Value Of Saltbush Questioned, Brian Warren, Tess Casson, Ed Barrett-Lennard

Journal of the Department of Agriculture, Western Australia, Series 4

Over the last 20 years the Department of Agriculture has focused on finding plant species that can grow on salt/and to produce sheep feed, and on techniques for establishing plantations of saltbushes. Some research has been in response to farmer reports of success in using revegetated salt/and to provide autumn forage, while other work has resulted from the apparent importance of saltbushes in rangeland areas.

Objective measurements of wool production have been taken only recently. Three years research at Katanning indicates that while saltbush material is selected and eaten by sheep, its value for wool production is not high. It …

Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt

Natural resources published reports

Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

Addition Of Cellulolytic Clostridia To The Bovine Rumen And Pig Intestinal Tract, Vincent H. Varel, J.T. Yen, Kelly K. Kreikmeier

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Studies were conducted to determine whether intestinal cellulolytic bacteria could be introduced into the bovine rumen or pig large intestine. In the first study, the ruminal fluid of three cows was evacuated and replaced with 20 liters of buffer and 6 liters of the ruminal or swine cellulolytic organism Clostridium longisporum or Clostridium herbivorans, respectively. The introduced organisms were the predominant cellulolytic bacterium in the fluid (>107 cells ml21) at 0 h. C. longisporum was still the predominant cellulolytic organism after 5 h, at 0.55 3 107 cells ml21; however, after 24 h the count of C. longisporum …

How To Make Your Alfalfa More Profitable, Clive Holland

Kentucky Alfalfa and Stored Forage Conference

As a perennial plant, alfalfa can be expected to continue to live and produce for an indefinite period of time. Why then do stands need to be replanted every few years? Is modern seed available today, weakened and unable to live up to the perennial label? What about yield? How does your stand measure up? Are you barely making the state average, or struggling to even meet this modest yield level?

The first harvest each spring can produce over 40% of the yield in a single growing season. Why is a stand slower growing in the spring than you would …

Role Of Alfalfa In Animal Diets, Jennifer L. Garrett

Kentucky Alfalfa and Stored Forage Conference

Alfalfa forage use has increased in all classes of livestock - dairy, beef, horses, sheep, and swine - during the last 40 years. The highest utilization of alfalfa by livestock is found in dairy cattle diets. Additionally, the use of alfalfa as a grazing crop has also undergone a considerable increase with the use of new grazing management techniques and the development of new grazing varieties.

Alfalfa's strength as a forage crop is its high nutritional value. Alfalfa is higher in protein, minerals, and net energy than grasses and small grains. High quality alfalfa also helps to promote intake, especially …

Alfalfa As A Grazing Crop: Progress Continues, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

This makes the third consecutive year that I have talked about "Alfalfa as a Grazing Crop". At our XIII Kentucky Alfalfa, I, along with five other speakers, discussed several aspects of grazing alfalfa and all agreed that the concept had tremendous potential.

This past year I reviewed some of the discussion of our XIII Conference and shared some of the activities going on in research and educational programs throughout the region. In addition, I announced the date for a National Alfalfa Grazing Conference to be held in Nashville, Tennessee. The Conference was held July 29 and was a big success. …

Abundance, Growth Rate And Parasitism Of Brevicoryne Brassicae And Myzus Persicae (Homoptera: Aphididae) On Broccoli Grown In Living Mulches, Michael J. Costello, Miguel A. Altieri

Horticulture and Crop Science

In 1990 and 1991, populations of the cabbage aphid, Brevicoryne brassicae, and the green peach aphid, Myzus persicae, were monitored on broccoli interplanted with three leguminous cover crops (the living mulches) and compared with broccoli without cover crop (clean cultivation). The cover crops used were white clover (Trifolium repens L.), strawberry clover (Trifolium fragiferum L.) and a mixture of birdsfoot trefoil (Lotus corniculatus L.) and red clover (Trifolium praetense L.). Fertilizer was applied as compost or synthetic fertilizer crossed with cropping system regime. Brevicoryne brassicae can reach pest status in Brassica cropping systems, whereas …

Ruminal Degradation Of Switchgrass, Big Bluestem, And Smooth Bromegrass Leaf Proteins, Daren D. Redfearn, Lowell E. Moser, Steven S. Waller, Terry J. Klopfenstein

Department of Agronomy and Horticulture: Faculty Publications

Two in situ protein disappearance experiments were conducted to determine disappearance rates of leaf protein fractions and characterize individual leaf protein fractions that escaped ruminal degradation. Fresh leaf blades of two warm-season grasses, switchgrass (Panicum uirgatum L. 1 and big bluestem (Andropogon gerardii Vitman), and one cool-season grass, smooth bromegrass (Bromus inermis Leyss.), were included in Exp. 1. Only warm season grasses were used in Exp. 2. Leaves were harvested from greenhouse-grown plants, placed in polyester bags, and incubated up to 48 h in situ in three ruminally fistulated steers fed diets of warm season grass hay. …

