| Este trabajo describe la evaluación del crecimiento del hongo ligninolítico Pleurotus ostreatus (cepas IE8 y CP50) sobre rastrojo de cebada suplementada con fuente de nitrógeno exógena (urea o sulfato de amonio) y humedades de 70 y 80 %; inicialmente se evaluó la velocidad de crecimiento radial (Vr) en cajas Petri y rastrojo de cebada. Las Vr más altas fueron 0.568 mm h-1 del testigo A (CP50, 80% de humedad, Medio con agua destilada) y 0.573 mm h-1 del tratamiento 6 (cepa IE8, 80% de humedad, Medio base). (Ver cuadro 5, pag. 23). Al adicionar una fuente de nitrógeno exógena las cepas no mejoran su Vr; sin embargo el 80% de humedad favoreció el Vr de ambas cepas. Con las condiciones antes mencionadas se eligió el hongo Pleurotus ostreatus (cepas... |

| Abstract: The objective of this work was to evaluate the inclusion of sunflower cake (SC) and the addition of enzymes in the ration of lightweight replacement pullets in the growth phase, as well as their effects on the variables feed consumption and conversion, productive performance, sexual maturity, egg quality at the beginning of the laying phase, and economic viability. Five hundred and forty pullets of the Hy-Line W-36 light line were used. The experimental design was completely randomized, in a 2×2+1 factorial arrangement, with two inclusion levels of SC (10 and 20%), with or without the addition of enzymes, and a control treatment. At the end of the growth phase (7 to 17 weeks age), 360 birds were transferred to the laying shed until their... |

| This study evaluated the digestibility of cottonseed meal with or without addition of enzymes (phytase and protease) for growing pigs. It was used 18 barrows, housed in metabolism cages, distributed in a completely randomized design, standardizing body weight (bw) with average of 25.8 ± 3.6 kg, with three treatments and six repetitions. The treatments consisted of a reference diet based on corn and soybean meal, the second treatment with replacement of 30% of the reference diet by cottonseed meal without enzymes, and the third with 30% of the reference diet replaced by cottonseed meal with added enzymes. Was determined the digestible protein, digestible energy, digestibility of dry matter, energy and protein. It was also registered the balance of nitrogen... |
