“…Our findings are in agreement with the report ( Mbanasor et al , 2003) that the mean RBC, Hb and PCV values in natural T. vivax- infected trypanotolerant Muturu (WASH) cattle in Nigeria were well within accepted normal values for cattle. An earlier study involving trypanotolerant WASH cattle in Ghana also reported normal PCV value despite the presence of trypanosome parasites ( Adam et al , 2012).…”

Background: Animal trypanosomosis is a major cause of economic loss in livestock production in Africa. A suggested control measure is to use breeds with traits of trypanotolerance. The study examines the effect of natural Trypanosoma vivax challenge on haematological parameters in two trypanotolerant cattle [N’Dama and West African Shorthorn (WASH)] herds. Methods: Trypanosoma vivax-specific primers were used to diagnose T. vivax infection in an N’Dama herd at Cape Coast in southern Ghana and a WASH herd at Chegbani in northern Ghana from May to July 2011 in a cross-sectional study. Levels of haematological parameters comprising packed cell volume (PCV), haemoglobin (Hb) concentration and red blood cell (RBC) and total white blood cell (TWBC) counts; differential WBC counts (neutrophils, lymphocytes, eosinophils, monocytes and basophils); and RBC indices of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were determined in blood samples and then compared between infected and uninfected cattle. Results: We found that haematological indices for infected and uninfected animals in both breeds were within the normal range. However, the mean PCV values for T. vivax-infected WASH and N’Dama were lower in infected compared to uninfected animals. The difference was significant ( p< 0.05) in N’Dama but not in WASH. Conclusion: Despite the presence of infection by T. vivax, N’Dama and WASH cattle maintained their haematological parameters within acceptable normal ranges, which confirms their trypanotolerant trait. This highlights the need for low-input traditional African farmers in medium, high and severe tsetse challenge areas to be educated on the advantages of N’Dama and WASH breeds to increase their utilization in integrated tsetse and trypanosomosis control programmes.

“…The WBC values obtained were within the normal range for rabbits (2.71 − 12.23 × 10 9 /L), reported by [ 18 ]. Total leucocyte counts are involved in the immunity reaction and defence of the organism [ 19 , 20 ]. Susceptible rabbits to acute infections may have a decrease in WBC count [ 21 , 22 ].…”

A divergent selection experiment for environmental variance of litter size variance was carried out in rabbits over thirteen generations. The aim of this study was to evaluate the inflammatory response in the two lines of the experiment, in order to analyse the effect of selection on susceptibility to diseases after challenging to stressful situations, such as 24 h after the first delivery. A total of 78 females were used in this study, 39 from each line. The line selected for litter size heterogeneity (the high line) showed lower white blood leukocyte count (WBC; −0.87 × 103/µL), lower percentage of basophils (−0.11%), higher concentration of TNF-α (+13.8 pg/mL), and greater concentration of CRP (+38.1 µg/mL) than the line selected for litter size homogeneity (the low line). The high line had also higher concentrations of bilirubin, cholesterol, gamma-glutamyl transferase (GGT) and alkaline phosphatase (ALP) compared to the low line (difference between lines were +0.08 µmol/L, +0.14 µmol/L, +0.35 U/L and +2.4 U/L, respectively). The high line showed higher inflammatory response than the low line, in accordance with a larger susceptibility to infectious disorders. In conclusion, the line selected to increase litter size environmental variability seems to have poor capacity coping with environmental stressors. Therefore, selection for litter size environmental variability can be a useful way to improve animal welfare.

“…The blood consisting of blood cells and plasma fulfils the transport, regulatory, protective and homeostatic functions (Nasyrova et al, 2006). Blood parameters are indispensible in the diagnosis, treatment or prognosis of many diseases (Mbanasor et al, 2003). Normal blood parameters of pigs have been reported from many parts of the world including Nigeria.…”

“…The blood consisting of blood cells and plasma fulfils the transport, regulatory, protective and homeostatic functions (Nasyrova et al, 2006). Haematological profiles are important indicators of health and disease in animals and have become indispensible in the diagnosis, treatment or prognosis of many diseases (Mbanasor et al, 2003). Determination of the haematological profiles reflects the physiological responsiveness of the animals to its internal and external environment (Esonu et al, 2001).…”
