Indirect Effects Of Carnivores On Livestock Foraging Behavior And Production, Larry D. Howery, Thomas J. Deliberto

Sheep and Goat Research Journal

Direct effects of predation (i.e., killing of animals) can result in significant economic losses to livestock producers. A recent publication by the USDA, Wildlife Services (2002) identified the following losses: (1) livestock losses attributed to predators, predominantly coyotes (Canis latrans), reach about $71 million annually; (2) cattle and calf losses to predators in the United States totaled 147,000 head during 2000. A National Agricultural Statistics Service (NASS) study valued these losses at $51.6 million; (3) sheep and lamb losses to predators in the United States totaled 273,000 in 1999. A NASS study valued these losses at $16.5 million; (4) In …

Status And Management Of Coyote Depredations In The Eastern United States, John M. Houben

Sheep and Goat Research Journal

The populations of coyotes (Canis latrans) have increased dramatically in the eastern United States since the early 1900s (Hilton, 1978; Chambers, 1987; Hill et al., 1987; Witmer and Hayden 1992). The expansion of the coyote range into eastern North America has been summarized by Parker (1995) and characterized as two distinct geographical events: 1) the northern front moving across southern Ontario and the Great Lakes region and 2) the southern front colonizing the southeastern United States from Arkansas and Louisiana. These two fronts expanded throughout the northeastern and southeastern United States during the 1960s and 1970s, finally converging …

Heritability Estimates For Carcass Traits Of Cattle: A Review, Angel Rios Utrera, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

We present estimates of heritability for carcass traits of cattle published in the scientific literature. Seventy-two papers published form 1962 to 2004, which reported estimates of heritability for carcass traits, were reviewed. The unweighted means of estimates of heritability for 14 carcass traits by slaughter end point (age, weight, and fat depth) were calculated. Among the three end points, carcass weight, backfat thickness, longissimus muscle area, and marbling score were the carcass traits with the most estimates of heritability (56≤n≤66). The averages for these traits indicate that they are similarly and moderately heritable (0.40, 0.36, 0.40, and 0.37, respectively). However, …

Vulture-Cattle Interactions At A Central Florida Ranch, John S. Humphrey, Eric A. Tillman, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

Black vulture depredations to newborn livestock, poultry, and other captive animals have been reported from at least 15 states, and during the 1990s, reports of depredations increased annually by an average of 18%. In response to this issue, we initiated a study at Buck Island Ranch of the MacArthur Agro-Ecology Research Center in central Florida to examine interactions between cattle and vultures. Based on previous reports, we hypothesized that vulture predation selectively targets calves of young, inexperienced cows. To document vulture activity, we conducted point counts of vultures in pastures throughout the ranch from January 2000 to March 2001. During …

Ec04-835 Hedging And Basis Considerations For Feeder Cattle Livestock Risk Protection Insurance, Darrell R. Mark

University of Nebraska-Lincoln Extension: Historical Materials

Livestock Risk Protection (LRP) insurnace for feeder cattle is a price-risk management tool initially offered in June 2003 to feeder cattle producers in Nebraska, Colorado, Illinois, Iowa, Kansas, Nevada, Oklahoma, South Dakota, Texas, Utah, and Wyoming.

This extension circular examines historical LRP basia dn demonstrates its use in hedging with LRP.

Ec04-834 Hedging And Basis Considerations For Fed Cattle Livestock Risk Protection Insurance, Darrell R. Mark

University of Nebraska-Lincoln Extension: Historical Materials

Livestock Risk Protection (LRP) Insurance for fed cattle is a price-risk management tool initially offered in June 2003 to fed cattle producers in Nebraska, Iowa, and Illinois. LRP indemnifies against declines in cash fed cattle sales prices, as measured by a regional weekly weighted average cash slaughter steer price.

This 2004 extension circular examines historical LRP basis and demonstrates its use in hedging with LRP.

Ec04-834 Hedging And Basis Considerations For Fed Cattle Livestock Risk Protection Insurance, Darrell Mark

University of Nebraska-Lincoln Extension: Historical Materials

Extension Circular 04-834: This circular contains information on cattle prices and what to consider when buying and selling cattle. It also contains several tables and charts to give more statistical information on cattle prices and LRP.

Building Beef Cow Nutritional Programs With The 1996 Nrc Beef Cattle Requirements Model, G. P. Lardy, Don C. Adams, Terry J. Klopfenstein, H. H. Patterson

Department of Animal Science: Faculty Publications

Designing a sound cow-calf nutritional program requires knowledge of nutrient requirements, diet quality, and intake. Effectively using the NRC (1996) beef cattle requirements model (1996 NRC) also requires knowledge of dietary degradable intake protein (DIP) and microbial efficiency. Objectives of this paper are to 1) describe a framework in which 1996 NRC-applicable data can be generated, 2) describe seasonal changes in nutrients on native range, 3) use the 1996 NRC to predict nutrient balance for cattle grazing these forages, and 4) make recommendations for using the 1996 NRC for forage-fed cattle. Extrusa samples were collected over 2 yr on native …
