ABSTRACT An evaluation of the effects of monensin and calcium propionate on the in vitro kinetics of gas production, digestibility, carbon dioxide, and minor gas production on different days was performed using the ruminal fluid from eight Suffolk lamb donors, after receiving additives for 1, 10, and 20 days. Treatments consisted of a control ration of 40% grain; 30 mg/kg of monensin in a diet with 40% grain; 10 g/kg calcium propionate in a diet with 30% grain; and the combination of both additives in a diet with 30% grain. The gas production was measured up to 72 h of incubation and all incubation procedures were repeated three times on days 1, 10, and 20. On incubation day 20, the volume and production of methane and minor gases were measured. There was...

Evaluación de envases de polietilentereftalato como fuente de fibra en dietas para rumiantes

Esta investigación tuvo como objetivo evaluar el potencial de envases de polietilentereftalato (PET) molido como fuente de fibra en dietas para ovinos en engorda, en sustitución de rastrojo de maíz. El estudio tuvo una duración de 60 d con 10 d de adaptación. Se utilizaron 30 borregos machos con un peso vivo promedio de 24.87 ± 1.7 kg alojados en jaulas individuales. Los tratamientos (T) incluyeron tres niveles de envases de PET molido en la dieta (en base a MS): T1 = 0 %, T2 = 10 % y T3 = 20 %. Las variables medidas fueron: ganancia diaria de peso (GDP), consumo de materia seca (CMS), digestibilidad in vivo de materia seca (DIVMS), conversión alimenticia (CA), PET en heces (PETh) y digestibilidad in vivo de materia seca del PET (DIVMSPET). En el líquido...

It was aimed in this work to evaluate bacterial strains tolerant to products based on propolis (LLOS) through the isolation, morphological and biochemical characterization techniques in diets with roughage:concentrate ratio 100:0 and 50:50. For roughage diets, the products LLOSC1 and LLOSB3 were evaluated, and for 50:50% diets, the products LLOSC1, LLOSD1, LLOSA2, and LLOSC3, which differed in alcoholic concentrations (1, 2 and 3) and propolis (A, B, C and D) concentrations. The ruminal liquid was anaerobically incubated at 39°C for 6 days in medium containing LLOS. After isolation, the strains were submitted to Gram staining and the bacterial growth was monitored by photospectrometer. It was evaluated the strain growth in the presence of the following...

Using sorghum silage, the effect of roughage/concentrate ratios was evaluated on nutrient intake, digestibility, ruminal parameters and methane production by beef cattle. Three treatments (0, 30 and 60% of concentrate in DM of the diet) were distributed in three Latin squares, with nine animals and three periods. Dry matter intake increased as the grain concentration in diet increased; pH showed opposite behavior. Methane emissions were lower for animals fed the diet exclusively with sorghum silage as compared with those fed 30% of concentrate, but was similar to that of animals receiving 60% of concentrate. Losses of ingested gross energy as methane were reduced by 33% when grain concentration was increased in the diet. Concentrations of propionic and...

The determination of protein fraction and rumen fermentation characteristics of pearl millet genotypes is important, since generate information about food nutritional value and also guide the breeding programs of genotypes to be used in diets of ruminants. The objective of this research was to determine the digestion rates of protein fractions, dry matter degradability and in vitro dry matter digestibility of silages from pearl millet genotypes produced at different cutting ages. The experiment was carried out on the Agronomy campus of theRioVerdeUniversityand on the Rio Verde campus of Goiano Federal Institute. The experimental design was randomized blocks with four replications in a 5 x 3 factorial arrangement, with five genotypes of millet: ARD 500, ADR...

ABSTRACT - The objective of this study was to evaluate the effect of replacing wheat bran by spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on intake and nutrient digestibility and ruminal parameters of sheep. Five sheep (Santa Inês; average initial weight of 34.0±3.6 kg) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. The maximum dry matter (DM; 1414 g d−1), digestible organic matter (658 g d−1), and neutral detergent fiber corrected for ash and protein (NDFap; 425 g d−1) intakes were estimated by replacing 80.2, 89.9, and 50.5% of wheat bran. Dry matter and crude protein digestibility increased by 0.60 and 0.85 g kg-1 of DM. With the replacement of 57.1 and 62.2% of wheat bran, a maximum rate...

Uso de levaduras y fumarato para disminuir la metanogénesis en la fermentación de alfalfa.

Báez Pérez, José Luis.

Se realizaron tres experimentos en biorreactores acoplados a trampas de gas para evaluar el efecto de Saccharomyces cerevisiae y fumarato de sodio en la fermentación in vitro de alfalfa. En el primero se evaluó la fermentación de alfalfa en medio de cultivo glucosa, celobiosa, almidón y fluido ruminal (GCAFR) usando trampas de gas con agua, solución salina ácida y solución de NaOH. Se midió producción de biogás, CH4, CO2, pH y bacterias totales (BT). El diseño experimental fue completamente al zar con arreglo factorial 2 x 3, y tres repeticiones por tratamiento. En el segundo experimento se evaluó el efecto de Yea sacc®, Procreatin 7® y Diamond V XP® en la fermentación in vitro de alfalfa. Se midió producción de CH4, ácidos grasos volátiles (AGV),...
