How Far Is Too Far with a Mixed Breeding Program? Jessica Morgan, Agriculture Agent, Anson County
How Far is Too Far with a Mixed Breeding Program? Jessica Morgan, Agriculture Agent, Anson County We’ve all heard the horror stories of purebred dogs and their health problems while mutts seem to live forever. Obviously if you are a purebred breeder, you have an incredible amount of responsibility to uphold the characteristics of a breed. However, if you are a typical commercial cattlemen let’s take a look at how these thoughts can translate to our cattle herds. Why Crossbreed? Crossbred cattle can have some significant advantages over the use of one breed in your cattle. The two main benefits include hybrid vigor as well as combining the best strengths of the various breeds used to form the cross. Hybrid vigor, also known as heterosis, explains the superiority in performance of the crossbred animal compared to the average of the straightbred parents. Hybrid vigor is most noticeable in low heritable traits, such as growth rate, and reproductive efficiency. The most important advantage for crossbreeding is found in the crossbred cow. Maternal heterosis results in improvements in fertility, calf livability, calf weaning weight and cow longevity. Combining strengths between breeds is also an important reason for crossbreeding. For example, British Breeds (Angus & Hereford) are typically high in marbling potential where Continental breeds (Simmental, Charolais, Gelbveih) have offspring that have desirable levels of marbling and yield grade. Knowing the advantages of the breeds before you breed is important. True crossbreeding is a deliberate decision to produce cattle that have a known genetic makeup to pass genetics from parents to produce a calf with desirable characteristics. -
Evaluating the Potential for Species Reintroductions in Canada
Evaluating the Potential for Species Reintroductions in Canada JAY V. GEDIR, TIAN EVEREST, AND AXEL MOEHRENSCHLAGER Centre for Conservation Research, Calgary Zoo, 1300 Zoo Road NE, Calgary, AB, T2E 7V6, Canada, email [email protected] Abstract: Species reintroductions and translocations are increasingly useful conservation tools for restoring endangered populations around the world. We examine ecological and socio- political variables to assess Canada’s potential for future reintroductions. Biologically ideal species would be prolific, terrestrial, herbivorous, behaviorally simple, charismatic, easily tractable, or large enough to carry transmitters for post-release evaluations, and would have small home range requirements. Sociologically, Canada’s large geographic area, low human density, high urban population, widespread protectionist views towards wildlife, and sound economic status should favor reintroduction success. Canada has implemented legislation to safeguard species at risk and, compared to developing countries, possesses substantial funds to support reintroduction efforts. We support the reintroduction guidelines put forth by the World Conservation Union (IUCN) but realize that several challenges regarding these parameters will unfold in Canada’s future. Pressures from the rates of species loss and climate change may precipitate situations where species would need to be reintroduced into areas outside their historic range, subspecific substitutions would be necessary if taxonomically similar individuals are unavailable, -
PLANT BREEDING David Luckett and Gerald Halloran ______
CHAPTER 4 _____________________________________________________________________ PLANT BREEDING David Luckett and Gerald Halloran _____________________________________________________________________ WHAT IS PLANT BREEDING AND WHY DO IT? Plant breeding, or crop genetic improvement, is the production of new, improved crop varieties for use by farmers. The new variety may have higher yield, improved grain quality, increased disease resistance, or be less prone to lodging. Ideally, it will have a new combination of attributes which are significantly better than the varieties already available. The new variety will be a new combination of genes which the plant breeder has put together from those available in the gene pool of that species. It may contain only genes already existing in other varieties of the same crop, or it may contain genes from other distant plant relatives, or genes from unrelated organisms inserted by biotechnological means. The breeder will have employed a range of techniques to produce the new variety. The new gene combination will have been chosen after the breeder first created, and then eliminated, thousands of others of poorer performance. This chapter is concerned with describing some of the more important genetic principles that define how plant breeding occurs and the techniques breeders use. Plant breeding is time-consuming and costly. It typically takes more than ten years for a variety to proceed from the initial breeding stages through to commercial release. An established breeding program with clear aims and reasonable resources will produce a new variety regularly, every couple of years or so. Each variety will be an incremental improvement upon older varieties or may, in rarer circumstances, be a quantum improvement due to some novel gene, the use of some new technique or a response to a new pest or disease. -
January-2021-Newsletter-4
JANUARY NEWSLETTER 2021 MESSAGE FROM OUR BOARD 2020! That’s a wrap! Phew, these final few months have been incredibly busy for our team. Between the Memorial service, markets, Purdy’s Chocolate Fundraiser, Santa Pics, and Grinch Tree fundraisers, the end of 2020 helped us recover from our closure earlier in the year. We brought in large numbers of animals since the start of September and adopted out 34 in the last quarter of the year. In total, we finish the year with 48 total adoptions and 14 animals still in care. Just a week into 2021 we have already brought 17 more cats and kittens into our program and committed to bringing 46 dogs from our partner organization in China at the end of January details below. We hope restrictions will ease this year and allow for more events, but as we navigate these challenges, we continue to adapt and try new ways of creative fundraising. If you are looking to get involved, now is the time. We are going to set up a fundraising committee to help with planning and running events.

Date: ………………………… Signature: ………………………… iii Dissertation summary The African wild dog Lycaon pictus is Africa’s second most endangered carnivore. Only 14 out of 39 countries in Africa still have wild dogs present. This makes the populations of wild dogs in South Africa very valuable with respect to the entire species. Kruger National Park (Kruger) has the only self-sustaining and viable population of wild dogs in South Africa, making Kruger the core area of conservation for South African wild dogs. It is of vital importance to know the numbers of wild dogs present in Kruger. -

Quality Breeder Vs. Backyard Breeders
Swiss Run Greater Swiss Mountain Dogs Quality Breeder vs. Backyard Breeders Try to avoid puppy mills and backyard breeds… We enjoy having a pet in our home are there is nothing wrong with wanting it to be a purebred dog. If there wasn’t a market, puppy mills and backyard breeders wouldn’t be producing puppies. They produce puppies because they can sell them and if they couldn’t sell them, they wouldn’t breed them. The vast majority of dogs should be spayed and neutered and the majority of people do not take the responsibility of breeding seriously. The issue with puppy millers is not that they produce puppies, but that the care and quality involved in the process is lacking and that there is little or no attention to health, temperament or to appropriate home selection. Quality care and quality facilities should be the first step in a breeding program and the puppy millers fall short from the beginning of the process. When profit, current fads and numbers produced become the focus of the breeder rather than the care of the animals and the quality of puppies produced, you end up with poor care, poor conditions, and an overwhelming number of genetically unhealthy and temperamentally unsound dogs. Backyard breeders on the other hand generally have good intention. They generally have a pet they love that is purebred and a reasonable representation of the breed. Through love they either intentionally breed or allow Mother Nature to take its course and the family enjoys raising a litter of puppies and those puppies (assuming they are raised inside and not in the doghouse) are normally well handled and socialized to a normal family household. -
