Clinical manifestations, laboratory investigations and electromyography findings were documented. This case was reported because of its rarity and to emphasize the effects of hypothyroidism on muscular tissues so as to avoid delay in diagnosis and mismanagement. The reporting of Hoffman's Syndrome is very rare from Africa, and probably this is the first case from Sudan.. INTRODUCTION The neuromuscular manifestations of hypothyroidism vary from delayed relaxation of deep tendon jerks to full blown myopathy. Different myopathies were associated with hypothyroidism and can be divided into five subtypes: Kocher-Debré-Semelaigne syndrome, Hoffmann's syndrome, atrophic form, myasthenic syndrome and polymyositis-like syndrome [1,2]. Hoffmann's syndrome is a very rare form of hypothyroid myopathy, first described by Hoffmann in 1897. This syndrome occurs in adult...

The average age at first calving (AFC), gestation period (GP), number services per conception (S/C), calving interval (CI), total milk yield (TMY), daily milk yield (DMY) and lactation length (LL) ranges were 24..00±2.42 kg, and 376.74±15.89 -349.0±86 days respectively.

The study aimed at investigating the genetic variations of body weight at various ages. Range of heritability estimates for body weight from birth to 6th month was 0.04-0.54. The estimates from dam component ranged 0.28-0.68 which was higher than that from sire component estimates. The genetic correlations for body weight at various ages were substantially high, ranged from 0.51-0.99 as sire, dam and dam nested in sire components. Phenotypic correlations of body weight at various ages ranged from 0.43-0.99 with differences being significant (P<0.01). Low to high environmental correlations (0.10-0.33) were encountered as dam component. However, the random effect of sire was found to be significantly (P<0.01) positively correlated.

Also introduced mathematical descriptive for differential equation and difference equation. Finally, during this study, researcher were able to drive general rule for differentiation of z-transformation and generalize some z-transform properties, such as linearity properties of z-transformation for í µí± functions. This work does not go into Engineering applications.

The chicken populations were genotyped using mtDNA D-loop as a molecular marker. PCR product of the mtDNA D-loop segment was 600 bp and 14 haplotypes were identified. The neighbor-joining phylogenetic tree indicated that the indigenous Sudanese chickens can be grouped into two clades, IV and IIIa only. Median joining networks analysis showed that haplotype LBB49 has the highest frequency. The hierarchal analysis of molecular variance (AMOVA) showed that genetic variation within the population was 88.6% and the differentiation among the population was 11.4%. When the populations was redefined into two geographical zones, rich and poor Savanna, the results were fractioned into three genetic variations: between individuals within population 95.5%, between populations within the group 0.75%, and genetic variation between groups 3.75%. The pair wise st showed high genetic difference between Betwil populations and the rest with st ranging from 0.1492 to 0.2447. We found that there is large number of gene exchanges within the Sudanese indigenous chicken (Nm = 4.622).
