  3. A Review of on Ectoparasites and Their Cattle Production’ Effect R. L. Byford, M. E. Craig, and B. L. Crosby Department of Entomology, Plant Pathology, and Weed Science, New Mexico State University, Las Cruces 88003 ABSTRACT: Losses in livestock production due to ectoparasite infestations exceed $2.26 billion annually. Over 50 species of ectoparasites infest cattle throughout the United States. The horn fly, Huematobia irrituns CL.1, is the most important and widespread of the five to six major pest species of pastured cattle in the southern region. Results from the examination of production traits from cattle under ectoparasite burdens have been variable, ranging from no effect to significant reductions in weight gains. Because of this inconsistency, specific physiological and nutritional responses in cattle infested or not infested with horn flies have been examined. Data have shown significant differences in nitrogen retention, blood cortisol concentrations, vital signs, water consumption, and urine production. Implications are that total energy balance is altered when an animal is exposed to ectoparasite infestations, thereby resulting in decreased productivity. Key Words: Beef Cattle, Ectoparasites Introduction The U.S. agricultural system is unparalleled in producing food for an increasing world population. Historically, food production has focused on raising grain and legumes (Hodgson, 1976). However, conversion of forage into food for humans by grazing ruminants is an economically important component of food production in the United States. The American Forage and Grassland Council (1974) estimated that there are 400 million hectares of forage-producing land in the United States with an estimated forage value exceeding $10 billion (Sprague, 1974). Throughout the United States, grazing cattle are the basic production units that can best utilize this renewable resource. The mild temperate and subtropical climates of the southern United States combine rich forage resources and long grazing periods that are ideal for beef cattle production. The 1986 USDA Agricultural Statistics show that 35% of the nation’s cattle lJoumal Article X1594, New Mexico Agric. Exp. Sta.

  5. What we tried: At pasture: 2010-2012 Feed through fly control FAIL 2012 pour on permethrin fly control FAIL 2013 dioxin tag rub and phosmet insecticides WIN 2014 phosmet FAIL 2014 spinosad WIN At feedlot: 2013 fly bait WIN 2014 phosmet FAIL 2014 spinosad WIN What failures cost us in 2012- pink eye vet bill over 1500 on 80 cow calf pairs and weaning weights under 450 pounds which may be 40 pounds short. This failure cost us at least 2000 and possible 3000. What the phosmet failure in 2014 cost us- a cow mired due to too much swimming and we lost her : 1900 dollars AND it must have cost us 10 pounds per calf or more. 10 bad days X 1 pound not gained X 69 calves DO NOT FORGET LABOR which totalled 4 hours for two people in two locations for phosmet and spinosad or 16 hours @ 20 to 40 dollars an hour. There were also hours for two of us trying to save the cow. The total cost of this one failure: $ 4190
