Forage plant breeding has been largely based on phenotypic selection following sexual recombination of natural genetic variation found between and within ecotypes. Advances in plant genetic manipulation over the last 15 years have provided convincing evidence that these powerful technologies can complement and enhance plant breeding programs. Significant progress in the establishment of the met...

Two explanations exist for the evolutionary origin of grouping in primary consumers: reduction of individual predation risk and resource-mediated aggregation. While several studies have assessed relationships between aggregation and predation risk, few studies have examined the circumstances under which resource-mediated aggregation can lead to stable group formation. Using a model, we examined...

This research was conducted to identify the limitative factors of forage productionsuitability in order to achieve the sustainable exploitation of natural ecosystems in AliabadWatershed in Lorestan in 2013. The field measurements have been done through cutting andweighing method to estimate the forage amount, four-factor method to determine the rangecondition, trend scale to specify the orienta...

In large-type goats that were fed on dry forage twice daily, dry forage intake was markedly suppressed after 40 min of feeding had elapsed. The objective of this study was to determine whether or not marked decreases in dry forage intake after 40 min of feeding are mainly caused by the two factors, that is, ruminal distension and increased plasma osmolality induced thirst produced by dry forage...

In large-type goats that were fed on dry forage twice daily, dry forage intake was markedly suppressed after 40 min of feeding had elapsed. The objective of this study was to clarify whether or not increases in plasma osmolality and subsequent thirst sensations produced by dry forage feeding suppress dry forage intake. Eight large-type male esophagealand ruminal-fistulated goats (crossbred Japa...

dairy herd. The quality of these forages greatly impacts profitability and performance, especially of the milking herd. Because of limited land base, labor, or personal preference, farmers may decide to purchase part or all of their herd’s forage needs. In other parts of the United States, corn silage and other chopped forages are sold and oftentimes delivered to the farm as needed. In Kentucky...

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...

spp.) showed that forage DM intake was positively correlated with N fertilization rate. Fertilization may also Because native, shortgrass prairies are not typically fertilized and increase forage preference by livestock. Cook and Jeffotherwise extensively managed, little information is available on their response to nitrogen (N) fertilization. An experiment was conducted eries (1963) showed tha...

1 Foraging by geese has led to vegetation loss in salt marshes along the Hudson Bay coast and lesser snow geese are increasingly grazing inland freshwater marshes. We determined whether different nutrients limit the growth of forage plants in the two habitats, and whether these differences affect the nutritional quality of vegetation available to geese at La Pérouse Bay, Manitoba. 2 Results fro...

Arid climates have unpredictable precipitation patterns, and wildlife managers often provide supplemental water to help desert ungulates endure the hottest, driest periods. When surface water is unavailable, the only source of water for ungulates comes from the forage they consume, and they must make resourceful foraging decisions to meet their requirements. We compared two desert bighorn sheep...
