Conference Paper 1987

Autor: Little, D.A. Anderson, F.M. Durkin, J.W.

Reports an experiment conducted by ILCA's Nutrition programme to supplement poor quality grass or crop residues that form the basis of many ruminant diets in Africa. Emphasizes the efficient utilization of readily available resources for optimal animal production, in which the influence of noug c...

Conference Paper 1981

Autor: Watson, R.M. Tippet, C.I.

Describes methods of assessing spotting or sighting bias in low-level aerial observations, with emphasis on an approach based on a static model sampling strip; includes data on the relative advantages of counting through perspex or open windows, and the efficiency of pilot/observers in comparison...

Autor: Rege, J.E.O.

The maximum likelihood parameters estimated in logistic analysis are in terms of a transformation of the original response variable and, although inferences are easily made about the sources of variation in the linearized model using standard procedures applied in regression analysis, the varianc...

Conference Paper 1991

Autor: Rege, J.E.O.

The note is divided into five parts, viz, sampling methods, multicollinearity or intercorrelation, autocorrelation, and estimable and testable functions. The first part discusses sampling procedures, sample size determination, random sampling, sampling by deliberate stratification, blocking and i...

Conference Paper 1983

Autor: Grandin, B.E.

Discusses the importance of wealth differences among producers in traditional pastoral production systems, describing a rapid method, dependent on informants, for determining the wealth rank of producers within a given community in order to stratify a population of producers before sampling.
