Influence of sodium, chloride and calcium level and their interaction on performance and deformity of tibia bone of broiler chicks
Abstract: The present study was conducted to evaluate the response of broiler chicks to different dietary Na+ (0.20 and 0.30%), CI- (0.20 and 0.30%) and Ca (0.90 and 1.20%) levels in (2 x 2x2) factorial arrangement. Dietary electrolyte balance (DEB) was (240,268,283 and 312mEq/kg) at starter period and (232, 260, 267 and 304mEq/kg) at grower period Potassium (K) level was fixed at 0.93% (starter) and 0.90% (grower). A total number of 240 unsexed one-day old Arbor Acers broiler chicks were distributed into 8 treatments of 30 chicks each in three replicates (10 chicks each). Diets were formulated to contain 23% CP and 3100 Kcal ME/Kg (starter) and 18.5% CP and 3200 Kcal ME/Kg (grower).
Results indicated that increasing Na+ level from 0.20 to 0.30% insignificantly improved body weight gain (BWG), feed conversion (FC) at 3 weeks of age and significantly reduced dried tibia weight (DTW), tibia bone ash %( TBA), tibia bone calcium% (TBC) and tibia bone phosphorus% (TBP). Chicks fed diets containing Na 0.30% and Cl 0.30%, with low level of Ca (0.90%) recorded higher BWG at 6 wks of age. Also, chicks fed diets containing Na 0.30% and, Cl 0.30%, irrespective of Ca level recorded the higher BWG and best FC at 3 wks of age. BWG was insignificantly reduced and FC was worsened with increasing Ca % at 3 and 6 wks of age, except for BWG which was significantly reduced with increasing Ca % in the diet at 6 wks of age. Carcass characteristics, excreta moisture and some blood plasma constituents (sodium, chloride, calcium or phosphorus) were not significantly affected by different dietary levels of sodium, chloride or calcium. However, excreta moisture was significantly increased and dried tibia weight (DTW), tibia bone ash %( TBA), tibia bone calcium% (TBC) were significantly reduced with increasing Cl level in the diet. Moreover, chicks fed diets containing higher level of Ca (1.20%) had significantly higher level of plasma calcium, phosphorus and sodium than those fed low level of Ca (0.90%). Increasing Ca level from 0.90 to 1.20% significantly reduced DTW. TBA% and TBC%. The highest relative economic efficiency (REE) was recorded for chicks fed diet T2 containing (0.20/0.30/0.90%) and diet T8 containing (0.30/0.30/1.20%) for. Na+, Cl- and Ca, respectively. In conclusion, the results of the present study the recommend dietary requirements of 0.20 to 0.30% Na+, 0.20 to 0.30% Cl- both with 0.9% Ca during starter and grower period, respectively, without an adversely effects on the broiler performance.
