SPF鸡育雏期加热方式的选择
Selection of heating method for SPF chickens during their breeding period
摘要
Abstract
This study was to compare three key indicators that could measure the qualities of chick rearing,namely survival rate,weight gain,and body weight uniformity;and to select a heating method that would be more favorable for the growth of SPF chicks.480 1-day-old SPF chicks were used and divided into 4 groups,with 3 replicates in each group and 40 chicks in each replicate.The chicks were placed in i-solation devices using heating methods such as curling tube(the curling tube group),yellow light infrared bulb(the yellow light group),warm air fan(the warm air group),and red light infrared bulb(the red light group);and they were raised until 28 days of age.In the rea-ring period(0-4 weeks of age),the survival rate,average weight gain,and body weight uniformity of the chicks were recorded weekly.The results were as follows:The 4-week survival rate of the yellow light group was 95%,while the 4-week survival rate of the other 3 groups was 100%,indicating that the yellow light group had the lowest survival rate.In terms of weight gain,the 4-week cumulative weight gain of the curled tube group and the warm air unit group was significantly higher than the other two groups(P＜0.05).In terms of weight uniformity,both the warm air groups and the red light group were 80%,higher than that of the other two groups.To determine the cause of the differ-ences,the average temperature,temperature uniformity,and average illuminance inside each group of the isolators were tested.The results showed that there was no significant difference in the average temperature among the four groups(P＞0.05),but the maximum temperature difference in the curved tube group was significantly greater than that in the other three groups.In terms of average illumination,the yellow and red light groups were significantly higher than the curved tube group and the warm air unit group(P＜0.05).The comparative study of the indicators herein suggested that the warm air unit had good temperature uniformity,optimal light intensity,high survival rate,average weight gain,good weight uniformity,and did not harm the occupational health of the breeder,and this heating method was also safe and eco-nomical.It would be an ideal heating method for raising SPF chickens.关键词
