Viljoen, Devon M.; Webb, E.C. (Edward Cottington); Myburgh, Jan G.; Truter, Johannes Christoff; Lang, Jeffrey W.; Myburgh, Albert (Elsevier, 2023-12)The current study assessed the ambient temperatures, and those selected, by captive adult Nile crocodiles on a commercial farm in South Africa. Non-invasive data capture techniques were developed to ensure the crocodiles ...

Booth, Kenneth Kurt; Webb, E.C. (Edward Cottington) (Hindawi Publishing Corporation, 2011)Eighteen mature, nonpregnant, and indigenous South African does were randomly divided into two groups to test if their vomeronasal organs exert an influence on LHplasma levels during a Whitten effect experimental trial. ...

Tshuma, Tsakula; Fosgate, Geoffrey Theodore; Webb, E.C. (Edward Cottington); Swanepoel, Corlia; Holm, D.E. (Dietmar Erik) (MDPI, 2023-01)This study investigated the effect of ambient temperature and humidity on milk urea nitrogen (MUN) concentration in Holstein cows. Meteorological data corresponding to the dates of milk sampling were collected over six ...

Webb, E.C. (Edward Cottington); Veldsman, Devon Marie; Myburgh, Jan G.; Swan, G.E. (South African Society for Animal Science, 2021-02)Intensive Nile crocodile (Crocodylus niloticus) farming operates with considerable variation in housing and stocking density. In this study, current commercial stocking densities for crocodilians were investigated using ...

Petzer, Inge-Marie; Etter, Eric Marcel Charles; Donkin, Edward Francis; Webb, E.C. (Edward Cottington); Karzis, Joanne (Elsevier, 2017-12)An innovative method was investigated to aid in the elimination of Staphylococcus aureus (S. aureus) intramammary infections (IMI) from dairy herds. A stochastic model explore the economic benefit of three-day or eight-day ...

Esposito, Giulia; Irons, Pete Charles; Webb, E.C. (Edward Cottington); Chapwanya, Aspinas (Elsevier, 2014-01)The biological cycles of milk production and reproduction determine dairying profitability thus making management decisions dynamic and time-dependent. Diseases also negatively impact on net earnings of a dairy enterprise. ...

Holm, Dietmar Erik; Webb, E.C. (Edward Cottington); Thompson, P.N. (Peter N.) (American Society of Animal Science, 2014-11)Although fetomaternal disproportion is the major cause of dystocia in heifers, pelvis area (PA) is not recommended as a culling tool due to its relatively low importance and genetic correlation with calf birth weight ...

Petzer, Inge-Marie; Karzis, Joanne; Donkin, Edward Francis; Webb, E.C. (Edward Cottington) (AOSIS OpenJournals, 2016-08-30)A dedicated udder health diagnostic programme was developed and used over a 15-year period in South Africa to analyse milk samples based on microbiological and cytological patterns within various groups and for individual ...

Vernooij, Johannes; De Munck, Florine; Van Nieuwenhuizen, Evelien; Webb, E.C. (Edward Cottington); Jonker, Herman; Vos, Peter; Holm, Dietmar Erik (Wiley, 2020-11)Pelvis size plays an important role to prevent dystocia in cattle caused by the foetomaternal disproportion in commonly primiparous females. The reproducibility and repeatability are two important aspects for the reliability ...

McCrindle, Cheryl M.E.; Maime, Masethe Jan; Botha, Ester A.; Webb, E.C. (Edward Cottington); Smuts, Mario P. (AOSIS Open Journals, 2019-10)Calving rate in communal cattle influences both food security and socio-economics in rural households. A previous study indicated that scrotal damage caused by ticks could affect the fertility of communal bulls and reduce ...

Petzer, Inge-Marie; Karzis, Joanne; Donkin, Edward Francis; Webb, E.C. (Edward Cottington); Etter, Eric Marcel Charles (AOSIS OpenJournals, 2017-03-24)The objective of the study was to establish an operational somatic cell count (SCC) threshold to predict the presence of intramammary infection (IMI) in composite milk samples and compare findings with those in quarter ...
-
Petzer, Inge-Marie; Karzis, Joanne; Donkin, Edward Francis; Webb, E.C. (Edward Cottington); Etter, Eric Marcel Charles (AOSIS OpenJournals, 2017-04-13)The objective of this study was to determine whether somatic cell count (SCC) was an effective test, with a sensitivity exceeding 85%, to determine species-specific bacterial infections. In addition, the relation between ...
