(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
Dialogue
There was a light level of study in the literary works on tick burden into the cattle for tropical places regarding Americas. Most studies about question was basically carried out in subtropical nations including Southern area Africa [8, 15], nations which have extreme large temperature particularly Egypt and you may Pakistan , and lots of exotic places such Tanzania and you will Nigeria . Tick burden is oftentimes stated playing with transformed data, that renders results research to have genuine tick weight tough to translate. This study reveals the genuine tick burden and its own experience of temperatures worry indices within the five Bos taurus breeds situated in three other geographic aspects of Colombia (this new Caribbean, Andean and you will Orinoquia countries). Tick burden during these Colombian cows breeds are lower than you to utilized in a test playing with steers grazing on Meta agency (Orinoquia area). On top of that, the average tick weight based in the four Colombian types for the our very own test (17.cuatro ± 24.6) is lower than that seen in almost every other warm regions such the new B. indicus Meru crossbred during the Tanzania (37.5 ± 11.8) and several B. indicus cows populations (White Fulani and Bunaji types in addition to their crossbreds) from inside the Nigeria (twenty-two ± step one.4) . Different cows breeds, grass variety, grazing administration, herding program, climatic conditions and ecological areas of clicks might explain the large tick weight used in such almost every other degree.
Tick shipments with the cattle government
This new tick weight towards rump and you can tail regarding SM (seven.dos ± twelve.2), ROMO (5.8 ± 10.2) and CCC (nine.4 ± 15.1) cows try greater than the newest tick load on the bottom legs, stomach and you will flanks (1.0 ± 2.4, cuatro.6 ± six.nine and 7.2 ± eleven.1, respectively). These types of results trust those people acquired because of the inside Nguni cows. Such writers found that the new tick load on the tail and you may perineum try higher than the new tick weight into stomach from the year. A low tick weight from inside the BON, ROMO and CCC cows was noticed toward head and you can neck followed closely by the rear and you can loin. Furthermore, Asmaa ainsi que al. learned that a low amount of presses was in fact observed within the sight, shoulder and boobs. Ticks favor undetectable and you will warm anatomical zones towards creature human anatomy . And this, the right ecosystem for tick survival is actually beneath the end and you will perineum, possibly explaining the fresh new high number out of clicks seen in these looks zones. Simultaneously, the trunk legs, udder, stomach, fore and you can rear flank are more exposed to yard, hence effortlessly hit by the clicks. This might be precisely why i noticed a leading proportion of the overall tick burden within these human anatomy areas.
Different varieties of lawn and paddocks in which these types of dogs offer you will produce differences in tick burden because of the anatomical areas. This is certainly corroborated from the similar percentage of tick load by the anatomical zones seen for the ROMO and you will CCC types, which were located at an equivalent fresh station and you will was given with the same particular yard. Conversely, the newest tick load of the anatomical area is really other into the BON and you can SM types, and that is simply informed me of the an alternate environment.
Sex, decades and real time weight
The greater tick burden noticed in women agrees with the outcome from Rehman et al. when you look at the Pakistani cows, in which lady got a dramatically large tick load than simply males. Concurrently, there is a high prevalence of tick infestation in women (58.7%) than in guys (41.5%) in the Egyptian cattle . Likewise, zero extreme variations have been found with the infestation frequency off R. microplus between women and men into the Indian cows and North american country cows . On experimental stations where cattle in regards to our investigation have been kept, bulls gotten preferential administration since they got asleep attacks latinfeels uygulamasД±nД± indir before the beginning of the second breeding 12 months, and you can had been allocated within the paddocks that have a reduced stocking price. On the other hand, cows were usually remaining at the large stocking pricing. These criteria received from the bulls during the specific days of the season you’ll explain why we receive a lesser tick weight into the men as compared to lady inside our research.
