This paper explores resource allocation decisions in Kenyan rangelands. We analyse choice decision of the producer to enter or not to enter livestock production, and the optimal herd size that is expected to yield maximum benefits to the herder. We apply the Heckman two-stage estimation procedure to correct for selectivity bias in the livestock production, optimal income and optimal herd size p...

In a recent survey by the United States Department of Agriculture (1961) it was estimated that the animal-protein shortage in the deficit countries, in terms of non-fat milk solids, was the equivalent of 1.8 million metric tons or roughly one-third of the U.S. annual milk production. The most critical shortages were noted to be in the Far East, followed by communist Asia, Africa and Latin Ameri...

BACKGROUND European studies suggest that living near high-density livestock production increases the risk of sequence type (ST) 398 methicillin-resistant Staphylococcus aureus (MRSA) colonization. To our knowledge, no studies have evaluated associations between livestock production and human infection by other strain types. OBJECTIVES We evaluated associations between MRSA molecular subgroups...

Livestock production plays an important role in the economies of Colombia and Costa Rica; livestock production creates direct and indirect jobs and accounts for 32% and 21% of the land used. From an environmental point of view, livestock production contributes to the biological connectivity and forest cover, but it is also a major emitter of greenhouse gases (GHGs). Within the context of the Un...

The problem of food security during the last few decades has acquired a global character. Population growth, reduction of farmland suitable for agriculture and ecological factors has led to a sharp increase in food demand. In such conditions, the role of countries which are able to increase the export of agricultural production in short-term periods is rising. Ukraine has great opportunities fo...

The Food and Agriculture Organization of the United Nations predicts that the projected massive global increase in demand for livestock products will continue for several decades. According to Delgado et al. (1999), it is appropriate to term the course of these events a " Livestock Revolution, " which, as opposed to the Green Revolution, is driven by demand. While more precise production techno...

Angiosperms diversification was primarily driven by pollinator agents, but non-pollinator agents also promoted floral evolution. Gentiana lutea shows pollinator driven flower color variation in NW Spain. We test whether insect herbivores and livestock, which frequently feed in G.lutea, play a role in G. lutea flower color variation, by answering the following questions: (i) Do insect herbivores...

Arid and semi arid areas of Balochistan are characterized by low and erratic rainfall and are prone to drought conditions which normally occur every three to four years. Th e prevailing drought is one of the most severe in its magnitude as annual rain (60-150 mm) has been well below average for a continuous period of four to fi ve years in most parts of highland Balochistan. Results from a long...

Small ruminants are important assets in several regions of the world. They account for more than half of the domesticated ruminants. Despite the growth in goat production in the world (more than 2% per ye.ar), research related to goat production is less than desired. One underused but potentially valuable approach for research on small ruminants is sim­ ulation modelling. Models of the componen...
