Evaluation Of Lifetimewool: 2008 National Farmer Survey Results, Anne Jones, Andrew Van Burgel, Gus Rose

All other publications

Key components of the lifetimewool evaluation plan were two National producer surveys to quantify change in the knowledge, attitudes, skills and aspirations over the duration of the project. In 2005, 2032 wool producers were surveyed to establish a benchmark for ewe and pasture management practices, knowledge and willingness to change. At that time, 93% of those who were surveyed said that they were willing to be resurveyed in 2008 at the completion of the project. This has allowed lifetimewool to compare individual producers’ changes in practices, knowledge and willingness over the three years that the communication and adoption phase of …

Pastoral Profits Guide, A Paddock Guide To Achieving Sustainable Livestock Productivity, Mark Alchin, Jim Addison, Valarie Shrubb, Zac Cockerill, Matthew Young, Tim Johnson, Greg Brennan

All other publications

Most pastoralists appreciate the need to deliver an economic, environmental and social 'profit' from their business. Achieving these profits can be a real challenge given the comparatively low productive potential and the substantial seasonal variation in the WA Southern Rangelands region. This guide was written to assist pastoralists to meet their specific livestock production, financial and range condition objectives through the better alignment of feed demand (stocking rate) to feed supply (carrying capacity). We provide nine basic steps that simplify the process of managing the feed supply, equipping pastoralists with the tools to make· decisions and to critically assess the …

The Determination Of The Shelf Life And Some Nutritional Components Of Gilthead Seabream (Sparus Aurata L., 1758) After Cold And Hot Smoking, Şengül Bi̇lgi̇n, Mustafa Ünlüsayin, Levent İzci̇, Ali̇ Günlü

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine the shelf life, as well as chemical and microbiological quality of gilthead seabream (Sparus aurata L., 1758) prepared by 2 different methods of smoking (hot smoking and cold smoking). The effects of hot and cold smoking on the chemical composition and microbial load of gilthead seabream, as well as organoleptic analysis of the smoked product were investigated. Significant (P < 0.05) differences were found in the chemical composition of fresh and smoked seabream. The panelists liked the hot smoked fish more than the cold smoked fish, according to sensory analysis results. Changes in pH, thiobarbituric acid (TBA), and total volatile basic nitrogen (TVB-N) values were significant (P < 0.05) during storage at 4 °C. Microbiological analysis results demonstrated that the smoking techniques reduced the microbial content of the fish, whereas microbial content increased during storage. The smoking methods tested had a small effect on the level of vitamin D_3 in gilthead seabream.

Influence Of Additives And Fermentation Periods On Silage Characteristics, Chemical Composition, And In Situ Digestion Kinetics Of Jambo Silage And Its Fodder In Nili Buffalo Bulls, M. Aasif Shahzad, Muhammad Sarwar, Mahr-Un Nisa, N. A. Tauqir

Turkish Journal of Veterinary & Animal Sciences

Jambo grass (Sorghum bicolour x Sorghum sudanefe) harvested 50 days after sowing was ensiled in laboratory silos using 2 additives, cane molasses and ground corn grains, each at the rate of 2%, 4%, and 6% levels for 30, 35, and 40 days at room temperature (28 °C). Data regarding incubation days were pooled. The pH and lactic acid concentration in jambo grass silage were not affected by the additive type, level, or fermentation period. Dry matter (DM) content of jambo silage was significantly (P < 0.05) affected by additive type; however, additive levels and fermentation periods did not affect its DM contents. Crude protein content of jambo grass was not affected by ensiling time, additive type, or level. The true protein contents of jambo grass silage were significantly (P < 0.05) higher with molasses than with ground corn. Neutral detergent fiber (NDF) and hemicellulose content of jambo grass were significantly (P < 0.05) affected by additives and their levels, but fermentation periods did not influence the NDF contents of jambo grass silage. Cellulose, acid detergent fiber, and acid detergent lignin contents of jambo silage were not affected by additive type, level, or fermentation period. Therefore, jambo grass ensiled with 2% molasses for 30 days was selected for in situ digestion kinetics in bulls. Dry matter and NDF degradabilities of jambo grass were significantly higher than those of its silage at 48 h of ruminal incubation. Ruminal lag time, and rate and extent of DM and NDF degradation were similar for jambo grass and its silage. The results of this study implied that jambo grass ensiled with 2% molasses for 30 days has similar nutritive value to that of its forage in bulls.

