Livestock production systems, their responses to the demand for animal-source food, and the implications for animal health services
Autor: B D Perry, J T Dijkman
Publikováno v: Revue Scientifique et Technique de l'OIE. 40:383-394
This paper reviews the rapidly changing global demands for animal-source foods, examines the agri-food systems behind these changes, and discusses the potential responses required by public-sector Veterinary Services to meet these new demands.

The energy expenditure of cattle and buffaloes walking and working in different soil conditions
Autor: J. T. Dijkman, P. R. Lawrence
Publikováno v: The Journal of Agricultural Science. 128:95-103
At the Centre for Tropical Veterinary Medicine, Scotland, during the summer months of 1987, two adult water buffaloes, two Brahman cattle and two Brahman × Friesian steers walked round a circular track on concrete or through 300 mm deep mud. Average

A note on the influence of negative gradients on the energy expenditure of donkeys walking, carrying and pulling loads
Autor: J. T. Dijkman
Publikováno v: Animal Science. 54:153-156
The extra energy used for walking on the level and on negative gradients above that used when standing still (Ew) (J/m per kg live weight) was measured in two entire male donkeys (Equus asinus). Ewwas not affected by speed within the measured range (

Effect of density and weight of load on the energy cost of carrying loads by donkeys and ponies
Autor: R A, Pearson, J T, Dijkman, R C, Krecek, P, Wright
Publikováno v: Tropical animal health and production. 30(1)
Two experiments were designed to compare the energy used in carrying loads by donkeys and ponies. In the first experiment 3 donkeys and 3 ponies were compared on treadmills in the UK. Density of load (lead shot or straw) had no significant effect on

Using a decision support tool to screen for pro-poor policies: Application of Extrapolate to smallholder dairy systems in East Africa
Autor: P. K. Thornton, P. J. Thorne, C. Quiros, D. Sheikh, R. L. Kruska, T. P. Robinson, J. T. Dijkman, M. Herrero
Publikováno v: Proceedings of the British Society of Animal Science. 2005:28-28
Extrapolate (EX-ante Tool for RAnking POLicy AlTErnatives) is a decision support tool to assess the impact of policy measures on different target groups. It is designed to serve as a “filter” that, given the broad characteristics of the populatio
