【摘要】：試驗(yàn)通過研究納米維生素A和普通維生素A對(duì)肉雞生產(chǎn)性能、免疫器官指數(shù)、脛骨灰分鈣磷含量及組織和血清中維生素A含量的影響,來評(píng)定其相對(duì)生物學(xué)效價(jià),為維生素A的選用提供理論依據(jù)。試驗(yàn)采用單因素完全隨機(jī)試驗(yàn)設(shè)計(jì),將300只健康、體重基本一致的1日齡AA肉雞隨機(jī)分為10個(gè)處理組,每組5個(gè)重復(fù),每重復(fù)6只雞�；A(chǔ)日糧以玉米、豆粕為主,其中1~5組在基礎(chǔ)日糧中添加普通維生素A(750、1 500、2 250、3 000、3 750IU/kg);6~10組在基礎(chǔ)日糧中添加納米維生素A(750、1 500、2 250、3 000、3 750IU/kg),進(jìn)行為期21d的飼養(yǎng)試驗(yàn)。結(jié)果表明:普通維生素A和納米維生素A能顯著影響料重比、肝臟維生素A水平和腎臟維生素A水平,且料重比隨維生素A添加量的增加顯著線性減少,肝臟、腎臟維生素A水平隨維生素A添加量的增加顯著線性增加。應(yīng)用斜率比法得出納米維生素A的相對(duì)生物學(xué)效價(jià)0.957(料重比)、1.816(平均體重)、1.858(日增重)、0.679(肝臟維生素A)、0.779(腎臟維生素A)、0.690(血清維生素A)、1.243(脾臟指數(shù))、0.854(法氏囊指數(shù))和3.133(灰分鈣比例)。研究結(jié)果表明,納米維生素A較普通維生素A的生物學(xué)效價(jià)高,以平均體重和日增重為評(píng)價(jià)指標(biāo),納米維生素A的生產(chǎn)性能的相對(duì)生物學(xué)效價(jià)估測為1.816和1.858。
[Abstract]:The effects of nano-vitamin A and common vitamin A on performance, immune organ index, tibia calcium and phosphorus content, tissue and serum vitamin A contents in broilers were studied to evaluate their relative biological titers. To provide the theoretical basis for the selection of vitamin A, 300 AA broilers of 1 day old, which were healthy and of similar body weight, were randomly divided into 10 treatment groups with 5 replicates in each group. The basal diet was corn and soybean meal. Among them, 1 / 5 group (n = 5) added normal vitamin A 750m 1 500 ~ 1 500m 2 2503000U / kg / kg ~ 610 to basal diet to add nanometer vitamin A 750g / kg / kg / kg ~ (-1 500) to basal diet for 21 days. The results showed that: normal vitamin A and nanometer vitamin A were fed for 21 days, and the results showed that: normal vitamin A and nanometer vitamin A were added to the basal diet for 21 days, and the results showed that: normal vitamin A and nanometer vitamin A were added to the diet for 21 days. Can significantly affect the ratio of material to weight, The liver vitamin A level and kidney vitamin A level, and the ratio of feed to weight decreased linearly with the increase of vitamin A supplementation. Kidney vitamin A level increased linearly with the increase of vitamin A supplementation. The relative biological titer of nano-vitamin A was obtained by slope ratio method. The relative biological titer of nano-vitamin A was 0.957 (average weight gain was 1.858) (daily gain was 0.679 (liver vitamin A + 0.779). Vitamin A 0.690 (serum vitamin A 1.243) (spleen index: 0.854 (bursa of Fabricius index) and 3.133 (ash / calcium ratio)). The biological titer of nanometer vitamin A was higher than that of common vitamin A. the average body weight and daily gain were used as evaluation indexes. The relative biological titers of production performance of nanometer vitamin A were estimated to be 1.816 and 1.858 respectively.
