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) + ...

Worldwide there are between 10 and 11 million hectares of coconuts. With the marked fluctuations and long term decline in copra and coconut oil prices the integration of livestock and coconuts is economically increasingly attractive. Traditionally used for weed control in plantations so that coconuts could be located, cattle (and sheep and goats) are increasingly seen as important parts of the ...

There is a shortage of information about the ryegrass crop (Lolium multiflorum Lam.), especially regarding suitable sowing rate. Thus, present work aimed to determine most adequate rate for tetraploid cultivars. A population was sown at different densities: 150, 300, 600, 900, 1200, 1500, 1800 seeds/m². The number plants per m², percentage soil cover, leaf yield and green dry forage were evalua...

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Cultivar development in alfalfa relies on heterosis, that has been mainly exploited by intercrossing selected clones from diverse gemplasm sources; an alternative way was proposed, based on developing double cross cultivars obtained by crossing clones selected for self-sterility, propagated by somatic seed. A differen...

Napier grass (Pennisetum purpureum Schumach.) is a fast-growing perennial grass native to Sub-Saharan Africa that is widely grown across the tropical and subtropical regions of the world. It is a multipurpose forage crop, primarily used to feed cattle in cut and carry feeding systems. Characterization and diversity studies on a small collection of Napier grasses have identified a moderate level...

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...
