        7 unique strains of CWD, that's really interesting.

        Comment


          The TRUTH:

          We dont fully understand the disease, not even close.

          It can certainly be spread by the movement of animals/infected carcasses

          It is not FULLY political, it is a real disease.

          The consequences of the disease have not been detrimental on a population level scale anywhere it is found.

          Deer breeders need to understand there will always be rules (and new rules) to follow when privately holding public wildlife.

          TPWD needs to understand they allowed , and formerly encouraged, deer breeding and understand breeders are not fully to blame.

            I’ll ask to this, not directed at you Michael, what did TPWD do about the Kerr WMA positive deer? And didn’t they move a positive deer out of San Antonio?

            I’m sure some BS will be copy and pasted. And more BS about how breeders are bad. By folks that being absolutely nothing else to this forum.

            breeders bad. CWD gonna wipe us out. All deer gonna die. Hurry the sky is falling.



            Much like our national political environment, we cannot get unbiased, factual answers. Because an agenda is being pushed. And it’s beyond getting old.

                Per TPWD it was a “false positive “ that was followed by back to back negative results. I can’t confirm or deny if that’s the truth.

                Another thing I hate about CWD is that private interests on both sides hurl money at beating the other side. They both hate each other, always will.

                  I hear guys say that "they are trying to make money off of it" in regards to people/groups/ranchers who are "against" breeder deer.

                  Im curious how they are trying to make money? The only ones that seem to make money are the ones for deer breeding and deer breeders.

                    There is a belief among the breeding industry that certain large landholders arent happy that now anyone can kill a big deer on a HF place, lowering the value of their deer hunts.

                    Comment


                      Yes, thats what deer breeders are saying, but lets be honest....

                      Large landowners are not missing out on income from these deer breeders. They are charging more than ever for their deer and their leases. A large landowner has a different clientale than the average "shoot and take" hunting place, which are normally under 1,000 acres and in central texas.

                      The only ones loosing money are the outfitters, landowners, and deer breeders who try to squeaze out as much money from their property as possible. Selling 20 deer hunts on 800 acres in kerrville for 170-400" deer EACH season is a perfect example. Those are the guys who are worried about this being a money deal, not the large lf landowners are the hf landowners with native herds.

                      I wish the pro deer breeders would stop saying its all about money because that is just a lie.

                      Comment


                        Also alot, if not all, of the tpw board members who are listed by breeders as being personally worried about loosing money, are each some of the largest and wealthiest landowners in Texas. They do not offer hunts on their ranches, and if they did, they would get top dollar.

                        Do you really think people like the Bass family, Hughes, freidkins, or Appleton really look over all they own and have at their disposle and think they are upset because some people are making money off of pen deer and they arent? Its just comical to me, to think, billionares really care about $7,000 250" deer.

                          CWD POPULATION DECLINES

                          CWD poses a significant threat to the future of hunting in Texas. Deer population declines of 45 and 50 percent have been documented in Colorado and Wyoming. A broad infection of Texas deer populations resulting in similar population impacts would inflict severe economic damage to rural communities and could negatively impact land markets. Specifically, those landowners seeking to establish a thriving herd of deer could avoid buying in areas with confirmed CWD infections. As they do with anthrax-susceptible properties, land brokers may find it advisable to inquire about the status of CWD infections on properties that they present for sale. Prospective buyers should also investigate the status of the wildlife on prospective properties. In addition, existing landowners should monitor developments as TPWD crafts management strategies to identify and contain this deadly disease.

                          Dr. Gilliland (c-gilliland@tamu.edu) is a research economist with the Texas Real Estate Research Center at Texas A&M University.

                          There's a disease lurking where the deer and the antelope play, and it has the potential to significantly reduce the deer population. There are ways to contain it, though, and the Texas Parks and Wildlife Department has a plan.


                          Colorado CWD TSE Prion Detected in 40 of 54 deer herds, 17 of 42 elk herds, and 2 of 9 moose herds



                          Colorado Chronic Wasting Disease Response Plan December 2018.

