    Get PDF
    Wool is a natural fibre with a unique amalgamation of properties that are exploited in garment industry. The wool industry, in particular the production of fine wool, has a notable role in world trade and the price of the wool is dependent on quality. Accordingly, wool characteristics have direct impact on wool prices set by processors and industry. These properties can particularly benefit the wearer of the garment during exercise. There are different factors affecting wool quality parameters both with direct and indirect involvement. The environmental and genetics are the main factors affecting quality and quantity of wool from sheep. Infections related to skin and parasitic infestations have direct influence on the quality of wool. Breed or genotype is one of the main genetic factors that influences the product and productivity as well as quality of wool from sheep that is fleece from different sheep breeds is different in its both physical and chemical characteristics. Hormonal changes in relation to sex of sheep also have effect on the wool quality traits. The main objective of this review was to define and explore key wool characteristics, such as staple length, number of crimp, fibre type, fibre diameter, wool wax and scouring yield in regards to quality and interventions approaches for improving. In most of studies, non-genetic factors such as age, season, shearing period, shearing frequency and nutrition have a significant effect on traits viz.  staple length, wool wax, scouring yield, fibre diameter and for other traits as well. Conducting a research on wool quality characteristics is an  operative way of defining and differentiating the quality of wool. Acquiring knowledge of the wool quality characteristics can help to manage the  end use products, consumers comfort and processing intensity. Therefore, an understanding of the factors affecting physical and chemical properties of wool traits is important to improve the quality of wool through genetics and management interventions. This article reviews some important quality attributes of wool for the product and productivity development and value addition

    Amaranth (Amaranthus spp.) may have potential as a forage for summer grazing in the southeastern United States (US). Six accessions of amaranth were harvested at bud stage in two successive growing seasons to evaluate growth characteristics, yield, and forage quality parameters. The accessions, three genotypes of A. tricolor (Hinchoy VL, RRC-701, RRC-1186) and one each of A. hybridus (RRC-843), A. cruentus (RRC-1034), and A. dubius (RRC-1186) were evaluated in 1994 and 1995 on a Dothan sandy loam (fine loamy, siliceous, thermic, Plinthic Paleudult) soil at the Fort Valley State University Research Station, Fort Valley, Georgia. The plots were planted in mid- June in each year as a randomized complete block with four replications. Plants were harvested approximately 40 d after germination. Plant height and total dry matter (DM) yield determinations were made at harvest. Percentage leaf and stem were determined by hand separation of 5 randomly selected plants from each plot. Leaf material for the 1994 growing season was analyzed for neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude protein (CP) content. Protein content ranged from 240-260 g/kg, while NDF and ADF ranged from 523-587 g/kg and 187-293 g/kg, respectively. The accessions ranged in height from 41-74 cm and total DM and leaf DM yield from 0.83-1.30 Mg/ha and 0.52-0.79 Mg/ha, respectively. All the accessions were over 50% leaf. With adequate yields and high leaf protein, amaranth has potential as a summer forage crop for livestock grazing in the southeastern US

    ntroduction. Gastrointestinal parasitic infections are most prevalent in populations with low household income, poor han- dling of personal and environmental sanitation, overcrowding, and limited access to clean water. We conducted this study to esti- mate the prevalence of parasitic infection and nutritional status, and to evaluate the extent to which the two are associated among schoolchildren in rural Ethiopia. Methods. This is a cross sectional study of 664 students aged from 6 to 19 years old from Angolela, Ethiopia. Socio-demo- graphic information was collected using a structured question- naire. Anthropometric measurements were taken at the time of interview. Examinations of fecal samples for helminthic and pro- tozoan parasitic infections were performed. Logistic regression procedures were employed to evaluate the association between stunting, underweightedness, and wasting with parasitic infec- tions. Results. One-third of the participants were found to have a protozoan infection, while 7.1% were found to have a helminhic infection. Approximately 11% of the students were stunted, 19.6% were wasted, and 20.8% were underweight. Severely underweight boys were 3.88-times as likely as boys of adequate weight (odds ratio OR = 3.88, 95% confidence interval CI: 1.12- 13.52) to be diagnosed with protozoan infections. Among girls, those who were severely stunted were approximately 12 times (OR = 11.84, 95%CI: 1.72-81.62) as likely to be infected with a helminthic parasite, than those who were not. Overall, there was a deficit in normal growth patterns as indicated by lower than average anthropometric measures. Discussion and conclusions. There is a high prevalence of intes- tinal parasitic infections. Stunting, wasting, and underweighted- ness were also prevalent, and showed patterns of associations with intestinal parasitic infections. Efforts should be made to strengthen and expand school and community-based programs that promote inexpensive, though effective, practices to prevent the spread of parasitic diseases. Initiatives aimed at improving the nutritional status of school children are also needed

