The main objective of this study was to identify and document plants traditionally used for treating livestock diseases and conditions in Lake Victoria basin of Kenya, Tanzania and Uganda. In Kenya, the study sites were located in Kendu Bay, Kano Plains, Suri and Yala wetlands; in Tanzania in the districts of Missungi, Magu, Sengerma, Geita, Ukerewe and Ilemela, while in Uganda in the district of Rakai. The study utilised employed participatory rural appraisal tools, mainly focus group discussions and key informant interviews. A wide range of plants with veterinary medicinal uses were identified and documented. The highest number of plants was enlisted in Kenya (81), followed by Tanzania (50) and lastly Uganda (24). Examples of plants mentioned were Xylopia aethiopica for treating East Coast Fever, Phragmites mauritianus for treating retained placenta, Hoslundia opposita for treating snake bites and Cassia occidentalis for treating internal parasites. Some plants were common in all the three countries, while others were only mentioned in particular countries. Other livestock diseases and conditions traditionally treated included diarrhoea, pneumonia, eye infections, heart water, babesiosis, mastitis, snake bites and wounds. The study points out the need for validating and integrating the use of traditional medicinal plants in community-based animal health care delivery systems in the East African region. |

We used the Livestock Analysis Model (LAM) to estimate the current and projected amount of methane, a greenhouse gas, produced by the cattle population in Uganda in the period from 2000 to 2030. The LAM is a data-intensive computer model developed by the United States Environment Protection Agency. The data required for the model were derived from official documents of the Government of Uganda. Secondary data on human and cattle population and production target of beef and milk were subjected to stepwise regression analysis and the outputs were used in the LAM. Primary data for the LAM were also generated through a national livestock survey. According to the LAM, the total methane emissions from cattle in Uganda in the year 2000 were estimated at 337,796 tons. This amount is projected to nearly triple by the year 2030 unless appropriate mitigation measures are put in place in the country. Among indigenous cattle breeds, the Zebu and Nganda had the highest methane emissions per unit of product, generating approximately 1 kilogram of methane per kilogram of milk produced, while the Ankole cattle emitted approximately 0.566 kg of methane per kilogram of milk produced. On the other hand, the improved breeds emitted only 0.123 kg of methane per kilogram of milk produced. The results of this study show that the cattle sector in Uganda has a potential for international investments for reduction of methane emissions in line with the Clean Development Mechanism under the Kyoto Protocol. |

Concentrations of polychlorinated biphenyls and organochlorine pesticides were determined in muscle and liver samples of Nile Perch (Lates nilotica) caught from the Ugandan part of Lake Victoria. Our overall objective was to assess human exposure risk to these chemicals through consumption of fish. Six organochlorine pesticide residues and 3 polychorinated biphenyl congeners were found in fillet samples in the following proportions: hexachlorobenzene (6.7%), dieldrin (3.3%), p,p`-DDE (83.3%), o,p`-DDD (6.7%), p,p`-DDD (3.3%), p,p`-DDT (20%), PCB-153 (13.3%), PCB-138 (13.3%) and PCB-180 (16.7%). The concentrations of these contaminants in muscle were generally low. The mean concentration of total DDT in muscle was 0.001 mg kg 1 fresh weight and the highest recorded level was 0.003 mg kg 1 fresh weight. DDE constituted on average 94% of total DDT in fillet. In liver samples, 9 organochlorine pesticide residues and 4 PCB congeners were found in the following proportions: Hexachlorobenzene (20%), -HCH (13.3%), -HCH (6.7%), lindane (10%), dieldrin (36.7%), p,p`-DDE (83.3%), o,p`-DDD (3.3%), p,p`-DDD (33.3%), p,p`-DDT (13.3%), PCB-52 (3.3%), PCB-101 (16.7%), PCB-153 (16.7%) and PCB-138 (13.3%). The mean total DDT was 0.003 mg kg 1 fresh weight, with the highest concentration of 0.01 mg kg 1 fresh weight. The mean residue levels of total DDT and dieldrin were 0.12 and 0.3% of the respective German maximum residue limits. The estimated average adult daily intakes of the total DDT residues through fillet consumption was only 0.0005% of FAO/WHO maximum acceptable daily intake. |
