(10,1528) = 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
Conversation
You will find a light quantity of analysis regarding Dominikler kadД±n personel the literature toward tick weight within the cattle having tropical regions regarding Americas. Most knowledge on this material was indeed done in subtropical countries for example South Africa [8, 15], regions having extreme large temperature for example Egypt and Pakistan , and several tropical places such Tanzania and you may Nigeria . Tick load is normally advertised using turned analysis, which makes result comparison having actual tick burden tough to translate. This research reveals the real tick weight and its relationship with temperature fret indicator into the five Bos taurus types located in around three additional geographical aspects of Colombia (the fresh Caribbean, Andean and Orinoquia regions). Tick weight on these Colombian cows breeds are below that utilized in a test playing with steers grazing regarding Meta department (Orinoquia area). Additionally, the typical tick load based in the five Colombian types inside the all of our try (17.4 ± 24.6) is leaner than just one found in almost every other exotic regions such as brand new B. indicus Meru crossbred for the Tanzania (37.5 ± 11.8) and lots of B. indicus cattle populations (White Fulani and you can Bunaji types as well as their crossbreds) in Nigeria (22 ± 1.4) . The different cattle types, yard species, grazing administration, herding system, climate conditions and you will environment areas of presses you will explain the highest tick load included in such most other knowledge.
Tick delivery towards cows authorities
The brand new tick burden on rump and you can tail out-of SM (7.2 ± twelve.2), ROMO (5.8 ± 10.2) and CCC (9.cuatro ± 15.1) cattle is actually more than the latest tick burden located on the rear foot, tummy and flanks (step one.0 ± 2.cuatro, 4.six ± 6.nine and you may eight.2 ± 11.step one, respectively). These efficiency accept those individuals obtained because of the inside the Nguni cattle. These types of experts found that this new tick load toward tail and you will perineum was greater than the newest tick burden on belly regarding 12 months. A decreased tick weight inside the BON, ROMO and you will CCC cattle is seen into the head and you can neck followed by the back and you can loin. Furthermore, Asmaa mais aussi al. discovered that a low level of clicks was in fact seen inside the sight, shoulder and you will chest. Presses like invisible and warm anatomical areas towards the animal human body . And that, the ideal environment to possess tick survival are under the tail and perineum, maybe explaining this new large number out-of presses observed throughout these human body areas. Concurrently, the back ft, udder, stomach, fore and you may bottom flank be more confronted with lawn, which easily achieved because of the ticks. This really is the reason why we seen a leading ratio of your overall tick load in these body zones.
Different kinds of lawn and you will paddocks where such pet supply you are going to cause differences in tick burden of the anatomical areas. That is substantiated from the equivalent percentage of tick load by anatomical areas noticed to the ROMO and you will CCC breeds, which have been found at the same experimental station and was provided with similar form of lawn. In contrast, the brand new tick burden by anatomical zone is really additional in the BON and you may SM types, and that’s partly said from the a special ecosystem.
Sex, ages and you will alive pounds
The better tick weight noticed in female agrees with the outcome out-of Rehman mais aussi al. inside the Pakistani cows, in which females got a somewhat highest tick burden than simply men. In addition, there was a top incidence regarding tick infestation in females (58.7%) compared to males (41.5%) into the Egyptian cattle . Simultaneously, zero tall variations had been found for the infestation incidence of Roentgen. microplus ranging from men and women in the Indian cattle and Mexican cattle . In the fresh programs the spot where the cows for our research had been remaining, bulls gotten preferential administration because they got sleeping periods up until the beginning of the 2nd reproduction season, and you will was allocated into the paddocks that have a lower equipping speed. On the other hand, cattle was indeed always leftover within higher stocking pricing. These criteria gotten from the bulls through the specific days of season you are going to establish the reason we receive a lower tick burden in the guys compared to the female inside our research.
