The continuous rising price of maize due to an increasing competition between humans and livestock requires palliative measures to sustain animal production. cassava-sweet potato meal combination can be used as a substitute for maize in feeding chicken. This study aimed at improving poultry productivity through the enhancement of the reproductive performances of Cameroon Kabir chickens fed pelleted diets of graded levels inclusion of cassava-sweet potato meal as an energy substitute for maize.315 Kabir chickens (270 hens and 45 rosters) of 23 weeks of age, were randomly allocated to five treatments T1, T2, T3, T4 and T5 with graded levels of cassava-sweet potato meal as energy substitute for maize, and eggs were collected for the evaluation of laying performances and characteristics. Fertility and hatchability were also evaluated across four successive batches of incubations. The eggs? weight was significantly (P<0.05) different between treatments at weeks 2, 4, 5 and 12, highly significant (P<0.01) at week 9, and very highly significant (P<0.001) at week 6, 7, 8 and 10. The highest number of eggs laid, egg weight and mass were recorded in chicken receiving 25% (T2) replacement of maize with cassava and sweet potato meal, followed by T4 (75%), T5 (100%), T3 (50%) while T1, receiving control diet without cassava and sweet potato meal performed less for all the parameters. Generally, the trend of the feed conversion ratio was decreasing with increasing the inclusion level of cassava and sweet potato meal. The egg index showed significant differences in weeks 6 and 12, while week 2 showed high significant difference between the treatments. T2 (25%) recorded the highest fertility, while animals receiving control ration without maize substitution recorded the highest hatchability. In general, incorporation of 25% of fifty-fifty percent weight to weight of cassava and sweet potato meal can be recommended for reproduction in chicken without affecting neither the hatchability nor the physical characteristics of the eggs, though hatchability will require better attention.

Genetic diversity is essential for any breeding program. However, breeders tend to concentrate on specific genotypes, which combine traits of interest and may be used as progenitors in several breeding programs. Common bean (Phaseolus vulgaris L.) breeding programs are not different in this sense. In this study, the genetic diversity of 21 common bean elite lines from the Bean Regional Trials conducted by the Embrapa Rice and Bean Research Center was evaluated using the Random Amplified Polymorphic DNA (RAPD) and pedigree analyses. Based on genetic dissimilarity, three groups were defined: group I - lines 1, 9 and 10, with low genetic distances among them (0.00 to 0.06), originated from 11 Mesoamerican parents; group II - 17 lines with genetic distances ranging from 0.03 to 0.33, originated from 50 parents (mostly Mesoamerican); and group III - line 21 (PR 93201472), which parents are the Andean cultivar 'Pompadour' and the cultivar 'Irai' (unknown origin). The genetic distances between line 21 and the lines of the other two groups varied from 0.68 to 0.93. Pedigree analyses demonstrated that cultivars 'Carioca', 'Cornell 49-242', 'Jamapa', 'Tlalnepantla 64', 'Tara' and 'Veranic 2', all of Mesoamerican origin, were the most widely used parents for developing lines present in group II. |
