Research paper thumbnail of Hatchability, Growth Performance, Feed Efficiency, and Survival of Normal Feathered Local, Sasso-rir and Their F1-cross Chickens Under on-station Management Condition in Southern Ethiopia

After 14-days of brooding, 150 chicks of each genotype were randomly selected and further replicated in to five pens in a deep litter grower house consisting of 30 chicks each in a completely randomized design, and evaluated for a period of 16-weeks. Hatchability of fertile eggs was highest for LL (80.0 %), intermediate for LSR (68.6%) and lowest for SRSR (55.9%) chickens. The body weight (BW) of chicks at 2-weeks of age was 80.0, 76.3 and 61.5 g/bird for SRSR, LSR, and LL, respectively, the latter being the lowest (p<0.05). The respective BW at 8-weeks of age was 732, 587 and 451 g while at 18-weeks it was 1877, 1379 and 1070 g/bird and different from each other (p<0.05). During 3- to 8-weeks and 9- to 18-weeks growth periods, the LL chickens were inferior (p< 0.05) in feed intake ...

The 180 participants were chosen by random sampling techniques for qualitative and quantitative research. Data were collected by individual survey using open data kit. The collected data were analyzed using General Linear Model (GLM) of SAS software version 9.1 and Duncan Multiple Range Test (DMART) was also used to locate treatment means that were significantly different. Result From the flock composition the Hen contributes the highest proportion (39.2%) followed by Chicks (31.2%). Mean sexual maturity of local Hen and Cock was 24.95 ± 0.269 and 23.56 ± 0.36 weeks, respectively. Mean egg production performance of local chick...

Poultry production is a tool for livelihood improvement and poverty alleviation in the developing countries. Indigenous chickens are numerous but lower in egg production performance than exotic chickens in Ethiopia. Objective. To compare egg yield, feed conversion ratio (FCR), mortality, and egg quality traits of Normal feathered local (LL), Sasso-RIR (SRSR) and their F1-cross (LSR) chickens under on-station conditions. Methodology. Data on egg production, feed intake and mortality were collected for 33 weeks whereas egg quality was assessed at 6, 9 and 12 months of age at poultry farm of Hawassa University. The experiment was laid out with Completely Randomized Design with four replications. Results. Next to SRSR chickens, LSR performed higher than LL chickens in terms of egg number per hen (96.8), egg weight (46.9 g/egg), daily feed intake (102 g/hen), body weight (1882 g/hen), albumen height (5.97 mm), albumen weight (27.2 g/egg) and albumen weight ratio (56.8). FCR w...

The Tajima's D plot for each gene region (upper plot for each gene) is the Tajima's D value within 50 kb window plotted for both populations. The smaller (negative) Tajima's D value in Sanga population shows that the gene region considered is under positive selection. The FST plot (lower plot for each gene) is the FST values within 50 kb windows separated by 5 kb steps. (DOCX 300 kb)

Moreover, the two populations might be descended from different ancestral origins and they have been established and developed under different management histories. Ecological variability and demographic structure of the community may have also contributed to this divergence. Horro chickens are genetically more homogenous than Jarso chickens (Figure 4). The optimal K was 2, however biologically meaningful pattern was observed at K = 4 following the marketsheds sampled. Table 2. Indicators of genetic diversity (mean (std)).
