The International Livestock Research Institute (ILRI) works for better lives through livestock in developing countries.
Ayantunde, A.A. et al. 
To address the problem of restricted access to grazing by cattle in wet season in the Sahel, a grazing trial was conducted to study the effect of duration of grazing and grazing method on cattle nutrition and performance. Twenty-four intact steers weighing 259 kg (SD=62) were randomly allotted to four treatments to study the effect of the combination of grazing method (tethering and close herd ...

Fan, B. et al. 
Genetic variability of 18 microsatellites in five Chinese goat breeds was characterized and then individual-breed assignments were implemented on the basis of microsatellite multi-genotypes. Although the low Gst value of 5.7% occurred among these breeds, the accumulated non-parental exclusion probabilities of 99.99% and the correct assignment percentage of 82% demonstrated that microsatellites ...

Effect of variety and harvesting management on the concentration of tannins and alkaloids in tagasaste (Chamaecytisus palmensis)
Assefa, G. et al. 
The first part of this study evaluated contents of hydrolysable tannins (HT) and condensed tannins (CT) of 65 accessions of tagasaste. In the second part, the effects of harvesting stage and growing season on the contents of HT, CT and alkaloids in different plant parts of the widely grown tagasaste variety 'MOA' was studied in a randomized complete block design. Regrowths of tagasaste was har ...

Multilocus sequence typing (MLST) of Mycoplasma hyopneumoniae: a diverse pathogen with limited clonality
Mayor, D. et al. 
A multilocus sequence typing (MLST) scheme was established and evaluated for Mycoplasma hyopneumoniae, the etiologic agent of enzootic pneumonia in swine with the aim of defining strains. Putative target genes were selected by genome sequence comparisons. Out of 12 housekeeping genes chosen and experimentally validated, the 7 genes efp, metG, pgiB, recA, adk, rpoB, and tpiA were finally used t ...

El Niño-Southern Oscillation, rainfall, temperature and normalized difference vegetation index fluctuations in the Mara-Serengeti ecosystem
Ogutu, J. O. et al. 
Understanding long-term climatic variability is basic to wise management and conservation of biodiversity. We analysed temporal variations in the local rainfall, temperature, Normalized Difference Vegetation Index and the hemispheric El Niño-Southern Oscillation (ENSO), using the Southern Oscillation Index and how they co varied in the Mara-Serengeti ecosystem of Kenya and Tanzania. Local rain ...

Evaluation of the recognition of Theileria parva vaccine candidate antigens by cytotoxic T lymphocytes from Zebu cattle
Akoolo, L. et al. 
East Coast fever (ECF) is a highly fatal lymphoproliferative disease of cattle caused by Theileria parva, a tick-borne intracellular apicomplexan parasite. Parasite antigens that are targets of protective cytotoxic T lymphocyte (CTL) responses are required to formulate a sub-unit vaccine against ECF. A number of CTL target antigens have recently been identified and initial evaluation has shown ...

Using choice experiments to assess smallholder farmers' preferences for pig breeding traits in different production systems in North-West Vietnam. Analysis
Roessler, R. et al. 
Livestock form key components of the livelihood strategies of many of the world's poorest people. However, despite the potential to alleviate poverty and improve food security through livestock development interventions, the lack of smallholders' participation in the planning and design of breeding programs has often been a major cause of the failure of such programs. Particularly in developin ...

Muchiru, A.N. et al. 
A number of studies have begun to show the large impact that pastoralism has on African savanna ecosystems. Here we look at the impact of abandoned settlements on the distribution of the large ungulates of Amboseli, Kenya. Monthly dung counts show that all 9 species studied are attracted by settlements for up to a century after abandonment. Densities increased in the first two decades of veget ...

A novel SINE family occurs frequently in both genomic DNA and transcribed sequences in ixodid ticks of the arthropod sub-phylum Chelicerata
Sunter, J.A. et al. 
Reassociation kinetics and flow cytometry data indicate that ixodid tick genomes are large, relative to most arthropods, containing = 109 base pairs. The molecular basis for this is unknown. We have identified a novel small interspersed element with features of a tRNA-derived SINE, designated Ruka, in genomic sequences of Rhipicephalus appendiculatus and Boophilus (Rhipicephalus) microplus tic ...

A field trial of production and financial consequences of helminthosis control in sheep production in Ethiopia
Tibbo, M. et al. 
We used a partial-budget analysis to evaluate profitability of different management strategies of three genotypes of sheep in a 2 × 2 × 3 factorial experiment conducted at Debre Berhan research station in the central highlands of Ethiopia. This involved two anthelmintic-treatment levels (treated vs. non-treated), two supplementary nutrition levels (protein-energy supplementation yes/no) and th ...
