Effect of Transport on Physical and Haematological Status of Cattle in Bangladesh

Haematological, Oxidative Stress and Trace Elements Variations Associated with Emaciation in Pre-Slaughter White Fulani Cows

“…In this study, signs of dehydration, mainly sunken eyes and tenting of the skin, were observed more in the emaciated cows. In addition, pre-slaughter animals frequently undergo prolonged duration (up to 24 to 72 hours) without feed and water even in pre-slaughter pens (Personal comm., ;Jarvis et al, 1996;Alam et al, 2010;Rakib et al, 2016). As animals examined in the present study were recently transported, our findings on the haematology agree closely with findings of Rakib et al (2016) who found elevated levels of PCV and Hb in recently transported cattle intended for slaughter, these values were pointers to dehydration.…”

Furthermore, from this study, RBC counts did not exceed the reference range, therefore it could be concluded that the above-reference -range PCVs seen in 17% of cows (with 53% of these, EC) was not due to polycythemia or even erythrocytosis of splenic contraction.…”

“…The variable relationship between emaciation and parameters indicative of anemia specifically the PCV, may be influenced by the presence of other homeostatic perturbations such as dehydration, which could present a spurious increase in PCV (above reference range of 46%) as observed in some animals sampled in this study. The feed and water restriction, and exposure to high ambient temperature, overcrowding and stress causing diarrheas and nasal discharge associated with transport of cattle over long distances is a key factor that could precipitate dehydration (Rakib et al, 2016). In this study, signs of dehydration, mainly sunken eyes and tenting of the skin, were observed more in the emaciated cows.…”

Assessment of transport stress on cattle travelling a long distance (≈648 km), from Jessore (Indian border) to Chittagong, Bangladesh

“…The level of TLC increased just after transportation (6.2 thousands/µl before to 7.3 thousands/µl after) and then decreased to reach 5.3 thousands/µl in this study, which corresponds to other studies elsewhere in Bangladesh 41 and neighbouring countries. 7 The pattern of TLC changes might be due to the stimulating effect of glucocorticoids on TLC during long-distance transportation.…”

Effect of Dietary Inclusion of Sodium Bicarbonate on Digestibility of Nutrients and Immune Response in Caged Layers During the Summer

“…Dietary inclusion of different levels of NaHCO 3 depicted a significant increase in antibody titer against Newcastle disease in layers when compared to those fed diet without its addition. Environmental stressors have been known to affect immunity and innate resistance of the host directly or indirectly (Rakib et al, 2016). Therefore, increase in antibody titer against Newcastle disease virus in birds fed diets containing different levels of NaHCO 3 may probably be due either to less heat stress upon these birds because of reduction in their body temperature or lower cortisol concentration as compared to those of control group, or both.…”
