(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
Talk
There’s a scant quantity of data regarding the literary works into the tick load within the cattle for exotic regions regarding Americas. Very knowledge about this thing was in fact carried out in subtropical countries instance Southern Africa [8, 15], regions with significant higher temperature for example Egypt and you will Pakistan , and several exotic countries such as for instance Tanzania and you will Nigeria . Tick load is oftentimes advertised playing with switched investigation, that renders effect testing getting actual tick weight difficult to translate. This study shows the true tick load and its own reference to temperatures stress indices inside five Bos taurus breeds based in three different geographic regions of Colombia (the new Caribbean, Andean and you can Orinoquia countries). Tick load on these Colombian cattle breeds is actually less than one found in a research using steers grazing from the Meta service (Orinoquia region). Likewise, an average tick weight found in the five Colombian types inside the our very own experiment (17.4 ± 24.6) is gloomier than just you to seen in almost every other tropical nations for example the newest B. indicus Meru crossbred from inside the Tanzania (37.5 ± eleven.8) and many B. indicus cattle populations (White Fulani and Bunaji breeds as well as their gГјzel Panama kД±zlar sД±cak crossbreds) from inside the Nigeria (22 ± step 1.4) . The different cattle breeds, lawn species, grazing administration, herding system, weather and you may ecological regions of ticks you’ll explain the highest tick load utilized in this type of most other studies.
Tick distribution towards the cows authorities
The fresh new tick load into rump and you can end out of SM (7.2 ± twelve.2), ROMO (5.8 ± ten.2) and you will CCC (9.4 ± fifteen.1) cattle is higher than the new tick weight found on the rear legs, tummy and you may flanks (step 1.0 ± 2.cuatro, cuatro.six ± six.nine and you can 7.dos ± 11.1, respectively). These performance trust those individuals gotten from the when you look at the Nguni cattle. This type of experts discovered that this new tick load for the end and you will perineum is actually more than the fresh new tick burden towards the belly on the seasons. A low tick burden inside BON, ROMO and you may CCC cattle is actually observed to your direct and you may neck followed closely by the rear and you will loin. Also, Asmaa et al. unearthed that a decreased number of ticks was seen within attention, shoulder and you can bust. Clicks favor hidden and warm anatomical areas on creature body . And that, a suitable environment having tick success is according to the tail and you will perineum, maybe explaining brand new large number away from ticks noticed during these muscles areas. Additionally, the rear legs, udder, belly, fore and you may bottom flank be much more confronted by lawn, and therefore effortlessly attained from the presses. This is exactly why we observed a leading proportion of your overall tick burden in these human anatomy zones.
Different varieties of lawn and you may paddocks in which these types of pets provide you may bring about variations in tick load from the anatomical zones. This can be corroborated by similar part of tick load because of the anatomical areas observed on ROMO and you will CCC types, which were located at an equivalent experimental channel and you may was indeed provided with the exact same types of lawn. Conversely, the fresh new tick load by the anatomical region is extremely some other in the BON and SM breeds, that’s partly informed me from the a separate ecosystem.
Sex, age and you may alive lbs
The greater tick load seen in women will abide by the results out-of Rehman et al. when you look at the Pakistani cows, in which females got a substantially highest tick load than simply males. Additionally, there is certainly a top incidence away from tick infestation in women (58.7%) than in men (41.5%) within the Egyptian cattle . In addition, zero high differences were discovered towards the infestation incidence away from Roentgen. microplus anywhere between people inside Indian cows and you can North american country cattle . On the fresh channels where in actuality the cattle for the studies was indeed left, bulls gotten preferential management since they got sleeping attacks through to the beginning of the next breeding year, and you may were assigned inside paddocks that have a lowered equipping rate. In contrast, cattle have been constantly remaining on highest equipping cost. That these conditions obtained because of the bulls throughout the some months of one’s seasons might describe the reason we found less tick load from inside the men than the female inside our research.