The Royal Catchfly (Silene Regia; Caryophyllaceae) In Indiana, Rebecca W. Dolan

Scholarship and Professional Work - LAS

Botanist Thomas Nuttall called the royal catchfly, Silene regia, "one of the most splendid species in existence." This red-flowered, hummingbird-pollinated member of the Caryophyllaceae is a perennial herb of prairies and glades. Because of the conversion of much of its former habitat to agriculture, the royal catchfly is considered threatened in Indiana. The species' historical and present-day distribution in the State, documenting the current status of all known locations, including population sizes and co-occurring species, are reported in this paper. Only 8 of the documented 23 historical locations still support the plant. No populations occur in dedicated nature preserves or …

Effect Of Semen Storage On The Number Of Spermatozoa In The Perivitelline Layer Of Laid Turkey Eggs, A. M. Donoghue, M. R. Bakst, D. R. Holsberger, D. J. Donoghue

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A progressive decline in fertility over the course of egg production may be observed when turkey hens are inseminated weekly with semen stored for 24 h. In vitro storage of spermatozoa before insemination results in lower fertilization, possibly because fewer spermatozoa survive selection and storage in the hen's sperm storage tubules in vivo; alternatively, stored spermatozoa may be as capable of reaching the egg as are fresh spermatozoa, but unable to penetrate and fertilize the egg normally. The objective of this study was to determine whether this decline in fertility is a result of fewer spermatozoa reaching the egg …

Quantitative Mass Production Of Hydrotaea Aenescens (Diptera: Muscidae), Jerome Hogsette, Frank Washington

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A covered oviposition device was developed that allows collection of large numbers of Hydrotaea aenescens (Wiedemann) (formerly Ophyra aenescens) eggs. Eggs can be measured and known numbers added to larval rearing medium so this beneficial fly can be reared quantitatively for the first time. With the use of quantitative rearing techniques and a new diet consisting of 5 parts Gainesville house fly diet and 1 part meat and bone meal, H. aenescens can be mass-reared easily for biological control studies.

Sodium In Pasture Species And Grazing Livestock, C. T. Dougherty, Kenneth L. Wells, G. E. Mitchell

Agronomy Notes

Concern among some dairy nutritionists has recently been expressed that "high potassium" content of hay and silage is reducing milk production in some high-producing dairy herds. Alfalfa and grass hay and com and grass silage, which have been heavily fertilized, are the objects of this concern. The nutritional question being considered in this article is whether an animal diet excessively high in potassium (1

The Vascular Flora, Rare Species And Plant Migrations Of New River Gorge National River, West Virginia, Dale William Suiter

Theses, Dissertations and Capstones

In 1978, the United States Congress designated 83.5 km/53 mi. of the New River in southern West Virginia as New River Gorge National River. The vascular flora of selected sites in NRGNR was surveyed from September 1992 through October 1994. A total of 904 taxa of vascular plants was recorded, 79.2% of which are native to West Virginia. Currently, 1337 vascular plant taxa have been documented from the New River Gorge as a result of this work as well as the work of Grafton and McGraw and Phillips. A comparison of species with the West Virginia Natural Heritage Program's rare …

Crude Protein, And Other Chemical Constituents Of Corn Hybrids Evaluated In The 1994 Kentucky Hybrid Corn Performance Tests, C. G. Poneleit, K. O. Evans, Michael Collins

Agronomy Notes

Grain samples have been collected each year since 1990 from three locations of the Kentucky Hybrid Corn Performance Test and analyzed for crude protein (CP). The objective was to provide an unbiased comparative evaluation of the CP concentration of com hybrids sold in Kentucky. The results indicate that while management and environment at each test location may have significant influences, CP does differ among hybrid genotypes. The feeding value of specific hybrid genotypes based on their protein concentration may have significant influence in diet formulation for non-ruminant animals due to the amount of supplement needed to properly balance the diet, …

Modeling The Population Dynamics And Economics Of Velvet Leaf (Abutilon Theophrasti) Control In A Corn (Zea Mays)-Soybean (Glycine Max) Rotation, John L. Lindquist, Bruce D. Maxwell, Douglas D. Buhler, Jeffrey L. Gunsolus

Department of Agronomy and Horticulture: Faculty Publications

A simulation model was developed to predict the population dynamics and economics of velvetleaf control in a corn-soy bean rotation. Data compiled from the literature were used to parameterize the model f or two situations, one in which velvetleaf was infected by a Verticillium spp. wilt and one without infection. Verticillium was assumed to have no effect on corn or soybean yield. In the absence of control, simulated seed bank densities of a Verticillium-infected velvetleaf population were 5 to 50 times lower than for an uninfected velvetleaf population. The model was used to evaluate a threshold weed management strategy …

Local Action Of Trophoblast Interferons In Suppression Of The Development Of Oxytocin And Oestradiol Receptors In Ovine Endometrium, G. E. Lamming, D. C. Wathes, A. P. F. Flint, J. H. Payne, K. R. Stevenson, J. L. Vallet

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Luteolysis in sheep is associated with uterine secretion of pulses of prostaglandin F_2α(PGF_2α) due to the action of luteal oxytocin on endometrial oxytocin receptors. For pregnancy to become established inhibition of oxytocin receptors is important as an antiluteolytic mechanism. The maternal recognition of pregnancy in cattle and sheep involves production, by the trophoblast, of a type 1 interferon (IFN-τ)that suppresses uterine development of oxytocin receptors and the generation of luteolytic episodes of PGF_2α. The action of IFN-τ in surgically prepared unilaterally pregnant ewes was investigated. Finn-Dorset ewes were anaesthetized on day 6 or 7 …
