Mortality of Djallonke Lambs in Senegal
Description
Field trial to assess the effect of ewes deworming (prevention of gastro-intestinal parasitism) on the mortality
of their offspring (age < 1 year). This data set is extracted from a large database on small ruminants production
and health in Senegal (Lancelot et al., 1998). Data were collected in a sample of herds in Kolda (Upper Casamance,
Senegal) during a multi-site survey (Faug?re et al., 1992). See also the references below for a presentation of the
follow-up survey (Faug?re and Faug?re, 1986) and a description of the farming systems (Faug?re et al., 1990).
Usage
data(dja)
Format
A data frame with 21 observations on the following 4 variables.
- group
a factor with 2 levels: CTRL and TREAT, indicating the treatment.
- village
a factor indicating the village of the herd.
- herd
a factor indicating the herd.
- n
a numeric vector: the number of animals exposed to mortality.
- trisk
a numeric vector: the exposition time to mortality (in year).
- m
a numeric vector: the number of deaths.
