Actividad de enzimas fibrolíticas y fermentación in vitro con paja de cebada y raicilla inoculadas con Pleurotus sapidus.
Provedor de dados: 32
Autores: Soto Sánchez, Alfonso.
El objetivo del presente trabajo fue conocer la acción enzimática del hongo basidiomiceto Pleurotus sapidus al actuar sobre los subproductos agroindustriales: Paja de cebada (PC), Raicilla (RC) y la Mezcla PC y RC 75:25 (M), además los cambios en su composición química que permitieran mejorar la digestibilidad de los subproductos usados en la alimentación de rumiantes. Se realizaron dos experimentos, el primero fue evaluar la actividad enzimática de lacasas, celulasas y xilanasas, a los 0, 8, 16 y 24 días de cultivo; las muestras obtenidas para cada tiempo se prensaron para obtener un extracto líquido (complejo enzimático) y posteriormente en el prensado residual se determinó la composición bromatológica de PC, RC y M en relación al valor inicial. Los...

Biosíntesis de lignina y comportamiento productivo en tres pastos de clima templado.
Provedor de dados: 32
Autores: Vargas Romero, Juan Manuel.
Tres especies de gramíneas de clima templado, el híbrido Festulolium y sus progenitores Festuca arundinacea y Lolium perenne, se evaluaron en invernadero para determinar el crecimiento, fracciones de la fibra y características anatómicas de cada especie. Además se extrajo el ADN de las tres gramíneas para realizar un análisis molecular y calcular correlaciones entre los marcadores y las variables analizadas. De acuerdo con los resultados, el Festulolium fue distinto a F. arundinacea y L. perenne en el número de láminas por tallo; respecto a la abundancia relativa de lignina, área de xilema y floema, el contenido fue similar entre Festulolium y L. perenne, mientras que los valores de densidad de tricomas en el haz fueron semejantes entre Festulolium y F....

It was evaluated intake, rumen and intestinal digestibility and passage and digestion rates in bovines fed diets constituted of corn silage, crushed sugar cane and given fresh, crushed sugar cane and given after 72 hours of storage, ensiled sugar cane with 1% of calcium oxide and with no treatment and a same concentrate fixed at 1% of body weight. All roughage was corrected to contain 10% of crude protein. It was used five rumen-fistulated bovine with average weight of 240 ± 15 kg, distributed in a 5 × 5 Latin square. Abomasum and total fecal collection and two rumen evacuations were carried out in the morning. Animals fed corn silage based diet presented greater rumen digestibility of the protein and intestinal digestibility of the ether extract, greater...

Apparent digestibility of diets with combinations of soybean hulls and coastcross (Cynodon sp.) hay offered to ram lambs
Provedor de dados: 63

Soybean hulls (SH) are an alternative fiber source that may be used to maintain neutral detergent fiber (NDF) concentration while increasing the energy concentration of ruminant diets. The objective of this experiment was to determine the effects of replacing coastcross (Cynodon sp.) hay NDF by SH NDF on the apparent digestibility of nutrients and nitrogen balance of Santa Inês ram lambs. Twenty-four animals (42.5 ± 3.6 kg of body weight and six months old) were placed in metabolism crates and assigned in a randomized complete block design defined by body weight (BW). Experimental diets provided a similar concentration of NDF (52%) and crude protein (15%). Hay NDF from a 70% roughage-based diet was replaced with SH NDF by 33%, 67%, and 100%, resulting in...

Nutrition value of silage from corn hybrids produced in Mato Grosso, State was evaluated. A randomized block design was used with 23 treatments (hybrids) and three replications. The study used hybrids from different seed companies. Fodder was stored in PVC pipes at a density of 600 kg of green mass m-³. The silos were opened 90 days after ensiling, and the following variables were studied: pH, dry matter (DM), ammoniacal nitrogen (N-NH3), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN) and minerals (Ca, P, K and Mg). Rates were estimated for dry matter intake (DMI), dry matter digestibility (DM), net energy for maintenance (NEm), gain (NEg) and lactation (EL). All the characteristics were...

Thirty-six experimental silos arranged in a completely randomized 4 x 3 factorial design were provided to evaluate the chemical changes of sunflower silage treated with soybean hulls, sunflower crushed and urea at 14, 21 and 28 days of ensilage. The additives were based on 5% natural matter, whereas control consisted of silage with 100% sunflower plant. OM, NDIP, and MM had average rates 911.2; 86.6 and 92.9 g kg-1 of dry matter respectively. The addition of soybean hulls and sunflower crushed increased DM rates after 28 and 21 days. Urea increased nitrogen fractions and the addition of soybean hulls increased total carbohydrate content of silage by 5.1%, whereas the addition of sunflower crushed decreased the same by 2.18%. NDF, ADF and hemicellulose...

The sowing season has great influence on the establishment of forage, as spreading seeds out of season tends to harm productivity. Consequently, the aim of this study was to evaluate sowing seasons, production and bromatological quality of Brachiaria forage species in Mineiros-GO. The experiment was held at IPAF/FIMES, in a typical Quartzarenic Neosol. The experimental treatments consisted of five sowing dates and five cultivars/species of forage grass (Brachiaria brizantha (Hochst) cv. Marandú, Brachiaria brizantha cv. Xaraés, Brachiaria hybrid cv. Mulato, Brachiaria decumbens Stapfe and Brachiaria ruziziensis). The experiment was designed in randomized blocks with sub-plots, with four replications, each block represented by a sowing date. Dry matter...

O trabalho foi realizado na Universidade Federal Rural da Amazônia com o objetivo de avaliar o consumo e digestibilidade aparente de ovinos alimentados com dietas contendo diferentes níveis de inclusão de torta de coco (25, 50 e 75%). Foram utilizados 12 ovinos, machos, da raça Santa Inês, com idade média de cinco meses e com peso médio de 19,5 kg, mantidos em gaiolas metabólicas individuais distribuídos em um delineamento inteiramente casualizado. Observou-se que o consumo de matéria seca decresceu com a inclusão de torta de coco, apresentando valores de 699; 405 e 373 g e 3,67; 2,15 e 2,00% do peso vivo para os níveis de 25, 50 e 75%, respectivamente. O mesmo comportamento foi observado para o consumo de proteína, entretanto não foram observadas...
