Further physiopathological features of experimental Homeria glauca (Wood & Evans) N.E.Br. poisoning in Merino sheep.

چکیده
Three Merino sheep were given 3 g/kg of dried, finely-milled Homeria glauca (Natal yellow tulp) plant material intraruminally. Plasma glucose, cortisol, catecholamines and lactate were measured hourly and also at the moment of death. Rising plasma glucose was shown to be associated with rising plasma cortisol and catecholamines, and the metabolic component of tulp-associated acidosis was shown to be the result of lactate accumulation.

A genome-wide scan to detect signatures of recent selection in Australian Merino sheep
Domestication and selection are processes that conserve the pattern of genetic diversities between and within populations. Identification of genomic regions that are targets of selection for phenotypic traits is one of the main aims of research in animal genetics. An approach for identifying divergently selected regions of the genome is to compare FST values among loci to estimate the genetic v...

Two anaesthetized sheep were intoxicated with epoxyscillirosidin, the main cardio-active bufadienolide, extracted from Homeria pallida (Natal yellow tulp). The epoxyscillirosidin was injected intravenously as a bolus of 50 micrograms/kg, followed 30 min later by a continuous infusion in a normal saline drip (0.9% NaCl) at 25 micrograms/kg/h. In addition, another two conscious sheep were poisone...

متن کاملAn evaluation of some oxidative and enzymatic biomarkers in different stages of naturally occurring copper poisoning in sheep
BACKGROUND: The early stage of Copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. OBJECTIVES: To assess biomarkers in predicting early Copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally Copper poisoning occurrence in an industrial region. METHODS: Animals were divided into four experimen...
متن کاملFuture options to reduce reliance on surgical mulesing
During the early days of the development of the Australian Merino sheep, selection of sheep was based on subjective classing, which is still in practice. Showing of stud animals was also based on subjective classing. With this method some characteristics become fashionable, because of the perceived positive associations with production and fitness. However, some can only be described as fancy t...
