Abstract: The present study was conducted with the objective to characterize the husbandry practices and phenotypic characteristics of mature Bati, Borana and Short-eared Somali goats kept under traditional management systems so that the information generated can be used in designing breeding programs. The study was covered five districts in four administrative zones of Ethiopia representing Bati (in Oromia Zone) and Kalu (in South Wollo Zone) for Bati goats; Yabello (in Borana Zone) for Borana goats and Shinille and Erer (in Siti Zone) for Short-Eared Somali goats. A total of 345 households interview was made and phenotypic measurements were taken on 601(468 females and 133 males) heads of adult goats with 4 pair of permanent incisors (PPI). However, because of difficulty of finding adequate number of 4PPI sample males, measurements were taken from 2PPI and above males. In this study, in number, goats accounted for 72.01, 50.93 and 47.38% of other livestock species in Siti, around Bati and Borana, respectively. The least square mean (±SE) of goat flock size (44.02±3.33) per household in Siti was significantly (p<0.05) higher than those observed in Borana (23.08±1.94) and Bati area (8.99±0.59). The major challenges of goat rearing in the studied areas include feed and water shortage, disease incidence and recurrent drought with different order of prioritization. Plain brown (deep and light) (51.85%) coat color was the predominant coat color observed on Bati goats of both sexes. Meanwhile, plain white coat color was most frequently observed on Borana goats (71.54%) and only 36.27% in Short-eared Somali goats. Though most quantitative traits showed slightly higher average values in the Bati goats, differences with Borana goats were not significant (p>0.05),whereas Short-eared Somali goats remained significantly (p<0.05) lower for most of the body measurement characteristics. The canonical analysis done on phenotypic measurements also put Bati and Borana goats closer by discriminating Short-eared Somali goat populations. The similarities between Bati and Borena goats and significance divergence of Short-eared Somali goats in phenotypic measurements suggested that the need of further molecular characterization study to validate information from phenotypic characterization. Correlation coefficient was consistently highest between live weight and chest girth in both sexes across the goat populations. Hence, linear measurements could be valuable to estimate live body weight for those farm communities where sensitive weighing scales are not readily available.

Abstract: Background and aims: The genus Burkholderia is highly diverse and may mediate plant growth via several mechanisms. The current study evaluates the role of strains from four Burkholderia species in maize growth promotion. Methods: Twenty three strains of diazotrophic Burkholderia species were applied to two maize genotypes (SHS5050 and BRS4157) under greenhouse and field conditions. Strains were tested for growth promotion in greenhouse during 40 days. Strain 41 from B. silvatlantica was used under field conditions. Parameters evaluated: biomass accumulation, N and root measurements in pots and grain yield, N % and N in the grains under field conditions. Results: Eleven strains were evaluated under soil substrate. The inoculation of the hybrid SHS5050 showed root biomass improvement using three strains, namely M130, M209 and PPe7. The highest acetylene reduction activity was observed in strain 41 from B. silvatlantica. Strain 41 from B. silvatlantica improved plant dry mass on both genotypes. This strain produced 31 % more aerial tissue and 7 % more root dry mass in the BRS4157 variety than it did in the control. Both genotypes planted at Seropédica, RJ, produced 7 % more grains under field conditions and the variety produced 10.9 % more grains in comparison to the non-inoculated control. Conclusion: Strain 41 from B. silvatlantica showed beneficial plant-growth promotion of maize under greenhouse and field experiments specially in a low fertility soil. |
