  • Chemical Analysis and Tannin Content of Some Raw and Germinated Sudanese Local Varieties of Sorghum and Their Potential as Poultry Energy Feed Source for Food Security in Rural Areas

To reduce poultry feed cost and to alleviate the competition between man and poultry in energy source, the current study has been carried out to evaluate the chemical composition of some Sudanese sorghum varieties and their nutrient potential as feedstuffs. Three Sudanese sorghum varieties Feterita, Wad Ahmed and Mogod were brought from cereal grains markets of Khartoum and Janub Kurdufan states and subjected to proximate analysis and tannin content determination. Mineral content of Feterita and Mogod was evaluated and Wad Ahmed tannin content was assessed after five days of germination. The proximate analysis of Feterita, Wad Ahmed and Mogod showed the following composition: crude protein% (CP) 16.65, 11.03 and 16.24, crude fibre% (CF) 1.97, 2.44 and 3.06, fat% 3.86, 2.81 and 3.88 and metabolizable energy MJ/kg (ME) 14.25, 14.48 and 13.49, respectively. Calcium and phosphorus content values for wad Ahmed and Feterita were 0.03 and 0.41 and 0.02 and 0.32%, respectively. Feterita lysine and methionine concentrations were 0.3501 and 0.2925%, respectively. The percentage of tannin of Wad Ahmed was 0.1379%. Germination of Wad Ahmed seeds increased tannin content by six times. The same pattern of increasing was observed for fibre content of Wad Ahmed germinated seeds. The results indicated that sorghum variety Mogod could be used as alternative energy source with Feterita and Wad Ahmed. Because Wad Ahmed and Feterita are preferred to be consumed by man in rural areas and their production and prices are fluctuated according to rainy season. Moreover, Mogod is characterized by high disease tolerance and capability to be produced in very harsh climatic conditions.

  • Effect of sexing and dietary incorporation of sugar cane molasses on broiler performance and carcass characteristics

Sorghum is used as a source of energy in poultry rations in Sudan, in spite of its high price and competition between humans and animals. There are several alternatives for sorghum grains such as sugar cane molasses which is available and cheap source of energy as agro-industrial by-product. The unsexed one-day old broiler chicks are commercially used in Sudan. The data concerning the performance of male broiler chicks in comparison with unsexed one are lacking and need to be investigated. The objectives of the study were to evaluate the effect of partial replacement of sorghum grains by cane molasses on broiler performance and to compare the performance of male broiler chickens with unsexed one. A (2 × 3) factorial arrangement was used in a completely randomized design to study the effect of two sexing pattern (male and unsexed chicks) and three dietary levels of molasses (0, 10 and 24%) on broiler performance. A total of six treatments were employed and each treatment was replicated three times with six birds each. The experiment lasted for 42 days. Feed consumption, weight gain, and feed conversion ratio (FCR) were recorded. At the end of the experiment, two birds from each experimental unit were selected according closed to average weight and slaughtered. Carcass weight, weights of some internal organs and cuts were measured. Blood samples were collected for determination of cholesterol, triglycerides, protein and potassium. The results revealed that significant improvement (p≤0.05) in feed consumption, body weight gain and FCR as the level of molasses increased. The greater feed consumed and the highest weight gain were observed with birds fed on diets incorporate with 24% molasses. Males were better in weight gain and feed consumption than unsexed birds, while no differences in FCR. The greater blood protein and potassium levels were recorded with birds fed 24% molasses. Sexing had no significant effect (p≥0.05) on blood constituents. The weights of carcass, thigh, drumstick and breast were not affected by experimental treatments. The current study concluded that, the sugar cane molasses could be used as alternative energy source up to 24% in broiler diets without negative impact in performance and male were advisable to be adopted for commercial broiler production than unsexed one. Economically, the cost of diets containing 10 and 24% molasses were lower than control one.

  • الضغوط النفسية لدى معلمي مرحلة الأساس وعلاقتها ببعض المتغيرات (دراسة ميدانية بمدينة المناقل،ولاية الجزيرة، السودان)

هدفت الدراسة للتعرف على مستوى الضغوط النفسية لدى معلمي مرحلة الأساس بمدينة المناقل، والتعرف على الفروق في الضغوط النفسية لديهم في كلٍ من متغيري النوع وسنوات الخبرة. اتبعت الدراسة المنهج الوصفي. طبقت الاستبانة على عينة بلغت (140) معلما ومعلمة اختيرت بالطريقة العشوائية البسيطة. استخدم برنامج الحزم الاحصائية للعلوم الاجتماعية ( SPSS) لتحليل البيانات. توصلت نتائج الدراسة إلى أن مستوى الضغوط النفسية لدى معلمي مرحلة الأساس منخفض ومنخفض جدا، توجد فروق ذات دلالة إحصائية في الضغوط النفسية لدى معلمي مرحلة الأساس ترجع لمتغير النوع لصالح (المعلم) ومتغير سنوات الخبرة لصالح الفئة (1-5) سنوات.
