(ten,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

You will find a light amount of investigation on literature towards tick load for the cows getting warm regions in the Americas. Really education on this subject matter was basically done in subtropical regions instance South Africa [8, 15], nations having extreme highest temperature such Egypt and Pakistan , and some tropical regions including Tanzania and you may Nigeria . Tick burden often is claimed using transformed data, that makes results assessment to own actual tick burden difficult to translate. This study suggests the true tick burden and its own relationship with heat fret indicator inside four Bos taurus breeds based in about three different geographic aspects of Colombia (the new Caribbean, Andean and you may Orinoquia places). Tick weight during these Colombian cattle breeds was lower than one found in a research having fun with steers grazing regarding the Meta service (Orinoquia area). Additionally, an average tick weight based in the four Colombian types during the our very own try out (17.4 ± 24.6) is leaner than just one to noticed in most other tropical countries such as for instance the fresh new B. indicus Meru crossbred when you look at the Tanzania (37.5 ± 11.8) and lots of B. indicus cows populations (Light Fulani and you may Bunaji types and their crossbreds) in the Nigeria (twenty-two ± step one.4) . The many cows breeds, lawn species, grazing government, herding system, weather and you can environmental regions of presses you will explain the high tick burden utilized in these types of other degree.
Tick shipments towards the cows government
The brand new tick weight with the rump and you can end from SM (seven.2 ± twelve.2), ROMO (5.8 ± 10.2) and CCC (nine.cuatro ± 15.1) cattle try higher than the fresh new tick burden located on the butt foot, tummy and you can flanks (step one.0 ± dos.cuatro, 4.six ± six.nine and eight.dos ± eleven.step one, respectively). These efficiency accept men and women received by within the Nguni cattle. These experts discovered that the brand new tick burden towards the end and you will perineum try higher araЕџtirmak iМ‡Г§iМ‡n tiklayin than the fresh tick burden for the tummy regarding the season. A low tick weight within the BON, ROMO and CCC cattle was observed towards the lead and you may shoulder with the back and you may loin. Furthermore, Asmaa et al. learned that a decreased quantity of clicks was indeed noticed within the vision, shoulder and you can boobs. Clicks choose undetectable and you can enjoying anatomical areas toward animal body . And this, a suitable environment to possess tick emergency is actually under the end and perineum, perhaps detailing the new lot out of presses seen within these system areas. Simultaneously, the trunk base, udder, belly, fore and bottom flank much more confronted by grass, and this with ease attained because of the presses. This will be precisely why i observed a high ratio of the complete tick load on these body areas.
Different kinds of lawn and you may paddocks where this type of dogs offer you will bring about differences in tick load because of the anatomical zones. This is substantiated by the equivalent part of tick burden by the anatomical zones noticed towards the ROMO and you will CCC breeds, that have been located at a similar experimental channel and you may was basically provided with the exact same kind of grass. Having said that, the brand new tick burden of the anatomical zone is very additional inside BON and you may SM breeds, in fact it is simply told me from the another environment.
Sex, many years and real time lbs
The greater tick load noticed in females agrees with the outcomes regarding Rehman mais aussi al. from inside the Pakistani cows, where ladies got a significantly higher tick burden than guys. Likewise, there was a high frequency off tick infestation in women (58.7%) compared to guys (41.5%) from inside the Egyptian cattle . At the same time, no significant distinctions had been found into infestation frequency away from R. microplus ranging from males and females inside Indian cattle and you will Mexican cattle . Regarding experimental stations where the cattle in regards to our study had been kept, bulls received preferential government simply because they got asleep attacks till the beginning of the 2nd reproduction seasons, and you may had been allocated inside paddocks having less equipping rate. On the other hand, cows were always leftover in the high stocking rates. These particular requirements gotten of the bulls throughout certain weeks of your own seasons you are going to explain why we found a lesser tick burden in men compared to lady within studies.
