Abstract Animal breeders have exploited many technological advances for increasing genetic gain in economically and functionally important traits. The implementation of such technologies routine breeding programs has permitted gains traditional milk, meat egg production traits as well as, more recently, low-heritability like health, fertility, even behavior. As global demand animal products inc...

In order to protect the interest of all stake holders of livestock farming in India, it is necessary to protect innovations in livestock sector through appropriate IP instruments along with conservation and sustainable use of native livestock breeds and associated traditional knowledge through sui generis system in the modern IPR regime. The unique attributes of indigenous livestock breeds coul...

Semi-nomadic pastoralism was replaced by sedentary pastoralism in Inner Mongolia during the 1960's in response to changes in land use policy and increasing human population. Large increases in numbers of livestock and pastoralist households (11- and 9-fold, respectively) during the past 60 yrs have variously degraded the majority of grasslands in Inner Mongolia (78 M ha) and jeopardize the live...

Chemotherapy remains the foremost available tool for the control of nematode parasites. However, the substantial use of anthelmintics, combined with a scarcity of new anthelmintic classes, has led to a gradual increase in the resistance of nematode parasites to these compounds. Multi-Drug Resistance (MDR) in economically important livestock nematodes, such as Haemonchus contortus enables the pa...

Thirty-four contact farmers were interviewed on general farm characteristics and production constraints. The farming activities were categorised as either livestock only (41%), or mixed crops and livestock (59%). The surveyed farmers kept mainly cattle (10...

We applied an innovation framework to sustainable livestock development research projects in Africa and Asia. The focus of these projects ranged from pastoral systems to poverty and ecosystems services mapping to market access by the poor to fodder and natural resource management to livestock parasite drug resistance. We found that these projects closed gaps between knowledge and action by comb...

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...
