(10,1528) = 5.11, P Table 5 Overall tick burden and tick burden by categories of the temperature-humidity index (means ± standard errors) in four Colombian cattle breeds
Conversation
There was a scant level of investigation regarding the books toward tick weight for the cattle to have exotic places regarding the Americas. Extremely training with this question have been carried out in subtropical countries such as for instance Southern area Africa [8, 15], places that have high higher heat eg Egypt and you may Pakistan , and some exotic places instance Tanzania and you will Nigeria . Tick load kissbrides.com Г¶nemli kГ¶prГј can often be claimed having fun with switched investigation, that renders result research to have real tick burden hard to understand. This research shows the real tick load and its own relationship with temperature worry indicator inside the five Bos taurus breeds based in three other geographical regions of Colombia (brand new Caribbean, Andean and you can Orinoquia nations). Tick burden on these Colombian cattle breeds is lower than one to included in a research having fun with steers grazing about Meta institution (Orinoquia area). At the same time, an average tick weight based in the five Colombian types from inside the the check out (17.4 ± 24.6) is leaner than just one to present in most other warm places particularly the brand new B. indicus Meru crossbred inside Tanzania (37.5 ± eleven.8) and several B. indicus cows communities (White Fulani and you can Bunaji types in addition to their crossbreds) within the Nigeria (twenty-two ± step 1.4) . The various cattle breeds, yard variety, grazing administration, herding program, weather conditions and you will environmental aspects of ticks you’ll give an explanation for high tick burden included in these most other education.
Tick delivery on cows government
The tick weight towards the rump and you will tail out-of SM (7.dos ± twelve.2), ROMO (5.8 ± 10.2) and you will CCC (nine.cuatro ± 15.1) cows are higher than the latest tick weight found on the butt base, belly and you can flanks (step 1.0 ± 2.4, cuatro.six ± 6.9 and you may seven.2 ± eleven.step 1, respectively). Such results trust those individuals received from the in the Nguni cattle. These people found that this new tick load with the tail and you will perineum was more than this new tick burden on belly in the season. A low tick load inside the BON, ROMO and you can CCC cattle was seen into lead and shoulder followed by the trunk and you will loin. Similarly, Asmaa et al. learned that the lowest number of presses have been noticed within attention, shoulder and you may tits. Ticks prefer undetectable and you will warm anatomical zones to the creature looks . Which, the ideal environment to own tick emergency try within the tail and you can perineum, maybe outlining the latest high number away from presses seen in these human body zones. At the same time, the rear feet, udder, stomach, fore and bottom flank be much more met with lawn, and therefore with ease attained of the clicks. This will be exactly why we seen a top proportion of your full tick burden in these human anatomy zones.
Different varieties of turf and you may paddocks in which this type of pets feed you will definitely cause differences in tick load by anatomical zones. This really is substantiated of the comparable part of tick load by the anatomical areas seen to your ROMO and you will CCC breeds, that happen to be located at a comparable experimental route and was indeed fed with the exact same variety of lawn. Conversely, the latest tick weight of the anatomical zone is really more into the BON and you may SM types, and is partly informed me because of the a different sort of ecosystem.
Sex, years and live weight
The better tick load noticed in women agrees with the results regarding Rehman ainsi que al. within the Pakistani cows, in which ladies got a dramatically highest tick burden than males. At the same time, there was a top frequency off tick infestation in women (58.7%) than in men (41.5%) from inside the Egyptian cattle . Likewise, zero tall differences have been located to the infestation incidence regarding Roentgen. microplus ranging from women and men in the Indian cows and you may Mexican cows . From the fresh stations where cattle for the research was in fact leftover, bulls received preferential government simply because they had asleep symptoms through to the beginning of the next breeding season, and you will was basically assigned in paddocks that have a lowered equipping rates. Conversely, cattle was basically always leftover in the high equipping pricing. These conditions gotten by bulls while in the certain days of one’s year you will define why we located a lower tick load within the guys as compared to female within study.
