Animal Welfare--Animal Rights: Role Of Grazing, Roy Burris
Kentucky Grazing Conference
The care and handling of farm animals has drawn a lot of media attention lately. Some well-publicized events have given our industry the proverbial black-eye and led to a chain of events that has left livestock producers feeling very vulnerable to negative attacks. Although these events have been very isolated, they have had some very farreaching effects. Could they have been prevented? How? What do we do now?
Extended Grazing And Reduced Stored Feed, Edward N. Ballard
Extended Grazing And Reduced Stored Feed, Edward N. Ballard
Kentucky Grazing Conference
Feed costs represent the major cost in most livestock production systems. A recently completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation. Typically the cost of supplying nutrients to ruminant livestock is much greater using harvested feedstuffs as opposed to grazing pastures or crop residues. The primary function of a grassland farm is to convert solar energy to marketable livestock products in the most efficient manner. The fewer steps between the animal product and …
Stored Feed Needs: How Much? What Quality?, Jeff Lehmkuhler
Stored Feed Needs: How Much? What Quality?, Jeff Lehmkuhler
Kentucky Grazing Conference
Feed resources are the largest variable expense in beef production systems outside the initial investment in the livestock. When we look at Standardized Performance Analysis (SPA) information from Texas and Minnesota, states that are at the extreme from an environment stance, the projected costs for maintaining a beef cow are strikingly similar. It is important to note that these costs include all expenses and opportunity costs. Getting back to the SPA information, in 2007 the annual cost to maintain a cow in Texas was determined to be roughly $590 while the Minnesota value was near $610 or only about $20/cow …
Tall Fescue Grazing Research, Glen Aiken
Tall Fescue Grazing Research, Glen Aiken
Kentucky Grazing Conference
‘Kentucky-31’ tall fescue, like it or hate it, covers 5 million acres of Kentucky and if you do not have it on your farm, it is likely that one of your bordering neighbors does! Tall fescue owes its persistence and productivity in large part to a fungal endophyte that infects most plants. This endophyte produces an array of alkaloids that benefit the plant in tolerating heat, drought, and grazing. Unfortunately, the endophyte also produces ergot alkaloids that can cause “fescue toxicosis” in cattle. Cattle inflicted with toxicosis have reduced dry matter intake, elevated body temperature, and often retain their winter …
Weed Control Options For Pastures, Jon Doran
Weed Control Options For Pastures, Jon Doran
Kentucky Grazing Conference
What is a weed? A pasture or hayfield “weed” is any plant that you deem as being out of place and/or a plant that is decreasing your desired forage production. Weeds may be classified in several ways including broadleaf weeds, woody plants, and undesirable grasses. Besides decreasing forage, weeds can also interfere with forage utilization, grazing distribution, etc. There are several methods available to control weeds and increase production of and access to desirable forages. The three main methods are cultural, mechanical, and chemical. The cultural method is quite simple-a thriving grass stand is an excellent form of weed control …

Our Experiences With Eastern Gamagrass, Tommy R. Yankey
Kentucky Grazing Conference
As livestock producers try to reduce their cost of production, many look at ways to reduce their feed costs. Feed costs have been identified as the largest single cost of livestock production, making up 50 to 70% of the total cost of production. Grazing is the cheapest way to feed cattle on a cost per pound of nutrient basis.

New Developments In Grazing Species And Varieties, S. Ray Smith
Kentucky Grazing Conference
During the last 10 years there have been several new forage species that have emerged as useful in grazing systems and many new varieties have been released of traditional species. Plant breeders continue to make improvement in our traditional pasture species like tall fescue, orchardgrass, and red and white clover. In the following paragraphs, I will focus more on some of the forage species that you may not be as familiar with and highlight the advancements occurring in developing new varieties for grazing. There are many sources of information on this subject. I especially encourage you to read the new …

Networks - Ii: Optimal Fractional Frequency Reuse (Ffr) And Resource Allocation In Multiuser Ofdma System, Naveed Ul Hassan, Mohamad Assaad
International Conference on Information and Communication Technologies
In this paper we determine the optimal fractional frequency reuse (FFR) and resource allocation in OFDMA system. Since the users at the cell edge are more exposed to inter-cell interference therefore each cell is partitioned into two regions; inner region and outer region. We determine the optimal FFR factor for the outer region, bandwidth assigned to each region and subcarrier and power allocation to all the users in the cell. The problem is formulated as sum-power minimization problem subject to minimum rate constraints in both the regions. This is a mixed linear integer programming problem which is relaxed into a …

International Conference on Information and Communication Technologies
Putting constraints on performance of a system in the temporal domain, some times turns right into wrong and update into outdate. These are the scenarios where apposite value of time inveterate in the reality. But such timing precision not only requires tightly scheduled performance constraints but also requires optimal design and operation of all system components. Any malfunctioning at any relevant aspect may causes a serious disaster and even loss of human lives. Managing and interacting with such real-time system becomes much intricate when the resources are limited as in wireless sensor nodes. A wireless sensor node is typically comprises …

Wireless Networks: Certificateless Id-Based Authentication Using Threshold Signature For P2p Manets, Aasia Samreen, Seema Ansari
International Conference on Information and Communication Technologies
As far as the security of MANET (mobile and ad hoc network) is concerned, it depends upon the secure authentication especially for P2P MANETs. Identity based encryption was introduced to construct Public Key without requiring a certificate. Therefore, certificateless authentication combined with threshold digital signature and efficient key generation using identities such as IP address, are the challenging issues in front of researchers. In this paper we have addressed the problem of identity based secure authentication employing well-known RSA algorithm and secret sharing to generate threshold signature on a message.
