Fun Facts Most of Alberta’s sheep farms have crossbred ewes. Crossbreeding combines the traits of two or three different breeds. Crossbreeding also adds what is called hybrid vigour, which helps improve productivity. The main source of income from sheep in Canada is from producing lambs for meat. Wool is a secondary product in most flocks. Sheep dairy is a very small industry in Canada. Lambskin is a by-product of meat processing, and is used in high quality leather goods. Sheep are ruminants that graze and browse. They are able to eat woody plants, weeds, grasses, and grains that humans can’t. They efficiently convert those plant materials into high quality meat, wool, milk, and leather. Flocks of sheep can be used to control vegetation on farms, in cattle grazing areas, and in reforested areas. 1 4-H Sheep Project Guide Level 2 Canadian wool sheep must be shorn once a year. Wool grows continually providing sheep with protection against Canada’s climate. Wool is a valuable fiber that is used for fabrics, clothing, felt, and even insulation. It is a renewable resource. Wool has even been used to clean up oil spills; it can be squeezed out and reused up to eight times. Coyotes are the most common predator of sheep in Alberta. Other predators include foxes, wolves, cougars, bears, and ravens. For more information: www.ablamb.ca Predation Management Module 2014 www.agric.gov.ab (Alberta Agriculture & Forestry) Canadian heritage page Reproduction Purebred, Seed Stock Breeders and Breeding of There are roughly 1,000 breeders of purebred sheep in Canada. Purebred sheep carry Sheep the genetics of one breed, can have registration papers that guarantee the parentage of the animals, and must follow the guidelines of Canada’s Animal Pedigree Act. Random DNA sampling of sheep being registered helps assure pure genetics. Pure breeding sheep means to select and reproduce genetically similar animals. The benefit of having purebred sheep is for more genetic predictability. Selection is based on improving breed quality and economically important traits (growth rate, fertility, mothering ability, feed efficiency, and carcass quality). Purebred sheep, in particular terminal sire rams, are commonly used in commercial

  • Wild Predator Loss Prevention Best Management Practices for Sheep
    Wild Predator Loss Prevention Best Management Practices for Sheep A guide for sheep producers on how to minimize predation of sheep 1 Wild Predator Loss Prevention Best Management Practices for Sheep Producers _______________________________________ ____________________________________________________ What is a Best Management Practice? A Best Management Practice can be a process, activity, method or technique. These processes, activities, methods and techniques are generally understood to be more effective in reaching a certain outcome or accomplishing a task than other conventional processes, activities, methods or techniques. Best Management Practices are used in many professions such as construction, technology, ecological protection, sustainable development and health care. What is a Best Management Practice for Sheep Producers? A Best Management Practice (BMP) is an approach to livestock production that seeks to minimize predation on a flock while taking into account the surrounding environment, including the wild animals within it. A BMP provides sheep producers with a toolkit of options to assist with the protection of livestock from predation. BMPs go with the idea that it is much easier to take steps to prevent predation than to try to stop it once it has started. These are your “best bets” for keeping your livestock safe. These best management practices fall into 5 categories, and are explained in the following pages. They include: ➡Husbandry Practices ➡Predator Repellants ➡Guardian Animals ➡Fencing ➡Knowing Your Neighbours The intent of this BMP is not to limit sheep producers, but rather, to provide options for them. It should be understood that every farm is different, and due to physical factors and geographic location, some farms do not have the option to adapt to several of the suggestions listed in this document.

