“…Evaluating the effect from different slaughter weights on the carcass measurements, Issakowicz et al (2013) found 0.361kg/cm and 0.316kg/cm of CarcC, with the highest values for the greatest concentrate proportion, similar to the values obtained in this study. Overall, when correlating the in vivo body measurements with the measurements obtained on the carcass, we can verify that the correlations varied from medium to low, demonstrating that in vivo body measurements cannot be utilized as the sole parameter for prediction of the carcass measurements.…”

Quantitative and qualitative carcass characteristics of feedlot ewes subjected to increasing levels of concentrate in the diet [ ABSTRACTThe aim of this study was to evaluate the effect of increasing levels of concentrate on the quantitative and qualitative carcass characteristics of feedlot ewes. Twenty-four crossbred ewes were randomly distributed in four treatments: (1) diet with 20%; (2) 40%; (3) 60%; and (4) 80% of concentrate. Animals were slaughtered when those receiving the diet with 80% of concentrate reached adult weight, at around 50kg LW. The data were analyzed by means of variance and regression analyses and correlations. The levels of concentrate increased live weight at slaughter linearly. Height at the withers and rump presented medium to high correlation (0.86). The correlation of loin eye area measured on the carcass and by ultrasound examination was 0.81, whereas for back fat thickness it was 0.85. The increase in the use of concentrate in the diets promotes heavier carcasses with better yields and fat cover. Some measures obtained in vivo presented high correlation with those measured on the carcass. The use of ultrasound can be a way to predict the in vivo loin eye area. The use of concentrate improves the meat quality in variables' color and appearance.

“…Issakowicz et al (2013) Comparing the values, it can be observed that they are similar to those presented by the ewes of undefined breed in this study. Abdullah and Qudsieh (2008) observed that the amount of back fat rose gradually with increase in weight, and the carcass quality was also associated to slaughter body weight.…”

“…Despite these effects on ADFI, Mutsvangwa et al (1992), Vyas et al (2014a) did not observe a positive effect of S. cerevisae supplementation on growth or feed efficiency, which is in agreement with the current results. Accordingly to growth performance results, we did not find any effect on carcass characteristics, which is consistent with previous results in steers (Mir and Mir, 1994) and lambs (Issakowicz et al, 2013).…”

2017 I II IV AgradecimientosLlegar hasta este momento de finalización de la Tesis Doctoral ha sido una carrera de fondo que me ha acompañado a lo largo de mi maduración tanto a nivel profesional como personal, acompañándome en la mochila en numerosos momentos clave de mi vida.Todo empezó nada más presentar mi proyecto fin de carrera, cuando Carlos de Blas, (que de manera sutil, o quizá involuntaria, ha tenido la capacidad de llevarme a lo que soy ahora) comentó "dos artículos más y ya tienes la Tesis". Si bien en aquel momento me pareció una idea imposible, en el fondo se quedó plantada una semilla que comenzó a germinar el día en el que Pedro Medel me encargó realizar el estado del arte del proyecto de investigación que, con el soporte de COPESE, ha dado lugar a este trabajo.Recuerdo perfectamente aquel primer momento en el que visitamos la granja de terneras por primera vez y Javier Peinado dejó en mis manos el control de los ensayos.Llegar hasta el final de este proyecto hubiera sido imposible sin el apoyo tanto de mis compañeros de Imasde en aquellos momentos (Álvaro, Silvia, Jaime, Nacho y Fran), como de David del Pico, Marcos Nieto y Alfonso Fuentetaja de COPESE y, por supuesto, los profesores, investigadores y doctorandas del Departamento de Producción Animal I de la Universidad de León (Loli, Mariajo, Marisa, Eugenia, Silvia, Alfonso..) por su apoyo tanto en granja como en matadero, y especialmente en laboratorio.Quedan atrás muchos días de frío, me atrevería a decir casi siberiano, donde antes de empezar los ensayos algún día nos encontramos a Javier Rincón descongelando tuberías a soplete; aquellos momentos en los que una ternera despistada nos hacía correr los San Fermines por los pasillos, o los madrugones para poder realizar los controles en matadero. Son muchas las anécdotas que quedan atrás, y guardo con buen sabor de boca, un poco de nostalgia, pero especialmente satisfacción por todo lo vivido y aprendido, junto con el sincero agradecimiento a todos los que me han acompañado en este camino. En este proceso de aprendizaje, cabe sin duda la mención especial a mis directores, Pedro y Loli que, sin prisa pero sin pausa, me han impulsado a finalizar este trabajo.Los trabajos realizados en el marco de esta Tesis Doctoral han sido promovidos por Comercial Pecuaria Segoviana, SL (Coca, Segovia, Spain), y llevados a cabo en su granja experimental de terneros de cebo. Este proyecto ha sido financiado por el Ministerio de Industria Turismo y Comercio mediante el programa PROFIT (FIT060000200511) y el Centro para el Desarrollo Tecnológico Industrial (CDTI; IDI-20050617 RESUMENEl objetivo de esta Tesis ha sido estudiar la influencia de diferentes estrategias nutricionales sobre el control de la acidosis en terneros de cebo en un contexto experimental diseñado para representar el manejo nutricional predominante en España. Para ello, se llevaron a cabo tres ensayos experimentales que se describen a continuación.El primer experimento se diseñó para evaluar el efecto de la inclusión de malato, administra...

“…Similarly, Dobiri et al (2016) reported that all carcass traits were not affected by probiotic levels. Also, Issakowicz et al (2013) found that addition of live yeast to diet of Texel lambs reduced dressing percentage and they stated that this reduction may be due to the enlargement of the digestive tract as a result of increasing dry matter intake. The present results are in agreement with those of Whitley et al (2009) and Gadekar et al (2014) who found that supplementation of probiotic or lactateproducing bacteria did not influence cut weights in goats and sheep, respectively.…”
