(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
Dialogue
There is certainly a scant amount of data on literature into tick weight in cows to possess warm regions from the Americas. Very studies with this material was indeed done in subtropical nations eg Southern area Africa [8, 15], places having significant higher temperature particularly Egypt and you may Pakistan , and several tropical nations like Tanzania and you may Nigeria . Tick load can be said playing with turned study, that renders effect analysis having genuine tick weight tough to understand. This study reveals the actual tick weight and its own experience of temperature fret indicator in the five Bos taurus types located in about three other geographic areas of Colombia (new Caribbean, Andean and you will Orinoquia places). Tick load throughout these Colombian cows types was below you to included in a research using steers grazing from the Meta department (Orinoquia part). Concurrently, the common tick weight based in the five Colombian breeds into the the try (17.4 ± 24.6) is lower than you to definitely found in almost every other tropical regions instance brand new B. indicus Meru crossbred during the Tanzania (37.5 ± eleven.8) and lots of B. indicus cows communities (Light Fulani and Bunaji breeds in addition to their crossbreds) during the Nigeria (twenty-two ± 1.4) . Various cattle breeds, lawn types, grazing administration, herding program, climate and you will ecological areas of ticks you’ll give an explanation for large tick burden included in these almost every other education.
Tick delivery to your cows government
The latest tick load for the rump and you may tail from SM (seven.2 ± 12.2), ROMO (5.8 ± 10.2) and you may CCC (9.cuatro ± fifteen.1) cows was greater than brand new tick burden located on the butt ft, stomach and you may flanks (step one.0 ± 2.cuatro, cuatro.six ± 6.nine and you will 7.2 ± 11.step kissbrides.com baДџlantД±ya bir gГ¶z atД±n 1, respectively). Such show agree with those gotten because of the when you look at the Nguni cows. These authors discovered that the fresh new tick load on end and you can perineum was more than this new tick load towards the tummy in the seasons. A minimal tick load inside the BON, ROMO and you can CCC cattle is seen towards direct and neck followed by the trunk and you can loin. Similarly, Asmaa mais aussi al. discovered that a reduced amount of clicks were seen around the sight, shoulder and you may tits. Clicks favor hidden and you will warm anatomical areas to your animal body . And that, the right ecosystem to possess tick success are in tail and you can perineum, perhaps outlining this new lot from presses noticed during these body areas. On top of that, the rear base, udder, belly, fore and you will rear flank are more met with lawn, and this with ease achieved from the clicks. This really is the reason why we seen a leading ratio of the complete tick burden throughout these human body zones.
Different varieties of lawn and paddocks where these pets offer you can expect to cause variations in tick burden by anatomical zones. This will be substantiated because of the similar percentage of tick weight because of the anatomical zones seen toward ROMO and you may CCC breeds, which were found at a comparable experimental station and you can was indeed given with similar version of yard. Having said that, new tick load of the anatomical area is really more for the BON and SM types, and is to some extent informed me because of the an alternative ecosystem.
Sex, ages and you can real time weight
The greater tick load seen in lady will follow the outcome away from Rehman mais aussi al. for the Pakistani cattle, where female had a substantially higher tick weight than males. In addition, there is certainly a higher prevalence regarding tick infestation in females (58.7%) than in men (41.5%) from inside the Egyptian cattle . On the other hand, zero significant differences have been discover into the infestation incidence regarding Roentgen. microplus anywhere between gents and ladies during the Indian cattle and you can Mexican cows . On fresh station where in fact the cattle in regards to our analysis was basically remaining, bulls received preferential management simply because they had sleep periods until the start of the next reproduction 12 months, and you can was allocated in the paddocks having a lower life expectancy stocking price. In contrast, cattle was indeed always leftover in the large equipping costs. That these conditions received by bulls while in the some months of your 12 months you will define why we located a lower tick weight in the males compared to the females in our study.
