“…High R. appendiculatus counts were observed on individual animals among both breeds implying that a few individual animals among both breeds had low resistance to this tick species and were experiencing a resistance breakdown to R. appendiculatus. Such a phenomenon has been reported (Dipeolu et al 1992) and is responsible for why such indigenous African breeds still carry large numbers of ticks even when they are exposed to ticks for a long time (Dossa et al 1996) Mean counts of R. (Boophilus) decoloratus ticks were moderate in number on both the Nkedi Zebu and Ankole cattle and were lower than those of R. appendiculatus on either breed. Both host and external factors influenced R. (Latif et al 1991b).…”

A cross-sectional study was conducted in Soroti district of Uganda to establish important traits of Nkedi Zebu and Ankole cattle regarding their production performance responses to natural infections of trypanosomes, gastrointestinal nematodes, Theileria parva, Babesia bigemina, Anaplasma marginale and tick infestations. Over four visits between October 2006 to August 2007, tick counts were performed and blood, faecal samples and sera were collected from the Nkedi Zebu (295) and Ankole (165) cattle from 86 herds in six locations per visit. Low parasitological prevalence of trypanosome infection (<6%) and high prevalence of gastrointestinal nematode infections (>30%) with low faecal egg counts (110-300 eggs per gramme (EPG)) were observed in the Nkedi Zebu and Ankole cattle. Both breeds had high, moderate and low mean counts of Rhipicephalus appendiculatus (18.0-24.0), Rhipecephalus (Boophilus) decoloratus (3.6-10.3) and Amblyomma variegatum ticks (1.7-4.3), respectively. In addition, both breeds had similar mean packed cell volumes (26.4-31.2) and a similar percentage of animals were anaemic (14.5-36.6%). The Nkedi Zebu cattle further had higher mean optical density (OD) values for antibodies against T. parva (1.093-1.445) and A. marginale infections (0.573-0.583), and significantly (P < 0.001) higher mean OD values of antibodies against B. bigemina infections (1.07-2.175) than the Ankole cattle: T. parva (1.030-1.302); A. marginale (0.442-0.603) and B. bigemina infections (0.863-2.154). The Ankole cows produced significantly more (P < 0.001) milk per day (2.68 L) than the Nkedi Zebu cows (1.98 L), and the Ankole oxen had significantly higher (P < 0.05) draught power output (2.57 days/acre) than the Nkedi Zebu oxen (2.93 days/acre). Liveweights of calves aged 0-12 months of both breeds were comparable, suggesting that the Nkedi Zebu and Ankole cattle under similar disease challenge exhibited similar growth rates. In conclusion, the Nkedi Zebu cattle seem to possess a higher degree of disease resistance against endemic parasitic diseases, while the Ankole cattle seem to possess a moderate degree of disease resistance coupled with a moderate production potential.

“…Rabbits were kept in small animal house and goats in animal pens but were released to graze outside daily for 2 to 3 h as explained elsewhere in this paper. The brown ear tick, R. appendiculatus, were reared on New Zealand white rabbits kept in metal cages as described by Dossa et al (1996) and Solomon and Kaaya (1998). The rabbits were given rabbit pellets and water (ad libitum).…”

brown ear tick, Rhipicephalus appendiculatus, the vector for Theileria parva. Neem oil was applied on rabbit ears using a fine brush, whereas NSP was mixed with rabbit pellets at various concentrations and fed on goats on which various instars of the tick were allowed to feed. Tick larvae smeared with Neem oil (NO) while attached to rabbit ears exhibited significant mortalities. The 10% NO induced a mortality of 40% compared to less than 1% observed in Peanut oil (PO) control. Furthermore, engorgement weights were significantly reduced (0.1 mg NO vs 4 mg PO). Their corresponding moulting percentages were 1 and 71% in NO and PO, respectively. Adult female ticks exhibited reduced engorgement weights and egg mass. Larvae able to attach on goats maintained on 100% NSP were only 11% compared to 66% for control goats fed on rabbit pellets (RP). The corresponding nymphal attachments were 24% NSP and 79% RP. The number and weights of eggs produced by adult ticks fed on goats maintained on NSP also dropped significantly. The hatchability of eggs produced by these ticks was also significantly reduced.

“…The results obtained by Piper et al [ 10 ] on ticks confirm that the expression of certain genes in the skin of bovines reduces the infestation of the tick of the cattle R. microplus . Other studies show that cattle Bos indicus have developed resistance against Amblyomma variegatum [ 11 ]. In any case, the selection of tick-resistant animals can reduce the devastating effect of tick infestation.…”

A study was carried out on the Opkara (Benin) cattle farm on 64 cattle of four different breeds (16 individuals per breed) from June to December 2016. During this study, three tick species were found in different numbers, Amblyomma variegatum (732), Rhipicephalus microplus (8079), and Hyalomma spp. (208), with parasitic intensity of 11.90, 126.23, and 3.25, respectively. The interracial comparison of the tick infestation between the cattle showed a significant difference (P < 0.001). However, Girolando was more infested than all the cattle breeds. Infestation of A. variegatum, R. microplus, and Hyalomma spp. on the Girolando was, respectively, 19.43 ± 2.71, 171.25 ± 23.50, and 7.12 ± 0.63, but the Borgou were less infested. Borgou breed females were more infested by A. variegatum (4.41 ± 1.14) than females Girolando (4.20 ± 0.90). The Crossbred and Azawak females were less infested (P < 0.01). The mean of A. variegatum on Borgou, Azawak, Crossbred, and Girolando calves was 1.29 ± 0.35, 0.66 ± 0.26, 1.37 ± 0.37, and 2.25 ± 0.48 (P < 0.01), respectively. The results of this study can be exploited to include genetic and nongenetic approaches to tick control.
