Abstract
Plant origin feeds contain some important nutrients that are not available to poultry due to their inability to analyze them and benefit from them. An experiment was fulfilled to study the performance of broiler chicken using supplemented diets with four levels of phytase enzyme 0.0 FTU/kg feed (T1), 500 FTU/kg feed (T2), 1000 FTU/kg feed (T3) and 1500 FTU/kg feed (T4). A completely randomized design (CRD) using four treatments, with three replicates each with 12 Ross 308 male chicks, was performed. Results indicated significant (P≤0.05) differences in feed intake (FI), body weight (BW) and feed conversion ratio (FCR). The highest feed consumption was recorded with (T1), where (T4) recorded the highest body weight and best FCR followed by (T3, T2 and T1) respectively. There were significant (P≤0.05) differences in carcasses, gastrointestinal tract (GIT) and the associated parts weights, and some GIT organs lengths. However, other parts including heads, necks, shanks and abdominal fat weights were non-significantly (P>0.05) different. There were no significant (P>0.05) differences in individual sensory evaluation attributes (taste, flavor, color and tenderness), but there were significant differences in overall sensory evaluation. There were no significant differences in the mortality rates among treatments. However, there were significant (P≤0.05) differences in the economics appraisal were (T4) recorded the least cost and the highest revenue. It reveals that using the (1500FTU/kg) level of phytase enzyme had performance parameters and economic appraisal. It could be concluded that supplementing broiler chicken diets with (1500FTU/kg) is good for production performance and returns.
Highlights
Feed cost in any system of poultry production compromises the highest expense that accounts for up to 70% of total production costs
Broiler performance Results of supplementing broiler chicken diets with different levels of phytase enzyme on performance are shown in Table 2, significant differences (P≤0.05) were found in feed intake (FI) during the entire experimental period
Broiler Performance This study showed that the different levels of phytase had significantly better performance in feed intake, live
Summary
Feed cost in any system of poultry production compromises the highest expense that accounts for up to 70% of total production costs. Phosphorus is an important mineral in the growing and development of poultry. Necessary to supplement poultry with the adequate amount of phosphorus This phytic acid often forms the complex with other cations such as calcium and proteins which hinder the efficiency of absorption. Phosphorus (P) in phytic acid is of very importance because it has high amount of P accounts to (28.2%), and poultry usage to phytate P is poor (Ravindran et al 2006). Phytase is an enzyme that initiates phosphate removal of from phytate and it has been widely used in animal feeding in the poultry industry to increase phosphorus intake and minimize pollution of environment (Daniel et al 2018). Phytase is an enzyme that can hydrolyze phytate into inorganic P (Selle et al 2007), and because there is insufficient quantity or lack of intestinal secretion to phytase, large amounts of P are excreted in manure and feces causing environmental problems, especially in areas of intensive poultry enterprises
