Item RESPONSE OF BROILER CHICKS TO DIETARY MORINGA SEEDS AND ZIGBIR AS NATURAL GROWTH PROMOTERS(2014) MOHAMED ELAMIN AHMED; Talha ELsadig AbbasAbstract- In a 42-day experiment the effect of moringa seeds and Zigbir on growth performance and carcass characteristics was studied. One hundred twenty, 1day-old, unsexed Ross 308 broilers were purchased from commercial hatchery. The initial live body weight of the chick was (47.00 g ±0.67). The chicks were randomly assigned to 4 dietary treatments containing 3 replicates of 10 birds each. Starter and finisher experimental diets consisted of control, 0.04% zigbir, 0.5% undecorticated moringa seeds UDCM and 0.5% decorticated moringa seeds DCM. Data were analyzed in completely randomized design using the general linear model (GLM) procedure. Feed intake, body weight gain, FCR and PER were not significantly (P≥0.05) influenced by dietary treatments except feed intake during starter phase. Dietary moringa seeds both decorticated or undecorticated significantly (P≤0.05) reduced feed intake during starter phase compared to control and zigbir supplemented groups. However, DCM seeds improved overall body weight gain by 5.58, 5.78 and 10.43%, when compared to control, Zigbir and UDCM seeds group, respectively. During all growth phases, the performance of birds fed dietary zigbir was not significantly (P≥0.05) different versus control. On the other hand relative weight of breast was significantly (P≤0.05) higher for birds fed DCM seeds compared to the others. It was concluded that supplementation of DCM seeds improved growth performance of the broilers.Item Poultry meat quality and welfare as affected by organic production system(2015) Talha ELsadig Abbas; Mohamed Elamin AhmedAbstract: 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.
