Performance profiling of Standardbred racehorses by means of Treadmill Exercise Testing
Get PDFTreadmill exercise testing can be performed on a horse to evaluate the level of fitness with the aim of predicting performance (Franklin and Allen, 2014). The speed at 2 mmol/L of blood lactate (VLA2), the speed at 4 mmol/L (VLA4) and the speed at 200 bpm of heart rate (V200) are indices that have been related to performance (Coroucé et al., 2002). Aim of the present work is to analyze these parameters in a population of high performance Standarbred racehorses.
Six healthy and at the same level of training Standardbred racehorses (average age 3,3±2,0 y.o.) underwent an incremental exercise test (Zucca et al., 2003) on a high speed treadmill (Sӓto I, SATO, Sweden). During the test heart rate (HR) was monitored with a heart rate meter (Polar horsetrainer, Polar, Finland). Venous blood was collected with the aid of a 14G teflon venous catheter placed in the jugular vein. Plasma lactate was measured with enzymatic colorimetric method lactate dry-fast kit for automatic system (Cobas Mira Classic, Roche, Switzerland). Data were analyzed with a dedicated software (Lactate Express, Mesics, Germany) and VLA2, VLA4 and V200 were calculated and statistically compared by T-student test for paired sample (Prism, GraphPad, USA). Statistical significance was set at p<0,05.
Average VLA2 was 8.3±0.5 m/s, average VLA4 was 9.2±0.4 m/s, average V200 was 8.1±0.9. There was a significant difference between VLA4 and V200 (Fig. 1). No difference was observed between VLA2 and V200
V200 is often reported to be close to VLA4, and considered as correspondent to the onset of blood lactate accumulation (Coroucé et al, 2002). According to our results, it may be argued that V200 is a measure that does not fit with the lactate threshold.
These data could be used as control for further studies on racehorses with poor performance syndrome
Geometric morphometrics and internal anatomy in sea bass shape analysis (Dicentrarchus labrax L., Moronidae)
No full textThe effects of different conditions of larval and postlarval rearing on the external morphology and internal anatomical characters were studied in juvenile and adult specimens of Dicentrarchus labrax L. (Teleostea, Moronidae) in order to assess the potential of a combined methodology in the assessment of finfish quality. Differences in the external morphology between two samples were analysed before their introduction into floating cages and after 15 months of common rearing. Shape differences were studied with geometric morphometrics. Significant differences in shape were found in juveniles. In adults, at the end of the common rearing, differences were smaller but still significant. The importance of larval rearing conditions in determining sea bass juvenile and adult shape is evident as well as a phenomenon of morphological resilience. On the same specimens, internal anatomical data were collected from X-rays. In this way, it was possible to correlate fish shape with internal anatomical data. Characteristic shapes were associated with particular cadres of internal anatomical anomalies, such as head shape and anomalies in the cephalic region, a bent body shape and lordosis of the haemal and prehaemal regions, the shape of the caudal region and lordosis of the caudal vertebral axis. Streamlined wild-like profiles were associated with light anomaly cadres. The use of the combined approach proposed is, thus, recommended in the description and quantification of shape features and particularly in the context of fish quality assessment.

Imprese leader e territorio: il ruolo della grande distribuzione commerciale nello sviluppo imprenditoriale del Made in Italy
No full textObiettivo del paper è approfondire il ruolo delle imprese leader quali attori critici dello sviluppo dei sistemi locali con particolare riguardo alle imprese della distribuzione commerciale. Viene anzitutto proposta una rilettura delle ricerche in tema di imprese leader e dei processi di sviluppo imprenditoriale locale “indotti” dall’azione di una media-grande impresa evidenziando alcuni elementi di novità che recentemente emergerebbero nelle relazioni con il territorio. L’attenzione si concentra poi sul nuovo ruolo che taluni big retailers possono svolgere nei sistemi produttivi locali rispetto alle tradizionali imprese manifatturiere leader. In particolare, si mettono in evidenza le differenze di ruolo tra i big retailer aventi un’imprenditorialità endogena (quale Coop in Italia) e big manufacturing companies proiettate su scenari globali (e, quindi, più soggette a dinamiche di delocalizzazione e caratterizzate da un minore radicamento economico sul territorio).
Rispetto alla tradizionale approccio che sottolinea i rischi per le PMI italiane dell’emergere di nuove logiche distributive, si sottolineano anche le opportunità connesse all’affermazione della GDO per lo sviluppo delle imprese partner. Viene infine esaminata l’esperienza di Coop Centro Italia quale generatore di valore per la rete di fornitori operanti nel territorio. L’analisi fornisce un quadro quantitativo e qualitativo nel rapporto con le diverse filiere di fornitura di beni e servizi, mostrando la capacità di Coop Centro Italia di contribuire – in via diretta o indiretta – ad indurre una crescita organizzativa, occupazionale, manageriale ed economica di molte piccole imprese locali. Il caso esaminato permette di evidenziare un efficace meccanismo generatore di “imprenditorialità esterna” (nel senso di capacità di attivazione di relazioni “virtuose” impresa-territorio)
