Compares the performance of Landim and Blackhead Persian sheeLarger litter size of Landim sheep compared to Blackhead Persian and BHP X Landim, and similar parturition intervals in each genotype resulted in greater annual output of young in the Landim than in BHP or in BHP X Landim. Weights of al...

A feeding system, draught cows, disease/work interactions and animal power introduction in a farming system are reviewed. A new feeding system for draught animals is described which enables feed requirements and the effects of work on liveweight and milk yield to be calculated. Recent data on the...

Red Maasai and Dorper sheep were evaluated for their resistance to gastro-intestinal (GI) nematode parasites (predominantly Haemonchus contortus), productivity and productive efficiency (assessed on a metabolizable energy basis) in experiments undertaken at the Kenyan coast (sub-humid environment...

An estimate of the economic loss due to ovine fasciolosis in the Ethiopian highlands was made based on available data on mortality, weight loss, reduced reproductive efficiency and liver condemnation at slaughhter. The economic effects of fasciolosis were identified and models for estimating the ...

Two important components that determine sheep production efficiency are reproduction and live body weight. An understanding of environmental factors affecting these traits is needed to implement optimal breeding and selection programs in Benin (West Africa). In this study, age at first lambing, l...

Relative importance of harvest index (I) and total biomass yield (B) to economic yield (Y) was assessed in several food crops at different levels of environmental productivity. Importance of B is generally higher in low than high yielding environments, while that of I is higher in high than low y...

We examine the geographic dimensions of food consumption in Ecuador, which has one of the highest rates of chronic infant undernutrition in Latin America. We use statistical and spatial analyses to examine the distribution of food consumption and food poverty and to test and generate hypotheses o...

Root turnover may contribute a significant proportion of recycled nutrients in agroforestry systems and competition between trees and crops for nutrients and water may depend on temporal fine root regrowth patterns. Fine root biomass (? 2 mm) and fine root productivity were measured during one ye...

This manual gathers information on the ecology and silviculture of Anthocephalus cadamba Miq., with a focus on Indonesia. It also includes growth and yield data from published sources, collected from smallholders’ farms in the research sites in South Kalimantan province, and collected previously ...
