Peroxidases (EC 1.1 1.1.7; donor: hydrogen-peroxide oxidoreductase) have been implicated in numerous physiological processes of potential importance in plant-pathogen interactions, including lignification (Walter, 1992), crosslinking of cell-wall components (Bradley et al., 1992), wound healing (Sherf et al., 1993), auxin oxidation (Grambow and Langenbeck-Schwich, 1979), and systemic acquired r...

The objectives of the current study were to determine the amounts of aboveand below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fal...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

Forage is included in beef cattle growing or finishing diets for several reasons. Nutritionally, forage provides protein, vitamins and minerals. When included as a minor component of high grain finishing diets, forage may increase feed intake and reduce nutritional disorders due to increased salivation, rumination and passage rate. Manipulating dietary moisture content through inclusion of dry ...

The objective of this study was to examine the effect of different forage and supplement combinations on forage and supplement intake and ruminal parameters in steers. Six ruminally fistulated steers were assigned to 1 of 4 treatments during 4 different data collection periods. Treatments were 1) Hay +wet brewers grains (WBG); 2) Hay +dried distillers grains (DDG); 3) round bale silage (RBS) + ...

This study was carried out to compare agro-morphological traits and nutritive value of 25 tall fescue (Festuca arundinacea) ecotypes grown in Tehran, Iran. The experiments were carried out in a split plot design during 2016-2018 growing seasons. The results showed that there was a significant genetic variation in existing germplasm. The highest heritability was related to dry forage yi...

A elaboração e utilização de minissilo polietileno poderia contribuir para as análises silagens experimentais, por utilizar material já empregado a produção comercialização silagem ensacada, o que permitiria condições fermentação mais próximas àquelas observados no campo. Objetivou-se neste estudo, avaliar os perfis fermentativos das capim elefante em minissilos tubo policrometo vinila (PVC) ou...

The aim of this study was to determine the effect of winter wheat (Triticum aestivum L.) forage growth stage, forage allowance, time of day, and commercial condensed tannins (CT) on steer bloat dynamics and in vitro ruminal gas production. Twenty-six crossbreed steers (Angus x Hereford x Salers; average initial BW = 194 +/- 26 kg) were used. Wheat forage allowances were either 18 kg (high forag...

Regenerated forests now compose over half of the world's tropical forest cover and are increasingly important as providers of ecosystem services, freshwater, and biodiversity conservation. Much of the value and functionality of regenerating forests depends on the plant diversity they contain. Tropical forest diversity is strongly shaped by mutualistic interactions between plants and fruit-eatin...