  • The Use of Alpacas As New-Born Lamb Protectors to Minimise Fox Predation
    Extension Farming Systems Journal volume 1 number 1 – Industry Forum 65 The use of alpacas as new-born lamb protectors to minimise fox predation Sara Mahoney1 and AA Charry2 1 ‘Windara’ Naracoorte SA 5271 2Charles Sturt University, Faculty of Science and Agriculture, Orange NSW 2800 Australia [email protected] Summary. Canine attacks on newborn lambs are a problem for sheep farmers, causing substantial economic losses to the sheep industry. Anecdotal evidence indicates that alpacas reduce the losses caused by such attacks when placed within sheep flocks. A trial was conducted at two sheep farms in rural NSW where experimental – ewes grazing with alpacas - and control – ewes grazing without alpacas – groups, with replication within and across farms were organised with a total of 6,483 breeding ewes. Overall weaning percentages for each flock of sheep were tabulated at 14 weeks and evaluation of performance between groups was conducted using descriptive statistics. An inferential statistical t test for pairs was conducted to find out the level of significance of the difference in performance between the trial and control groups. Combined weaning percentage for the control groups was 69.8% while the experimental groups showed a combined weaning percentage of 82.6%. Assuming equal mortality rate because of natural causes among the groups, it may be concluded that the presence of alpacas within the lambing paddocks increased lambing weaning percentage by 13% with a = 0.025 (i.e. confidence level = 97.5%). The economic benefit is obvious considering that there is an increase of 13 lambs for each 100 breeding ewes that valued at market prices represent a meaningful marginal farm income.

  • Loss of Livestock Including Dairy Animals to Predators – Is It Increasing?
    DAIRY VETERINARY NEWSLETTER March 2011 Loss of Livestock Including Dairy Animals to Predators – Is it Increasing? On March 18, 2011 a settlement was reached between 10 wildlife advocacy groups and the U.S. Department of Interior that would allow hunting for wolves to resume in Montana and Idaho. The settlement still needs approval from U.S. District Judge Donald Molloy in Missoula, Montana. It would keep wolves under federal protection, for now, in Oregon, Washington, Utah and Wyoming. In that entire 6-state Northern Rockies region there are an estimated 1,651 wolves, a population described as expanding rapidly over the last 10 years. A driving force in the decision was increased concern over wolf predation of livestock, as well as wolf-human interactions, subjects on which different groups have conflicting opinions. The exact number of wolves in Utah is unknown, but according to several accounts, incidents of wolves killing livestock are increasing in Utah. Nevertheless, as will be addressed below, it is still true that the vast majority of livestock losses - including losses of dairy animals - to predators are caused by feral dogs and coyotes. An ABC news story from July 2010 quoted Leonard Blackham, Utah Commissioner for Agriculture and Food as saying, "We're very concerned about the wolves coming to Utah - - it's surely a challenge for livestock and livestock producers. They are very aggressive animals. - - "If [a] wolf is in the area [of livestock], the rancher or his employee are legally allowed to take out that animal." The story also mentions a July 2010 incident where “a wolf was taken out in Summit County after killing thousands of dollars worth of livestock”.

  • Guardian Animals for Alberta.Indd
    Alberta Sheep Guardian Animals for Alberta Guardian animals can be very effective along with other appropriate predation control methods. These animals are full-time members of the flock and require patience from livestock owners. Once a guardian animal is able to develop a bond with the livestock they will be able to reach their full protective potential. Guard Dogs The guardian dog is required to protect the flock and is not meant to herd it. A suc- cessful guardian dog is one of genetic quality with an emphasis on proper rearing. Once a puppy has been selected it should be raised among the flock to prevent biting ears, overplaying, and excessive wandering. Quality Characteristics • able to act independently • must be attentive to sheep and not harm them • physically sound and of good conformation • alert, confident, intelligent Selecting the Appropriate Breed Dogs with a history of protecting livestock: • Maremma (Italy) • Shar Planietz (Yugoslavia) • Anatolian shepherd (Turkey) • Komondor (Hungary) • Great Pyrenees (France and Spain) • Akbash (Turkey) How Many Dogs? Experienced dogs may effectively patrol hundreds of sheep within several hundred acres. Younger dogs may not be able to guard as many sheep in such a large area. Topography must also be considered brush, ravines and hills may be too much for one dog. Therefore, once the first dog is well established a second dog may be intro- duced. The established dog can become a role model for an untrained dog. Produc- ers must also be aware of the problems that may arise from introducing more than one dog. If one of the dogs displays inappropriate behaviours, the second dog may also adopt these bad behaviours.
