不同品种、并仔数和温度对肉鸽生产性能的影响

Effect of Different Breeds,Number of Nurturing Squabs and Temperature on Production Performance of Pigeons

通过使用5个生产中应用较为广泛的品种,在自然产蛋、孵化后给予不同数量的雏鸽哺喂,探究品种、带仔数和温度对窝料肉比的影响,同时分析不同带仔数对亲鸽体质量、受精率和产蛋间隔的影响。选取5个品种(组合),每组24对,分别带仔1、2、3、4只,测定生产性能。结果显示,不同的带仔数对公鸽体质量变化、母鸽体质量变化、28日龄乳鸽成活率都产生了显著影响(P<0.05);窝料肉比,带1只仔(7.58)极显著大于2、3、4只(P<0.01),2只(4.75)极显著大于3(3.95)、4只(3.75)(P<0.01),3只、4只差异不显著(P>0.05)。产蛋间隔4只(43.8d)显著大于3(37.4d)、2(35.4d)、1(33.8d)只(P<0.05)。随着环境温度逐渐降低,窝料肉比逐渐增大,差异显著(P<0.05)。品种对窝料肉比没有产生影响。生产中带3只仔较为适宜,在温度较低的地区冬季需做好防寒保暖工作。

To explore the effect of breeds, nurturing squab numbers and temperature on nest feed conversion ratio and simultaneously analyze the effect of nurturing squab numbers on parent pigeon weights, fertilization rate and laying intervals, 5 widely used breeds of pigeons which were nurtured different squab number under the condition of nature laying and hatching in this research, In each breed24 pair pigeons nurturing1,2, 3, and 4 squabs were chosen to measure the production performance, respectively.The results showed that different numbers of nurturing squabs had a significantly effect on parent pigeon weight changes and survival rate of28-day squabs ( P <0.05).The nest feed conversion ratio of breeds nurturing 1 squab (7.58) was great significantly higher than those of nurturing2,3, and 4 squabs ( P <0.01), breeds nurturing2 squabs (4.75) was great significantly higher than those of nurturing 3 (3.95) and 4 squabs (3.75)( P <0.01), and there was no significant difference between breeds nurturing 3 and 4 squabs ( P >0.05).Laying intervals of breeds nurturing 4 squabs (43.8 d) were significantly higher than those of nurturing 3 (37.4 d),2 (35.4 d), and 1 (33.8 d) squabs ( P <0.05).Nest feed conversion ratio significantly increased with the decrease of environment temperature ( P <0.05) and there was no significant difference in nest feed conversion ratio of different breeds.In production, nurturing 3 squabs of parent pigeons is appropriate and cold protection and keeping warm should be prepared in some cold areas in winter.