                          Executive Summary Mule deer, white-tailed deer, elk and moose are highly valued species in North America. Some of Colorado’s herds of these species are increasingly becoming infected with chronic wasting disease(CWD).

                          As of July 2018, at least 31 of Colorado's 54 deer herds (57%), 16 of43 elk herds (37%), and 2 of 9 moose herds (22%) are known to be infected with CWD.

                          Four of Colorado's 5 largest deer herds and 2 of the state’s 5 largest elk herds are infected.

                          Deer herds tend to be more heavily infected than elk and moose herds living in the same geographic area.

                          Not only are the number of infected herds increasing, the past 15 years of disease trends generally show an increase in the proportion of infected animals within herds as well.

                          Of most concern, greater than a 10-fold increase in CWD prevalence has been estimated in some mule deer herds since the early 2000s; CWD is now adversely affecting the performance of these herds.

                          snip...(the map on page 71, cwd marked in red, is shocking...tss)





                          How does CWD impact deer, elk, and moose populations?

                          Recent research in Wyoming has demonstrated declines in both mule and white-tailed deer populations in deer hunt area 65 due to CWD (see below for citations). These declines are in the core endemic area where prevalence is highest. In areas with lower prevalence, effects of CWD are poorly understood but are considered additive along with other factors that can negatively affect deer populations in Wyoming (i.e. habitat loss, predation, other diseases). The distribution and prevalence of CWD in Wyoming elk is less than that of deer. Currently there are no documented direct population impacts in Wyoming elk from CWD; however, research from Rocky Mountain National Park suggests that CWD could impact elk populations at higher prevalence (13%). While CWD has been found in free ranging moose, there have been few detections, and there is no evidence that CWD is currently having an impact on moose populations.

                          Chronic wasting disease (CWD) is a chronic, fatal disease of the central nervous system in mule deer, white-tailed deer, elk, and moose.

                          Chronic Wasting Disease In Cervids: Prevalence, Impact And Management Strategies

                          Nelda A Rivera,1 Adam L Brandt,2 Jan E Novakofski,3 and Nohra E Mateus-Pinilla1

                          snip...

                          Chronic wasting disease has an ecologic, economic and social effect, with deep impact on the viability of cervid populations. An experimental study found a 60% decline in full-term viable offspring born to CWD-positive muntjac dams.48 Modeling studies have shown an annual population decline of 10.4% in white-tailed deer and 21% in sympatric mule deer populations in southeastern Wyoming, corroborating the population-limiting impact of CWD.115,116 Survival estimates indicate that CWD-infected mule deer were 4.5 more likely to die annually compared to CWD-negative deer116 and were more susceptible to predation than uninfected deer.117 The impact on elk populations in endemic areas in Colorado and South Dakota has also shown declines in survival118 and decrease in population growth rates.119 Conversely, the impact of CWD in low-density deer populations differs from places with high-density populations. Mule deer living in arid San Andres Mountains—part of the Chihuahuan Desert-range in southern New Mexico—showed weak population effects based on CWD prevalence and mortality data.120 Models reveal mixed results in long-term survival of cervid populations based on observed epidemics in endemic areas of Wisconsin, Colorado and Wyoming. Outcomes ranged from small host declines to moderate epidemics, and in some cases, to complete host extinction.121 Captive cervid facilities have been impacted by CWD, with over 175 herd facilities affected across the US and reported infection rates as high as 80% at some of these facilities.122 The extent of disease impact in other parts of the world is less understood. Because of the limited surveillance across Europe—especially in remote areas—it is not possible to exclude the possibility that CWD has been affecting cervids across Europe for decades.91,93

