(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
Discussion
Discover a light quantity of analysis about books with the tick load inside cattle getting exotic places on the Americas. Extremely degree on this topic was carried out in subtropical nations for example Southern Africa [8, 15], countries that have significant highest temperature particularly Egypt and you will Pakistan , and some tropical countries eg Tanzania and you can Nigeria . Tick burden is oftentimes reported having fun with transformed studies, that produces impact evaluation to possess actual tick load hard to translate. This study shows the genuine tick load and its reference to temperature fret indicator during the five Bos taurus types located in around three more geographical aspects of Colombia (brand new Caribbean, Andean and you may Orinoquia regions). Tick load on these Colombian cows types are below you to definitely included in an experiment using steers grazing on Meta company (Orinoquia region). Additionally, the average tick weight found in the four Colombian Pakistan gelin fiyatД± types for the our very own try out (17.4 ± 24.6) is gloomier than that observed in most other exotic countries instance the fresh new B. indicus Meru crossbred for the Tanzania (37.5 ± 11.8) and many B. indicus cows populations (Light Fulani and you may Bunaji types and their crossbreds) inside the Nigeria (22 ± 1.4) . The many cows types, turf varieties, grazing administration, herding program, climate and you can environmental aspects of presses might give an explanation for highest tick burden utilized in such other studies.
Tick shipping on the cattle government
The fresh tick weight towards rump and you can tail out of SM (7.2 ± a dozen.2), ROMO (5.8 ± ten.2) and you may CCC (nine.cuatro ± fifteen.1) cattle is actually more than brand new tick load on the butt base, tummy and you will flanks (1.0 ± dos.cuatro, 4.six ± six.nine and you may 7.dos ± eleven.step one, respectively). These types of results accept those people acquired because of the in Nguni cattle. Such authors found that the fresh new tick burden into the tail and you will perineum was greater than the fresh new tick weight to your stomach in the 12 months. A decreased tick burden in the BON, ROMO and you will CCC cattle is seen to the head and you can neck followed closely by the rear and you will loin. Furthermore, Asmaa mais aussi al. unearthed that a decreased amount of presses was in fact observed in the attention, shoulder and you can chest. Clicks favor invisible and you will warm anatomical zones for the creature human anatomy . Which, an appropriate ecosystem for tick emergency is in tail and you may perineum, possibly describing the latest large number regarding clicks observed throughout these human body zones. On top of that, the back foot, udder, belly, fore and you will bottom flank be confronted with lawn, hence with ease achieved from the presses. This is the reason why i seen a top proportion of your own total tick load throughout these human anatomy areas.
Different kinds of turf and you can paddocks where these types of animals feed you certainly will end in variations in tick burden by anatomical areas. This will be corroborated of the similar part of tick burden by the anatomical zones seen to your ROMO and you will CCC types, which have been found at a comparable fresh route and you can were provided with the exact same form of turf. However, the newest tick burden from the anatomical region is really additional inside BON and SM types, which is in part told me by a special environment.
Sex, many years and alive weight
The greater tick burden present in females will abide by the results out-of Rehman et al. inside Pakistani cows, in which lady got a significantly highest tick load than just guys. On the other hand, you will find a higher incidence of tick infestation in women (58.7%) than in men (41.5%) during the Egyptian cows . Likewise, zero extreme differences was basically located for the infestation frequency out-of Roentgen. microplus between people when you look at the Indian cows and North american country cattle . Regarding the fresh stations where in fact the cows for the investigation had been kept, bulls received preferential management because they had sleep attacks till the start of second reproduction 12 months, and you may had been allocated when you look at the paddocks that have less stocking rates. Alternatively, cattle was constantly kept at the large stocking costs. That these requirements obtained by bulls during the specific days of your own 12 months you are going to explain why we discover a lower tick weight inside the males compared to ladies within research.
