(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 is a scant amount of research throughout the literature with the tick weight in cattle to possess tropical places regarding the Americas. Very training about point were carried out in subtropical regions instance Southern area Africa [8, 15], places with extreme highest temperature particularly Egypt and you may Pakistan , and lots of exotic countries including Tanzania and you may Nigeria . Tick weight is commonly reported having fun with turned data, that makes impact review getting genuine tick weight hard to interpret. This study shows the real tick load and its connection with temperatures worry indices for the five Bos taurus breeds located in around three other geographical aspects of Colombia (the latest Caribbean, Andean and you will Orinoquia regions). Tick burden during these Colombian cattle types is below that utilized in an experiment having fun with steers grazing on Meta agencies (Orinoquia part). At exactly the same time, the average tick load found in the four Colombian types inside the our try (17.cuatro ± 24.6) is lower than just one present in other tropical regions for example the fresh B. indicus Meru crossbred during the Tanzania (37.5 ± 11.8) and some B. indicus cattle communities (Light Fulani and Bunaji types and their crossbreds) in the Nigeria (twenty two ± 1.4) . The many cows types, turf species, grazing government, herding program, weather conditions and environmental aspects of presses might explain the high tick burden utilized in such most other education.
Tick shipping into the cows bodies
The brand new tick load towards rump and you will end out-of SM (seven.dos ± twelve.2), ROMO (5.8 ± 10.2) and you will CCC (9.4 ± fifteen.1) cows is actually more than the new tick burden on the butt feet, belly and you can flanks (1.0 ± dos.cuatro, 4.six ± 6.9 and you will 7.dos ± eleven.1, respectively). These efficiency trust men and women received by within the Nguni cows. Such writers learned that this new tick weight toward end and you will perineum was greater than brand new tick load into the stomach regarding 12 months. The lowest tick load within the BON, ROMO and you may CCC cows was seen into head and you may shoulder followed by the rear and you may loin. Similarly, Asmaa et al. unearthed that a decreased amount of ticks was basically observed in the eyes, shoulder and you can tits. Ticks prefer invisible and you will loving anatomical areas on the creature human anatomy . And this, the right environment to have tick success was underneath the tail and perineum, possibly describing the newest large number regarding clicks seen in these human anatomy areas. On the other hand, the trunk feet, udder, stomach, fore and you will bottom flank be much more met with grass, and that without difficulty achieved because of the clicks. This is certainly exactly why i observed a top ratio of your katolinen naimattomien naisten lГ¤hellГ¤ minua own full tick load during these muscles zones.
Different types of yard and you will paddocks where this type of pet offer you certainly will end up in differences in tick burden from the anatomical zones. This is certainly corroborated because of the comparable percentage of tick weight by the anatomical zones noticed towards the ROMO and CCC breeds, which were found at an equivalent fresh channel and you may was basically given with the same type of yard. Alternatively, brand new tick load by the anatomical area is quite additional for the BON and you will SM types, that’s simply said from the an alternative ecosystem.
Sex, decades and you may real time pounds
The higher tick load found in women will abide by the outcome regarding Rehman ainsi que al. inside Pakistani cattle, where ladies got a dramatically highest tick load than guys. While doing so, there was increased frequency off tick infestation in women (58.7%) than in men (41.5%) inside Egyptian cows . Additionally, no high distinctions was discovered towards the infestation prevalence out of R. microplus anywhere between gents and ladies from inside the Indian cows and you will Mexican cows . From the fresh programs the spot where the cows for the data were left, bulls gotten preferential management simply because they had resting symptoms before the start of the second reproduction season, and you will was indeed allocated into the paddocks having less equipping price. Alternatively, cattle was always left on highest equipping cost. These particular standards received because of the bulls while in the certain weeks of one’s 12 months you are going to define the reason we discover a reduced tick burden during the guys than the ladies inside our research.
