A bacterial disease of rice not described previously has been observed in Central and South America. Symptoms are characterized by spreading brown blotches on the leaves. Systemic invasion by the pathogen causes necrosis of the vascular system of the leaves, resulting in their partial or total br...

Purebred Menz, first cross (50%) Awassi x Menz, and second cross (75%) Awassi x Menz sheep were bred and reared under common environmental and management conditions. Reproductive data and mature body weights were recorded over a 6-year period between 1982 and 1987. Over all genotypes and years, t...

Slaughter data from 304 Menz and 153 Horro rams were analysed to determine between breeds differences in yields of carcass and edible non-carcass components, with the primary aim of creating awareness in the way animal evaluations for meat production may be modified to incorporate local cultures....

A large proportion of the maize planted in the tropics and highlands of Latin America is associated with beans and other crops. Agronomic research generally has focused on the improvement of varieties and hybrids, and the development of systems and technology for monoculture. The high production ...

Twenty-five year (1965-89) data on the Blended goats from Malya Research Centre totalling 4799 records were analysed for live weights and growth traits from birth to 72 weeks of age. The Blended goat developed in Malya, Tanzania, is a stabilised three-way cross of the Kamorai (55%), Boer (30%) an...

Investigates environmental sources of variation influencing growth traits of the Dorper and Dorper X Red Maasai sheep with special reference to the relative performance of various geneotypes. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages...

This study is evaluating the resistance of Red Maasai sheep to endoparasite infections relative to Dorper sheep and a range of Red Maasai x Dorper crosses. The results confirm previous reports that both Red Maasai ewes and lambs are more resistant to endoparasites (predominantly Haemonchus contor...
