precision agriculture is continuously trying to address the sources and factors affecting the in-field variability and taking appropriate managerial decisions. one of the popular research focuses in the recent three decades has been on the development of new approaches to making yield variability maps. advancement in development of sensors and the importance of quality factor in high value crop...

A demonstration was conducted to examine the stored forage yield and stored forage quality of two different hay forage management systems. The forage management systems were a hay harvest only system or a complimentary hayround bale silage harvest system. The hay system harvested bermudagrass forage as hay during the summer when weather conditions allowed, the complimentary system harvested ber...

Field dry hay needs to be reduced from near 80% moisture to 20% or less to prevent spoilage during storage. Drying hay to safe baling moistures often takes several days. Sources of loss during forage harvest include mechanical losses such as mowing, conditioning, chopping, raking, packaging and handling as well as respiration and leaching. The general relationship between forage moisture concen...

The objective was to determine the effect of forage quality on apparent total tract digestibility and ruminal fermentation in cattle versus sheep. Five yearling English crossbred (Hereford × Angus) steers (440.4 ± 35.6 kg of initial BW) and 5 yearling whiteface (Rambouillet × Columbia × Debouillet) wethers (44.4 ± 4.6 kg of initial BW), each fitted with a ruminal cannula, were randomly assigned...

Oat (Avena sativa L.) traditionally has been a major crop for feed and forage in Turkey. Theobjective of this research was to study hay yield and quality of oat genotypes harvested at thelate milk stage. One hundred oat varieties of worldwide origin were compared in fieldexperiments in Samsun (northern Turkey) over two growing seasons (2007-2008 and 2008-2009).Significant differences between th...

The abundant growth of molds and thermophilic actinomycetes in stored hay decreases its quality and can be hazardous for the producer who inhales these contaminants when the moldy hay is fed in closed barns. These microbes are responsible for a respiratory disease called farmer's lung. Products, including bacterial cultures that can be inoculated in hay, are available to prevent hay deteriorati...

limited data exist about the production of extruded linseed as a feed ingredient in farm animal nutrition. the objective of this study was to produce and evaluate extruded linseed mixed with alfalfa hay, pistachio by-products, and sugar beet pulp or corn grain in different proportions of linseed: alfalfa hay: pistachio by-products at ratios of 70:15:15, 70:20:10, 70:10:20, and 80:10:10 for qual...

Forage quality of orchardgrass and timothy hays can be evaluated from both nutritional and marketing perspectives. From the nutritional perspective it is conditioned by the 1) nutrient concentration, 2) rate of voluntary intake, 3) digestibility and 4) partitioning of metabolized products within the animal. From the marketing perspective, hay destined for urban feed store and Pacific Rim market...

Thousands of hectares of timothy (Phleum pretense L.) grown in the Mid-Atlantic region are infected by cereal rust mite (Abacarus hysterix) that causes discoloration and curling of leaves, decreased nutritional quality, and substantial decreases in yield. A decline in production of timothy hay can lower income for hay producers and cause horse owners to search for alternative hays. Low alkaloid...
