The effects of 12 different diets which regulated 0.1-0.7 mol Na/K ratio and 176-422 mEq/kg Dietary Electrolyte Balance, DEB, (Na+K-Cl) were investigated on growth, blood gases, hematological variables, biochemical parameters and carcass traits in broiler chickens. Two-day old Ross-308 male chicks (n=180) having individual thirty replicates for 6 groups were used and the study lasted 42 days in the experiment. The S group diet was based on corn and soybean meal and 0.25% salt. This group diet was accomplished by adding 1-0.5% NH4Cl as A1 and A2 of anionic groups and 0.5-1-1.5% NaHCO3 as C1, C2 and C3 of cationic groups in starter and grower phases, respectively. Increasing Na/K and DEB of the diets had no effect on live weight, body weight gain and feed per gain in 0-42 days (P>0.05). Blood pH quantitatively increased in S, C1 and C2 groups (P<0.05). A1, A2 and S groups of pO(2) levels were higher than those of cationic groups (P<0.05), (R-2=0.59). The values of HCO3-, HCO3std, TCO2, BEecf, Be(b), Hct and THbc were lower anionic groups than cationic groups (P<0.05), (R-2=0.63-0.82). SO2c level was the lowest in C1 group (P<0.05). Anion gaps of the broilers were calculated as 7.97-20.84 mEq/l. Ionized calcium was quantitatively the highest in A1 group. Hot carcass and abdominal fat were not affected by the experimental diets with varying Na/K and DEB (P>0.05). Based on the results of this study, anionic diet such as A1 or 0.1 of Na/K ratio and 212 mEq/kg of DEB could be fed for broilers in case of insufficient Ca. In normal case, it is concluded that C1 and C2 of diets or 0.3-0.5 of Na/K ratios and 259-344 mEq/kg of DEB were appropriate for broilers.
Effects on Performance, Egg Quality Criteria and Cholesterol Level of Adding Different Ratios Flaxseed Oil Instead of Sunflower Oil To Compound Feed of Laying Hens

This study was conducted to examine the effect on performance, egg quality criteria and egg cholesterol level of adding different ratios of flaxseed oil instead of sunflower oil to the compound feed of laying hens. A total of 210, 30-week old Lohmann LSL laying hens were acquired for the study. The study groups consisted of a control group (5% sunflower oil (SO) + 0% flaxseed oil (FO) and trial 1 (4% SO + 1% FO), trial 2 (3% SO + 2% FO), trial 3 (2% SO + 3% FO), trial 4 (1% SO + 4% FO) and trial 5 (0% SO + 5% FO) groups. The study lasted for 8 weeks. The feed consumption was not different among the experimental groups. Feed utilization rate was higher in group 2 compared to those of other between 0-8 weeks (P<0.001). Between weeks 0 to 8, all trial groups were found have significantly higher levels of linoleic acid, one of the fatty acids found in yolk, compared to the control group (P<0.001). Additives were not found to affects levels of cholesterol in yolk, with no significant differences found between groups. In short, sunflower oil and flaxseed oil added to laying hen rations did not create any differences in terms of egg quality criteria or egg cholesterol levels, but higher levels of flaxseed oil added to the rations resulted in linearly higher levels of linolenic acid content of yolk, and use of the two oil additives together increased egg yields.
