Livestock Concerns with Feral Hogs Livestock Concerns with Feral Hogs Aaron Sumrall Newton Co. Extension Agent History of Feral Hogs • Introduce to New World by De Soto in 1539 as a food source. • Made it to Texas in 1680’s. • Population explosion beginning in 1930 thru now……Why? – Great Depression….hardship of the 30’s. – Imported for hunting opportunities. What is the Current Status? • Population estimates of >1 million. • Occupy 244 of 254 counties. • 2007- Caused $52 million in Ag only. • $200/Hog/Year in Damage. • 42 of 50 States. Feral Hog Biology • Life expectancy of 4-5 years. • Reproductively capable of 6 months if nutrition is available. – 1st litter can be weaned before 1st birthday of sow. • Gestation of 115 days. • Average littler size of 4-6 piglets. • What do you call a group of feral hogs? Feral Hog Biology….Continued • Sounders typically of 6-12 individuals can be >30. • Mature hogs from 110-300 lbs. • Come in 3 flavors. – Eurasian Wild Boar – Domesticated hogs released – Combination of the two Areas of Feral Hog Damage • Agricultural:$52 million in 2007. • Disease • Predation • Habitat Destruction • Accidents • Sensitive Areas……example Wetlands. • Residential • Recreational • $800 million animal in Ag/Environmental. Areas of Feral Hog Damage...Continued • Length of tie required for land recovery. • Loss of topsoil. • Destruction of sensitive habitat. • Predation of livestock and wildlife population. • Introduction of other invasive species. – Reduction or loss of native vegetation. • Reduced water quality. – Roadway damage, etc…. What are Legal Options? • Hunting • Trapping • Dogs • Snares • Ariel Gunning What else is Legal? • Are you required to hold a hunting license shoot/hunt hogs? –It Depends!!! Is it Legal to Raise Feral Hogs? • NO! It is not legal to posses or feed feral hogs without a permit. Is it Legal to release Captured Feral Hogs? • IT DEPENDS. – *If captured, there are no laws to prevent release. – *It is illegal to transport and release . Is it Legal to Transport Feral Hogs? • IT DEPENDS. – Feral hogs can only be transported to locations holding a feral swine holding facility permit. – It is not legal to transport feral hogs to locations that do not possess the proper permits. What is the bag limit and hunting season for feral hogs? No bag limit!!! No closed season!!! What is not Legal? •Toxicants!!! •Home Chemical Concoctions!!! Are the any toxicants on the horizon for feral hog control? *Sodium Nitrite - Serious no target species concerns. - Delivery method concerns. Management Efficiency • Must become more efficient. – Increase of 500,000 in the last 10-12 years. • To hold populations steady constant, we must remove 70% of yearly production. • Management of hogs is based on convenience rather than necessity. Rangeland Concerns • Length of time required for land recovery. • Loss of topsoil. • Destruction of sensitive habitat. • Predation on livestock and wildlife populations. • Introduction of other invasive species. – Reduction or loss of native vegetation. • Reduced water quality and quantity. – Roadway damage, etc… Agricultural and Livestock Concerns • Depredate cattle and consume crops. • Contaminate water supply. • Disease • Loss of yield to pasture/hayland. Agricultural Economics & Feral Hogs • $800 million in agriculture and environmental loss annually. • Average of $7,515 in damage loss to agricultural land owners in Texas. • Average of $2,631 in control efforts annually. • Loss of weaned animals and female slow to rise. • Limbs of livestock fractured due to wallowing/rooting. Livestock Concerns • Will depredate cattle, sheep and goats. • Attracted to odor of afterbirth. • Harassment of livestock with young. • Cause perception of lack of production or predation. • Little evidence after depredation by feral hogs. • Usually seasonal depredation or brought on by a stress situation. Sheep and Goat Issues with Feral Hogs • Will feed on all age classes of goats. • Protection animals do not work (ex: donkey) • Feed on twin lambs 5-6 x more frequent than on single lambs. • When within 100m of sheep, feral hogs caught lambs in 24% of chases in research studies. • Hogs are second only to coyotes as predators to sheep and goats in some areas of the state. Disease Concerns • Reservoir of up to 30 diseases of concern. • Water contamination. • Some diseases are transmissible to humans and livestock. • Large concern in domestic swine production. • Relatively little known of potential disease magnitude in Texas. What should land managers be doing? • Learn how to read signs. • Have an ongoing approach to feral hog management. • Do not release captured hogs. • Take the IPM approach. – Integrated Pest Management. – Use everything that is legal in management. • Encourage surrounding land managers to do the same.

