Animals from 13 cooperator herds across 7 states were stratified within herd and assigned to 1 of 2 treatments; injectable doramectin (DOR) or injectable extended-release eprinomectin (EPR). There were no differences in pre-weaning cow or calf performance including weight, ADG, reproductive success, or weaning weight. Although EPR cows did have a lower incidence of pinkeye, there were no differences in pinkeye incidence of calves. Fecal samples collected at the start and end of the grazing season indicated a greater reduction in fecal egg counts (FEC) for EPR cows, however, FEC at each timepoint were well below threshold indicative of clinical parasitism. When evaluating feedlot performance, EPR calves tended to have lower incidence of morbidity, however there were no differences in growth performance. When evaluating carcass traits, calves treated with EPR during the pre-weaning phase had a greater marbling score and a greater average quality grade. While there were noted improvements for EPR calves during the feedlot phase including improved morbidity and quality grade, we believe that a lack of parasitic infection during the grazing season may have resulted in a lack of performance differences in this study.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"13 1","pages":"78"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89233502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this engagement has been to empower Kosovars to transform their agricultural sector so that this newly independent country can reduce its reliance on food imports and develop into a food secure nation. Activities conducted under terms of the international memorandum of cooperation and understanding between ISU and the University of Prishtina (UP) are described in this report. Accomplishments resulting from this partnership include: 1) guest lectures by ISU faculty to UP veterinary students, 2) teaching of workshops and courses by ISU faculty to a global population of students enrolled in UP’s International Summer University 2-week educational program, 3) on-farm consultations with Kosovo dairy farmers, 4) establishment of relationships with livestock-oriented associations in Kosovo, and 5) birth of the first-ever bovine embryo transfer calf in Kosovo. These and other on-going activities are heightening awareness of the need to improve agricultural productivity in Kosovo, particularly in the dairy sector, to stop the flow of euros out of the country for purchase of food that could and should be produced within Kosovo.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"74 1","pages":"4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90635723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
