Haematological changes in N'Dama and Gobra Zebu bulls during Trypanosoma congolense infection maintained under a controlled feeding regimen

Trypanosoma congolense. The cattle were offered a diet which provided levels of protein and energy above maintenance requirement and a pair feeding regimen was used in order to eliminate the confounding anorexic effects of trypanosomosis on the traits studied. Packed red cell volume (PCV), red blood cells (RBC) and haemoglobin (Hb) were monitored weekly. Mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and mean corpuscular volume (MCV) were derived by computation. Significant breed differences (

P<0.001) values for RBC and Hb. PCV levels were similar in both breeds pre-infection. Post-infection, there was a significant (
P<0.001) infection effect on the RBC, Hb and PCV in both breeds. The pathogenic effects were more severe in the Gobra-Zebu bulls where three out of ten bulls compared with only one out of eight infected N'Dama bulls attained the low PCV threshold, treated and withdrawn from the study along with their pair mates. Throughout the infection in N'Dama cattle and during the first 6 weeks of infection in the Gobra-Zebu bulls, the infection presented a normochromic normocytic anaemia. However, in the chronic phase, the Gobra-Zebu bulls became macrocytic. The infection reduced total dry matter intake in both breeds although this persisted longer in the Gobra-Zebus. However, their pair-fed controls showed no haematological changes indicating that the anorexia was not compounding the effects of the infection. The severity and type anaemia in N'Dama correlates with their innate ability to resist the effects of trypanosome infection compared to the Gobra-Zebu bulls.</description><identifier>ISSN: 0001-706X</identifier><identifier>EISSN: 1873-6254</identifier><identifier>DOI: 10.1016/S0001-706X(97)00123-X</identifier><identifier>PMID: 9638271</identifier><identifier>CODEN: ACTRAQ</identifier><language>eng</language><publisher>Amsterdam: Elsevier B.V</publisher><subject>Anaemia ; Anemia ; Animal Feed ; Animals ; Biological and medical sciences ; Cattle ; Erythrocyte Indices ; Hematocrit ; Hemoglobins - analysis ; Human protozoal diseases ; Infectious diseases ; Male ; Medical sciences ; N'Dama ; Pair-feeding ; Parasitic diseases ; Protozoal diseases ; Tropical medicine ; Trypanosoma congolense ; Trypanosomiasis ; Trypanosomiasis, African - veterinary ; Trypanosomiasis, Bovine - blood ; Trypanosomosis ; Trypanotolerance ; Zebu</subject><ispartof>Acta tropica, 1998-06, Vol.69 (3), p.181-192</ispartof><rights>1998 Elsevier Science B.V.</rights><rights>1998 INIST-CNRS</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c420t-4ca75f4b4867ff48b521eff040971fc18eb8cb3593907e8e84691b63dc83a7f63</citedby><cites>FETCH-LOGICAL-c420t-4ca75f4b4867ff48b521eff040971fc18eb8cb3593907e8e84691b63dc83a7f63</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S0001706X9700123X$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3536,27903,27904,65309</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=2260608$$DView record in Pascal Francis$$Hfree_for_read</backlink><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/9638271$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Akinbamijo, O.O</creatorcontrib><creatorcontrib>Bennison, J.J</creatorcontrib><creatorcontrib>Jaitner, J</creatorcontrib><creatorcontrib>Dempfle, L</creatorcontrib><title>Haematological changes in N'Dama and Gobra Zebu bulls during Trypanosoma congolense infection maintained under a controlled feeding regimen</title><title>Acta tropica</title><addtitle>Acta Trop</addtitle><description>Haematological changes were monitored in Gobra-Zebu and N'Dama bulls following infection with
