| Abstract |
A total number of 200 unsexed one-day old Ross commercial broilers were used to evaluate the nutritional value of taurine supplementation to plant protein diet broiler performances. Chicks were distributed randomly and divided equally into four treatment groups nearly equal in average live body weight. Each treatment was represented by 50 chicks in five replicates (10 chicks each). Two different basal diets were formulated, the first was containing fish and meat meal (animal diet. AD) and fed 10 the first treatment (T1) another one was containing soybean and corn gluten meal as a source of protein in (plant diet.PD) and fed 10 the second treatment group (T2). The third and fourth treatment groups (T3 and T4) were fed the second diet (PD) with taurine addition 0.025 and 0.05% of diet for each treatment (PD+Tu1 and PD+Tu2. respectively), The experimental period lasted forty two days.
Results of this study early indicated that, at the of starting period (21of age) both levels of taurine additional to PD increased significantly (P<0.01) broiler body weight (BW) and body weight gain (BWG) for both of T3 and T4 than those fed the AD (T1) However ,at the end of experiment (42 d of age), chicks fed PD + Tu2 (T4) recorded the highest BW and BWG (2123.89 and 2070.04 g. respectively) comparing with the other treatments. Supplementation broiler PD (T3 and T4) with taurine during growing period (22-42 d of age) and for all excremental period (0 - 42 d of age) improved significantly (P<0.01) ,feed conversion ratio (FCR) comparing with those fed PD (T2).
Addition of both levels of taurine 10 PD significantly (P<0.01) increase relative weights of eviscerated carcass. bursa of Fabricius and pancreas. Relative weights of abdominal fat dissected were significantly (P <0.01) decreased for the broiler fed PD+Tu1 and PD +Tu2 (T3 and T4) comparing with those fed AD or PD (TI and T2). Chemical composition of' chicks meat indicated that taurine supplementation to PD (T3 and T4) significantly (P <0.01) decreased ether extract percentages comparing with those fed AD or PD (T1 and T2) while the crude protein percentages had the opposite trend Additions of taurine to broiler P1) significantly (P <0.01 ) decrease plasma total cholesterol. total lipid concentrations and broiler meat total cholesterol. supplementation taurine to PD significantly (P<0.01) increased digestibility coefficient values of crude protein. ether extract. Crude fiber nitrogen free extract comparing with the digestibility values for the broiler fed PD. Incorporation of taurine in the broiler PD at the highest level (T4, 0.05%) was superior for maximized the net return, economical efficiency (1.373) and relative economical efficiency (103.32) comparing with the other treatments,
conclusion, the investigation clearly indicated that taurine supplementation to broiler plant diets has important role for improve broiler performance blood lipids and profiles and increasing the economical efficiency.
