摘 要:为探究种蛋蛋重对豁眼鹅受精率、孵化率、健雏率、孵化期失重率和公母比例的影响,试验选取32周龄豁眼鹅所产种蛋,测定种蛋的重量,根据蛋重分为4组,分别为A组(120.0~124.9 g)、B组(125.0~129.9 g)、C组(130.0~134.9 g)和D组(135.0~139.9 g),每组5个重复,每个重复60个,每组300个,共1200个种蛋,在同一环境下进行孵化,孵化期为31 d,孵化期结束后,称量所有雏鹅的初生重,并分别计算每个试验组的受精率、孵化率、孵化期失重率、健雏率和公母比例等指标。结果显示:①豁眼鹅种蛋重量整体呈近似正态分布,其中蛋重在125.0~129.9 g区间的种蛋数量最多;②A、B、C组的受精率无显著差异(P>0.05),D组与其他组具有显著差异(P<0.05),各组之间的孵化率差异显著(P<0.05),且B组孵化效果最好;③各组健雏率差异显著(P<0.05),且B组健雏率最高;④蛋重与初生重显著正相关(P<0.05),与孵化期失重率呈显著负相关(P<0.05);⑤各组公母比例差异不显著(P>0.05)。研究表明,豁眼鹅种蛋重量在125.0~129.9 g时孵化率和健雏率较高。This experiment was conducted the effects of egg weight on fertilization rate,hatching rate,healthy goslings rate,weight loss rate during incubation period and and male-to-female ratio of Huoyan goose.The eggs laid by the 32-week-age Huoyan goose were selected and the weight of the eggs was weighed.Then,the eggs were divided into 4 groups,group A(120.0-124.9 g),group B(125.0-129.9 g),group C(130.0-134.9 g)and group D(135.0-139.9 g)with 5 replicates each group and 60 eggs each repeat,300 eggs each group and 1200 eggs in total.The incubation period was 31 days under the same environmental conditions.After the incubation period,the birth weight of all the goslings was weighed,and the indicators such as fertilization rate,hatching rate,weight loss rate during incubation period,healthy goslings rate and male-to-female ratio of each experimental group were calculated.The results showed as follows:①The egg weight of the geese was approximately normal distribution,and the number of eggs weighing in the range of 125.0-129.9 g was the most.②There was no significant difference in fertilization rate between groups A,B and C(P>0.05),but there were significant differences between group D and other groups(P<0.05).There were significant differences in hatching rate between different groups(P<0.05),and group B had the best incubation effect.③There were significant differences in the healthy goslings rate between different groups(P<0.05),and group B was the best.④There was significant positive correlation between egg weight and birth weight(P<0.05),and significant negative correlation with weight loss rate during incubation period(P<0.05).⑤There was no significant difference in the rate of male and female among the groups(P>0.05).Therefore,the hatching rate and healthy goslings rate of breeding egg of Huoyan goose breeding egg between 125.0 g to 129.9 g was better.