Feather Molt Of Nonmigratory Whooping Cranes In Florida, Martin J. Folk, Stephen A. Nesbitt, Jeannette M. Parker, Marilyn G. Spalding, Stephen B. Baynes, Kristen L. Candelora Jan 2008

Feather Molt Of Nonmigratory Whooping Cranes In Florida, Martin J. Folk, Stephen A. Nesbitt, Jeannette M. Parker, Marilyn G. Spalding, Stephen B. Baynes, Kristen L. Candelora

Proceedings of the North American Crane Workshop

Molt patterns of wild whooping cranes (Grus americana) are largely unknown, and what knowledge we have has been based on scant data. We documented patterns of feather molt in nonmigratory whooping cranes in Florida during 1993-2005. All birds replaced flight feathers (remiges) in a synchronous (simultaneous) manner and spent time flightless. It took 38-46 days (mean = 44 days, n = 8) for feathers to regrow and birds to regain flight ability. When flightless due to remigial molt, cranes became more secretive and spent more time in wetlands during feather regrowth. Most (70%) whooping cranes first molted their …

Risk Factors Associated With Developmental Limb Abnormalities In Captive Whooping Cranes, Cristin Kelley, Barry K. Hartup Jan 2008

Risk Factors Associated With Developmental Limb Abnormalities In Captive Whooping Cranes, Cristin Kelley, Barry K. Hartup

Proceedings of the North American Crane Workshop

This retrospective survey identifies potential risk factors for developmental limb abnormalities in whooping crane (Grus americana) chicks reared at the International Crane Foundation between 1990 and 2006. We summarized a series of biologicallyrelevant pre- and post-hatch variables from this population using in-house aviculture and veterinary records, and then compared them between chicks with and without developmental carpal, toe and leg deformities. Chi-square analysis revealed associations between 1) rearing style and each type of deformity, 2) egg source and carpal and toe deformities, and 3) the pre-existence of a toe deformity and carpal and leg deformities. Multivariate analyses using …

A Low Intensity Sampling Method For Assessing Blue Crab Abundance At Aransas National Wildlife Refuge And Preliminary Results On The Relationship Of Blue Crab Abundance To Whooping Crane Winter Mortality, Bruce H. Pugesek, Michael J. Baldwin, Thomas V. Stehn

Proceedings of the North American Crane Workshop

We sampled blue crabs (Callinectes sapidus) in marshes on the Aransas National Wildlife Refuge, Texas from 1997 to 2005 to determine whether whooping crane (Grus americana) mortality was related to the availability of this food source. For four years, 1997 - 2001, we sampled monthly from the fall through the spring. From these data, we developed a reduced sampling effort method that adequately characterized crab abundance and reduced the potential for disturbance to the cranes. Four additional years of data were collected with the reduced sampling effort methods. Yearly variation in crab numbers was high, ranging …

Effects Of Nutrition During Gilt Development On Lifetime Productivity Of Sows Of Two Profile Maternal Lines: Summary Of Growth Characteristics And Sow Productivity – 2008, Phillip S. Miller, Rodger K. Johnson, Roman Moreno, Matthew W. Anderson, Jeffrey M. Perkins, Donald R. Mcclure, Thomas Mcgargill

Nebraska Swine Reports

An experiment was conducted to determine the effects of energy restriction during the gilt development period on lifetime sow reproductive performance of two maternal lines. There were essentially no interactions among line, dietary treatment, and parity. The Large White x Landrace gilts were heavier before and after dietary treatments, matured later, and had greater longissimus muscle area compared to Nebraska Line gilts. Restricting energy intake during the developmental period increased litter weaning weight but had no affect on litter size. Nutritional management of prolific sow lines during the gilt development period does affect sow and litter performance. However, these results …

