  • Mode of action and determination of antioxidant activity in the dietary sources: An Overview
Determination of antioxidant/capacity in the dietary, food, drugs, and biological samples is an interesting approach for testing the safety of these compounds and for drug development. Investigating the google searching engines for the words (measurement + antioxidant + capacity) yielded more than 20 million results, which makes it very difficult to follow. Therefore, collecting the common methods to measure the antioxidant activity/capacity in the food products and biological samples will reduce the burden for both the students and researchers. Nowadays, it is widely accepted that a plant-based diet with a high intake of dietary sources such as vegetables, fruits, and other nutrient-rich plant foods may decrease the effect of oxidative stress-related diseases. In this review article, we have provided the most recent advances in the most common in vitro methods used for evaluating the antioxidant potential of numerous food products, plant extracts, and biological fluids. We have also provided detailed procedures on how to perform them and analyze the results. This review article shall be a comprehensive reference for all techniques used in this area.

  • Economic impact of natural gastrointestinal parasitic infection on fattening performance of Sudan desert sheep (experimental trial)

This study was conducted to evaluate the impact of natural gastrointestinal parasitic infection on growth and economics production of Sudan Desert sheep. Forty-eight naturally infected lambs were divided into 2 groups of 24lambs each. One group was treated for internal parasites while the other was left naturally infected. Each group was then divided into two groups according to age (old two years and young milk teeth) and dietary energy level (high and low). The design ended up with eight groups of 6 individuals each which were The design ended up with eight groups of 6 individuals each which were old treated high energy (OTHE), old infected high energy (OIHE), old treated low energy (OTLE), old infected low energy (OILE), young treated high energy (YTHE),young infected high energy (YIHE), young treated low energy (YTLE) and young infected low energy (YILE). They were then fattened for 60 days during which feedlot performance, mortality rate, purchase prices, sales and margins were calculated. The growth parameters as average daily gain and final body showed significantly (P< 0.001) high differences among treatments. Margin percent of sales of (OTHE) was 23.80% while (OILE) lost 40% of their total cost. Although (YTHE) ranked second in term of performance, but they achieved the best profit which was 5.7% more than the profit of (OTHE) because of less dry matter consumption. The number of sold lambs for (OILE) and (YILE) decreased by 50% due to mortality. Total margin of (OTHE) was 98.08 $, while (OIHE) was sold for 36.36% less profit. The former group gained 82.81% more profit than (OTLE). Although older treated lambs gained more weight than younger ones but economically younger lambs were more profitable. Total sales revenue of (OTHE) was 510 $ with 19.2% total margin, while the total sales revenue of (YTHE) was 480 $ achieving 24.9% total margin.

  • Effect of Compensatory Growth on Carcass Characteristics of Sudanese Desert Lambs

This study was conducted to detect the effect of compensatory growth on carcass characteristics of the Sudanese desert lambs. Twelve lambs (Hamri ecotype) of the same initial weight (23±16 Kg) were used in this experiment. The animals were randomly divided into two groups. The first group (A) was adlibitum offered a high energy diet (10. 50 MJ/Kg DM) for 60 days. While the second group (B) was given a low energy diet (8.03 MJ/Kg DM) throughout the same period (60 days).Lambs of the second group were found just to maintain their weight. After that period the lambs from the second group were offered the high energy diet (10. 50 MJ/Kg DM) until they reached the final weight obtained by the first group. It spent 45 days to reach that weight. At the end of the experiment four animals from each group were chosen randomly for slaughter to obtain carcass data and physical and chemical meat analysis. The results showed that hot and cold carcass weights, dressing percentage were not significantly different between treatments. Similarly dressing percentage was not significantly different between treatments. Body components were not significantly different between treatments except mesenteric fat which was significantly (p<0.05) higher in rehabilitated lamb group. The proportion of muscle and fat were significantly greater in the rehabilitated lambs than in free fed lambs. Meat chemical analysis were not significantly different between the two groups, however the fat was significantly (p<0.05) greater in rehabilitated lamb group. Meat quality attributes showed significantly higher colour co-ordinates (L) and (a) and superior water holding capacity in rehabilitated lambs group than in free fed lamb group.

  • Effect of Gastrointestinal Parasites and Dietary Energy Level on Sheep

All praises and thanks are due to Almighty and majesty Allah and Peace be upon all His prophets. May Allah make this effort solely for His sake and accept it. What is the recompense for someone who put his great knowledge, keen advices and patience before a student!?!. With deep respect and sincerity I express my appreciation and gratitude to the compassionate and concerned Professor Salih Ahmed Babiker for his wise and kind supervision rather than encouragement and guidance throughout the PhD course. The far above the ground skies will by no means be reached or replaced. Prayers and wishes that, at all times he stays well and sound. With pleasure and good cheer I admire Professor Hamid Sulieman Abdalla for his excellent and brilliant assistances, understanding and sound judgments. Thanks to him for his patience, kindness plus full of pity and great help. I cannot offer enough thanks or remuneration to Dr. Adil Elkhidir Bala for his constant and continuous support, except praying humbly and earnestly, for Allah to attain him full health and success. Professor Amir Mohammed Salih the scientific father of all, I admire his unlimited support throughout the PhD course.