    Introduction. Poor hygiene practices and inadequate sanitary conditions play major roles in the increased burden of communi- cable diseases within developing countries. This study evaluated the KAP of hygiene among rural school children in Ethiopia and assessed the extent to which proper knowledge of hygiene was associated with personal hygiene characteristics. Methods. This cross-sectional study was comprised of 669 students who were interviewed by trained staff. Participants were in grades 1-6 at Angolela Primary School, located in rural Ethiopia. Data consisted of hygiene and hand washing practices, knowledge about sanitation, personal hygiene characteristics, and presence of gastrointestinal parasitic infection. Results. Approximately 52% of students were classified as having adequate knowledge of proper hygiene. Most students reported hand washing before meals (99.0%), but only 36.2% reporte

    Objective. To evaluate the prevalence of metabolic syndrome (MetS) according to the International Diabetes Federation (IDF) and Adult Treatment Panel (ATP) III criteria among working East African adults. Design. This cross-sectional study of 1,935 individuals (1,171 men and 764 women) was conducted among working adults in Addis Ababa, Ethiopia. The study was conducted in accordance with the STEPwise approach of the World Health Organization. Results. According to ATP III and IDF definitions, the overall prevalence of MetS was 12.5% and 17.9%, respectively. Using ATP III criteria, the prevalence of MetS was 10.0% in men and 16.2% in women. Application of the IDF criteria resulted in a MetS prevalence of 14.0% in men and 24.0% in women. The most common MetS components among women were reduced high-density lipoprotein-cholesterol (HDL-C) (23.2%) and abdominal obesity (19.6%); whilst reduced HDL-C concentrations (23.4%) and high blood pressure (21.8%) were most common among men. Conclusion. MetS and its individual components are prevalent among an apparently healthy working population in Ethiopia. These findings indicate the need for evidence-based health promotion and disease prevention programs; and more robust efforts directed towards the screening, diagnosis and management of MetS and its components among Ethiopian adults

    In the southern U.S.A., annual clovers provide high-quality winter and spring grazing for beef cattle and sheep. New Zealand data on white clover (Trifolium repens L.) suggests that goats do not prefer this plant as much as sheep (Clark et al., 1982) but little data are available on willingness of goats to consume different clover types in the USA

    To evaluate the independent and combined associations of maternal self-reported poor sleep quality and antepartum depression with suicidal ideation during the third trimester METHODS: A cross-sectional study was conducted among 1298 pregnant women (between 24 and 28 gestational weeks) attending prenatal clinics in Lima, Peru. Antepartum depression and suicidal ideation were assessed using the Patient Health Questionnaire-9 (PHQ-9). The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used to assess sleep quality. Multivariate logistical regression procedures were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) after adjusting for putative confounders. Approximately, 17% of women were classified as having poor sleep quality (defined using the recommended criteria of PSQI global score of >5 vs. ā‰¤5). Further, the prevalence of antepartum depression and suicidal ideation were 10.3% and 8.5%, respectively in this cohort. After adjusting for confounders including depression, poor sleep quality was associated with a 2.81-fold increased odds of suicidal ideation (OR=2.81; 95% CI 1.78-4.45). When assessed as a continuous variable, each 1-unit increase in the global PSQI score resulted in a 28% increase in odds for suicidal ideation, even after adjusting for depression (OR=1.28; 95% CI 1.15-1.41). The odds of suicidal ideation was particularly high among depressed women with poor sleep quality (OR=13.56 95% CI 7.53-24.41) as compared with women without either risk factor. This cross-sectional study utilized self-reported data. Causality cannot be inferred, and results may not be fully generalizable. Poor sleep quality, even after adjusting for depression, is associated with antepartum suicidal ideation. Our findings support the need to explore sleep-focused interventions for pregnant women
