Evaluation of Morphometric Differences among Indigenous Chicken Populations in Bale Zone, Oromia Regional State, Ethiopia

The study was conducted in five selected districts in Bale zone South East, Ethiopia to evaluate the morphometric difference among indigenous chicken populations. Simple random sampling method was used to select 400 households who owned indigenous chicken population. From these households, a total of 840 adult (more than 6 months of age) indigenous chickens (225 males and 615 females) were used for morphometric traits measurements. Linear measurements were taken to the nearest of 0.5 cm and body weight was recorded at a precision scale of 100 g. Multivariate variance analysis was used to determine major traits that differentiate chicken population. Canonical discriminant multivariate statistical analysis was conducted for more powerful traits comparisons. Stepwise discriminant analysis was conducted to check the discriminating power of the traits. Pairwise Mahalanobis analysis was carried out to see the distance between indigenous chicken in the study districts. The study revealed that there were significant variations in morphometric traits across the study districts except shank circumference and wing span in hens and shank length, comb height, comb length, beak length and wattle length in cocks. There were significant variations in linear body measurements between sexes. Pairwise Mahalanobis distances between indigenous chicken between most of study districts were significant. Generally, there were morphological traits variations observed among the indigenous chicken populations across the study districts and between sexes, which suggest that there is an opportunity for genetic improvement through selection. Thus, farmers should get technical supports how to select best indigenous chicken for breeding purpose and formulation of breeding plan should be implemented to conserve indigenous chicken genetic resources for genetic improvement strategies

Recruiting the social contacts of patients with STI for HIV screening in Lilongwe, Malawi: process evaluation and assessment of acceptability

OBJECTIVES: To explore acceptability of recruiting social contacts for HIV and STI screening in Lilongwe, Malawi. METHODS: In this observational study, three groups of “seed” patients were enrolled: 45 HIV-infected STI patients, 45 HIV-uninfected STI patients, and 45 community controls, who were also tested for HIV as part of the study. Each seed was given five coupons and asked to recruit up to five social contacts to the STI clinic. Seeds were told the programme for contacts would include HIV testing, STI screening, and general health promotion. Seeds were asked to return after one month to report on the contact recruitment process. Seeds received $2 for each successfully recruited contact. RESULTS: Eighty-nine seeds (66%) returned for one-month follow-up with no difference between the three seed groups (p=0.9). Returning seeds reported distributing most of their coupons (mean=4.1) and discussing each feature of the programme with most contacts—HIV testing (90%), STI screening (87%), and health promotion (91%). Seeds reported discussing their own HIV status with most contacts (52%), with a lower proportion of HIV-infected seeds discussing their HIV status (22%) than HIV-uninfected seeds (81%) or community seeds (64%) (p<0.001). Contact recruitment did not vary with socioeconomic status. CONCLUSIONS: Most seeds distributed all coupons and reported describing all aspects of the programme to most contacts. STI patients are able to act as health promoters within their social networks and may be a critical link to increasing STI and HIV status awareness among high risk groups
