RESUMEN
Nodding Syndrome (NS) was recently described in children in Northern Uganda. The affected children were in the age group 5 – 15 years. They were stunted, malnourished, dehydrated, mentally retarded and get recurrent seizures. The objective of this study was to describe the cluster distribution of NS cases in Northern Uganda. We conducted a cross-sectional study using available data on the burden of NS in Northern Uganda and used GPS to map the locations of the most affected areas. The results obtained indicate that Nodding Syndrome in Northern Uganda occurs in clusters in the following locations Odek, Atiak, Angagura, Awere, Laguti, Labongo-Amida, Atanga, Pajimo, Palabek Kal and Palabek Gem sub counties and mainly along Aswa and Pager rivers and their tributaries. Nodding Syndrome in Northern Uganda occurs in clusters predominantly along two rivers; perhaps it is an indication for environmental, dietary and common epidemiological exposures for the syndrome.
RESUMEN
Recent studies have suggested the utilization of maggots as a feed supplement for enhanced broiler performance. Maggots, which are a major dietary source of protein, appear during the biodegradation of chicken droppings using house flies. The objective of the present study was to investigate the effect of maggot supplementation on the meat quality and growth performance of broiler chickens. A total of 600 one-dayold male commercial broiler chicks (Ross) were randomly assigned into 5 treatment groups consisting of 40 replicates of 3 birds. The birds were fed either a basal diet or the basal diet supplemented with 5.0, 10.0, 15.0 and 20.0% maggots. Overall, broiler chicken performance was influenced by the optimal amino acid profile; high protein (63.99%) and essential amino acid content (29.46%), or high protein digestibility (98.50%) of the maggots. Maggot supplementation caused linear increases in live weight gain but not the feed conversion ratio. The diets of 10 and 15% maggots was the most efficient in terms of average weight gain for the 4-5 week old broiler chickens(p<0.05). It also significantly increased dressing percentage, breast muscle, and thigh muscle (p<0.05). No differences were observed for liver, abdominal fat, or meat color, and the crude protein contents of breast muscle were constant. However, in the maggot-fed broilers, breast muscle lysine and tryptophan levels increased significantly as compared to the birds fed the basal diet (p<0.05). These results indicate that feeding diets containing 10 to 15% maggots in chicken dropping after biodegradation can improve the carcass quality and growth performance of broiler chickens.