  • About Pigs [PDF]
    May 2015 About Pigs Pigs are highly intelligent, social animals, displaying elaborate maternal, communicative, and affiliative behavior. Wild and feral pigs inhabit wide tracts of the southern and mid-western United States, where they thrive in a variety of habitats. They form matriarchal social groups, sleep in communal nests, and maintain close family bonds into adulthood. Science has helped shed light on the depths of the remarkable cognitive abilities of pigs, and fosters a greater appreciation for these often maligned and misunderstood animals. Background Pigs—also called swine or hogs—belong to the Suidae family1 and along with cattle, sheep, goats, camels, deer, giraffes, and hippopotamuses, are part of the order Artiodactyla, or even-toed ungulates.2 Domesticated pigs are descendants of the wild boar (Sus scrofa),3,4 which originally ranged through North Africa, Asia and Europe.5 Pigs were first domesticated approximately 9,000 years ago.6 The wild boar became extinct in Britain in the 17th century as a result of hunting and habitat destruction, but they have since been reintroduced.7,8 Feral pigs (domesticated animals who have returned to a wild state) are now found worldwide in temperate and tropical regions such as Australia, New Zealand, and Indonesia and on island nations, 9 such as Hawaii.10 True wild pigs are not native to the New World.11 When Christopher Columbus landed in Cuba in 1493, he brought the first domestic pigs—pigs who subsequently spread throughout the Spanish West Indies (Caribbean).12 In 1539, Spanish explorers brought pigs to the mainland when they settled in Florida.

  • About the Symbolism and Message of the Mosaic on the Floor of the Refectory of the Episcopal Residence
    About the Symbolism and Message of the Mosaic on the Floor of the Refectory Of The Episcopal Residence Anica Gorgievska NI Institute and Museum – Bitola [email protected] Keywords: the mosaics of Heraclea Lyncestis; art; symbolism, message. Among the many other mosaics in Heraclea, the mosaic on the floor of the room with the apse, the so called refectory of the Episcopal residence, dated from the second half of the VI Century, is also very impressive. This room, which covers a surface of around 100 m2, has a rectangular section which on the east side ends with an apse - semicircular on the inside and rectangular on the outside. 1 The mosaic in the apse is geometrical and consists of a semicircular zone with a so called “fish bone” decoration in a frame shaped as a rope, while the aisle mosaic is figural. The composition in the aisle consists of a rectangular zone and three frame zones. The rectangular zone is divided into four rectangular parts, which are also divided. This time the issue of our presentation is not the exploration of the most famous mosaic presentations of the deer, doe, lion, bull, cheetah, fish, dolphin but of those less known but none the less challenging. It is a general conclusion that in the seemingly chaotic presentation of this composition there is in fact a perfect order. Nothing is accidental. Observing field by field, turning over and reading each composition of the Christian Universe, we conclude that the field pairs gradually move forward and upward. What is at the beginning is also at the end, and vice versa.

  • Government Data Confirm That Grizzly Bears Have a Negligible Effect on U.S. Cattle and Sheep Industries
    Government data confirm that grizzly bears have a negligible effect on U.S. cattle and sheep industries In the United States, data show that grizzly bears (Ursus arctos) kill few cattle and sheep. Livestock predation data collected by various governmental bodies differ significantly, however. The most recent data published by the U.S. Department of Agriculture-Animal and Plant Health Inspection Service (USDA)1 indicate losses many times greater than those collected by states and the U.S. Fish and Wildlife Service (FWS). For instance, the USDA claims grizzly bears killed 3,162 cattle in nine states (in 2015), while the FWS verified only 123 such losses in three states (in 2013). Montana’s Board of Livestock’s data show that between 2015 and 2018 cattle losses from grizzly bears numbered 61 or less annually. The USDA’s methodology involves collecting data from a few mostly unverified sources, which the USDA then extrapolated statewide without calculating standard errors or using models to test relationships among various mortality factors.2 This contravenes the scientific method and results in exaggerated livestock losses attributed to native carnivores and dogs. Unfortunately, this misinformation informs public policies that harm native carnivores, including countless legislative attacks on grizzly bears, wolves and the Endangered Species Act. The Humane Society of the United States analyzed the USDA’s embellished predation numbers. Their data show that farmers and ranchers lose nine times more cattle and sheep to health, weather, birthing and theft problems than to all predators combined. In the USDA reports, “predators” include mammalian carnivores (e.g., cougars, wolves and bears), avian carnivores (e.g., eagles and hawks) and domestic dogs.

McMAHAN,Texas Parksand Wildlife Department,Hunt Abstract: To observe forage competition between deer and livestock, the forage selections of a tame deer (Odocoileus virginianus), a goat, a sheep, and a cow were observed under four range conditions, using both stocked and unstocked experimental pastures, on the Kerr Wildlife Management Area in the Edwards Plateau region of Texas in 1959. The animals were trained in 2 months of preliminary testing. The technique employed consisted of recording the number of bites taken of each plant species by each animal during a 45-minute grazing period in each pasture each week for 1 year.

