(2016) Mohamed Elamin Ahmed; Tamadur Ali Eltayb Algam; Talha Elsadig Abbas
Abstract The present experiment was conducted to investigate the effect of different levels of cinnamon powder (0.0, 0.25, 0.50 and 0.75%) on broiler performance and carcass characteristics. One hundred and sixty, 1 day-old, unsexed broiler (Ross 308) weighed (48.1 g ±1.7) were randomly assigned to 16 floor pens (1m2 each) with wood shavings. The four isocaloric and isonitrogenous starter and finisher diets were formulated according to nutrient specifications of national research council (NRC.1994). Feed intake, live body weight, body weight gain, FCR and PER were determined for each pen. At the end of the experiment (6 weeks of age) two birds from each pen were randomly selected, weighed and manually slaughtered for carcass characteristics and internal organ determination. Data were analyzed in completely randomized design using the general linear model (GLM) procedure. Growth performance parameters except body weight gain, FCR and PER during starter phase were not significantly (P≥0.05) influenced by the dietary treatment. Body weight gain was significantly (P≤0.05) reduced for birds fed 0.50% cinnamon powder versus those fed control and 0.25%. FCR and PER for birds fed 0.50% and 0.75% cinnamon powder were significantly (P≤0.05) poorer than control. Most of the carcass traits and internal organs weights were not significantly (P≥0.05) affected by the dietary treatments. It can be concluded that inclusion of cinnamon powder up to 0.75% had no growth promoting effect on broiler chickens.

Effect different fat sources on performance and carcass characteristics of broilers
(2017) Mohamed Elamin Ahmed; Talha Elsadig Abbas
Abstract An experiment was conducted to evaluate the effect of dietary fat source on broiler performance and carcass characteristics. Ninety one day-old unsexed Ross 308 broiler chicks were purchased from a commercial hatchery. Chicks used in this study had uniform initial live body weight (44.31g ±0.90). The chicks were randomly allotted to 9 pens (1mx1m) in groups of 10 chicks in a pen. The chicks were divided into three dietary treatments; each group was replicated three times. The birds were fed on starter and finisher experimental diets containing vegetable oil (A), hydrogenated vegetable oil (B) and beef tallow (C). At the end of the experiment (42 days), 2 birds per replicate were randomly selected for carcass characteristics and internal organs evaluation. The results revealed that different sources of fat had no significant (p≥0.05) effect on live performance parameters during different growth phases. However, body weight gain during starter phase (0-3 weeks), was significantly (p≤0.05) higher for birds fed dietary hydrogenated vegetable oil and beef tallow versus those fed vegetable oil. During the finisher phase (4-6 weeks), broilers fed hydrogenated vegetable oil grew faster by 13.9 and 12.0% versus those fed vegetable oil and beef tallow, respectively. In addition, FCR and PER of broilers fed dietary hydrogenated vegetable oil were improved by 12.3 and 12.4%, respectively as compared with those on dietary beef tallow.

(2011) Mohamed Elamin Ahmed; Khadiga Abbas Abdelati
Abstract: This experiment was carried out to assess the effect of feeding leucaena seeds supplemented with choline on broiler chicks’ performance. Two levels of choline chloride (0, 0.1%) were added to three levels of leucaena seeds (0, 6 and 12%) and incorporated in broiler starter and finisher diets. All performance parameters were depressed with the inclusion of leucaena seed diets. PCV% of birds fed any level of leucaena seed diets was not significantly different compared to control. Plasma GOT, ALP, Na, Pi, K and globulin were not affected by the dietary treatments. Plasma cholesterol of birds fed leucaena seed diets was significantly lower than that of control. Leg score of birds fed leucaena seed diets was significantly (p<0.05) poorer compared to the control except for birds fed 6% choline supplemented leucaena seeds

