(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

Discover a scant number of studies throughout the literature towards tick load within the cows to own warm countries in the Americas. Most knowledge on this subject question have been carried out in subtropical nations particularly South Africa [8, 15], places which have extreme higher temperatures such Egypt and Pakistan , and many tropical regions such as Tanzania and you may Nigeria . Tick weight is oftentimes reported having fun with transformed data, that makes effect assessment to own real tick load tough to understand. This study shows the true tick load as well as experience of temperature worry indices inside four Bos taurus types situated in three additional geographical regions of Colombia (new Caribbean, Andean and you can Orinoquia places). Tick load on these Colombian cattle breeds was below that utilized in a research using steers grazing from the Meta institution (Orinoquia area). At exactly the same time, the average tick burden found in the four Colombian types inside all of our try (17.4 ± 24.6) is gloomier than simply that seen in other warm regions eg the fresh new B. indicus Meru crossbred when you look at the Tanzania (37.5 ± eleven.8) and many B. indicus cows populations (White Fulani and you will Bunaji breeds as well as their crossbreds) for the Nigeria (twenty-two ± step 1.4) . The different cattle breeds, yard variety, grazing management, herding system, climate and you can ecological aspects of ticks you will explain the large tick weight https://kissbrides.com/fi/ghanalaiset-naiset/ included in these types of other degree.
Tick delivery on cattle regulators
The fresh new tick burden on the rump and you will tail away from SM (7.dos ± 12.2), ROMO (5.8 ± ten.2) and you may CCC (nine.4 ± 15.1) cows is actually higher than the brand new tick burden found on the buttocks legs, stomach and flanks (step one.0 ± 2.4, cuatro.six ± six.9 and you can seven.dos ± eleven.step 1, respectively). These show trust people gotten of the inside the Nguni cattle. This type of article authors found that the tick load into the tail and perineum try higher than the fresh new tick weight with the stomach throughout the season. A reduced tick burden inside the BON, ROMO and CCC cows is actually seen towards head and you can neck followed closely by the rear and you may loin. Also, Asmaa mais aussi al. learned that a low amount of ticks was basically observed within the attention, shoulder and you will chest. Clicks prefer undetectable and you may loving anatomical zones on animal human anatomy . And therefore, an appropriate environment to own tick endurance try underneath the end and you may perineum, possibly detailing this new high number out of clicks seen during these system zones. At the same time, the back foot, udder, stomach, fore and rear flank be a little more confronted by yard, and this easily hit of the presses. This is exactly exactly why i noticed a high ratio of your full tick load throughout these body zones.
Different kinds of yard and paddocks in which such pet feed could produce variations in tick weight by the anatomical areas. This is corroborated by the similar portion of tick load by anatomical zones observed towards ROMO and you will CCC breeds, that have been found at an equivalent experimental route and you can had been fed with the exact same style of lawn. Alternatively, the brand new tick burden by anatomical area is very other in the BON and SM types, which can be simply said of the another environment.
Sex, ages and you will real time pounds
The greater tick weight observed in people agrees with the results regarding Rehman et al. during the Pakistani cattle, in which ladies got a considerably large tick load than men. Likewise, there is certainly increased frequency away from tick infestation in women (58.7%) compared to men (41.5%) inside the Egyptian cows . In addition, no high distinctions had been discover to the infestation incidence off Roentgen. microplus between males and females inside the Indian cattle and you may Mexican cattle . In the fresh stations where cattle in regards to our study was basically leftover, bulls gotten preferential government simply because they had resting periods till the start of next breeding season, and you can were assigned inside the paddocks having a diminished stocking speed. On the other hand, cows was indeed constantly left in the highest stocking prices. Why these standards gotten of the bulls throughout the specific days of your 12 months you’ll identify the reason we located a reduced tick load for the men versus women within data.
