Looking for volunteer flocks from Manitoba for a parasite resistance study!


In the upcoming summer of 2018, the researchers are looking to continue and survey more flocks in Manitoba - this will be the 4th year of the study. The project will look at parasite burden and at the efficacy of treatment at the flock level. Molecular techniques for identification of parasites will be used. Detection of parasite resistance to dewormers and its evolution will be monitored over several years. 
If your flock consist of 20 or more ewes and you are interested in this project, we would like you to contact us (information at right). The results are confidential. However if you want to share the results with your regular veterinarian, we will ask for your consent and will forward the results to her/him\

Over the past few years, a team of investigators as well as summer research students from the University of   Calgary,   Faculty   of   Veterinary Medicine have undertaken surveys of sheep flocks in Western Canada (including Manitoba) to assess the level of gastro-intestinal parasites present. The researchers conducted more detailed investigation on parasite resistance to dewormers on a number of farms in Alberta by on-farm visits to perform fecal egg count reduction tests. The results of this work suggests that many Alberta sheep flocks have high parasite burdens and that Ivomec and Safeguard/Valbazen resistant parasites may be more common than previously thought in Alberta and probably Western Canada.

Effects of CIDR/PMSG Programs on Lambing Rate

Objective: To compare the hormonal/ ovarian responses and pregnancy/ lambing rates of ewes treated with CIDR®-estrogen-Folligon® or CIDR®-Folligon® out of the breeding season.

Project Date: 2012


Manipulating Day Length for Out of Season Breeding

A two-year-long study, funded by ARDI, took place in Manitoba examined whether artificial changes in daylight can result in out-of-season lamb production through off-season breeding. These results are based on one flock of commercial dorset cross ewes. The reason that we do research is with the expectation of success. However, results in this study show that some ewes did respond to photoperiod but not enough to be feasible.
Project Date: 2012 - 2013
