1、蠅蛆喂雞對(duì)雞蛋品質(zhì)的影響摘要本實(shí)驗(yàn)選擇1日齡身體健康、產(chǎn)蛋性能相近的普通草雞雛雞240只,隨機(jī)分為6組,每組40只,根據(jù)我的試驗(yàn)題目選取其中兩組(對(duì)照組和蠅蛆組)。對(duì)照組飼喂基礎(chǔ)日糧;試驗(yàn)組在基礎(chǔ)日糧中添加蠅蛆。預(yù)飼期為3天,正飼期為22天。通過(guò)測(cè)定試驗(yàn)雞的蛋品質(zhì)、蛋的橫徑、蛋的縱徑、蛋殼厚等指標(biāo),計(jì)算出蛋形指數(shù)(縱徑/橫徑),研究在日糧中添加蠅蛆飼料對(duì)對(duì)蛋雞生產(chǎn)以及雞蛋品質(zhì)的影響,并對(duì)其機(jī)理進(jìn)行初步探究。結(jié)果表明:①各組雞蛋的縱徑、橫徑、蛋重差異不顯著(P>0.05),但實(shí)驗(yàn)組產(chǎn)蛋率有所增加。②實(shí)驗(yàn)組的蛋形指數(shù)比對(duì)照組低(P<0.05)。③實(shí)驗(yàn)組的蛋殼厚度比對(duì)照組高
2、(P>0.05)。④實(shí)驗(yàn)組雞蛋蛋白質(zhì)含量比對(duì)照組顯著提高(P<0.05)。結(jié)論:蠅蛆生物飼料運(yùn)用于蛋雞養(yǎng)殖中,能提高雞蛋蛋白質(zhì)含量,提高雞蛋蛋殼厚度,提高蛋雞的產(chǎn)蛋性能。關(guān)鍵詞:蛋雞;蠅蛆生物飼料;蛋品質(zhì);蛋形指數(shù);蛋殼厚度MaggotchickensoneggqualityAbstractInthisstudy,1dayofageselectedhealthy,normalegglayingperformancesimilarto240,wererandomlydividedinto6groups40,accordingtomytestsselectoneoftwo
