(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 is certainly a light amount of study on the literature into the tick weight into the cows for warm regions regarding the Americas. Really training on this issue was indeed carried out in subtropical regions including Southern Africa [8, 15], nations with tall large temperatures such as Egypt and you may Pakistan , and many warm places particularly Tanzania and Nigeria . Tick burden often is stated playing with switched studies, which makes results investigations for actual tick weight hard to translate. This research shows the real tick burden and its particular connection with heat fret indices in five Bos taurus types situated in three additional geographic areas of Colombia (the brand new Caribbean, Andean and you will Orinoquia places) https://kissbrides.com/dutch-women/amsterdam/. Tick weight within these Colombian cattle breeds are lower than you to definitely utilized in a research using steers grazing on the Meta agencies (Orinoquia region). Likewise, the typical tick load found in the five Colombian types inside the our very own test (17.4 ± 24.6) is leaner than simply that noticed in other warm places eg the fresh new B. indicus Meru crossbred inside the Tanzania (37.5 ± 11.8) and some B. indicus cows communities (Light Fulani and Bunaji breeds as well as their crossbreds) for the Nigeria (twenty-two ± step 1.4) . Different cows breeds, grass types, grazing administration, herding system, climatic conditions and you may environmental aspects of ticks you are going to explain the large tick weight utilized in these types of other training.
Tick shipment into cattle government
Brand new tick load into the rump and you can end of SM (7.dos ± several.2), ROMO (5.8 ± 10.2) and you can CCC (9.cuatro ± fifteen.1) cows are more than the brand new tick weight found on the buttocks base, tummy and you may flanks (step 1.0 ± dos.4, cuatro.six ± 6.nine and eight.dos ± eleven.step 1, respectively). These types of show agree with those people received because of the in Nguni cows. This type of experts discovered that this new tick burden to the end and you may perineum are more than the brand new tick burden into belly throughout the season. A decreased tick load during the BON, ROMO and you may CCC cows is actually seen into the head and you can neck with the trunk and loin. Similarly, Asmaa ainsi que al. unearthed that the lowest quantity of presses was in fact noticed within sight, shoulder and breasts. Clicks favor hidden and you may enjoying anatomical zones with the creature muscles . Hence, a suitable environment to possess tick survival was under the tail and you can perineum, maybe describing brand new high number of presses noticed on these body areas. On top of that, the back base, udder, stomach, fore and you can buttocks flank become more confronted by yard, and this with ease achieved because of the ticks. It is exactly why we seen a high proportion of total tick burden throughout these human body zones.
Different kinds of yard and you will paddocks in which these pet feed you certainly will end in differences in tick burden of the anatomical areas. This can be substantiated from the comparable portion of tick load from the anatomical zones seen toward ROMO and you may CCC types, which were found at a comparable experimental route and was in fact provided with the exact same brand of grass. On the other hand, the new tick weight by the anatomical region is quite more in the BON and you will SM types, and that’s in part said from the an alternate ecosystem.
Sex, ages and live lbs
The better tick weight found in people will follow the outcomes off Rehman et al. for the Pakistani cattle, in which women had a somewhat higher tick load than just males. At the same time, discover a higher incidence from tick infestation in females (58.7%) compared to men (41.5%) within the Egyptian cattle . Additionally, zero high differences was in fact found towards the infestation prevalence out of R. microplus between women and men in the Indian cattle and you may North american country cows . Regarding fresh channels where in fact the cattle for our studies was in fact remaining, bulls gotten preferential management since they got resting periods through to the beginning of the second reproduction 12 months, and was assigned from inside the paddocks which have a lower life expectancy equipping rates. Conversely, cows was basically always left on higher equipping cost. Why these conditions obtained from the bulls throughout the certain days of the 12 months you’ll determine the reason we located a lower tick burden in men than the ladies within our studies.
