【摘要】：我國是世界蛋鴨養(yǎng)殖大國,有著豐富的品種資源。蛋鴨養(yǎng)殖需要豐富的水、土地、人力等資源,江西作為水資源豐富然蛋鴨品種資源匱乏的農(nóng)業(yè)大省,研究培育本省蛋鴨品種、提高資源利用率和生產(chǎn)效率對我省農(nóng)業(yè)養(yǎng)殖發(fā)展具有重要意義。本研究主要進(jìn)行荊江鴨、山麻鴨和紹興鴨三個麻鴨品種的體重、體尺和蛋品質(zhì)測定分析,同時進(jìn)行籠養(yǎng)山麻鴨人工授精技術(shù)研究,為下一步籠養(yǎng)蛋鴨選育提供數(shù)據(jù)支持。大部分的測定工作在江西天韻種鴨場進(jìn)行,蛋品質(zhì)測定在江西農(nóng)業(yè)大學(xué)完成。主要研究結(jié)果如下:1、測定荊江鴨、山麻鴨、紹興鴨三品種鴨各周齡體重,用三種非線性模型(Logistic、Gompertz、Von bertalanffy)對不同品種生長發(fā)育進(jìn)行擬合分析。發(fā)現(xiàn)其中山麻鴨和荊江鴨Logistic模型綜合表現(xiàn)更優(yōu),紹興鴨則Gompertz效果更佳;同時也對荊江鴨、山麻鴨和紹興鴨進(jìn)行χ2擬合優(yōu)度檢驗,發(fā)現(xiàn)荊江鴨和紹興鴨采用Gompertz模型分析可以獲得較優(yōu)擬合度。2、測定荊江鴨、山麻鴨、紹興鴨三品種鴨體重和體尺,通過回歸分析建立三品種蛋鴨回歸方程,荊江鴨:Y=-446.850+92.891X4+154.873X6,山麻鴨:Y=-714.354+98.965X1,紹鴨:Y=-958.732+97.546X1+58.218X6。運用各回歸方程,為下一步蛋鴨選育提供數(shù)據(jù)參考。3、選取荊江鴨、山麻鴨和紹興鴨,采取單、雙籠不同模式下飼養(yǎng),比較不同品種蛋鴨不同飼養(yǎng)模式下的蛋品質(zhì)差異。結(jié)果為:雙籠飼養(yǎng)蛋殼厚、蛋比重大,適宜種鴨種蛋選育,雙籠組各項蛋品質(zhì)指標(biāo)整體上均呈現(xiàn)一定程度上優(yōu)于單籠組;通過對各品種青、白殼蛋品質(zhì)測定發(fā)現(xiàn),蛋殼厚度和蛋殼比重青殼要顯著高于白殼,說明運輸與保存中青殼會更占優(yōu)勢,蛋白、蛋清、蛋黃比率無顯著差異,說明內(nèi)部蛋品質(zhì)差異不顯著。4、選取山麻鴨做品種內(nèi)人工授精試驗,探究籠養(yǎng)蛋鴨人工授精中的采精頻率及不同稀釋液、輸精量、輸精頻率等因素對受精率和孵化率的影響。結(jié)果表明:山麻鴨公鴨間隔兩天(每三天)采精能夠獲得較好的精液品質(zhì);生理鹽水稀釋液10倍稀釋輸精量0.1mL/羽的條件下,輸精間隔3天,可以獲得較優(yōu)的生產(chǎn)效果。
[Abstract]:Our country is a big country of egg duck breeding in the world, and has abundant variety resources. Egg duck breeding needs abundant water, land, manpower and other resources. Jiangxi, as an agricultural province with abundant water resources, is short of egg duck breeds. It is of great significance to improve the utilization rate of resources and production efficiency for the development of agricultural aquaculture in our province. In this study, the weight, body size and egg quality of Jingjiang Duck, Shan Ma Duck and Shaoxing Duck were measured and analyzed. At the same time, artificial insemination technology of caged Shan Ma Duck was studied. Most of the work was done in Jiangxi Tianyun Duck Farm, and the egg quality was determined in Jiangxi Agricultural University. The main results were as follows: 1. The body weight of Jingjiang Duck, Shan Ma Duck and Shaoxing Duck was measured. The growth and development of different breeds were analyzed by using three nonlinear models, namely, Gompertzia Gompertzia Von Berbertalanffy. The results showed that the Logistic model of Shanma duck and Jingjiang duck was better than that of Shaoxing duck, and that of Shaoxing duck was better than that of Shaoxing duck, and the 蠂 2 goodness of fit test was also performed on Jingjiang duck, mountain Ma duck and Shaoxing duck. It was found that Jingjiang duck and Shaoxing duck could obtain better fitting degree by Gompertz model analysis. The body weight and body size of Jingjiang duck, Shanma duck and Shaoxing duck were measured. The regression equation was established by regression analysis. Jingjiang Duck: yang-446.850 92.891X4 154.873X6, Mountain Sparrow Duck: -714.354 98.965X1, Shaoxian Duck 97.546X1 58.218X6. The regression equation was used to provide data reference for the next layer duck breeding. Jingjiang duck, Shan Ma duck and Shaoxing duck were selected and raised in single and double cages. The egg quality of different breeds of laying duck was compared under different feeding modes. The results were as follows: the egg shell was thick, the egg proportion was large, the double cage group was suitable for breeding duck eggs, and the egg quality index of the double cage group was better than that of the single cage group to some extent, and it was found that the quality of green and white shell eggs was better than that of the single cage group. The thickness of egg shell and the specific gravity of egg shell were significantly higher than that of white shell, which indicated that the green shell was more dominant in transportation and preservation, and the ratio of protein, egg white and yolk had no significant difference. The results showed that the difference of internal egg quality was not significant. 4. The insemination experiment was conducted in order to explore the effects of the frequency of spermatozoa collection and different diluents, insemination amount and insemination frequency on the fertilization rate and hatching rate. The results showed that the semen quality of male duck was better than that of normal saline dilution solution (10 times dilution of 0.1mL/ feather) at the interval of 2 days (every 3 days), and a better production effect could be obtained when the interval of insemination was 3 days.
