Although the biological advantages in terms of animal production andimproved soil fertility of the use of herbaceous legumes have been well demonstrated in Kenya and elsewhere, adoption by small-scale farmers has often been disappointing. This has led to increased research into the use of both indigenous and exotic fodder trees. In common with conventional pasture legumes, tree fodders contain high levels of crude protein and minerals and many show high levels of digestibility. They are readily accepted by livestock and presumably because of their deep-root systems, they continue to produce well into the dry season. Antinutritive factors can be a problem, however, and polyphenolics, toxic amino acids, cyanogenic glycosides and alkaloids are found in many tree species. There are abundant niches on small farms where fodder trees can be grown without affecting crop production. Althoughdetailed management recommendations are lacking, guidelines exist with regard to appropriate cutting heights and harvesting frequencies. In the Embu region, it has been estimated that three kg of fresh fodder of Calliandra calothyrsus has the same effect on milk production as one kg of commercial dairy meal. Up to about 500 trees (250 m of hedgerow) will produce enough fodder to supplement one dairy cow for a complete lactation. The tree fodder can either replace the concentrate without loss of yield, or it can complement it to produce more milk. It is being enthusiastically adopted by small-scale farmers, many of whom are starting to produce their own seed. Other tree species arenow being studied in order to avoid over-reliance on a single fodderspecies. [ABSTRACT FROM AUTHOR]

Setting: Nairobi, the capital of Kenya., Objective: To promote standardised tuberculosis (TB) care by private health providers and links with the public sector., Design and Methods: A description of the results of interventions aimed at engaging private health providers in TB care and control in Nairobi. Participating providers are supported to provide TB care that conforms to national guidelines. The standard surveillance tools are used for programme monitoring and evaluation., Results: By the end of 2006, 26 of 46 (57%) private hospitals and nursing homes were engaged. TB cases reported by private providers increased from 469 in 2002 to 1740 in 2006. The treatment success rate for smear-positive pulmonary TB treated by private providers ranged from 76% to 85% between 2002 and 2005. Of the 1740 TB patients notified by the private sector in 2006, 732 (42%) were tested for human immunodeficiency virus (HIV), of whom 372 (51%) were positive. Of the 372 HIV-positive TB patients, 227 (61%) were provided with cotrimoxazole preventive treatment (CPT) and 136 (37%) with antiretroviral treatment (ART)., Conclusion: Private providers can be engaged to provide TB-HIV care conforming to national norms. The challenges include providing diagnostics, CPT and ART and the capacity to train and supervise these providers.
