environments, vigorously develop clinical research, continuous strengthen discipline construction, and emphasize scientific innovative talent training and research integrity education, providing a science and technology strategic support for the acceleration of the medical scientific and technologic innovation and the promotion of high-level innovative province construction.
