四个实验,以确定膳食电解质水平的波动(毫当量Na + K-Cl每公斤)或不同的饮食氯化钠水平会影响性能,水摄入,或鸡的排泄物水分美联储semduramicin vs nonmedicated控制。在所有的实验中,男性商业肉用鸡小鸡被使用,所有的饮食喂养有或没有semduramicin 25毫克/公斤的饮食。基底的饮食是基于玉米、豆粕、石油和家禽。进行了实验1,3,4在电池孵卵器使用男性肉用鸡小鸡18 d的年龄。在实验1中,六个电解质水平美联储(基底(K Cl Na 0.2%, 0.33%, 1.10%);基底Na(氯化钠)+ 0.1%;基底+ 0.1% K(氯化钾);基底Na(碳酸钠)+ 0.2%;基底+ 0.34% K(氯化钾);基底加上0.15% Cl(从氯化铵)]。 There were no significant changes in BW gain, feed consumption, or feed conversion ratio caused by any dietary treatment. Water consumption was not affected by the inclusion of Na, Cl, K, or electrolyte levels, but excreta moisture was affected. The highest and lowest excreta moisture levels came from chicks fed the lowest chloride levels. There were no significant dietary effects on serum Na, Cl, or K by dietary electrolytes or semduramicin. Experiment 2 was conducted with triplicate floor pens of 33 male broilers each for 42 d with four electrolyte levels [basal (0.2% Na, 0.34% Cl, 1.03% K); basal plus 0.1% Na (from sodium carbonate); basal plus 0.1% Cl (from ammonium chloride); basal plus 0.18% K (from potassium carbonate)]. Increasing electrolyte level had a significant effect on BW gain at 35 d but not at 42 d [mainly because of differences in K (1.943 kg at 35 d) vs Cl (2.013 kg at 35 d)]. At 42 d, there were no differences in growth because of N, K, Cl, or semduramicin. Potassium supplementation caused a significant increase in litter moisture (P = 0.031). Semduramicin did not affect litter moisture (P = 0.892), nor were there significant semduramicin interactions with Na, K, Cl, or semduramicin. The basal diets in Experiments 3 and 4 were identical to the basal diet in Experiment 1 except there was no sodium chloride added. The diets fed in Experiment 3 contained 0, 0.1, 0.2, 0.3, or 0.4% added sodium chloride. The diets fed in Experiment 4 contained 0.1, 0.3, 0.5, 0.7, and 0.9% added sodium chloride. The results of Experiments 3 and 4 show that about 0.4% added sodium chloride is necessary to achieve maximum growth and feed conversion. It is clear that semduramicin had no significant effect upon the variation observed in any of the variables measured.