  • Heraldic Terms
    HERALDIC TERMS The following terms, and their definitions, are used in heraldry. Some terms and practices were used in period real-world heraldry only. Some terms and practices are used in modern real-world heraldry only. Other terms and practices are used in SCA heraldry only. Most are used in both real-world and SCA heraldry. All are presented here as an aid to heraldic research and education. A LA CUISSE, A LA QUISE - at the thigh ABAISED, ABAISSÉ, ABASED - a charge or element depicted lower than its normal position ABATEMENTS - marks of disgrace placed on the shield of an offender of the law. There are extreme few records of such being employed, and then only noted in rolls. (As who would display their device if it had an abatement on it?) ABISME - a minor charge in the center of the shield drawn smaller than usual ABOUTÉ - end to end ABOVE - an ambiguous term which should be avoided in blazon. Generally, two charges one of which is above the other on the field can be blazoned better as "in pale an X and a Y" or "an A and in chief a B". See atop, ensigned. ABYSS - a minor charge in the center of the shield drawn smaller than usual ACCOLLÉ - (1) two shields side-by-side, sometimes united by their bottom tips overlapping or being connected to each other by their sides; (2) an animal with a crown, collar or other item around its neck; (3) keys, weapons or other implements placed saltirewise behind the shield in a heraldic display.

  • The Romance of Clan Crests and Mottoes
    For Private Circulation The Romance of Clan Crests and Mottoes BY A. POLSON, F.S.A., Scot. H./v . 4/^. )12f Ht 4^ J ^X^ ^ m^-t JfiUum,— The Romance of Clan Crests and Mottoes. This is not a paper on Heraldry, but only a small collec- tion of legends regarding the incidents which are said to account for the crests and mottoes of some of the Highland clans. It is hoped that the recital of these may induce some of the members of the clans not mentioned here to tell any story they may have heard regarding their crests, so that fellow clansmen may take a deeper interest in all that pertains to the crest which many of them so proudly wear. The innate vanity which has prompted men of all races and ages to don ornaments and decorations must, among other things, be held responsible for the armorial bearings which have been, and are, worn by individuals, families, and communities, all of whom seem peculiarly sensitive as to the right of any other to impinge on their privilege of wearing the peculiar design chosen by themselves or an ancestor. Heraldry is not itself an old science, but the desire for some distinguishing ornament accounts, among savages, for the painted designs their bodies and on their shields and on ; men bearing similar designs were, and are, regarded as brethren. There is ample evidence of the antiquity of these emblems. One wonders whether Jacob in blessing his sons had in mind the emblems of the tribes when he said: " Judah is a lion's whelp.

  • Ruminant Animal? Many Different Species of Ruminant Animals Are Found Around the World
    What is a Ruminant Animal? Many different species of ruminant animals are found around the world. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre. The rumen is filled with billions of tiny microorganisms that are able to break down grass and other coarse vegetation that animals with one stomach (including humans, chickens and pigs) cannot digest. Ruminant animals do not completely chew the grass or vegetation they eat. The partially chewed grass goes into the large rumen where it is stored and broken down into balls of “cud”. When the animal has eaten its fill it will rest and “chew its cud”. The cud is then swallowed once again where it will pass into the next three compartments—the reticulum, the omasum and the true stomach, the abomasum. Dairy calves have a four-part stomach when they are born. However, they function primarily as a monogastric (simple-stomached) animal during the first part of their lives. At birth the first three compartments of a calf’s stomach—rumen, reticulum, and omasum—are inactive and undeveloped. As the calf grows and begins to eat a variety of feeds, its stomach compartments also begin to grow and change. The abomasum constitutes nearly 60 percent of the young calf’s stomach, decreasing to about 8 percent in the mature cow. The rumen comprises about 25 percent of the young calf’s stomach, increasing to 80 percent in the mature cow.

  • SYMBOLISM of the SERPENT in KLIMT's DRAWINGS Antonela
    SECTION: LANGUAGE AND DISCOURSE LDMD 2 SYMBOLISM OF THE SERPENT IN KLIMT’S DRAWINGS Antonela Corban, PhD. “Al. I. Cuza” University of Iaşi and University of Burgundy, Dijon Abstract. The theme of the serpent repeats and undergoes constant reinterpretation in many of Klimt’s paintings, the author often considering the significance conferred to it by tradition, yet adding personal elements as well in its pictorial approach. The purpose of this article is to indicate and analyze the very paintings in which Klimt treats the theme of the snake from the perspective of its potential significations. To start with, we shall focus on the analysis of the signification of the snake/ serpent symbol in various cultural and religious areas and we shall insist on the ambivalent character of this symbol (the serpent could be associated with both life and death, being a creature that triggers both fear and fascination). Out of the many interpretations associated with the symbolic myth of the serpent, we shall choose only those related to Klimt’s work, noticing that the artist copes, each and every time, with a different signification of it. A first meaning the painter considers is that of creative wisdom, based on intelligence, knowledge and power – Asclepius’s serpent (in Medicine and Hygeia) or Athens’ serpent (Pallas Athene). On the other hand, it may represent the poisonous intelligence associated with cunning and envy, as in Jurisprudence, in Envy or his late, unfinished work, Adam and Eve. It could be about the complex embodiment of natural forces (benevolent, as the dragon from Tragedy, or hostile, as the Echidna – like monster, together with Typhon, the winged one, in Beethoven Frieze).
