Composición bromatológica de la carne de conejos suplementados con mataratón y cachaza de palma aceitera / Bromatological composition of rabbit meat supplemented with mataraton and palm-press fiber

Objetivo. Evaluar comparativamente el efecto de la suplementación del alimento balanceado comercial (ABC) con follaje de mataratón (Gliricidia sepium) y cachaza de palma aceitera (Elaeis guineensis) en la composición bromatológica de la carne de conejo. Materiales y métodos. Las muestras de carne estudiadas en el presente trabajo, provienen de una investigación previa con un diseño experimental de bloques al azar con tres tratamientos (dietas) y tres repeticiones (bloques) con muestreo de tres réplicas por repetición, donde se utilizaron 27 conejos machos mestizos durante el período postdestete divididos en tres tratamientos: uno control (T0), alimentados sólo con ABC, y dos suplementados con mataratón y cachaza de palma aceitera en proporciones de 30 y 10% (T1), y 10 y 30% (T2), respectivamente, a manera de comparar el efecto de las dietas en el valor nutricional. Resultados. Las muestras de carne provenientes de los diferentes animales en tratamiento, se evaluaron encontrando que la suplementación no afectó significativamente la composición bromatológica (p>0.05) para el contenido de humedad (70.77 a 72.42%), proteínas (19.08 a 20.34%), cenizas (1.53 a 1.68%) y lípidos (6.48 a 7.23%); indicando que indistintamente de la dieta empleada, suplementando el ABC con mataratón/fibra de palma o no, las carnes de conejo obtenidas son nutricionalmente idénticas como alimento. Conclusiones. Con base en los resultados, se sugiere que el follaje de mataratón y la fibra de palma aceitera podrían constituir una alternativa como recursos agronómicos tropicales en la producción de carne de conejo para el consumo humano.

Objective. Comparatively evaluate the effect of supplementing commercial balanced feed (BCF) withmataratón (Gliricidia sepium) foliage and palm-press fiber (Elaeis guineensis) on the bromatologiccomposition of rabbit meat. Materials and methods. The meat samples studied came from a previousresearch which used a randomized block design with three treatments (diets) and three replications(blocks) with three replays by replication sampling where 27 hybrid male rabbits during their postweaning growth period, were used in three treatments: control (T0), animals supplied only with BCF,and two supplemented treatments with mataratón foliage and palm-press fiber at 30 and 10% (T1), and10 and 30% (T2) proportions, respectively, in order to compare the nutritional value of the differentdiets. Results. The evaluation of meat samples from different animals in the treatments showed thatthe bromatological composition of the meat was not significantly affected by the supplementation(p>0.05) for humidity (70.77 to 72.42%), protein (19.08 to 20.34%), ash (1.53 to 1.68%), andlipid (6.48 to 7.23%) contents; indicating that, regardless of the diet used, supplementing CBF withmataraton/palm-press fiber or not, the rabbit meats obtained are nutritionally identical. Conclusions.Based on the results, it is suggested that the foliage of mataraton and palm-press fiber may be analternative, as a tropical agronomic resource, in the rabbit meat production for human consumption.

Physicochemical characterization of acetaminophen-ethylcellulose solid dispersion

In this study, ethylcellulose was evaluated as a carrier for the preparation of sustained release of acetaminophen via solid dispersion technique. Physical mixture at the same level of acetaminophen and ethylcellulose was prepared. Differential scanning calorimetry and scanning electron microscope were used to characterize the physical properties of the various systems and to determine if there is possible interaction between acetaminophen and ethylcellulose
