SUMMARY:

The complete extruded diet is a concentrated feed that in its composition has the amount of volume for equine consumption, therefore, it is necessary as the only minimum. The evaluation percentage was evaluated a summary of the nutrients of the extruded complete diet in eventing horses, evaluation of live weight, body and fat score of horses during a consumption cycle of extruded complete feed. The research was carried out in the Laboratório de Avaliação do Desempenho de Equinos - LADEq/UFRRJ, located at the Escola de Equitação do Exército (EsEqEx)and at the Laboratório de Pesquisas em Saúde Equina – EQUILAB - UFRRJ. The project was approved by the Ethics Committee on the Use of Animals (CEUA) under n° 6062121118. Thirteen horses were used, between males and females, with live weight (LW) of 492kg aged between eight and fifteen years of the Brasileiro de Hipismo breed. The experiment was done entirely in design, treatments were done by three diets. The control diet consisted of pelleted ration and coastcross hay (n = 5). The second diet was the complete extruded one (FORRAGE HORSE ENERGY - NUTRATTA) (n =4), indicated for athletic horses in activity. The third diet was a complete extruded diet plus coastcross hay, through the hay bag (EQUILIBRE) as environmental enrichment (n = 4). Daily physical activity training animals in the CCE modality for nine months. Consume heavy weight diets after fifteen body consumption estimates, with % of BW. Live weight (LW); body score (BE) and body percentage due to fat throughout the training training cycle. Voluntary dry matter intake and diet intake rate (g MS/Min) are determined over 5 days at 5:00 am and 6:00 pm, totaling 10 observations/animal. The fecal physicochemical evaluation was performed using the variables: syllable weights (g), fecal density (g/mL), total DM (%), pH. Digestibility (CD) was calculated using the external TiO₂ indicator, at a concentration of 0.01456 g/kg external. The NDFi internal indicator was raised 144 hours after food samples incubation and in vitro collection. There was no significant difference between the diets regarding BW, EC and %BF that remained stable during training. The significantly lower consumption rate for the complete extruded diet (Nutratta) with a DM/Min value of 19.80 when the Control and Nutra Enrichment diets were tested with means of 59.32 g DM/Min and 48.92 g of MS/Min, respectively. The total DM content was significantly lower for the Control diet with values of 24.95% when compared to other diets with averages of 30.25% and 76%. The other physical-chemical characteristics did not present significant differences. TiO2 as an internal indicator showed higher CD values when compared to the internal indicator FDni. The Nutratta diet showed higher CD values compared to other diets, except for CDCEl. The complete non-diurnal diet of the EsEqEx routine and maintained as conditions foreseen for the equine athletes during the training cycle.
