2、分為兩組，每組50只。其中試驗(yàn)組飼喂華佳飼料，對(duì)照組飼喂正大飼料，來測(cè)定華佳飼料和正大飼料對(duì)白羽父母代肉種雞產(chǎn)蛋性能的影響和經(jīng)濟(jì)效益方面的差異。結(jié)果表明：在試驗(yàn)期內(nèi)，試驗(yàn)組相比對(duì)照組平均產(chǎn)蛋率降低了5.33%(p0.05）。飼喂華佳飼料比飼喂正大飼料的總支出少121.70元只均多盈利1.03元。說明在生產(chǎn)性能方面華佳飼料明顯差于正大飼料，但是在經(jīng)濟(jì)效益方面華佳種雞場(chǎng)生產(chǎn)的飼料飼喂的白羽肉雞父母代種雞比購買正大飼料飼喂的白羽肉雞父母代種雞

3、所獲得的經(jīng)濟(jì)效益好，能夠?yàn)殡u場(chǎng)帶來更大的利潤。關(guān)鍵詞：華佳飼料；正大飼料；白羽父母代肉種雞TwokindsoffeedonwhitefeatherbroilerparentstocklayingperfmanceZHENGBaoyu(MajinAnimalScienceintheCollegeofAnimalScienceTechnologyofGansuAgriculturalUniversityGansuLanzhou，730070
