Project objectives from proposal:
The project will be basically the same at all 4 farms. Each farm will have 30 animals involved in the study, 15 treated and 15 controls. I will go to the sheep and goat farms and work with the farmers to make final adjustments in the arrangements for housing the animals. Deanna Potter will work with David Potter for the beef herd. At approximately four weeks of age, each young animal in the group will have an initial fecal sample taken. They will also be body condition scored. The kids and lambs will be FAMACHA scored. The scoring is done to be sure the animals are not losing condition as a result of the treatment method. The test group will then be given the Regano in their normal ration at a rate of .9gm/100lbs daily. The control group will be kept on a site that has like conditions to the test group, including the population of oocysts.
I will go to each goat and sheep farm to assist with the initial mixing of the treatment ration. I will also go to each farm for the additional fecal collections and scoring.
The primary difference at each farm is related to the life cycle of the Eimeria. It behaves slightly differently in each livestock species. The project is structured to account for this difference. The last fecal at 64 days or 8 weeks will account for a prepatent period of 3 weeks. This will give an indication of the effectiveness of the Regano on any parasite that could have been ingested on pasture. The goats will be fecal sampled on days 0, 20 and 64, sheep at 0, 25 and 64, the calves at 0, 30 and 64.
I will collect the goat and sheep fecal samples and take them to the Diagnostic Laboratory at University of Maine in Orono. Deanna Potter will take the beef samples. Quantitative and qualitative tests will be run.
After all the data is collected the statistical analysis will be done on the results. Effects of treatment and farm will be compared for each animal species by a Repeated Measures Analysis of Variance (ANOVA) where time is the repeated measure, using the PROC GLM module of PC SAS.

It will be done in the late winter and spring of 2009, since the grant will not be received until after the late winter and early spring births of livestock in 2008. The beginning date on each farm will depend on the dates of birth. It will proceed for 8 weeks. After the last fecal exams are done the data will be analyzed within one month and the final report will be written.
How will you disseminate your project results?
An article, available for publication in newsletters will be mailed to each livestock and farming organization in New England including MOFGA, all the NOFA’s, Maine Sheep Breeders Assoc., other state sheep and goat organizations, and state beef organizations.
