摘要
为研究在马冈鹅养殖中添加青饲料对育雏期(1-28日龄)雏鹅生长性能的影响,该试验随机选取100只同一批出雏的1日龄健康马冈鹅,随机分成试验组和对照组,每组5个重复,每个重复10只,饲养至28日龄。试验期间两组皆采取自由饮水和自由采食;对照组只饲喂配合饲料,试验组饲喂配合饲料和青饲料。试验期记录雏鹅成活率、日采食量、测定体重和体尺、计算料重比。结果发现在d 1-d 14期间,两组雏鹅体重、日增重和料重比无显著差异(P>0.05);而在d 15-d 28期间,试验组的料重比显著低于对照组(P<0.05),日增重显著高于对照组(P<0.05),d 21和d 28的体重也显著高于对照组(P<0.05)。两组肉鹅体尺在育雏前期无显著差异(P>0.05),但在d 28时,试验组各个体尺指标均高于对照组(P<0.05)。结果表明,马冈鹅育雏阶段添加青饲料,可促进雏鹅的生长发育,降低精饲料的消耗。该试验为马冈鹅规模化养殖的青饲料添加提供参考,但是具体青饲料的添加量和比例,以及其对后续育成期肉鹅的影响仍有待进一步探究。
To investigate the effects of green forage on growth performance of Magang Goslings(1-28 days old),100 healthy Magang goslings(1-day old)from the same batch were randomly divided into experimental group and control group(n=50)with 5 replicates per group and 10 geese per replicate,and were fed until 28 days of age.During the experiment,both groups were provided with ad libitumaccess to feed and water,and the experimental group was fed a diet that included both formula feed and green forage,while the control group was fed only formula feed.The survival rate,daily feed intake,body weight and body size of goslings were recorded,and the ratio of feed to weight was calculated.The findings indicated no significant differences in body weight,daily gain and feed to gain ratio between the two groups during the initial 1-14 days.However,from day 15 to 28,the feed to gain ratio of the experimental group were significantly lower than those of the control group(P<0.05),while daily weight gain and the body weight of d21 and d28 was significantly higher than that of the control group(P<0.05).There was no significant difference in body size between the two groups at the early stage of brooding,but at d28,the individual size indexes of the experimental group were higher than those of the control group(P<0.05).The results showed that the addition of green forage in the brooding stage of Magang geese could promote the growth and development of geese and reduce the feed-to-weight ratio.This experiment provides a reference for the addition of green forage in large-scale breeding of Magang geese,but the amount and proportion of specific green forage added and its impact on subsequent breeding geese still need to be further explored.
