Phenotypic Characterization of Crossed Goats F1- (Desert Goat and Damascus)

This study was conducted in North Kordofan state, Western Sudan, during the period Feb 2016- March 2020 to study the Phenotypic Characterization of crossed goats (F1-Desert goat and Damascus).44 female Desert goats of average age of 3-4 years and average body weights33.18±0.84 kg, were purchased from the local markets. Two mature sexual Damascus bucks were used in the experiment in addition to two castrated local young ones (teasers) all animals were identified using ear tags, tested for brucellosis and treated against external and internal parasites. During gestation period goats were closely observed up to the time of kidding. Data concerning with crossed kids (phenotypic characers, body measurements, performance up to maturity) were recorded. Data were analyzed using Statistical Package for Social Sciences, software package (SPSS, V23, 2017)). The results indicated that Male kids were significantly (P<0.01) heavier than females (2.74±0.48 visas 2.04±0.14kg). 27% mortality rate was recorded in kids. 71% of crossed goats (first generation) had light blue eye color. The flock had different coat colors (light brown, reddish brown and dark brown). The udder was somewhat small and attached to the abdomen the average body weight at kidding was 26.28 ± 1.56 and 22.03± 1.27 kg for single and twins, respectively

Productive Performance of F1- (Damascus Goat × Desert) under Traditional Management in North Kordofan

This study carried out in North Kordofan state, Western Sudan (latitudes 12:15-16:32 N and longitudes 27-32 E), during the period Feb 2018 - Aug 2021 to assessment the productive and reproductive performance of crossed F1 (Desert× Damascus) under the traditional management systems, to evaluate adaptation of crossed to environmental conditions of study area, to study milk production of the crossed goats. 44 females crossed goat F1 (Damascus×Desert goat) were selected at weaning age. Two mature Damascus bucks were used in the experiment all animals were identified using ear tags and treated against external and internal parasites. All animals will set free during the day and kept in closed pen during the night. The behavior of the animals and the adaptation on the environment was observed and recorded in addition to any problems like disease; Data were analyzed using the Statistical Package for Social Sciences, software package (SPSS, V23, 2017). In this study, the Damascus Bucks were severely affected under the conditions of nature grazing and suffered from parasites and high temperature, Bucks have died as a result of tick fever according to Anatomical symptoms, The parameters of dams varied according to litter size, Females were born as a single reached puberty at (278.2±7 days) with body weight of 20.01 kg while the twins females was puberty age (291.6±9 days), and weight was 16.91kg , The average lactation period was 120 days with average total milk production of 40.46± 1.74 kg, this study conclude that the crossed Females are late in sexual maturity, So The genetic cross as a way to improve the herd without taking into account environmental conditions does not lead to the desired results.&nbsp

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
