Langues : Américain (ame) Catégories : Alcaloïdes Analyse de variance En statistique, l'analyse de la variance (terme souvent abrégé par le terme anglais ANOVA : ANalysis Of VAriance) est un ensemble de modèles statistiques utilisés pour vérifier si les moyennes des groupes proviennent d'une même population. Les groupes correspondent aux modalités d'une variable qualitative (p. ex. variable : traitement; modalités : programme d'entrainement sportif, suppléments alimentaires ; placebo) et les moyennes sont calculés à partir d'une variable continue (p. ex. gain musculaire). Ce test s'applique lorsque l'on mesure une ou plusieurs variables explicatives catégorielles (appelées alors facteurs de variabilité, leurs différentes modalités étant parfois appelées "niveaux") qui ont de l'influence sur la loi d'une variable continue à expliquer. On parle d'analyse à un facteur lorsque l'analyse porte sur un modèle décrit par un seul facteur de variabilité, d'analyse à deux facteurs ou d'analyse multifactorielle sinon.

However, the effects of disease, inadequate nutrition and management constrain the potential of this resource. Ectoparasites are one of the primary contributing factors in the tanneries for sheep and goat skin rejection. The aim of this study is to assess the impact of medicinal herbal plant extracts on ectoparasites (ticks) on small ruminants in Ethiopia. According to scientific and ethnomedical data gathered from respondents (farmers), the plant species P. dodecandra, E. globulus, C. macrostachyus, J. schimperiana, and C. aurea were used (by farmers) for the study. Phytochemical screening of extracts revealed the presence of flavonoids, alkaloids, phenols and saponins, tannins. Ticks from small ruminants (i.e goat and sheep) were collected and an in vitro adult tick immersion test was carried out using concentrations of 6.25, 12.5, 25, 50, and 100 mg/ml of all medicinal plant extracts. The temporal tick mortality was observed within 24-hours. In order to compare the results, distilled water and 12.5% amitraz was used as positive and negative controls, respectively. After 24 hours of exposure, P. dodecandra, J. schimperiana, and C. macrostachyus extracts had a moderate (60%) effect on tick mortality; however, C. aurea extract at 100 mg/ml and E. globulus extract at 50 mg/ml and 100 mg/ml had the highest mortality rate (80%). The study found that following in vitro treatment for the studied plants, the mean tick mortality increased considerably with increasing concentration and exposure duration. The existence of phytochemicals (active ingredients) in several plants, such as phenols, flavonoids, alkaloids, tannin, saponin, etc., may be the cause of their anti-ectoparasite effects. The study’s findings suggested that these plants might be crucial in reducing the need for chemical based medicines as well as managing the population of resistant ticks in an environmentally friendly manner.

Effects of some important ectoparasites on the grain quality of cattlehide leather / A. L. Everett in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXII (Année 1977)

In tests under controlled conditions, horn flies, and two species of mosquitoes caused no significant damage to leather grain ; four species of hard ticks caused severe damage in every case, with no apparent differences among the species. Damage from the lone star tick is illustrated at different healing stages. In tests of cattle exposed to severe infestations of parasites under natural conditions, the shortnosed cattle louse caused no significant grain damage inleather ; horse flies and deer flies caused slight but consistent, and possibly significant, damage ; and incidentally occuring demodectic mites caused moderate to severe damage to some of the hides. The detailed nature of the damage is illustrated. Investigation of the mite infestations provided useful information on the transmission of demodectic (follicular) mange, or demodicosis.