                          Abstract

                          Chronic wasting disease (CWD) is an invariably fatal transmissible spongiform encephalopathy of white-tailed deer, mule deer, elk, and moose. Despite a 100% fatality rate, areas of high prevalence, and increasingly expanding geographic endemic areas, little is known about the population-level effects of CWD in deer. To investigate these effects, we tested the null hypothesis that high prevalence CWD did not negatively impact white-tailed deer population sustainability. The specific objectives of the study were to monitor CWD-positive and CWD-negative white-tailed deer in a high-prevalence CWD area longitudinally via radio-telemetry and global positioning system (GPS) collars. For the two populations, we determined the following: a) demographic and disease indices, b) annual survival, and c) finite rate of population growth (λ). The CWD prevalence was higher in females (42%) than males (28.8%) and hunter harvest and clinical CWD were the most frequent causes of mortality, with CWD-positive deer over-represented in harvest and total mortalities. Survival was significantly lower for CWD-positive deer and separately by sex; CWD-positive deer were 4.5 times more likely to die annually than CWD-negative deer while bucks were 1.7 times more likely to die than does. Population λ was 0.896 (0.859-0.980), which indicated a 10.4% annual decline. We show that a chronic disease that becomes endemic in wildlife populations has the potential to be population-limiting and the strong population-level effects of CWD suggest affected populations are not sustainable at high disease prevalence under current harvest levels.

                          DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being introduced into Great Britain? A Qualitative Risk Assessment October 2012

                          snip.....

                          In the USA, under the Food and Drug Administration's BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system. However, this recommendation is guidance and not a requirement by law.

                          Animals considered at high risk for CWD include:

                          1) animals from areas declared to be endemic for CWD and/or to be CWD eradication zones and

                          2) deer and elk that at some time during the 60-month period prior to slaughter were in a captive herd that contained a CWD-positive animal.

                          Therefore, in the USA, materials from cervids other than CWD positive animals may be used in animal feed and feed ingredients for non-ruminants.

                          The amount of animal PAP that is of deer and/or elk origin imported from the USA to GB can not be determined, however, as it is not specified in TRACES. It may constitute a small percentage of the 8412 kilos of non-fish origin processed animal proteins that were imported from US into GB in 2011.

                          Overall, therefore, it is considered there is a __greater than negligible risk___ that (nonruminant) animal feed and pet food containing deer and/or elk protein is imported into GB.

                          There is uncertainty associated with this estimate given the lack of data on the amount of deer and/or elk protein possibly being imported in these products.

                          snip.....

                          36% in 2007 (Almberg et al., 2011). In such areas, population declines of deer of up to 30 to 50% have been observed (Almberg et al., 2011). In areas of Colorado, the prevalence can be as high as 30% (EFSA, 2011).

                          The clinical signs of CWD in affected adults are weight loss and behavioural changes that can span weeks or months (Williams, 2005). In addition, signs might include excessive salivation, behavioural alterations including a fixed stare and changes in interaction with other animals in the herd, and an altered stance (Williams, 2005). These signs are indistinguishable from cervids experimentally infected with bovine spongiform encephalopathy (BSE).

                          Given this, if CWD was to be introduced into countries with BSE such as GB, for example, infected deer populations would need to be tested to differentiate if they were infected with CWD or BSE to minimise the risk of BSE entering the human food-chain via affected venison.

                          snip.....

                          The rate of transmission of CWD has been reported to be as high as 30% and can approach 100% among captive animals in endemic areas (Safar et al., 2008).

                          snip.....

                          In summary, in endemic areas, there is a medium probability that the soil and surrounding environment is contaminated with CWD prions and in a bioavailable form. In rural areas where CWD has not been reported and deer are present, there is a greater than negligible risk the soil is contaminated with CWD prion.

                          snip.....

                          In summary, given the volume of tourists, hunters and servicemen moving between GB and North America, the probability of at least one person travelling to/from a CWD affected area and, in doing so, contaminating their clothing, footwear and/or equipment prior to arriving in GB is greater than negligible... For deer hunters, specifically, the risk is likely to be greater given the increased contact with deer and their environment. However, there is significant uncertainty associated with these estimates.

                          snip.....

                          Therefore, it is considered that farmed and park deer may have a higher probability of exposure to CWD transferred to the environment than wild deer given the restricted habitat range and higher frequency of contact with tourists and returning GB residents.

                          snip.....
