seroprevalence of foot and mouth disease virus infection in some wildlife and cattle in bauchi state, nigeria. | foot and mouth disease (fmd) is an important transboundary viral disease of both domestic and wild cloven-hoofed animals characterized by high morbidity with devastating consequence on the livestock worldwide. despite the endemic nature of fmd in nigeria, little is known about the epidemiology of the disease at the wildlife-livestock interface level. to address this gap, blood samples were collected between 2013 and 2015 from some wildlife and cattle, respectively, within and around the yankari ... | 2020 | 32257095 |
influence of cattle on browsing and grazing wildlife varies with rainfall and presence of megaherbivores. | in many savanna ecosystems worldwide, livestock share the landscape and its resources with wildlife. the nature of interactions between livestock and wildlife is a subject of considerable interest and speculation, yet little controlled experimental research has been carried out. since 1995, we have been manipulating the presence and absence of cattle and large mammalian herbivore wildlife in a kenyan savanna in order to better understand how different herbivore guilds influence habitat use by sp ... | 2017 | 27935669 |
influence of ageing on the physical qualities of the longissimus thoracis et lumborum and biceps femoris muscles from male and female free-ranging common eland (taurotragus oryx). | the physical quality changes (ph, purge loss, cooking loss, drip loss, warner-bratzler shear force and cie lab colour) of vacuum-packaged longissimus thoracis et lumborum (ltl) and biceps femoris (bf) muscles were determined for male (n = 6) and female (n = 6) eland during a 35-day post-mortem ageing period at 4 °c. the bf and ltl muscles reached maximum tenderness (57 to 67 n) at day 17 and 21, respectively, but could still be considered tough after ageing. purge losses increased throughout age ... | 2020 | 31470198 |
effect of species-specific differences in chromosome morphology on chromatin compaction and the frequency and distribution of rad51 and mlh1 foci in two bovid species: cattle (bos taurus) and the common eland (taurotragus oryx). | meiotic recombination between homologous chromosomes is crucial for their correct segregation into gametes and for generating diversity. we compared the frequency and distribution of mlh1 foci and rad51 foci, synaptonemal complex (sc) length and dna loop size in two related bovidae species that share chromosome arm homology but show an extreme difference in their diploid chromosome number: cattle (bos taurus, 2n = 60) and the common eland (taurotragus oryx, 2nmale = 31). compared to cattle, sign ... | 2016 | 26194101 |
minerals in the blood, hair, and faeces of the critically endangered western derby eland under human care in two wildlife reserves in senegal. | the widely used means of investigating animal mineral profiles are blood serum or plasma and internal organ tissues. the acquisition of these types of samples can be invasive and requires much effort. these factors become key obstacles in the case of rare and elusive species such as the western derby eland (taurotragus derbianus derbianus, wde), which is a critically endangered antelope with a current distribution limited to the niokolo koba national park, and two wildlife reserves in senegal. o ... | 2020 | 31338803 |
comparison of meat quality between eland (taurotragus oryx) and cattle (bos taurus) raised under similar conditions. | physical, chemical and sensory characteristics of meat were compared between non-domestic eland (taurotragus oryx) bulls (n=6) and domestic fleckvieh (bos taurus) bulls (n=6) which were finished under controlled conditions of feeding and management. musculus longissimus lumborum from eland were darker and less yellow in colour, with a higher ph24 and lower contents of intramuscular fat and total collagen, compared to cattle. contents (mg/100 g muscle tissue) and proportions (g/100 g of fa determ ... | 2014 | 23954274 |
larger antelopes are sensitive to heat stress throughout all seasons but smaller antelopes only during summer in an african semi-arid environment. | heat stress can limit the activity time budget of ungulates due to hyperthermia, which is relevant for african antelopes in ecosystems where temperature routinely increases above 40 °c. body size influences this thermal sensitivity as large bodied ungulates have a lower surface area to volume ratio than smaller ungulates, and therefore a reduced heat dissipation capacity. we tested whether the activity pattern during the day of three antelope species of different body size-eland, blue wildebeest ... | 2014 | 23417331 |
meiotic behaviour of evolutionary sex-autosome translocations in bovidae. | the recurrent occurrence of sex-autosome translocations during mammalian evolution suggests common mechanisms enabling a precise control of meiotic synapsis, recombination and inactivation of sex chromosomes. we used immunofluorescence and fish to study the meiotic behaviour of sex chromosomes in six species of bovidae with evolutionary sex-autosome translocations (tragelaphus strepsiceros, taurotragus oryx, tragelaphus imberbis, tragelaphus spekii, gazella leptoceros and nanger dama ruficollis) ... | 2016 | 27136937 |
