“…In that study, a significant effect on weight gain for treatment AH was seen for all three years, but for AC treatment only in one, although the mean infestations in the control animals were 102, 326 and 180 hornflies/animal per year (Sanson et al, 2003). Seifert (1971) and Turner and Short (1972) studied European crosses Hereford×Shorthorn (HS) and F3 crossbreds Afrikander× Hereford× Shorthorn (AX) and Brahman×Hereford×Shorthorn (BX), all naturally infested with gastrointestinal nematodes and ticks, treated with a suppressive regime every 21 days for both types of parasite for one year after weaning.…”

Endo- and ectoparasite infections are among the most important causes of disease and production losses in beef cattle in tropical and subtropical regions. Nevertheless, most treatments are given without epidemiological information and without evaluating their effect on the development of the animals. In this work we present the results of a study of the effect of treatments against endo- and ectoparasites in crossbred steers, during three cycles of field trials in the Brazilian Cerrado region. Three anthelmintic treatments during the winter and three acaricidal treatments during the spring/summer provided significant additional weight gain in three and two experimental trials, respectively. In the trials, steers treated for gastrointestinal nematodes gained a mean of 33 kg more and those treated for ectoparasites had additional mean weight gains of 13 kg compared with non-treated steers.

“…The effect of the Cypermethrin on fly populations has been previously studied [12][13][14], however in this trial there was no negative control group. This was due to the ethical considerations of having to leave a group of animals deliberately unprotected, especially as the farm had a history of high levels of disease.…”

“…Pour-on preparations are applied to the animal's skin along its back repeated every four to six weeks and fly tags are applied to the ear the same way as an identification ear tag and slowly release the substance over time. Both have been trialled to varying successes but have not been directly compared against each other [12][13][14]; in particular, there is no recent trial work into the effectiveness of these tags in the UK.…”

Infectious bovine keratoconjunctivitis (IBK) caused by Moraxella bovis is commonly seen in the summer months spread by face flies. This trial investigated the difference in incidence of IBK cases from natural exposure between two groups of animals, one treated with Cypermethrin pour-on preparation (PON, n = 98) and one with Cypermethrin impregnated ear tags (TAG, n = 99). Daily Live Weight Gain (DLWG) difference was investigated between animals with cases and those without and between treatment groups. A randomised positive control study, enrolled 197 animals split into two treatment groups. Cases of IBK and DLWG were recorded over the grazing season (April–November 2018). Fifty-four cases of IBK were recorded. There was no association between the two treatment groups (p = 0.362) and case status. Breed and under 12 months old were significant factors for having a case; (OR 2.3, p = 0.014 and OR 3.5, p < 0.001 respectively). There was no difference in DLWG between animals that had a case and animals that had not (p = 0.739) or between the two treatment groups (p = 0.215). Based on our results, there is no significant difference between PON or TAG preparations in the prevention of IBK. Younger animals and white-faced breeds are significantly more likely to suffer with IBK.

“…However, reports are conflicting and there are inconsistencies in the quantification of horn fly damage. Studies on cow–calf systems, which were either untreated or treated for control of horn flies, have demonstrated minimal increases in weaning weights or no increase at all (Schreiber et al , 1987; Sanson et al , 2003), even when infestation levels were above the economic threshold (Hogsette et al , 1991; Foil & Hogsette, 1994). By contrast, other studies have reported significant weight differences, thereby demonstrating weight‐increasing advantages of treatments for cow–calf pairs (Campbell, 1976; Quisenberry & Strohbehn, 1984; Haufe, 1986b) and growing cattle (Harvey & Brethour, 1979; Haufe, 1982; Kunz et al , 1984; De Rouen et al , 2003).…”

. The horn fly, Haematobia irritans (Linnaeus 1758) (Diptera: Muscidae) is one of the most widespread and economically important pests of cattle. Although insecticides have been used for fly control, success has been limited because of the development of insecticide resistance in all countries where the horn fly is found. This problem, along with public pressure for insecticide-free food and the prohibitive cost of developing new classes of compounds, has driven the investigation of alternative control methods that minimize or avoid the use of insecticides. This review provides details of the economic impact of horn flies, existing insecticides used for horn fly control and resistance mechanisms. Current research on new methods of horn fly control based on resistant cattle selection, semiochemicals, biological control and vaccines is also discussed.