The Effect Of Corn Distillers Dried Grain With Solubles (Ddgs) On Carcass Characteristics And Pork Quality, Roman Moreno, Phillip S. Miller, Thomas E. Burkey, Steven J. Jones, Susan L. Cuppett, Timothy P. Carr, Tommi Jones, Ruth M. Diedrichsen

Nebraska Swine Reports

A study was conducted to evaluate the effect of feeding 0,5,10 or 15% distillers dried grains with solubles (DDGS) on carcass quality, color stability, and sensory characteristics of the longissimus muscle (LM) of finishing pigs. Live weight and hot carcass weight decreased as dietary DDGS increased (P < 0.05). Dressing percentage did not differ among treatments (P - 0.72). After 10 days of retail display, no differences were observed among treatments for color or color change (P > 0.05). No differences in shear force were observed (P = 0.34). Total unsaturated fatty acids increased and total saturated fatty acids decreased (P < 0.05) as dietary DDGS increased. Treatments did not affect sensory characteristics (P > 0.05). The results of this investigation suggest that dietary DDGS inclusion altered fatty acid profile of the backfat of pigs by reducing total saturated fatty acid and increasing total unsaturated …

Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck Jan 2008

Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck

Human–Wildlife Interactions

Bears (Ursus spp.) that become conditioned to anthropogenic food sources pose a risk to human safety and generally need to be relocated, rehabilitated, or destroyed. Identifying food-conditioned bears may be difficult if the animal is not captured or killed while immediately engaged in the nuisance behavior. Fatty acid signature analysis has been used to examine the dietary habits of bears and other carnivores and is based on the predictable incorporation of ingested fatty acids into the consumer’s fat stores. Unusual fatty acids that are available in only a few food types may be particularly useful dietary markers. In this …

Landscape And Traffic Factors Influencing Deer–Vehicle Collisions In An Urban Enviroment, Janet W. Ng, Charlene Nielsen, Colleen Cassady St. Clair Jan 2008

Landscape And Traffic Factors Influencing Deer–Vehicle Collisions In An Urban Enviroment, Janet W. Ng, Charlene Nielsen, Colleen Cassady St. Clair

Human–Wildlife Interactions

Deer–vehicle collisions (DVCs) are steadily increasing across North America. The increase is particularly pronounced in urban green spaces where deer (Odocoileus spp.) populations and road densities are high. In the greater city of Edmonton, Alberta, Canada, 333 DVCs occurred from 2002 to 2004. To identify landscape and traffic correlates of these collisions, we built 3 statistical models. The first model assessed the importance of local variables and was based on a spatial precision of the nearest intersection to which collisions were referenced. The second model was based on landscape characteristics and used the nearest township intersection to aggregate collisions. …

Deer–Vehicle Collision Prevention Techniques, Lauren L. Mastro, Michael R. Conover, S. Nicole Frey Jan 2008

Deer–Vehicle Collision Prevention Techniques, Lauren L. Mastro, Michael R. Conover, S. Nicole Frey

Human–Wildlife Interactions

Every year in the United States approximately 1.5 million deer–vehicle collisions (DVCs) occur resulting in >29,000 human injuries, >200 human fatalities, 1.3 million deer fatalities, and >1 billion dollars worth of property damage. Despite the magnitude of this problem, there are relatively few well-designed studies that have evaluated techniques that can be used to reduce DVCs. Techniques to reduce DVCs fall into 4 categories: reducing the number of deer (Odocoileus spp.), reducing the number of vehicles, modifying deer behavior, and changing motorist behavior. Techniques to reduce the number of deer include decreasing the deer population or excluding deer from …

Human–Wildlife Interactions

Immunocontraceptive vaccines based on gonadotropin-releasing hormone (GnRH) have been tested in adult white-tailed deer (Odocoileus virginianus), but their effects on fawns are unknown. The purpose of this study was to determine if early immunization against GnRH would induce a long-lasting immune response in fawns, and if it would delay or prevent sexual development. We gave primary and subsequent booster injections of a KLH-GnRH/Freund’s vaccine to 6 male and 6 female fawns. This vaccine contained the same active ingredients as GonaCon™ vaccine, but it contained Freund’s adjuvant instead of AdjuVac™ adjuvant. Two 450-μg injections were given 1 month apart …
