“…After the first medical applications, this ultrasound technique was immediately recognized as a potential tool for animal science, as shown by the work published in the late 1950s on animal carcass evaluation (Stouffer, 2004). These publications reported research results showing the feasibility of using ultrasound to evaluate carcass composition in live cattle (Temple et al ., 1956), swine (Claus, 1957;Dumont, 1957;Hazel and Kline, 1959) and sheep (Campbell et al ., 1959).…”

Abstract:In this chapter the use of real-time ultrasonography to predict in vivo carcass composition and meat traits will be reviewed. The chapter begins by discussing background and principles of ultrasound. Then aspects affecting the suitability of realtime ultrasonography and image analysis for predicting carcass composition and meat traits of meat producing species and fish will be presented. This chapter also provides an overview of the present and future trends in the application of real-time ultrasonography in the meat industry.

“…There are two issues that have arisen in the measurement of fat using ultrasound. First, the effect of the transducer's protective layer on the accuracy of the ultrasonic velocity measurement using A-mode analysis, and secondly, B-mode image positioning accuracy due to the application of a predetermined ultrasonic velocity for B-mode imaging [8]. In this paper, we present a preliminary study to increase the positioning accuracy of B-mode images using adapted time of flight measured by A-mode analysis.…”

Abstract. This research attempted to measure chicken intramuscular fat content using improved ultrasound B-mode images and image segmentation. Adapted Bmode imaging is proposed to increase the positioning accuracy of B-mode images with the objective to correct the phase error due to the use of predetermined ultrasonic velocity in conventional B-mode imaging. The predetermined velocity is replaced by actual velocity measured using A-mode imaging. The positioning accuracy of adapted and conventional B-mode imaging was validated using 144 chicken samples. The adapted B-mode image had better positioning accuracy compared to a conventional B-mode image since the method used was able to detect the thickness of the chicken sample with a lower mean difference (0.036±0.034mm vs. 0.113±0.010). Both methods were then applied for measurement of intramuscular fat content. The histogram mean and the percentage of fat pixels were the B-mode image characteristics that were extracted and their correlation with the fat content, measured using the Soxhlet method, was analyzed. The properties of the adapted B-mode images correlated better with the Soxhlet-measured fat content compared to the properties of the conventional B-mode images as reflected in the correlation coefficient, r, for the histogram mean (0.357 vs. 0.129) and the percentage of fat pixels (0.406 vs. 0.289). The results indicate the potential of using ultrasound adapted B-mode imaging to measure chicken intramuscular fat.

“…As a consequence of this, it is important to evaluate the growth for backfat (BF) and loin muscle (LT) in each genotype in order to ensure that dietary treatment does not modify their growth characteristics. Ultrasonic technologies have been used since 1950, among other systems, for evaluating BF and LT depth in live animals (Wild, 1950;Hazel & Kline, 1959) and are still nowadays used by many pig producers to measure these traits.…”

The effect of a high monounsaturated fat diet on body weight, backfat and loin muscle growth in high and medium-lean pig genotypes

The objective of this study was to evaluate whether the use of a diet rich in oleic acid could have an effect on daily weight gain, backfat and loin muscle (Longissimus thoracis) depth. One hundred and ninety-two barrows and gilts, from two genotypes were fed a grain and soy diet (CONTROL with 28% C18:1) or a similar diet enriched with oleic acid (HO with 43% C18:1, Greedy-Grass OLIVA ® ). The pigs were housed in 16 pens in groups of 12 according to their sex, diet and genotype. From 75 days of age every three weeks, the pigs were weighed and the backfat and loin muscle depth were ultrasonically recorded (PIGLOG ® ). The inclusion of the dietary fat had no significant effect on the growth variables nor on the backfat and loin muscle depth measurements taken. However, the barrows resulted in higher live weight and backfat compared to the gilts at the end of the trial. Conversely, the gilts showed higher loin depth. Moreover, York-sired pigs were heavier than Pietrain-sired pigs during the whole trial and showed higher backfat at the last two measurements. Pietrain-sired pigs had higher loin muscle depth at the last measurements. The results of the present study suggest that the addition of a dietary fat into diets aiming at modifying the meat fatty acid profile has no detrimental effects on performance variables, or on backfat and loin muscle growth and thus, no negative economic impact for producers.Additional key words: backfat depth; loin muscle depth; monounsaturated fatty acids; sex. ResumenEfecto de una dieta rica en ácidos grasos monoinsaturados sobre el peso vivo, el espesor de grasa dorsal y la profundidad de lomo en cerdos de alto y medio crecimiento magro El objetivo de este estudio consistió en evaluar si administrar una dieta rica en ácido oleico en cerdos de engorde ejercía algún efecto sobre la ganancia de peso, el espesor de grasa dorsal y la profundidad del músculo Longissimus thoracis. Ciento noventa y dos machos castrados y hembras de los genotipos (Landrace*Large White)*Pietrain y (Landrace*Large White)*York recibieron una dieta de cereales y soja (CONTROL con 28% C18:1) o una dieta similar rica en ácido oleico (HO con 43% C18:1, Greedy-Grass OLIVA ® ). Los cerdos se alojaron en 16 corrales en grupos de 12, según su dieta, sexo y genotipo. A partir de los 75 días de vida, y a continuación cada tres semanas, los animales se pesaron y se midió mediante ultrasonidos (PIGLOG ® ) el espesor de grasa dorsal y la profundidad de lomo. No se detectaron diferencias en la ganancia media diaria ni en el espesor de grasa dorsal y lomo entre los cerdos alimentados con dieta HO y dieta CONTROL. En cambio, los machos castrados presentaron un mayor peso vivo y un mayor espesor de grasa dorsal que las hembras. Estas, en cambio presentaron una mayor profundidad de lomo. Los cerdos cruzados con York fueron más pesados durante toda la prueba y presentaron un mayor espesor de grasa dorsal que los cruzados con Pietrain. Los animales del genotipo Pietrain presentaron una mayor profundidad de lomo durante las ...
