本试验旨在研究低硒日粮对蛋鸡行为和血液中某些化学成分的影响。本试验选用12只76周龄产蛋鸡，研究了产蛋鸡血液成分与行为模式的关系。在前2周期间，给母鸡喂食对照饮食，之后将它们分成两组，每组6只母鸡。在接下来的4周内，一组喂食低硒饮食，另一组喂食对照饮食。用VTR记录母鸡行为的昼夜模式的变化，在对照饮食期间持续3天，在低硒饮食开始后的第3周和第4周期间持续3天。低硒日粮下，采食时间和每分钟采食量的比例呈增加趋势，日采食时间显著增加。在这种饮食中，啄食时间比喂食时间少。低硒饲料可显著降低血清甘油三酯和葡萄糖水平，显著升高血清总胆固醇和高密度脂蛋白胆固醇水平。
This study was done to investigate the effects of low selenium diet on the behavioral patterns and some chemical constituents of the blood in laying hens. The relationships between the behavioral patterns and the blood constituents of the laying hens were also studied.Twelve laying hens, 76 weeks old, were used. The hens were fed a control diet during the first 2 weeks, after which they were divided into two groups of 6 hens each. One group was fed a low-selenium diet and the other was fed the control diet during the next 4 weeks. Changes in the diurnal patterns of the behavior of the hens were recorded with VTR for 3 days during the control diet and for 3 days periods during weeks 3 and 4 after the start of the low-selenium diet. The changes in serum constituents were also measured.On the low-selenium diet, the proportion of time spent for feed intake and the feed intake per minute tended to increase and the time spent pecking at feed per day increased significantly. The proportion of time spent pecking other than at feed decreased with this diet. Disturbed behavior decreased and the preening increased significantly with this diet.Triglycerides and glucose in the serum decreased and both total cholesterol and HDL-cholesterol in the serum increased significantly with the low-selenium diet.
