Abstract: The morpho-biometric characterization of local chicken "Kolonto" ecotype was undertaken in the department of Gaya. The objective of this study is to promote the breeding of the "Kolonto" ecotype in Niger. A sample of 111 hens and 35 roosters was photographed, described and measured individually. This sample was collected in 15 localities distributed in the 6 communes that count the department of Gaya. The results of this study show that there is a great diversity of plumage in the local chicken "Kolonto" ecotype. The predominant plumage is the mille fleur (16%), the white and the mottled (14%), the partridge (13%), the red (12%) and the golden cuckoo (9%). The average weight of the chicken "Kolonto" ecotype is 1346,5g against 1641,2g and 1253,5g respectively for the males and the females because of the sexual dimorphism highlighted by means of ANOVA carried out on the basis of the various quantitative parameters. The high variability of the local chicken "Kolonto" ecotype demonstrated by this study is an opportunity for a poultry breeding program.

Abstract: The pastoral rangelands of Ethiopia are located around the peripheral or the outer edge of the country, almost surrounding the central highland mass. Livestock in Ethiopia is dependent primarily on native grasslands and crop residues. Forage production has been regarded as one of the suitable strategies for increasing feed availability for enhanced livestock production among pastoralist communities in the rangeland of Yabello and currently, forage degradation has been pointed out as the most limiting factor for livestock production in the Yabello rangeland area. There are factors determining adoption of these practices and it vary with different socio-demographical issues within the pastoral household. This study was therefore conducted to assess the socio-economic and demographic factors influencing households’ participation in forage production in Yabello rangeland of Southern Ethiopia. Data was collected from 210 households and 6 extension workers in total from 216 interviewers through interviews using semi-structured questionnaire. Results indicate that gender of household head, education, social/development group membership and access to extension services were the most important factors influencing households’ participation in forage production. There is need for technical support to the pastoralist households towards starting and/or joining existing social groups, through which extension and training services aimed at enhancing forage production in the Yabello range land can be offered.

Abstract: Recently, because of 81Kr’s advantages of steady chemical property, long half-life and no extra source in the movement of groundwater, it is becoming an effective method to date old groundwater (age from 105-106 year). This paper summarizes the principles of 81Kr in groundwater dating and extraction method, presents the application of 81Kr in groundwater dating and discusses the problems of recent related researches, makes prospects of studies of radionuclide in hydrogeology chemistry, and provide scientific support for the measurement of 81Kr and the researches of old groundwater dating.
