(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’s a light level of study from the books into tick weight into the cattle for exotic countries regarding Americas. Very training on this material had been carried out in subtropical places such as for instance South Africa [8, 15], nations with high highest temperatures including Egypt and you may Pakistan , and many tropical countries such Guyanese kadД±nlar iГ§in tanД±Еџma siteleri as Tanzania and you will Nigeria . Tick weight often is said using switched study, that produces effects assessment having actual tick weight difficult to translate. This research shows the genuine tick burden as well as relationship with temperatures stress indices into the five Bos taurus types based in around three additional geographical areas of Colombia (brand new Caribbean, Andean and you will Orinoquia countries). Tick load within these Colombian cattle types try lower than you to used in a research having fun with steers grazing on the Meta company (Orinoquia area). Concurrently, the common tick load found in the four Colombian types within the our very own try out (17.4 ± 24.6) is gloomier than one present in most other tropical regions like the latest B. indicus Meru crossbred in Tanzania (37.5 ± 11.8) and several B. indicus cows communities (White Fulani and Bunaji breeds as well as their crossbreds) inside the Nigeria (twenty two ± 1.4) . Various cattle breeds, yard variety, grazing administration, herding system, climate conditions and you can environmental regions of clicks might explain the high tick weight included in such almost every other studies.
Tick shipments towards cattle bodies
The brand new tick burden into the rump and you will end regarding SM (7.2 ± several.2), ROMO (5.8 ± 10.2) and CCC (nine.cuatro ± 15.1) cows is more than the tick burden on the bottom legs, stomach and you can flanks (1.0 ± 2.cuatro, 4.6 ± 6.9 and you can 7.dos ± 11.step one, respectively). This type of show go along with those acquired of the inside the Nguni cows. These people learned that this new tick weight toward tail and you can perineum was higher than new tick load on the stomach regarding the seasons. The lowest tick burden within the BON, ROMO and you may CCC cattle are seen on the head and shoulder with the back and you will loin. Furthermore, Asmaa et al. learned that a low quantity of ticks was seen within vision, neck and you can breasts. Ticks like hidden and you can warm anatomical areas toward animal body . Hence, the right environment to own tick survival is actually under the end and you will perineum, perhaps discussing this new high number of ticks noticed within these human anatomy areas. At exactly the same time, the rear base, udder, belly, fore and you may rear flank become more met with grass, and therefore without difficulty reached because of the ticks. This will be the reason why we seen a top proportion of full tick weight in these body zones.
Different types of lawn and you can paddocks in which this type of pets offer you will produce differences in tick load of the anatomical zones. This is corroborated by equivalent portion of tick burden by anatomical areas observed to your ROMO and you can CCC types, that happen to be located at an identical fresh channel and you may was provided with similar type of yard. Having said that, the brand new tick weight by anatomical region is very more inside BON and you can SM breeds, and that is in part said because of the a unique environment.
Sex, decades and you will alive weight
The higher tick load present in people will abide by the outcomes away from Rehman mais aussi al. into the Pakistani cattle, where lady got a considerably highest tick weight than simply guys. Concurrently, you will find a high incidence out-of tick infestation in women (58.7%) compared to males (41.5%) into the Egyptian cows . On top of that, no extreme variations was indeed receive toward infestation frequency out-of Roentgen. microplus ranging from women and men from inside the Indian cows and you may Mexican cows . On experimental station where cattle for our analysis had been left, bulls acquired preferential administration because they got sleep symptoms before the start of next reproduction seasons, and you may was basically designated during the paddocks which have a lower life expectancy equipping rate. However, cattle was basically always remaining in the highest stocking costs. These particular conditions acquired because of the bulls throughout the some days of your own season you’ll explain why we discover a lowered tick weight when you look at the males compared to the women within data.
