“…Wright’s F-statistics strictures showing the inbreeding coefficient in this study was 0.041, which was higher than 0.03 found in Cameroon [21], but was similar to values obtained in many Chinese IC [24, 27]. The F ST permits the approximation of migratory entities in a population per generation (Nm) based on loci.…”

“…The PIC values found in this study exceeded those (0.29-080) of Cameroon’s IC [21], and (0.31-0.49) of Chinese IC [21,22], but lower than those obtained by Tang for black-bone IC breeds (0.67) [24]. The mean frequency of alleles per marker found in this study (10.89) exceeded those recorded in previous reports in Cameroon (9.04) [21], in Ghana (7.8) [25], in Iran (5.4) [26], in China (3.8) [27], in Egypt (7.3) [28], in Pakistan (9.1) [29] and in Vietnam (6.41) [30]. The values obtained in this study were, however, lower than those from Brazilian (13.3) [31] and in the same range as from Ethiopian chicken ecotypes (10.6) [32].…”

AbstractRwanda has about 4.5 million of indigenous chicken (IC) that are very low in productivity. To initiate any genetic improvement programme, IC needs to be accurately characterized. The key purpose of this study was to ascertain the genetic diversity of IC in Rwanda using microsatellite markers. Blood samples of IC sampled from 5 agro-ecological zones were collected from which DNA was extracted, amplified by PCR and genotyped using 28 microsatellite markers. A total of 325 (313 indigenous and 12 exotic) chicken were genotyped and revealed a total number of 305 alleles varying between 2 and 22 with a mean of 10.89 per locus. 186 distinct alleles and 60 private alleles were also observed. The frequency of private alleles was highest in samples from the Eastern region, whereas those from the North West had the lowest. The influx of genes was lower in the Eastern agro-ecological zone than the North West. The mean observed heterozygosity was 0.6155, whereas the average expected heterozygosity was 0.688. The overall inbreeding coefficient among the population was 0.040. Divergence from the Hardy-Weinberg equilibrium was significant in 90% of loci in all the populations. The analysis of molecular variance revealed that about 92% of the total variation originated from variation within populations. Additionally, the study demonstrated that IC in Rwanda could be clustered into four gene groups. In conclusion, there was considerable genetic diversity in IC in Rwanda, which represents a crucial genetic resource that can be conserved or optimized through genetic improvement.

The objective of this work was to assess the level of stress sensitivity of three genotypes of chickens differing in body weight. A total of 62 birds of the 3 genotypes (21 local chicken, 20 commercial naked neck and 21 fully feathered hybrid chicken were reared in confinement together, under the same conditions. Body parameters and body temperature (BT) at 30 weeks of age was recorded for each genotype 3 days. All other body parameter traits were differed significantly among the genotypes. Commercial naked neck and fully feathered had better in almost all the traits. However, at day1, BT1 were 41.435 °C, 41.709 °C and 41.915 °C respectively for local chickens, naked necks and fully feathered hybrids under 37.1°C of ambient temperature and relative humidity of 46 %.. At day 2, the BT2 were 41.271 °C, 41.637 °C and 41.825 °C respectively for local chickens, the naked necks and the fully feathered hybrids, under 36 °C of ambient temperature and relative humidity of 40 %. At day 3, the BT3 were 41.369 °C, 41.585 °C and 41.784 °C respectively, under 35.2 °C of the ambient temperature and relative humidity of 53 %. These last results showed that the local chickens on susceptibility to humid tropical heat stress were smaller than in commercial hybrid chickens.
