(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

There is a scant level of data on the literature to the tick burden during the cattle having exotic places in the Americas. Very training about this procedure was in fact done in subtropical regions particularly Southern area Africa [8, 15], places which have significant high heat such as for example Egypt and you will Pakistan , and lots of warm regions like Tanzania and Nigeria . Tick load is sometimes stated using transformed research, that makes result assessment to have real tick load hard to interpret. This research suggests the real tick load and its own connection with temperatures fret indicator for the four Bos taurus types based in three more geographic areas of Colombia (the latest Caribbean, Andean and you can Orinoquia nations). Tick weight throughout these Colombian cattle types is lower than one found in a test having fun with steers grazing from the Meta company (Orinoquia area). At exactly the same time, an average tick load found in the five Colombian breeds inside the check out (17.4 ± 24.6) is leaner than just that seen in other warm countries eg the latest B. indicus Meru crossbred in the Tanzania (37.5 ± eleven.8) and several B. indicus cows populations (White Fulani and you can Bunaji types in addition to their crossbreds) into the Nigeria (22 ± step 1.4) . The various cows breeds, grass variety, grazing government, herding program, climate and you will environment aspects of clicks you are going to give an explanation for highest tick load used in these almost every other https://kissbrides.com/tr/makedonya-kadinlar/ studies.
Tick shipment into cows government
The tick burden on rump and you can tail away from SM (seven.2 ± several.2), ROMO (5.8 ± 10.2) and you may CCC (nine.4 ± fifteen.1) cattle is more than the newest tick load on the rear feet, tummy and you may flanks (step one.0 ± 2.4, cuatro.six ± 6.9 and you may seven.2 ± eleven.step 1, respectively). This type of abilities accept those people acquired by the within the Nguni cattle. Such writers learned that the brand new tick burden on tail and you will perineum try higher than brand new tick weight towards the tummy regarding 12 months. A decreased tick weight from inside the BON, ROMO and CCC cows is seen toward direct and you will shoulder followed closely by the trunk and you can loin. Furthermore, Asmaa mais aussi al. unearthed that a reduced level of clicks were seen inside the eyes, neck and you can bust. Ticks favor hidden and you will warm anatomical zones for the creature looks . Which, an appropriate ecosystem to have tick success was beneath the tail and you may perineum, possibly outlining the latest lot of presses noticed in these system zones. Simultaneously, the rear foot, udder, stomach, fore and you will buttocks flank be much more exposed to lawn, hence easily hit by ticks. That is why we seen a top proportion of one’s total tick load during these system areas.
Different types of turf and you will paddocks where these dogs feed you’ll cause differences in tick burden by the anatomical zones. This is corroborated of the comparable part of tick load by anatomical areas observed into ROMO and you will CCC breeds, which were found at a comparable fresh station and you will have been provided with the exact same particular lawn. In contrast, brand new tick weight by the anatomical area is extremely some other in the BON and you may SM types, which can be in part informed me from the a different environment.
Sex, many years and you will alive weight
The higher tick weight seen in lady will follow the results of Rehman mais aussi al. from inside the Pakistani cows, where ladies had a notably higher tick load than simply guys. At exactly the same time, you will find a top frequency regarding tick infestation in females (58.7%) than in guys (41.5%) from inside the Egyptian cows . Likewise, zero high variations were found to your infestation incidence out-of R. microplus between men and women in the Indian cattle and you can North american country cows . On the fresh station where the cattle for our investigation have been left, bulls obtained preferential administration because they had sleeping periods before beginning of the 2nd breeding seasons, and you may was indeed assigned within the paddocks with a lesser equipping rates. However, cows was basically usually left during the higher equipping cost. That these criteria gotten of the bulls during certain weeks of your season you are going to describe the reason we found a lowered tick burden when you look at the guys as compared to women within research.
