Sudanese live sheep and mutton exports competitiveness

The Revealed Competitiveness of U.S. Exports

The U.S. share of world merchandise exports has declined sharply over the last decade. Using data at the level of detailed industries, this paper analyzes the decline in U.S. share against the backdrop of alternative measures of the competitiveness of the U.S. economy. We document the following facts: (i) only a few industries contributed to the decline in any meaningful way, (ii) a large part ...

Estimates of genetic and environmental (co)variances for live weight and fleece traits in yearling South African Mutton Merino sheep

Yearling live weight and fleece trait data were obtained from between 2214 and 2270 yearling SA Mutton Merino progeny of the Elsenburg flock during a 20-year period from 1983 to 2002. Information of (co)variances for these traits in SA Mutton Merinos is exceedingly scarce in the literature. Estimates of (co)variance components and ratios were thus obtained from these data, using an Animal Model...

Survey of Theileria lestoquardi antibodies among Sudanese sheep.

The prevalence of Theileria lestoquardi antibodies in Sudanese sheep from nine geographical areas in Sudan was determined using indirect fluorescent antibody "IFA" test. Out of 315 samples examined, 51 (16.2%) were found positive and ranged between 23.4% in River Nile State and 10% in Kasala and Darfour Provinces with an overall prevalence of 16.2% indicating widespread distribution of the infe...

Sensory and objective mutton quality characteristics of SA Merino sheep selected for and against reproductive fitness

The effect of divergent selection for ewe multiple-rearing ability over a 15-year period on mutton quality was examined on the M. longissimus dorsi and M. semimembranosus of entire rams (R) and ewes (E) derived from two Merino lines. The selection of these two lines was based on maternal ranking values for multiple-rearing ability in a positive (P) and negative (N) line. In the negative line th...