Effect of different dietary levels of vitamin C on Performance and carcass characteristics of two broiler strains in arid hot conditions
(جامعة النيلين, 2017) Mohamed Elamin Ahmed; Mazen Nasssir Ali Nassir; Omer Abdul Mageed Sallam
Abstract: This experiment was conducted to investigate the responses of two broiler strains Ross 308 and Cobb 500 to 4 levels of vitamin C (0,150, 200 and 250 mg per 1 kg feed). One hundred and twenty - one day old chicks of each strain were used in this study. The experiment was extended for 6 weeks, during which starter feeds were fed for the first 3 weeks and finisher feeds were given then after. The experiment was conducted in an open- sided house at Khanfar area, Abyan district (Yemen). Birds were randomly assigned to the treatments with 3 replicates and 10 birds each. Weekly live body weight, feed intake, body weight gain, feed conversion ratio (FCR) and production yield Kg/m2 were recorded. At 42 day of age, three birds from each pen were randomly selected and slaughtered for carcass characteristics. In addition body temperatures and some blood constituents were also studied. A split plot design was used in which 2 main plots (strains) were fed the 4 levels of vitamin C as sub plots. Data were analyzed by the general linear model (GLM) procedure. Duncan’s multiple range test was used to compare the treatment means. The results revealed that Cobb 500 was significantly (p≤ 0.05) superior versus Ross 308 in term of live body weight, feed intake, body weight gain, FCR and dressing out %. However, Ross 308 showed significantly (p≤ 0.05) higher relative weights of heart, liver and gizzard than Cobb 500. With the increasing levels of vitamin C, live body weight, FCR, livability% and production yield kg/m2 weresignificantly (p≤0.05) improved. Moreover, feed intake was numerically increased at 250 versus 0 mg vitamin C. Strain had no significant (p≥ 0.05) effect on body temperature. Nevertheless, supplementation with 200 mg vitamin C/kg feed significantly (p≤ 0.05) reduced body temperature compared to 0 and 250 levels. Supplementation with different levels of vitamin C had significantly (p ≤ 0.05) increased serum protein compared to non-supplemented one. Serum uric acid was significantly (p≤ 0.05) reduced at 200 and 250 mg vitamin C versus control.

Effect of feeding graded levels of ginger on performance and carcass characteristics of broiler chicks
(2017) Tamador Ali Eltayb Algam; Mohamed Elamin Ahmed
An experiment was conducted to determine the effect of ginger root powder additives on growth performance and carcass characteristics of broiler chicks. One hundred and sixty unsexed one day-old (Ross308) broiler chicks were used in this study. Ad libitum feeding system was applied during the two rearing periods, starter period for 3weeks and finisher period for other 3weeks. The broiler chicks were randomly divided into four groups, each represented a treatment (40 birds/treatment) with 4 replicates in a completely randomized design. Four experimental rations were formulated to meet requirement for essential nutrients for broiler chicks according to NRC (1994) recommendation. These rations contain four graded levels of ginger root powder 0%, 0.25%, 0.50% and 0.75%. The experiment lasted for six weeks. Results showed no significant (P≥0.05) differences in overall feed intake, live body weight and weight gain among all dietary treatments. Birds fed on 0.50% ginger showed significant (P≤0.05) deterioration in feed conversion ratio FCR and protein efficiency ratio PER during finisher and overall period when compared with control. However, birds fed on 0.25 and 0.75% were not significantly (P≥0.05) different versus control. Dietary treatments had no significant (P≥0.05) effect on most carcass characteristics and internal organs. The results showed that the
Effects of Dietary Levels of Methionine on Broiler Performance and Carcass Characteristics
(2011) Mohamed Elamin Ahmed; Talha E. Abbas
Abstract: The present experiment was carried out to determine the effect of dietary methionine levels higher than NRC recommendation on broiler performance and carcass traits. Four dietary levels of methionine 0, 100, 120 and 130% of NRC recommendation were used. Dietary levels of methionine, expressed as percentage of NRC recommendations, significantly (p<0.05) affected feed intake, Feed Conversion Ratio (FCR) and Protein Efficiency Ratio (PER). Feed intake was numerically improved with 110 and 130% of NRC methionine, but was not improved by 120% NRC methionine. Body weight gain was significantly (p<0.05) improved by 110 and 130% of NRC methionine compared to the control. The broiler chicks on methionine higher than NRC showed significant (p<0.05) increase in absolute and relative weight of breast and significant (p<0.05) decrease in abdominal fat.
Poultry meat quality and welfare as affected by organic production system
(2015) Talha ELsadig Abbas; Mohamed Elamin Ahmed
Abstract: Most of consumers preferring organic food accompanied emerge of environmental awareness in the last decades. Organic production system is considered as an important solution for the environment problems because it improves sustainable agriculture by using organic compounds and avoiding synthetic chemical ones, restricting intensive production and making the entire chain of production under control. Therefore, it is encouraged and supported by environmental protection agencies in spite of the higher production cost of organic production compounds. Due to its higher production cost most producers prefer intensive systems because they focus on reducing cost and increasing production regardless of environmental degradation. Organic poultry system usually mentioned with free-range system and poultry welfare. That is because all organic systems are free-range. Organic system gets a lot of attention of animal welfare organizations because it assists birds to express normal behavior by offering plenty space. Organic or free-range system by some modifications and developing of the system regarding good management of its environment in addition to establishment of biosecurity measures it could considered as a suitable system for human, poultry and environment rather than intensive system because it achieves human health by avoiding dangerous remainders in food such as chemical residues, and for poultry by offering good welfare and health, and also to environment by improving sustainable agriculture.
